By using two kinds of methods the formula on the relative sensitivity of single bridge is given. All factors affecting relative sensitivity are analyzed The sensitivity of slide bridge and its influence on the measured resistance Rx are discussed. The condition of the minimum relative error is theoretically given That is the place of the balance point should be chosen according to the ratio of the measured resistance Rx to the internal resistance Rg of the galvanometer in order to get the minimum relative error. Thereby, the theoretical evidence is offered to cut down experimental error by choosing best ratio N.

This paper concerns mainly about two approaches to implement the anamorphic fractional correlation operation. Firstly, the definition of anamorphic fractional correlation is introduced. Secondly, an optical approach of implementing the correlation operation is presented. Lastly, since the optical implementation is somewhat troublesome, we will show how to exploit the anamorphic fractional correlation by computer-generated holography.

However, the practicability of technology is more viable than an empty concept. The unified communications that have been popular for several years enters into practical stage of improving enterprise efficiency from the concept stage of publicity hype. This paper summarizes the enterprise construction ideas of unified communications and points for attention in construction, and uses a application case to illustrate that the unified communications can bring collaboration convenience for enterprises.

Finger-vein pattern can be applied to personal identification. But due to many reasons, the captured finger-vein images are blurred and contain a lot of noise. In this paper, we propose a new method to enhance the contrast of the finger-vein image. It consists of three parts: wavelet denoising, contrast enhancement and binary image. At first, we perform stationary wavelet decomposition and transform the image into four frequency bands: low frequency band LL, middle frequency bands LH and HL, and high frequency band HH. To different frequency bands, we design different denoising method. Then we select a special sort of histogram template equalization method to enhance the contrast of the finger-vein image. Finally, we get the binary image using the OTSU method. Our experimental results in this paper show that the proposed method can properly enhance the contrast of the finger-vein image and gets good effect.

An heterogeneous distributed system using middleware to finish the visit to each other between P2P and Web Service system is brought forward, and the safety and veracity of visit the service must be ensured. The blue print of middleware is to adding the function of visit Web Service onto the basic function of peer. The middleware provides the service accepting and disposal of request to the Web Service, and then it is responsible for discovering, calling service and returning result. On the basic of two heterogeneous systems visiting each other, in order to find the related service position, the UDDI is added to the middleware. In this way service can be found although simple information is given. In addition, several middleware can group as a peer group, when a common peer joins in the group service which can be provide to enlarge the scale of query and to ensure the safety of system.
