This paper focuses on the development of a complete model of an atomic force microscope (AFM) micro-cantilever beam, based on considering the effects of four major factors in modeling the cantilever. They are: rotary inertia and shear deformation of the beam and mass and rotary inertia of the tip. A method based on distributed-parameter modeling approach is proposed to solve the governing equat...

R f search has produced two major procedures for assessing creep and shrinkage; the ACI 209 method' and the CE$-FJP method.' Laboratory research into concrete creep and shrinkage has been conducted for decades, and excellent analytical procedures for evaluating structures for creep and shrinkage have been presented in the literature.'-5 Creep and shrinkage are factors in the design of a variety...

This study selected forty-two implants with full arch implantsupported fixed prostheses (with and without a cantilever) with at least five years' loading. Radiographic measurements were performed using Digimizer software (MedCalc Software, Belgium). Bone loss was measured on the distal side of the implant, from the surface of the platform to the edge of the bone crest, and the extent of the can...

Abstract Based on the reconstruction and expansion project of an expressway, a set rapid construction technology for integrated erection fully prefabricated rigid frame bridges is proposed, which solves problems unmatched work efficiency each working face in conventional bridge erectors long period traditional suspension assembly technology. This method realizes this type highly urbanized areas...

Lemah Ireng II Bridge is a type of box girder balance cantilever bridge located in Semarang Regency, Central Java, which was completed 2014. The renewal loading regulations 2016 consisted SNI 1725:2016 for standard load and 2833:2016 earthquake load. Changes resulted an increase the ground surface spectra value short period (Sds, T=0,2 second) longitudinal direction by 38.47% transverse 45.39% ...

We present a simple technique to produce active Qswitching in various types of fiber amplifiers by active integration of an electrostatic actuated deformable metallic micro-mirror. The optical MEMS (MOEMS) device acts as one of the laser cavity reflectors and, at the same time, as switching/ modulator element. We aim to obtain laser systems emitting short, high-power pulses and having variable ...

one of the bio-sensing mechanisms is mechanical. rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. this study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on silicon wafer, with the ...
