An approximate analysis of the transient and steady state behavior of deflection routing in hypercube networks is presented, under a uniform traffic model. In deflection routing congestion causes packets admitted to the network to be temporarily misrouted rather than buffered or dropped. Our approximations show that deflection routing performs remarkably well in hypercube networks, for small as...
Deflection of protons under axial channeling in a silicon crystal bent along the <111> axis was observed on experiment with 400-GeV protons at the CERN Super Proton Synchrotron. The deflection efficiency due to axial channeling of protons for the crystal with the bend angle 50 μrad was about 30 %. Axial channeling deflection occurred by means of doughnut scattering and hyper-channeling, this la...
in this paper, a monotone positive solution is studied for buckling of a distributed model of multi walled carbon nanotube (mwcnt) cantilevers in the vicinity of thin and thick graphite sheets subject to intermolecular forces. in the modeling of intermolecular forces, van der waals forces are taken into account. a hybrid nano-scale continuum model based on lennard–jones potential is applied to ...
An experimental study was performed to investigate the effects of the body angle of attack on the tail surface pressure distribution for a half body-tail combination in subsonic flow. The results show, in small deflection angle regions, that the tail deflection has the same effect on the surface pressure as the body angle of attack. However at moderate to high deflections, the flowfiled caused ...
Cutting force has a significant influence on the dimensional accuracy due to cutting toolholder deflection. The problem of tool holder deflection is faced frequently in a variety of engineering surface products, and to achieve this goal passive technique can be used. The need for passive technique arises from the complexities that brought to the structures by active control techniques and energ...
This report describes the development of a prototype system that is capable of monitoring the deflection of a bandsaw blade during wood sawing process. The deflection is caused by tension loss of the saw blade and leads to downgrading and value loss of timbers. A CCD-type laser triangulation sensor has been proposed to monitor the saw blade deflection. Deflection monitoring has to be done in re...
This study evaluated the mechanical performance of teardrop-shaped loops and teardrop-shaped loops with helix used in orthodontic space closure. Sixty retraction loops made with 0.019" x 0.025" stainless steel (SS) and beta-titanium (BT) wires were used. They were attached to a testing machine to measure the magnitudes of the sagittal force and the load-deflection ratio necessary for 1 mm, 2 mm...
Contention is the main source of burst loss in Optical Burst Switched (OBS) networks where deflection routing is one of the methods to resolve contention. Deflection routing requires enhancements only in the routing software without additional hardware installations. Its main goal is to successfully deflect a burst based only on a limited knowledge that nodes posses about their environment. In ...
An idea for enabling all-optical packet switched networks is to use deflection routing together with erasure recovery coding at the packet level. Deflection routing has been generally considered in the past only in highly structured networks. The purpose of this paper is to report results of a simulation experiment to evaluate several topology-based routing algorithms for deflection routing in ...
We improve the precision of the interferometric weak-value-based beam deflection measurement by introducing a power recycling mirror, creating a resonant cavity. This results in all the light exiting to the detector with a large deflection, thus eliminating the inefficiency of the rare postselection. The signal-to-noise ratio of the deflection is itself magnified by the weak value. We discuss w...
