Preface

Abstract

4th International Conference on Applied Physics, Simulation and Computing(APSAC 2020)This volume is from proceedings of the 4th International Conference on Applied Physics, Simulation and Computers. The conference focus was in the areas of applied physics, simulation and computers and was held May 23-25, 2020, in Rome, Italy. The scope of the conference was to provide a forum for physicists and applied mathematicians as well as for engineers to present new analytical methods, new simulation methods and mathematical models in their disciplines. The book is divided into four sections that focus on different topics, with the first section focusing on applied physics, the second focusing on simulation, the third focusing on computing and the forth focusing on acoustics. All chapters are self-contained and peer-reviewed.Due to the COVID-19 virus and travel restrictions, the 4th International Conference on Applied Physics, System Science and Computers was held online using video conferencing tool. This online conference was attended by 42 participants, who were from Austria, United Kingdom, Czech Republic, Italy, Poland, Russia, Spain, Argentina, Latvia, Lithuania, Ukraine and other countries. The organizers coordinated the presentations from Rome, Italy and every speaker had 30 minutes for the online presentation. This online remarkable event allowed the communication of professors, researchers, scholars and students in the field of Applied Physics, Simulation and Computing making the conference a perfect platform to share experience, foster collaborations across industry and academia, and evaluate emerging technologies across the globe.The EditorsProf. Badea Lepadatescu, Transylvania University of Brasov, Brasov, Romania Prof. Claudio Guarnaccia, University of Salerno, Salerno, Italy
