In order to improve the safety of the braking process of high-speed train, the Yanagiba Knives brake disc heat dissipation structure needs to be optimized.The ANSYS-workbench software was used to establish a three-dimensional transient model.The temperature field simulation was performed on the brake discs with 8 different structural parameters bas
Background.The work is devoted to the problem of evaluating the effectiveness of extinguishing open fires of solid combustible substances and materials, as well as internal (closed) fires (if it is impossible to ensure the sealing of the protected volume) by gas fire extinguishing installations when using gas extinguishing agents with special physi
Chondromas usually affect the small bones of hand and feet and account for only 0.5% of all intracranial tumors.We present a case of a giant, supratentorial meningeal chondroma in a 19-year old male patient and discuss the preoperative diagnostic findings as well as the appropriate treatment options.A 19-old male presented Acoustic Guitar with head
Particle Swarm Optimization (PSO) is a classic and popularly used meta-heuristic algorithm in many real-life optimization problems due to its less computational complexity and simplicity.The binary version of PSO, known as BPSO, is used to solve binary optimization problems, such as feature selection.Like other meta-heuristic optimization technique
