Quality data collection processes and process parameters adjustment is the key element of Quality control processes. The content of process quality data collection and control include process monitoring and product quality testing. Process parameter monitoring can be achieved by measuring the characteristics of the related parameters. Process product quality testing can be achieved by direct measuring product quality characteristics in the process or processes interval. Process quality data collection and control system have been studied in this paper.

According to the deficiency of the traditional detecting method, this paper develops a set of intelligent automatically detecting system for the internal bore surface quality, which combined the image processing technology and pattern recognizing technology. The radius of image is detected using Least-squares fitting circle theory and circular degree is obtained through calculating circular surface fluctuations rate, and then the discriminant function tests to determine whether the work is qualified. The system has been successfully used in the detections for many mechanical parts' internal bore surface and approved to have a great practical value.

The traveling salesman problem (TSP) is a classical combinatorial optimization problem of operations research's area, which is simple to state. However, this problem is known to be NP-hard, and cannot be solved exactly in polynomial time. Therefore, it would seem to be an ideal candidate for nonstandard algorithmic ap-proaches, such as natural computation. Natural computation is the computational version of the process of extracting ideas from nature to develop computational sys-tems, those that take inspiration from nature for the development of novel problem-solving techniques. This paper is a survey of natural computation for the traveling salesman problem.

It is very difficulty and complication for the remote quality control in the network manufacture Environment, because of a lot of factors such as the complication of system, the multiplicity of the products, and the extensiveness of information and the higher requirements of the clients especially the different manufacture source of the parts, materials, equipments, processes, industrial standards, and the difference of the operators' skills. This paper begins with the analysis of characteristics of quality control under coordinated produce condition and obtains the architecture of quality coordinated control system in the remote manufacture;and then analyses the BP model of fuzzy neural network used in the collaborative quality control, finally uses an example to introduce the adjusting method of product quality target control in detail.

the method of statistical adaptive increment control based on control-cell is on the basis of periodic projection and adaptive increment control for detecting data. Programs have been made for analyzing dynamic parameter about Statistical and adaptive increment control. Analyzing adjustable increment for probability curve of relative increase for effective configuration of extending control-cell, probability curve of relative increase for full configuration of extending control-cell, it is proved that this method can converge to a statistical optimization and can be interference-free.

Accurate detection of moving targets is the main contents of researching for computer vision and image encoding, which has an extensive applicative prospect. The traditional dynamic template matching algorithm has the disadvantage when it detects the affine deformation target, it is easy to distinguish the target by mistake. For that reason, a novel improved dynamic template matching algorithm is proposed in this paper. Firstly, the improved temporal difference algorithm is used to detect the moving targets. Secondly, affine invariant moment is used as the invariable characteristic. Experimental results indicate that, compared with traditional dynamic template matching algorithm, our method has better detection performance.

At present, the automation technologies are widely utilized in coal mine. However, because automatic control of shearer hasn't been realized, the automation of the fully mechanized long-wall coal mining face is still an unresolved problem. The automatic adjustment height of the drum is the key technology of the shearer's automation. In order to realize the automatic adjustment height of the drum in the shearer, Artificial Immune theory was used to carry out self-adaptive memory cutting of the shearer in this paper. The methods of the path memory and data processing, self-adaptive cutting and manual amendment were researched in detail. Preliminary experiment has been done on the MG900/2210-WD shearer that was produced by Xi'an Coal Mining Machinery Company. The experimental result shows that self-adaptive memory cutting of the shearer based on Artificial immune is feasible and the control precision satisfies the demand of production.

The capacitive silicon micro-accelerometer as an important inertia device, applied in the autocar, consumer electronics, inertial guidance and so on, which has a wide application prospect. Improving the detection accuracy of capacitive accelerometer has been an important research direction, which is the key to reduce the noise, the noise mainly include the mechanical thermal noise and noise of electric circuits. Noise reduction measures were described, for example, the design of sensitive units, high-frequency carrier frequency range selected, the choice of amplifier operation and so on, to reduce noise and improve sensitivity. Through the testing of the effect of noise, the sensitivity is better than the relevant reports.
