An approach to integrated guidance/autopilot design for missiles against maneuvering targets on the sea is studied. When the integrated guidance/autopilot model of the yaw plane is formulated, the guidance/control law is designed based on the backstepping idea and variable structure control theory. For the unavailable information of the maneuvering target, an estimating method is given. Finally, to verify the effectiveness and rightness of the integrated design scheme, the simulation of some antivessel missile against high maneuvering targets have been made, the simulation results have shown that high accuracy of hitting target can be got.

A new silicon-based amperometric microelectrode biosensor made with bulk micromachining technology is provided. We designed this new biosensor and fabricated it with anisotropic silicon wet etching technique. P-type silicon wafers, Au and SU-8 are used for making substrate, microelectrode and micro reaction pool respectively. To our knowledge, consecutive platinization and polymerization of pyrrole is firstly used consecutively for microelectrode surface modification. The sensor aims for low unit cost, small dimensions and compatibility with CMOS technology. SU-8 micro reaction pools are made to contain detection solution to reduce reagent volume and unit cost. Bulk micromachining, platinization and polymerization of pyrrole enhance sensitive coefficient, thus helping to miniaturize its dimensions and to reduce unit cost. Using p-type silicon wafers as substrates make compatibility with CMOS technology possible. Successful experimental results have been achieved for glucose detection. Compared to conventional amperometric biosensors and amperometric microelectrode biosensors made with surface micromachining technology, it has several advantages, such as smaller sensing surface area (1 mm /spl times/ 1 mm), lower detection limit (1/spl times/10/sup -4/ M), larger sensitive coefficient (39.640 nA mM/sup -1/ mm/sup -2/), broader linear range (1/spl times/10/sup -4/-1/spl times//sup -2/ M), better replicability (3.2% RSD for five respective detections) and stability (enzyme efficiency remains well above 95% after being stored for a month), easier to be made into arrays and to be integrated with processing circuitry, etc.

A digital conversion system that converts GPIB industry bus into USB universal bus has been developed. The output signal of fiber optic gyroscope is received and processed through this system. An friendly human-machine interface is realized by using hardware, which connects Lock-in Amplifier with PC computer, and by using software, which evaluates the performance of fiber optical gyroscope through FOG parameter such as bias stability, scale factor and so on. In this system, the USB interface is connected with PC computer, and the GPIB interface is connected with SR844, but all the interface function is realized through FPGA. With a digital sampling and processing system designed with VC++, the real time controlling procedure, high-speed receiving and sending data can be carried out under Windows platform, and the results can be displayed, too. So the design of the system is flexible. The reliability and the stability will be improved, error rate will be reduced, and the efficiency will be advanced. Meanwhile, standardization and complete digitalization will be realized in the test system for fiber optic gyroscope as well.

Independent component analysis (ICA) is a new method of signal separation developed in recent years. In this paper, the fundamental theory and algorithm of ICA are introduced, and the implementation of ICA method in fingerprint image preprocessing is discussed to separate the fingerprint from background texture. ICA requires the number of observations should be no less than that of independent sources. So it is impossible to apply ICA to a single image directly. The paper presents a technique to generate three input signals from one single image, and then, process it by ICA. The experiment results illustrate that ICA has better performance than traditional methods.

Text categorization is the basic technology of information process, query and retrieval. This paper introduces some improvements of the Bayes categorization algorithm based on an advanced research on current algorithm. In addition, it considers the probable risk of mistaking the related text for unrelated one during the text categorization and puts forward a proposal of a text categorization model of minimal-risk Bayes decision. The results of our experiments prove that it promotes the precision of text categorization.

The grey theory, one of the methods that are used to study uncertainty, is superior in theoretical analysis of systems with imprecise information and incomplete samples. In this paper we summarize the principles of the theory and its modeling schemes in prediction and diagnosis, and review its practical applications so as to give some heuristic guidelines for improving the information acquisition technology.

A computational model of object-based selective visual attention is introduced. What are the units of selective attention is always the focus of selective attention. Most existing computational model of selective attention is space-based, but more and more neuroscience experiments indicate that it is object-based. For object-based attention, how to define "object" is the biggest difficulty and it is generally accepted that the "object" refers to "perceptual object" which is created by Gestalt rules. However, Gestalt rules are very difficult to be calculated in images. The model presented in this paper is comprised of two independent components. One component is object-based segmentation by using perceptual color cues, the other is the generation of a object-based saliency-map in terms of the inhibition of return mechanism. Lastly, the results of experiments show that the model is valid.
