Network on a chip(NOC) is a new kind of communication method on a chip, which is evolved from system on a chip(SOC), learning from computer network. It is an important component of the multi-core technology. The network on a chip provides a new way to communicate, and it performs better than the original system on a chip based on bus. As the size of system on a chip expanded, the number of nodes in...
One of the mainstream research fields in learning from empirical data by support vector machines (SVM) is an implementation of the incremental learning schemes when the training dataset is huge. Moreover, the challenge of applying incremental SVMs on huge data sets comes from the fact that the amount of computer memory and learning time required along with the amount of dataset increased. In this...
IPv6, as the protocol of future generation, has many advantages in constructing home information network. This paper proposes construction of a kind of home information network based on IPv6 protocol and discusses prototype design. This construction has expansibility and practicability with simple operation, and collocation and many advantages in constructing IPv6 home information network.
In RBAC model, a user cannot obtain part permissions of a role, and a role cannot inherit part permissions of another role. The set of permissions cannot be obtained EPSET1 and the set of permissions cannot be inherited EPSET2 are introduced, a fine-grained access control based on RBAC model is proposed in this paper. The algorithms for solving the set of permissions belongs to a role or a user are...
A new experimental teaching system for computer graphical course was presented. In the system, the students may design programs about graphical methods and submit the experimental data and pictures to database. The system may automatically grade results about students' experiment. The teacher can use handmade perusal. The system can not only educate students' ability of study and design, but also...
Research and development of sample wheel control system are one of the key technologies in atomic force microscopy (AFM) of deep space exploration. Small size, light weight and low power consumption are realized in modular design at the electric control system of Sample wheel. Using the AVR ATmega16 processor, the module communicates with the industrial motherboard of AFM scanner through the RS232...
With a view to keeping up with the new development of higher education, university computer teaching should also continue to improve teaching methods and means. After several years of university computer teaching practice, summed up ldquo6-Usingrdquo mode. This teaching mode shows that teachers and students in teaching activities are interaction, complementation and mutual assistance. It is also to...
