Semantic Web Service Selection Algorithm Based on QoS Ontology

To satisfy users personalized requirements of Quality of Service (QoS) better when they select services, a selection algorithm based on QoS ontology which can describe and measure QoS heterogeneous parameters is proposed in this paper. The most adaptive services are selected though the process in this algorithm. With a simulating system implemented and evaluated by experiments, the feasibility and effectiveness of this algorithm is proved. And the results show, the most adaptive services can be selected easily and the user satisfaction degree is higher with this approach.

Temperature monitoring based on image processing for intelligent microwave heating

Microwave, as a clean and efficient energy, can solve growing levels of pollution and energy problems. But In the process of industrial production, the use of high-power microwave will cause hot spots, thermal runaway, or even explode. Therefore we need to achieve intelligent control of microwave, to ensure the safe and efficient use of microwave energy. Accurate temperature information is the basis for intelligent control, and there are many methods to monitor temperature in microwave oven, for example, optical fiber and infrared temperature measurement and ultrasonic thermometry. But these methods suffer from high attrition rate locality, or difficulty in installation problems. To solve the problems, we propose a temperature monitoring approach using image processing and colorimetric technique. To evaluate the proposed approach, we established a microwave heating system with camera and fiber, developed temperature measurement software to monitor temperature, and visualized the temperature field for the heating object in the microwave oven. The experiments show that the proposed approach is non-contact with low cost, easy to installation, and accurate on the reconstruction of temperature field.

Study of Progressive Training Plan on Software Engineering Talents

Software engineering talents training is the foundation of the development of Chinese software industry. This article demonstrates the software training goals for undergraduate students in the school of software engineering of Chongqing University, and put forwards the software talents training program based on progressive practice teaching system. Through a series of integrated courses on project practice and training, the program aims to cultivate software engineering talents of “compound, application—oriented, international” characteristics to meet the development of Chinese software industry.
