A new technique for manufacturing microelectrode arrays is described and assessed. This technique uses wire Electrical Discharge Machining (wire EDM) to form detailed array structures from a single sample of solid metal. Chemical etching can then be used to increase the electrode aspect ratios. Electrode lengths of 5 mm, widths of 40 μm, and spacings of 250 μm have been fabricated using this technique. Arrays of electrodes of varying lengths can also be fabricated. For intracortical recording applications, the signal paths are isolated from one another by securing an insulating substrate.
The application of Hough Transform (HT) has been limited to small-size images for a long time. For large-size images, the peak detection and the line verification become much more time-consuming. Many HT-based line de...

A storage area network (SAN) is a high-speed special-purpose network (or subnetwork) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users. In SAN, computers service local file requests directly from shared storage devices. Direct device access eliminates the server machines as bottlenecks to performance and availability. Communication is unnecessary between computers, since each machine views the storage as being locally attached. SAN provides us to very large physical storage up to 64-bit address space, but traditional file systems can't adapt to the file system for SAN because they have the limitation of scalability. In this paper we propose a new mechanism for file system using dynamic bitmap assignment. While traditional file systems rely on a fixed bitmap structures for metadata such as super block, inode, and directory entries, the proposed file system allocates bitmap and allocation area depend on file system features. Our approaches give a solution of the problem that the utilization of the file system depends on the file size in the traditional file systems. We show that the dynamic bitmap mechanism this improves the efficiency of disk usage in file system when compared to the conventional file systems.

This paper discusses the development of softwareengineering class projects that have produced tools which have been used to enrich the educational experience of engineering students, the end users of the software. The projects have involved the creation, maintenance and evolution of software that helps the students determine their major, understand their learning style, develop a semester-by-semester plan of study, and formulate a class schedule each semester. The evolution of the structure of the softwareengineering project process is first presented. Having "internal" clients (i.e. those who are employees of the university) for projects that directly benefit engineering students is then compared to having "external" clients. The benefits gained by all stakeholders through these projects and data supporting the satisfaction levels of those stakeholders is presented. Finally, there is a discussion of funded research projects that have been spun off from of these projects, and the plans for the further educational software development through these grants.

A new nanorobotics platform under development and which could be used for high-throughput biomedical applications at the nanometer-scale is briefly described. Each platform is based on a fleet of approximately 100 miniature autonomous instrumented robots, each capable of nanometer-scale operations. A central computer coordinates the operations of each miniature robot based on instructions received previously.
Currently, a large gap exists between the number of open softwareengineering positions and the number of qualified software engineers to fill those positions. The Industry/University (I/U) subgroup of the Working Gro...

A software control system for an autonomous mobile robot must be capable of performing many complex processing tasks in real time. Such tasks may include localising within the environment, recognising objects or safely avoiding static and dynamic obstacles. The focus for our team this year was to build a solid structural base, to be used in future RoboCup competitions. This led us to concentrate on development of effective reusable components such as a robust vision system. The RoboMutts team was a joint venture between the University of Melbourne and RMIT University. This paper focuses on the parts of the system developed at the University of Melbourne.
The paper presents a novel approach to the analysis of typed logic programs. We assume regular type descriptions of logic program variables provided by regular tree grammars. Types are used to identify components of t...
