The transform coding utilizing the Discrete Cosine Transform (DCT) has been commonly adopted in the various standards for image compression. These include the CCITT standard for video telephony, the JPEG (Joint Photographic Expert Group) standard for coloured still-image transmission and the MPEG (Motion Pictures Expert Group) standard for pictures on the storage media. MPEG was originally developed for digital television, its popularity and effectiveness as a storage/transmission format and abundance of content have made it attractive for use in personal video playback devices. DCT based coding schemes are also used for higher quality applications such as HDTV. Therefore, an architecture which rapidly computes DCT has become a key component of image compression VLSIs. This paper reviews the existing efficient algorithms for implementing the reconfigurable Discrete Cosine Transform (DCT)/ Inverse Discrete Cosine Transform (IDCT) architecture for multimedia applications and proposed an algorithm which offers high speed and reduced area. The proposed architecture uses an error compensated adder tree to perform shifting and addition operations. The reconfigurable architecture not only decreases the time of research and development but also saves fabrication cost. The advantages of the proposed architecture are that this architecture does not require multipliers and ROM. It only needs adders and shifters. In digital circuits, the area of the multipliers and ROM are larger than adders and shifters.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121348237","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}

However, previous studies on bandwidth request (BR) mechanism at WWG are carried out using either polling or bandwidth reservation for best effort (BE) services. These studies suffer from low spectral efficiency with WiMAX network and cause unfairness to WiMAX MSs while contention based BR is carried out from WiMAX MS to BS (via WWG). To overcome these limitations, we suggest three variants of contention based bandwidth request namely message based BR, CDMA or code based BR and heterogeneous BR. Simulations validate the proposed mechanisms in terms of throughput, connection delay and queuing delay. It is inferred that with heterogeneous BR, the network throughput is improved by 11.21%, the connection delay at WWG is reduced by 5.85%, the queuing delay at WWG is reduced by 9.47%, the MAC delay at WLAN MS is reduced by 9.09% and the average access delay at WiMAX MS is reduced by 62.12% compared to message and CDMA based BR.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127646943","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}

Testing phase of software begins with module testing whereby, modules are tested independently to remove substantial amount of faults within a specified testing resource. Therefore, the available resource must be allocated among the modules in such a way that number of faults is removed as much as possible from each of the module to achieve higher software reliability. In this paper two optimization problem are discussed for optimal allocation of testing resources for the modular software system. These optimization problems are formulated as nonlinear programming problems (NLPP), which are modeled by a software reliability growth model based on a non-homogeneous Poisson process which incorporated Log-logistic testing-effort function. LINGO program is used to solve the optimization problems. Finally, numerical examples are given to illustrate the procedure developed in this paper. It is shown that the optimal allocation of testing-resources among software modules can improve software reliability.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128037359","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}

There has been a lot of interest in the new techniques for analyzing data. Neural networks offer a new strategy with enormous potential for many tasks in the domain of geospatial planning. ANN technique for modeling provides smaller errors in comparison to other classical methods. Neural networks have been applied to many interesting problems in various areas including road traffic noise prediction. In the present study an attempt has been made to explore the application of neural networks to road traffic noise prediction in Lucknow city, capital of Uttar Pradesh, India. Traffic volume, speed and noise level data were collected at ten selected locations. For development of model, classified traffic volume (Car/Jeep/Van, Scooter/ Motorcycle, LCV/ Minibus, Bus, Truck and 3-Wheeler), traffic speed on both sides of the road were taken as input data. Output was estimated as Leq. Performance of the model was tested by root mean square error (RMSE), mean absolute error (MAE) and coefficient of correlation (R). It was observed that there is no significant difference between observed and predicted noise levels in the present case, indicating the accuracy of model.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132122764","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}

Human computer interface such as intelligent rehabilitation aids can be controlled by eye movements. It can be helpful for severely paralyzed people. Electro-oculography is a simple method to track eye movements. Electro-oculogram (EOG) is the biopotential produced in the surrounding region of eye due to eye ball movements. The signal is easy to acquire using surface electrodes placed around the eye. This paper presents a comparative study of different methods for Electro-oculogram classification to utilize it to control rehabilitation aids. In this experiment, Electro-oculogram is acquired with a designed data acquisition system and the wavelet transform coefficients and statistical parameters are extracted as signal features. Those features are used to classify the movements of the eyeball in left and right direction. Classification is done by linear & quadratic discriminant analysis, K-nearest neighbor method, linear support vector machines and artificial neural network with backpropagation algorithm. In comparative study good accuracy (above 75%) has been observed in all cases but KNN showed better performance. Based on these classified signals control commands can be generated for human computer interface.","PeriodicalId":364589,"journal":{"name":"2012 Third International Conference on Computing, Communication and Networking Technologies (ICCCNT'12)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130435573","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}
