It states that it is possible to reconstruct a signal from a number of samples below the well-known Nyquist limit. The success of the reconstruction depends on the capability of a frontend transform to represent the signal in a sparse way. In this paper, we propose the use of the discrete cosine transform (DCT) to preprocess a speech signal in order to obtain a sparse representation in the frequency domain, and thus, we show that the subsequent application of compressive sampling can represent vowels with less information than the Nyquist sampling theorem. The reader will find that the presented material differs from other speech processing techniques, as our results could be the basis for developing compression methods using the discrete cosine transform and compressive sampling. Both techniques, traditionally used for image compression, are now proposed for speech compression.","PeriodicalId":432662,"journal":{"name":"CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133085360","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}

One way environmentalists tout of being able to save the planet is through the use of solar panels or wind turbines to power one's home. Many renewable energy companies boast of being able to take one's household off the power grid or lower one's power bill by utilizing their respective renewable energy devices. This paper will explore the feasibility of these claims and determine whether it is actually economically or aesthetically possible to take one's home off the power grid and utilize a personal energy source. The areas being explored will range from wind turbines, solar panels, personal capacitor banks, solar water heaters, etc. A determination will be made at the end of the paper of whether an average family in Pensacola could indeed live off the power grid.","PeriodicalId":432662,"journal":{"name":"CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126660672","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 design process in this case is formulated as the controllable dynamic system. The conception of the Lyapunov function of dynamic controllable system is used to analyze the principal characteristics of the design process. The different forms of the Lyapunov function were proposed to analyze the behavior of a design process. The special function that is a combination of the Lyapunov function and its time derivative was proposed to compare the different design strategies that compose the structural basis of generalized methodology. This comparison has been implemented by parallel computing.","PeriodicalId":432662,"journal":{"name":"CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123683355","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 people with motor disorders can achieve better and faster results if a quantitative analysis of patient progress is carried out by precision.

This paper presents the development of a virtual laboratory involving such disciplines. The process developed is known in academic circles as “Eastman Process”. The process, model, applications and a strategy for its control are described, operational modes and how to obtain them are also described.
