In steam power plants, any improvement in the cooling towers thermal performance will cause the condenser's temperature to decrease; which in turn enhances the power plant's efficiency. Due to water shortage, many power plants all around the world rely on natural draft dry cooling towers (Heller type). In these cooling towers, condenser's exit hot water is pumped to vertical or horizontal finne...

A survey of respiratory symptoms and housing environments using ATS-DLD questionnaires (published by the Environment Agency of Japan) and measurement of Total IgE in serum according to the PRIST method was carried out from June to July, 1984 among elementary school children (766) in Suginami Ward, Tokyo. The relationship between allergic histories or housing environments (types of heaters, hous...

The green roof technology provides environmental benefits by protecting the base roof membrane of buildings against solar radiation and temperature fluctuations and by helping to reduce building’s energy consumption by direct shading. Although several investigations have been performed to explore the energy performance of vegetated roofs as natural cooling devices, there is a lack of data conce...

This paper presents a novel approach to building roof modeling, including roof plane segmentation and roof model reconstruction, from airborne laser scanning data. Segmentation is performed by minimizing an energy function formulated as multiphase level set. The energy function is minimized when each segment corresponds to one or several roof plans of the same normal vector. With this formulati...

This paper presents a life prediction method based on the parameters of actual operation history data collected by existing converter power unit sensors. Firstly, characteristics junction temperature curves forced air-cooled radiator and are extracted, deep learning neural network architecture is constructed characteristics. Then thermoelectric coupling model thermal resistance calculation theo...
