Path-Cyclopedia

Wikis in teaching and assessment: the M/Cyclopedia project

In a knowledge-based, networked economy, students leaving university need to have attained skills in collaborative and creative project-based work and to have developed critical, reflective practices. This paper outlines how a wiki can been used as part of social constructivist pedagogical practice which aims to develop advanced ICT literacies in university students. The paper describes the imp...

Being on the right path

Being on the right pathThe 1st issue of the Iranian Journal of Radiation Research (IJRR) was published two years ago (June 2003). This journal was initiated to bring together the various disciplines of radiation oncology, radiation biology, medical physics, nuclear medicine and other related subjects to intensify the dialogue between basic and clinical researchers especially those working in Ir...

Secluded Path via Shortest Path

We provide several new algorithmic results for the secluded path problem, specifically approximation and optimality results for the static algorithm of [3, 5], and an extension (h-Memory) of it based on de Bruijn graphs, when applied to bounded degree graphs and some other special graph classes which can model wireless communication and line-of-sight settings. Our primary result is that h-Memor...

Accelerating Path Tracing by Eye Path Reprojection

Recently, path tracing has gained interest for real-time global illumination since it allows to simulate an unbiased result of the rendering equation. However, path tracing is still too slow for real-time applications and shows noise when displayed at interactive frame rates. The radiance of a pixel is computed by tracing a path, starting from the eye and connecting each point on the path with ...
