Since the early 1980's, intelligent and adaptive systems have appeared and have been written about in a variety of guises. Although there are many differences between such systems as adaptive user interfaces, intelligent help systems and explanation systems, there are many similarities as well. The most notable of these is that they all require user models(More)
Although it is well accepted that bone architecture adapts to withstand the loads placed on it, the manner in which this occurs in the immature growing skeleton is not fully understood. To investigate the possible mechanisms, we have compared morphometric differences between tibiae from chickens with fast and those with slow growth potential and also(More)
Perspective is the definitive guide to empirical research in HCI. The book begins with foundational topics including historical context, the human factor, interaction elements, and the fundamentals of science and research. From there, you'll progress to learning about the methods for conducting an experiment to evaluate a new computer interface or(More)
The high resistance grounding (HRG) of 480-4160-V industrial power systems increases service continuity, enhances personnel safety, and reduces equipment damage when a ground fault occurs. HRG allows maintenance personnel to quickly and safely locate a ground fault while avoiding unscheduled downtime. An abundance of literature has been published on HRG(More)
PURPOSE To evaluate computed tomographic (CT) colonography as a screening tool for average-risk asymptomatic subjects with regard to participation, acceptability, and safety. MATERIALS AND METHODS CT colonography for colorectal neoplasia screening was offered to 2,000 subjects aged 50-54 and 65-69 years. Only asymptomatic subjects at average risk of(More)
We consider the significant work in both the human-computer interaction and artificial intelligence fields in the area of intelligent interfaces, placing into a structure the disparate strands of research work. We treat design and implementation issues, covering the relationship between user interface management systems (UIMS) architectures and interface(More)
Bone strength is, in part, dependent on a mechanical input that regulates the (re)modelling of skeletal elements to an appropriate size and architecture to resist fracture during habitual use. The rate of longitudinal bone growth in juveniles can also affect fracture incidence in adulthood, suggesting an influence of growth rate on later bone quality. We(More)
