A new information hiding technology is proposed in this thesis. First, we designed a new image scrambling algorithm based on full array, then proposed a method for image information hiding based on image scrambling and least significant bit (LSB) technology. Some experiments show that the method is robustness, practical and has high efficiency in information hiding, it can achieve safe, efficient...
“Object-oriented programming” is one of the most important courses in computer science and engineering college, which has considerable difficulty not only in learning but also in teaching. The reform and innovation about the course are discussed, and the innovation projects for teaching content and teaching model are debated in this paper. In teaching process, the application of “Web-based Collaborative...
Data structure is the specialized core course for students majoring in computer science and technology, which has considerable difficulty not only in learning but also in teaching. Project-based learning (PBL) model is an important means for learning, it had been introduced to the curriculum in the past few years. We conducted project-based learning research and practice making full use of network...
Searching in complex networks is different from random and regular networks for existing long range connections and hub nodes. So the research on structure and characters of networks will improve the search speed and lower the load of nodes. Though getting the shortest paths is the best choice, in a real network, it is impossible for a node to get global information. For example, there is not a node...
Building hardware visual experiment environment (VEE) by software technic is an efficient way to improving the efficiency of computer hardware teaching and experiment design. This paper based on the computer principle & interface technology curriculum CAI, the concept and features of VEE is presented at first, and then some principles and tactics are summarized in building VEE. The implementation...
Software reuse technology can improve the efficiency of program development greatly. A reusable Apla-Java component has been developed in the research of PAR (Partition and Recur) method and their tools. We have made the most of reuse-driven software theory and the partial implementation theory for reference which ensure the accuracy of the components effectively. Apla-Java component is an important...
Revolution brings forth in information age. At the basis of "teaching model of project-oriented under tutor" which has been carried out successfully, we put forward a new teaching model fit for distance collaboration: teaching model-project-oriented and distance collaboration. In the paper, each teachingelement of the teaching model has been designed, which aim to realize the reasonable...
