Introduction: The pattern of sleep plays an important role in protecting the adolescents’ health. The main objective of this research is to determine the relationship between sufficient sleep (≥ 8 hours of sleep per night on school days) and health-risk behaviours in Portuguese adolescents. Methods: 5,050 participants with an average age of 13.98 (DP ± 1.85), 52.3% of which were female. The ins...

Intermountain Healthcare is a high-performing health system and a recognized leader in quality improvement. We use a clinical integration strategy focused on eight clinical programs to support the practice of evidence-based care. Accelerated improvements that enhance patient safety, clinical excellence, and operational efficiency are tested and then spread across the system via care process mod...

This thesis will cover how some computationally heavy algorithms used in digital image processing and computer vision are implemented with WebGL and computed on the graphics processing unit by utilizing GLSL-shaders. This thesis is based on an already implemented motion detection plug-in used in web based games. This plug-in is enhanced with new features and some already implemented algorithms ...

Computer keyboards are often used to transmit confidential data such as passwords. Since they contain electronic components, keyboards eventually emit electromagnetic waves. These emanations could reveal sensitive information such as keystrokes. The technique generally used to detect compromising emanations is based on a wide-band receiver, tuned on a specific frequency. However, this method ma...

We present a framework for modeling adversaries in security protocol analysis, ranging from a Dolev-Yao style adversary to more powerful adversaries who can reveal different parts of principals’ states during protocol execution. Our adversary models unify and generalize many existing security notions from both the computational and symbolic settings. We extend an existing symbolic protocol-veri...

Light-activated therapies can be used to eradicate diseased cells and tissues in a non-invasive manner. Much attention has been focused on the emerging potential of photothermolysis (also referred to as optical hyperthermia), which involves the conversion of absorbed light into heat via nonradiative mechanisms. Photoactivated effects can be localized and intensified by employing exogenous agent...

The necessary adaptation of mapping applications generates new constraints which should be considered in addition to the traditional cartographic rules used to design maps. Particularly, colors used in the legend could be optimized regarding those constraints. A big stake of such optimization is to preserve the semiotic quality of maps. Therefore, we propose a quantification of the cartographic...

A principal observation in the study of language acquisition is that people exposed to a language as children are more likely to achieve fluency in that language than those first exposed to it as adults, giving rise to the popular notion of a critical period for language learning (Lenneberg, 1967; Long, 1990). This is perhaps surprising since children have been found to be inferior to adults in...

The melting of glacial ice that formed in the middle of the twentieth century may be a source of a cocktail of persistent, bio accumulative toxic substances that can threaten human health and the environment, according to a study by Christian Bogdal, a postdoctoral research fellow at the Swiss Federal Institute of Technology, Zürich, and colleagues in the 1 November 2009 issue of Environmental ...
