Current mobile computing systems can automatically sense and communicate detailed data about a person’s location. Location privacy is an urgent research issue because concerns about privacy are seen to be inhibiting the growth of mobile computing. This paper investigates a new technique for safeguarding location privacy, called obfuscation, which protects a person’s location privacy by degradin...

The high efficiency of monocoque cylindrical shells in carrying axial loads is curtailed by their extreme sensitivity to imperfections. For practical applications, this issue has been alleviated by introducing closely stiffened shells which, however, require expensive manufacturing. Here we present an alternative approach that provides a fundamentally different solution. We design symmetry-brea...

Wabi sabi is one of Philosophy in Japan. It’s about appreciation to the beauty imperfection. can be found so many aspects Japanese people’s life such as chanoyu, ikebana, haiku, or fairytale children. This article aims know how oldman gets spirit by wabi cheer his life. Hanasaka Jiisan used this research a source data. The result appeared oldman’ house, falling leaves, dead trees, and flowers. ...

Abstract This paper presents an investigation on the influence of structural imperfections ultimate load capacity steel welded beam-columns with class 4 cross-section under elevated temperatures. is done by considering different amplitudes for global and local (plate) imperfections, residual stresses distributions available in literature. To this purpose, a geometrically materially non-linear f...

Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...
