The localization refers to the extrinsic calibration of a network i.e., the recovery of relative position and orientation of each camera in the network on a common ground plane coordinate system. To this end, Kalman filtering is initially used to model the observed trajectories in each camera's field of view. This information is then used to estimate the missing trajectory information in the unobserved regions by integrating the results of forward and backward linear regression estimation from adjacent cameras. These estimated trajectories are then filtered and used to recover the relative position and orientation of the cameras by analyzing the estimated and observed exit and entry points of an object in each camera's field of view. We fix one camera as a reference and find the final configuration of the network by adjusting the remaining cameras with respect to this reference. We evaluate performance of the algorithm on both simulated and real data and compare the results with state-of-the-art approaches.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121325845","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}

Lot of research has been carried out regarding development of its necessary components such as the antenna array, transmit/receive module (TRM) and processor unit. The cost, efficiency, wide bandwidth, and fabrication technology for the TRM have been pursued as key research areas. Cost reduction techniques till date have focused on the use of high tech MMIC fabrication techniques. Literature lacks in guiding a novice design engineer working on TRM in a cost effective manner. This paper presents mathematical analysis of signals processed in a TRM to enable a design engineer understand the constraints involved in the system design. The behavioral simulation, at 2.0 GHz, of TR module has been performed and, simulated results of phase shifter and TR switch sub-modules are also presented. Detailed system simulation is performed using lumped components for cost effective implementation in a lab environment. The results depict a close realization of the mathematical formulation.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116434331","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}

Healthcare domain is facing challenge of finding healthcare information that meets user requirements. Semantics can provide interoperable, automated and seamlessly meaningful communication for healthcare domain. Healthcare information is increasing with the increase of medical databases over the internet. In this matter provision of right information to appropriate users over the web is a great challenge. Semantic web technologies can address this issue by ensuring extensible, flexible and efficient information discovery related to diseases and clinical processes. We proposed a semantic registry that will be a service registry as well as metadata registry.

Secondly, which SR technique will produce SR image that is more appealing to human eyes? For resultant SR image, EBSR predicts the relation between high and low frequencies in an image, whereas RBSR algorithms rely on a sequence of frames. From the experimental results on test images, we find that compared to RBSR, EBSR preserves the structure of the original image. Knowing this capability is important for detection and recognition systems. In terms of visual appearance, RBSR is preferred except when there are large motions in consecutive frames. Moreover, the aliasing artifacts cannot be removed by EBSR algorithms.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132479384","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}

Many cryptographic schemes based on FCSRs have been proposed in the open literature. The most efficient attack against ciphers based on FCSRs are ‘linearisation attacks’, which consists of three variants, namely ‘Conventional Linearisation Attacks (CLAs)’, ‘Fast Linearisation Attacks (FLAs)’ and ‘Improved Linearisation Attacks (ILAs)’. This paper describes applications of linearisation attacks on F-FCSR-16 key-stream generator. For this purpose, the paper presents State Recovery Algorithms (SRAs) based on CLAs, FLAs and ILAs for F-FCSR-16. The paper also presents efficient techniques of implementation for these attacks on F-FCSR-16 type key-stream generators. Further more, the paper also presents a comparative analysis of the results of CLAs, FLAs and ILAs on F-FCSR-16 key-stream generator. This analysis shows the trade-offs between CLAs, FLAs and ILAs in terms of data time and memory complexities, when compared with each other and determines the relative efficiency of these attacks on F-FCSR-16.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126192760","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}

QEMU can emulate numerous target architectures. Like many other open source projects, available documentation of the software is either scant or stale. Modifying and extending such code becomes especially challenging due to the sheer size of the code base (654K lines of code spread over 1251 source files). Sporadic or no developer support makes things even more challenging. Therefore, a team of developers is effectively left with the source code to understand it and to correctly change it without causing any regression bugs. We overcame this challenge using methodical software engineering techniques. This paper discusses various problems that we encountered and solutions that we employed. In addition, we present QEMU's software architecture, which we constructed in a bottom-up manner using source code. We believe that such experiences are relevant for understanding and extending any software of substantial size.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126669078","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}

Trimming a query can potentially reduce the answer size that is required to retrieve from a remote server. Existing query trimming technique is based on Boolean logic, which inhibits several shortcomings such as after trimming it expands number of predicate terms and induces disjunction even if conjunctive queries are under consideration. It trims the query segment wise and can not process the combined semantics of all the segments in a cache. In this paper we propose a query trimming technique that is based on variation of modeling approach (graph based) used for satisfiability and implication testing. We demonstrated with a case study that our proposed technique overcomes limitations of the previous query trimming technique and hence improves semantic cache query processing.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125935444","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}

MATLAB is extensively used in a number of scientific fields, such as digital image processing, digital signal processing, mathematics (just to name a few). The significance of MATLAB's programming is its rich library of built-in functions that provide programming ease. However, MATLAB uses an interpreter which slows down the processing, especially while executing loops. This becomes a performance bottleneck in programs that make excessive use of loops. In the field of digital image processing, for example, the operations performed on a matrix usually involve many nested loop structures. Therefore, MATLAB is often exposed to the issues of slow execution and memory latency. In order to accelerate MATLAB's processing, we utilize NVIDIA's CUDA parallel processing architecture. We demonstrate that interfacing MATLAB with CUDA and parallelizing the most time-consuming portions of MATLAB's code, the processing can be speeded up significantly. As a proof of concept, we present some results of JPEG compression with MATLAB using CUDA. Not only our results show a significant performance boost in MATLAB's processing, but are also in perfect agreement with quality.","PeriodicalId":167049,"journal":{"name":"2011 7th International Conference on Emerging Technologies","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127982660","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}
