Based on this data, it chooses the team's influence zones, passing options, and what-if scenarios. An interdisciplinary field known as computer science in sport aims to combine the theoretical as well as practical elements and approaches from the fields of informatics and sport science. The use and usage of computer-based but also mathematical methodologies in sport science is where interdisciplinary is most heavily weighted, with the goal of advancing both theory and practice in sports. It is mainly due to the established fact that the use of information and media, the planning of models, the analysis of systems, etc. increasingly demands the backing of relevant tools and ideas which are developed and available in technology. Football is one sport where computer science in sports is a rapidly expanding topic in our culture. Football match analysis is unquestionably a crucial responsibility for coaches, teams, players, and even sports fans. Thanks to modern technologies, more and more match data can be quickly collected and evaluated. Football associations are now able to assess, enhance, and protect players' officiating because to advancements. On devices provided by the league, coaches and football officials can analyse opponents' offense and defence as the game progresses. Football computer science has enhanced player and group performance. It is vital to conduct some background research on each football-related problem in order to have a better knowledge of the conditions that led different regulatory bodies to reach such challenging conclusions. In more than a century of football, many fans have witnessed numerous significant errors committed by the officials on the field that resulted in crushing defeats for their favourite teams. Examples include poor handball, offside, and foul calls, to name a few.Tétel Korlátozottan hozzáférhető A recipe finding web applicationAgbese, Gabriel; Vágner, Anikó; DE--Informatikai KarThe application is designed to be easy to use, with a simple interface that allows users to input their available ingredients.

This thesis investigates the potential for enhanced autonomous driving accuracy by combining sensors and AI algorithms. All algorithms and other tests for the thesis were performed on a model vehicle. And I mainly verify lane recognition and obstacle detection. The obstacle and lane are recognized by the camera after deep learning, then the car will changing lane to obstacle avoidance. To enhance the efficacy of obstacle avoidance of model vehicles, the advantages and drawbacks of various image recognition and obstacle avoidance algorithms are also discussed in this paper. At the same time, the combination of the use of LIDAR can better fill the shortage of image recognition. Ultimately we propose that the data from the sensors can be processed with different connectivity layers, and that hybrid deep learning can be used to improve the accuracy of autonomous vehicle driving for obstacle avoidance.Tétel Korlátozottan hozzáférhető Stochastic Algorithm Case StudyZhang, Su Ying; Baran, Sándor; DE--Informatikai KarGlobal and constrained optimization problems nowadays appear in almost all fields of science and engineering.
