With the amount of data growing constantly and exponentially, the industry has encountered an unprecedented challenge of efficiently and reliably processing a tremendous amount of data. High performance computer has played a major role in the field of big data processing for its serious computational power and super-large storage. However, it remains some inevitable drawbacks to efficiently utilize...
As the clinical application grows, there is a rapid technical development of 3-D ultrasound imaging. Compared with 2-D ultrasound imaging, 3-D ultrasound imaging can provide improved qualitative and quantitative information for various clinical applications. In this paper, we proposed a novel tracking method for a freehand 3-D ultrasound imaging system with improved portability, reduced degree of...
In this paper, we propose a notion of contract signatures used in e-commerce applications. This scheme adopts digital multi-signature scheme in public-key cryptography to facilitate fair signature exchange over network. Security proof under the random oracle model of this modified signature scheme is include. This proposed solution allows two parties to produce and exchange two ambiguous signatures...
With the explosion of data growth, the problem how to retrieve information accurately and effectively comes into focus. To address this issue, researchers have put forward a variety of semantic retrieval models. This paper presents SDDP(Semantic, Density, Distance, Property) model which is an improved ontology-based semantic similarity calculation, and in this model the factors, such as semantic density,...
Driven by continuing scaling of Moore's law, computer system becomes more and more complicated. The Network application technology of the computer is a basic course in computer architecture. Computer assisted teaching system is used to make the students understand the Network application technology of the computer more easily. A multimedia teaching system is introduced in this paper. The system consists...
Computer organization and design course is one of the fundamental courses for computer science education. With the rapid progress in semi-conductor, new technologies in computer science are also emerging. It becomes more challenging for universities to design computer organization and design course. More new teaching methods and innovations are used to obtain better teaching effects as the corresponding...
Computer network has been in increasingly rapid development in recent years especially the prevalence of the Internet. The information exchange and transmission among the computers have become the inevitable trend in contemporary society. At the same time, information security also becomes the hot topic and is more significant in computer network. When the problems of information security are emerging,...
Computer organization and design has played an important role in the field of computer science and technology. With the rapid progress in semi-conductor, there are also new relative advances in computer science and technology. How to design computer organization and design course becomes more challengeable than before. The traditional teaching contents and the new advances should be organized together...
Computer organization course is the fundamental course in computer science and engineering. It is also the core course of the undergraduate degree program of College of Computer Science at Zhejiang University. It is important that how to provide supplementary teaching resources and methods to improve the teaching effect. In this paper, we present a Top-Down and Bottom-Up blended teaching model and...
The rapid progress in information and communication technologies has made the Internet be widely used in our daily life and many other fields. The virtual society is based on the Internet and it is also a problem to the labour union under such environment. Electronic labour union will improve the efficiency of the union and help the members to communication with each other. But it is a challengeable...
One design method of 32 bits comparator for multi-number systems was proposed. In this method, 64 bits double precision floating point data and 32 bits single precision floating point data based on IEEE754 standard, 32 bits signed fixed point data and 32 bits unsigned fixed point data can be processed by the same comparator. An RTL module was implemented based on the proposed method. This RTL module...
Embedded system education is an enormous challenge for the universities because embedded system is at the intersection of different disciplines and in continuous rapid progress. Outstanding curriculum design of embedded system will keep students close to the requirements from industry. In this paper, we share our experiences in how to promote embedded system education by student technology club. This...
With the development of computer science and technology, computer applications are gradually turning to structure design from code design. In order to improve computer performance and enhance the application level of computer architecture in software engineering, the college of Computer Science and Technology in Zhejiang University has proposed a teaching reform idea, in which Digital Logic, Computer...
