Green roof system is considered a relatively new concept in Malaysia even though it has been implemented widely in the developed countries. Generally, green roofs provide many benefits such as enhancing aesthetical quality of the built environment, reduce urban heat island effect, reduce energy consumption, improve stormwater attenuation, and reduce noise pollution. A better understanding on th...

Recent approaches for the automatic reconstruction of 3D building models from airborne point cloud data integrate prior knowledge of roof shapes with the intention to improve the regularization of the resulting models without lessening the flexibility to generate all real-world occurring roof shapes. In this paper, we present a method to integrate building knowledge into the data-driven approac...

An easy usable system for the semi automatic acquisition of detailed D building descriptions from a multitude of images is provided This approach tackles robustly and e ciently most of the problems of D building reconstruction namely occlusions inverse mapping and noise The D modeling is based on Con structive Solid Geometry CSG and various automated and supporting tools Our experiences on the ...

Bilaterally symmetric organisms need to exchange information between the two sides of their bodies in order to integrate sensory inputs and coordinate motor control. This exchange occurs through commissures formed by neurons that project axons across the midline to the contralateral side of the central nervous system. The posterior commissure is the first transversal axonal tract of the embryon...

Silica aerogel possesses an ultra-low thermal conductivity by virtue of its nano-structure. Owing to the fragility monolithic aerogel, development and production aerogel-based insulation materials involve incorporation granular with other form composite materials. In present study, application silica-aerogel-incorporated cement paste as render on roof-top surface is coupled installation a novel...

A monitoring system that uses applied geomatics techniques, including terrestrial laser scanning and videogrammetry, has been developed in order to determine the behaviour of as-built membrane roof structures. To accommodate the constraints involved in measuring such structures, for example uniform surface texture and unreachable height, the system adopts a non-contact targeting methodology to ...

In 1948 roof falls were the number one killer of coal miners in America. While the Bureau of Mines had been formed in 1910 to improve coalmine safety, it had largely focused on explosions, for which technological solutions appeared to exist. Roof falls, by contrast, were not amenable to a technical fix. Beginning in 1948, however, the Bureau discovered roof bolting, which it promoted as a safer...

Liquid that resides in a soft elastomer embedded between wearable electronics and biological tissue provides a strain-isolation effect, which enhances the wearability of the electronics. One potential drawback of this design is vulnerability to structural instability, e.g., roof collapse may lead to partial closure of the liquid-filled cavities. This issue is addressed here by overfilling liqui...
