The preservation of temporal dependencies among continuous media and simultaneous mobile distributed sources is an open research problem. This paper proposes a temporal synchronization mechanism to be used at runtime in a MDS. The synchronization mechanism avoids the use of a common reference by executing temporal dependencies according to the causal dependencies of the continuous media data. Our mechanism is efficient in terms of processing and storage capacities used at the mobile devices, as well as the overhead attached per message across the wired and wireless communication channels.","PeriodicalId":119218,"journal":{"name":"2010 IEEE Electronics, Robotics and Automotive Mechanics Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128878662","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 reduces the overall memory elements and load. The proposal utilizes Interpolated Finite Impulse Response (IFIR) filter. The proposed structure is simplified by splitting the factorable decimation factor into two integers, i.e. $M=M_{1}cdot M_{2}$ such that $M_{1}> M_{2}$. The applied methods are multi rate techniques and number theory for digital signal processing. This proposed algorithm is applicable in communication systems like Software Defined Radio (SDR).","PeriodicalId":119218,"journal":{"name":"2010 IEEE Electronics, Robotics and Automotive Mechanics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129815438","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}

Though, the recovered axon orientations could be prone to error because of the low signal to noise ratio. Spatial regularization can improve the estimations but it must be done carefully such that real information is not removed and false orientations are not introduced. In this work we investigate the advantages to apply an anisotropic filtering based on single and multiple axon bundle orientation kernels. To this aim, we compute local diffusion kernels based on Diffusion Tensor and multi Diffusion Tensor models. We show the benefits of our approach on three different types of DW-MRI Data: synthetic, in vivo human data, and acquired from a diffusion phantom.","PeriodicalId":119218,"journal":{"name":"2010 IEEE Electronics, Robotics and Automotive Mechanics Conference","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114552612","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 a solution, the topology of the buck-boost converter with tapped inductor is studied, with the purpose of selecting the converter appropriated for an integrated PV inverter applied to residential use with connection to a single-phase grid, providing high benefits without isolation.
