Improved equivalent optical turbulence method for anisotropic compressible and atmospheric turbulence under different beam transmission distances

open access: yesScientific Reports
The impact of different turbulence on beams can be seen as optical distortions caused by refractive index fluctuations around vortices in turbulence. Therefore, from the perspective of transmission effects, the transmission outcomes of beam in different ...

Thickness variation parameter in a thin rotating disc by finite deformation [PDF]

open access: yesFME Transactions, 2013
Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Normalisation of shear test data for rate-independent compressible fabrics [PDF]

open access: yes, 2007
This article describes a method of using both picture frame (PF) and bias extension (BE) tests together to characterize accurately the trellis shearing resistance of engineering fabrics under low in-plane tension conditions.

A Compressible Formulation of the One-Fluid Model for Two-Phase Flows

open access: yesFluids
In this paper, we introduce a compressible formulation for dealing with 2D/3D compressible interfacial flows. It integrates a monolithic solver to achieve robust velocity–pressure coupling, ensuring precision and stability across diverse fluid flow ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Effect of Mach number on the structure of turbulent spots [PDF]

open access: yes, 2006
Direct numerical simulations have been performed to study the dynamics of isolated turbulent spots in compressible isothermal-wall boundary layers. Results of a bypass transition scenario at Mach 2, 4 and 6 are presented.

Animal models of hemorrhage, parameters, and development of hemostatic methods

open access: yesLaboratory Animal Research
Hemorrhage is a prevalent side effect of various injuries and can be life-threatening in certain instances. It is categorized into compressible and non-compressible types, each necessitating distinct modeling, laboratory assessments, and hemostatic ...
