RFID technology being applied for the field of tracking and locating application faces many challenges. In order to solve the problem, we design and construct a model of RFID-based tracking and locating system which is based on complex event processing, that is BCEPS model. BCEPS model consists of physical device layer, RFID data processing layer, event processing engine, application layer and ...

Underground gas storage are often subject to external dynamic loads, blast vibrations, and seismic disturbances, since they function as backup areas for the strategic national energy reserve, supply demand dispatch, storage. Currently, research on response characteristics, stability, disturbance control of underground storages under loads is still incomplete great practical importance ensure se...

Underground gas storage (UGS) is an important part of the natural industry. Its peaking characteristics and capacity are critical to national energy supply security. Compared with mature market in Europe, construction UGSs China faces many challenges. This study expected provide references for UGS through a detailed analysis calculations European underground storage. First, current status devel...

The objectives of this work are: (a) to present a new system for building heating which is based on underground energy storage, (b) develop mathematical model the system, and (c) optimise performance system. includes Photovoltaic Thermal Hybrid Solar Panels (PVT) panels with cooling, an evacuated solar collector water-to-water heat pump. Additionally, storage tanks, placed underground, are used...
