Two experiments examine how participants vary in their approach to solving an orientation task. Verbal reports from untrained participants in a pilot study revealed that some participants used a strategy based on mental imagery, while others used verbal descriptions to do the task. The two experiments presented here involved training participants to perform the orientation task using one of the...

Rutting of flexible pavement is considered one of the major pavement distresses noted around the world and in Egypt. Many investigators showed at about 55 to 80% of rutting occurred in the surface layer. Rutting of asphalt surface layer may be due to many causes happened during construction phase and service phase. The main objectives of this research are to evaluate the impact of aggregate gra...

Intermediation in Innovation1 by Heidrun C. Hoppe2 and Emre Ozdenoren3 The paper offers a new theoretical framework to examine the role of intermediaries between creators and potential users of new inventions. Using a model of universityindustry technology transfer, we demonstrate that technology transfer offices can provide an opportunity to economize on a critical component of efficient innov...

The paper o¤ers a new theoretical framework to investigate the organization of technology transfer between universities and industry. We ...nd that technology transfer o¢ces (TTOs) can reduce the uncertainty and adverse selection problems between faculty-inventors and industrial ...rms, and thus play a crucial role in forming the market for university inventions. Our results help explain the si...

We describe an unusual ASR application: recognition of command words from severely dysarthric speakers, who have poor control of their articulators. The goal is to allow these clients to control assistive technology by voice. While this is a small vocabulary, speaker-dependent, isolated-word application, the speech material is more variable than normal, and only a small amount of data is availa...

The approximation and integration problems consist of finding an approximation to a function f or its integral over some fixed domain 6. For the classical version of these problems, we have partial information about the functions f and complete information about the domain 6; for example, 6 might be a cube or ball in R . When this holds, it is generally the case that integration is not harder t...

We define visuospatial working memory (VSWM) as the set of cognitive processes used to visualize the locations of things. VSWM is not permanent visual memory; it is a temporary visual workspace used to solve spatial problems. VSWM is ubiquitous in everyday reasoning (for example, visualizing different ways of arranging furniture in a room), and is thought to be particularly important for certai...

In this paper, we present a new method for egocentric video temporal segmentation based on integrating a statistical mean change detector and agglomerative clustering(AC) within an energy-minimization framework. Given the tendency of most AC methods to oversegment video sequences when clustering their frames, we combine the clustering with a concept drift detection technique (ADWIN) that has ri...

We present a computational model of human performance on the Sustained Attention to Response Task, a computer-based task in which people must withhold responses to infrequent and unpredictable stimuli during a period of rapid and rhythmic responding to frequent stimuli. The model, formulated within the ACT-R cognitive architecture, accounts for human performance in terms of two competing strate...

in fact, health strategists and policymakers contribute to the effectiveness and efficiency of planning, providing and evaluating health care, and the use of various capabilities of itc. the evidence for this claim includes: e-government, e-development, e-commerce, e-assurance and the same issues which are pursued in high levels of govemment’s legislative and executive bodies. e-health is consi...
