This study is a preliminary operation of a global project which goal is to interpret urban scenes from satellite images in order to recognize and classify roads and buildings. Actually, the research is focused on buildings. We plan to apply these algorithms on the forthcoming satellite data of PLEIADE HR which will follow SPOT5. The input data consists of a panchromatic stereopair of satellite ...

The growing demand for detailed city models has stimulated research on efficient 3D data acquisition. Over the past years, it has become evident that the automatic reconstruction of urban scenes is most promising if different types of data, possibly originating from different data sources are combined. In the approach presented in this paper the geometric reconstruction of urban areas is based ...

Environmental pollution problems have been globally main concern in all fields including economy, society and culture into the 21 century. Beginning with the Kyoto Protocol, the reduction on the emissions of greenhouse gas such as CO2 and SOX has been a principal challenge of our day. As most buildings unlike durable goods in other industries have a characteristic and long life cycle, they cons...

French companies are legally required to develop action plans to improve employment and work conditions for older workers ("plans seniors"). These plans contain measures oriented towards recruiting, career evolution, skills developme1nt, knowledge transmission and improvement of work conditions. A tool for assessing work situations experienced by council buildings caretakers ("gardiens") was us...

In this paper, the build and survived railway stations over the time at which first railway lineconstruction started at Turkey until the present had been examined and the ones which were out of use and lost theiroriginal function with time had been determined. Also the determined building stock had been evaluated based onthe principle of giving new function to the old buildings, in especial of ...

To efficiently plan future personal communications services, we need to solve various mobility/traffic problems in onedimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) microor pico-cell environments. Although many users exhibit vertical motion inside elevators in high-rise buildings, there have been no studies regarding cell planning which take into account vertical motion w...

Man has used the stack ventilation strategy for centuries to ensure comfortable indoor environment in their buildings. Today, in the conditions of the denser built environment and the need for deep-plan buildings seems inevitable, the application of stack ventilation strategy has become more important, especially when the natural cross ventilation has limited functions. However, realizing the f...

Experts in construction engineering are overwhelmed by regulatory texts. It is a heavy task to go through these texts and get an unambiguous list of requirements they contain. Moreover, with regard to the number of texts and the diversity of their writers, we cannot neglect the possibility of getting inconsistencies. Finally, these requirements are to be put close to digital representation of b...

In response to an estimation of the likelihood of occurrence of the Tonankai and Nankai earthquakes, it is predicted that tsunami damage will occur in the JR Osaka Station area, the third biggest business center in Japan. The purpose of this study is to propose a system that evaluates the effectiveness of tsunami evacuation guidance and tsunami countermeasures, based on computer simulation of b...
