We present a key-distribution scheme that is particularly well suited for use in conjunction with a session-less datagram protocol such as IP or IPv6. We describe how this scheme can be used for both IP unicast and multicast applications, providing an approach for scalable multicast key distribution. We also describe an implementation of this scheme on the(More)
Although experts should be well positioned to convey their superior knowledge and skill to novices, the organization of that knowledge, and particularly its level of abstraction, may make it difficult for them to do so. Using an electronic circuit-wiring task, the authors found that experts as compared with beginners used more abstract and advanced(More)
This paper outlines the design of a simulator to allow for the optimisation of clinical workflows within a pathology laboratory and to improve the laboratory's efficiency in the processing, testing, and analysis of specimens. The aim of this research project is to determine whether the simulator can improve clinical workflows since it's design is based on(More)
There are many user interface design and development principles within the field of Human Computer Interaction (HCI). When implementing a project, it can often be difficult to ensure that these design principles are being considered and that a positive user experience is being achieved. This paper outlines the proposition of an interactive HCI audit tool(More)
