We present an interface for users to conveniently and quickly create a settlement with various standard structures in traditional Chinese architecture. The main page of the interface is a top-down map view of the canvas which allows users to place different structures, such as pavilions, pagodas, halls, houses, gates, moon-gates and bridges onto the scene. Then, the user can custom-design each ...

Having as a starting point the idea of creating a structure with an iconic design, the current article presents all the technical solutions and steps followed in the process of creating this special structure. The structure, having the destination of a showroom for an auto dealer, is presented with an unconventional design of the roof: a roof structure having a double curvature. Starting from a...

For many centuries, the settlements had a fairly uniform image, which was result of use local materials, technology and economic condition population. With development construction profession improvement material conditions, building materials also began to change, market supply has diversified, led changes in appearance buildings. The roof, known as fifth facade, affects external image settlem...

The key factors in the energy-saving design of a building’s exterior in Taiwan are the thermal performance of the roof and window glazing. This study used the eQUEST software to investigate how different types of roof construction, window glasses and sunshield types affect the energy consumption in residential buildings under common scenarios. The simulation results showed that the use of an ap...

A Semi-Automatic Building Extraction system using two or more digitized overlapping aerial images has been enhanced by increased automation for the measurement of saddle-back-roof buildings, hip-roof buildings and boxes. All newly developed modules have been incorporated in the object oriented design of the system. The new methods consist of a ground-point and roof-top matching tool and a robus...

Constant rise in fuel price in recent times has caused manufacturers of heavy commercial vehicles (HCV) to turn to efficient aerodynamic design of trucks, wagons, tractors as well as trailers. The comparative analysis in this study compares the coefficient of drag of the following four aerodynamic configurations of a tractor-trailer combination: 1. Semi-trailer with no devices. 2. Semi-trailer ...
