Warehousing is an indispensable link in logistics. It's very necessary to monitor and manage warehousing synthetically for the warehousing developing so far. According to the characters of warehousing, we propose the concept, architecture and function of warehousing integrated supervisory control system (W-ISCS) based on the research and application in various industries. This paper firstly analyzes...
Reasonable forecast of the main cargo throughput has decisive significance for ports to improve their competitiveness and economic benefit. The traditional forecasting methods and models have been difficult to forecast the current needs. In this paper, in order to enhance accuracy of the main cargo throughput, three methods, which are Pearl curve model, moving average method and three exponential...
In order to solve the incompatibility between real-time property and realism, we introduce a method for 3D rock fracturing simulation based on the Havok Physical Engine in this paper. Firstly, during the model preprocessing stage, the seed points are inserted inside the model and the 3D Voronoi fragments are generated as many as the seed points. At the same time, the breakable linear constraints between...
When large scale disaster occurs suddenly, allocating scheme of the first batch of "life" emergency supplies directly determines rescue effect. To make lack loss evaluation of the supplies accordant with actual cases, this paper proposed nonlinear loss evaluation function, based on which constructed multi to multi constrained scheduling model with multi objectives. To improve the performance...
With the development of new media technology, video as the most intuitive and effective media to give people more information. Along with a variety of video compression standards and computer hardware, network technology, all kinds of videos have begun showing explosive growth. Today diversity and network user terminal's own transmission characteristics, video transcoding become a new research hotspot...
A hybrid convolution tree kernel is applied to extract of the history evolution information. The hybrid kernel consists of two individual convolution kernels: a Path kernel, which captures predicate-argument link features, and a Constituent Structure kernel, which captures the syntactic structure features of arguments. The Predicate-Arguments Feature (PAF) kernel was extracted and decomposed into...
Functional size measurement is an important feature property of software metrics. As the core of software, algorithms are difficult to estimate due to different technologic methods and processing flows. This paper establishes the localization extension measurement principles on COSMIC-FFP FPA for complex algorithms and proposes function recognition principles, data group recognition principles and...
Video summary technology has become a hotspot of current researches. The application of sports video summary can quickly fetch important information in sports video that help sports enthusiasts and sports senior analysis the video. The present study takes tennis video as the research object. Firstly, determine the number of key frames based on statistical rules, and then extract key frames from different...
With the rapid development of CTI and VoIP technology, more and more attention is paid to the voice mailbox based on VoIP which is a kind of important telecom value-added service. In order to reduce the voice mailbox system development cost and shorten its development cycle, a solution of the voice mailbox system based on digital voice card and VoIP is put forward in this paper. This paper introduces...
With the rapid development of computer technology and application, the information system of power grid scale is more and more big. The relevant data of grid operation become more and more. The operator is facing all sorts of massive data and huge workload. Compared with the traditional form of text and charts, graphical display has irreplaceable advantages in readability, usability, appearance and...
Aiming at the defect that the current time dependent road network model cannot fully reflect the information of the road attribute, and considering that the road weights of traffic congestion factors should be based on the characterization of travel time and the impedance function model of average speed relations, we put forward the improved road network model which is based on the edge cost analysis;...
One main defect of current Markup languages is that they cannot cover the whole abstraction and UI generation procedures of descriptions with dialog control. Targeting on this problem, this work comes up with a new method which combing dialog control description and patterns. Starting from interface semantics, this paper gives definition and depiction of dialogue models in the UI patterns, then it...
Many computer science practitioners and software developers believes that the complexity of a program could be controlled more effectively by using object-oriented programming concepts. In addition to controlling complexity, the object-oriented approach allows faster development, reduction in costs, higher quality, easier maintenance, increased scalability, better information structures, and increased...
Using Laplace pyramid algorithm and pulse coupled neural network (PCNN), this paper proposed an effective fusion algorithm of multi-focus image. First, the paper uses Laplace pyramid for multi-scale decomposition of the image, and by using the PCNN to process the decomposition image, this obtains corresponding neuron ignition frequency map. Then, the paper calculates local entropy for every pixel's...
This paper presents an MVB signal capturer based on microcontrollers for metro train on-line health monitoring system. This signal capturer is of low cost and high power efficiency. The hardware of the on-board unit is built, and firmware for signal detection is designed.
Collaborative filtering algorithm is currently the most widely used and a very efficient technology in personalized recommendation system. To overcome several defects in the research of the traditional Item-based collaborative filtering algorithm, this paper presents a optimized algorithm in two aspects, which are the selection of neighbors and the prediction of ratings. Firstly, different numbers...
This paper designs and implements the bionic robot which is as an implementation of soldiers in the strategy game, and the robot has three parts: perception system, target and path system and decision-making system. The perception system is responsible for perceiving information inside the scene; the target and path system is to find the best position for attacking and the optimal path for the robot;...
It is effective to ensure the credibility of program to monitor the real-time status in the whole process when the program is been executed. Aiming at the problem of high convexity of feature extracting and interaction between false positive and false negative rate in current study, this paper proposed one kind of program behaviour model based on the dependencies. It constituted variable-length system...
In this paper a method is presented to extracts visual navigation baseline based on the processing image of farmland. Firstly, the weighted average method(2G-R-B) is used for processing original image. And improved Otsu is used to segment the gray scale image. Then the binary image of the division is denoised with small area method. The center points are identified of the denoised image, and points'...
In typical IP network, load balancing is adopt to enable the load of all servers approach a global optimal balanced by dynamically dispatching new flows to different servers in the network. Linux Virtual Server (LVS) plays an important role in the dispatching process. However, previous LVS-based researches have failed to consider expansibility, efficiency and security. Based on this, we proposed a...
