To improve compression capacity, motion compensation (MC) is utilized in H.264, which includes 6-tap FIR for 1/2-pel interpolation and 2-tap filter for 1/4-pel interpolation. MC uses up most decoding time, and is the expensive part of H.264 decoder. Some consumer electronics, such as smartphones, may not have enough processing capability to decode high definition video program in real time. MC must...
A direct torque control (DTC) strategy for dual-three phase induction machine with one stator winding open-circuited is discussed in this paper. An optimums election scheme of space voltage vector is proposed based on fuzzy control and direct torque control. The largest space voltage vectors are selected to control the machine. To verify the presented method, fuzzy direct torque control of dual-three...
This paper gives a way of implementing a high-speed and reliable data conversion between UART and WLAN. After introducing the overview of our system, this paper shows the hardware structure and firmware design in brief. Then we analyze the bottleneck of the data conversion and give a way of how to improve and optimize the firmware to complete a highspeed and reliable data conversion in detail. We...
In the case of wind energy resources identified, wind farm micro-layout mainly involves the arrangement of the wind turbines including to define the number of the turbines and the space between them. In this paper, such impact factors on the wind farm micro-layout as topography, geomorphology, turbulence, wake and economic features of the wind farm are analyzed, and the model for optimization of the...
Under the four-component wind speed model, the wind turbine output power was researched based on the Jensen wake model, which combined of the dynamic wind turbine model; anglicizing with the distribution of wind power from the theoretical, optimization method that named quadratic interpolation was used, and the optimization tool of Matlab\Simulink verified that the correct conclusion has a certain...
