Lately, a double skin façade (DSF) has been increasingly popular as an aesthetic and shading device. A façade with a secondary skin is employed in buildings to let natural light flow into the building without glare and heat. The purpose of this study is to examine the performance of secondary skin in buildings and to investigate the level of natural lighting in buildings that meets visual comfo...

Natural language processing is an area of artificial intelligence that defines a set of methods and techniques used to automate the translation process between computers and humans or mediate the human-machine communication. NLP focuses on developing systems that allow computers to communicate with people using everyday language and also concerns how computational methods can aid the understand...

We propose and demonstrate an electro-optic spatial light modulator using a deep-proton-exchanged waveguide in periodically poled MgO:s-LiTaO3 thin crystal for UV laser light. The fine pixel profile, the good contrast and low driving voltage were accomplished at 355nm wavelength. Keywords-component; proton-exchage; domain inversion; lithium tantalate; spatial light modulator; ultraviolet (UV) l...

In this paper, extract of papaya leaves are used as a natural dye and combined by variations of solvent concentration applied on DSSC (Dye-Sensitized Solar Cell). Indonesian geographic located on the equator line occasions the magnitude of the potential to develop organic solar cells made from extracts of chlorophyll as a substitute for inorganic materials or synthetic dye on DSSC material. Dye...

The use of a design tool materializing the performative design concept is presented. The association of parametric design with lighting intentions leads to a light-based parametric design approach. This approach have been implemented through an inverse natural lighting model which is intended to aid the daylight design (windows, shading devices or others) in the early stages of architectural de...

Chlorpyrifos is an organophosphate insecticide, used to control foliage and soil-borne insect pests on a variety of food and feed crops. In the natural environment, Chlorpyrifos can be degraded  through  several  possible  processes,  including  photodegradation, biodegradation,  and hydrolysis.  In  the  present  work  the  photodegradation  and  environmental  fate  of  Chlorpyrifos  in aqueo...

iran is one of the limited numbers of ancient countries which is almost totally located on earthquake belt. earthquakes have always been the most important natural hazard in iran. many villages, cities, civilizations and monuments have been partly or totally destroyed by past earthquakes in iran. as a developing country, iran is expanding its cities, industries, dams, power plants etc. the rece...
