'Les Perses de l'Occident' de Sotiris Skipis: Une invasion barbare en Europe dans les années 1920
No full textThe study examines the contribution of Sotiris Skipis (1881-1952) to theatrical art, an aspect which has been neglected by contemporary research. It focuses on an almost unknown three-act drama of Skipis, which the present research retrieved from the rare collections of Greek libraries: Les Perses de l' Occident (The Persians of the West). The author published the work in Paris in 1917, before the bloodshed of World War I was beginning to wane, to openly condemn pan-Germanism and racism, even before the latter term prevailed. The paper explores the ideological, aesthetic, and dramaturgical substratum of the text reflecting the spread of racial theories in Europe is explored. It also interprets the reasons that did not allow for the stage realization of the play on Parisian stages at the time of publication, despite the warm praise from Parisian scholarship, and that it took more than a century to pull the play out of oblivion

The paper examines the role of metacognition and its impact on the learning process, as well as the use of digital technologies such as remote labs, virtual labs, augmented reality, virtual reality, and mobile devices in STEM education. Results from this research suggest that the use of these digital technologies can be beneficial for science learning in both higher and secondary education. Additionally, these technologies can be used to promote student engagement, collaboration, and access to scientific knowledge. Furthermore, metacognition is an important skill for both teachers and students, and can be developed through the use of the knowledge pyramid, emotional intelligence pyramid, metacognitive pyramid, and giftedness pyramid models.Este artigo investiga as tendências atuais na transformação de laboratórios STEM na era da digitalização devido à integração de tecnologias digitais e ao reconhecimento da importância do desenvolvimento de habilidades metacognitivas.

Control of a DC Microgrid
No full textThe growth of distributed Renewable Energy share in the total electricity production as wells as technological advancements in power electronics and increase of DC loads, point towards the development of the DC microgrid (DCMG) concept as a valid model for future energy systems especially for operations and locations where the existing grid cannot satisfy.A DC microgrid consist of distributed sources, load and storage connected to a DC bus through converters. The two main issues in a DCMG operation is the power balance between supply and demand and its implementation through the interfacing converters, who in turn must be able to facilitate these operations. Many grid control strategies can be used but whatever the strategy may be, control is achieved through regulation of the DC bus voltage.In this thesis a decentralized primary controller is selected, analyzed and modelled for power balance operations in an islanded 48V-LVDC microgrid, consisting of a renewable energy source, an electronic load and storage capability. Control is achieved through dc bus voltage monitoring and control operations on the interfacing converters, based on predefined voltage set points. As an interfacing converter, a cascaded half bridge buck and boost converter is used and controlled. Two different control modes are implemented: buck operation for the start-up of the grid and a special constant frequency modulation for soft switching and increased efficiency of the converter.Furthermore, its use as multi-purpose converter, its low level control schemes and the co-operation with the high-grid level control are studied. Physical switching models are used to account for the real operation of the converter, when operating under higher level control, aiming at grid stability and optimal power flow.Electrical Engineering | Sustainable Energy Technolog

Metal Forming Process Efficiency Improvement Based on AI Services
No full textPublisher Copyright: © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.In this work, the application of Artificial Intelligence (AI) and Machine Learning (ML) techniques in the field of metal forming processes in Shear Forming and Spinning machines are explored. The main objective is to improve the quality of the parts produced and the efficiency of these processes through the implementation of predictive models and online value-added services. Firstly, different methods for the analysis and evaluation of the quality of manufactured parts are presented. Additionally, predictive models for online failure detection are developed, based on historical and real-time data, which helps prevent failures and reduce production costs. Furthermore, the challenge of detecting changes in the input material, which can have a significant impact on process outcomes, is addressed. Lastly, the implementation of an algorithm towards “zero defects” is proposed to achieve optimal conditions in the metal forming process. The described approaches enable customers of the incremental forming machine manufacturer to access a diverse range of services associated with the implemented methods. ...Peer reviewe
Rebels with a Cause: The December 2008 Greek Youth Movement as the Condensation of Deeper Social and Political Contradictions
No full textThe events of December 2008 in Greece represent a turning point in social movements against neoliberalism and capitalist restructuring. They were the result of worsening employment prospects for young people, the aggressive restructuring of the educational system and concern about the effects of the current economic crisis. The originality of the movement lies in its unique scale, in the expression of a new unity of youth in struggle, in the demand for radical change and in its anti-systemic character. It can be viewed as further evidence of the crisis of neoliberal hegemony and as a sign of growing hegemonic instability in European capitalist social formations. For this reason it poses both a theoretical and a political challenge. Copyright (c) 2010 The Author. Journal Compilation (c) 2010 Joint Editors and Blackwell Publishing Ltd.
