in this article, the bending and free vibration analysis of functionally graded (fg) nanocomposites timoshenko beam model reinforced by single-walled boron nitride nanotube (swbnnt) using micro-mechanical approach embedded in an elastic medium is studied. the modified coupled stress (mcst) and nonlocal elasticity theories are developed to take into account the size-dependent effect. the mechani...

the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...

Introduction: The present study evaluated the dosimetric comparison between 6MV flattened filter (FF) and flattening filter-free (FFF) photon beams in intensity-modulated radiation therapy (IMRT) technique for the treatment of glioblastoma (GBM) patients. Material and Methods: The present study was conducted on 10 patients with GBM previously...

This article is devoted to electron beam distortions in the “electron compressor” setup for beam-beam compensation in the Tevatron collider. The distortions are due to interaction of the electron beam with impacting elliptical antiproton beam. We estimate of longitudinal magnetic field necessary to keep the distortions low.

This contribution presents the extensions of beam-to-beam and beam-inside-beam contact schemes same authors towards frictional interactions. Since are based on beams' true surfaces (instead implicitly deduced from centroid lines), presented enhancements not only able to account for sliding in axial directions, but also circumferential directions. Both approach as well applicable shear-deformabl...

the present study is the first to analyze the dynamic response of a poroelastic beam subjected to a moving force. moreover, the influences of attached mass-spring systems and non-ideal supports (with local movements in the supporting points or base due to the presence of factors such as gaps, unbalanced masses, and friction or seismic excitations) on the responses were investigated. non-ideal s...

Background: This study aims to investigate radiation beam geometry of Cyberknife beam and change in dosimetric characteristics of six megavoltage (6MV) flattening filter free (FFF) beam after passing through high density cadmium free compensator alloy.Material and Methods: In this experimental study, changes in FFF beam dosimetric characteristics after passing through compensator alloy wa...

SLAC-PUB-6379 October 1993 W Simulation of the Beam Halo from the Beam-Beam Interaction T. Chen, J. Irwin and R. Siemannt Stanford Linear Accelerator Center, Stanford University, Stanford, CA94309 Abstract: A new technique for simulating the beam halo in circular e+ecolliders is introduced, tested, and applied. Amplitude space is divided into core and halo regions, and only halo particles are t...

However, John Rees has pointed out that the above reference is incorrect. The dynamic p was realized a few years later, and the correct references are: 15. F. Amman, R. Andreani, M. Bassetti, M.
