Evaluating college teachers' professional level is a important link of teaching management and a important guarantee of improving teaching quality. This paper makes the college teachers' performance appraisal quantitative and determines the evaluation index from teaching attitude, teaching content, teaching method and teaching effect four aspects. The analytic hierarchy process (AHP) was used in performance...
Based on web interactive digital technology to exhibit the achievements of digital recovery for cultural heritage, it is better for the purpose of the dissemination of Chinese culture. In the three-dimensional virtual environment, the camera which could be independently controlled was added. Based on web interactive technology, character animation technology, collision detection and path planning,...
In this paper, we simply introduced the traditional decision support system and its characteristics and limitations. And then some new types of intelligent decision support system are recommended, such as GDSS, DDSS, 3IDSS and IDSSKD. And at last IDSS based on natural language understanding are described in detail. Some techniques and methods of IDSSNLU are introduced detailedly. The prospects of...
Mineralization is part of the geologic information, which makes it crucial to mine the geological anomaly from large numbers of data obtained from geologic exploration. Quantification of uncertainty in metallogenic prognosis is an important process to support decision making in mineral exploration. Degree of uncertainty can identify level of quality in the prediction. Rough set can directly aim at...
Traditional method of storing and querying XML documents is in single processor environment. The system performance deteriorates when the size of XML data sets increased. Parallel processing technology based on multi-processor is proposed in this paper. The key issues such as XML data model, storage model, data placement strategy, paralleling query, indexing etc. are also discussed.
We design and implement a cross-platform extendable Virtual Reality system with the MVC design pattern. It aims on cross-platform usage and extendibility which makes users to write VR applications much more easily. And the system can run on multiple platforms like Linux and Windows. To achieve extendibility, we embed the system with the Python script module which makes the system easy to be extended...
An adapting digital watermark algorithm based on the image fusion and chaos is put forward. The steps of the algorithm are: Firstly, the watermark image is pretreated in disorder using the chaos mapping. Then the NVF function of the carrier image is calculated. The strength of the watermark information is accommodated adaptively, and the watermark information is hidden in the carrier image by the...
Trusted Platform Module (TPM) provides the cryptographic functions through the Application Programming Interfaces (APIs). The specification of APIs reflects the security policies of the designers, in order to manage and protect the sensitive information of users, which is stored in the hardware module. But the security of these APIs has not guaranteed. In this paper, a formal model to describe the...
In this paper, we present a knowledge-based search engine that can assist ordinary users to search for medical information. User prefers to receive comprehensive, relevant information from the search results. An ordinary user is usually unfamiliar with medical background. We introduce a knowledge-based search which utilizes semantic knowledge to help understanding the documents. Medical concepts are...
