In this study, free and forced vibration responses of carbon nanotube reinforced uniform tapered composite beams are investigated. The governing differential equations motion a (CNT) presented in finite element formulation. validity the developed formulation is demonstrated by comparing natural frequencies evaluated using present FEM with those available literature. Various parametric studies a...

the most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy by the effect of coupling between electric fields and mechanical variables. using piezoelectric cantilevers is the most common method for vibration energy harvesting. changing the shape of the cantilevers can lead to changing the generated output v...

Whispering Gallery Mode resonators are dielectric structures with cylindrical symmetry. They typically excited an evanescent field leaking out of a tapered fiber or waveguide. It is also known that they can be free propagating beams. In this work, we use recently developed analytical model which quantitatively describes the coupling beams into Modes for spherical particles. Using model, have be...

We study the expected performance of the proposed fundamental neutron physics beamline at the upgraded High Flux Isotope Reactor at Oak Ridge National Laboratory. A curved neutron guide transmits the neutrons from the new cold source into a guide hall. A novel feature of the proposed guide is the use of vertical focussing to increase the flux for experiments that require relatively small cross-...
