The data layer is a database management system, which it defines and manages the contact of the database and the application and it is responsible for the management of read and write data in the database.
Diagnostic database established by the framework standard achieve a shared of diagnostic data formats and specifications.
As long as the data comply with the standard, the system can identify.
The data maintenance module is used by a modular structure of B/S mode, and developed by the VC language.
Only the client has installed data maintenance module subroutine and the users have been authenticated, they have permission to access the data maintenance module.

In order to minimize dynamic noise value and optimize the helical gear design parameters, we give the relation formula between parameters of gear and noise, according to the simulation data by regression method.
The results provide quantitative research methods for the gear noise reduction technology.

Currently the circuit has been produced, and the simulation results can be compared with the test data to verify the waveguide design.

As expected, the reflectance does have a reduction besides the great vibration being completely unexpected.
According to simulation data, the light absorption rate of material can be enhanced from 0.05% to 50% via appropriate microstructure.

So the reduced service life of the cutting arm, increased maintenance costs, reduction in production efficiency and the vibration in the work process became an increasingly focus[4].
The natural frequencies data of each part were calculated with finite element software ANSYS, as shown in Table 1.

In comparison with conventional gear mechanisms, cycloid drives have been developed to achieve a high reduction ratio ,very high precision and small size, making them attractive for limited space applications, such as robots, machine tools, linear axis positioning systems and a wide variety of factory automation equipment[1].
The data of point M locus can be output into a txt file.

One advantage of compliant mechanisms is the potential for a dramatic reduction in the total number of parts required to accomplish a specified task.
All the signals are amplified and sampled by a data acquisition card PCI-818HD which is supported by Real-Time Windows Target of MATLAB.

Introduction Energy conservation and emission reduction is one of the basic state policies in China.Heating, Ventilating and Air Conditioning (HVAC)[1],as the high energy consumption equipment,is widely used in scientific research and production work.It is workers’ duties and obligations to search a better method about air conditioning energy saving.According the existing equipment,climate condition of territory of use and economical efficiency,design and transform a set of equipment,which takes advantage of the natural air cooling in winter and replaces the former refrigerating unit .As a result,the replacement reduces the service time of unit cooler ,decreases the energy consumption,prolong the working life of equipments ,and save considerable cost.
Analysis of Main Equipments’ Energy Consumption and Energy Saving Performance Before transformation,the WCFX12A0 refrigerating unit keeps working,its main equipments’ energy consumption as follow:totally enclosed type screw compressor-11Kw,cooling tower fan-5Kw ,cooling water pump-5.5Kw,chilled water pump-11Kw,energy dissipation per hour is 131.5Kw.h.After transformation,the energy dissipation is 11Kw when the cooling water pump is opened merely,which reduce the expenditure of energy tremendously.In real work,the working time of using air cooler to replace the refrigeration compressor to supply cooling capacity is about 1560 hours,which saves electric energy 187980Kw.h.According to the difference between the former and later unit,workers did a series of detailed comparison based on the data statistics,the mean parameters as follow: Table.2 Energy consumption of cooling correlation table of air-cooled cooler and refrigeration compressor Air-cooled cooler Refrigeration compressor New

After noise reduction, amplification and demodulation, we can get each LED’s absolute location.
Record data every 2.5cm.

Introduction Tensile data at 723 K (450°C), reported in [1] and obtained at strain rates ranging from 5x10-4 to 3x10-1 s-1, were used from Jarrar et al. [2] to fit the following single-term phenomenological constitutive model: (1) (2) (3) This model has been previously applied successfully in finite element simulations of superplastic forming processes of both aluminum and magnesium based alloys [3-5].
It is possible to note that the average grain size and the current area fraction of voids increase with forming pressure involving a reduction of the dome apex thickness.
