Among the most serious limitations facing the success of future consumer gas identification systems are the drift problem and the real-time detection due to the slow response of most of today's gas sensors. We reviewed gas identification approach based on a microelectronic gas sensors technology and GMM. And found that performance is achieved using GMM with a success rate of 94% obtained for different principal components which is much better response with respect to other well known traditional as well as advanced pattern recognition algorithms such as KNN, MLP, SVM, and PPCA. This points out to an important result, which suggests that higher generalization performance can be obtained by using feature reduction and selection techniques as preprocessing techniques. Using the operating temperature as a parameter to tune the selectivity of the sensor chip to different target gases was also proven to be an effective way to improve performance of the overall system. This approach is able to overcome drift problem.","PeriodicalId":179541,"journal":{"name":"2009 International Multimedia, Signal Processing and Communication Technologies","volume":"216 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122384266","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}

Also unintentional jamming can be present due to co-existing systems at the same band, whereas intentional jamming arises mainly in military applications. Independent Component Analysis (ICA) use as an advanced pre-processing tool for blind suppression of interfering signals in direct sequence spread spectrum communication systems utilizing antenna arrays. The role of ICA is to provide an interference-mitigated signal to the conventional detection. Several ICA algorithms exist for performing Blind Source Separation (BSS). ICA has been used to extract interference signals, but very less literature is available on the performance, i.e., how does it behave in communication environment. This needs an evaluation of its performance in communication environment. This paper evaluates the performance of some major ICA algorithms like Bell and Sejnowski's infomax algorithm, Cardoso's joint approximate diagonalization of eigen matrices (JADE) algorithm, Hyvarinen's fixed point algorithm, Pearson-ICA algorithm and Comon's algorithm in a communication blind source separation problem. Independent signals representing sub-Gaussian, Gaussian and mix users(sub-Gaussian, super-Gaussian and Gaussian) are generated and then mixed linearly to simulate communication signals. Separation performance of ICA algorithms measure by performance index.","PeriodicalId":179541,"journal":{"name":"2009 International Multimedia, Signal Processing and Communication Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127593706","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}

Application developers mostly rely on third party middleware, tools and libraries (i.e., web servers, distributed middleware such as CORBA, XML etc.) to respond the emerging trends of their target domain. With this middleware we tried to enhance the efficiency of application by decrease their memory uses, data processing and decision making on another web module which is independent of each application. In our middleware system, we also proposed an application by which we can find some important conclusion about different health status likewise ECG, Accelerometer. etc., which can be used in various data processing and determine the current health status. In this paper we also analyze some different low level and high level middleware technology which were used to build different kind middleware likewise CAMUS, MiLAN and try to find the best solution in the form of middleware for Ubiquitous Healthcare Information System. T build our Middleware we also analyze different application such as Matlab, Oscilloscope, and JFreeChart and try to extract most common feature, and then try to build a advance LiveGraph which consist most of the common feature of above and also have some advance feature which is most feasible to analyze the data and to take some decision itself.","PeriodicalId":179541,"journal":{"name":"2009 International Multimedia, Signal Processing and Communication Technologies","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116690531","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}
