Abstract: Aiming the lubricating oil quality can cause the machine failure and decrease operating time, its impurities can also change the oil capacitance, the online detecting system which based on the LabVIEW virtual programming language is designed. LabVIEW can make data collection, processing, display, memory, etc, implementing the online monitoring of the lubricating oil. This design greatly decrease the workload of the staff, reduce the detecting time, raise the testing efficiency of the equipment and measure the various impurity content of lubricating oil more accuracy.

Abstract: Perfect turn can help micromouse get a right maze information and high turning speed in complex maze, lead to a win in the competition, but high speed makes control the micromouse very difficult. How to calibrate a turning of a micromouse has become very important. Through analysis of a turn different motion results, get perfect turning reference, then set start and end to record position ratio, get the converted data, sum the data until the mouse complete half turn. After checking, the mouse know whether it is on the under path or over path, then it will automatically ask motors make some action to put itself back to the perfect path, a perfect turn is realized.

Abstract: Computer modeling and simulation of thermal analysis of a satellite borne electric box is introduced in this paper. Simplified geometry was built and meshed to get a finite element model. Then the environmental conditions were defined, the work case was analyzed, and the influence of the parameter of a thermal contact resistance was discussed.

Abstract: Because traditional displacement form of 3D acoustic perfectly matched layer (PML) absorbing condition needs to split the displacement into three parts, which requires solving a third-order differential equation in time and occupies a large amount of memory. In order to solve the above problems, this paper puts forward an Convolution approximating PML absorbing boundary condition based on the previous works, and discusses the basic construction of the traditional perfectly matched layer absorbing boundary condition and the new arithmetic in detail, then the new method is compared with absorbing condition of low order paraxial approximation and traditional PML, investigating the absorbing effects of 3D acoustic wave’s numerical records.

Abstract: The design using CVRCON control and drive the oscillating circuit, making the oscillating circuit resonant coupling, realizing the wireless transmission of power, and allowing the LED lights can be lit. The key can adjust the sampling resistor value, changing the transmit power, and controlling the LED brightness.

Abstract: As we all know, glass instrument reactive substances in Physical, chemical experiments, bloom residue attached to the inner wall of the instrument after a chemical reaction, often heated to high temperatures or placed the longer reactive substances glass instrument, but not easy to clean. Use unclean instruments, will affect the experimental results, and even let the experimenter observed error phenomenon, induction, reasoning out the wrong conclusions. Therefore, the chemical experiments using glass instruments must be washed clean. In this paper, by using ordinary scrub, ultrasonic cleaning, using a muffle furnace or oven drying, last extraction air form headspace and using GC-MS to detect it, then you will know glass instrument is thoroughly clean or not.

Abstract: Non-linear energy harvesting system was project to enhance interaction to ambient vibration that is wide band and low power which difficult the design for resonant solution. To improve efficiency of a non-linear design it was project a control system based in optimal linear control (OLC). Applying numerical evaluations it was possible to analyze the kinetic energy from the system as also the resulting output voltage. As main result there was a considerable increase of output voltage due controlled system in comparison to open loop for the same excitation.

Abstract: This paper introduces the reactive power compensation technology in the development of power system. From the new technology of reactive power compensation, controller, capacitor connection mode and switching on-off switch to briefly describes the current situation of the development of reactive compensation technology.

Abstract: Thetheoretical and technical problems related to the construction of an air-groundintegration land dynamic monitoring platform are discussed in the paper, andthe overall technical route and implementation plan of system platformconstruction are proposed. Firstly, the objective of platform construction isanalyzed. Then the aspects including technical route, development mode, systemstructure, and overall function of the platform construction are explained. Itis hoped that through the R&D of the platform, the modernization andscientific level of the land monitoring application can be improved, and a newtechnical support tool can be provided for the national land and resourcesmanagement Meanwhile, with the pilot platform, the application of 3S technique,space database technical in other geographic national conditions monitoringfield (including mineral resources dynamic monitoring, environmental changedynamic monitoring) is driven.

Abstract: From the perspective of vanadium battery charging-discharge efficiency, studies vanadium battery charging method by a series of charging and discharging tests, based on the principle of pulse, an pulse charging method with constant-voltage was introduced, compared with other charge method,the proposed method got the Stable discharge performance and the better charge-discharge efficiency.
