This paper is concerned with the developing technique and the pattern of multimedia CAI(Computer Aided Instruction). The process involves educational psychology, computer science, experts system and artificial intelligence. The computer is mainly used to show teaching goal and content; note students’ studying status or control the studying schedule. All steps through teaching must be true of the pedagogical theory and technique; involve multimedia computer technology and modern instructional theory. Therefore, we can accomplish teaching assignment with high efficiency. This paper can play an important role on the design of this kind of software.

An intelligent control system of the abrasive waterjet cutting machine is designed based on ARM9 and &µ C/OS-I I. The input signals (thickness of the workpiece, abrasive flow, surface roughness, pressure of abrasive water-jet) are received by the control system and dealt with by the fuzzy neural network and embedded kernel of ARM9. Then it provides the drive signals of AC servo motor to realize the speed of compensation. Finally, the machine can run rapidly and steadily to achieve the goal of the quality. The experimental results prove that the control system has certain stability and can reach the cutting accuracy.

The majority of independent college has only been less than a decade since it is established. There are many deficiencies in teaching management, the target for training talents and overall quality of students, etc. Therefore, the graduates of computer science of independent college are usually in a disadvantageous position when they compete with the skilled personnel trained by higher vocational schools, and the application-oriented talents trained by research and teaching-oriented colleges and universities for finding a job. To solve it, this paper firstly presents status and difficulties in developing application-oriented abilities of students. And the main related factors for training application-oriented talents are introduced. Then, the model for training application-oriented talents which integrates the ways of learning by doing and cooperative learning is proposed. Last, the difficulties, countermeasures and practical effects for this model are presented. The results show that this model could be better to train application-oriented talents of independent college.

Soundness is a vital property of Interorganizational Logical Workflow Nets (ILWN) which can efficiently model cooperative systems. But even though each logical workflow net(LWN) is sound, soundness of arbitrary ILWN is hard to decide. This study analyzes the causes of leading to deadlocks of interface transitions and unboundedness of interface data places: the incorrect order of transitions related to interface data places, conditional routing construct and accumulation of tokens in interface data places. Based on the analysis, this paper defines the concept of T-fair LWNs and proposes an important subclass of ILWNs: T-fair ILWNs. For T-fair ILWNs, this study presents the inheritable conditions of soundness and gives a rigorous analysis approach according to their static net structures only. And then an approach of verifying the soundness of ILWNs composed of n T-fair LWNs is proposed. The concepts and techniques proposed in this study are illustrated with a useful example: an online bookstore and customer system. In addition, This paper discusses some cases which have fewer requirements for interface data. Based on that, a rather simple criteria condition is provided for T-fair ILWNs which are marked by restricted logical expressions.
