Forcing boundary-layer transition on an inverted airfoil in ground effect and at varying incidence [PDF]
, 2016 Presented at 34th AIAA Applied Aerodynamics ConferenceThe influence of the laminar boundary-layer state on a wing operating in ground effect at Re = 6 × 10 has been investigated using experiments with a model that provides two-dimensional flow and ...

Evaluation of Four Reanalysis Datasets against Radiosonde over Southwest Asia
Atmosphere, 2020 Upper-air observational networks in Southwest Asia (SWA) are geographically sparse and reanalysis datasets (RDs) are a typical alternative. However, RDs can perform with varying degrees of quality and accuracy due to differences in assimilation schemes ...

Impedance‐Matched High‐Overtone Thickness‐Shear Bulk Acoustic Resonators With Scalable Mode Volume
Advanced Science, EarlyView.A bottom‐electrode‐free high‐overtone bulk acoustic resonator is achieved by lateral excitation of antisymmetric thickness‐shear modes on a lithium‐niobate‐on‐silicon platform. Planar electrode geometry eliminates conventional loading along the resonance path and confines acoustic energy within the electrode gap.

Caltech and aeronautics: a presentation by the California Institute of Technology [PDF]
, 1958 The outstanding accomplishment of Caltech in the field of aeronautics is not that it has taught, but that it has always had something new to teach. When most aircraft were glued together from bamboo, balsawood, and canvas, Caltech was teaching the next ...

Theoretical analysis of perching and hovering maneuvers [PDF]
, 2013 Unsteady aerodynamic phenomena are encountered in a large number of modern aerospace and non-aerospace applications. Leading edge vortices (LEVs) are of particular interest because of their large impact on the forces and performance.

Advanced Science, EarlyView.Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Application of quasi-homogeneous anisotropic laminates in grid-stiffened panel design [PDF]
, 2012 Composite laminates are derived for standard configurations with quasi-homogeneous anisotropic properties, whereby in-plane and out-of-plane stiffness properties are concomitant.
