This paper will focus on the extraction of 3D urban building from ALS (Airborne Laser Scanner) data in built-up areas with the incorporation of GIS data . Sample terrain points are firstly captured by the integration of normalized DMS data and GIS road network data. Rough DEM is interpolated from the sample terrain points, which make it possible to extract potential building by subtracting from...

Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

Automated building extraction from multi-source data has attracted great attention in recent years. This paper presents an approach to automated building extraction by fusion of image data, height data and 2D ground plans. In this approach buildings are detected using ground plans and height data. A split-and-merge process is applied to fuse image and height data and derive the parametric forms...

Many major cities in the U.S. and throughout the world, including New York City, have areas where clusters of skyscrapers are present. Why do builders choose to build real estate with such height? And, how does the choice of height depend on characteristics of nearby buildings, demographics, and other spatial factors? Using a data set consisting of detailed information for 458 skyscrapers in Ne...

the concentration of pollutants around tall buildings can be influenced by many factors such as down wind effects, waves, airflow due to free convection of heat transfer, building height etc. the main objective of this research was the investigation of the variation of pollutants concentration at different heights around tall buildings. research was carried out measuring parameters such as co o...

The design and implementation of personal communications systems requires the prediction of wave propagation relating to signal-to-noise and signal-to-interference calculation in a cellular system [93]. Small-cell network configurations especially microand pico-cell types are of major interest for urban environments. The commonly used criteria for the definition of a micro-cell is related to th...

The condition of the space environment as a result interaction physical, chemical, and biological factors, in complex way, can have acute chronic effects on physical psychological health occupants. This was incidence sick building syndrome, efforts to reduce eliminate syndrome were presented this case study. aim produce healthy indoor quality sustainable use by its methods used minimum Indonesi...
