To improve the performance of PSO (Particle Swarm Optimization), a modified algorithm named CDPSO (Colony Density Particle Swarm Optimization) is presented based on the comprehension that the space density character of particles embodies the convergence speed and global optimization ability of particle swarm. By the way of adopting dynamic nonconforming inertia coefficient and acceleration coefficient according to density factor, a high efficient global search PSO algorithm is achieved. For the purpose of application in underground engineering design conveniently, a new method of coupling CDPSO and FLAC, an excellent aided design software in underground engineering, is put forward. The CDPSO-FLAC coupling method implements the cooperation between optimization searching and safety calculation of engineering by embedding the CDPSO algorithm into computational kernel of FLAC. The method is used successfully in the support design of a northwest tunnel in China.
为了提高粒子群算法的性能，基于粒子的空间密度特征体现了粒子群的收敛速度和全局寻优能力，提出了一种改进的粒子群算法CDPSO (Colony Density Particle Swarm Optimization)。通过采用基于密度因子的动态惯性系数和加速度系数，实现了一种高效的全局搜索粒子群算法。为了方便地应用于地下工程设计，提出了一种将CDPSO与地下工程辅助设计软件FLAC进行耦合的新方法。CDPSO-FLAC耦合方法通过将CDPSO算法嵌入到FLAC计算核中，实现了优化搜索与工程安全计算的协同。该方法已成功应用于西北某隧道的支护设计中。

In the process of product manufacturing, control of assembly error will directly affect product working behavior. Variation of working behavior with assembly error was partitioned to three phases: compensation phase, rapid loss phase and total loss phase. Based on changing curve of product behavior, Function of behavior loss was constructed to describe behavior loss resulting from assembly error of a part of product. The conception and calculating method of behavior loss index (BLI) are given to reflect behavior changing status of whole product under certain assembly accuracy. Based on Jacobian- Torsor method, the Jacobian-Torsor tolerance model, considering impact factors of working condition, was extended and corrected, the assembly error resulted from working environment can be calculated. Combined with BLI, the calculated results can be used to forecast product behavior change lead by working load. The forecast can help to determine next measurement adopted. Finally, an example was used to demonstrate calculating procedure of given method.

Due to the large success of wireless networks and portable devices, the ubiquitous computing paradigm is becoming a reality. Service-oriented architectures are among the premier middleware approaches to coping with the dynamicity of ubiquitous computing environments. One of the most challenging objectives to be achieved in ubiquitous computing environments is to allow a user to perform tasks by composing on the fly the environment's service and resource components. In this paper we propose a general service composition model for ubiquitous computing which based on semantic service matchmaking and genetic algorithm-based optimization of service selection. Based on the model, a ubiquitous computing architecture is given.

To be represented in tabular form and graphical format in ship electronic navigation system, printing tidal material must be processed into textual information, which is completed by an automatic tide table recognition module consisting of a feature extractor and a classifier. In feature extraction, a new wavelet part grid feature is defined based on wavelet's directive characteristics. In classification phase, multi-class SVM classifier is used instead of neural networks. Experiments show that the wavelet grid feature has good stability and satisfactory distinction, and SVM classifiers have better generalization performance than that of neural networks.

Transmission control protocol (TCP) is a reliable, end-to-end transport protocol, which is widely used for data services and is very efficient for wired networks. However, experiments and research showed that TCP's congestion control algorithm performs very poorly over wireless sensor networks with degraded throughputs. This paper studies TCP's throughput issues in wireless sensor networks, and designs an improved congestion control algorithm based on the characteristics of the wireless sensor networks. The protocol is designed as extension to DCCP (datagram congestion control protocol) with a new congestion control component. We also implemented this congestion control algorithm in NS2.Simulation results show improvements on throughput achieved by using Extended congestion control algorithm.

A GPRS/GSM hybrid communication method is designed to develop a low-power RTU (remote terminal unit) for sensor signal acquisition and data transmission of distributed monitoring systems in industrial fields. The hardware architecture, key technology and transmission protocol of RTU are illustrated. Considering to GPRS network congestions, the reliability design of RTU is analyzed. When GPRS connection fails, the RTU switches to the SMS mode to resume the data transmission such that data integrity is ensured. Besides, the RTU is provided with multiple data sampling interfaces and low power mode. The data transmission experimental results show that the average GPRS transmission delay is 1.126~2.669 s, and the data loss rate decreases to 0 in hybrid communication from 6.94%, in single GPRS mode.
