Some Economic Characteristics of Internet Platforms
Authors: Plavčan Peter , Funta Rastislav 
Published: October 2021

Abstract
Various internet platforms have rapidly developed into central points of everyday life, for private individuals as well as for companies (often dominated by a single or a few companies). At the same time these internet platforms are advancing into more and more areas of business. This creates the risk of dependency, abuse of power, manipulation, concentration of power, centralization of data and information with corresponding effects on technological development, innovation, economy, society and politics. From an economic point of view, this article examines how the strong market positions of internet platforms arise and can be maintained. The dynamics of these technology and innovation-driven markets and the differences from conventional markets are also discussed. These internet markets have emerged from a series of innovations and are characterized by rapid technological development. Taking into account the economic peculiarities as well as knowledge from innovation and governance research, recommendations are drawn up on how these problems can be dealt with.

Online interaction of Olympic volunteers after the Games
Authors: Sukharkova M. P. 
Published: October 2021

The article is devoted to the community of Olympic volunteers after the event through the study of their online activity in social network “Vkontakte”. Olympic volunteering refers to the event-oriented direction of volunteering, which is characterized by a limited period of time for the implementation of volunteering practices, but a long period of training volunteers and the opportunity for volunteers to acquire unique work experience during the organization and holding of a major sports event. At the moment, there is a lack of research on the impact of events such as the Olympic and Paralympic Games on the volunteer community.The legacy of the 2014 Olympic and Paralympic Games for the volunteer community is studied in the article. In the course of the study, an attempt was made to find answers to the following research questions: do volunteers maintain social online interactions five or more years after the event; if volunteers continue online interactions, what topics are the most popular for discussion in the volunteer community. It is proved that volunteering at major sporting events contributes to the development of the social capital of volunteers, including by expanding the circle of acquaintances, that is, social interactions. At the same time, social networks have a great influence on the reproduction of social capital, so the indicators of online interactions of volunteers can indicate whether the volunteers support the circles of social interactions acquired while working at the games, and, thus, whether the volunteers support and use the social capital acquired while working at the event. During the entire period of time considered by us, the highest indicators of volunteer activity in the online community were noted from 2014 to 2016. The most relevant topics among the participants of the online community are the topics of volunteering: both memories of working at the games, as well as information about other volunteer programs and other topics, for example, tourism, etc.

Published: October 2021

ABSTRAKKendali formasi adalah topik penelitian kendali multi-robot, dimana sekelompok robot dapat mencapai formasi tertentu dan mempertahankannya ketika berpindah ke arah yang diinginkan. Salah satu pengembangan kendali formasi adalah kendali formasi berdasarkan jarak dimana setiap individu robot menggunakan informasi jarak antara sesamanya untuk mencapai tujuan formasi. Banyak pengembangan yang dilakukan pada kendali formasi berdasarkan jarak menggunakan model yang sederhana dan membutuhkan pengembangan lebih lanjut untuk penerapan kendali ke model yang lebih nyata. Ketika penerapan kendali formasi berdasarkan jarak, terdapat permasalahan kondisi awal yaitu robot tidak dapat menentukan koordinat tetangganya. Penelitian ini akan mengembangkan algoritma cosinus sebagai solusi untuk kondisi awal kendali formasi berdasarkan jarak. Algoritma cosinus terinspirasi dari rumus segitiga sederhana dan mengharuskan robot melakukan dua langkah saja untuk dapat menemukan koordinat tetangganya. Hasil percobaan simulasi, kendali formasi berdasarkan jarak menggunakan tiga model robot holonomic dan penerapan algoritma cosinus membutuhkan waktu rata-rata 6.5 detik untuk menemukan koordinat tetangganya.Kata kunci: Kendali Formasi, Multi-Robot, Algoritma Cosinus, Mobile Robot. ABSTRACTFormation control is a research topic of multi-robot control, where a group of robots can reach a certain formation and defend it when moving in the desired direction. One of the developments is distance-based where formation goals achieved using the distance between each other only. Many developments are using a simple model and need further development into a realistic model. When applying distance-based, there is a problem in the initial condition, namely that the robot cannot find the coordinates of its neighbors when using only distance. In this work, the cosine algorithm was developed as a solution to the initial conditions which are inspired by a simple triangle formula and need only two steps to find the coordinates. From simulation experiment results, distance-based formation control using three holonomic robot models and the application of the cosine algorithm takes an average of 6.5 seconds to find the coordinates of its neighbors.Keywords: Formation Control, Multi-robot, Cosine Algorithm, Mobile Robot.

ABSTRAKMakalah ini memberikan analisis perbandingan antara teknik kendali klasik yaitu kendali PID dengan teknik kendali modern pada sistem Eddy current brakes dinamometer. Eddy current brakes merupakan sistem pengereman modern yang membutuhkan sebuah sistem kendali untuk menunjang kinerja pengereman. Selama ini kendali PID lebih sering digunakan, namun di beberapa kondisi dinilai kurang optimal. Dengan demikian, diperlukan pengembangan kendali yang modern dan optimal yaitu full state feedback Linear Quadratic Regulator (LQR). Perbandingan respon waktu pengereman disimulasikan menggunakan Matlab/Simulink. Hasil simulasi menunjukkan respon waktu pengereman pada kendali LQR lebih baik dibandingkan dengan kendali PID, dengan Ts = 2.12 detik, Tr = 1.18 detik, dan tanpa overshoot. Adapun kendali PID, meskipun menghasilkan Ts = 0.27 detik dan Tr = 0.18 detik, namun demikian masih terdapat overshoot sebesar 0.7%.Kata kunci: Eddy brakes, PID, LQR, Matlab ABSTRACTThis paper provides a comparative analysis between PID control as a classical control technique and modern control technique in the dinamometer Eddy current brakes system. Eddy current brakes is a modern braking system that requires a control system to support the braking performance. PID control is often used to be implemented but in some conditions it is less optimal. Therefore, it is necessary to develop a modern and optimal control, such as a full state feedback Linear Quadratic Regulator (LQR). The comparison of the braking time responses were simulated using Matlab/Simulink. The simulation results show that the response of LQR control is better than the PID, with Ts = 2.12 seconds, Tr = 1.18 seconds, and without overshoot. On the other side, PID control, although having Ts = 0.27 seconds and Tr = 0.18 seconds, there is still an overshoot about 0.7%.Keywords: Eddy brakes, PID, LQR, Matlab
