Abstract.
Therefore it is very challenging to find out how to reduce the energy loss and heat generation in a conventional hydraulic system and what is the key for energy saving if a common pump is used to supply flow rate to the circuit, this is primarily due to using a controller for electro-hydraulic system is developed to improve the energy saving performance of the hydraulic system considerations.
The torque developed by the induction motor follows the equation below (6) Despising the voltage drop caused by the stator impedance, the magnetizing flux is found to be (7) where T is torque available on the shaft (N.m), fm is magnetizing flux (Wb), I2 is rotor current (A) depends on load, V1 is stator voltage (V), and k1&k2 are constants depend on material and on the machine design.

Abstract: With the popularity of wireless communication systems, the question of radio signal coverage is getting more and more attentions in corridor for high-rise buildings.
The four bands, 210MHz, 460MHz, 1.2GHz and 2.0GHz, are chosen as the key frequency bands for measurement.
Based on the experiment, when the frequency is higher than 2.0GHz, its transmission is much influenced by personnel's movement and metal material, and that the signal stability problem need to be carefully considered.
Because of more and more attention given by public on the problem of radio signal coverage in indoor buildings, this study [12] provides the theoretical guidance for the majority of engineering and technical personnel for the design and installation of the indoor wireless communication system.

Abstract: 30 MW straw power turbines are most suitable in the major corn producing areas in Northeast China.
The Comparion of Thermal economy Cogeneration Between Winter and Summer The thermal economy, which signifies the energy-saving ability of a power plant, is the key factor in analyzing energy utilization rate.
According to related material, currently, the big-scale coal-firing cogeneration of our country can reach a thermal efficiency as high as 85%[6], compared to which the thermal efficiency of straw power generation products is still low.
