We assessed the total energy required to manufacture, install and maintain an extensive, sedumplanted green roof over its assumed life of 20 years in the Mid-Atlantic region of the U.S. using the method of emergy analysis. We estimated its environmental benefits as the sum of summer electricity savings due to cooler building temperatures, primary production of biomass and reduction in intensity...

Nineteen patients with roof impingement of an anterior cruciate ligament graft had their grafts inspected during second-look arthroscopy. The diagnosis of roof impingement was suspected from the clinical findings of an effusion, extension deficit, recurrent instability, or anterior knee pain. The diagnosis was confirmed when a portion of the tibial tunnel was anterior to the tibial intersection...

The roof dual bound for quadratic unconstrained binary optimization is the basis for several methods for efficiently computing the solution to many hard combinatorial problems. It works by constructing the tightest possible lower-bounding submodular function, and instead of minimizing the original objective function, the relaxation is minimized. However, for higher-order problems the technique ...

energy conservation in buildings plays a vital role for sustainable development of societies and nations. although, newer buildings in developing nations are being constructed using energy conservation approach, existing buildings have higher energy demand to meet the desired comfort. excessive energy demand for cooling the built environment is a major problem over most of the arid climatic zon...

In this paper, we present a Self-Avoiding Polygon (SAP) model for describing and detecting complex gable rooftops from nadir-view aerial imagery. We demonstrate that a broad range of gable rooftop shapes can be summarized as self-avoiding polygons, whose vertices correspond to roof corners. The SAP model, defined over the joint space of all possible SAPs and images, combines the shape prior emb...

Purpose To report a case of lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to the orbital roof. Observations A 23-year-old female was presented with right lagophthalmos. Five months prior to consult at our clinic, she suffered from a penetrating trauma to the frontal lobe of the brain through the right orbital roof with cerebrospinal fluid leakage. Decompressive cranie...

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...

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...
