Automatic interpretation of laser scanner data for building detection and map updating was studied. Digital surface and terrain models (DSM and DTM) and an intensity image were created using a helicopter-borne TopEye system recording with 2–3 pulses per m. The DSM was segmented into homogeneous regions using a region-based segmentation method, and the segments were classified as `building ́, `tr...

Subterranean termite control accounted for 50% of the total business turnover of the Malaysian pest control industry in 2000, of which USS8-10 million were spent. About 70% of termite treatments were done on residential premises, 20% on industrial buildings and 10% on commercial buildings. The most important species are Coptotermes travians, C. curvignathus, C. havilandi C. kalshoveniand C. sep...

On April 6, 2009, an earthquake of 6.3 magnitude struck central Italy with its epicentre near L'Aquila, at 42.3502° N, 13.3762°E. The earthquake damaged 3,000 to 11,000 buildings in the medieval city of L'Aquila. Several buildings totally collapsed, 308 people were killed. The post emergency phase till now is just at its beginning step. Conventional surveying techniques using high precision tot...

One of the most important factors affecting the design of the structures, is the impact of the earthquake loadings on the forces and the design displacements. Nevertheless, the influences of the near structures on the existing buildings, that sometimes can cause great changes in forces and displacements, can never be forgotten. Thus, the induced displacement in the adjacent buildings of a newly...

Extraction of geospatial data from the photogrammetric sensing images becomes more and more important with the advances in the technology. Today Geographic Information Systems are used in a large variety of applications in engineering, city planning and social sciences. Geospatial data like roads, buildings and rivers are the most critical feeds of a GIS database. However, extracting buildings ...

The heat flow-rate transferred through the ground represents an important rate of the heat flow-rate dissipated to the outside by the buildings, mainly by the low ones. The buildings architectural solutions associated to the structural solutions, meant to carry out buildings with a low energy consumption used by the thermal utilities (heating / cooling) emphasize the impact of the building – gr...

Meter reading is an important part of billing system for residential and commercial buildings. This often does not reflect the exact or true electricity consumption of such buildings, resulting in an inefficient bill mainly due to human errors. Thus, it is essential to have n efficient and effective system for this measurement purposes. This project is about the design and construction of a per...

In seismic risk mitigation policies, fragility functions of existing buildings play a fundamental role. In this paper, a procedure to develop analytical fragility curves for Moment Resisting Frame Reinforced Concrete buildings is presented. The design of the selected building typologies was performed according to the codes at the time of construction using force-based methods and the state of t...

Crowd-sourced seismic networks in buildings collect important scientific data, in addition to allowing a diverse audience to visualize the vibrations of buildings. Visualization of a building’s deformation requires spatiotemporal interpolation of motions from seismometers that are located wherever the crowd places them. In many cases, a crowd-sourced building network may actually be just a sing...
