3D unsteady flow in oscillating compressor cascade [PDF]
An experimental and computational study has been carried out to enhance current understanding of three dimensional (3D) cascade aeroelastic mechanisms. 3D unsteady pressure data produced during executing this project is the first-of-its-kind, which can ...

This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

Relics, writing, and devotion in early medieval Chelles
The discovery in 1983 of a collection of relics with their medieval identificatory tags in the parish church of Chelles opened new avenues for research on devotional and writing practices in this Frankish royal foundation. This is the first systematic study of the corpus of relic labels that accompanied these sacred objects, particularly of the subset ...

A full three-dimensional lifting surface theory based on the double linearization concept is developed for a rotating annular cascade model operating at axial supersonic velocity. It is assumed that each blade vibrates with infinitesimal displacement amplitude under small mean loading.

ABSTRACT Parkinson's disease (PD) is most often diagnosed in late middle age and old age (mid to late 60s), leaving younger people with PD facing uncertainties and the long‐term challenge of life with a neurodegenerative illness. To advance understanding of the psychosocial burden associated with PD for younger people, we explored PD disclosure ...

Multi-scale freeform surface texture filtering using a mesh relaxation scheme [PDF]
Surface filtering algorithms using Fourier, Gaussian, wavelets, etc, are well-established for simple Euclidean geometries. However, these filtration techniques cannot be applied to today's complex freeform surfaces, which have non-Euclidean geometries ...

Dual‐Tasking Exacerbates Force and Neural Control Unsteadiness in Older Adults With Sarcopenia
ABSTRACT Background Sarcopenia is associated with impaired physical function. Dual‐task conditions, which increase cognitive demand during motor performance, may reveal deficits in neuromuscular control that are not evident during isolated motor tasks.

ILLIAC 4 and lifting surface theory with boundary layer [PDF]
Aerodynamic flutter and a re-written computer program for its study are discussed. Data cover: (1) lifting surface theory with boundary layer, (2) incompressible, two dimensional, unsteady flow with control surfaces, (3) improved unsteady theory, (4 ...

Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

An asymptotic unsteady lifting-line theory with energetics and optimum motion of thrust-producing lifting surfaces [PDF]
A low frequency unsteady lifting-line theory is developed for a harmonically oscillating wing of large aspect ratio. The wing is assumed to be chordwise rigid but completely flexible in the span direction.
