The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

Background: To compare the loss of preload in absence loading and after a fixed number cyclic loadings on 7-mm distal cantilever two different connection systems using all-on-four prosthetic model. Methods: Two equal models an edentulous mandible rehabilitated with technique types abutment system (MUA OT-Bridge) supporting hybrid prosthesis, were used. Initial torque values fixing screw, ten mi...

Abstract The box girder of the Miaoziping Bridge, a three-span prestressed concrete continuous rigid-frame bridge, suffered serious crack in its section’s web near 1/6 to 1/2 length side span and middle-span 1/4 3/4, as result 2008 Wenchuan earthquake, which also caused large lateral residual displacements at both ends span. In this study, eight strong-motion records bridge site two other (El C...

Abstract: To cure imperfections such as low accuracy and the lack of ability to nucleate hole in the conventional level set-based topology optimization method, a novel method using a trapezoidal method with discrete design variables is proposed. The proposed method can simultaneously accomplish topology and shape optimization. The finite element method is employed to obtain element properties a...

Although dental implants have been successfully used for the rehabilitation of fully edentulous and partially edentulous patients, patient’s various conditions constrict the application of implant, or make dental treatment using dental implants very complex and difficult. Implantsupported cantilever prostheses represent that conditions. Becker and Kaiser insisted that alignment problems, extens...

In order to better control the safety risk of bridge construction, this paper takes cantilever construction sanduizi super large on Jinshajiang River as an example, and establishes prediction model by using Bayes principle. Firstly, it constructs relationship environmental factors key process events, then uses theory analyze probability events in various cases. Finally, overall influence degree...

The John F. KennedyMemorial Bridge, a large cantilever through truss opened in 1963, carries Interstate 65 across the Ohio River between Louisville, Kentucky and Jeffersonville, Indiana. According to a 2003 count, the bridge carries over 120,000 vehicles per day [1]. Inspections revealed a five-inch full-depth transverse crack in the horizontal web in a tension region of the top chord on the ea...

Title of Thesis: EMBEDDED STRAIN SENSOR WITH POWER SCAVENGING FROM BRIDGE VIBRATION Ming Wang, Master of Science, 2004 Thesis directed by: Professor Peter C. Chang Department of Civil Engineering The Objective of this thesis is to investigate an embedded strain sensor system with power scavenged from highway bridge vibration for structure health monitoring. A power scavenging scheme is develope...

Micromechanical cantilevers show great potential as highly sensitive biochemical sensors. Cantilever-based sensing involves the transduction of a biomolecular interaction to a measurable mechanical change in the cantilever resulting from induced surface stresses added mass. In surface stress sensing applications, one side of the cantilever beam is rendered sensitive to a specific target molecul...

S.Z. cantilevers are made using a simple one-mask fabrication process with.characterization of a cantilever-type MEMS chemical sensor for detection of chemicals. MEMS has been with the advancement of cantilever-type sensors.sensor. The mechanical structure is a cantilever, having its own resonant frequency. MEMS cantilevers can be as thin as a few nanometers with lengths.Cantilever-based Sensor...
