Here are entered works on computer-based simulation of systems and processes, involving the formulation of a mathematical model, its conversion into a computer program, and execution of experiments with the computerized model for the understanding, evaluation, or design modification of the system or process of interest. --subdivision Computer simulation under topical headings, e.g. Psychology--Computer simulation
Here are entered works on electric generators, motors, transducers, sensing instruments, microphones, and similar devices, which convert electrical energy into mechanical energy, or the reverse, and which normally function as components of larger systems, e.g. electric power systems, information systems, control systems, etc.
