High-resolution satellite imagery provides an important new data source for building extraction. We demonstrate an integrated strategy for identifying buildings in 1-meter resolution satellite imagery of urban areas. Buildings are extracted using structural, contextual, and spectral information. First, a series of geodesic opening and closing operations are used to build a differential morpholo...

It is well known that mobility plays an important role in the performance of MANET protocols. Investigations of the impact of physical layer indicates that the physical layer also plays an important role. This paper presents tools for modeling the environment for MANETs. This environment is defined in terms of buildings, offices, hallways, sidewalks, and roads. Within this environment, the move...

This paper aims to investigate the energy saving and carbon reduction performance of cross-laminated timber residential buildings in the severe cold region of China through a computational simulation approach. The authors selected Harbin as the simulation environment, designed reference residential buildings with different storeys which were constructed using reinforced concrete (RC) and cross-...

AIM To assess the risk factors for deaths and injuries caused by earthquakes in a high-risk earthquake zone. METHODS A cross-sectional study was carried out in Eber town, Cay County, following the earthquake of February 3, 2002 in Afyon, Turkey. This area was particularly affected by the earthquake, with high number of casualties, including many fatalities. The study included 812 persons livi...

Near-field pollutant dispersion in the urban environment involves the interaction of a plume and the flow field perturbed by building obstacles. In the past two decades, micro-scale Computational Fluid Dynamics (CFD) simulation of pollutant dispersion around buildings and in urban areas has been widely used, sometimes in lieu of wind tunnel testing. This paper reviews current modeling technique...

When catastrophic earthquakes happen and affect cities and settlements, immediate and efficient actions are required which ensure the minimization of the damage and loss of human lives. Responding local and national authorities should be provided in advance with information and maps where the highest damages due to unfavourable, local site conditions and earthquake related secondary effects suc...

This study supplemented the National Air Emissions Monitoring Study (NAEMS) by making comprehensive measurements, over a full calendar year, of odor emissions from five swine and four dairy rooms/buildings (subset of the total number of buildings monitored for the NAEMS project). The measurements made in this project included both standard human sensory measurements using dynamic forced-choice ...

We investigate the existence of the principal-agent (PA) problem in non-government, non-mall commercial buildings in the U.S. in 2003. The analysis concentrates on space heating and cooling energy consumed by centrally installed equipment in order to verify whether a market failure caused by the PA problem might have prevented the installation of energy-efficient devices in nonowner-occupied bu...
