We study the applicability of beam-beam deflection techniques as a tuning tool for the SLAC/LBL/LLNL B factory, PEP-II. Assuming that the closed orbits of the two beams are separated vertically at the interaction point by a local orbit bump that is nominally closed, we calculate the residual beam orbit distortions due to the beam-beam interaction. Difference orbit measurements, performed at poi...
Microcantilever sensors offer high sensitivity in the detection of adsorbed molecules based either on resonance frequency shift or changes in cantilever deflection, as both of these signals can be detected with very high resolution. Despite the high sensitivity offered by this platform, cantilevers suffer from poor selectivity due to the lack of sufficiently selective interfacial layers which c...
We report two-dimensional density measurements in a supersonic expansion using beam-deflection optical tomography. Quantitative, high-resolution images with absolute accuracy to 3.5% and spatial resolution to 50 microm were taken with a helium-neon laser and simple apparatus.
In this paper, the elastic behaviour in bending of three-layer plywood cantilever beams is analysed. Deflections straight and half-circle cantilevers, loaded with a force at free end determined experimentally calculated using analytical finite element method approach. The calculation deflection for strait obtained transformed cross section. by classical laminated plate theory Castigliano’s theo...
For the first time, measurements of the cosmic microwave background radiation (CMB) alone favor cosmologies with w = -1 dark energy over models without dark energy at a 3.2-sigma level. We demonstrate this by combining the CMB lensing deflection power spectrum from the Atacama Cosmology Telescope with temperature and polarization power spectra from the Wilkinson Microwave Anisotropy Probe. The ...
A diagrammatic reasoning for structural analysis on trusses is proposed and demonstrated on many examples . In the reasoning, deflected shape of a substructure is drawn at first then it is reasoned how the remaining substructure is affected by the deflection . By identifying the elongated parts are in tension and shortened parts are in compression, a qualitative stress analysis can be done diag...
A numerical and experimental analysis of the optical beam deflection system used to monitor microcantilevers subjected to simultaneous deflection and twisting such as in lateral or frictional force microscopy was performed. This study focused on two optical beam deflection orientations where in the first case the optical beam and the detector are at a right angle to the length of the cantilever...
The objective of this work is to study the large deflection of geometrically asymmetric metal foam core sandwich beam under transverse loading by a fiat punch. A yield criterion is proposed for geometrically asymmetric metal foam core sandwich structures, and then analytical solution for the large deflection of a fully clamped slender sandwich beam is obtained, in which the interaction of bendi...
