We present an algorithm for automatically constructing a decompositional shape model from examples. Unlike current approaches to structural model acquisition, in which one-to-one correspondences among appearance-based features are used to construct an exemplar-based model, we search for many-tomany correspondences among qualitative shape features (multi-scale ridges and blobs) to construct a ge...

Airborne laser altimetry has become a very popular technique for the acquisition of digital elevation models. The high point density that can be achieved with this technique enables applications of laser data for many other purposes. This paper deals with the construction of 3D models of the urban environment. A three-dimensional version of the well-known Hough transform is used for the extract...

Rising floodwaters in the Blue Nile (BN) and White (WN) tributaries continually affects people’s lives safety of infrastructures Khartoum, capital Sudan. Recently, floods have covered a wide area Khartoum destroyed many buildings bridges. We conducted this study to evaluate predict flood effects around BN WN make recommendations view upcoming disasters. Land-use/land-cover (LULC) changes after ...

Existing buildings can be at a greater seismic risk due to non-conformance current design codes and may require structural retrofitting improve building performance. The most recent example of that seen from the 2015 AD earthquake in Nepal other sub continental regions, where numbers were destroyed with more fatal consequences have drawn attention government authorities general public for resis...

The inelastic response of existing reinforced concrete (RC) buildings without seismic details is investigated, presenting the results from more than 1000 nonlinear analyses. The seismic performance is investigated for two buildings, a typical building form of the 60s and a typical form of the 80s. Both structures are designed according to the old Greek codes. These building forms are typical fo...

Non intrusive load monitoring (NILM), or energy disaggregation, is the process of separating the total electricity consumption of a building as measured at single point into the building’s constituent loads. Previous research in the field has mostly focused on residential buildings, and although the potential benefits of applying this technology to commercial buildings have been recognised sinc...
