To solve the problem of limited energy and to get CTD data real-time display with easy operation, the paper gives a brief design of remote power supplied CTD real-time monitoring system and its detailed software design. Finally, the paper gives the test result which proves that the system can...
Modern avionics architecture is evolving from traditional federated architecture to Integrated Modular Avionics (IMA) architecture. ARINC653 standard, which is employed in the avionics industry, supports partitioning core concept in IMA. Furthermore, avionic software has very high safety and reliability requirements in safety- critical domains. Therefore, how to develop high-integrity avionics software...
The method offers a way to count piled thin steel plate for car chassis based on digital image processing and software designed for it. First enhance the photo of the piled steel plates. Then after acquiring the region of interest (ROI) and detecting the lines, horizontally shear the image against the tilting angle to adjust to vertical. Finally, count the number of plates in a picture by counting...
XBRL is the latest technology used in processing accounting information. The core part of XBRL is the creation and application of taxonomy. XBRL taxonomy engineering is a special case of software engineering. From the software engineering perspective, the result of the design phase in XBRL taxonomy is the metadata model and the result of the building phase is XBRL element definition converted from...
As semiconductor technology scales into deep submicron regime, transient fault vulnerability of both combinational logic and sequential logic increase rapidly. It is predicted that in 2011 transient fault rate of combinational logic will overtake that of sequential logic in processor. In this paper, particle radiation-induced multi-bit transient faults in decoder unit, representative combinational...
Avionics software is safe-critical embedded software and its architecture is evolving from traditional federated architectures to Integrated Modular Avionics (IMA) to improve resource usability. ARINC653, as a standard widely employed in the avionics industry, supports partitioning concepts in accordance with the IMA philosophy. To insure the development of the avionics software constructed on ARINC653...
Following with the charting process of risk map, the paper designed and developed Risk Mapping Tool (RMT), which is based on Microsoft .Net platform and SuperMap 5.3 COM. RMT encapsulates seven modules, including Risk Mapping, Cartographic Generalization, Making Thematic Map, Map Sheet Management, Risk Map Database, Vector Data Analysis and Raster Data Analysis.

The geomagnetically-induced currents (GIC) on the power grid results from changes of geomagnetic field caused by solar activity, which is the significant problem and needs to be monitored to provide data for disaster analysis. In this paper, we combine with computer networks and communication technologies; develop the Web-based monitoring system for geomagnetically-induced current. The system's background...
The magnetic field fluctuations in the power grid will produce geomagnetic induced currents (GIC) when magnetic storm occurs. Monitoring and analysis of the GIC is an important new task. At present, although the domestic GIC monitoring devices can monitor GIC, they are unfavorable for installation for their large size and weight. This paper proposes a GIC monitoring model which is based on embedded...

And analysis the application of each intelligent control theory such as Cybernetics and Information theory, also technology such as Sensor and automatic detection, Microelectronics...
Software as a service (SaaS) is a new style mode of software deployment whereby a provider licenses an application to customers for use as a service on demand, and it challenges the traditional software mode and makes major changes for IT organizations to deploy application. Incidents are recognized as service disruptions which can have a considerable impact on business capability of IT organizations,...
Agile software development methods are widely used globally, especially in building information systems for enterprises. Software developing vendors are suppliers in an informationalization supply chain (ISC) of the customer. To analysis the impact of agile software development on the management of ISC, firstly a brief introduction of agile software development methods is presented. After that the...
A new fragile watermarking algorithm for software configuration management is proposed in this paper. Firstly, the program (cover work) is divided into N groups, and hash function is used respectively to obtain the whole program information. Secondly, the watermark is obtained by combining with program information, author information and time information. The software version index (similar to software...
A new fragile blind watermarking algorithm for content authentication is proposed in this paper. Firstly, the program (cover work) is divided into segments according to the three basic program control structures (sequence, branch and loop). Secondly, the frangibility of watermark is used to mark the variation of the code line, which achieved through using a hash function and generalized character...
