We demonstrate the retrieval of column-density images of cold atoms, using a noninterferometric phase-recovery technique based on a single off-resonant and defocused intensity image. The quantitative column density is retrieved via Fourier inversion and remains robust with respect to detuning and defocus. The technique offers excellent prospects for simple, nondestructive imaging of atoms in ma...
Considering the challenges in fabrication and electromagnetic characterization of linear accelerator tube, first four major effective parameters in cavity fabrication, including cavity material, dimension agreement, surface roughness and concentricity of cavities have been studied. Then, considering appropriate electromagnetic properties, fabrication results of cavities, techniques for their re...
We consider the inverse problem of in-line holography, applied to minimally destructive imaging of cold atom clouds. Absorption imaging near resonance provides a simple, but destructive measurement of atom column density. Imaging off resonance greatly reduces heating, and sequential images may be taken. Under the conditions required for off-resonant imaging, the generally intractable inverse pr...
Abstract This paper studies the two widely used material models for predicting dynamic behavior of soils, Ramberg-Osgood and Hadrin-Drnevich models. Resonant column torsional simple shear test results on dry sand were to calibrate evaluate model built in finite element software Midas GTS NX. Both are already implemented by software. study estimates ability efficiency both soil coupled with Masi...
