RESEARCH ON FREE VIBRATION FREQUENCY CHARACTERISTICS OF ROTATING FUNCTIONALLY GRADED MATERIAL TRUNCATED CONICAL SHELLS WITH ECCENTRIC FUNCTIONALLY GRADED MATERIAL STRINGER AND RING STIFFENERS

Abstract In this research work, an exact analytical solution for frequency characteristics of the free vibration of rotating functionally graded Heat Protectant material (FGM) truncated conical shells reinforced by eccentric FGM stringers and rings has been investigated by the displacement function method.Material properties of shell and stiffeners

Abstract Most existing production vehicle tracking services rely on the Global Positioning System (GPS) and a proprietary server/client infrastructure.This type of inflexible and centralized architecture incurs severe vender-dependency and high service cost.In this paper, we propose a cost-effective decentralized vehicle remote positioning and trac

Coccidioides spp.are dimorphic pathogenic fungi whose parasitic forms cause coccidioidomycosis (Valley fever) in mammalian hosts.We use an innovative interdisciplinary approach to analyze one-on-one encounters between human neutrophils and two forms of Coccidioides posadasii.To examine the mechanisms by which the innate immune system coordinates di
