This is mainly due to the computational intelligence techniques which can deliver a reasonably good result within a shorter time period by performing complex calculations with numbers of iterations. Distribution operation is a common problem in the area of supply chain management which got the attention for many years. However, up to now only simplified versions of distribution operations such as Vehicle Routing Problem (VRP), Travelling Salesman Problem (TSP) have being considered by many researches. Some of the researchers adopted with heuristic approaches such as Simulated Annealing (SA), Genetic Algorithm (GA), Tabu Search (TS) and etc. with number of assumptions. However, the standard problems are far away from the real world problem. Furthermore, when the problem size (or scale) increases, the computational time to finds the optimal results increase exponentially, hence these problems are categorized as +P-hard problems in mathematical terms. To bridge the gap between standard problems in distribution and the real world problems, in this research, the standard VRP problem is extended to multi depot environment with split delivery option and tries to investigate the applicability of Simulated Annealing (SA) and Tabu Search (TS) to find solutions to this complex problem within considerable time frame. +umbers of simulation studies are carried out with both of these techniques and results revealed that both these techniques can be adapted to complex Multi Depot Vehicle Routing Problem with Time Windows and Split Delivery (MDVRPTWSD) problem and TS out performances in solution quality.","PeriodicalId":117199,"journal":{"name":"2009 International Conference on Industrial and Information Systems (ICIIS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129611854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Image authentication is done by embedding message / image in spatial domain by choosing image blocks of size 3 × 3 from the source image in row major order. Three bits of authenticating message /image/message-digest are fabricated within each source image byte of each image block where the position is chosen randomly using a hash function b7b6b5 ⨁k where b7, b6, b5 are higher order three bits of each source image byte and k is an integer number varies from 0 to 7, and the process is repeated for the whole image. The dimension of authenticating image followed by message digest (MD) and the content of authenticating message/image are also embedded. To enhance the security a layer has also been fabricated by XOR operation of the embedded image with a self generated MD obtained from the source image. Reverse process is applied for decoding. The results have been tested through histogram analysis, noise analysis and standard deviation computation of the source image with the embedded image and compared with popular existing steganographic algorithms like S-Tools. It is seen that the proposed FBIA is capable to embed more information than S-Tools with better fidelity.","PeriodicalId":117199,"journal":{"name":"2009 International Conference on Industrial and Information Systems (ICIIS)","volume":"05 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128693215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

External pilot also interact into synthetic simulation test-bed. The autonomous control system is based on the Aerosonde UAV and major considerations of controller performance and minimum instability within manual and autonomous switching have been evaluated with full software simulation. Major requirements for the good control system are minimum overshoot, minimum setting time without undesirable oscillation and low cross coupling between high level commands. A MATLAB simulink standard configuration environment and the Aerosim Aeronautical Simulation Block Set are utilized for simulation studies, presented through a flightgear interface and Custom GUI. The AeroSim® simulation environment features a complete detailed 6 degrees-of-freedom nonlinear generic UAV model which consist earth, atmospheric, aerodynamics, inertia and equation of motion sub models.","PeriodicalId":117199,"journal":{"name":"2009 International Conference on Industrial and Information Systems (ICIIS)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128793580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a consumer's perspective, the effectiveness of multimedia delivery suffers significantly in such networks. Further, in a mobile environment, when the number of users increases, they experience interruptions in the received multimedia streams. Adaptive streaming is one solution that can be adopted in any network environment regardless of the nature of the network. Adaptive streaming can be achieved using transcoding techniques. Transcoding is a mechanism that converts a video to a form that has less information so that the resulting data volume is appropriate for streaming over a low bandwidth network. However, the quality of the video stream drops due to transcoding. The advantage is that when there is a large number of users sharing the network, users could watch a video at a lower quality with no interruption if the transcoding is applied before the video is streamed to the end user. i.e., a compromise can be made between the video quality and network delay. The main focus of this research is to analyze the variation of transcoding parameters with respect to bandwidth, in order to achieve an adaptive streaming solution of optimum achievable quality in a low bandwidth broadband network.","PeriodicalId":117199,"journal":{"name":"2009 International Conference on Industrial and Information Systems (ICIIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128657821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
