We introduce a construction turning some Coxeter and Davis realizations of buildings into systolic complexes. Consequently groups acting geometrically on buildings of triangle types distinct from (2, 4, 4), (2, 4, 5), (2, 5, 5), and various rank 4 types are systolic.

The emergence of intelligent buildings is founded on the rapid development of microcomputer and internet technology as well as the advance of information and communication technology. With the help of these technologies, office affairs have shifted from the traditional pattern of labor intense and large volume to the flexible, diverse, efficient, user-friendly, and highly reliable operations. M...

The more technology advances, the more there seems to be a basic human yearning to return to nature. This is reflected in a growing number of designers, architects, and artists who are turning to nature’s example to model uses of new technology. San Francisco architect Charles Lee does just that. Lee is a designer, artist, and researcher with the group Bios Design Collective, a group that works...

The goal of our study was to develop an automatic change detection method based on laser scanner, aerial image and map data to be used in updating of building maps. The method was tested in a study area of 2.2 km near Helsinki. Buildings were first detected by segmenting a digital surface model (DSM) derived from laser scanner data and classifying the segments as buildings, trees and ground sur...

Advanced stack-ventilated buildings have the potential to consume much less energy for space conditioning than typical mechanically ventilated or air-conditioned buildings. This paper describes how environmental design considerations in general, and ventilation considerations in particular, shape the architecture of advanced naturally ventilated (ANV) buildings. The attributes of simple and adv...

Economic growth is increasing the demand for energy. Information and Communication Technologies (ICT) have been identified to play an important role in reducing the energy intensity and increasing the energy efficiency of the European Union (EU) economy. ICT will not only improve energy efficiency and help combat climate change, they will also stimulate the development of a large leading-edge m...

the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...

There is currently high interest in developing automated methods to assist the updating of map databases. This study presents methods for automatic detection of buildings and changes in buildings from airborne laser scanner and digital aerial image data and shows the potential usefulness of the methods with thorough experiments in a 5 km 2 suburban study area. 96% of buildings larger than 60 m ...

Estimation of the dynamic characteristics of buildings is a key issue in seismic design technology. Since 1957, the Building Research Institute (BRI), Japan, has been operating a network to monitor strong motion in buildings. In this study, dynamic characteristics of 25 actual buildings in the BRI network were estimated by using strong motion records. Acceleration records from two sensors respe...

abstract today, due to the rapid growth of population, development of the construction industry is a necessity. all around the world, new subjects such as sustainable development, environmental pollution, conservation of resources, and reduction of co2 emission have become the most important research topics among the scientific societies. in recent years, especially after 1997, new tools were i...
