Video Encoding Optimization Based on DSP 2.1 Optimization of storage complexity Memory one of the main factors of the system overhead (chip area, power consumption, hardware costs, etc.), reducing the storage capacity is critical for the system.
Software pipelining is an instruction for the arrangement cycle operation mode within the technical, scheduling cycle instruction, making the loop iterations in parallel implementation. 3.2 Optimization result The purpose of video transmission and storage is to ensure the validity and reliability, requires coding to compress video image data as much as possible the amount of bandwidth and storage space to meet the objective constraints, but also consider other factors, Such as the coding delay, distortion (quality), coding complexity and fault-tolerant properties.
l Control flow instruction Flow control commands (if, switch, do, for, while) will lead to warp threads branch block, thus affecting the effective instruction throughput, will lead to different paths of execution threads.

6063 Aluminum Alloy Online Quenching Surface Heat Transfer Coefficient and the Temperature Field Simulation Hui Wanga and Haibo Yang b School of Mechanical Engineering, Science &Technology of Beijing, Beijing，China a wanghui0438@163.com ,byhb@ustb.edu.cn Keywords: 6063 aluminum alloy ; online quenching ;heat transfer coefficient ; ansys temperature field simulation Abstract.
Numerical simulation model simplified as follows: (1) Assume that profiles have uniform initial temperature, heat transfer properties is isotropic and does not consider the thermal radiation; (2) regardless of the specific structure of the nozzle and establish model with only its size.
Nozzle exit is defined as the velocity entrance ,cooling medium is water of 20 ℃.Using pressure outlet boundary conditions as the outlet boundary, namely a atmospheric pressure; Profile is 6063 and its thermal physical property parameters selected from reference [7].
The streamline along the axial direction of free jet area, fluid flow is not affected by profile’s surface; In the impact area, water impact with aluminum wall ,velocity in the stagnation region is small and the pressure is biggest and format large pressure gradient; Then enter the wall jet zone, the pressure recovery for static pressure.

Measurement of the Internal Relative Humidity Distribution in Concrete Jikai Zhoua, Xudong Chenb, Jian Zhangc and Xiaowei Kand College of Civil and Transportation Engineering, Hohai University, Nanjing, Jiangsu, 210098, China azhoujikai@163.com, bchenxudong.1212@163.com, czuzu1104@qq.com, dkan1986@163.com Keywords: Concrete; Internal Relative Humidity; New Measurement System Abstract: The internal relative humidity (RH) and humidity gradients in concrete at early ages have a significant influence upon the properties of concrete, where exists a great discrepancy among the test results under different methods.
It has great significance for researching shrinkage characteristic of concrete at early ages and the free water effect on the dynamic mechanical properties of concrete.
Considering the above factors, the humidity sensors used in the new measure system are a capacitive type of humidity sensors made in Switzerland (SHT7X, 6mm×20mm).
The property of the new measurement system was analyzed, and the changing laws of the internal RH in concrete are studied in this part.
That is, the moisture distribution in concrete was affected by self-desiccation as well as moisture diffusion of concrete.

The beneficial effects of nitrogen on the cyclic properties of most modern alloys have been analyzed in terms of the flow stress components, i.e. the internal and the effective stress.
However, different stainless steel types can also provide a very wide range of mechanical properties and they have the advantage of not needing for surface protection: i.e. storage tanks, vessels, etc.
This newly developed grade of DSS is even more resistant to pitting corrosion, crevice corrosion and stress corrosion cracking, as well as higher mechanical properties.
Hence, the knowledge of the parameters influencing the fatigue properties and thus the fatigue life and the fatigue response must be regarded as important variables for design criteria.

There are different at the sensing properties and detection principle of gas sensitive materials.
Hydrogen sensor detection principle is based on physical or chemical property change of gas sensitive material after the adsorption of hydrogen.
Hydrogen gas sensitive element is the core component of hydrogen sensor, testing results was directly affected by its performance.
Working temperature is one of the most important influence factors for hydrogen sensor.

Specific steps: (1)to find out the components of the foundation soil, that is determining the size and content of the large mass, such as rocks, tree roots and so on, to avoid the large objects becoming obstacles to the construction of cement-soil; (2)to determine the naturally stable moisture content of soil, while the dosage of cement-soil keeps the same, the strength of cement-soil increases with the decreasing of moisture content; (3)to determine the organic content: a high content of organic matter in soil will hinder the hydration reaction of the cement, and affect the strength increasing of cement-soil, so we must find out the amount of the organic matter, determine its influence degree on the strength of cement-soil, and take the corresponding measure; (4) to determine the PH value and sulfate content of soil, if the PH value is low, lime can be used to have a balance, and the sulphate resistant cement or other admixture should be chosen when the sulfate is too much; (5)to
