This book gathers papers that are centered on the theory and practice of a wide variety of advanced technologies. They cover the latest developments in computing, networking, information technology, robotics, complex systems, communications, energy, mechanical engineering, civil engineering, geodesy, and other subjects. These papers were selected for presentation at the 12thannual conference Days of the Bosnian-Herzegovinian American Academy of Arts and Sciences (BHAAAS), which was scheduled to be held in Mostar, Bosnia and Herzegovina in June 2020 but was postponed due to the coronavirus pandemic. However, in light of the high quality of the submissions, BHAAAS' technical and natural sciences division decided to create this special book despite the postponement. The editors would like to extend their special thanks to all the chairs of the planned symposia for their dedicated work in the production of this book: Jasmin KevriÄ, Zerina MaÅ¡etiÄ, Dželila MehanoviÄ (Computer Science); Anes KazagiÄ, Hajrudin Džafo, Izet SmajeviÄ (Mechanical Engineering); Tarik UzunoviÄ, Asif Å abanoviÄ, Jasmin KevriÄ (Mechatronics, Robotics and Embedded Systems); Mirza Å ariÄ, Tarik Hubana, Maja MuftiÄ DedoviÄ (Advanced Electrical Power Systems); Mirza Pozder, Naida AdemoviÄ, Medžida MuliÄ (Civil Engineering and Geodesy); Adnan MujezinoviÄ, Muris Torlak (Computer Modeling and Simulations for Engineering Applications); and Aljo MujÄiÄ, Edin MujÄiÄ (Information and Communication Technologies).
