Damage and Fatigue Life Evaluation for Laser Cladding Remanufactured Wheel

open access: yesAdvances in Materials Science and Engineering, 2022
Owing to high speeds and heavy loads, the wheels of trains and locomotives undergo gradual but significant damage. Conventionally, these damaged wheels are repaired using the rotatory repair method; however, this approach results in large amounts of ...

Global Trends of Mean and Inequality in Multidimensional Wellbeing: Analysis of 1.2 Million Individuals From 162 Countries, 2009–2019

open access: yesFrontiers in Public Health, 2022
IntroductionHuman flourishing is a multidimensional concept characterized by a state of complete wellbeing. However, much of the prior research on wellbeing has principally focused on population averages assessed using a single item of wellbeing.

Evaluating Life Expectancy Evaluations [PDF]

open access: yesNorth American Actuarial Journal, 2017
The quality of life expectancy estimates is one key consideration for an investor in life settlements. The predominant metric for assessing this quality is the so-called A-to-E ratio, which relies on a comparison of the actual to the predicted number of deaths.

Evaluating Biosignatures for Life Detection [PDF]

open access: yesAstrobiology, 2020
Conceptual frameworks are developed for evaluating the ability of different biosignatures to provide evidence for the presence of life in planned missions or observational studies. The focus is on intrinsic characteristics of biosignatures in space environments rather than on their detection, which depends on technology. Evaluation procedures are drawn

Service Life Evaluation for RC Sewer Structure Repaired with Bacteria Mixed Coating: Through Probabilistic and Deterministic Method

open access: yesMaterials, 2021
Since a concrete structure exposed to a sulfate environment is subject to surface ion ingress that yields cracking due to concrete swelling, its service life evaluation with an engineering modeling is very important.

An orientation-dependent creep life evaluation method for nickel-based single crystal superalloys

open access: yes, 2021
This paper aims to propose a creep life evaluation method considering the effect of crystallographic orientation. First, the maximum Schmid factor of {111} and the corresponding lattice rotation angle were introduced to form an “orientation factor”. Then

Research Status and Advances in Cryogenic Crack Propagation of Aeronautic Aluminium-alloys

open access: yesHangkong gongcheng jinzhan, 2020
Aluminium-alloys are widely used in aeronautical engineering due to the advantages of high strength and easy processing. Low temperature inevitably occurs in aero-structures of aluminium-alloys, and cryogenic crack propagation of aeronautic aluminium ...

Aging Life Evaluation of Coal Mining Flexible EPR Cables Under Multi-Stresses

open access: yesIEEE Access, 2020
As important power cables for the mining mobile equipment, such as mining shearers, ethylene propylene rubber (EPR) cables often suffer from the combining effect of various stresses on site.

Evaluation of multiaxial low cycle fatigue life under non-proportional loading considering effect of mean strain (Loading simulated thermal fatigue due to temperature fluctuation in junction piping)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
In a pressure vessel, a heat exchanger and a junction piping where cold and hot water are mixed, temperature fluctuation yields multiaxial stress and random amplitude loading conditions.

Common Objects in 3D: Large-Scale Learning and Evaluation of Real-life 3D Category Reconstruction [PDF]

open access: yesIEEE International Conference on Computer Vision, 2021
Traditional approaches for learning 3D object categories have been predominantly trained and evaluated on synthetic datasets due to the unavailability of real 3D-annotated category-centric data.
