Abstract. An important shortcoming of client-side cryptography on consumer devices is the poor protection of secret keys. Encrypting the keys under a human-memorizable password hardly offers any protection when the device is stolen. Trusted hardware tokens such as smart cards can provide strong

Abstract—Information technology plays a very important role in society. People with disabilities are often limited by slow text input speed despite the use of assistive devices. This study aimed to evaluate the effect of a dynamic on-screen keyboard (Custom Virtual Keyboard) and a word-prediction

for research and education in molecular biology, and for enhancing the scientific environment for collaboration and exploration. We have adapted an augmented reality system to allows virtual 3-D representations (generated by the Python Molecular Viewer) to be overlaid onto a tangible molecular model. Users can

though they had to move progressively faster. The main result was that at the end of learning the hand paths that subjects adopted for each object were predicted by OFC using a simple cost function. Thus the assumption was that the lead-in training comprised adaptation -subjects first learn the complex

and adopt the techno-pedagogy or the virtual class room that is a wonderful treasury of knowledge. The virtual class room is not a teacher centered, it is learner centered where the choice of courseware, methodology, pace, place and time is as learners' wish.

Abstract This paper discusses the role of models in the development of an interactive artwork made as the result of interdisciplinary collaboration. A variety of different types of model were used, each with different functions and status to the team. Keywords: architecture, cellular automata
