Abstract This paper presents the experimental analysis of vulcanization process nitrile rubbers for diaphragms fabrication used in FBG-based pressure sensors. Tests using with different rubber thicknesses (0.5mm, 1.0mm, and 1.5mm), temperatures (125°C, 150°C, 200°C), times (2.5min 5.0min) were performed to analyse chemical degradation diaphragms. Degradation was digital macrography diaphragm su...

One of the most important assumptions which is being used in analysis and design of buildings against lateral forces is the rigid-floor assumption. Lateral rigidity of diaphragms depends on several factors such as: type of the structure, dimensions of structure, rigidity and location of lateral load bearing elements, stiffness of frames, type and thickness of floors, number of stories and etc. ...

For quite a while architects have been dreaming of architecture that can change its appearance. The motivation for such a change ranges from rational adaptation to environmental variation according to a time of day, season, or temperature, to pure aesthetics and ordinary commercialism. One of the most recognized examples is Jean Nouvel’s Arab World Institute in Paris, where 30 000 light-sensiti...
