Computer programming skill is the basic ability of undergraduate in computer major. It is very worth exploring how to improve the ability of college students to programming. Based on our teaching practice in this area, we find that open laboratory which centers on small-scale project development is very good approach. In the paper, first, we discuss the approach in detail. Then, from a few aspects,...
Although WSDL and UDDI are widely accepted as standards for web service discovery, they can not guarantee scalable, flexible and automatic service discovery. Therefore, Semantic Web Services (SWS) is proposed to ensure high-quality service discovery. However, an effective and dedicated semantic registry for SWS discovery is still desired. Accordingly, in the paper we propose an approach and implement...
Although WSDL and UDDI are widely accepted as standards for web service discovery, they can not guarantee scalable, flexible, robust and automatic service discovery, since WSDL and UDDI are syntax-based and centralized approach. Therefore, integrating with previous work, we propose an approach to distributed SWS discovery based on Chord and SWS technology. First, we present previous work in the paper...
Chinese Character Recognition generally does its best to identify a handwritten Chinese character. It seldom cares about normativity of writings. In the paper, we propose an on-line evaluation approach to normativity of Chinese character writing, which is based on position vector of strokes of character writing. The approach can find whether or not the order and location of strokes of character writing...
Due to the complexity of the path planning for tourist scenic area, we divide the path of Tourist Scenic Area into panoramic scenic graph and sub-scenic graph, and regard these graphs as the same problem to solve. The paper puts forward the improved ant colony algorithm, and designs breeding ants, visual ants and common ants, which travel by their own rules. When the ants travel all the scenic spots,...
Although WSDL and UDDI are widely accepted as standards for web service discovery, they can not guarantee scalable, flexible, robust and automatic service discovery. Therefore, integrating with previous work, we design an approach and implement it for distributed SWS discovery based on P2P and Semantic Web Service technology. In the paper, first, we present the basic idea on which our approach in...
Semantic Web Services (SWS) is proposed to ensure Web Service core missions automation, nevertheless, a dedicated Web Service discovery technology based on SWS is desired currently. For this reason, we propose an effective SWS matching algorithm to achieve service discovery based on semantics. In the paper, we first refine core properties and requirements to apply subsumption relation to involved...
In previous work, we propose several mechanisms for distributed SWS publication and discovery. As same as some other applications of Semantic Web, they require users to provide concepts which are defined in domain ontology. However, users usually can not give an exact concept defined in ontology for a word in an open environment. For the reason, we propose a distributed ontology publication approach,...
As one of the main purposes, Semantic Web Services (SWS) is proposed to ensure automatic service discovery. However, an effective and dedicated semantic registry for SWS discovery is still desired. Therefore, we propose a mechanism and implement it as prototype for SWS discovery. In the paper, first, we discuss the architecture of the mechanism and its properties as a prototype. Next, design an SWS...
In the paper, we analyze the shortages of service-oriented analysis and design (SOAD) methodologies, and then review the features of data flow diagram as a kind of requirement analysis technology. Finally, we propose an SOAD method using DFD diagram. Therefore, a process is provided as a guideline to aid analyst to accomplish high-quality service identification with the method. Through an illustration...
A control system design of a new explosive ordnance disposal (EOD) robot based on the binocular stereo vision location is presented in this paper. The principle of the binocular vision location and the design of a motion control system are described. Real-time control system of the robot based on xPC target through the Matlab/RTW method run successfully in test prototype furnished with PC/104, and...
Nowadays, the existing EOD robots usually are operated manually; it is very hard to operate. According to the theory of stereo vision, a new explosive ordnance disposal (EOD) robot with a binocular vision system is developed. The vision system captures real-time images, makes camera calibrations with Zhang's method, preprocesses images, matches feature point, then gets the stereo coordinate of the...
