Many techniques are used for energy reduction such as, dynamic power management, pipelining, transistor sizing, and clock gating. Clock-gating is the most common technique for reducing microprocessors power. This technique is widely used in digital circuits, and forms the basis of many of the other power reduction techniques; clock-gating implementation becomes an emergency-function, if the CPU is about to overheat, it's means that the CPU is stopped for some cycles and then is working for some cycles based on the supply voltage control, the CPU will consume less energy per period which reduces the total power usage of a program. This paper presents a hardware design of the clock gating technique, which enables the CPU to reduce the supply voltage accompanied with the clock frequency, based on its workload variation, which leads to a possible reduction in power requirements. Spice simulation results confirm and verify the theoretical idea and successful hardware operations.","PeriodicalId":274652,"journal":{"name":"2008 International Conference on Computer and Communication Engineering","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117104405","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}

This paper presents analysis of single and combined bit-plane performance for face recognition. Novel approach of using bit-plane as input to Feedforward Neural Network is used. Comparison is done to analyze recognition rate of using single and combined bit-planes. Every single pixel in an 8-bits gray level digital image consists of 8 bits. Among these eight bit-planes, bit-planes 4, 5, 6 and 7 provide better recognition rates than bit-planes 0, 1, 2 and 3. Feed-Forward Neural Network is used in this paper for training and testing the bit-planes. The face database used for evaluation is CMU AMP Face Expression Database, which consists of 13 subjects, with 75 8-bits gray level images from each subject. Bit-planes 4, 5, 6 and 7 achieve over 88% accuracy after 15 image samples are trained. However, by using combination of these 4 bit-planes based on majority vote, false acceptance rate (FAR) can be reduced from over 80% to 26.2%. False rejection rate (FRR) of the combined approach is 2.2% and half total error rate (HTER) is 14.2%.","PeriodicalId":274652,"journal":{"name":"2008 International Conference on Computer and Communication Engineering","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128756562","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}

As this web services is a new service-oriented computing paradigm which poses the unique security challenges due to its inherent heterogeneity, multi-domain characteristic and highly dynamic nature. A key challenge in Web services security is to design effective access control schemes. However, most current access control systems base authorization decisions on subjectpsilas identity. In this paper, we suggest web access control scheme which incorporating user password and web server log. The major objective of the proposed model is to provide mechanisms to allow control of web user access based on the user access behavior by tracking the web access history. The system controls access to web pages depending on user password, date of last request, page visited (URL) and status action. The active userpsilas access pattern is matched with user access data discovered from user access history, based on mining web usage data using association rules mining and PrefixSpan algorithms, then analyzed to make the access control decision (web access is permitted or denied).","PeriodicalId":274652,"journal":{"name":"2008 International Conference on Computer and Communication Engineering","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128151082","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 this paper, different approaches used for handwritten Arabic word recognition were reviewed. An introduction to the Arabic script is given, followed by a description of algorithms for the process involved: segmentation, feature extraction, classification, and recognition. However, an automatic recognition of text on scanned images has enabled many applications such as words spotting in large volumes of documents, automatic sorting of postal mail, and convenient editing of previously printed documents. The domain of handwriting in the Arabic script presents unique technical challenges and has been addressed more recently than other domains. Many different methods have been proposed and applied to various types of images, and a variety of approaches have been already developed, tested and returned good results. Yet the database used was too small compared to the huge size of Arabic texts, which gives way to other approaches to be developed based on a bigger database. Since handwriting recognition is such a large subject, there is plenty of scope for the work in this field. Finally, a comparison to show pros and cons of the approaches reviewed is conducted.","PeriodicalId":274652,"journal":{"name":"2008 International Conference on Computer and Communication Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130040924","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}

Nowadays endoscope procedure is followed to investigate the problems in the digestive system disorders, which is a tedious, expensive and invasive method. A non-invasive, cheap and painless method called electrogastrogram (EGG) has been devised for the detection of electrical signal cutaneously from the stomach and it is an initial mode of investigation for gastric disorders before encouraging the endoscope procedure for uncomplicated Gastric disease and benign (non cancer). The main objective of this paper is to propose a simple method of finding the digestive systempsilas disorders more easily and accurately using virtual instrumentation (VI) based EGG. The recording setup or the model explained in this proposed system helped us to record the EGG for more than hundred patients, nearly 70-75% of the patient results in digestive systempsilas disorder such as dyspepsia (D), stomach ulcer (SU), gastric esophagus reflux disease (GERD), nausea (N), cyclic vomiting syndrome, etc. For the above said digestive systempsilas disorder dissimilarity is found in its frequency, amplitude, power spectrum analysis and the statistical analysis compared with its normal individual parameter at a high fair amount of accuracy.","PeriodicalId":274652,"journal":{"name":"2008 International Conference on Computer and Communication Engineering","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134588368","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}
