In present scenario the governments are driving to generate electricity with renewable energy technology. Electricity regulators are proposing new regulations to motivate small scale investors and entrepreneurs to invest in the installation of microgrids of 0.5 to 5 MW capacity in order to promote further renewable energy generation. At the same time, strict guidelines is being issued for the appropriate design of the microgrid. There are various design parameters need to be evaluated before the installation of these microgrids. Electromagnetic transient (EMT) analysis is one of the useful tool for evaluating peak voltage, current and insulation coordination for the microgrid. This work focuses to design EMT simulation framework on object oriented platform. The object oriented solver (OOS) is lightweight so it can be executed with processors such as Intel Gallilio and Raspberry-Pi etc. A comparative study of OOS and MATLAB based EMTP-type simulation framework has been presented in tabulated form.","PeriodicalId":336454,"journal":{"name":"2019 29th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127226479","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 this paper, we propose two PRNGs by combining/modifying Blum-Blum-Shub (BBS), Xorshift and Permuted Congruential PRNGs. The first one is for general purpose applications and the second one is for low-power IoT applications. We implement the proposed PRNGs on FPGA ZedBoard Zynq™–7000. Our implementation results show that the proposed PRNGs generate 4.83 × 107 and 4.29 × 107 random numbers per-second, respectively. The total dynamic power consumption of the proposed PRNGs is 17mW at 48.31Mhz and 16mW at 42.90Mhz with a maximum throughput of 184.288MBps and 163.651MBps, respectively.

There are different methods used for estimation of object position. One of these methods is to measure an angle of arrival (AOA) of the echo signal from the object using a monopulse amplitude comparison. Based on this principle, the paper presents a method to determine the deviation angle of an object compared to the cross-over axis called beam coding technique. The technique includes an approach for generating multiple beams, which are shifted in steering angles by applying a Rotman Lens or a Butler matrix and the process to index these beams with different Pseudo-Random Noise codes. Practical measurement is conducted to evaluate the usefulness of the proposed technique. The results from the experiment show that the technique can be applied to localize the position of the moving object.","PeriodicalId":336454,"journal":{"name":"2019 29th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116937322","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 most important parameter is the reactive power of the fundamental spectral component. In this article the method of the measuring of the reactive power of sinusoidal signal, based on the integration and differentiation of one of the input signal is implemented. The implementation of this measurement method based on the first-order digital integrator and the first-order digital differentiator is taken into consideration. The digital differentiator based on the algorithm of approximation by two samples is considered. The comparison of the considered method with popular method of integration and popular method of continues time delay from the point of view of the measurement error is carried out. The analytical dependence for the calculation of the additional measurement error of the reactive power caused by deviation of signal frequency is obtained. An expression to determine the gain factors of the integrator and differentiator, which allows to minimize the measurement error of the reactive power near the nominal value of the frequency of input signal is obtained. Simulation mathematical modeling by the software package Matlab 7.0 and Simulink 8.0 is performed.","PeriodicalId":336454,"journal":{"name":"2019 29th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125939441","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 reason of its occurring is using a lens with low or variable focal length or simple camera optics. When an image captured by a camera is affected by undesired distortion and it is used for the distance measurement, it can cause significant measurement errors. The aim of this paper is to introduce a method for finding an optimal undistortion parameter for any optical distortion, which can be described mathematically. The proposed method uses the Hough transformation accumulator and at each iteration step the quality of straight lines is evaluated as a gradient from local maximum. The algorithm is verified and assessed on several images. The developed approach can be used to find the global maximum gradient in general, even when a local maximum changes its size over iterations.","PeriodicalId":336454,"journal":{"name":"2019 29th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127470109","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 amount of data to transfer for an update is reduced, the energetic efficiency is increased and as the method is designed for over the air update, the radio spectrum occupancy is decreased. Herein described approach uses Lua scripting interface to introduce updatable fragments of invokable native code. This requires a dedicated memory layout, which is herein introduced. This method allows not only to distribute patches for deployed systems, but also on demand add-ons. At the end, the security aspects of proposed firmware update system is discussed and its limitations are presented.","PeriodicalId":336454,"journal":{"name":"2019 29th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133437296","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}

On the basis of our findings, it is very useful to use polyphase codes for the radar signal detection in active noise jamming scenario and corresponding range estimation. Results of our experiment shown that the use of tested polyphase coded radar waveforms increased radar resistance against active noise jamming.

The article shows the basics of new trends in multi access networks, where effective spectrum is not an option, but a requirement. The article compares differences between fuzzy logic and game theory in channel selection. Each of these methods has some advantages and disadvantages to calculate results. Simulation shows how channels can be assigned to each node in wireless networks based on input parameters.
