Furthermore, it introduces and compares feed-in premium designs of different European countries. The main purpose of this work is to develop optimal short-term planning models for price taker hydropower producer working in the existing regimes. Those models have to deal with the high level of uncertainty which is the water power introduces into the power system. We intend to provide guidance in decision-making aimed at maximizing the profit. A detailed analysis is made of a simpler reservoir configuration, which indicates that even though the problem is nonlinear, a bang-bang type of control is optimal, where the power stations are operated at maximum rates of flow. Some simple relationships between price and timing of decisions are calculated directly. A numerical algorithm is also developed. The task of a small HPP operation regime is solved for the maximum income within the cases of the known variation of prices at the market. An optimization tool known as generalized reduced gradient method for nonlinear optimization tasks is used to plan hydropower production under uncertainties.","PeriodicalId":117147,"journal":{"name":"2014 IEEE 2nd Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126036182","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}

Thus the second order fixed-point normalized lattice-ladder neuron with its training algorithm was implemented in Artix-7 FPGA. The experiments were performed using various bandwidths and word length constrains. In general increase of word length yielded smaller mean errors. However the limited size BRAM used for trigonometric function LUTs was a bottleneck to improve the precision while doubling the number of DSP slices.","PeriodicalId":117147,"journal":{"name":"2014 IEEE 2nd Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123209526","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}

About one third of these people are people with mobility or movements impairments. First problem is that for that kind people high precision prosthetic devices with neural control and feedback are very expensive. Second problem almost all average price prosthetic devices have visual feedback system which loads user vision. To solve these two problems decided develop prosthetic devices with other kind of feedback systems: thermal, electrical, pressure, vibration...etc. For using vibration feedback system vibration motors must work in wide range of frequency spectrum and produce controlled intensity in every frequency point. Unfortunately nowadays produced vibration motors cannot satisfy these requirements. In this paper represented three possible solutions of vibration devices for prosthetic feedback systems. Loudspeaker motor based system, linear motor based system and combined system. All three systems are modelled in comsoll metaphysics environment. Modelled parameters are flux density and force-frequency dependencies. As result the best candidate for vibration system is simple voice coil motor. It has linear force-frequency spectrum in wide range. Linear motor most have complex control system and have the same results as combined motor.","PeriodicalId":117147,"journal":{"name":"2014 IEEE 2nd Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122152273","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}
