ABSTRACT
The last two years and the COVID-19 situation showed the need to ensure sustainable engineering education via the use of virtual and remote laboratories. The aim of the article is to design a laboratory model for studying the characteristics of DC electric motors. The implementation is based on different well know solutions, such as Raspberry PI, ESP32, power modules and sensor. The communication is based on the TCP/IP protocol and the control of the power modules is implemented using PWM. The IoT implementation of the lab is based on the Home Assistant platform, which allows monitoring and control of remote devices. The study also presents the schematic diagram of the virtual laboratory system, which allows to explain and substantiate the role and behavior of each component. © 2022 IEEE.
ABSTRACT
Being challenged by the COVID-19 pandemic, innovative educational solutions are needed to provide global educational experiences to undergraduate students. In Summer 2020, a US-Peru collaborative effort was conducted using virtual platforms to deliver a Sustainable Engineering and Leadership Practices (SELP) program. In previous years, the SELP program included face-to-face sessions with interactive technical, cultural, and social activities. The SELP program focuses on engineering and management challenges to address societal needs. The technical sessions cover sustainability principles and engineering practices following a problem-based solution approach. Emphasis is placed on the importance to communicate the short, medium, and long-term consequences of engineering solutions to decision-makers and society. Practical real-world examples are presented to illustrate the concepts learned in the course. The cultural activities include visits to museums and local heritage sites while the social activities involve cuisine, sports, and local attractions. With the participation of thirty students in a virtual environment, binational teams were assembled and developed projects to address sustainability problems affecting their communities. This paper summarizes the lessons learned and what led to a successful well-rounded educational experience with virtual technical, cultural, and social interactive sessions. © American Society for Engineering Education, 2021
ABSTRACT
The Virtual Special Issue (VSI) "New research on reduction and/or elimination of hazardous substances in the design, manufacture and application of chemical products" was initially associated to the "International Conference on Green Chemistry and Sustainable Engineering, GreenChem-20" that was postponed due to the COVID-19 pandemic. Anyway, the international conference will take place in the near future. However, the VSI was maintained in this journal, received a high number of submissions, and selected manuscripts have been accepted after peer-reviewing. The published papers constitute a set of high-quality contributions, which, in the future, could be complemented with others related to additional conferences about similar topics. In this editorial piece, the Editors include brief comments on papers accepted for publication in the Special Issue, as well as additional aspects of interest related to the subject.
