In order to solve the key setting difficulty and the key security problem in the file encryption, key distributed storage technology may be a proper choice to help improve the safety of the key. In the paper, a novel secret sharing scheme is proposed by AES encryption algorithm for file confidentiality, dynamic key generation mechanism to generate keys, multisecret-sharing ideas on key pre-treatment, using Shamir threshold scheme for secret dispersed storage. Finally, a few tests are carried out and the test results suggest that the efficiency of the whole scheme is good.

Based on Ontology Model for the Semantic Web, this paper proposed a new Information Retrieval System. The system combined a new vector space model based on the concept semantic retrieval and retrieval. Based on the factors like semantic coincidence degree, the concept in the concept semantic model was divided into upper-lower relationship and non-upper-lower relationship for calculating the similarity value between semantic concepts. The system also introduced the Information-Gain, which effectively controlled the semantic extension. The experiment shows that the system utilized the concept semantic information fully and the computation result was reasonable.

Touch screen has a very wide range of applications.Most of them are used in public information inquiries,for instance,service inquiries in telecommunication bureau,tax bureau,bank system,electric department … Touch screen can also be used for entertainment and virtual reality applications too.Traditionally,touch screen was composed of pairs of infrared LED and correspondent receivers which were all installed in the screen frame.Arrays of LED were set in the adjacent sides of the frame of an infrared touch screen while arrays of the infrared receivers were fixed in each opposite side,so that the infrared detecting network was formed.While the infrared touch screen has some technical limitations nowadays such as the low resolution,limitations of touching methods and fault response due to environmental disturbances.The plastic material has a relatively high absorption rate for infrared light,which greatly limits the size of the touch screen.Our design use laser diode as source and change the traditional inner structure of touch screen.by using a light pipe with microstructures.The geometric parameters of the light pipe and the microstructures were obtained through equation solving.Simulation results prove that the design method for touch screen proposed in this paper could achieve high resolution ratio(R.R.) and large size of touch screen.

This document studies a method of MIMO channel modeling and simulation for mobile communication system. Both spatial correlation and fading in time domain are integrated into this model, and many channel parameters such as time dispersion, Doppler effect, direction of arrival, azimuth spread, and power azimuth spectrum are fully considered in this model. We simulate this MIMO channel according to the parameters of 3GPP.25.996.The result show that the new method matches the analytical result very well.
