Abrasive Water Jet Cutting Report Engineering Essay
Up until about the mid twentieth Century the bulk of production relied on ââ¬Å" two traditional procedures of forming and machining ( Tlusty, 2000 ) . Forming is the procedure of altering the form of the whole work piece, whereas machining removes merely certain, and desired countries. Whilst these cardinal procedures still form the really anchor of contemporary production, there has besides been the demand for new procedures to be developed. The traditional procedures, as highlighted above, have a figure of built-in restrictions which limit their application to industry. In the instance of conventional machining procedures, a crisp film editing tool is used to organize a bit from the work by shear distortion. This consequences in the formation of high forces together with the corresponding mechanical energies. Together with this are a figure of extra jobs that can originate. Due to sum of energy required to transport out the operation, a physique up of unwanted heat can happen, which frequently leads to deformation of the work piece and surface snap. In certain instances, the forces introduced by the procedure are highly high and in order to procure the work piece considerable clamping forces are required ; this excessively can take to deformation. Together with these restrictions, the development of stuffs with belongingss of high strength, high hardness and high stamina has driven the debut of untraditional machining methods. Nontraditional machining ( NTM ) methods have been developed since World War II in an effort to turn to machining demands which can non be carried out by conventional methods entirely ( DeGarmo, Black & A ; Kohser, 2003 ) . NTM methods provide the ability to machine: Complex geometries ; Components with an first-class surface coating ; Delicate constituents, which otherwise would non defy the clamping forces ; and Brittle stuffs or stuffs with really high hardness. There are four types of untraditional procedures ; classified harmonizing to the principle signifier of energy used to consequence stuff remotion. These include: mechanical, electrical, thermic and chemical. One procedure which falls into the mechanical class is scratchy H2O jet ( AWJ ) film editing, and will be the focal point of this study. First, and prior to discoursing AWJ, the procedure of H2O jet ( WJ ) film editing will be introduced.Water Jet Cutting ( WJC )Water jet film editing, which is besides known as waterjet machining and hydrodynamic machining, was foremost developed in 1968, followed by the first commercial system in 1971 ( Zhong & A ; Han, 2003 ) . Through the usage of a all right, hard-hitting, high-speed watercourse of H2O directed at the work piece ( surface ) , a cut is created, as illustrated in figure 1 below. In order to bring forth the all right watercourse of H2O, a nose with an gap ( opening ) typically in the order of 0.1 ââ¬â 0.4mm is used ( Groover , 1996 ) . Together with this, runing force per unit areas of around 400MPa and above are used to supply sufficient energy for cutting to be carried out. Furthermore, the fluid of the jet can frequently make 900m/s and the cardinal procedure parametric quantities include: H2O force per unit area, opening diameter, H2O flow rate and the working or ââ¬Ëstandoff ââ¬Ë distance between the nose and the work piece. Figure 1 ââ¬â Schematic of WJC Process ( Groover, 1996 ) As the typical film editing force per unit areas as mentioned are required, a hydraulic pump is used to supercharge the fluid. The fluid is so passed through a valve, which regulates the flow rate in order to accomplish the optimal cut. The concluding phase of the fluid is to go through through the nozzle opening and impact the work piece surface from a controlled tallness.Procedure ParametersThe stuff from which the nose is made is doubtless the most of import parametric quantity in footings of procedure control ( as this greatly determines the opening diameter ) . The nozzle unit comprises of a unstained steel holder, together with a gem ; normally sapphire, ruby or diamond. Of these stuffs, diamond lasts the longest but is the most expensive. Recent progresss in the production of man-made sapphire offer this stuff as non merely the most cost effectual solution, but besides due to other advantages excessively. Man-made sapphire can be machined moderately accurately and besides has a high opposition to have on. The most common causes of nozzle failure are due to sedimentations come ining the fluid watercourse, therefore underscoring the demand for high degrees of filtration of the fluid prior to pressurisation, to cut down nozzle wear. With proper nozzle design a tight, coherent waterjet can be produced and maintained really accurately. When transporting out the cutting procedure, both the opening diameter and the ââ¬Ëstandoff ââ¬Ë distance must be closely monitored to keep a changeless deepness of cut. As the nozzle wears, compensatory alterations in the draw tallness must be made. Although existent draw distances vary from beginning to beginning, distances in the order of millimeters are normal ; normally around 0.25 ââ¬â 3.5mm.WJC: Advantages and DisadvantagesWJC offers many advantages over conventional machining methods. This machining procedure provides the ability to cut stuffs without firing or oppressing the work piece. Furthermore, no important heat is generated, therefore, deformation is minimised and in some instances, eliminated. Unlike machining or grinding, no dust is produced ensuing in small environmental pollution. Other advantages include minimum material loss and easiness of mechanization when used with numerical control and industrial automatons. Whilst such advantages exist, one of the chief disadvantages to H2O jet film editing is that there are merely a limited figure of stuffs that can be cut economically ( MTU, 2009 ) . Although it is possible to cut tool steels utilizing this procedure, the provender rates have to be greatly reduced and therefore the edged clip increased. This, in kernel, consequences in a high cost procedure. Such stuffs that can be cut utilizing the H2O jet procedure include: plastics, fabrics, complexs, floor tiles, rug, leather and composition board.Abrasive Water Jet Cutting ( AWJC )To allow the film editing of difficult stuffs such as ceramics, metals and glass, together with those softer stuffs, for illustration froth and gum elastic, the WJC procedure requires the add-on of scratchy atoms, therefore organizing the scratchy H2O jet ( AWJ ) cutting technique. In a similar mode to WJC, the procedure is carried out utilizing a high-pressure, high-speed watercourse of H2O ; nevertheless, the discrepancy being that an scratchy stuff is dra wn in by a vacuity, which is created by jet watercourse. Figure 2 ââ¬â Schematic of AWJC Process ( Meier, Louis & A ; Pilot, 1995 ) Figure 2 illustrates a typical apparatus for transporting out scratchy H2O jet film editing. It can be seen that this follows closely the agreement of WJC equipment, nevertheless, with the add-on of a twosome of cardinal characteristics ; viz. the scratchy eating system and a ââ¬Ëcatcher ââ¬Ë , which is required to protect the environment from the high energy jet.Procedure ParametersAs antecedently highlighted, the WJC procedure depends on a figure of parametric quantities. Whilst many of these are movable to the AWJC procedure, there are besides add-ons to reflect the alteration in cutting method. Momber & A ; Kovacevic ( 1998 ) present a list of such parametric quantities, which can be seen in figure 3 below. Figure 3 ââ¬â AWJC procedure parametric quantities ( Momber & A ; Kovacevic, 1998 ) Although it is by and large accepted by many writers including JankoviAâ⬠¡ ( 2008 ) that the nose or opening diameter is the cardinal film editing parametric quantity, in the instance of AWJC, the abradant besides has considerable influences on the quality of the cut achieved. A choice of the parametric quantities as listed above has been explored in the subsequent subdivision, followed by an overview of the entire system control in the subdivision thenceforth.Procedure Parameters: Overview of Observed InfluencesThe most of import parametric quantity, by far, is the orifice diameter. The deepness of cut is straight relative to the opening diameter ; nevertheless, making an optimal point at big diameters. Although related to pump force per unit area, figure 4 below clearly illustrates this point, demoing how the deepness of cut varies with opening diameter. Figure 4 ââ¬â Influence of opening diameter on the deepness of cut ( HeI?ling, 1988 ) Another parametric quantity that is closely linked to the opening diameter is the focal point diameter. This component of the cutting equipment determines the strength of the watercourse, therefore holding a direct consequence on the material remotion rate as shown by figure 5 below. Figure 5 ââ¬â Influence of focal point diameter on the volume remotion rate ( Blickwedel, 1990 ) The focal point diameter is of import non merely in footings of the volume remotion rate but besides the deepness of cut. Figure 6 below shows how the deepness of cut is besides determined by this parametric quantity ; diminishing as the focal point diameter additions. The lessening in deepness of cut following an optimal point is realised by Himmelreich ( 1992 ) and has been attributed to high grades of turbulency. On the other manus, a peculiarly little focal point diameter gives rise to particle hit and clash, giving an inefficient procedure. Figure 6 ââ¬â Influence of focal point diameter on the deepness of cut ( HeI?ling, 1988 ) Of the cutting parametric quantities listed, the crossbeam rate can be said to hold the greatest influence on the film editing procedure, followed closely by the draw distance. Both of these parametric quantities are controlled by machine design and therefore are bound by the makers ââ¬Ë specification. Figures 7 and 8 overleaf illustrate the influence of both the crossbeam rate and draw distance. It can be clearly seen that the deepness of cut lessenings as the crossbeam rate additions, following closely that of a squared map. However, on the other manus, the relationship between the draw distance and the deepness of cut is moderately additive ; with the deepness of cut decreasing as the draw distance additions. A big figure of scratchy stuffs are available for usage in AWJC. Typically these are loosely categorised as either oxides or silicates and there are, in a similar manner to the whole procedure, many parametric quantities that determine the features of an abradant. Figure 7 ââ¬â Influence of crossbeam rate ( left ) and standoff distance ( right ) on the deepness of cut ( Blickwedel, 1990 ) Whilst it is hard to state precisely which parametric quantity has the greatest influence on the procedure, it is clear that both the hardness of the stuff together with the atom form and size, need consideration. Typical hardness values vary from 30 HV for Cd up to 200 HV for B carbide ( Kriegel & A ; Palmour, 1961 ) . Figure 8 shows the influence of both the atom form and size, whereas figure 9 overleaf high spots the significance of the mass flow rate of abradant on the deepness of cut achieved. Figure 8 ââ¬â Influence of abradant ( atom ) diameter and size on the deepness of cut( Ohlsen, 1997 ; Oweinah, 1989 )Figure 9 ââ¬â Influence of scratchy mass flow on the deepness of cut( Oweinah, 1989 )Abrasive Water Jet Cutting: Associated ProblemsIt is clear from the old subdivision that there are many parametric quantities that have an consequence on the AWJC procedure. If such parametric quantities are non carefully controlled, so the efficiency of the procedure decreases along with the quality of the machined portion. Some of the associated jobs are presented in table 1.Problem and definitionParameter ( s ) affected byConsequence on constituentTaper. This characteristic arises due to a difference in the breadth of the cut at the top surface and the bottom surface and is given as a ratio ( besides flank angle ) . Abrasive mass flow rate Focus diameter Standoff distance Trave rate This characteristic determines the dimensional truth of the portion. Initial Damage Zone. Abrasive atoms impact the surface at normal angles doing craters and abrasive-wear paths. Standoff distance Focus diameter ( Abrasive atom size ââ¬â composite stuffs ) Some fictile distortion can happen. Change ( debasement ) in surface roughness/waviness. Trave rate Focus diameter/length Abrasive mass flow rate Abrasive atom size/type Surface belongingss of stuff are non as desired. Decrease in fatigue life of cut stuff due to check formation. Abrasive atom size Fatigue life reduced. Onset of stress-corrosion snap. Surface indurating due to procedure. Abrasive stuff Variation of hardness at distance from cut. Micro-structural alterations: Surface checking Phase alterations Abrasive-particle fragment implanting Delamination in composite stuffs Burr formation Assorted Assorted Table 1 ââ¬â Problems that can originate when transporting out AWJCAbrasive Water Jet Cutting: Control MethodsTo guarantee such issues as those mentioned in table 1 do non happen, accurate control mechanisms must be in topographic point. There are many supervising mechanisms in topographic point today, some of which have been briefly described below. These methods lead to the control of the cutting procedure ; nevertheless, this is non automated in these instances. Jet-Structure Monitoring ââ¬â used to command focal point diameter. Diameter of entry to concentrate point monitored to reflect alterations of focal point diameter. Wear rate can be monitored utilizing this method. Acoustic Sensing ââ¬â used to supervise overall focal point conditions. System based on the fact that a alteration in the focal point conditions ( orifice diameter and concentrate diameter ) affects the sound generated by the system. Figure 10 ( overleaf ) illustrates the difference between the acoustic form of a new and worn nose. Inductive Measurement ââ¬â used to supervise scratchy H2O jet speed. Method requires magnetic scratchy atoms. Abrasive jet is encircled by two little spirals, which is connected to a detection system. When the atom passes through the spiral, a little electric signal is created and the velocity determined. Figure 11 shows the typical apparatus of equipment, in this instance. Besides, laser systems similar to the above, nevertheless utilizing light pulsations alternatively. Material-Removal Visualisation ââ¬â used to supervise material remotion rate. In a similar mode to Acoustic Sensing, noise of cut is monitored. Frequency of signal indicates type of cut ( inter-granular/trans-granular failure ) and therefore determines the efficiency of the cut. Workpiece Reaction Force ââ¬â used to supervise deepness of incursion and surface topography. Empirical expression that takes into history all input parametric quantities excepting the crossbeam rate. Can go a force-feedback system ; leting parametric quantities to be modified to cut down the force. Figure 10 ââ¬â Acoustic form for new and worn nose ( Kovacevic & A ; Evizi, 1990 ) Figure 11 ââ¬â Initiation monitoring system ( Swanson, Kilman & A ; Cerwin, 1987 ) The above systems offer a chiefly generic attack to system patterning and supply small or no feedback. Modern control of AWJC makes usage of an intelligent monitoring and control system, which has full feedback capablenesss. Such an illustration by Srinivasu & A ; Babu ( 2008 ) utilises two systems: machine-vision based monitoring and intelligent control. The vision based portion monitors the size of the concentrating nose and the control system, which uses unreal nervous webs, continually modifies each parametric quantity to accomplish the best cut. A full analysis of this system is nevertheless beyond the range of this study. Abrasive Water Jet Cutting: Overview of Applications The applications of AWJC are huge, covering industries such as aerospace, automotive and electronics. It is beyond the range of this study to cover any peculiar country in important item ; nevertheless a few illustrations have been given below. Traditional and perchance even simple procedures have been ignored, and alternatively this study concentrates on a few non-standard applications.Meat CutingOne application of AWJ cutting is in the meat processing industry. Harmonizing to Wang & A ; Shanmugam ( 2008 ) , meat film editing is an of import activity and factors such as the cost, the presentation and sliting all need consideration. In this instance, salt is used as an scratchy and really good quality cuts, when compared to conventional film editing and even plain H2O jet film editing, can be achieved.Crunching Wheel ProductionThis illustration is slightly different to all other applications of AWJC as in most instances a through cut is desired. Axinte et Al. ( 2009 ) present an turn ing application, whereby crunching wheels are shaped harmonizing to their specification. Whilst this is considered a niche market, the writers conclude that AWJC has non merely the economical but besides proficient advantage for fabrication of this constituent. Assorted determining operations can be carried out, ensuing in such merchandises as figure 12 below. Figure 12 ââ¬â Examples of crunching wheels manufactured utilizing AWJC ( Axinte et al. , 2009 )Polishing of SteelAnother application of AWJC is smoothing, and in peculiar steel. Yan et Al. ( 2008 ) describe this application, foregrounding that electrical-discharge machining ( EDM ) is normally used for mold production. The writers province that EDM typically leaves a brickle recast bed ; taking to the application of this smoothing method. When compared to traditional methods, AWJC has a lower scratchy ingestion and recycling is improved. In this illustration the abradant is SiC and to help the procedure is covered in wax. This consequences in a much finer surface coating.Complexs ProcessingThere are many applications of AWJC in relation to complexs treating as in some instances traditional single-point film editing procedures can non be used. For illustration, Komanduri ( 1997 ) describes that it is non possible to machine SiC whisker-reinforced aluminum oxide with a single-poin t film editing tool ; nevertheless, that it may be possible to determine by crunching. Whilst some complexs can be approached in this manner, rapid tool wear is experienced and therefore the debut of AWJC is a much better method.DecisionThe old subdivision provides a figure of non-standard illustrations where AWJC is being used. Although these give a general overview, AWJC can besides be used for alternate machining procedures, such as: milling, turning, piercing, boring ( although non level bottomed holes ) and thread film editing ( Momber & A ; Kovacevic, 1998 ) . Although such procedures as above can be achieved, in a similar instance to before there are many parametric quantities that need to be monitored. This is possibly a downside to this untraditional method unless modern control methods are introduced. Further disadvantages of the procedure include the fact that degradable stuffs can non be cut and the surface coating of machined constituents relies to a great extent on the procedure. Possibly the most important consideration of using this procedure is the apparatus cost ; which can be highly high in certain instances. One other disadvantage is the noise created by this fabrication procedure. Although, as highlighted above, there are many factors that control the procedure its application to modern industry has grown significantly since its debut in the 1970 ââ¬Ës. This has been driven chiefly by technological promotions, therefore leting this procedure to be developed, but besides due to of all time germinating stuffs that serve technology applications of today.

A review on delay-minimized routing protocol in mobile cognitive ad hoc networks
A review on delay-minimized routing protocol in mobile cognitive ad hoc networks Mobile Cognitive Ad Hoc Networks is one of the cognitive radio networks which is the advanced networking technologies for spectrum scarcity problem constrain in the Federal Communication Commission (FCC). The cognitive radio networks are the cognitive network which abjects its network parameters with respect to the network environment. In cognitive radio network two users namely the primary and secondary or cognitive users will access the available spectrum to communicate each other when the spectrum is accessed by the primary user the secondary user must leave the spectrum and access the spectrum when spectrum holes available for transmission. So routing is challenging issues in cognitive networks and it is very challenging in mobile cognitive networks due to the node mobility, primary user interface and spectrum scarcity in this paper some routing protocols based on mobile ad hoc cognitive networks and a review on the delay-Minimized routing protocol are presented. Cognitive Radio Networks (CRN) is the new technology used to overcome the spectrum scarcity problem in current wireless networks by the Federal Communication Commission (FCC). In cognitive radio network is a network which has primary and secondary users which access the network based on Dynamic Spectrum Access (DSA). The primary user is the licensed user and secondary user is unlicensed user when the licensed user is accessing the spectrum the unlicensed user are not allowed so the secondary user has to sense the spectrum periodically to find the presence of primary user, presence of primary user is in dynamic in nature so the spectrum holes created by primary user is dynamic so the Cognitive user uses the DSA. While using the DSA routing is the challenging in cognitive radio networks. Classification of Cognitive radio networks Cognitive Radio Networks (CRN) is of infrastructure and infrastructure less, in infrastructure network it has a fixed structure like base station primary users secondary users and so on, in infrastructure network it has no fixed structure. Centralized and Decentralized networks the Centralized network is the network in which has on the base station in the central and have primary users are present. The decentralized network is the network which has no centralized base station and has the secondary users to communicate and primary users Static and dynamic networks the static networks the position of the base station, primary users and secondary users are fixed but in the dynamic (Ad-Hoc) the position on primary users and the secondary user will change (Mobility is nature). Routing in Cognitive radio networks Routing in Cognitive radio networks is based on available spectrum and knowledge of spectrum to nodes in the network. Routing solutions for the Cognitive radio networks are of two types one is Full Spectrum Knowledge routing and second is Local Spectrum Knowledge routing. Local Spectrum Knowledge routing has Minimum Power Routing, Minimum Delay-based Routing, Maximum Throughput-based Routing, Geographic Routing and Class-based Routing. Spectrum-Aware Routing (SPEAR) Spectrum-Aware Routing (SPEAR) is an on-demand and link-based protocol support end-to-end throughput by integration of flow-based and link-based approaches, it used RREQ for route discovery by control channels it takes decisions with the collaboration of PHY and MAC layers it handles mobility issues with Timeout field in periodic channel reservations messages. It takes the best path by maximum throughput, minimum hop count and link quality it has a communication overhead by route setup and route tear down. Spectrum-Aware Mesh Routing (SAMER) Spectrum-Aware Mesh Routing (SAMER) is a link state routing protocol with a minimum hop count and spectrum availability it gives end-to-end thought with the path with high spectrum availability, long-term stability and short-term opportunistic utilization of spectrum. The routing decisions are taken by PHY and MAC layers. Spectrum-Aware On-Demand Routing Protocol (SORP) Spectrum-Aware On-Demand Routing Protocol (SORP) is an AODV protocol with control channel which uses the path delay and node delay (switching and back off delay) for path selection. In route discovery phase RREQ message is broadcast with an SOP append in the packet the control channel exchange the routing protocol messages and it gives end-to-end thought put SORP doesnââ¬â¢t have link failure handling mechanism. Multi-hop Signal-transceiver Cognitive Radio Network Routing Protocol (MSCRP) Multi-hop Signal-transceiver Cognitive Radio Network Routing Protocol (MSCRP) is an AODV protocol with on control channel. It is a spectrum aware routing and leaves/ joins messages of the nodes so it has the communication overhead of RREQ. In the route discovery phase, all nodes append their sate information and available channels set. The routing decision is taken with the collaboration of MA C, Physical and Network Layers. Routing in Opportunistic Cognitive Radio Networks Routing in Opportunistic Cognitive Radio Networks is an on-demand graph-structured network protocol which uses the routing metric based on the probabilistic definition of available capacity over channel it has no link failure handling capacity and it discovers the route by using OSPF, Dijkstra-link algorithm. By using this Dijkstra-link algorithm it gives end-to-end throughput Local Coordination Based Routing and Spectrum assignment in Multi-hop Cognitive Radio Networks Local Coordination Based Routing and Spectrum assignment in Multi-hop Cognitive Radio Networks is a modified version of AODV which is on-demand routing protocol it has full mesh topology which uses channel scanning and beacon broadcast for neighbor discovery with control channel used for load balancing in routing. The route discovery is done by using RREQ and route decision is based on MAC and Network Layer. It has a link failure handling capability which gives less end-to-end delay and performance. Multipath Routing and Spectrum Access (MRSA) Multipath Routing and Spectrum Access (MRSA) is Mesh routing protocol based on round robin fashion data striping with minimum hop count by route discovery with control channel, Broadcasting RREQ messages. The messages sent to nodes periodically it can handle path failures by sending RERR messages and it has a communication overhead based on multiple flows on a single radio. Cognitive Tree-based Routing (CTBR) Cognitive Tree-based Routing (CTBR) is the tree-based routing protocol with centralized routing it broadcast the root announcement (RANN) message periodically with a packet and used cumulative metric for path selection. It selects the path based on local and global decision schemes. It does not have a route recovery mechanism to handle link failure s and it has a control bytes transmission overhead. Fault-Tolerant Cognitive Ad-Hoc Routing Protocol (FTCARP) It is a fast and efficient routing protocol for route recovery in presence of path failures during data delivery. It uses different route recovery mechanisms for different path failures. Cognitive Destination Sequence Distance Vector (C-DSDV) Protocol It is a table-driven routing protocol. To optimize the system performance of multi-hop CR ad-hoc networks by using multichannel routing table are updated immediately when there is a change in channels the techniques is that combines the routing and channel allocation. In route discover phase common control channel use to broadcast the route updating in the routing table in this protocol best path selection is based on sequence number. In C-DSDV channel switching is used to improve the system performances. If there are more primary users routing overhead will be increased Cognitive Ad-Hoc On-demand Distance Vector (C-AODV) Protocol Cognitive Ad-Hoc On-demand Distance Vector (C-AODV) Protocol is based on AODV a wireless network protocol it is designed according to avoid primary users activates regains for routing formation and packet discovery. It gives the minimized route cost by forwarding packets through the joint pat h and channel selection at each node it takes the advantage of the availability of multiple channels to improve the overall performances. SER-Spectrum and Energy Aware Routing Protocol SER is an on-demand routing protocol which provides high throughput in multi-hop networks it selects an energy efficient route and assigns channels and timeslots for a connection request. The communication segment assignment algorithm is used for balances traffic load among the CR users. In route discovery phase it broadcasts Route Request Messages to other nodes so it has routing overhead of RRE, RREP, RERR and ROP messages. GYMKHANA Protocol GYMKHANA is an on-demand routing protocol and an enhanced version of AODV used the GYMKHANA algorithm using virtual graphs and evaluate the cost by using the Laplacian matrix. It has a secondary userââ¬â¢s self-interference overhead. UNITED NODE Protocol UNITED NODE Protocol is a distributed and efficient based interference-aware routing protocol. It incorporates the spectrum availability cost and interference metrics into the routing algorithm to find better routes between the nodes it repairs routes by using route preservation method. It provides adaptability to the environment and increases throughput and reduces data delivery latency. DELAY-MINIMIZED ROUTING PROTOCOLS FOR MOBILE COGNITIVE RADIO Ad-Hoc NETWORKS POPCORN Protocol ROPCORN Protocol is the on-demand routing protocol which was designed for data transportation using link modeling and used to minimized delay for a set of users in the network. It broadcast the packets in link with the low cost and no primary user is affected. POPCORN is based on RACON protocol it uses buffers in the intermediate nodes and forwards the packets there is no overhead due to the use of spectrum availability and load estimation, the optimal route selection is based on the spatial or temporal locality of link disconnection. SEARCH A Routing Protocol It is the on-demand routing protocol and an enhanced version of AODV which is based on the geographic routing and follows the greedy forwarding and PU avoidance for joint channel-path optimization algorithm to find the best path. SEARCH undertakes both the path and selection to avoid PU activity region and tries to maintain end-to-end latency it has routing overhead due to the RRE, RREP, RERR and ROP messages. Link Prediction-Based Ad aptive Routing Link Prediction-Based Adaptive Routing is based on the link-availability prediction. The link ââ¬âavailability prediction considers primary user activity and user mobility. This routing reduces the energy consumption and gives the least delay by enhances network performance. It works based on link prediction and topology control Joint Routing and Channel Assignment Joint Routing and Channel Assignment (JRCA) approach based on delay prediction and a heuristic algorithm which used the collision probability and Link Stability Prediction. It is an on-demand routing protocol which user AODV type of routing with heuristic values and can find out the path with minimal end-to-end (e2e) delay. Adaptive Delay Tolerant Routing Protocol (ADTRP) The ADTRP algorithm finds a stable sequence of instances of the mobile graph and the communication topology of interest such that the number of transitions from one instance of the topology to another in the sequence is the global minimum. The algorithm uses the average lifetime of the mobile graphs in the stable sequence for communication topology and it is a generic for a stable sequence of any communication topology it uses the heuristic topology for routing so it improved throughput, better packet delivery ratio, decreased packet drop and reduced delay. STOD-RP: A Spectrum-Tree Based On-Demand Routing Protocol STOD-RP is an on-demand routing protocol which was designed for reduces the control overhead and average end-t-end delay minimization and it is an extension of the original Ad-hoc On-demand Distance Vector (AODV) protocol which uses spectrum tree addresses, spectrum decision and route selection in an efficient way for this route matrix is used. Fast and efficient spectrum-adaptive route recovery method is used when the path is damaged. In routing is challenging issues in cognitive networks and it is very challenging in mobile cognitive networks due to the node mobility primary user interface and spectrum scarcity this paper concludes that every protocol is designed for overcome certain problem in networks one is for multiple problems and one is for single problem like improving performance, minimized end-to-end delay, overall throughput increasing and so on. There is a for more protocols or improved versions of protocols for increasing problems and recruitments. In further work on this paper, a delay minimized routing protocol is proposed and implemented that improved version protocol in NS3 will be presented

The Beginning Of Civilization Essay Example | Topics and Well Written Essays - 500 words
The Beginning Of Civilization - Essay Example Native- Americans were not civilized before colonization by Europeans. As written by Vitalis, that Dodge played a vast role in separating Indians and whites. Dodge was part of the Indian Commissioners Board that ensured that Native Americans were evacuated from the lands. This was seen as a way of clearing the path for expansion towards the west as well as forcing the Indians to adopt a settled lifestyle. This, according to Vitalis, would lead to an eventual civilization of the Indians. Missionaries would introduce industrial arts, as well as the rudiments of writing and reading to enhance civilization. (Vitalis, 2007 pp38, 39)The Europeans also argued that the Native Americans did not have proper housing and that they had ââ¬Ëheathenââ¬â¢ rituals. Other areas from which the Europeans came up with their conclusion was the Native Americansââ¬â¢ military tactics, governance, economies, and families. The English, by the 18th century, had specifically a way of ranking human soci eties in terms of their cultural complexity. They had the tendency of defining cultural complexity on the basis of economic terms.Native- Americans were not civilized before colonization by Europeans.

This, according to Vitalis, would lead to an eventual civilization of the Indians. Missionaries would introduce industrial arts, as well as the rudiments of writing and reading to enhance civilization. (Vitalis, 2007 pp38, 39)The Europeans also argued that the Native Americans did not have proper housing and that they had ââ¬Ëheathenââ¬â¢ rituals. Other areas from which the Europeans came up with their conclusion was the Native Americansââ¬â¢ mi litary tactics, governance, economies, and families. The English, by the 18th century, had specifically a way of ranking human societies in terms of their cultural complexity. They had the tendency of defining cultural complexity on the basis of economic terms. The English concluded that hunting, as well as gathering, was the least complex basis of economies for societies. The herding of livestock, farming and lastly, the mixed economies of manufacturing, commerce, and agriculture followed suit. By this, they meant that the mixed economies characterized by commerce and agriculture were the most economically complex societies. Therefore, this portrayed cultural complexity too. Thus, the people who were ââ¬Ëuncivilizedââ¬â¢ and ââ¬Ëheathenââ¬â¢ did not have an absolute title to the land they occupied. (Perdue and Green, 2007 p12)à Therefore, while forming the most comprehensive conclusion, according to these views by authors, thus, the Native Americans were not civilize d. Thus, it was the European colonization that changed them into a civilized society.

Current prison population Coursework Example | Topics and Well Written Essays - 250 words
Current prison population - Coursework Example Such issue has been the primary consideration of some international and local authorities in formulating ways to enhance their correction system and the enforcement of their own laws. Some writers were puzzled of the primary cause of this consistent rise in prison rate despite the allocation of huge amounts for the corrections all over the country. An author cited that this phenomenon is due to the sentence length of crimes even for non-violent ones such as simple theft and drug possession (Pelaez). However, it could also be concurred that the lack of focus for rehabilitation is the major reason. It is said that restorative justice is better than just focusing on the effects of imprisonment as the primary form of punishment in a society. Rehabilitation of offenders by gaining back the societyââ¬â¢s confidence towards them is seen as an effective approach to crime prevention. Despite these criticisms, it can be observed that police officers in such state are active enough in loc ating offenders during a crime and hence, very dependable. The rise in the prison rate can be seen as a sign of good criminal enforcement system in the United States. However, their punishment system should be revised to consider the importance of rehabilitation than just mere imprisonment.

Ourselves Alone by Anne Devlin Research Paper Example | Topics and Well Written Essays - 1250 words
Ourselves Alone by Anne Devlin - Research Paper Example The setting of the play is generally around Andersonstown, West Belfast, with succinct side tracks to South Belfast and Dublin. The play has been produced, directed, and enacted manifold times. One presentation is by Crash Box Players and Lost Angels, directed by Steven Friedland, and produced by Kathleen Dunn, Laura Niemi and Elise Robertson. The cast of the play includes Jake Alston (as Danny/Second Soldier), Kelly Boulware (as Cathal/First Soldier), Ed Cunningham (as John McDermot), Kathleen Dunn (as Donna), Darrel Guilbeau (as Gabriel/Policeman), David Lane (as musician), Jack Mungovan (as Liam/Musician), Laura Niemi (as Frieda), Elise Robertson (as Josie), Joel Stoffer (as Joe Conran), and Joseph Whipp (as Malachy). The cast is very talented, giving extra beauty to the theme of the play. The play made its appearance in London during 1985-86. Anne Devlin, the daughter of a controversial labor leader in Belfast, Paddy Devlin, has attempted to accomplish a surmountable job telling the story of the Belfast when it was seeing some of the worst days of its history, through weaving of the story related to three Catholic women, whose lives underwent many changes brought about by the ongoing incidents and happenings in Belfast. Anne Devlin shows, in the play, how men reveal their macho by converting the society into a war zone. These men also included those who were struggling for the Irish independence, who were unknowingly converting the community into a zone of never-ending siege. Culture was being ignored. Family lives were suffering. ââ¬Å"â⬠¦where women suffer a double oppression--subjugated as much by their brothers, fathers, husbands, and lovers as by the Brits. Ourselves Alone tries to expose the ugliness of the Belfast blood knotâ⬠, writes Adler (para.2). It was hard to decide where Belfast was heading to. The storyline revolves around three ordinary Catholic women, including two Andersonstown sisters, Donna and Josie McCoy, and their brotherâ⠬â¢s wife, Frieda, who has been a Long Kesh prisoner, as shown in the playââ¬â¢s early scenes. Donna is kind of superficial, Josie possesses a strange hidden agenda, and Frieda is shown struggling with life in order to bring up her infant alone, when her husband is in prison. Friedaââ¬â¢s pro-IRA father has disowned her, and she wants to be a singer but her father sends her into the arms of a Workers' Party organizer and anti-IRA zealot. All three of the Catholic women wish and struggle to escape the political peril that is affecting their lives, but they cannot take a step because they are bound to the family loyalties residing in their hearts. Their complex relationships with men are also a hurdle. Donna waits for her lover for five years who is in prison, but when he comes out of the jail, she finds that he is not the kind of man who was worth waiting for. Josie has been a courier when rebellion against the British was going on, and has interest in politics of the trouble going in the Ireland; yet, she is trapped inside her wish for a romantic relationship. She fancies the men in her life, who are there to subjugate her. She is in love with an IRA leader, but is also in a relationship. She gets pregnant with her partner. What is interesting about the play is that Devlinââ¬â¢s Catholic women are not the rebellious heroines of the Ireland. Instead, they are making victims of themselves by not reacting against the harsh circumstances, keeping
Endangered language.-----sermo vulgaris Essay Example | Topics and Well Written Essays - 1250 words
Endangered language.-----sermo vulgaris - Essay Example The language was mostly spoken at home or in social gatherings where people had the freedom to talk without following certain rules as it was with the classical Latin. Language spoken and not written was highly diluted by other languages and could not be easily traced. The original composition of the language is not concrete because its earlier existence was not recorded. Sermo Vulgaris spread to various parts of the world but mostly to areas that traded with the Roman Empire. Because of the trade relations that existed among nations that traded with the Romans, they had to integrate Sermo Vulgaris in their languages for them to effectively trade with the Empire. The empire also took many nations captive and they were forced to learn their language for them to communicate effectively. Political interactions and positions in various areas that were close to the empire also influenced the spread of the language (Nancy & Thomas, 1983). Social interactions among the normal people in the Roman Empire and other commoners in other communities also influenced the growth of the language. It was further widely spread to other countries because of their integration with other cultures and social groups. The Romans who spoke Sermo Vulgaris played a great role in the diversification of the language. However, despite its massive growth, there came a time when the language started diminishing from its people. The language slowly degraded because of several factors. The changes made by the soldiers of the Roman Empire played a part in the extinction of Sermo Vulgaris. When the Roman Empire interacted with people of other nations, Sermo Vulgaris became a weak language. The correlation between Sermo Vulgaris and other languages led to the dissolving of the language leading to its slow and lingering death. Since the language was not written down, its survival depended on

Leadership Essay Example | Topics and Well Written Essays - 1000 words - 1
Leadership - Essay Example I started working at that restaurant from the age of sixteen as a first delivery personnel. Gradually, I got promoted and finally got the position of Assistant Manager. The duties and responsibilities of Assistant Manager included coordinating between the waiters and the kitchen, making sure that all the orders are filled in tie and waiters do not make any kind of mistake pertaining to filling the orders. Another responsibility was related to the decors of the restaurant and reporting any problem that might arise on the part of waiters or any other workers. Apart from me, there was also another Assistant who had the responsibilities of the kitchen supplies. Our manager was very proficient in running the restaurant. The manager was authoritative in nature and he wanted the instructions to be pursued in great detail. We were not allowed to make decisions on our own as there was no delegation at all. He did not have the habit of taking his assistants into confidence. The main objective of managing and maintaining the restaurant definitely got accomplished easily due to this style of leadership of our manager but his subordinates used to get highly disappointed with him including me, the other assistant and the waiters. Slowly and gradually, everyone started having problems with him as he was way more authoritative and wanted everyone to follow his instructions. Other workers used to manage somehow, but were very disappointed with the behavior of our manager since I had the habit of doing work based on my own decisions. Due to this, I started having serious conflicts with my manager. My job was also in danger as humiliating or unethical behavior with senior staff could cost me a loss of a good job. The situation got more serious when during a busy weekend I was asked by my manager regarding assisting the cashier when I was already on my toes in performing my old duties and, therefore, I did not have enough time for new responsibilities. At first, I politely refused him but he did not want to understand my position. I told that I was already busy in my previous duties but he was committed to his statement that only I had to help the cashier. That situation led to conflict between me and my manager and we argued with each other for about 30 minutes. At last, I had to obey his command and I was compelled to follow his instructions. I had decided in my mind that I had to talk to senior manager related to this issue. The next day, I went to the senior manager and told him the entire situation. At first, he also gave the glimpse of being an authoritative leader but later on he understood my view point and called the manager. We both were in the cabin of our Senior Manager and my manager was continually debating and arguing with him. Making someone understand a simple thing was never been so difficult for me. With all due respect, he was not only authoritative but also very stubborn. Anyway, the senior manager provided us both the list of duties of assistant manager and asked to follow the duties which were mentioned in the list. The list consisted of duties and responsibilities for both: the manager and the assistant manager. I was a bit relaxed that now the problem has been solved to certain extent and from now I will try to have minimal interaction with my manager, though it was not possible practically. To certain extent, I learnt to compromise and I had to kill my own ideas, feedback and

Gardner's Multiple-Intelligences Theory Research Paper
Gardner's Multiple-Intelligences Theory - Research Paper Example The theory identifies nine fundamental traits of intelligence, namely spatial, mathematical, kinesthetic, linguistic, musical, interpersonal, intrapersonal, existential and naturalistic intelligence. (Smith, 2002, 2008). Gardner never claimed that the traits of intelligence are limited to the ones he identified. Brief explanation of these types of intelligence is as follows: Spatial intelligence is concerned with the imagination. Artists are typically equipped with such an intelligence. Linguistic intelligence makes it easy for an individual to memorize difficult vocabulary and interpret thoughts into words. People with technical accuracy of thoughts have mathematical intelligence. They are good at calculations. People with quick physical reflexes have a high kinesthetic intelligence. They are good at tasks requiring physical exercises. Some people compose very good songs and have a nice taste for music and hence excel in this field. They are equipped with sufficiently high musical intelligence. People with good interpersonal intelligence level are social and have management skills. Their social circle is large. Others who are introverts have a sound understanding of their own self and have inclination towards philosophy. They have a high intrapersonal intelligence level. People who stay close to nature and appreciate it have a goof level of naturalisti c intelligence. Existential intelligence allows an individual to comprehend and interpret infinity. The Multiple-Intelligences Theory has acquired mixed reviews of the philosophers and educationalists. Although the theory has not met with great success, there are many who acknowledge the theory proposed by Gardner as presenting the matter in a broader spectrum. The approach adopted by Gardner, is indeed realistic and mature in that it identifies nearly all traits of intelligence and explains why, some people with a high IQ are not good at performing certain tasks that their counterparts with lower

The coronation explain Essay Example for Free
The coronation explain Essay Between 1947 and 1959, the amount of television licences that had been sold increased very rapidly from only 0. 1 million to almost 10 million. The coronation was in 1953 and the largest increase in the amount of televisions that had been sold was between 1953 and 1959. This tells us that most of the people that brought televisions during this time period did not only buy them because of the coronation as the majority were sold in the years following it. Therefore, from this evidence we can tell that there must have been other reasons besides the coronation why the television became such a popular accessory. In 1953 queen Elisabeth was crowned. All of the people in England were able to view this on television sets, and it became clear that seeing it on television would be a lot better, and you would see a lot more than if you went to London and saw it in real life, because obviously access to the cathedral and the grounds around it would be very limited. People idolised the monarchy, and respected them hugely. As a consequence, the amount of television sets increased that were being sold. The coronation of the queen was quite a significant reason that the number of televisions that had been sold increased so much from 1947 to 1959. However, there were a lot of other reasons resulting in huge increases in television sales. Firstly, the television was an extremely riveting source of entertainment, like it is nowadays too. Television prices also dropped very rapidly in the year or two leading up to the coronation. People wanted not only to be entertained by the coronation of the queen, they wanted more from their money, they brought televisions so as to give them more options for things to do. It was thought that children especially would benefit from the new entertainment that was given by the television, as they were expected to amuse themselves. A man in 1920 remembers what life was like for him when he was a child we played marbles, tip-cat, flicking cigarette cards, hide and seek, hopscotch, all in the due seasons. Most children could not afford wooden hoops when that season came around, but an old bicycle wheel with a tyre made a good substitute. This extract from a conversation with a friend in the 80s tells us that there were a few things for children to do, but most of them involved being outside, and to be outside, the weather must be good, and you can never rely on the weather. If it was raining or snowing and the children could not go out, it would leave very little for them to do, and the few things that they could do, would probably get boring after a while. So a television would mean that the children always had something to occupy them, and no one could ever get bored of television because there are so many different programs it was a better quality of entertainment than had been seen before. Secondly, peoples wages and liesure time were increasing at this time, which meant that more people could afford televisions when they could not before. And if they still did not earn enough to buy a television straight away because they wanted to see the coronation, they could take up the option of hire purchase. This was when poorer people who could not afford to buy a television all in one payment, were allowed to pay the shop owner who sold them the television back in smaller, more manageable instalments but people still needed these higher wages to pay the instalments. Thirdly people were beginning to be given a lot more leisure time from their employees and this meant that they needed more to occupy them and so this reason (along with their increased wages) meant that a lot more people decided to buy televisions simply because they could and because they had more spare time to watch them, so it was not a waste of money at all. Fourthly many people simply brought televisions because they were a form of new technology, and they were so fascinated by them. They wanted and needed a part of this extraordinarily intelligent machinery in their homes. Also, people were more inclined to buy televisions because the number of television transmitters increased, meaning that television was available to a lot more people, and there were a lot more programs on show. Fifthly, probably one of the most important reasons that television sales increased so much was because to have a television aerial up on your roof, was a huge status symbol, and, in the words of a man aged 60, describing his early memories of television You could tell from the aerials who had and hadnt got sets. I remember that we were one of the first three in the road to get one. If you had a car and a TV set, youd really arrived. From this extract, we can see how very important having a television was to a lot of people and just for a slightly higher status. And lastly, there were bound to be other popular national events happening that would be broadcast on television, and a lot of people also brought televisions so as to ensure that they had a television to see them. So, in conclusion, the coronation did help a little in starting the sudden rise in the amounts of televisions being sold, but mostly, people brought televisions for more personal reasons, i. e. for a better status, for better entertainment, and simply to have a little bit of the new technology that was sweeping the nation and completely fascinating everyone.

Medical Technology in Todays Society Essay Example for Free
Medical Technology in Todays Society Essay Medical technology in todays society is often seen as a treatment or cure for human health issues. The term medical technology refers to the diagnostic or therapeutic application of science to improve the management of health. Unfortunately, the negative impacts of this technology are often left unexposed to the public until too late. Medicine, such as drugs, is often perceived to be of benefit to humans as it is used to cure various diseases. On the other hand, medicine can also be highly damaging. Using medicine incorrectly; consuming it in small dosages, in excess, or using it abusively; can be injurious to peoples health. Modern medical technology can also be damaging for human well-being but this effect is not restricted to health. Throughout time people have become increasingly reliant on modern medicine. This is especially so in todays modern society. Medical intervention by use of technology has been able to help prolong many lives. An example of this is those who suffer from asthma. These sufferers may use air purifiers and/or nebulizers along with prescribed medication to help them live more comfortable and longer lives. It can be deemed a miracle that we are able to help so many people overcome their illnesses with medical technology. The current technologies available are able to do incredible things but people must be constantly aware of other modern technologies that can interfere and put the patient at risk. An example of this is the pacemaker which has the ability to save a persons life and ultimately extend it. However, external factors can interfere with medical technology and ultimately put the patient at risk. For example, radiation from everyday items such as microwaves to wireless devices such as mobile phones can affect the operation of the pace maker. Thus medical technology has a negative impact on the user of this device as it places environmental limitations on where he or she can go. Users of such a device therefore need to be continuously wary of their environment. In addition, the implementation of a pace maker prevents users from undertaking MRI scans as the process interferes with the function of the device. This is a prime example of medicine acting against itself, All medical technology needs to be treated and used with caution. Respirators need to be constant monitored and the same applies for the simplest drips. Hospitals nowadays are equipped with technology that requires the operating knowledge of hospital staff and medical professionals. The medical technology that is used in hospitals needs to be carefully monitored. Misuse could lead to an accident that has the possibility to cause a long term negative effect for the patient. It is due to the above reason that today, proficient clinical settings require the consistent expertise of all medical staff in relation to the operation of medical technology. Medical technology was invented for our health and well being. However there is always the risk of unforeseen consequences. An example of this is LASIK (Laser-Assisted In-Situ Keratomileusis) eye surgery, an operation where a patient has his or her vision corrected. Eyesight clinics advertised that the operation would improve a persons vision and give freedom to those who did not like wearing glasses or contacts all the time. Before user a laser to correct the vision the operation required the practitioner to cut open the patients corner. During the trial stages of the operation, this procedure led to several unsuccessful results where the patients suffered from extremely dry eyes, milky vision and poorer eyesight than prior to the operation. Other disastrous results included foggy visions, starbursts around lights and double vision. These after effects negatively impacted the lives of the patients greatly as they now had worse vision than prior to the operation. However, it is thanks to researchers that the medical technology in this field has advanced to a level where the risks are now minimal. These professionals are currently working on a new method of corrective eye surgery where it will not be necessary to cut open the cornea before lasik surgery is used. There will be even less of a chance that things will go wrong if the answer to this problem is found. The Gamma Ray, used to eliminate cancerous cells around the brain without the use of open surgery, is another example where medical technology could have negative effects. Its intention was to cure people with cancerous cells in places of high risk or in places that could not be safely accessed by open surgery. The risk lies in the calculation of the amount of radiation that is directed at the cancer. If there is a miscalculation the laser may destroy the cancer and other cells around it, leading to brain damage. From these two examples one can see that there is a limit to how medical technology can be used. Drugs created by medical technology are intended to help humans recover from their illness or improve their condition, however they are harmful if taken in small dosages, in excess or if used in the wrong way. For example if more that 400mg of vitamin E if is taken a day it will act as a blood thinner. Large doses of vitamin A causes heart problems. An overdose of cold and fly medications can lead to liver failure. Medicine, such as antibiotics are often perceived to be of benefit to humans as it is commonly used to treat bacterial infectious diseases. On the other hand, antibiotics can have unpleasant consequences if taken in dosages that do not completely eradicate the pathogen, thereby contributing to resistance. Antibiotics can also be used abusively when physicians prescribe the drug unnecessarily or if patients become complacent and do not adhere to the necessary antibiotic therapy. From these examples it is easy to see that medicines can cause adverse effects if taken in excess, small dosages or if used in the wrong way. Lack of funding for medical technology can cause negative effects on the genetic fitness of populations. It can bring about misleading information to the creation of a cure. As new diseases are constantly emerging, doctors, scientists and researchers need to know as much information about the sickness before they can find a cure. They need to know specific information such as the lifespan of the offending pathogen, if the disease is a virus, the exact signs and symptoms and the genetic make up before they can start research on the cure. However, lack of funds means that research projects may be delayed or even stopped before a cure is found. Researchers need the money so that they will have access to proper equipment and resources. Without it, they may not be able to conclude a research project that has the potential to find information that will lead to a cure. A major issue in medical technology is regulation. Ethical considerations need to be recognised and evaluated before research can continue. Also the lack of funding also means that cures cannot be tested thoroughly. All cures, whether they are over the counter drugs or prescription medications to medical technology (electronic thermometers), need to be thoroughly tested before they can be passed onto the market or used safely by professionals. In addition, the testing regimes may incur societal backlash due to experimentation on animals. As a result, lack of funds can prevent cures from being formed and this negatively impacts the public. Medical technology is very important for those with diseases and those who are ill or injured. For people with asthma a breathing machine may be essential for life, without it breathing may become difficult and even dangerous. Medical technology can add years to our lives and can make life better. It enables us to live past the normal expectancy of life. Technology has so many benefits. Without it we would not be able to travel, contact others around the world, entertain, or educate as well as we do. Medical technology is perhaps the most important technology of all.

We Are Surrounded By Media Sociology Essay
We Are Surrounded By Media Sociology Essay In todays world, we are surrounded by media. Our lives are saturated by newspapers, radio, books, television, movies, Internet, and many other aspects of media. These can be broadly classified into news media and popular media. In India, both these types provide an insight to Indian life, which is filled with romance, tradition, and all the other day-to-day experiences and situations one might come across. But, even though they might seem the same, they both play very different roles in society. Popular media represents and recounts a vast number of real life stories, and portrays them in a manner enjoyable for the audience. News media on the other hand, provides more facts and gives raw information for the audience to understand, with or without a firm opinion of its own on the matter. Popular media reaches out to a much larger audience, as both literate and illiterate people are able to access it, while news media only reaches out to the literate and wealthy people. This difference can become a problem in certain situations. Both these parts of media reflect society constantly, as they are shaped from and around experiences and stories of the people in the society. Usually, both these types concur with each other in the content and representation of society, but there are specific cases in which this ceases to be true. An example of this is the portrayal of the prominence and effects of the dowry system in India today. For a long time, both popular and news media reflected the aspects of the dowry system in Indian society very vividly and comprehensively, shared the same view about the topic, and thus were in concurrence with each other. But overtime, it was noticed that popular media deviated from this pattern and no longer reflected the prominence of the dowry system in society, while the news media continued to do so, thus creating an ideological difference between the two. The problem of the dowry system is still prominent, and the news media continues to reflect this. But since popular media does not reflect society anymore, a majority of the society comes under the impression that there is nothing wrong in what they are doing. This can cause the dowry system to be persistent in the everyday lives of Indian families. The dowry system is a cultural system in India in which the parents of the bride pay a large sum of money, and give expensive jewelry and other gifts such as cars, to the parents of the groom during marriage. Traditionally, there were many reasons for the establishment of this system. It was a form of inheritance for the bride, since all the family property was inherited by men. It was supposed to be the security for the bride in case any misfortune befell her husbands house. It was also a system of honoring the groom for his willingness to accept the bride as his wife in marriage, and the gifts given could range from anything significant to even a small token of good wishes. However, the greed of dowry has affected almost all ordinary families in India. Nowadays, in marriages between or amongst all hierarchal levels of society, dowry is generally an unspoken requirement. And due to the exposure to mass media, the gifts given in dowry have transformed into a large transfer of wealth, making it an important factor in marriage. The social and cultural effects of the dowry system are devastating to the society as a whole. The system reduced women to a commodity and a source of wealth. Even if the dowry is paid, in most cases, the bride is tortured by her in-laws mentally and physically as they demand for more dowry even after marriage. This torture generally leads to suicide or murder of the bride. The reason why dowry is still persistent in India is not only because it is difficult to enforce the law against it or because the grooms family is very demanding, but also because the brides family continues to bear with it. Despite the widespread awareness of the negative consequences of dowry and the problems cause by it, it is still seen as a way of buying happiness for the bride. Many families believe that giving a large dowry would result in better treatment of the daughter by the grooms family. This has only aggravated the problem as the standard for dowry became high and so marriage was dependent on whether the brides family could reach that standard of dowry or not. A study was done in 1980 which examined students expectations of dowry for people with various education backgrounds. Even though majority of the students viewed the dowry system as an evil in society and considered it unimportant for marriage, most of the brothers of the respondents gave or received dowry for their sisters marriages. Also, depending on the social status and affluence of the family, and the education qualifications of the bride and the groom, the amount of dowry needed to be given varies significantly. There is a positive correlation between a mans education and status to the dowry his family demands. As a grooms educational experience increases, the dowry demanded for the marriage also increases. In 1961, the payment of dowry was prohibited under the Indian Civil Law, and also under sections 304B and 498A of the Indian Penal Code (IPC). Despite this, this system of dowry has been a continuous and never ending menace in our society. These laws were made in order to make it easier for women to seek redress from the harassment she is under by the mans family. But these laws have been of little help to brides, who are harassed even today by their in-laws. Instances of such situations have constantly been shown to the public by the media. The power of media in todays world is surprising. The media has the freedom to form opinions, and through this they can change the opinions of people. But, people forget that in the end, all media is doing is reflecting society. The stories the media covers, and the plots of the movies that are made (except fantasy fiction of course), all are based on situations which may occur in day to day life, or real life situations. Same was the case with the dowry system. The media clearly depicted the agonies and pain of Indian women as they were suffering from the cruelties of the dowry system. This can be seen from very far back in popular as well as news media. Dowry-inspired murder cases received immense coverage by news media in the late 1970s and 1980s due to the active role played by womens organizations. The womens organizations played a very important role in increasing awareness and coverage of dowry related cases. A study done on the coverage of dowry related cases from 1979-1984 concludes that there was a noticeable improvement in the coverage of dowry in the national papers due to the womens organizations, although the coverage in regional papers remained the same. By 1979, one dowry related death received serious press coverage. A 24 year old bride from New Delhi, Tarvinder Kaur, was set on fire by her mother-in-law and sister-in-law due to the less dowry paid by her. Another significant dowry-related murder case was that of Tripti Sharma, who worked at the Ministry of Defense. She was burned to death by her husband and his family in 1986. A more optimistic and recent case is that of Nisha Sharma. In May 2003, she handed over her future husband to the police on the day of the wedding itself as he was demanding more dowry from her. This example shows what women need to do in cases of dowry abuse. Nisha refused to come under the pressures of the grooms family, and decided that she is not going to sustain it. These examples from news media are clearly reflective of the state of affairs in India at that time, and case with popular media was similar. In 1992, the movie City of Joy depicted a family which had really high dowry demands. In the movie, the grooms father clearly states, I am firm in requiring for my exceptional son the bicycle, 1000 rupees, and one ounce of gold. The brides father responds by saying, The child of a king might be worth that, and Im not even sure of that! Another 2001 movie, Lajja, clearly displayed the consequences of the dowry system, its working, and how it may be a big burden on the brides family. In the movie, Maithili (Mahima Chaudhary) is about to be married to a wealthy man of a family with a high social status. Maithilis parents give away everything they have in the dowry, including their land and saved money. Upon still falling short, they take loans from their friends, but they are still not able to gather the full amount. Maithili requests her future husband to convince his dad to let the rest of the money be, but he is too scared to do so. Seeing this, and seeing her dad beg in front of the grooms father to accept the money he has, she rebels, and calls of the wedding. She was not able to bear to see her father being humiliated in such a manner by the grooms father. Both these movies showed depicted that the brides family has to struggle a lot in order to gather the dowry for the grooms family, and thus is a big burden on them. This depiction of the dowry system by popular media was in concurrence with its reflection in the news media, but as we move ahead on the timeline, this concurrence slowly fades away. The movie Lajja was the last movie to clearly depict the pain inflicted due to the dowry system. The 2006 movie Lage Raho Munna Bhai also had the concept of dowry, but it did not demonstrate the consequences of the dowry system, and only showed that the concept of dowry existed. Since then, popular media has not depicted anything related to cases of dowry related abuse or murder. And this would have been perfectly fine if the society had transformed to this effect and there were no more dowry related crimes taking place. But this was not true, as news media still continued to report about such crimes taking place. Number of dowry cases goes up (The Hindu, January 2008); Dowry death after love marriage (The Times of India, April 2008); Harassed for dowry, teacher ends life (The Indian Express, November 2007). These are just three headlines from three of Indias popular newspapers that show the persistence of the dowry system and its consequences in modern India. Dowry is still prevalent in modern India, in not only the illiterate section of the population, but also the educated elites in Indias major metropolitan cities. Surprisingly in the past decade, the number of dowry related crime cases has actually gone up, despite dowry being banned since 1961 by Indian law. According to the statistics released by the National Crime Records Bereau, a total of 8391 dowry deaths were reported in 2010 itself, which means that a bride was killed every 90 minutes due to dowry related reasons. In 1988, this number was 2209; in 1990 it rose to 4835; in 2000 (a decade earlier), this number was 6995, and in 2007 it climbed up to an astounding 8093. According to other government records, Delhi itself records a few hundred dowry deaths every year, while womens rights groups estimate this number to be at 900 per year. This is a phenomenal increase compared to the number for the 1990s, which is about 300 per year. It is important to note that these are just official records, and are thus immensely under-reported. 90% of the cases in which women are burnt are recorded as accident, 5% as suicides, and only the remaining 5% of the cases are shown as murder. These shockingly high numbers clearly reflect the continuous increase in dowry related crimes and deaths in India. This is due to the continued commercialization of marriages in the modern Indian society. Indias economic liberalization has seen a proportionate rise in the levels of greed as compared to 1990, and a bride is now perceived by her future in-laws as a source of potential cash flow. A famous quote from former Justice Markandey Katju reads, On one hand, people regard women as goddesses, and on the other hand they burn them alive. This is against the norms of civilized society. Its barbaric. This is in response to an appeal filed by a husband who had just been sentenced to imprisonment for life by a Sessions court for burning his wife due to dowry related reasons. The effects of the dowry system are so far and wide ranging, that they can even be traced back to the womb. This system is the primary cause for female feticide and infanticide as poorer parents get to avoid the lifelong burden of saving up for the dowry for their daughters marriage. The commercialization of marriage and female infanticide is clearly reflected in the movie Matrubhoomi, in which a reverse dowry system is depicted. The movie shows a society in which there are no women left due to excessive female infanticide, and the men have grown to be so sexually frustrated, that they are ready to pay large amounts of money to get a wife for themselves or their sons. So as soon as the head of the family finds Kalki, they literally buy her from her father, by giving him five lakh rupees and five cows, and marry her to all five of his sons. Kalki simply becomes a source of money for her father, and a sex object for her husbands. Nowadays, there are famous advertisements which have been put up in many of the rural villages, which read, Spend 500 rupees today, save 5000 rupees later. This is a reference to the cost of abortion compared to the cost of the dowry which they might have to give. It basically encourages the families to come and get an abortion if their child is a girl, so that they dont have the burden of paying the dowry while getting her married in the future. This is the primary reason why India has a distorted sex ratio of 933 girls for every 1,000 boys. As is evident, the problems due to the dowry system have only been rising over the past decade. Despite this, popular media has failed to reflect these problems. News media has continued to keep up with these updates, and report about them, but popular media has deviated into its own path. Since popular media has a much larger audience compared to news media, this results in the society getting a totally different viewpoint of what is happening in their world: a wrong viewpoint in which what they are doing is not wrong. Also, since popular media has a much larger international audience as compared to news media, people from other countries get a totally different view of India: a world in which the dowry system does not exist and is not causing any problems at all. Thus, an untrue version of the society is shown to the world outside, which is not good, as when these people actually come to India and read about the truth, it is a shocking revelation for them. A shift is Indias attitude towards the dowry systems is urgently due. In simple words, dowry is equal to a family paying a man to accept their daughter as his wife, while the man along with his family, tries to get the maximum price out of the womans family. This association of economic gain with women in marriage is something which has long been persistent in India, and needs to stop. Simply making anti-dowry laws has proved to be inefficient. We need to make the society see their mistakes and realize what they are doing wrong, and this can only be done if popular media continues to reflect society as it did before. India must come together to end this practice. This could see couples channel their funds to provide education to their daughters, instead of saving money for years and years for dowry. The days of the persistence of the dowry system in India must be numbered, or Indian societys claim to be progressive is disingenuous.

Immortality Through Verse in Shakespeareââ¬â¢s Sonnet 18 and Spenserââ¬â¢s Sonn
Immortality Through Verse in Shakespeareââ¬â¢s Sonnet 18 and Spenserââ¬â¢s Sonnet 75à à à à à Desiring fame, celebrity, and importance, people for centuries have yearned for the ultimately unattainable goal of immortality. Poets, too, have expressed desires in verse that their lovers remain as they are for eternity, in efforts of praise. Though Shakespeareââ¬â¢s Sonnet 18 and Spenserââ¬â¢s Sonnet 75 from Amoretti both offer lovers this immortality through verse, only Spenser pairs this immortality with respect and partnership, while Shakespeare promises the subject of the sonnet immortality by unusual compliments and the assurance that she will live on as long as the sonnet continues to be read. Spenser debates with his lover, treating her as his equal, and leaves his opinion open for interpretation as an example of poetic indirection. Shakespeareââ¬â¢s Sonnet 18 begins with the "whim of an inventive mind," (Vendler, 120) a rhetorical question asking if he should compare the subject of the sonnet to a Summerââ¬â¢s day. After the readers see that Shakespeare does not ask to compare her to anything else, we realize that this one proposed comparison to a Summerââ¬â¢s day is, in his mind, perfection (Vendler, 120). However, in order to truly praise the woman, he must prove that she is "more lovely and more temperate" by deprecating the metaphor (Vendler, 121). Though the metaphor seems sweet at first, the implied answer is "no," and Shakespeare continues as to why she is not even worthy of the best possible metaphor (Colie, 36). His imagery of "rough winds" and the "too hot" sun together with the personification of Summer ("Summerââ¬â¢s lease hath all too short a date") support Shakespeareââ¬â¢s belief that Summer is too short and unpredictable to be compa... ...87. 36-37.

Doing Business in Europe :: Essays Papers
Doing Business in Europe 1. Common Market The first chapter deals mostly with the definition and pecularities of the so-called Common Market, formed from countries of European Union. The Common Market encloses European Union of Coal and Steel, European Economic Union and European Nuclear Energy Union. Since 1967 the European Union has the following non-national and intergovernmental bodies: Cabinet of Ministers, Commission of European Unions, European Parliament and Council of European Unions. Before the 1970, the countries of European Union were supporting the budget of European Union at the cost of their national budgets. Since April 1970, the Common Market holds its own resources independently from budgets of supporting countries. This fact makes the administrative bodies of European Union independent. 2. Tax System Common to Europe and all the world is the tax system which includes all or most of the following taxes: Income tax, Corporation tax, Trade tax, Turnover tax, Property tax, Heritage tax, Purchase of Land tax. 3. International Concerns, Transnational Corporations and their policies These include the definite politics in the field of profitability of foreign branches. The policy is aimed to gain high profits in countries with comparatively low taxes, and in the countries with high taxes the accumulated profit must be lower. The common goal of transnational corporations is, of course, to preserve the liquidity and profitability of foreign branches. Thus such branches are required to send certain information to the main office each month or each quarter. 4. World Currency System European Market is a sum of currency operations which are done at the free world market outside of native country. The international currency terminology distinguishes such currency markets as: currency markets, where the trade of foreign currencies is done within the home country, and the euromarket, where the trade of foreign currencies is done outside of the home country. 5. How to Sell in Western Market Common conditions for success are like a set of rules. The first rule states: it is comparatively easy to produce something, but selling it is a challenging task. The main principle of survival for manufacturer is to produce goods that can be sold, not to sell what the company produces. The common conditions for survival on the market include high quality of the product, fast and cheap support, satisfactory warranty period, and good marketing. Here the cultural differences must be considered, together with the information about prior experience is selling the particular product inside and outside of the home country, mentality differences, pace of progress, culture values, religion.

Opinion about parents being more involved in childrenââ¬â¢s schoolwork. Christian Startt Mrs. Pantusa English 1 A. P Prep April 26, 2013 Divorce and How It Affects Children Introduction Divorce can be the most inconvenient and hardest long-term problem of a childââ¬â¢s life, affecting all parts of his or her life all because of the parentââ¬â¢s failing marriage. 41% of first marriages end in divorce (Irvin, M), which is a substantial percentage of marriage that has not followed through with their vows and left their kidââ¬â¢s normality in the dust. Grades, emotions, and innocence all are changed in the process of the divorce, as well as a new set of challenge and problems these kids have to face in everyday life. Divorce isnââ¬â¢t just a split between a family, itââ¬â¢s more of a life changer. ââ¬Å"As soon as me and my wife Terri divorcedâ⬠, explains Chris Startt, ââ¬Å"basic life changed heavily. Laundry, cooking dinner everyday, and constantly worrying about my sonââ¬â¢s grades has really kept me busy and stressedâ⬠. I asked Chris how his sonââ¬â¢s grades were after his divorce. ââ¬Å"When me and my ex were still together, Christianââ¬â¢s grades were outstanding, strait Aââ¬â¢s. But later (a year passes) his grades went from strait Aââ¬â¢s to Bââ¬â¢s and Cââ¬â¢s later on in middle schoolâ⬠. According to Healthday reporter Alan Mozes, ââ¬Å"Children do not fall behind their peers in these areas during the potentially disruptive period before their parents divorce, the study revealed. Instead, itââ¬â¢s after the split that kids seem to have the most trouble copingâ⬠. Research suggests that the odds of a divorce occurring in a household before the children become grown rest at about 50% (Ahilburg and DeVita, 1992), with divorce rates beginning to soar in 1963 (Jeynes, 1999). A 60-year literature review of 347 experimental studies confirmed that many studies have concluded that divorce has negative consequences for childrenââ¬â¢s academic achievement (Kunz, 1992). Most research shows that the childââ¬â¢s math scores were the ones that were mostly affected. ââ¬Å"Kim found that while a divorce is in progress, first, second and third-graders experience a dip in math test scores ââ¬â a decline that holds steady once the divorce is finalâ⬠. (Mozes) But, at the same time reading scores didnââ¬â¢t really seem to be changing, as research from (Mozes) shows that ââ¬Å"â⬠¦however, Kim found that reading scores remain unaffectedâ⬠. When my parents divorced, about 6 years ago, I was 9 years old in 3rd grade and thatââ¬â¢s when my grades went from strait Aââ¬â¢s, to Aââ¬â¢s and Bââ¬â¢s, and then a C here and there. Mathematics really begun to get more and more difficult to concentrate to and the tests were getting harder to understand. Reading, however, was my strength in elementary school, and it remained un-affected after my parents divorce. Researcher Hyun Sik Kim explains, ââ¬Å"Reading is not that cumulative. But with math, you must understand previous things to develop. For example, if I do not understand that one plus one is two, then I cannot understand multiplication. Divorce really puts a childââ¬â¢s mind in motion. After the divorce the child may feel like it was his/her fault, causing stress and emotional problems. By this happening, the child will become more stressed by the moving between houses, therefor making it harder to concentrate on schoolwork and thus grades beginning to lower. My personal experiences also help support my argument. Divorce should be decided with caution; you have to think about how its going to affect your child and how its going to affect their future.

Not Only The Jews
The first research in the late 1940 s and early 1950s focused on the Jewishness of the Holocaust. Modern research has begun to deal with the suddering of other victims of the Nazi genocide. For example, homosexuals, Gypsies, prisoners of war, Russians, poles, Catholic priests, Jehovah s Witnesses and other were more or less systematically murdered as the Holocaust continued. By the end of the war, as many as 6 million of these people had been killed, along with between 5 to 6 million Jews. Roma (Gypsies) were among the groups singled out on racial grounds for persecution by the Nazi regime and most of its allies. The Nazis judged Roma to be ââ¬Å"racially inferior,â⬠and the fate of Roma in some ways paralleled that of the Jews. Roma were subjected to internment, forced labor, and massacre. They were also subject to deportation to extermination camps. Mobile killing units killed tens of thousands of Roma in the German-occupied eastern territories. Further, thousands were killed in the Auschwitz-Birkenau, Chelmno, Belzec, Sobibor, and Treblinka extermination camps. The Nazis also incarcerated thousands of Roma in the Bergen-Belsen, Sachsenhausen, Buchenwald, Dachau, Mauthausen, and Ravensbrueck concentration camps. There were nonetheless several deportations of Roma. About 2,500 Roma were deported to Poland in April and May 1940. Most of them were starved and worked to death. Those who fell sick or became crippled were shot. Another 5,000 Roma were deported to Lodz, where they were held in a separate area within the Lodz ghetto. Those who survived the horrible conditions in the Lodz ghetto were later deported from the ghetto to the Chelmno extermination camp, where they were killed in gas vans. Roma in Germany were deported to Auschwitz, where a special camp was designated for them in Auschwitz. Gypsy family camp. â⬠Entire families were incarcerated together. Twins and dwarves, however, were separated out and subjected to medical experiments under SS Captain Dr. Josef Mengele. Nazi physicians also used Romani prisoners in medical experiments at the Ravensbrueck, Natzweiler-Struthof, and Sachsenhausen camps. In German-occupied areas of Europe, the fate of Roma varied from country to country, depending on local circumstances. The Nazis generally interned Roma and later transported them to Germany or Poland for use as forced laborers or to be killed. Many Roma from Poland, the Netherlands, Hungary, Italy, Yugoslavia, and Albania were shot or were deported to extermination camps and killed. In the Baltic states and the German-occupied areas of the Soviet Union, mobile killing units killed Roma at the same time that they killed Jews and Communist leaders. Thousands of Romani men, women, and children were killed in these actions. Many Roma were shot along with Jews at Babi Yar, near Kiev, for example. The ââ¬Å"Gypsy family campâ⬠at Auschwitz was riddled with epidemicsââ¬âtyphus, smallpox, and dysenteryââ¬âwhich severely reduced the camp population. In May 1944, the Germans decided to liquidate the camp. As the SS surrounded the camp, they were met by Roma armed with iron pipes and the like. The Germans retreated and postponed the liquidation. Later that same month, the SS transferred about 1,500 Roma who were still capable of work out of the family camp. Almost 1,500 more were transferred in August. The remaining Roma, about 3,000, were killed. At least 19,000 of the 23,000 Roma sent to Auschwitz died there. It is not known precisely how many Roma were killed in the Holocaust. While exact figures or percentages cannot be ascertained, people estimate that the Germans and their allies killed between 25 and 50 percent of all European Roma. Of the approximately one million Roma living in Europe before the war, up to 220,000 were killed. After the war, discrimination against Roma continued as the Federal Republic of Germany decided that all measures taken against Roma before 1943 were legitimate policies of state and were not subject to restitution. Historians in Germany argue about how universal the historical character of national socialism was. One conservative faction would like to view the communist system as responsible for fascism. Because Marxism was victorious in Russia, the Fascist parties were able to win in Italy and Germany. This speculation claims that the destruction of social class distinctions by the Bolsheviks prepared the way for racial murders of the Nazis. The extermination of the Jews is presented as a distorted copy of a previous model, rather than as a unique occurrence. Other social scientists have protested against viewing Nazi crimes in such a relativistic way. They see an aura of normality being created and fear that the basic anti fascist consensus in the Federal republic might end. They are also apprehensive about the analogy to current politics and warn against a restoration by means of history. Extermination or Reeducation? The concentration camp was one weapon in the campaign to bring state and society into conformity with fascism. If physical extermination formed the most frightful instrument of that policy, it was not the only one. A range of attempts were made to isolate people and to use fear to inhibit ââ¬Å"undesirableâ⬠behavior. Whatever the reasons for imprisonment, all ncarcerations were the result of Nazi ideology and posed a danger to the prisonerââ¬â¢s life. The categories of prisoners differed from one another in how they were selected and treated. Those groups whom the Nazis deemed inimical but not racially undesirable were not completely rounded up, but taken only in random samples They also fared differently within the camps. Homosexuals, political prisoners, and Jehovahââ¬â¢s Witnesses are among the groups who were sent to the concentration camps for reeducation. They were supposed to renounce their particular orientation. The very fact of their incarceration estrained their ideological comrades outside the camps from becoming active in the struggle against Nazism. Democratic freedom makes pluralism possible. In democracies, deviations from the norm concern not only criminality but also sexuality, ethnicity, religion, and attitudes toward work. The Nazi system was concerned with deviations in all these areas. It classified political, sexual, religious, and working-attitude deviations in separate categories. In all probability, the Hitler state required these definitions of the enemy and was, in its own terms, correct in its choice of these groups. Within a society, minority and separation groups represent a seedbed of possible revolt. Homosexuality has always and everywhere existed. Hitler considered homosexuality as a predisposition that could not be changed. It was assumed that a homosexual orientation could not be eliminated, that only its manifestations could be blocked. Thus, the pink triangle worn by the homosexual in the concentration camp represented the Nazisââ¬â¢ intention to reeducate him. No credence was placed in a simple change of opinion by homosexuals, such as was granted to Jehovahââ¬â¢s Witnesses, who were not taken entirely seriously, or even to political prisoners. Two categories were seen among homosexuals: the constitutionally hard-boiled homosexual and the occasional offender. Since in neither case was the Aryan status of the homosexual in doubt, all could remain alive. If necessary, homosexuals were to be castrated, but they were permitted to continue to work. As a matter of policy, extermination was therefore restrained. In practice there were other contrary impulses on the part of the SS, and those who wore the pink triangle met an unusually harsh fate. The social controls directed at homosexuals within the camp represented a continuation and an intensification of social controls imposed by society at large. A nation with many children can gain supremacy and mastery of the world. A pure race with few children already as one foot in the grave; in fifty or a hundred years it will be of no significance; in two hundred years it will be extinct. It is essential to realize that if we allow this infection to continue in Germany without being able to fight it, it will be the end of Germany, of the Germanic world. Unfortunately this is not the simple matter it was for our forefathers. For them, the few isolated cases were simply abnormalities; they drowned them in bogs. Those who found bodies in the mire did not know that in 90% of the cases they found themselves face to face with a homosexual who had been drowned with all his belongings. This was not punishment, more the simple elimination of this particular abnormality. It is vital we rid ourselves of them; like weed we must pull them up, throw them on the fire and burn them. This is not out of a spirit of vengeance, but of necessity; these creatures must be exterminated.
