Introduction The technique of mobile satellite communication can ensure carriers like vehicles, ships, or planes, continuously transmit multimedia information, such as vocal , graphic or HD(high definition) video data, via synchronous satellites while they are in motion.
The speed reducer can be considered as a proportional segment with a reduction ratio of 115:1.
The gyro placed on the carrier detects the status of movement and sends data back to the controller, so that the control signal produced before the deviation generated.

Therefore, the reduction of using fossil fuels is urgent and replacing them with ideal energy source (an ideal energy source should be renewable and have minimal effects on environment [1]) is essential to provide a livable and unpolluted environment for next generations [2].
The two-equation turbulence models was realize k-e [11].The experimental data was compared with the simulation results taken from [12].mesh structure, computational domain and result shown in Fig.1 and 2.

Furthermore, it conforms to the environmental protection concept of green energy, energy conservation and emissions reduction.
Distributed temperature sensors are equipped in the car to collect and record the real-time temperature and provide data support for the accurate control of the temperature.
Since this system has a strict requirement on the power consumption and involves a large number of data processing, the architecture with the ultralow-power MSP430F149 MCU as the main body is adopted.

Between AC and many AP through the CAPWAP communication protocol (11), AC may be useful for each AP in the network working state and the adjustment results are monitored, every information collection cycle, then control the tunnel through the CAPWAP, the information collection instructions to each AP, each AP in turn to collect its neighbor information (neighbor AP name, accept power), these information through data tunnel upload to AC information collecting and sorting, constructed by AC related data structure to maintain global network information.
Fig.4 Dynamic channel emulation effect adjustment Conclusion This paper studies the interference problem of dense deployment of WLAN under the AP, based on the study of various algorithms, gives a dynamic channel allocation in a centralized architecture of the WLAN algorithm, the algorithm can reduce the storage and computational burden of AP, the algorithm runs before without knowing the AP position, can be adjusted timely according to the network channel the situation changes, the reduction in AP interference at the same time, realized the radical In the channel of AP number of load balance, NS2 simulation results show that the algorithm is simple and effective.

The functional tolerancing is now widely accepted by industry, as this approach contributes to a reduction of manufacturing costs while improving product quality [1].
In order to determine the displacement of each point in the analysis direction, all the parts are assumed to be perfect and only the surfaces of the studied junction have defects related to the datum system.
And the transfer relation depends on the preponderance order of the datum system.
For this mechanism, if the plane is the primary datum and the cylinder is the secondary datum, the transfer relationship will be different.

This result has been confirmed by Dynamic Light Scattering analysis data.
ü FTIR spectra and DLS analysis data, confirmed formation of chemical bonds of Fe-O-Si on to the surface of Fe3O4 nanoparticles.

Introduction Lightweight is the inevitable trend of car energy conservation and emissions reduction, so it is a new topic that development and application high strength steel flexible roll forming automobile components with light weight, high strength and good safety performance in auto parts and machinery manufacturing field.
On abroad, Germany Darmstadt University and data M company, as well as Japan Takushoku University is the first study in this direction; In China, North China University of Technology in support of the National Natural Science Foundation of China has been successfully developed single and double axis flexible roll forming machine, and has a lot of researches and experiments.
According to relevant data of material tensile test, it should be defined as 0.099 which is maximum strain in the stage of material plastic deformation.

Many tools have been developed to enable the interpretation of GPR data.
During propagation in a particular medium, geometric and physical attenuation mechanisms lead to reduction of the electromagnetic signal strength.
