File Intertransmission Based on WinSock Component

WinSock is a group of API,which is used to transmit data and exchange information on Internet,the Socket Application programme impoldered by users may communicate with other Socket Application programes by Internet. Delphi provides Socket components,which sustains the TCP/IP protocol and makes the Internet programming acquiring much more flexibility.This paper probes that how to realize transmission of files in any format under nonblocking mode between clients and servers by means of Socket components of Delphi.     

Lighting Design of Chinese Traditional Buildings and Application of New Type of Little Power LED

This paper is a part of the research on the lighting techniques of the traditional Chinese buildings in Summer Palace,Beijing,which is a sub-project of the Municipal Research Project on the Correlative Techniques for Beijing's Sustainable Development(Y0604017040391).The work,which the authors took part in,on the most representative Chinese traditional buildings in Summer Palace,is taken as a case study on lighting design and lab simulated experiments and checked by practical result,illustrating a working frame for other similar lighting design works.     

Research Development of the Conductive Polymer Materials -PAN

According to the present research situation of conductive polymer materials- polyaniline (PAN) ,we reviewed the structure and properties of PAN, the effecting factors and the best conditions of electrochemical synthesis and chemical synthesis of PAN , the doping mechanism of PAN, inorganic and organic acid doping,secondary doping, the method of increase soublity and processability of PAN and the broad application of PAN. The development derection and prospect of PAN are pointed out.     

Stability Ishikawa Iteration Procdeure for Strongly Pseudocontractive Operator and Strongly Accretive Operator Equations

By virtue of some analysis techniques,it is proved that certain ishikawa iteration procdeure with errors are stable with respect to strongly pseudocontractive operators in real Banach space. A related result deals with stable iteration procedures for solution of the nonlinear equation of strongly accretive operators. The results presented extend and improve the corresponding by Osilike,Zeng, Chidume, Deng, Liu,et al.     

Automatic Fingerprint Classification by GA-Based Neural Network

Fingerprint classification can provide an important indexing mechanism in a fingerprint database. An accurate and consistent classification can greatly reduce fingerprint matching time for large database. In the paper, by combining genetic algorithm and neural network is presented a fingerprint classification algorithm which is able to achieve an accurate classification. By inputting the global feature represented by directional image to three layer neural network trained by genetic algorithm, the fingerprints were classified into six categories: whorl, right loop, left loop, arch, double loop and undiscerning type successfully.     

Preparation of Electrochromic and Transparent Film of Polyaniline

The preparation method of transparent film of electrochromism polyaniline on the glass supporter is studied by a dipping polymerization. The electric and optic properities of the resulting film are measured as a function of oxidant,dopant,reaction time and temperature.The optimum technology term is obtained in the normal atmospheric temperature.The experimental result is testified by fuzzy set theory.
