An extranet in action: Globally networked academics and students

The vexed issue of keeping staff and students up-to-date in the fast moving world of internetworking has been exercising the minds of many tertiary institutions for several years. One Australian Faculty of IT has partnered with industry in an attempt to keep the course materials up-to-date and relevant. This has led to major changes in the culture of the faculty as staff too have been trained in the certification subjects and must pass rigorous industry level examinations in order to be qualified to teach the material. This paper describes the programs and reports as well on the results of student surveys which were undertaken to see if the policy was meeting the needs of the students. The paper refers to previous staff surveys as well

Replicated shared object model for parallel edge detection algorithm based on spiral architecture

Edge detection in computer vision and image processing is a process which detects one kind of significant feature in an image that appears as discontinuities in intensities. A parallel edge detection algorithm based on spiral architecture is designed in this paper using a replicated shared object model (RSOM). We use this approach to meet the requirements of replicated object management, update propagation, underlying communication and consistency maintenance among replicated objects. Multi-scale image theory plays an important role in this research. © 1998 Elsevier Science B. V. All rights reserved
