Current efforts move to improve healthcare services in Saudi Arabia (SA). Given the essential roles of these services within the country, ongoing effort to improve health informatics services in SA is required in order to ensure the sector is up-to-date. One area for improvement focuses on the referral system in place in Madinah city. This paper presents a solution to the above problem by proposing a Web-based healthcare information system link that can connect four healthcare centres in Madinah city. This will serve as a pilot project. This link could help healthcare providers to access patient information within their own system. Many healthcare applications have problems with interoperability. Hence, one of the aims of this research is to look at system integration of some of the existing healthcare information systems.

The NSF Digital Clay project is focused on the design, prototyping, integration, and validation of a computer-controlled physical device capable of taking any of a wide range of possible shapes in response to changes in a digital 3D model or to changes in the pressure exercised upon it by human hands. Although it clearly is a natural and unavoidable evolution of 3D graphical user interfaces, its unprecedented capabilities constitute a major leap in technologies and paradigms for 3D display, for 3D input, and for collaborative 3D design. In this paper, we provide an overview of the Digital Clay project and discuss the challenges, design choices, and initial solutions for a new finger sculpting interface designed for the Digital Clay and prototyped using conventional 3D I/O hardware.

A new systolic algorithm which computes image differences in run-length encoded (RLE) format is described. The binary image difference operation is commonly used in many image processing applications including automated inspection systems, character recognition, fingerprint analysis, and motion detection. The efficiency of these operations can be improved significantly with the availability of a fast systolic system that computes the image difference as described in this paper. It is shown that for images with a high similarity measure, the time complexity of the systolic algorithm is small and, in some cases, constant with respect to the image size. A formal proof of correctness for the algorithm is also given.
