Using chalk is not only laborious, but it also produces a lot of chalk dust, polluting the air and adversely affecting the health of the students and teachers. This design uses ARM9 board for hand-held terminal hardware and uC/OS-II embedded real time operating system for hand-held terminal software. When teacher writes on a book-size touch screen with an electrical pen, handwriting signal will be...
This paper firstly examines the traditional vehicle styling evaluation methods and issues, and then presents a new approach which uses ANN (artificial neural network) to build an expert system for bus styling evaluation. It describes the key technical issues of quasi-three-dimensional bus styling evaluation expert system from data collection, graphical pre-processing, graphics feature extraction,...
With the rapid development of embedded industry, the performance of operating system in embedded equipment has been more and more attended. And according to embedded system characteristics, this paper uses a form of improvement and expansion to design a kernel operating system suitable for multi-core embedded platform, so that to promote the in-depth application of the multi-core processor in embedded...
Human is able to cluster and filter object efficiently. Clustering problem has been approached from diverse domains of knowledge like graph theory, statistics, artificial neural network and so on. There has been growing interest in studying combinatorial optimization problems by clustering approach, with a special emphasis on the Euclidean Traveling Salesman Problem. Classical ETSP appears as a fundamental...
Nowadays, many industries use the Computerized Numerical Control (CNC) for Printed Circuit Board (PCB) drilling machines in industrial operations. It takes a long time to find optimal tour for large number of nodes (up to thousands). To achieve more effective results, optimization systems approach is required to be equipped in drilling machine. Euclidean Traveling Salesman Problem (TSP) is one of...
The paper explores the methods on decision of optimal strategy for online maintenance for Internetware through static Game Theory. An Online Maintenance Game Model (OMGM) is put forward, which simulating the trend of consuming resource and involving the dependent relationship and characteristics of the procedure maintenance among fault Internetwares. In the case of single fault Internetware and double...
Points out the obvious deficiencies in capture/playback mechanism at present, aiming at difficulties of maintenance and extension in constantly altered GUI elements, presents a new GUI automation testing solution - Building AUILibrary. It can search, identify all the controls, trigger all kinds of mouse and keyboard events, execute data driving verification roundly and accurately, trace and record...
With the extensive application of GNSS (Global Navigation Satellite System) around the world, the technology of global navigation and orientation technology has run to a brand-new stage. With the development and improvement of China's Beidou and Russia's GLONASS system, and the application of the multi-band and multi-mode navigation satellite receiver will be the hotpot of the research and application...
Software security has become a crucial component of software systems in today's market. However, software security development is still a maturing process. In this paper, we present an approach for assessing software architecture to determine how well it can satisfy intended security requirements. It is important to be able to assess the security of software under development at an early stage (e...
In order to provide a more relaxing environment where the dental students can learn to memorize the fundamental knowledge as well as the processes and techniques in dental casting, we used the GBL concept as the basis to construct a system model. We had taken the process of dental lost-wax casting and integrated through gaming, the theories and practical skills in the dental casting course, to create...
The computational complexity of H.264 video coding standard is two or three times higher than that of H.263 and MPEG-4. Especially, the operations of the entropy coding and deblocking filter are the most complex parts in the decoder. In order to reduce the computational complexity of these operations, we propose a fast algorithm for H.264 decoder implementation, which containing a group-based CAVLC...
Earlier programs designed for Quantification theories do not run in a Windows environment, do not allow inputting parameters directly. To actualize the quantitative prediction algorithms independent of the DOS environment, the authors develop Quantification Theories software (QT software), by Fortran language programming method. The QT software is presently the only software in China, which is independent...
Due to the problem of complex relation between different data types existing in information model of fault tree diagnosis, the modeling method for information model of fault tree diagnosis based on UML is proposed. Firstly, the requirement of integrated diagnosis and AI-ESTATE to information in test and diagnostic environment and the shortage of information model of fault tree diagnosis is analyzed...
Voting algorithms are used in a wide area of control systems from real-time and safety-critical control systems to pattern recognition, image processing and human organization systems in order to arbitrating among redundant results of processing in redundant hardware modules or software versions. From a point of view, voting algorithms can be categorized to agreement-based voters like plurality and...
This paper provides a solution for ERP software selection & elimination. ERP is a way to integrate data and processes of an organization into a centralized system that aims to have a single software solution where the information needed for decision making is shared across different departments. The selection or elimination of technology is a multi-criteria, multi-attribute, decision making problem,...
This paper analyzed the definition of software testability and its effect on software reliability test set. The conception of test effectiveness was proposed and the quantity model of minimal sample size in the software reliability demonstration testing (SRDT) introduced test effectiveness was put forward. Then the difference between the number of test cases with different test effectiveness was compared...
An evaluation model of plastic forming process and forming quality of metal tubes is proposed by considering restrictions of manufacturing resource, geometry and forming quality. Three key technologies including evaluation index system, modeling of evaluation knowledge and evaluation workflow are studied in detail. Simulation method of bending process is introduced to study the machining character...
In this paper, we identify and analyze a set of characteristics that increasingly distinguish today's complex software systems from “traditional” ones. Several examples in different areas show that these characteristics are not limited to a few application domains but are widespread. Then, we discuss how these characteristics are likely to impact dramatically the very way software systems are modeled...
The software of on-line acquisition system for infrared drying process is designed. Sample mass and temperatures of heater and sample corresponding to voltage values are obtained by function transformation based on VB6.0 procedures. The change curves of drying rate, radiation temperature and sample temperature are generated, and then shown on VB interface directly. In the design process, anti-interference...
