this paper examines the role of Human computer Interaction in the context of the computer Science and softwareengineering curricula. We suggest there needs to be much more integration between computer Science and HCI. We believe this can be brought about by adopting HCI as the underlying principle to the development of systems. Usability engineering would provide the necessary framework for the development of usable systems.
Understanding the interactions between hardware and soft-ware is important to performance in many systems found in data com-munications like routers. Responsibilities that traditionally were pro-grammed in software ar...

In recent years, agent technology has been used increasingly in information management and distributed computing. A CSE curriculum that cultivates the knowledge of agent technology will increase the likelihood that the next generation of IT professionals have the background needed to design and develop softwaresystemsthat are scalable, reliable, adaptable, and secure. In this paper, we present the rationale and our practice in incorporating agent technology into the CSE curriculum. We develop agent-based teaching materials and software modules and apply them to existing CSE courses including artificial intelligence, parallel and distributed processing, networking, and softwareengineering. Promising results have been obtained in teaching two graduate level courses using agent components.

the travelling salesman problem, which can be solved with various methods, is a traditional and typical problem in artificial intelligence (AI). As an evolution of Petri nets, colored Petri nets (CPN) can be dedicated to modeling and analysis of different systems as a new attempt. the paper shows the brief description of the given problem and CPN, we detail the implementation of the CPN model of the problem and analyze the simulation result. this CPN example shows the potentiality of CPN application in AI.

Embedded systems are often designed by experienced designers by interfacing appropriate programmable components to a microprocessor to meet particular design requirements. However, during automated synthesis of these systems, reuse of programmable components hardly takes place. the primary reason is the lack of algorithms that can perform component adaptation like a human designer. In this paper, we present an algorithm based on a new simulation relation called forced simulation to perform automatic component adaptation to match the component to a specific design function. We illustrate the algorithm by adapting Intel's programmable interval timer to behave as an interrupt on terminal count function.

the National Classroom Project (NCP) is exploring the effective use of in-class palm computers and Internet technology to enhance student learning in grades K-12 through college. the paper discusses lessons learned from three years of practical experience both on a college campus and in 5th and 9th grade classrooms in the local school district. Topics covered include technology and software in addition to classroom observations.

the study of image compression has been risen dramatically. Many new ideas have come out with impressive results. Since images can be regarded as two-dimensional signals withthe independent variables being the coordinates of two-dimensional space, many digital compression techniques can be extended, for instance from one-dimensional signals. this paper presents the most used still and video image compression techniques.

the StrongARM SA-1100 is a high-speed low-power processor aimed at embedded and portable applications. Its architecture features virtual caches and TLBs which are not tagged by an address-space identifier. Consequently, context switches on that processor are potentially very expensive, as they may require complete flushes of TLBs and caches. this paper presents the design of an address-space management technique for the StrongARM which minimises TLB and cache flushes and thus context switching costs. the basic idea is to implement the top-level of the (hardware-walked) page-table as a cache for page directory entries for different address spaces. this allows switching address spaces with minimal overhead as long as the working sets do not overlap. For small (/spl les/32 MB) address spaces further improvements are possible by making use of the StrongARM's re-mapping facility. Our technique is discussed in the context of the LA microkernel in which it will be implemented.
