background: in order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (ntcp), we consider the fractional dependence of the ntcp on the wall thickness (tw) and rectal displacement (rm). materials and methods: the two-dimensional ntcp model (ntcp2d) was developed using radiotherapy plans of ten randomly selected patients with prostat...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

The Video Window is a video screen hanging next to a window on my bedroom wall, showing the image from a camera mounted to show the skyline from outside that same window. This paper describes the appeal of living with such a system, and the intermingled aesthetic, utilitarian and practical issues involved in its creation and the experience it offers. About six months ago 1 , I mounted a small v...

Several research studies have identified window-wall interfaces as one of the major sources water ingress through building envelopes. Window-wall can either be sealed by means face-sealed or drained sealing systems. In general, it is assumed that show an improved rainwater resistance compared to interfaces. However, only a limited number found in literature evaluating watertightness performance...

The impacts of building envelope designs are significant on indoor thermal environment, especially for naturally ventilated buildings. Parametric façade studies were investigated for various orientations, window sizes and shading devices by using building simulation (ESP-r) and CFD (FLUENT) coupling program to predict indoor thermal environment in an accurate and quick way. Two typical weeks we...

Window-to-Wall Ratio(WWR) is a crucial building envelope element that decides the air conditioning and lighting energy consumption in building. Controlling WWR within reasonable range of great significance to conservation. Due importance WWR’s selection Revit modeling, an automatic compliance check software Modeling developed ensure model range. The given Design Standard for Energy Efficiency P...
