The article presents the possibility of conducting remote laboratory classes in subjects that require the use of specialized equipment (which the student does not have at home). The article is based on the example of classes in microcontrollers programming and electronic circuits. The methods with the use of simulation programs and an innovative approach enabling work on real equipment are presented. The solutions presented in the article were practically and successfully implemented in connection with the coronavirus pandemic in spring 2020 at the Faculty of Electrical Engineering of West Pomeranian University of Technology in Szczecin. A very important feature of the presented ideas is the possibility to adapt the already existing stationary solutions to remote work and use free applications. The characteristic feature of the presented ideas is also simplicity. These two features make it possible to implement remote learning quickly and at a low-cost. Classes conducted using the described system for a group of about 50 students were positively evaluated by them. Their opinions were also included in the article.

3D Digitisation

In the era of the global pandemic caused by the COVID-19 virus, 3D digitisation of selected museum artefacts is becoming more and more frequent practice, but the vast majority is performed by specialised teams. The paper presents the results of comparative studies of 3D digital models of the same museum artefacts from the Silk Road area generated by two completely different technologies: Structure from Motion (SfM)—a method belonging to the so-called low-cost technologies—and by Structured-light 3D Scanning (3D SLS). Moreover, procedural differences in data acquisition and their processing to generate three-dimensional models are presented. Models built using a point cloud were created from data collected in the Afrasiyab museum in Samarkand (Uzbekistan) during “The 1st Scientific Expedition of the Lublin University of Technology to Central Asia” in 2017. Photos for creating 3D models in SfM technology were taken during a virtual expedition carried out under the “3D Digital Silk Road” program in 2021. The obtained results show that the quality of the 3D models generated with SfM differs from the models from the technology (3D SLS), but they may be placed in the galleries of the vitrual museum. The obtained models from SfM do not have information about their size, which means that they are not fully suitable for archiving purposes of cultural heritage, unlike the models from SLS.

The Rich

Among the rich and diverse scientific activities conducted by Henryk Cioch, foundation law occupies a special place. This subject matter became the focus of the Professor’s interest since the Law on Foundations came into force. A characteristic feature of his work was a critical and innovative approach to statutory provisions regulating the functioning of the foundation. The whole scientific output of Henryk Cioch allows us to conclude that he postulated the need for a reform of foundation law. The purpose of this article is to analyse the views expressed by Henryk Cioch on the necessity to make the necessary amendments to the existing text of the Law on Foundations. It is, first of all, an indication of those de lege ferenda postulates put forward by the Professor, which have been included either in the hitherto amendments to the Law on Foundations or reflected in the case-law. The analysis contained in this article will focus on the key problems of foundation law, which according to Henryk Cioch were: the concept and types of foundations, the establishment of foundations, the system of foundations and supervision over their activities, transformation and abolition of foundations.

The Impact

We are glad to introduce you that the 2021 4th International Conference on Mechanical, Electrical and Material Application (MEMA 2021) was successfully held on October 29-31, 2021. In light of worldwide travel restriction and the impact of COVID-19, MEMA 2021 was carried out in the form of virtual conference to avoid personnel gatherings. Because most participants were still highly enthusiastic about participating in this conference, we chose to carry out MEMA 2021 via online platform according to the original schedule instead of postponing it. MEMA 2021 is to bring together innovative academics and industrial experts in the field of Mechanical, Electrical and Material Application to a common forum. The primary goal of the conference is to promote research and developmental activities in Mechanical, Electrical and Material Application and another goal is to promote scientific information interchange between researchers, developers, engineers, students, and practitioners working all around the world. The conference will be held every year to make it an ideal platform for people to share views and experiences in Mechanical, Electrical and Material Application and related areas. We were greatly honored to invited Prof. Kun Li, from Chongqing University, China and Assoc. Prof. Wei Wei, from Xi’an University of Technology, China as our Conference Chairmen. This scientific event brings together more than 100 national and international researchers in mechanical, electrical and material application. During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. We were pleased to invite four distinguished experts to present their insightful speeches. Our first keynote speaker, Prof. Shahid Hussain, Jiangsu University, China. His research interests include MOS-MOF-MXene Nanomaterials, Gas-Sensors, Electrochemical Supercapacitors, Li-S batteries. And then we had Prof. Jie Huang, from Southwest University, China. His research includes RF/Microwave circuits and sensors. Prof. Qiyan Xu, Anhui University of Technology, China. His main research directions are: New process and technology of low cost steel making, Direct reduction and melting reduction, Development of new metallurgical technology - comprehensive utilization of waste resources. Lastly, we were glad to invite Prof. Kun Li, Chongqing University, China. He mainly engaged in additive manufacturing, intelligent 3D net forming, high performance materials and phase transformation, material computing and other research. In the last part of the conference, all participants were invited to join in a WeChat group to discuss and explore the academic issues after the presentations. The online discussion was lasted for about 30-60 minutes. We are glad to share with you that we still received lots of submissions from the conference during this special period. Hence, we selected a bunch of high-quality papers and compiled them into the proceedings after rigorously reviewed them. These papers feature following topics but are not limited to: Mechanical Dynamics and its Applications, Material Physics, Electrical and Electronic Systems and other related topics. All the papers have been through rigorous review and process to meet the requirements of International publication standard. Lastly, we would like to express our sincere gratitude to the Chairman, the distinguished keynote speakers, as well as all the participants. We also want to thank the publisher for publishing the proceedings. May the readers could enjoy the gain some valuable knowledge from the proceedings. We are expecting more and more experts and scholars from all over the world to join this international event next year. The Committee of MEMA 2021 List of Committee member is available in this pdf.

The VISIR+ project was an international collaboration project for the dissemination of the remote laboratory VISIR, a tool to support teaching the theory and practice of electrical and electronic circuits. The initiative was first disseminated in Europe, and Latin American countries such as Brazil followed. This chapter essentially aims to discuss the experience of the Federal University of Santa Catarina in Brazil with the VISIR+ project. Various approaches were used for the dissemination of the initiative, including free courses for high school students, teacher training, and the creation of a virtual environment to discuss and share lesson plans that used the remote laboratory VISIR on their plots. In conclusion, the experience was observed as excellent for the institution and there was no reason to put the project ideas aside. After participating in the project, it becomes a challenge to ensure its sustainability.

Different Levels

We develop a simple theoretical framework for thinking about how geographic frictions, and in particular travel costs, shape scientists’ collaboration decisions and the types of projects that are developed locally versus over distance. We then take advantage of a quasi-experiment—the introduction of new routes by a low-cost airline—to test the predictions of the theory. Results show that travel costs constitute an important friction to collaboration: after a low-cost airline enters, the number of collaborations increases between 0.3 and 1.1 times, a result that is robust to multiple falsification tests and causal in nature. The reduction in geographic frictions is particularly beneficial for high-quality scientists that are otherwise embedded in worse local environments. Consistent with the theory, lower travel costs also endogenously change the types of projects scientists engage in at different levels of distance. After the shock, we observe an increase in higher-quality and novel projects, as well as projects that take advantage of complementary knowledge and skills between subfields, and that rely on specialized equipment. We test the generalizability of our findings from chemistry to a broader data set of scientific publications and to a different field where specialized equipment is less likely to be relevant, mathematics. Last, we discuss implications for the formation of collaborative research and development teams over distance. This paper was accepted by Toby Stuart, entrepreneurship and innovation.
