it is accepted that the visual comfort in schools depends on the quality of the whole visual environment. this leads to the concern upon the quality and quantity of lighting. currently in iran, in order to calculate energy transfer for public buildings a coefficient is usually used. this coefficient considers the rate of sunlight energy absorption in these kinds of buildings. to increase the de...

The efficiency of lighting installations is a major challenge concerning Governments, productive sectors and individuals. However, the importance of accurate lighting in some areas, especially those related to Health and Wellbeing is so critical that the constraints of energy efficiency and sustainability are not always a priority. This situation has become more critical with the current boom i...

Thermal density and hot spots limit three-dimensional (3D) implementation of massively-parallel SIMD processors and prohibit stacking DRAM dies above them. This study proposes replacing SIMD by an Associative Processor (AP). AP exhibits close to uniform thermal distribution with reduced hot spots. Additionally, AP may outperform SIMD processor when the data set size is sufficiently large, while...

results the results show the artificial lighting obtained by difference methods of the overall lighting from natural lighting in closed blinds mode equal to 266 lux and night lighting 283.5 lux that they have no significant differences with each other (p = 0.269). as well as the illumination intensity obtained from a standard grid method is 283.5 lux and illumination intensity based on luminair...

The ability to monitor the respiratory rate, one of the vital signs, is extremely important for the medical treatment, healthcare and fitness sectors. In many situations, mobile methods, which allow users to undertake everyday activities, are required. However, current monitoring systems can be obtrusive, requiring users to wear respiration belts or nasal probes. Alternatively, contactless digi...

ii Abstract The use of 3D graphics on workstations and PCs becomes increasingly important for modern graphics applications. Also the use of 3D virtual environments on the Internet, e.g. using the VRML standard, is promising to be a great success. In all of these applications, realistic lighting is an important feature to obtain a realistic, and thus convincing, impression of 3D objects and comp...

For beyond 2-D CMOS logic, various 3-D integration approaches specially transistor based 3-D integrations such as monolithic 3-D [1], Skybridge [2], SN3D [3] holds most promise. However, such 3D architectures within small form factor increase hotspots and demand careful consideration of thermal management at all levels of integration [4] as stacked transistors are detached from the substrate (i...
