Some interoperability proposals are intended to use metamodels, models, and frameworks, in which visual representations are included. However, such proposals describe interoperability according to their point of view, focus of analysis, solution techniques, and specific level of interoperability; in addition, some of the visual representations use no standards, which lead to subjective interpretations by the reader. In this paper we propose a representation formalizing interoperability which includes essential elements and structural relationships among them. After a review of previous work, a summary of the analyzed literature is performed by using linguistic analysis in order to recognize the relationships among interoperability essential elements and mapping them to controlled language expressions. Finally, the mapping process is used to represent the interoperability essential elements and their relationships by using pre-conceptual schemas linked to the definition of each essential element. As a result, a pre-conceptual schema of the software system interoperability is proposed. Such a pre-conceptual schema is also used for explaining an interoperability lab study adapted from the literature. The proposed pre-conceptual schema explains the interoperability between two software systems and allows for characterizing interoperability problems and solutions.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90708398","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}

This type of data is a part of the symbolic data. There are many cases such as colors in image learning where histogram-valued data are naturally found. This study focuses on classification of the histogram-valued data by extending two approaches of support vector machine (SVM), namely, the expected-based and quantile-based probabilistic SVM on histogram-valued data. In both approaches, the cases of linear and nonlinear problems as well as the least-square classification are discussed. In addition, the extension to multi-class classification is also discussed. To compare the performance of the proposed procedures a simulation study has been done based on some generated data sets. The data are generated from various distributions with various parameters to represent different cases of classification, including binary and multi-class classification. Further, the methods are applied on two different real data sets. From the results, it can be concluded that our proposed methods perform well on wide range of classification problems.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78990991","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, power loss reduction is one of the important mission in operation the DN. This paper presents a method of simultaneous execution of network reconfiguration (REC) and distributed generation placement (DGP) based on a new swarm intelligent (SI) namely wild geese algorithm (WGA) to reduce power loss considering the improvement of voltage and current profiles as well as satisfy the constraints including radial topology, distributed generation capacity limit and power balance. The efficiency of the proposed WGA is evaluated on the 33-node and 69-node systems at two cases of REC and REC-DGP. The performance of WGA is contrasted with two SI-based methods including well-known particle swarm optimization (PSO) and recent developed pathfinder algorithm (PFA). The obtained results demonstrate that REC and REC-DGP are effective solutions to reduce power loss and improve voltage and current profiles of the DN, wherein REC-DGP achieves higher efficiency than REC. Furthermore, the statistical results show that WGA outperforms PSO and PFA for both problems in indexes of worst, average, standard deviation values of the fitness function and the computation time. The contrasted results with the previous performed methods also point that WGA can reach the better results than other ones for the REC and REC-DGP problems. Thus, WGA can be a potential method for the RECDGP problem.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81878761","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 software was developed by SNSU-BSN to control the calibrator and DMM using the GPIB interface. The key advantages of this development were that the software could be used easily, safely, and fast with high accuracy and precision. The developed software has been validated by comparing it to manual measurement. The type A uncertainties achieved by semi-automatic measurement were less than 0.1 μV/V for dc voltage, 0.2 μA/A for dc current, 2 μV/V for ac voltage at 1 kHz, 100 μA/A for ac current at 1 kHz, and 0.1 μΩ/Ω for resistance with each absolute normalized error of the comparison was less than 1. It showed that both the manual and semi-automatic measurements had a good agreement in each measurement, and also the evaluated type A uncertainty in the semi-automatic measurement was smaller than the manual measurement.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81426585","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 developed analytical algorithm investigates the air gap length at the maximum and minimum inductances. These are achieved through the machine rotor pole arc, stator pole arc, bore diameter, back iron thickness, rotor yoke thickness, stack length, and rotor pole diameter. The validity of the newly developed analytical procedures for predicting the maximum and minimum inductances was evaluated using the measurements obtained from the machine prototype. There was a good correlation between the analytical and experimental results. Inductances and air gap lengths of 2/2 DSRM of equal stator and rotor pole width and stator pole width greater than the rotor pole width were investigated and analyzed using the developed algorithm. A second existing DSRM with different numbers of stator and rotor poles whose inductances have been known and compared with finite element analysis (FEA) is chosen to verify the algorithm developed. The 2/2 DSRM’s potential to sustain oscillation during energy conversion from mechanical energy to electrical energy is investigated.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73868549","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}

Optimal power flow (OPF) is a static nonlinear programming issue which enhances a specific target work while fulfilling a lot of physical and operational imperatives forced by gear confinements and security/voltage dependability requirements. Flexible AC transmission systems (FACTS) apparatus are coordinated in power frameworks for controlling force stream to enhance the execution of the power frameworks under both ordinary activity and system contingency. This paper presents a new algorithm named Modified Adaptive Differential Evaluation to limit the generator fuel cost in ideal power stream control with Flexible AC Transmission systems and voltage soundness constraints. The FACTS apparatus considered here incorporate static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC). The proposed methodology has been inspected and tried on the IEEE 30-bus test network. A few cases were explored to test and approve the power of the proposed strategy in finding the ideal arrangements under both ordinary activity and chose system possibility conditions. Test results show that the proposed methodology can get better arrangement and requires less CPU time than the calculations announced in the writing.","PeriodicalId":38705,"journal":{"name":"International Journal on Electrical Engineering and Informatics","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89033385","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}
