Geospatial distribution of population at a scale of individual buildings is needed for analysis of people’s interactionwith their local socio-economic and physical environments. High resolution aerial images are capable of capturing urban complexities and considered as a potential source formapping urban features at this fine scale. This paper studies population mapping for individual buildings...

Recall that the quasi-isometry group QI(X) of a metric space X is the set of equivalence classes of quasi-isometries f : X → X, where two quasiisometries f1, f2 are equivalent iff supx d(f1(x), f2(x)) <∞ (here we consider G as a metric space with a word metric). One approach to this question, which has been the most successful one, is to find an ‘optimal’ space X quasi-isometric to G and show t...

Reducing energy use in buildings is a critical component of meeting carbon reduction commitments. There are several ways of accomplishing this goal, each of which emphasizes actions by a different set of stakeholders. Much of the work in this area follows a physical, technical and economic model of the built environment (Lutzenhiser, 1993). In this scenario, architects, engineers and efficiency...

In order to realize more precise geometrical models of existing buildings, range images are used to represent the geometrical information of the façades of existing buildings. First, the range images of existing buildings are acquired using laser scanners mounted on a data acquisition vehicle which runs along the street. After removing obstacles, edge detection based segmentation and histogram ...

In Australia, many large cities suffered the loss of important buildings during the building boom of the 1960s. During this time of demolition and re-building the ‘face’ of major cities changed forever. This period of savage removal of heritage and significant buildings has been the subject of much interest and debate till this day. There exists the need to provide virtual models of Australian ...

Recently, Cartwright and Woess [5] provided a detailed analysis of isotropic random walks on the vertices of thick affine buildings of type Ãn. Their results generalise results of Sawyer [18] where homogeneous trees are studied (these are Ã1 buildings), and Lindlbauer and Voit [9], where Ã2 buildings are studied. In this paper we apply techniques of spherical harmonic analysis to prove a local ...

Three different Swedish lightweight multistory buildings have been investigated with respect to the flanking transmission over an inner wall. Among the buildings analysed, one of them had been used by residents for three years and the two other were only just erected and being built respectively. A tapping machine and a Japanese ball were used as excitation sources so as to produce vibrations i...

The applicability of the utilisation factor method EN ISO 13790 is studied in modern Finnish buildings in the cold climate of Finland. The heatdemand results of EN ISO 13790 are compared against a validated dynamic simulation tool. It is shown that, with the default values of the numerical parameters of the utilisation factor, EN ISO 13790 gives in Finnish conditions as much as 46% higher or 59...

An integrated damage detection system, which was developed to detect the collapsed buildings due to Kocaeli earthquake, occurred on 17 August 1999, is introduced. The implementation of the system was carried out in a selected area of the city of Golcuk, TURKEY. The developed system is composed of three components: (i) input, (ii) analysis and (iii) output. In the input component, the post-event...
