Although several techniques and approaches have been proposed and applied in the last decade, data reliability in transmission is still a problem. In this paper we propose a high efficient combined error detection and correction technique based on the Orthogonal Codes Convolution, Closest Match, and vertical parity. This method has been experimentally implemented and simulated using Field Programmable Gate Array (FPGA). Simulation results show that the proposed technique detects 99.99% of the errors and corrects as predicted up to (n/2-1) bits of errors in the received impaired n-bit code.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114982882","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}

While much research has been done on multimedia compression and network resource optimization, multimedia delivery is still a big concern especially for scarce resource networks. The virtues of network aware video coding and application of domain specific compression techniques have not yet been fully explored. In this paper we propose a dynamic Network Bandwidth Allocation Scheme which deals with intelligent transmission of the video sequence over the network. We incorporate the knowledge of the network conditions to determine how various parts of the video frames are encoded. The module is called is called SDM (Smart Decision Maker) and it builds over an intelligent classification of Video into Visual Objects (VOs). An estimate of the available network bandwidth is obtained which is then distributed optimally between the different frame constituents based on their relative importance and motion.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132924223","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}

It is shown that the RF coverage footprint shrinks due to high-speed data, which can be compensated by introducing delays. The queuing theory is used to quantify the delay, where the incoming data forms a queue in a buffer and waits for radio transmission. This delay, which is a function of the bit rate, is used to compensate the deficit in the link budget. Consequently, the RF coverage foot print remains the same for all bit rates.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128812120","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}

The proposed algorithm is implemented practically using the M68000 microprocessor, the inverter is loaded by means of two types of loads, the first is resistive load and the second is a three phase induction motor. The obtained results are verified by comparison with the most known methods: sinusoidal PWM as analog method and space vector PWM as a digital one.

The WAVE protocol provides enhancements to the physical (PHY) and medium access control (MAC) layers of the existing 802.11 wireless standards. These enhancements are required to support the intelligent transportation systems (ITS) initiatives of the US Department of Transportation regarding vehicle-to-vehicle, vehicle-to-infrastructure, and infrastructure-to-vehicle communication. Many research groups have contributed to the development of the protocol. Many of the same individuals have worked to extend the ns-2 network simulator to correctly simulate wireless mobile networking, specifically vehicle adhoc networks (VANETs). The objective of this research project is to measure the performance of the WAVE protocol at the MAC layer, using the ns-2 simulator. Specifically, the simulations measure aggregate throughput, average delay, and packet loss metrics.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114910467","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}

In our study, quantitative measurement of oxygen tension in retinal vasculatures is made with the noninvasive technique of phosphorescence lifetime imaging. A frequency domain approach is used to estimate the fluorescence or phosphorescence lifetime by regression analysis. Measurements are influenced by the presence of noise due to which least squares estimation yields results with high variance. Since accurate estimates are important in the study, we propose a spatial regularization method by adding a quadratic penalty term in the cost function instead of directly using classical least squares. The effectiveness of the proposed method is demonstrated by applying it to experimental and simulated data to show improved performance when compared with unregularized estimation.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129862971","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}
