Micro Drilling Simulation of Ultra-Short Pulsed Laser Ablation of Glass [PDF]

open access: yes, 2015
The purpose of this study is to estimate ablated crater depth with sufficient numerical accuracy when multishot channels of ultra-short pulsed laser are executed formicro drilling processes on thin glass plates. In this analytical model, the plasma model,

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

CL Lift Coefficient

open access: yes, 2008
The component integration of a class of hypersonic high-lift configurations known as waveriders into hypersonic cruise vehicles was evaluated. A wind-tunnel model was developed which integrates realistic vehicle components with two waverider shapes ...

Effect of surfactants on liquid side mass transfer coefficients: a new insight [PDF]

open access: yes, 2009
Specific experiments are proposed to investigate the effect of surfactants on liquid side mass transfer coefficients. They are based on the determination of the liquid side mass transfer coefficient kL at a free gas-liquid interface, under controlled ...

Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

open access: yesAdvanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
