We report the first direct observation of the electromagnetic deflection of high --energy electron and positron beams as they pass each other with small impact _. -parameters. ‘Measurements of the deflection amplitude are found in agreement with theoretical expectations. This phenomenon, which is sensitive both to the relative position of the two beams and to their transverse sizes, has been us...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

In this paper, the vibration of microbeams due to a temperature pulse has been investigated. The thermoelastic coupled equations for microbeam resonator have been derived via the modified theory of couple stress in connection with the generalized thermoelasticity with relaxation time. The analytical expressions for studied fields due to modified couple stress for the microbeam have been obtaine...

Optical packet-switched networks of the near future will likely use no or very small number of optical buffers. We compare the delay-throughput performance of deflection routing and optical burst switching because both do not require the use of optical buffers. Simulations show that the simple packet drop-andretransmit contention resolution strategy of optical burst switching has a better perfo...

In this study, a semi analytical method for transverse and axial vibration of single-walled boron nitride nanotube (SWBNNT) under moving a nanoparticle is presented. The surrounding elastic medium as Pasternak foundation and surface stress effect are included in the formulations of the proposed model. Using Timoshenko beam theory (TBT), Hamilton’s principle and nonlocal piezoelasticity theory, ...

In this paper, nonlinear static analysis of moderately thick plate made of functionally graded materials subjected to mechanical transverse loading is carried out using dynamic relaxation method. Mindlin first order shear deformation theory is employed to consider thick plate. Discretized equations are extracted for geometrically nonlinear behavior analysis.Loading Conditions and boundary condi...

In scanning display systems, high horizontal and vertical resolution, and high refresh rate requirements translate into large mirror-size scan-angle product and high scanner-frequency requirements. A comparison between published scan-angle mirror-size product values for MEMS scanners and a Steel mechanical scanner is presented. Current performance levels of Steel mechanical scanners are better;...

We compute the deflection angle for a light ray traveling in a flat ΛCDM cosmology which encounters a completely condensed mass region to second order inm/r0 and first order inm/r0×Λr 2 0.We find that the most significant correction to the Einstein angle occurs not because of the non-linear terms but instead because the condensed mass is embedded in an expanding cosmology. We predict a decrease...
