Existing MPPT algorithms use sequential search procedures, therefore, they may falsely operate during partial shading. The reason of this obstacle is numerous local maximums appearing in the P-I or P-V characteristic curves. This impedes conventional MPPT systems to find the global maximum (GM) and significantly restricts the ultimate electric output of PV plants.The present article proposes the improved algorithm for MPPT functionality. The method based on a photo-current estimation of each PV panel. Owing this information, submitted algorithm provides permanent assessment of the upper and the low limits of regulating parameter (a current or a voltage) between which its optimal value that ensures GM is located. Further, conventional MPPT entering the work can easily find the nearest maximum that obviously is GM.Present work describes this new method to find more accurate and fast estimations of the GM boundaries and to keep GM even during fast changings partial shading conditions, which will cause the higher overall efficiency of MPPT.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121112644","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}

Side-scan Sonar (SSS) has been found to be suitable for seabed scanning missions, however the sonar images acquired from SSS often suffer from considerable noise and geometrical distortion, which changes the understanding of the texture, size, and shape of seabed objects. In order to identify seabed objects, it is thus vital to reconstruct the actual shape by reducing distortion. This paper proposes a process for correcting and reconstructing the sonar image map that utilizes intensity normalization, slant range correction, yaw and pitch correction, and speed and location correction. This is done using navigation and inertial data acquired by the autonomous underwater vehicle sensors.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"578 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116540444","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}

RS and BCH codes are a very important family of cyclic codes, and are included in most elementary courses on code theory. One of the most important tools in decoding of RS and BCH codes was developed by Berlekamp, and later formulated as an algorithm for synthesizing short LFSR-s by Massey and is now known as the Berlekamp-Massey (BM) algorithm. An alternative algorithm for decoding such codes is the extended Euclid algorithm. We present another viewpoint to the BM algorithm which is simpler than the Massey formulation, and mirrors the extended Euclid algorithm. This presentation may replace the common treatment of the BM algorithm in elementary courses with a simpler and more rigorous presentation. Moreover, this approach enables to improve the HW implementation of BCH decoding. This is promising as BCH codes are gaining renewed interest lately in latency sensitive applications. Another advantage of the new approach is that it provides a simple derivation of erasure decoding.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125908532","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 Vienna rectifier expansion is a three-phase rectifier provides active power factor correction, while expanding the number of dc-line voltage levels from 3 to 4, 5, 6 and up to a maximum of 7 levels.

We consider the problem of designing multiple PN sequences that are to be used as pilot signals and spreading sequences for transceivers whose clocks are not synchronized.Because the transceivers are unsynchronized, there will be phase shifts between the receiver and the transmitter, and in order for such a system to work well, the PN sequences should have three properties. The pilot signal and the spreading signal that are used by each user should be (nearly) orthogonal to one another. The cyclic autocorrelation of each sequence should be as small as possible (for non-zero shifts). Finally, the cyclic cross-correlation between pilot and data sequences corresponding to different users should be as small as possible.We consider a moderately simplified version of the problem and show that drawing sequences at random can be used to produce many good sequences, and is, in this sense, better than using Gold sequences when designing such systems.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"438 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131673467","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 order to analyze propagation of EM fields these systems, Standard CMT solves 1st order differential matrix equation (Standard CMT equation). Analytical solution for this equation currently exists only for the multiwaveguide systems with dielectric function, homogeneous along the optical axis (z-axis). Coupled-mode analysis of the devices, whose dielectric function varies along the optical axis (e.g. photonic components with integrated optical gratings) till now, is only available with numerical techniques. In this work, we propose the general Analytical solution for Standard CMT equation, including the case of dielectric function, inhomogeneous in the z-direction. This solution represents an effective analytical tool for fast and accurate analysis, design and optimization of a variety of photonic components, whose principles of operation are based on the variation of their dielectric function along the optical axis.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129683840","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}
