In the modern technological era, computers have become an indispensable tool in people’s lives. The cooling fan, as one of the key components for heat dissipation in computers, plays an important role. However, what problems arise if a computer lacks a cooling fan? 1. Overheating Issues: The main function of the cooling fan is to … Read more
AbstractThis study proposes a method for developing cyber-physical systems that starts from a high-level representation of the control algorithm, performs formal analysis of the algorithm, and conducts joint simulation of the algorithm with the controlled system at both high-level (abstracting the target processor) and low-level (including simulation of the target processor). The expected advantages are … Read more
