Improvement in efficiency is obtained by utilizing symmetry planes, implemented in a new manner. Unlike well known solution, the symmetry planes are defined by modification of the original matrix problem using orthogonal matrix projection. Such a formulation allows, beside substantial reduction in number of variables and efficiency gain, precise alignment of electric and magnetic walls in the mesh.","PeriodicalId":285174,"journal":{"name":"2009 19th International Conference Radioelektronika","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132707001","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}

Currently it operates ten particle accelerators, a new linear injector for H- acceleration is under construction and two future machines are in the study and research phase. Radio frequency systems are a vital part of almost all particle accelerators. The RF systems at CERN cover a frequency range from a few kHz up to 30 GHz, and a power range from the noise levels up to hundreds of MW in a single structure. The Low-Level loops of the RF systems accommodate a wide range of electronics from purely analogue circuitry dating back to the 60's up to state of the art remotely operated digital systems based on the most recent FPGA and DSP technology. This paper provides a short overview of the RF systems of the CERN synchrotron particle accelerators with emphasis on the specific problems and issues typical for each accelerating stage in the chain.","PeriodicalId":285174,"journal":{"name":"2009 19th International Conference Radioelektronika","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121987317","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 main point of interest is safety of MRI diagnostics and the influence of cellular phones on the device operation. In this article a wide band behavior of pacemaker lead is discussed, in order to categorize potentially dangerous frequency bands. Medical and engineering sciences use completely different methodology, so there is no unique answer if the malfunction of the pacemaker, even when occurred, brings potential risk to a patient. Tests of radiation from the pacemaker lead in wide frequency band, presented in this article show that interaction between the device and external RF field is possible, especially for frequencies over 1GHz. These tests could be potentially good background for further clinical tests. Other observation was, that the saline solution did not significantly change the radiation from the lead, compared to the measurements in air.","PeriodicalId":285174,"journal":{"name":"2009 19th International Conference Radioelektronika","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124026607","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 domain of digital signal processing the number representation is either in fixed-point or floating-point form. In the text the algorithm for unsigned binary multiplication for fixed-point representation is presented. There are many processors with fixed or floating-point representation and there are also several blocks used for arithmetical operations in FPGA. But generally these blocks do not have a large variability in terms of bit width. The goal of the contribution is mainly to present an arithmetical model and to evaluate its complexity for a large number of possible implemented algorithms. For testing of product algorithm the multidimensional convolution of gray scale images was performed as well.","PeriodicalId":285174,"journal":{"name":"2009 19th International Conference Radioelektronika","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127523491","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}
