Imperfection sensitivity of plates on thermal environment

, 2017
In this paper a thermal buckling of imperfect plates using Layer Wise (LW) plate model [1] is presented. The model assumes layerwise variation of in-plane displacements and constant transverse displacement through the thickness of the plate, non-linear ...

Interactive Buckling of Q420 Welded Circular Tubes under Axial Compression

Advances in Materials Science and Engineering, 2020
Finite element models (FE models) of high-strength steel Q420 (yield strength 420 MPa) circular tubes considering residual stresses and local and overall geometric imperfections were established and verified against existing test data. Based on parameter

Maximum ratio combining of correlated diversity branches with imperfect channel state information and colored noise [PDF]

Eighth IEEE International Symposium on Spread Spectrum Techniques and Applications - Programme and Book of Abstracts (IEEE Cat. No.04TH8738), 2005
Recently, an analytical expression for the mean bit error probability of a binary modulated signal has been derived for a receiver performing maximum ratio combining of correlated diversity branches based on imperfect channel state information. We extend these results to the general case of colored additive noise.

Clinical, Histologic, and Serological Predictors of Renal Function Loss in Lupus Nephritis

Arthritis Care &Research, EarlyView.
Objective Kidney survival is the ultimate goal in lupus nephritis (LN) management, but long‐term predictors remain inadequately studied, requiring long‐term follow‐up. This study aimed to identify baseline and early longitudinal predictors of kidney survival in the Accelerating Medicines Partnership LN longitudinal cohort.

Plastic buckling of initially imperfect stiffened cylinders in axial compression [PDF]

, 1981
Bibliography: leaves 117-118.Bifurcation in the plastic range of axially compressed stringer-stiffened cylinders is investigated. The shell under consideration is assumed to have an initial imperfection in the form of a sinusoidal deviation both axially ...

Fatigue Strength Assessment of Welded Mild Steel Joints Containing Bulk Imperfections

Metals, 2018
This work investigates the effect of gas pores, as bulk imperfections, on the fatigue strength of welded mild steel joints. Two test series containing different butt joint geometries and weld process parameters are included in order to achieve two ...

Flutter Measurement of a Linear Turbine Blade Cascade with an Angular Position Deviation of One Blade

Journal of Mechanical Engineering, 2023
Experimental flutter testing of high-aspect ratio rotor blades is a mainstay of turbomachinery research. However, rotor blades are never identical, and geometrical errors between actual and nominal geometries exist due to limited machining precision or ...

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

Arthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Imperfection investigation of composite stiffened fuselage panels for Postbuckling analyses [PDF]

, 2008
Project COCOMAT is an ongoing four year European Commission project aimed at exploiting the large reserve of strength in composite structures through more accurate prediction of collapse. As part of the research program, curved stiffened composite panels

Robust Entangled-Photon Ghost Imaging with Compressive Sensing

Sensors, 2019
This work experimentally demonstrates that the imaging quality of quantum ghost imaging (GI) with entangled photons can be significantly improved by properly handling the errors caused by the imperfection of optical devices.
