Thus, the choice of optimal cutting parameters (cutting speed, feed and depth of cut) is very important in order to ensure a better surface condition of the machined parts and the life of the cutting tools, which requires great relationship with the wear of the tool-part interface. The result of a good choice of cutting conditions can be seen by a reduction in this wear. During machining, the geometric shape and the physical state of the tool are modified by the combined action of the cutting forces and by the temperature reached by the cutting edge. These modifications which gradually increase with the duration of machining are commonly grouped under the term wear of the tool. They appear on the active part of the tool. In this work, we propose an optimization method allowing determining a mathematical model of the wear and tear by applying the experiment plan. This model highlights the relationship between the elements of the cutting regime (cutting speed, feed and depth of passes) and the responses studied (Wear in clearance).","PeriodicalId":39336,"journal":{"name":"International Journal of Energy, Environment and Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86306421","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}

Currently, the world is highly dependent on fossil fuels for energy needs, and these fossil fuels are on the brink of extinction. Demand for renewable energy will increase sharply in the coming years. Our work presents a hybrid system of energy generation with photovoltaic and wind system. Wind and PV system is connected to the grid as well as with each other. A control strategy is designed to maximize the benefits of such network interface system. The inverter is programmed to work as a multi-functional device with active power filtering capabilities. As a result the inverter is employed to power the RES energy in the network as a power converter. All analysis is performed and validated by the MATLAB / Simulink simulation, placing the system under dynamic load conditions.","PeriodicalId":39336,"journal":{"name":"International Journal of Energy, Environment and Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85818187","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 discuss some design aspects concerning the optimal proportion between the two means of education applied to Engineering students. Our approach is taking into account the creative potential of engineering students and their type of thinking that have been previously investigated through the Brain Lateralization Information System (BLIS) [1]. In this paper we aim at identifying ways in which creative thinking and problem solving techniques can be implemented as personalized Blended Education Programs for students attending courses in the fields of Engineering. A blended course has an integrated online component and a concomitant face-to-face seat time, in order to reach student populations that cannot attend a fully face-to-face program. The advantages of face to face and the advantages of online activities have been put into balance and discussed. The purposes behind learning activities should be expressed by: community building, trust building, spontaneous reaction, clarification on one hand and reflection, analysis, exploration, creation on the other hand. In our efforts of designing a blended course we have considered the best suited modality for each specialty.","PeriodicalId":39336,"journal":{"name":"International Journal of Energy, Environment and Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77583159","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 shown that it is not possible to rank in one part Asian countries and in second part European countries. It is better to rank Asian and European countries together because they represent the same level of development in one hand and the emerging countries in the other.
