Test of Qed at Critical Field Strength
In a new experiment at the Final Focus Test Beam at SLAC a low-emittance 46.6-GeV electron beam is brought into collision with terawatt pulses of 1054 nm or 527 nm wavelength from a Nd:glass laser. Peak laser intensities of 10 W/cm have been achieved corresponding to a value of 0.6 for the parameter = eE=m!0c. In this case an electron that crosses the center of the laser pulse has near-unit int...
متن کاملNumerical Solution of Fence Performance for Reduction of Sand Deposition on Railway Tracks
Movement of sand particles in nature creates many problems for humans. One of these problems is deposition of particles on rails that decrease the speed of the train or in some cases hampers the reversal of the train rails. In this paper the motion of sand particles over a railway track embankment, and how these particles settle on railway tracks are investigated. Moreover,the performance of di...
متن کاملAcceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...
متن کاملEffect of Constructing Canal in Embankments on Sand Flow through Railway Tracks in Desert Regions
Entry of sand dunes into the railway tracks can result in sand deposition on tracks, railway obstruction, derailment, damage to track flexibility, and impairment of electrical signs and rail fleet. It is aimed to investigate the strategies and solutions for reducing sand aggregation on railway tracks (including construction of sand passage canals through embankments and modification of the geom...
متن کاملPerceptual constancy in auditory perception of distance to railway tracks.
Distance to a sound source can be accurately estimated solely from auditory information. With a sound source such as a train that is passing by at a relatively large distance, the most important auditory information for the listener for estimating its distance consists of the intensity of the sound, spectral changes in the sound caused by air absorption, and the motion-induced rate of change of...
