Main sources of emission are micro and macro cracks, friction and shifts. Active and passive acoustic emission methods are widely used to study the strength of materials, the landscape stability and various stages of seismic process. Geoacoustic emission is an acoustic emission of the sound range and it describes the interaction of micro and macro dislocations. Anomalies of geoacoustic signals may be earthquake precursors and they are of great interest to researchers. A typical geoacoustic signal consists of sequence of specific shape short pulses. Authors propose an additive model of geoacoustic signal. According to the model the signal decomposes into a sum of components described by the modulated Berlage and Gauss functions. The use of the matching pursuit method was offered to determine model coefficients. Unfortunately, this method has cubic computational complexity depending on number of functions on which the signal is decomposed. This article is devoted to ways to improve accuracy of the model offered by authors. Various numerical schemes allowed to increase the adaptive property of matching pursuit method with respect to geoacoustic emission signals are considered and compared.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133250754","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}

Since the power source of this device is on-board batteries the requirement for power consumption is relevant. In the course of the work the analysis of the device processes which shows that a significant current flows in the windings of the motors during the stabilizing system operation is carried out. This is the reason for the high power consumption. In addition this causes the motor windings heating which also has a negative effect on the system operation. Further in the work the factors influencing the power consumption of the device are researched taking into account the features of stabilization system implementation on a microcontroller and the features of the actuators and their control. Based on the result of this research a method of reducing ripple of the current in the motor windings is proposed and an example of its implementation in the control program of the device is given. It is shown that such system can be realized. And finally the results of measuring the supply current of the device which show significant reducing the power consumption are given.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127430319","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}

Three sources of information are evaluated: reference books on the climate, satellite meteorological data and weather stations data. In order to improve the precision of assessment, it seems expedient to combine sources of information regarding the factors that affect electric power generation by solar photovoltaic systems. The paper proposes a method for estimating electricity generation on the basis of reference information and open-access weather stations data. Assessment of solar radiation takes into account the beam, sky-diffuse and ground-reflected components. The method incorporates the impact of the total and low-level clouds on solar radiation, as well as the impact of temperature on the efficiency of solar photovoltaic systems. Assessment of solar radiation and electric power generation by solar photovoltaic systems is conducted in Narin-Kunta, a village in the Irkutsk region on the shore of lake Baikal.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115371727","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 time delay units, integrators and differentiators are used in practice to perform phase shift. However, the application of these devices is limited by the requirement of sinusoidal input signals. This paper consider the method of phase shift of one of the signals to ${pi}/2$ radian by using a digital Hilbert transformer. The application of this method allows to measure reactive power for polyharmonic input signals at the required frequency band. The effect of the order of the Hilbert transformer on the measurement error of reactive power is considered. A comparison of the digital implementation of the Hilbert transformer using the IIR-type digital filters and IIR-type digital filters is performed. The obtained analytical expression allows to estimate the error of measurement of reactive power due to the frequency deviation and phase response of the Hilbert transformer from the nominal value. Popular method of measuring of the active power based on the averaging of instantaneous power is considered. The analytical expressions relating the input signal frequency deviation and the measurement error of reactive power for the considered measurement methods are obtained. The validity of the obtained expressions is confirmed by simulation results of the mathematical modeling performed by the Simulink package software.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115726872","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}

Design optimization of sensors allows significant improvement of metrological characteristics of measuring systems on their basis. However, issues of design optimization of such sensors have not yet been considered in scientific literature. The paper deals with the design of the valve position sensor, discusses methods of optimizing the sensor design elements and presents the results of solving optimization problems. It is established that design optimization of a magnetic field concentrator makes it possible to increase the optical flux of the sensor element by 34.4%, whereas optimizing the place of installation of a magneto-optical element (MOE) (16 … 19 mm from the point of inserting optical radiation into optical fiber) allows more than a 7-fold increase of the optical flux. Optimization of the gap between the FOSF and the movable magnetic core mounted on the valve plate allows determining the zone of optimal location of the movable magnetic core on the basis of the permissible change in the FOSF transformation function (the dependence of the FOSF output signal on the position of the valve plate).","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115004833","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}
