Uncertainty quantification and sensitivity analysis of a nuclear thermal propulsion reactor startup sequence

Frontiers in Nuclear Engineering
The research presented in this article describes progress in applying stochastic methods, uncertainty quantification, parametric studies, and variance-based sensitivity analysis (also known as Sobol sensitivity analysis) to a full-core model of a nuclear

The influence of realistic 3D viscous mean flow on shielding of engine-fan noise by a 3-element high-lift wing [PDF]

, 2010
The prediction of aeroacoustic shielding often rests on tools using constant mean flow thus neglecting mean flow inhomogeneities such as shear layers. This study analyses the influence of this simplification on shielding.

Durability assessment of mechanochemically activated geopolymer concrete with a low molarity alkali solution

Case Studies in Construction Materials
The prevailing practices of geopolymer concrete (GC) preparation use a high concentration of alkali activators, which is uneconomical. It is imperative to develop GC of low-concentration activators with enhanced durability for field implementation ...

A numerical study of crack shielding and deflection under extensive plasticity [PDF]

, 2009
Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

To shield or not to shield: shielding may have unintended effects on patient dose in CT

European Radiology, 2023
Abstract Objectives The aim of the patient out-of-plane shield is to reduce the patient radiation dose. Its effect on tube current modulation was evaluated with the out-of-plane shield visible in the localizer but absent in the scan range in chest CT with different CT scanners. Methods

Numerical and experimental analysis of thermal behaviour of high voltage power cable in unfilled ducts

Scientific Reports
The work addresses the topic of the thermal study of high-voltage power cables installed inside plastic pipes in the absence of filling. The presence of air inside the pipe creates an insulating layer that does not favor heat exchange and makes the ...

The ATLAS SCT grounding and shielding concept and implementation [PDF]

, 2012
This paper presents a complete description of Virgo, the French-Italian gravitational wave detector. The detector, built at Cascina, near Pisa (Italy), is a very large Michelson interferometer, with 3 km-long arms. In this paper, following a presentation
