This paper proposes a self-structuring fuzzy neural network (SFNN) using asymmetric Gaussian membership functions in the structure and parameter learning phases. An adaptive self-structuring asymmetric fuzzy neural-network control (ASAFNC) system which consists of an SFNN controller and a robust controller is proposed. The SFNN controller uses an SFNN with structure and parameter learning phases to online mimic an ideal controller, simultaneously. The structure learning phase consists of the growing-and-pruning algorithms of fuzzy rules to achieve an optimal network structure, and the parameter learning phase adjusts the interconnection weights of neural network to achieve favorable approximation performance. The robust controller is designed to compensate for the modeling error between the SFNN controller and the ideal controller. An online training methodology is developed in the Lyapunov sense, and thus the stability of the closed-loop control system can be guaranteed. Finally, the proposed ASAFNC system is applied to a second-order chaotic dynamics system. The simulation results show that the proposed ASAFNC can achieve favorable tracking performance.

System and method of intelligent surveillance and analysis mainly used for monitoring whether a field has an intrusion object (such as a thief), and instantly providing video or image of the suspected intruder to approved relevant individual (such as the house owner) for further confirmation of the presence of the intrusion object (such as thief); therefore, the wrongful determination by the computer is avoided. The aforementioned system includes, first the determination and extraction of the contour of the suspected intrusion object, then the continuous tracking of the suspected intrusion object according to the contour, continue capturing of images using the camera, and then storing these captured video temporarily, and finally notifying the house owner using the highest definition image of the video which occupies a lesser amount of bandwidth through various communication channels once the presence of thief is determined; the video is downloaded using higher bandwidth, and is played.

A method for forming a semiconductor structure having a deep sub-micron or nano scale line-width is disclosed. Structure consisting of multiple photoresist layers is first formed on the substrate, then patterned using adequate exposure energy and development condition so that the bottom photoresist layer is not developed while the first under-cut resist groove is formed on top of the bottom photoresist layer. Anisotropic etching is then performed at a proper angle to the normal of the substrate surface, and a second resist groove is formed by the anisotropic etching. Finally, the metal evaporation process and the lift-off process are carried out and the Γ-shaped metal gate with nano scale line-width can be formed.

本發明揭露一種畫素驅動電路及其驅動方法與應用,在不同的時序下,此畫素驅動電路中係分別藉由三個薄膜電晶體以做為儲存電容與液晶電容的開關,首先先對儲存電容充入足夠的電量,並且將液晶電容進行放電,最後,重置儲存電容與液晶電容之間的電荷以達到對液晶電容進行充電的目的。因此,藉由本發明之電路設計並同時配合上適當的時序控制,即使在應用色彩序列驅動法的顯示裝置中,係可避免停止逐列掃瞄來切換背光光源,故,畫素充電的時間與發光的時間皆不會縮短,同時亦可使顯示裝置在更高頻率下操作,以提供較佳的畫面品質。
Kinetics and Mechanism of the NCN+NO2 Reaction Studied by Experiment and Theory

The rate constant for the NCN + NO2 reaction has been measured by a laser photolysis/laser-induced fluorescence technique in the temperature range of 260-296 K at pressures between 100 and 500 Torr with He and N-2 as buffer gases. The NCN radical was produced from the photolysis of NCN3 at 193 nm and monitored by laser-induced fluorescence with a dye laser at 329.01 nm. The rate constant was found to increase with pressure but decrease with temperature, indicating that the reaction occurs via a long-lived intermediate stabilized by collisions with buffer gas. The reaction mechanism and rate constant are also theoretically predicted for the temperature range of 200-2000 K and the He and N-2 pressure range of 10(-4) Torr to 1000 atm based on dual-channel Rice-Ramsperger-Kassel-Marcus (RRKM) theory with the potential energy surface evaluated at the G2M//B3LYP/6-311+G(d) level. In the low-temperature range (< 700 K), the most favorable reaction is the barrierless association channel that leads to the intermediate complex (NCN-NO2). At high temperature, the direct O-abstraction reaction with a barrier of 9.8 kcal/mol becomes the dominant channel. The rate constant calculated by RRKM theory agrees reasonably well with experimental data.

We have prepared semi-interpenetrating polyacrylate networks (PA/BA-m s-IPNs) through rapid photo-polymerization of a triacrylate monomer (TMPTA) in the presence of a photomitiator (1184), a tetramercaptane transfer agent (4SH), and N-methyl-bisbenzoxazine (BA-m). Next, we prepared novel fully interpenetrating polyacrylate (PA) and polybenzoxazine (PBZ) networks (PA/PBZ f-IPNs) through thermal polymerization of the BA-m monomer at 180 degrees C for 4 h. For the PA/BA-m s-IPNs, the BA-m monomers can be frozen and dispersed in the UV-cured PA network within 5 min to inhibit macrophase separation. After thermal polymerization, the phenol units of the ring-opened PBZ segments can form a hydrogen-bonding interface with the carbonyl groups to improve the compatibility between the PBZ microdomains and the PA networks. From an analysis using Kissinger's method, the non-isothermal kinetics of the thermal polymerization for the PA/BA-m s-IPNs indicate that an increase in the PA content increased the steric hindrance of PBZ polymerization. We used DSC, TGA, and contact angle analyses to determine the glass transition temperature, thermal stability, and surface free energy, respectively, of the PA/PBZ f-IPNs. The thermal stability and surface free energy of these PA/PBZ f-IPNs display linear relationships with respect to the PBZ content. Crown Copyright (C) 2008 Published by Elsevier Ltd.
