By combining the inherent parallelism of genetic algorithms with the high-speed parallelism of cluster system, a back analysis method of mechanical parameters based on a master-slave parallel genetic algorithm is presented. Several improved methods are adopted: real code is used to shorten the length of individual code and reduce the search space; dynamic tasks allocation is used to avoid uneven processor...
It is the top-notch choice of realizing the reform goal of university logistic socialization and university development that university logistic enterprises expand market. The university logictic enterprise must get help from the university, grap favorable opportunity to breakthrough, and step by step by steading campus' primary market, exloiting campus' auxiliary market, struggling off campus' trusteeship...
This paper introduces a process to select different test circuit using FPGA controlled pull and disconnection of relay matrix, so that multi-port equipment testing could be achieved. This design, to some extent, has a simplified circuit complexity and an increased, comparing to the test equipment previously used.
In order to improve the efficiency of video information storage of the video surveillance system, this paper proposes a mechanism based on buffer and anomaly detection algorithm for video storage. The algorithm uses anomaly detection mechanism, only stored anomaly video, and uses buffer mechanism to completely store exception video information. Compared with the current algorithm, while maintaining...
Cerberus is a tiny x86 virtual machine monitor. It allows security sensitive codes to be executed in an isolated circumstance. The codes could attest their integrity to a remote party by a two-step attestation provided by Cerberus. Cerberus does not require the security sensitive applications to be modified or recompiled to run on it. These applications are packaged with the operating systems as virtual...
According to the structure of generalized information resource, in this paper the evaluation index system of management information resource allocation is established. Based on the cloud gravity center theory, the allocation evaluation model is constructed. The cloud gravity center theory is the effective evaluation method.
Relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. In the past, most research efforts in 3D model retrieval field have focused on designing algorithms...
We have established the Markov model for long range correlated time series (LRCS), by analyzing their evolutionary characteristics, then defined a physical effective correlation length (ECL) of the LRCS, which reflects the predictability of the LRCS, and find that the ECL has a better power law relation with the long range correlated exponent (LRCE) of the LRCS. We apply the power law relation between...
Mode control features high robustness over parameter uncertainties and disturbances. System order will reduce when its state reaches the sliding mode surface, making the control method simplified. A kind of new method of improving dynamics performance of direct current motor speed control system is investigated in this paper. Strong robustness, dynamic and static performance is validated by experiments.
Light field rendering (LFR) is an image-based method for generating novel views from a set of camera images. When sample of camera array is sparse, conventional light field rendering would cause aliasing artifacts. We present a straightforward layer-based method that significantly removes the aliasing artifacts with no prior knowledge of the scene geometry. First, a sparse disparity map is generated...
E-commerce is an increasingly important channel for retailing commerce and business transactions. In order to solve the problems for lacking of both realistic for the goods presentation and the friendly interaction with user on the traditional E-commerce Websites, showing goods in a 3D circumstance and applying 3D retrieval tool are very useful in E-Commerce system. In this paper, we present X3D technique...
The execution of logs in business process is very important for the historical data analyzing, especially for the workflow mining. The goal of workflow mining is to collect corresponding data at runtime to support workflow design and analysis. The problems of implicit places and implicit transitions are analyzed in detail. In view of the shortage of α algorithm to resolve the implicit problems, an...
Small and Medium size Enterprises (SMEs) are considered as the backbone of the manufacturing industry in China, the need for sharing and exchanging information is becoming more and more important. After analyze business environment in Southwest China, a generic conceptual framework will be developed and a prototype implementation of the generic concepts will be benchmarked in system design of manufacturing...
This paper introduces a DSP optimization model based on data structure transformation and memory schedule for real-time image process. This model implements 4 critical methods: image block, image dimension reduction, DMA transfer and ping-pong cache, which makes use of DSP hardware feature and optimizes the data schedule among the external and internal memory and CPU, while processing 2D digital signal...
The equipment is a spaceflight electronic system. We have adopted the extrusion method under equal extruding temperature of 350 - 380°C. Based on stress-strain data gaining from isothermal compression experiment, adopts rigid - plastic finite element method, simulating isothermal-extrusion deformation of which the component is wrought magnesium alloy, emphatically discussing deformation force and...
A new algorithms based on discrete Hopfield network(DHNN) are proposed to blindly detect multi-value signals in this paper. Based on the relationship between received signals and projection operator of transmitted signals, the paper will construct new optimization performance functions to blindly detect signals, A quadratic programming performance functions with alphabet constraints is mapped to energy...
Conventional SPIHT compression is for a 2D image or image block with the same maximum feasible decomposition level in two directions, so, only the size of image or image block is symmetrical, that is to say the maximum feasible decomposition level in two directions must be same and the image sizes had better be equal to 2level such as 32, 64, 128 etc, the optimal compression performance can be acquired...
The hardware and software configurations of process automation system on roller-hearth heat treatment furnace are described. The design ideas and principles of control functions are introduced. Heat treatment schedule management, process parameter setting, plate temperature tracking, heating process dynamic control and production data statistics are included in the system. The production capacity...
Response surface method (RSM) is a set of mathematical and statistical methods for experimental design and evaluating the effects of variables and searching optimum conditions of variables to predict targeted responses. Oestrone (E1) is one of the most important steroid estrogens in sewage and waterbody. An internal standard method of HPLC-MS-MS for E1 is established with its operational parameters...
We observe the expression of HIF-1 after middle cerebral artery occlusion (MCAO) by immunohistochemical method.Thirty-six Sprague-Dawley healthy male rats, with body mass of 250-330 g, were used in this study. Thirty-six rats were randomized into 3 groups: pre-ischemia group, sham-operation group and control group, with 12 rats in each.Rats in the pre-ischemia group were created into pre-ischemia...
