We consider a model of interference at the sink for a layered architecture of CDMA based WSN with two kinds of interference, multiple access interference (MAI) and node interference (NI), considering power control error, path loss and shadowing. An energy model is considered for calculating the requirement of energy for successful delivery of information between two nodes. The effects of node density, correlation among MAI and NI interferers, power control error on BER, PER, average number of retransmission and energy consumption for successful reception between two successive nodes are investigated. Analytical results are verified through simulations.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"2000 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116759127","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}

Effectiveness of the treatment depends largely on this component of recovery and is unfortunately beyond the scope of continuous vigil by the doctor. The major post-operative procedure is to keep flexing and extending the fingers, either independently or with external support, usually with the other hand. The patient has to do this diligently and hence monitoring this exercise is of concern. The proposed novel idea is a monitoring system which keeps track of the movements of the fingers using linear ratiometric Hall-effect sensors (Allegro-1321) and magnets attached to the fingers. This can provide reliable data to the doctor to ascertain whether the patient is actually doing his part in effecting a speedy recovery for himself, thus improving the overall efficacy of the treatment.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125871573","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 generation from renewable sources, connected to power networks mostly at distribution level, will change the traditional power flow patterns and produce adverse power fluctuations due to its random nature. Although battery energy storage systems (BESS) can be employed to reduce power fluctuations, economic constraints imposed by the high cost of them justifies, under certain conditions, converting only a portion of available renewable energy to electricity and allowing the balance to go waste[1,2], an undesirable proposition from environmental standpoint. In this back drop, a strategy, based on the coordinated control of system elements, requiring lower BESS capacity and capable of reducing renewable energy waste, to control power fluctuations is presented and its performances under different BESS capacities and operating conditions were studied and reported in this paper. Numerical simulation carried out revealed the presence of a performance saturation linked to increasing BESS capacity. Reaching the saturation at BESS capacities, MW and MWhr, much smaller than power and energy associated with fluctuating generation, demonstrates the ability of proposed algorithm to control power fluctuations efficiently. The saturation effect further suggests that the accurate estimation of capacity requirement is necessary to obtain better cost performances from BESSs.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116007380","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}

Most of the websites use server-side scripting languages to deliver dynamic web pages to their users. The problem of implementing a chat server with these languages is that there are no long running processes to establish a firm long lived socket connection with the server. Therefore, when the server needs to send some information immediately to the web client, there should be a mechanism to do so. In this paper, we discuss our protocols and optimizing techniques for such kind of server-client environment. The target of this project is to use our protocol to design and implement an optimized web chat client and a server using a server side scripting language.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122790527","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 standard treats all packets generated while browsing the internet as delay tolerant packets and classifies them as Best Effort (BE) packets. This includes BE packets generated while browsing secure websites. However, secure transactions are governed by time constraints as they take place within a secure session. Expiration time for secure sessions varies based on application/server. For high priority Secure Sessions the expiration time can be very short. In a highly congested network a Subscriber Station (SS) may not get enough BE bandwidth and hence might not be able to transmit these secure and delay sensitive packets leading to session termination which will lead to failed transactions resulting in unsatisfied users. In this paper we propose classification of Secure-HTTP and Secure-WAP packets as RTPS packets and moving them to RTPS queue so that they receive higher priority. The simulation results reveal that when the system contains 20 SS with one session per SS in progress, and when Secure-HTTP/Secure-WAP packets are treated as priority packets like RTPS, there is an increase in throughput for secure packets by 340 Kbps and decrease in delay by about 1.54 seconds per SS.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128204994","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}

A country like India, most of the people use more than one language in their day to day life; the requirement of OCR system is very much essential. There is not much work in developing OCR system for south Indian languages such as Kannada are reported in the literature. Recognition of the Kannada character is more complex and challenging, because it has large set of character with more similarity in properties among characters and characters belonging to same class have higher variability among different set of fonts. Moreover, the Kannada characters are formed by combination of basic symbols; a natural approach for recognition is to segment characters into basic symbol and recognize each symbol subsequently. Therefore a character level segmentation method is highly desirable. Also precise segmentation will certainly reduce the number of classes to recognize. The naïve use of characters images for segmentation may not yield more accurate results. With previous studies which have confirmed that the multi-channel Gabor decomposition represents an excellent tool for image segmentation and texture analysis, we propose a novel character segmentation method using Gabor filters. On comparing with manually segmented benchmark data we obtained overall accuracy of 93.82%.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121740785","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}
