Provision of power quality improvement such as Harmonic Reduction is the basic key to obtain higher utilization of wind energy. This functionality for future systems leads to lower energy cost, and reliable power system. To incorporate the advanced features, a five level cascaded H – bridge inverter, with reduced number of power electronic switches is progressed in this study, that is configured within the renewable source systems such as solar and wind. The study is carried out on a 10 KW PMSG based wind energy conversion system interfaced to grid. The proposed concept is elucidated through modelling, simulating and analysing in MATLAB/Simulink environment.","PeriodicalId":391912,"journal":{"name":"The International Journal of Electrical Engineering & Education","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123080127","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 was found that the core competencies of EECS students clearly defined the direction of the students’ development especially mathematics ability, scientific and engineering knowledge, implementation, design and analysis, self-study, communication, social development and ethics with high degrees of overlap. This also means that, in addition to mathematical logic, EECS students should also have knowledge related to engineering science, implementation ability, communication and cooperation, and social networking ability. Finally, recommendations for cultivating the core competencies of EECS students were proposed in the hope that graduates will acquire the core competencies required by the industry.","PeriodicalId":391912,"journal":{"name":"The International Journal of Electrical Engineering & Education","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132355648","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}

Resultant wave-shapes may not be accurate and determined values of different parameters may not be exact. Due to inaccurate outcomes and time-consuming process in a conventional way, researchers despond to continue their approach. In this paper, a trainer kit has been developed which is just like a laboratory with necessary components and aims to implement multivibrators (Bistable, Monostable, and Astable) and RC phase shift oscillators in the laboratory. A variable power supply is constructed in the trainer kit that provides 9 V dc to the multivibrators and 15 V dc to the oscillator. Potentiometer, voltage regulator, different active and passive components such as resistors, capacitor, op-amp, transistor, and numerous jumper wires are introduced in this kit. The trainer kit ascertains an easy implementation by eliminating complexity and assures accurate wave-shapes at the oscilloscope within a short time. To validate the proposed system, a survey program has been introduced among many students and faculty members. The outcome of the survey is the demonstration of student and instructor views and opinions which acknowledges the trainer kit as an efficient and compatible working platform.","PeriodicalId":391912,"journal":{"name":"The International Journal of Electrical Engineering & Education","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133302327","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}

Building Information Modeling (BIM) technology has been widely used in the development of the construction industry in recent years. It can effectively realize the integration of building information, so that all parties involved in the project can work together based on the same platform, which can more effectively improve work efficiency and save resource input, lower construction costs, and ultimately achieve the goal of sustainable development.

This paper aims to explore the psychosocial path of people participating in the collective action of NIMBY conflict, and to provide theoretical basis for effective governance of NIMBY conflict. By integrating the psychosocial explanatory variables related to collective action, we construct a regulated double mediation Model, which is empirically tested with 566 questionnaires from the NIMBY conflict in gaoling, China. The results show that: group relative deprivation, group emotions and group effectiveness have positive effects on people's NIMBY conflict participation tendency; group effectiveness and group emotions are important mediating variables of group relative deprivation affecting people's NIMBY conflict participation tendency; group identity has a positive adjustment effect on people's group emotions, group effectiveness, and the participation tendency of NIMBY conflict. The research indicates that group relative deprivation is the key precursor of NIMBY conflict, group emotion is the key factor driving the deterioration of NIMBY conflict, and group identity is the key factor catalyzing the occurrence of NIMBY conflict. This study helps to explain the psychological mechanism of people's participation in NIMBY conflict, and has certain implications for the prevention and governance of NIMBY conflict.","PeriodicalId":391912,"journal":{"name":"The International Journal of Electrical Engineering & Education","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114822424","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}

Therefore, the great difference in lifestyles could cause culture shock, which make tourists’ trip a relative awful experience, especially in the popular resorts of some countries such as Europe and America, where tips are given whenever there is a service being provided, and this behaviour confused lots of tourists from Asia, Africa or even European countries. Based on decision tree, this study aimed to share troubles of those tourists with needs by taking the New York City Taxi and Limousine Commission’s database as research’s target, thereby analysing factors that may cause variation in tipping rates. Finally, it is found that distance and duration contributed most to trip fare. Also, besides accurately predicting the tip amount, how each factor contributes to the trip needs to be known; thus, linear regression is used to check the validity of the result, and a 14.1% rate of all distance as a fee is achieved.

In the meantime, according to the theoretical basis and the characteristics of VR, a set of general models of VR gesture interaction is designed, the factors affecting the efficiency of VR gesture interaction are studied, and reasonable interaction feedback is designed. By using the computer vision and image processing technology, gesture-based interaction can collect natural gestures, extract gesture features, recognize gesture indications, and respond to the user demands.

The research results show that the application of gesture feature design method in the game can analyze the factors affecting the interaction efficiency.
