The global open source software resources have become an Internet-scale repository, which provide abundant resources for software reuse. However, how to locate the desired resource efficiently and accurately from such large amounts is quite a challenge problem. Most of recent works barely focus on the semantic similarity by analyzing the software itself, which often result in inappropriate ranking...
The use of sub-millimeter wave radiometer on the geostationary orbit meteorological satellite is of great significance to the study of the Earth's atmosphere. This paper presents a single-channel quasi-optical network system around 325GHz. The diffracted Gaussian beam analysis method (DGBA) and a three dimensional visual software based on it are used. This design is used in the sub-millimeter radiometer...
Text data hiding is a steganographic technique different from the secrets hiding in multimedia, such as images, audio and video. Sun et al. proposed a text data hiding scheme to divide the Chinese character into left and right parts for enhancing the capacity, which is called L-R scheme. Adopting the concepts of Sun et al.¡¦s scheme, Wang et al. proposed an improved version to incorporate the up and...
With the constantly advance of IT in education, the interactive learning based on social software carries an important influence on personalized learning, independent learning and collaborative learning. Constructivist learning theory has laid a theoretical foundation for the interactive learning based on social software. The paper discusses the meanings, characteristics, classifications on the social...
The great appliance of engineering makes it different from other common subjects in teaching methods. This paper puts forward a concept of case learning that is constructed with projects and a corresponding case learning system based on project is designed and attained, which is believed to bring a new way for the future teaching of engineering.
When designing the solar power generation system is in face of the variety of solar cell, the user must consider not only the needs of the load and also the price of the solar cell, weight, annual power generating capacity (APGC) and the maximum power. It is an important task to find the optimal power generation system with many parameters. Therefore, this paper presents an estimation method based...
P2P trust systems are essential to against the selfish, dishonest, and malicious peer behaviors. But most previous trust strategies of P2P network have many defaults such as low accuracy, high traffic etc in trust decision. Then we proposed a structured trust P2P network based on DHT (discrete hash table), in which includes peer management and peer locations based on the DHT circle, another, a top-n...
