In GPRS (General Packet Radio Service), the mobile station receives signals from the base station. The mobile station is either at the cell level or the routing area (RA) level. During the packet transmission the MS is tracked at the cell level and when there is no packet transmission, it is tracked at the routing area level. A READY TIMER (RT) mechanism was proposed in to determine when to switch...
We have studied the AC-4 algorithm and then present key value ordering heuristic forming the new solving algorithm BT-KVV, which is based on the AC-4 algorithm. This algorithm takes full advantage of the state information of the data structure used in the AC-4 algorithm after the process of arc consistency. The algorithm sorts the values of the variables' domain according to the key importance of...
In order to assure the quality of software maintainability evaluation, setting up a reasonable index system and distribute the index weights with reason is the most important thing. In this situation, this paper set up an index system of software maintainability evaluation firstly, based on two principles such as giving prominence to main indexes and that indexes are usually required be measurable...
As the complexity of the mine production, the mine production logistics system is a hybrid logistics system. According to the characteristics of mine production process, the paper analyzes the mine production logistics system and compares with some existing system modeling methods. For the characteristics of the mine production logistics system, it puts forward a modeling method based on Hybrid Petri...
This paper briefly introduces knowledge management and its objectives, content and value. In the meantime, the author illustrates his own understanding about the ways to improve corporation management through knowledge management.
A design of smart sensor network based on TMS320F2812 digital signal processor, ADXL001 acceleration sensor, AD7656 A/D converter, DS18B20 and CAN bus was introduced to establish a embeded system which can monitor the vehicle's working condition. The software and hardware of the system was described. Through writing wavelet de-noising and fault diagnosis programme in the DSP, the SNR was improved...
We studied the inside traders' optimal strategies and the impact of public information on competitive insider trading in the context of Holden and Subrahmanyan(1992)'s speculative market. We explicitly described the unique linear equilibrium and found that competition among inside traders leads to more informative equilibrium price. Public information is detrimental for insiders and beneficial for...
A digital image watermark algorithm based on Human Visual System (HVS) and chaotic system is presented. The positions and grey values of the watermark image pixels are shuffled by Arnold Cat Map in the spatial domain first. Then the shuffled image is encrypted by Chen's chaotic system continuously before embedding in the host image. Exploiting the excellent properties of the wavelet transform and...
In this paper, we study the following nonlinear nonconvex programming problem: {min f(x), s.t.gi(x) ≤ 0, ∈ M, M = {1, 2,⋯, m}. Under the condition that the feasible set is bounded and connected, and the feasible set does not satisfy the pseudo-normal cone conditions, we propose the combined homotopy method to solve this problem by constructing new constraint functions and a combined homotopy equation...
In this paper, we study the following Linear complementarity problem:M ∈ Rn×n, q ∈ Rn, find x ≥ 0, such that Mx + q ≥ 0 and xT (Mx + q) = 0. First of all, We study several properties of the P*-matrix,then we construct a combined homotopy equation, prove the existence and the convergence of the homotopy path, which is from any interior point to the solution of the problem. Numerical example shows that...
Image quality assessment takes an important position in image processing field. The structural similarity (SSIM) index describes the similarity of images more appropriately for the human visual system than the mean square error (MSE). By our studying deeply, it is found that the structural information is not represented very well. So there is some weakness about SSIM, especially for assessing the...
