Buildings are designed and built to sustain its initial functions and beauty for both the present and future users. Building required maintenance for high performance regardless of whether it meets the sustainability consideration or not. An important segment in the maintenance management system is the identification and analysis of defects in the buildings and the urgency of repair needed. Def...

An important activity in urban three-dimensional (3D) mobile navigation is browsing the buildings in the environment and matching them to those in the 3D city map. There are different factors affecting the recognition process such as changes in the appearances of buildings, weather, and illumination conditions. The current aim was to study the salience of different types of visual cues in the r...

The effect of a commercial manure additive (Alliance®) on ammonia (NH3) emissions was evaluated in commercial 1000-head grow-finish swine buildings over a six-month period. The test was conducted in two treated and two control buildings at a modern swine-finishing site consisting of nine identical buildings. Automatic spray application systems in the treated buildings intermittently sprayed the...

This paper describes a method to automatically construct a 3D geometric model of an urban area by merging features extracted from a cadastral map of the area and from the corresponding digital elevation model (Dem). The cadastral map and the Dem are both transformed into two sets of contour segments: The segments extracted from the map represent contours of buildings and blocks of buildings, wh...

Sustainable tall buildings that provide comfortable, healthy and efficient indoor environments are clearly desirable as the densification of living and working space for the world’s increasing population proceeds. For environmental concerns, these buildings must also be energy efficient. One component of these tasks is the provision of indoor air quality and thermal comfort, which can be enhanc...

This paper presents a novel device called Sense Diary for intelligent buildings. To introduce the new device and its applied system, a brief review of sensor-based systems applied in buildings has been conducted, which is based on current literature and products. The aim of this review is to understand current research and development situation of sensor-based systems that have been developed f...

This thesis discusses the feasibility of structural magnetic induction dampers for dampening mechanical vibrations in buildings subjected to strong dynamic excitations. The concept of energy harvesting in various fields of engineering is first examined. Then it is applied to the design of magnetic induction dampers in buildings. Various implementations of these dampers are proposed and the rela...

They are many researches on computer graphics to generate a virtual city. The principal method is to start with an urban pattern and then to generate buildings, but how to create a city with buildings that was already designed? We propose a different approach with a system based on creating an urban pattern after loading buildings, which are loaded randomly, then follow a vector until its end. ...
