The aim of this work is to obtain a reliable testing methodology for the characterization perceived aerodynamic comfort motorcycle helmets. Attention was paid rider’s perception annoying vibrations induced by wind. In optic, an experimental comparative campaign performed in wind tunnel, 16 helmets two different configurations neck stiffness. dataset collected within convolutional neural network...

Modular building is becoming a common sight due to government policies promoting greater automation and productivity. When moving towards modularity, indoor comfort within volumetric modules, such as levels of humidity temperature, natural ventilation, air pollutant transport, have major effect on human health well-being. Computational fluid dynamics simulations (CFD) are used evaluate the effi...

physiologically thermal comfort condition is a limit of temperature and humidity. ,in which thermal control mechanism of human body is in its least activity . thermal comfort conditions not only have impact on sizes of heating and cooling equipment ,but also affects the thickness of insulation, and .energy, consumption of buildings. it is necessary to define thermal comfort condition for differ...

the remarkable development of sciences and technologies in the world of]o today has apparently brought mankind comfort and well-being, but it has also created new problems for humans including environmental pollution, widespread changes in world weather conditions, etc. fossil fuels cause numerous environmental pollutions. in other words, on the one hand poisonous gases enter the environment fo...

As an inseparable organ, courtyards have influenced the history of architecture with their presence in the context of constructed sites and in a wider sense (architecture), it has provided permissive answers to numerous aspects of climatic, cultural and security demands of the residents. Discovering different aspects of environmental and climatic function in the central courtyard of the traditi...

The race towards new heights and architecture has not been without challenges. Tall structures have continued to climb higher and higher facing strange loading effects and very high loading values due to dominating lateral loads. The design criteria for tall buildings are strength, serviceability, stability and human comfort. But the factors govern the design of tall and slender buildings all t...

11 Thermal comfort in outdoor spaces is strongly associated with the quality of social life 12 in an urban community. This study investigated dynamic outdoor thermal comfort under 13 cold, mild, and hot climatic conditions with air temperature ranging from -0.1 to 35.0 oC. 14 Using a total of 26 human subjects in 94 tests under these climatic conditions, this study 15 measured outdoor thermal e...

Most traditional elementary school classrooms here do not have air-conditioners and it often feel stuffy in classrooms located in the top floors. In addition, traditional classrooms widely have noise problem, so do the open educational classrooms. If the windows and doors are closed to reduce noise, it will result in the phenomenon of stuffiness, which largely prevents the external air entering...
