We demonstrate a new method for dynamical parametric simulation of MEMS using IZ-optimal designs for FEA simulations, fitting using the best linear unbiased predictor, and extraction of relevant coefficients for solution of the appropriate ODE using T-SPICE. A five-factor microaccelerometer example demonstrates that highly accurate dynamical simulations are possible, in some cases, using a very...

Zernike polynomials are an orthogonal set over a unit circle and are often used to represent surface distortions from FEA analyses. There are several reasons why these coefficients may lose their orthogonality in an FEA analysis. The effects, their importance, and techniques for identifying and improving orthogonality are discussed. Alternative representations are presented.

The distinction between tubular carcinomas (TC) and invasive well-differentiated (grade 1) ductal carcinoma (IDC) is important given treatment and prognostic differences. Studies have described a strong association between flat epithelial atypia (FEA) and TC. The incidence of FEA associated with grade 1 IDC is not well established. The aim of the present study was to assess morphology and intra...

This paper studies the security of an improved fast encryption algorithm for multimedia (FEA-M). A simple differential chosen-plaintext attack is proposed to completely break the improved FEA-M. The proposed attack is very efficient in complexity and needs only two pairs of chosen plaintext blocks.

OBJECTIVE The aim of this in vitro study was to determine the load and deflection at failure of different lingual retainers bonded with composite to enamel in a standardized three-point bending test. The results were rationalized with finite element analysis (FEA) models. MATERIALS AND METHODS Four types of multistranded wires, Dead Soft Respond, Twisted ligature, Penta-One, Gold-plated Penta...

The course MECH625-simulation-based design in our program was mainly to conduct FEA (Finite Element Analysis) on components and assemblies to provide stress/strain information. Through our program assessment, it was found that students who performed excellently in the previous MECH625 course had some difficulties incorporating FEA simulation correctly and efficiently on their senior design proj...

A meeting in Vienna in October 2010 brought together researchers using Virtual Anthropology (VA) and Finite Element Analysis (FEA) in order to explore the benefits and problems facing a collaboration between the two fields. FEA is used to test mechanical hypotheses in functional anatomy and VA complements and augments this process by virtue of its tools for acquiring data, for segmenting and pr...

Abstract A Problem Solving Environment for the finite element method (FEM-PSE) is an application system to support users pursuing a career in the finite element analysis (FEA). There are two types of users associated with the FEA. One is analysis-user who uses application software of the FEM and the other is development-user who develops application software of the FEM. We used an abstraction t...

THE JOURNAL OF PROSTHETIC DENTISTRY 585 In the past 2 decades, finite element analysis (FEA) has become an increasingly useful tool for the prediction of the effects of stress on the implant and its surrounding bone. Vertical and transverse loads from mastication induce axial forces and bending moments and result in stress gradients in the implant as well as in the bone. A key factor for the su...
