A Novel Reliability Analysis Approach under Multiple Failure Modes Using an Adaptive MGRP Model
Applied Sciences, 2022 In this paper, a novel MRGP-SS method is proposed to deal with the reliability analysis problems under multiple failure modes. First, a random moving quadrilateral grid sampling (RMQGS) method is proposed to improve the randomness and uniformity of ...

Failure Mode Analysis of Carbon Fiber Composite Laminates by Acoustic Emission Signals
Advances in Materials Science and Engineering, 2021 Composite laminates have complex failure modes. In order to investigate the evolution of failure in the composite laminates, this paper performed an experimental study on four laminates with different layups using acoustic emission (AE) technique.

Radial and Nonradial Oscillation Modes in Rapidly Rotating Stars [PDF]
, 2008 Radial and nonradial oscillations offer the opportunity to investigate the interior properties of stars. We use 2D stellar models and a 2D finite difference integration of the linearized pulsation equations to calculate non-radial oscillations.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
