The paper proposes the framework, modules, design and implementation of thesis management system based on specific thesis management mode. The system uses ASP.NET as front development tool, SQL Server 2005 as the background database tool, and based on B/S structure. The system includes these features, teachers submitting topics online, students selecting topics online, exchanges of teachers and students...
CATIA, as the main design software of the flight simulator display system, can complete the structure design of display system; find the rationality of structure design by the virtual assembly; do some appropriate changes to achieve the optimal solution.
Experiment teaching or research can't be carried out on schedule at some schools and research institutions due to the lack of sufficient experiment instruments or other reasons. Virtual experiment technology could resolve the problem effectively, and would play an increasingly prominent role in modern teaching. This project designed and accomplished a series of aerodynamics virtual experiment software...
Aiming at the current situation of hydrological monitoring, integrating with the application of internet of things in hydrological monitoring area, to realize automation of hydrological monitoring, the system for hydrologie monitoring based on internet of things is designed. This system is constructed with internet of things technology, software technology, evaluated network technology, etc. The system...
Compared with traditional guard management, this system uses radio frequency identification technology (RFID) to achieve intelligent access management. When need identification, RFID reader issues a fixed frequency radio. Then label card is stimulated, and returns ID number. By ID number and database information, we have developed a lot of access control management functions, such as staff automatic...
The paper begins with discussion on Aspect-Oriented programming (AOP), including its concept, thought, development, and advantage in handling crosscutting concerns, followed by description of the theory of constraints. Furthermore, combined AOP with first-order logic language, a new method to detect the business constraints in requirement analysis is presented, which is simple and practicable, thus...
The software radio technology has get an increasingly wide application in the communication field because of its open structure and the comprehensive programmability, its signal processing usually use the design method of DSP and FPGA unifies. This method also suits in the design of radar which structure similar with SDR, some companies and the development facilities have conducted this technology...
This paper implements a PLC(programmable logic controller) based virtual instrument that performs measure and control in mechanical characteristics test for flow control throttle in gas pipeline. The development of the instrument is based on PLC and LabVIEW IDE, which features a novel combination of leading industrial control tools to construct the virtual instrument. Since OPC(OLE for process control)...
The article introduces the object-oriented design and the inclusive software module, detailed about the software development process. The software has maintainability, expandability, portability.
By using 10 groups of training data which were collected through testing a cellphone in order to find the overall functions in it, a size estimation model was built by using Mathematics, a tool to help implement a fitting method for the parameters in COCOMO model. By invoking the FindFit function and using the least square method, the parameters were fixed. With two groups of test data, the size estimation...
With the energy crisis and environmental pollution becoming more and more serious, the traditional fuel vehicles have exposed many shortcomings. Electric vehicles gradually became the focus attention of both governments and car manufacturers, and the popularity of electric vehicles will be the inevitable trend of social development, so the electric vehicles charging station will become indispensable...
For real-time environmental monitoring of air quality to design the system, use the virtual instrument test software LabVIEW to achieve real-time monitoring of pollutant gases, With database access toolkit to access Access database for LabSQL, display the Real time monitoring data and trends, Environmental monitoring personnel Customized monitoring time and data storage time based on actual conditions,...
The status of the remote monitor system is introduced and the composing and the principle of implement of the system are presented. Based on it, the function and the characteristic and each of modules of software and database design are introduced too. The system improves the performance and stability of supply power and reduces the times of power cut, it can forecast the possible fault through analyze...
As to the research on AspectJ in this context, after analyzing the Java program, AspectJ can realize the capture of the join points based on the Boolean or Compound expression in the Java program. The information includes: the time to judge the runtime condition of each join point as “true” use of the logic AND (&&) to combine pointcuts; and use of the logic OR (‖) to combine pointcuts; all...
To solve the problem of prediction accurately cost in software cost estimation, a new method of software project life cycle cost estimate algorithms was proposed, based on Fuzzy rules dealt with multi-level discrete neural network structure and HCM clustering algorithms. A new software projects were divided into two apart: with similarity and without similarity. For the cost of former, fuzzy clustering...
Grid technology provides great opportunity and challenge for education informationize. Grid technology can resolve the problems in existing e-learning platforms and provide more help for further development of e-learning, especially in creating better collaboration environment. Computer-supported collaborative learning (CSCL) based on grid technology was discussed in the paper. Grid computing can...
This paper introduces the way to abstract method execution and constructor information after researching basic information needed in reversing-engineer by AspectJ. AspectJ, which is one of concrete realization of AOP, can analyzes Java-procedure. We abstract basic information including not only three aspects: calls, returns and returned values, but also method execution and constructor information.
HLA (High Level Architecture) has been widely applied distributed interactive simulation field, and RTI (RunTime Infrastructure) is the supporting environment for HLA running and is distributed software system. HLA does not specify its realization. Up to now, there are different RTI release versions with different levels of functions and performances. To ensure selected RTI to satisfy simulation application...
Through the analysis of major fatal accidents occurring in China's coal mines, it showed that human errors account up to 96.5% for total causes. Therefore, in order to prevent the miners' unsafe behavior and accidents analyze the factors of unsafe behaviors with the object study of G mine's N1301 face's miners, and determine a factors' set which consists of 4 first-level factors and 16 second-level...
In order to obtain the mechanical characteristics of high voltage circute breakers, an embedded microprocessor is properly used in the monitroing device, that is described in the paper. The mechanical characteristics of high voltage circuit breakers are monitored through long-term recording the signal during the operation. The data recorded are utilized for diagnoseing fault and may be employed in...
