Resource management is a complicated problem in multiprocessor system. When tasks with real-time characteristic are scheduled on processor resource constraints such as CPU and memory have to be met, however, it is usually difficult for a system to ensure load balancing and resource constraints simultaneity. In order to handle this problem lots of algorithms have been brought forward. In this paper, a load balancing policy is proposed to manage and integrate processing resource of multiprocessor system which is used to send packets of packets flows on time. The policy dynamically predicts the wait time before a packet to be processed based on the load of the processor and the timestamp of the packet, and decides the migration of packet between processors to guarantee that the packets can be processed before deadline. This policy can not only increase the multiprocessor utilization but also enhance the capacity of the system against the jitter of load by packets migration between the processors as well. We use simulation experiment to show that the policy can reduce the possibility of packets delay and increase the concurrency of flows that the system can serve.1 © 2011 AICIT.

In order to perform a quantitative analysis of a casein element, we simulate the scattering characteristics of casein, analyze the effect of the shape of a sample cell and the light source wavelength in the detection equipment on the casein detection and establish a sensor model for casein detection. All of these aspects are based on researching the scattering characteristics of a casein micelle. Using Mie scattering, we establish the scattering models of casein, including a cylinder cross-section and a square sample cell. Through irradiating different sample cells, we have analyzed the light intensity at all angles, and the light sensitivity for different wavelengths. The simulation result indicates that a square sample cell at 0° and 90° is more amenable to the detection the light intensity, which technically can meet correlative requirements. According to the simulation results, we demonstrate the detection sample cell of the casein element by using wavelengths of 1333 nm and 1600 nm as the laser source.

In distributed systems, the server placement problem in which a new server has to compete with existing servers for user requests is important in planning of constructing new business service sites. In addition to minimizing cost, competition-aware server placement also needs to maximize the benefit of building a new server. This paper proposes a Tabu Search approach to optimize the problem in general graphs. Results from the simulation experiments show that it do has a better performance than both of the Greedy Add and Greedy Remove algorithms.

Orthogonal Frequency Division Multiplexing (OFDM) systems may suffer from both carrier frequency offset (CFO) and in-phase/quadrature-phase (I/Q) imbalance at the receiver front end. In this paper, a novel type of intercarrier interference (ICI) self-cancellation method using mirror mapping is proposed to combat these impairment. Based on the proposed novel method and by adopting two widely used mapping operations, we altogether derive two different mirror mapping schemes. Analysis and simulation results verify that the proposed mirror mapping schemes not only inherit the efficiency of the existing self-cancellation schemes in suppressing ICI caused by CFO but also have the ability of compressing or even eliminating IQ imbalance. © 2011 IEEE.

A variety of studies on Stereo Matching Algorithms present that the process of Stereo Matching Algorithms can be reduced to five stages. The core three stages of Stereo Matching Algorithms are the attainment of initial match cost, the generation of candidate match cost and parallax calculation. Based on this theoretical, the grading test platform for stereo matching methods was present, on the context of using vc++6.0 to realize class encapsulation in each stage. There are four kinds of image to control data stream and unified interface between classes in this platform. Testing platform was divided into three parts - area of images-displaying, area of time-displaying and area of parameter-input In the images-displaying area, different parameters can be selected to control the execution of different algorithms. In the time-displaying area, the length of time of different algorithms can be compared, meanwhile, the bottleneck to improve the real time of algorithms can be detected. Performance-checking experiments of the test platform show it is excellent;its structure is clear;its function is perfect;its operation is simple;its expansibility is good.

Automatic positioning system for big crane-form pipeline is mainly to achieve the precise positioning of circular opening and big crane-form pipeline, and it's also the auxiliary system of achieving automatic loading. In order to speed up the positioning and improve its precision, the system is designed to use a combined method of infrared and machine vision;infra-red is used to quickly positioning, while template matching and circle center detection are used to precise positioning. The system transmits the data of position of circular opening to PLC through serial port. And then, the big crane-form pipeline is controlled to backward, forward, lower and transport oil by PLC. The positioning of the system is precise and express.

There are some limitations when environment model of AS-R mobile robot is obtained by only using a separate CCD camera or ultrasonic sensor array. The BP neural network is designed to fuse information of the two sensors to obtain the robot's environment model in this paper. The input of BP neural network is the intercept and slope of the edge line obtained CCD camera and ultrasonic sensor arrays, which is processed by through the global coordinates of coordinate transformation. The output of BP network is the fused intercept and slope of the straight edge. Experiment shows that environment model is feasible for the AS-R mobile robot and the environment modeling method has more reliability and accuracy. © 2010 IEEE.
