In this paper the equation with periodical condition and small parameter is considered. The equation will lose boundary condition and lead to large oscillation in boundary layer. The properties of the equation is studied firstly. The analytical solution is decomposed into the smooth component and the singular component. The asymptotic solution is proposed secondly. The asymptotic solution is used...
More and more smart systems have been used in modern household. This article mainly introduces the smart household control system realization procedure based on DTMF remote transmission. The system used AVR SCM to dispose and exchange information. We realized household appliances remote control by communication through mobile telephone and GSM card of the system host computer TC35i by DTMF signals...
A scheme of segmentation based on low-level and high-level cues is presented. Firstly, image-pyramid is obtained based on segmentation by Weighted Aggregation (SWA), the suitable coarse pixel image is selected to be as low-level segmentation cues. Kernel principal component analysis (KPCA) is used for building the space of shape to represent shape prior knowledge. The coarse pixel image is expressed...
The structures approximation analysis technology is studied based on neural network. The back-propagation neural network model corresponding to the size parameters of the hydraulic press' crossbeam and its displacement or stress is generated to replace the original finite element model in this paper. Using the saturated multi-level table of orthogonal arrays to choose the trained samples could make...
Facing solely demand uncertainty of market, a supplier with insufficient capital doesn't like to enter the market because of risk of the market. The supplier looks forward to choosing a retailer with sufficient capital as his partner to share the risk of market. Based on dynamic game, we demonstrate that both the supplier and the retailer's expected profit are positive when reaching Nash equilibrium...
A new solution to vehicle routing problem (VRP) is proposed in order to overcome the disadvantages that the exact algorithms and heuristics algorithms are difficult to solve vehicle routing problem with multiple constraints. A simulation model of vehicle routing problem is built by combining the object-oriented technology and discrete event simulation technology. In this model, the events of distribution...
The method of surface geometry of object recovery mentioned in this paper can gain 3D dimensions of objects surface geometry only using a single image on the basis of brightness change. In this paper, the background knowledge and the methods related to SFS are briefly introduced. Based on the analysis and comparison of various reconstruction algorithms, this paper gives a new method of surface geometry...
Autonomous underwater vehicle (AUV) has been widely used in marine exploration and military applications in the past decade. The Decision-making Control System of AUV plays a key role of accomplishing its tasks in complex undersea environment. In this work a Behavior-Based Reactive Decision-making Control System is proposed for AUV. During the design of the Decision-making Control system, the hierarchy...
This paper presents a novel and efficient algorithm for preventing the block wrongly matching in image inpainting. The proposed technique separates the inpainting process into two different and important steps. First, segment the pre-selected source area, which is called the source region, from the input image. This step can prevent the block wrongly matching effectively. Besides, the adjustment rule...
In order to achieve seamless handover for real-time applications in the IP Multimedia Subsystem (IMS) of the next-generation network, a multi-protocol combined handover mechanism is proposed. In this work, we combine SIP (Session Initiation Protocol), FMIP (Fast Mobile IPv6 Protocol) and MIH (Media Independent Handover) protocols by cross-layer design and optimize these protocols' signaling flows...
This paper employs Genetic Programming (GP) with individuals of tree structure to form empirical formulas in order to track the dynamic pattern of the moving average curves of stock prices. We find that our method tracks the 60-day moving average better than other shorter period averages. In order to minimize the effects of noise and other random events impacting on the markets and maximize the effective...
A novel locating vehicle license plate (VLP) method is proposed in this paper. Firstly, preprocessing is used on the license image. Then a series of morphological operations are used to extract important contrast features to find out all license plates candidates. As a result of the noise, more than one candidate will be extracted after the morphological operations, so the auto -correlation based...
Based on the PID(Proportional-Integral-Differential) control algorithm, by analyzing the control system with control variable varying in the form of arbitrary function, a simple control method with control variable varying in the form of arbitrary function was presented, i.e. PID control algorithm with set value which is constant in small zone. The paper introduced the mathematical model and the parameter...
Grouplet transform (GT) can take advantage of the image's geometry structure since the bases of Grouplet can adapt the different geometry structure in different scales. The association fields that calculate by The Block Matching algorithm which cannot adaptive to different textures cannot follow the turbulent texture contained in an image. Grouplet transform based on Streamline (GTS) introduced streamline...
A conceptual modeling of an adaptive or a flexible learning content management (LCM) system is an initialized step toward successful implement of a distance education system on Internet. Its aim is at planning and accomplishing the responsiveness to the learning content (re)configuration required for meeting the students' learning goals. Since learning content is composed of the relative learning...
