Nonlinear joint model updating using static responses

Advances in Mechanical Engineering, 2016
Nonlinear behavior is often observed in structural joint system due to external loads. A new technique of nonlinear structural joint model updating with static load test results is proposed in this article to investigate the actual behavior of a joint ...

Comparing the results of dynamic analysis (maximum displacement) with approximate method of Iranian seismic code [PDF]

مجله مدل سازی در مهندسی, 2010
Determining structural maximum deformation under earthquake excitation is an important problem in seismic design of structures. There are several approaches in order to estimate an acceptable accurate response for maximum drift of the structure in ...

Nonlinear versus Ordinary Adaptive Control of Continuous Stirred-Tank Reactor

The Scientific World Journal, 2015
Unfortunately, the major group of the systems in industry has nonlinear behavior and control of such processes with conventional control approaches with fixed parameters causes problems and suboptimal or unstable control results.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Nonlinear Static Analysis of an Asphalt Concrete Core Dam dor Comparison of Three Constitutive Models

Archives of Civil Engineering, 2012
The goal of this work is to compare different constitutive models in the nonlinear static characteristic analysis of asphalt concrete core dams. The Duncan E- μ model, Duncan E-B model and double-yield-surface model are three major constitutive models in

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
