Residual welding stress of I-section members beyond the limits of width-thickness ratio [PDF]
Fracture and Structural Integrity, 2017 Despite the extensive studies on the effect of width-thickness ratio and residual stress on member behavior, few scholars have probed into the residual stress distribution on the I-section members.

RESEARCH ON SHOT STRESS RELAXATION MODEL OF2024-T351 ALUMINUM ALLOY
Jixie qiangdu, 2021 The residual compressive stress field introduced by shot peening can effectively improve the fatigue performance of the component, but decrease of the residual compressive stress cased by the cycle stress relaxation, thereby reducing the gain effect of ...

MMWR. Morbidity and mortality weekly report, 2021 Rapid antigen tests, such as the Abbott BinaxNOW COVID-19 Ag Card (BinaxNOW), offer results more rapidly (approximately 15-30 minutes) and at a lower cost than do highly sensitive nucleic acid amplification tests (NAATs) (1).

Consistent GMM Residuals-Based Tests of Functional Form [PDF]
Econometric Reviews, 2011 This paper presents a consistent GMM residuals-based test of functional form for time series models. By relating two moments we deliver a vector moment condition in which at least one element must be non-zero if the model is mis-specified. The test will never fail to detect mis-specification of any form for large samples, and is asymptotically chi ...

MATEC Web of Conferences, 2016 The redistribution of residual stress appears with the propagation of internal crack or damage, which also has an influence on the fatigue life of structure. A prediction model of residual stress redistribution is raised based on the Hull - Rimmer theory.

A Novel Approach for Testing Fractional Cointegration in Panel Data Models with Fixed Effects
Fractal and FractionalFractional cointegration in time series data has been explored by several authors, but panel data applications have been largely neglected. A previous study of ours discovered that the Chen and Hurvich fractional cointegration test for time series was ...

High-temperature oxidation of nickel-based alloys and estimation of the adhesion strength of resulting oxide layers [PDF]
, 2011 The kinetics of isothermal oxidation (1100°C) of commercial nickel-based alloys with different content of sulfur (0.22–3.2 wt ppm) is studied. The adhesion strength in a metal/oxide system is estimated as a function of sulfur content and duration of high-
