Abstract: This paper discusses parameter optimization design and settings of automatic anti-skidding system for military vehicles on ice and snow road. The basic composition and installations of anti-skidding system as well as the basic work principles of anti-skidding system are introduced and analyzed according to kinematics, dynamics and driving principles the system provides. Then mathematics modeling and computer simulation carrying out optimization design are presented for this system.

Abstract: In recent years, with the development of mechanical automation,automation system had been developed quickly, and it covers different fields in different areas. As for automation learning system, it had been developed by some researchers and learners for its fast speed and energy-saving properties. At the same time, automation learning system is also useful for trainers to develop and improve. Therefore, the author had made some investigations and tried to dig out its advantages and disadvantages, which are useful for its further development in the future application. During the study, the author also found that some electronic materials had been useful to stimulate the uses of automation learning system.From the study, the author hopes that the study will help to improve learning efficiency and saving energy.

Abstract: The method of water quality monitoring applied by reservoirs is sampling in the scene and analyzing at the laboratory at present. Based on analyzing key problem of water quality monitoring, automatic water quality monitoring system based on GPRS is provided in this paper. The system structure and principle are introduced. The system collects, transmits and processes water quality parameters automatically, so the production efficiency and the economy benefit are improved greatly.

Abstract: To meet the demand of communication automation for outfield equipment test module, special embedded system was proposed by combing host computer control board and signal acquisition board, taking advantage of high data transmission efficiency on PC104 bus. Multichannel switch, signal recuperation circuit and Analog to Digital Converter (ADC) were controlled by FPGA logic on signal acquisition board. Signal data acquired were transmitted to host computer control board to display for user in real time. Application shows that the system was easy to operate. It performs well on real time ability and stability.

Abstract: The input and output axis equipment is designed in the mechanical automation test platform. The input axis pull (positive pull) completes the noise test of the transmission at different gears. The output axis pull (reverse pull) test the shifting at different gears. The rotate speed adjustment of the input electromotor is done by transducer, and the rotate speed and torque design of the output electromotor is completed by the servo system. The mechanical automation electric control system of automobile transmission assembly test platform was designed. The working condition of the analogue automobile is achieved by means of the electric control systems control over the input electromotor and the output electromotors repeated power switch.

Abstract: Focusing on electric automation with the reactive optimization for power system which is a nonlinear object with multiple variables and constraint conditions, the paper presents an optimal method based on Taboo Search and Genetic Algorithm, which inherits and develops the advantages of multiple search and high robust performance of Genetic Algorithm, and the high climbing ability of Taboo Search to improve the convergence performance and speed. The simulation for IEEE30 node system proves that the method introduced in the paper is appropriate and efficient in the field of electric automation.

Abstract: This article causes for the different sub-word ambiguity problem, the sub-word dictionary based on the design of the traditional mechanical segmentation algorithm improvements, according to "priority" and "a maximum of sub-word" the principle of long-term, proposed the dynamic maximum points word algorithm and up Segmentation in communication material. And use of open source code java word segmentation algorithm to achieve the design in communication material.

Abstract: In this paper, the semantics of the video image in different size, different levels of abstraction inherent in the semantic concept relations is proposed based on lexical semantic relations between concepts, with Word-Net tree concept hierarchy to organize marked keywords and search keywords thought, between the two images semantic similarity measure convert path from Word-Net concept between the nodes in communication material. The relationship between image semantic concepts is to measure and matching.
