Hydrogen has a gravimetric energy density nearly 3 times that of gasoline, and yet does not emit carbon dioxide at all in burning. However, since hydrogen exists in a bulky gas form at ambient conditions, the problem in the safe and efficient storage of hydrogen is a serious obstacle to the commercial...

Because of the development of a smart grid and smart meter infrastructure, smart homes can use various energy management approaches. This study proposes the use of a Home Power Aware System (HPAS) and intuitive user interface to help household occupants to be aware of the state of electricity use involving...

This paper explorers the causal relationship between energy consumption and economic growth using data of Hebei Province. The study covers the period of 1980 to 2011.We have applied gene expression programming to analyses how they evolved together. Two ways adopted in the forecast, the one is based on...

Reservoir characteristics has always been one of the many core study petroleum geology, it is because the reservoir is the exploration and development of the most immediate target layer, gas-water as the fluid, they exist and sports venue is the reservoir, thus storage layer of oil and gas reserves,...

Present a new type of cubic mechanism, which based on the traditional serial manipulators and parallel manipulators, given the position and orientation of the whole mechanism and the output shaft force screw, theory of wrench of multi-rigid body adopted to find the inverse solution of force screw of...

A new type of hybrid cubic manipulator with six degree of freedom(DOF) suggested based on traditional serial manipulator and parallel manipulator, analytic geometry method adopted to find its forward solution of position, simple expression and exclusive result obtained, as well as its inverse solution...

In this paper, a full-wave rectifier (FWR) with zero standby leakage current for vibrational energy harvesting systems is presented. Conventional active FWRs where active diodes are used to reduce the diode voltage drop and increase the system efficiency are usually powered from the output. Nevertheless,...

Traffic generator is a key component in the verification and test platform for network switches. It can produce packets for different network protocols, and the generated traffic can simulate the real internet traffic. A novel traffic generator, different from general traffic generator structure, is...

Taking the Crossing Underneath construction and the subway engineering as the background ,considering the Crossing Underneath construction and the subway station structure located in the upper and lower two layers structure will influence each other, which has caused great difficulties of the excavation...
