One successful manufacturing process is the heating of the mould surface by infrared heaters located above the mould. We will describe one model of mould warming, as well as a method to calculate the heat radiation intensity on the mould surface in order to pinpoint the location of infrared heaters. During the calculation of heat radiation intensity across the mould surface, we will use experimental measured values for the heat radiation intensity from a sensor in proximity to an infrared heater. It is necessary to maintain approximately the same heat radiation intensity across the whole mould surface during warming process. The model described in this article allows us to optimize the infrared heaters' location for this purpose. In this way, we obtain the same material structure and color tone across the whole surface of an artificial leather. We will apply a genetic algorithm to optimize the heaters' location. A computational procedure of heat radiation intensity across mould surface and heaters location optimization was programmed in the language Matlab. The last chapter provides a practical example with a description of the solution.","PeriodicalId":343071,"journal":{"name":"2012 ELEKTRO","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131076630","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 model used contains a second order unstable, linear, dynamical system, in a negative feedback loop with a nonlinearity comprising a linear gain in parallel with a “signed square”. This mimics, what is referred to by Alim Louis Benabid, the great pioneer of deep brain stimulation as “excitation of inhibitory pathways that lead to functional inhibition”. Describing function analysis is used to give a very close estimate of the inherent, almost sinusoidal oscillation, which is quenched by deep brain stimulation. The relationship between the critical amplitude of deep brain stimulation (expressed either in volts or milliamps) and the fractional pulse width needed for quenching the oscillation is derived. This is fitted as closely as possible to experimental results by Benabid et al., by minimizing a sum of squared error index.","PeriodicalId":343071,"journal":{"name":"2012 ELEKTRO","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125407687","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}
