Participants made paired comparisons of square sizes, with blue squares presented on the left side of a computer screen and red squares on the right. Context was manipulated by varying the distributions of blue and red squares separately. In Experiment 1, target squares from low-range distributions were judged larger than the same-size squares from high-range distributions. In Experiment 2, ran...

Related Concepts – Access control – Access control policy – Security kernel Definition A reference monitor concept defines a set of design requirements on a reference validation mechanism, which enforces an access control policy over subjects' (e.g., processes and users) ability to perform operations (e.g., read and write) on objects (e.g., files and sockets) on a system. – The reference valida...

The checking of monitor unit calculations is recognized as a vital component of quality assurance in radiotherapy. Using straightforward but detailed computer-based verification calculations it is possible to achieve a precision of 1% when compared with a three-dimensional (3D) treatment planning system monitor unit calculation. The method is sufficiently sensitive to identify significant error...

This chapter focuses on digital technologies and geometry education, a combination of topics that provides a suitable avenue for analysing closely the issues and challenges involved in designing and utilizing digital technologies for learning mathematics. In revealing these issues and challenges, the chapter examines the design of digital technologies and related forms of learning activities fo...

Corpus based studies of spontaneous speech showed that filled pauses tended to precede relatively long and complex constituents. We examined whether listeners made use of such a tendency in speech processing. We tested the hypothesis that when listeners heard filled pauses they tended to expect a relatively long and complex phrase to follow. In the experiment participants listened to sentences ...

We describe past and ongoing research in our two groups by briefly highlighting a few particularly relevant projects. Our research involves conducting evaluations of multiple monitor systems, developing new interaction techniques for distributed display environments, and inventing new applications for environments rich in computer displays.

City lighting represents an important part of the maintenance and energy budget for many towns. For these reasons, it is important to monitor and manage the energy consumption in order to reduce the consumption with a low impact to the users. The proposed system allows monitoring and managing the lighting to reduce consumption and the cost of the maintenance and management. The system was teste...

BACKGROUND Dementia care providers need a clinical assessment tool similar to the blood pressure cuff (sphygmomanometer) used by clinicians and patients for managing hypertension. A "blood pressure cuff " for dementia would be an inexpensive, simple, user-friendly, easily standardized, sensitive to change, and widely available multidomain instrument for providers and informal caregivers to meas...
