An analytic technique for router comparison
Design automation of electronic systems is generally separated into a number of distinct areas of effort. Breuer [1] has divided design automation into the areas of logic synthesis, gate simulation, partitioning, placement, routing, and fault detection and diagnosis. While this separation may not be complete or entirely accurate, these functions generally must be performed.

An experimental comparison of force directed placement techniques
Force-directed placement algorithms are experimentally compared using several sample problems. Significant differences are noted in the computational efficiency of the algorithms, and in the relationship of the placement solution to the routability of the resulting board.

Combining CBR with Interactive Knowledge Acquisition, Manipulation and Reuse
Because of the complexity of aerospace design, intelligent systems to support and amplify the abilities of aerospace designers have the potential for profound impact on the speed and reliability of design generation. This article describes a framework for supporting the interactive capture of design cases and their application to new problems, illustrating the approach with a discussion of its use in a support system for aircraft design. The project integrates case-based reasoning with interactive tools for capturing expert design knowledge through "concept mapping." Concept mapping tools provide crucial functions for interactively generating and examining design cases and navigating their hierarchical structure, while CBR techniques provide capabilities to facilitate retrieval and to aid interactive adaptation of designs. The project aims simultaneously to develop a useful design aid and more generally to develop practical interactive approaches to fundamental issues of case acquisition and representation, context-sensitive retrieval, and case adaptation.

Case-Based Decision Support for Intelligent Patient Knowledge Management
The majority of healthcare workers in hospitals continue to record, access and update important patient information using paper charts. Disparate patient data (clinical information, laboratory results and medical imagery) is entered by different caregivers and stored at different locations around the hospital. This is a cumbersome, time consuming process that can result in critical medical errors such as documents being mislaid or prescriptions being misinterpreted due to illegible handwriting. Hospitals everywhere are moving to integrate health data sources using electronic health record (EHR) systems as well as taking advantage of the flexibility and speed of wireless computing to improve the quality and reduce the cost of healthcare. We are developing a mobile application that allows doctors to efficiently access accurate real-time patient information at the point-of-care. The system can assist caregivers in automatically searching through very large repositories of previous patient cases as increasingly large hospital databases are making manual searches of such information unfeasible. The system performs computational prognosis by providing decision support for pre-screening of medical diagnosis. A presenting patient's symptoms can be input to a portable device and the application can quickly retrieve the most similar profiles with known diagnoses from large databases which can be used to compare treatments, diagnosis, test results and other information

Task-Based Image Annotation and Retrieval
In order to address problems of information overload in digital imagery task domains we have developed an interactive approach to the capture and reuse of image context information. Our framework models different aspects of the relationship between images and domain tasks they support by monitoring the interactive manipulation and annotation of task-relevant imagery. The approach allows us to gauge a measure of a user's intentions as they complete goal-directed image tasks. As users analyze retrieved imagery their interactions are captured and an expert task context is dynamically constructed. This human expertise, proficiency, and knowledge can then be leveraged to support other users in carrying out similar domain tasks. We have applied our techniques to two multimedia retrieval applications for two different image domains, namely the geo-spatial and medical imagery domains.

Multimodal Interaction - Improving Usability and Efficiency in a Mobile GIS Context
The context of mobility raises many issues for GIS applications. Mobile device limitations, including pen input whilst in motion, result in interfaces which are difficult to navigate and interact with. However, comparatively little research has been conducted to address the interface mobility problem for GIS. We are particularly concerned with the limited interaction techniques available to users of mobile GIS which play a primary role in contributing to the complexity of using such an application whilst mobile. Our research focuses on multimodal interfaces as a means to present users with a wider choice of modalities for interacting with GIS applications. The focus of this paper concerns a comprehensive user study which demonstrates the benefits, in terms of usability and efficiency, of a multimodal interface for the CoMPASS mobile GIS which we have developed.
