Employing an atomic force microscope (AFM) in conjunction with a quartz crystal microbalance, we have investigated how a high-frequency lateral oscillation of the substrate influences the imaging process of the AFM. It was found that the time-averaged deflection of the cantilever (both vertical and lateral) changed when the oscillation of the quartz resonator was turned on. The vertical-tip-sub...

In this paper at first introduced constituent equations for piezoelectric and then by the help of this equations, internal energy of hinged-hinged piezoelectric multilayer beam was computed. Then by the principle of minimum potential energy and Rayleigh -Ritz method the bending curvature equation of hinged-hinged piezoelectric multilayer beam under concentrated moment, concentrated force, unifo...

The analysis of the static deflection of cantilever plates is of fundamental importance in application to the atomic force microscope (AFM). In this paper we present a detailed theoretical study of the deflection of such cantilevers. This~ shall incorporate the presentation of approximate analytical methods applicable in the analysis of arbitrary cantilevers, and a discussion of their limitatio...

This work presents geometrically non-linear static analysis of a cantilever beam subjected to a non-follower transversal point load at the free end of the beam. The material of the beam is assumed as isotropic and hyperelastic. In this study, finite element model of the beam is constructed by using total Lagrangian finite element model of two dimensional continua for a twelve-node quadratic ele...

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.

Toward the general goal ofpreventing ankle injuries in snowboarding accidents, the E. Wang objective of this project to develop a dynamic system model of a snowboarder and Assistant Professor, assess which model parameters, particularly those attributed to the boot, most Department of Mechanical Engineering, strongly influenced ankle deflections during a forward fall. To satisfy this objective,...

Multicasting in deflection networks is more difficult than in store-and-forward networks, because of the difficulties in sending multiple copies of the same packet on several output ports. On the other hand, deflected packets stray from their optimal paths and may visit the multicast recipients “accidentally,” not necessary in the order envisioned by the sender. We compare a number of simple mu...

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 ...

Nanocantilevers have become key components of nanomechanical sensors that exploit changes in their resonant frequencies or static deflection in response to the environment. It is necessary that they can operate at a given, but adjustable, resonant frequency and/or static deflection ranges. Here we propose a new class of nanocantilevers with a significantly tunable spectrum of the resonant frequ...
