An environment control and life support system (ECLSS) is an important system in a space station. The ECLSS is a typical complex system, and the real-time simulation technology can help to accelerate its research process by using distributed hardware in a loop simulation system. An implicit fixed time step numerical integration method is recommended for a real-time simulation system with time-varying...
Optical fiber pre-warning system (OFPS) is widely utilized in pipeline transport fields. The intrusions of OFPS need to be located. In this system, the original signals consist of noises, interferences, and intrusion signals. Here, noises are background and harmless interferences possessing with high power, and the intrusion signals are the main target of detection in this system. Hence, the study...
An alternative method using the ground heat exchanger to provide cooling water for a solar-driven CACS is proposed with the aim to improve the performance. Using a mathematical model developed in this study, theoretical analyses are carried out to investigate the performance of the combined system. The results show that with an additional compressor, the system can be driven by 50°C hot water, and...
