Preface

György Molnár
2021 Acta Polytechnica Hungarica  
We are pleased to present our second special issue dedicated to a CogInfoCom theme to our readers. Our first thematic volume published at the beginning of 2020 contained the best studies and presentations from the proceedings of the 2018 conference. The present CogInfoCom-themed issue matches the thematic outlay of the previous CogInfoCom conference held in 2019. We hope that this periodical will help readers to learn about several professional research developments leading to further consideration of the given topics.
