the geometry of a collector is one of the important factors that can increase the incident radiation on the collector surface. in the present study, the incident radiation for a stationary collector with cone geometry, i.e. a conical collector, is theoretically and experimentally investigated. this type of collector is always stable and does not need a fixture to install. moreover, it has a sym...

This issue includes fifteen papers selected from the 2010 Conference on Dependable Computing (CDC2010). The papers in this issue mainly focus on the theoretical investigation of Dependable Computing. Thorough theoretical investigation is the cornerstone of successful applications. It is an excitement to have all experts, professionals and scholars share their creative thoughts and inspirations ...

Systems analysis has been practiced by expert systems analysts or IT people in the third person perspective or objective one. We question this style of systems analysis and investigate into what it should be and who should practice it in an unpredictable, turbulent environment. The existing systems analysis methods such as UML help systems analysts ignore the differences of individual workers a...

This paper is part of a work in progress that aims to define a narrative theory adapted for optimal use in the Virtual Reality (VR) medium. In addition to theoretical results and findings on the development of an Emergent Narrative (EN) concept, the authors present their convictions regarding Virtual Storytelling (VS) and narrative consideration. Finally, an Emergent Narrative model is describe...
