An ant colony optimization (ACO) based multiuser detection (MUD) for the receive-diversity aided space-time block coding (STBC) systems is proposed. The ants are allowed to deposit pheromone based on the concept of Pareto optimality, using the information from the individual antennas independently. Simulations show that detector employing the Pareto optimality has enhanced bit-error-rate (BER) performance. Beside, the proposed ACO-MUD not only outperforms the genetic algorithm approach in BER performance, but also avoids the BER floor that the genetic algorithm encountered.

Kernels are employed in Support Vector Machines (SVM) to map the nonlinear model into a higher dimensional feature space where the linear learning is adopted. Every kernel has its advantages and disadvantages. Preferably, the ‘good’ characteristics of two or more kernels should be combined. In this paper, the mathematical formulation of multiple kernel learning is given. To enhance the robust regression of the algorithm, KPCA is used for the support vectors' reduced process. Through the implementation for average molecular weight in polyacrylonitrile productive process, it demonstrates the good performance of the proposed method compared to single kernel.

A novel energy management control strategy for stand-alone PV system is proposed. The solar cell array powers the steady state energy and the battery compensates the dynamic energy in the system. The goal of the energy management control strategy is to control the un-directional DC-DC converter and bi-direction DC-DC converter to operate in suitable modes according to the condition of solar cell and battery, so as to coordinate the two sources of solar cell and battery supplying power and ensure the system operates with high efficiency and behaviors with good dynamic performance. A 500W experimental prototype of stand-alone photovoltaic power system was built in the lab. Experimental results are shown to verify the effectiveness of the proposed energy management strategy.

Preemptive scheduling problem of a single machine subject to arbitrary release dates under uncertain situation is discussed. The release dates of jobs are independence and different with each other. Uncertainty means due dates are not accurate, which can be described by fuzzy set. The memberships of fuzzy due dates denote grade of satisfaction of completion times of corresponding jobs. The objective of the problem is to find an optimal schedule which maximizes the minimal grade of satisfaction of jobs completion times with respect to fuzzy due dates. By extending the method of corresponding problem with accurate due dates into fuzzy situation for the problem, an O(n2) algorithm is presented.

Currently, most electronic toll collection (ETC) systems around the world are implemented by DSRC (dedicated short range communication) technology. However global positioning system technique is applied to ETC to replace DSRC technique in recent years. It is an innovative technology for Expressway Network electronic toll collection solution, which is totally different scheme comparing to traditional DSRC-based technology. In this paper, the frame composing and working flow of the system are described, the design of GPS-based ETC system are discussed detailedly, and the advantages and disadvantages of the system are discussed at last.

Traditional PLC software about programming and monitoring all were designed in serial port debugging mode based on local. So the remote monitoring and controlling function couldn't be realized in the mode. In the article the virtual serial port (VSP) technology was imported into the system and it turned the PLC serial port software from local control function to remote one. In the system, the real serial port was replaced by virtual one. The client captured the command frames getting across the VSP, and then the instructions were sent to server through internet. And server program transferred the command to PLC by real serial port of local upper computer and correlation datum backtracked after PLC response. The Cx-programmer (Omron PLC software) was applied in the experiment and the ladder of Cx-p come into being switching on and disconnecting by returning datum. And according to the changes, the running state of local equipments could be known. This system was debugged by the experiment successfully.

With extension of simulation scale and deep development of modeling technique, increasing demands are placed on natural environment truthfulness simulation in all kinds of simulation technique domain. In VRML, the two frequently used programming nodes are Background and Fog. Background node is regularly used to produce virtual space background, maybe either gradient rendering background or panoramagram rendering background, further linking the two. Fog node is mainly used to produce VRML virtual atmosphere effect. Scene's fogging treatment should not only reflect fog's objective existence, but also give an expression of fine effects of fog light and shade, creating an obscure meaning of poem. Paper mainly introduced these two kinds of virtual atmosphere and space natural simulation technology and their design application.
