It provides tools and algorithms aiming to characterize the localized signal behavior in the joint vertex-frequency domain. Localized Graph Fourier Transform (LGFT) is an example of such a tool, with a role in the graphs signal processing which is equivalent to the role of the Short-time Fourier transform in traditional signal processing. Bearing in mind the rapidly increasing amounts of data and large dimensions of graphs related to practical applications, the calculation complexity of each tool for the spectral analysis of signals on graphs shall be continuously revisited. As they provide the possibility to calculate VF representations using only local neighborhoods of vertices, without the need for the eigendecomposition, polynomial approximations of spectral windows are commonly used in practice, mostly in the form of the Chebychev approximation. This paper revisits this choice, compares it with two other polynomial approximation approaches, and investigates their influence on the VF-based graph signal analysis and inversion.","PeriodicalId":220339,"journal":{"name":"2020 24th International Conference on Information Technology (IT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931162","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 work, a recent DNR mathematical algorithm based on the graphical representation of the distribution system connections is employed to optimally allocate distributed generations (DGs) along with DNR, simultaneously. In this context, DGs based smart inverters are the used DG types. Case studies are conducted on the 83-node practical distribution system. The merits of this work are to improve loss minimization and enhance its voltage stability. A recent metaheuristic optimization algorithm is employed to solve the proposed mixed-integer nonlinear programming problem (MINLP) called Harris Hawks Optimization (HHO) algorithm. The proposed optimization approach succeeded in minimizing the total active losses by 21.428%.","PeriodicalId":220339,"journal":{"name":"2020 24th International Conference on Information Technology (IT)","volume":"143 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133111870","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}

It has been shown that the neural network can be employed to accurately model the relationship between the photovoltaic panel current, voltage, solar irradiance, and temperature. Unlike the equivalent circuit model, the neural network model can be used to calculate the gradient of the P-V curve, thus enabling the design of the simple MPPT technique that relies on the steepest ascent method. Simulation results show that the proposed algorithm exhibits a faster convergence speed and a smaller steady-state error than the conventional P&O algorithm.","PeriodicalId":220339,"journal":{"name":"2020 24th International Conference on Information Technology (IT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133759116","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}

Nonstationary fuzzy system, which aims to model the type-2 fuzzy sets with a number of type-1 sets -obtained with the help of perturbation function- is one of these methods. In this study, the type-1 fuzzy subsets which are used in nonstationary systems are optimized by the help of the genetic algorithms. Thanks to the convergence rate of the genetic algorithm, the obtained type-1 fuzzy subsystems are close to the best solution. So, the nonstationary fuzzy set which is generated using the genetic algorithm gives us a better solution instead of the nonstationary fuzzy sets created by perturbation functions which are based on mostly randomness. The success of the obtained nonstationary fuzz set is proven by the simulation results.","PeriodicalId":220339,"journal":{"name":"2020 24th International Conference on Information Technology (IT)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127285020","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}
