The current analysis method of thermal insulation performance building envelope neglects the optimization temperature control parameters, which leads to poor performance, low rate and weak convincing results. Therefore, a finite element for high rise is proposed. Compton backscattering technique introduced analyze influence scattering intensity ratio window width on heat transfer coefficient en...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

by having daylighting in mind through a building design process rather than end of it, achieving a more sustainable space is much easier and feasible. since many people spend an important amount of their lives at their working spaces, accessing enough natural light together with satisfying view are essential for their physiological and psychological health. moreover as a daylighted space has a ...

Metal foam is a novel material recently utilized in baffles as an alternative to solid for reducing flow resistance. However, the metal are accompanied by low heat transfer efficiency. To overcome this issue, new design of copper has been suggested research, called having gradient pore density foam. The either increases or decreases towards wall. So, experimental tests were carried out square c...

This study aims to analyze thermal imagery of the sun's orientation and formation openings in residential houses with a modern tropical design concept Medan. The method used is temperature measurement building identification using digital imaging tool, namely Flir CX-3, which carried out during day, as well measuring WWR (window-to-wall ratio) value building. results image analysis show that No...

Conventional techniques in elastography estimate strain as the gradient of the displacement estimates obtained through crosscorrelation of pre- and postcompression rf A-lines. In these techniques, the displacements are estimated over overlapping windows and the strains are estimated as the gradient of the displacement estimates over adjacent windows. The large amount ofnoise at high window over...
