In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are cou...

Pressure measurements in industries, biomedical and marine environment are of utmost importance to better understand the process stability, ocean processes. The influence of in-plane stresses of silicon plate with square, rectangular and circular shape have been investigated. The area of square, rectangular and circular form of elastic element has been approximated to be equal and the thickness...

The study presented in this paper builds upon previous research into system identification using multiple models at EPFL. This identification methodology is based on the selection of sets of candidate models such that differences between measurements and their predictions are below a certain threshold value. The threshold value is a function of modeling and measurement errors. This paper presen...

Transcription activation by the Escherichia coli cyclic AMP receptor protein (CRP) at different promoters has been studied using RNA polymerase holoenzyme derivatives containing two full-length alpha subunits, or containing one full-length alpha subunit and one truncated alpha subunit lacking the alpha C-terminal domain (alpha CTD). At a promoter having a single DNA site for CRP, activation req...

In this study, a finite element model of a tissue-mimicking, viscoelastic phantom with a stiffer cylindrical inclusion subjected to an acoustic radiation force (ARF) is presented, and the resulting shear waves through the heterogeneous media are simulated, analyzed, and compared with experimental data. Six different models for the ARF were considered and compared. Each study used the same finit...

A finite element automobile model for use in crash safety studies was developed through reverse engineering. The model was designed for calculating the response of the automobile structure during full frontal, offset frontal, or side impacts. The reverse engineering process involves the digitization of component surfaces as the vehicle is dismantled, the meshing and reassembly of these componen...

In this paper, we propose an optimal design approach based on a concept of mosaic-like structure for achieving high performance NRD devices. order to improve efficiency, employ the recently proposed two-dimensional full vectorial finite element method (2D-FVFEM) which can accurately model 3D as numerical simulation method. As optimization method, either direct binary search (DBS) algorithm or g...

a new modified adomian decomposition method (adm) is utilized to obtain an analytical solution for buckling of the nanocantilever actuators immersed in liquid electrolytes. the nanoactuators in electrolytes are subject to different nonlinear forces including ionic concentration, van der waals, external voltage and electrochemical forces. the duan–rach modified adomian decomposition method is ut...
