This paper introduces a new concept of integrating artificial neural networks (ANN) and genetic algorithms (GA) in modeling the deflection basins measured on the flexible pavements. Backcalculating pavement layer moduli are well-accepted procedures for the evaluation of the structural capacity of pavements. The ultimate aim of the backcalculation process from Nondestructive Testing (NDT) result...

Beam-beam deflection scan is a useful tool, both in the SLC and in future linear colliders, for extracting information about the beam position, .w size and luminosity. This technique poses nontrivial challenges to the instrumentation in its own right. The understanding of all aspects of beam-beam deflection, in particular that of disruption, is therefore crucial to a successful implementation o...

Remote and robotically actuated catheters are the stepping-stones toward autonomous catheters, where complex intravascular procedures may be performed with minimal intervention from a physician. This article proposes a concept for the positional, feedforward control of a robotically actuated cell injection catheter used for the injection of myogenic or undifferentiated stem cells into the myoca...

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...

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...
