This paper compares the paradigms of LiDAR and aerophotogrammetry in the context of building extraction and briefly discusses two roof building contour extraction methodologies. The assets and drawbacks of both data capturing system have been reported several times. In general, empirical and theoretical studies have confirmed that LiDAR methodologies are more suitable in deriving building heigh...

A green roof can reduce the peak thermal cooling loads and reduce the building energy consumption during the summer. It is also necessary to understand the thermal performance of these green roof assemblies during the winter when affected by an accumulation of snow on the rooftops. This study presents an experimental investigation and discusses the snow influence on the heat transfer processes ...

The organizing centers and molecules that pattern the cerebral cortex have been elusive. Here we show that cortical patterning involves regulation of the Lhx2 homeobox gene by the roof plate. Roof plate ablation results in reduced cortical size and Lhx2 expression defects that implicate roof plate signals in the bimodal regulation of Lhx2 in vivo. Bimodal Lhx2 regulation can be recapitulated in...

3D city model reconstruction is one of the main application of airborne laser scanning system. Roof detection is a primary step which needs to find each roof from irregular point clouds with noise points involved. Another problem existed in roof detection is that the detected sequence of roofs will affect the size and shape of detected roofs even though a lot fancy algorithm are applied. In thi...

Urbanism directly affects the hydrological cycle. One of the ways to manage runoffs in urban areas that is considered nowadays is green roof creation. Green roof is mainly created in humid and semi-humid areas, and efficiency of green roofs in arid and semi-arid areas has attracted less attention. In the current study, to evaluate the effect of green roof in arid and semi-arid to reduce runoff,...

10 The refractile (R) bodies found in Caedibacter taeniospiralis, a bacterial endosymbiont of Paramecium 11 tetraurelia, are large, polymeric protein structures that can switch between two conformations. At 12 cytoplasmic pH, they resemble coiled ribbons of protein 500nm in diameter. At low pH, they extend to 13 form hollow needles up to 20 microns long. They can be expressed heterologously fro...

This paper is about distributed scheduling where individual agents have potentially conflicting interests. It is motivated by BT’s workforce scheduling problem, where multiple service providers have to serve multiple service buyers. The service providers and buyers all attempt to maximize their own utility. The overall problem is a multi-objective optimization problem; for example, one has to m...

As a solution to maintain, process and enrich knowledge in the multimedia description framework we are constructing, we propose a forward chaining knowledge base and reasoning engine, supporting RDF documents and OWL Lite ontologies, with the ability to perform non-monotonic, retractable inference. Within our framework, the knowledge over the media collection can be collected in several ways. A...
