Employing an orientation induction and rapid deposition strategy, the oriented growth of ZnO piezoelectric films is effectively regulated, resulting in significantly enhanced piezoelectric polarization and electromechanical response. The ZnO OIL sensor exhibits excellent sensitivity, fast response, and high measurement accuracy in practical ...

Optical measurement of unducted fan flutter [PDF]
A nonintrusive optical method is described for flutter vibrations in unducted fan or propeller rotors and provides detailed spectral results for two flutter modes of a scaled unducted fan. The measurements were obtained in a high-speed wind tunnel.

Abstract Background Ethics and diversity, equity, and inclusion (DEI) are critical aspects of engineering, and connections between ethics/DEI are becoming increasingly common place in engineering education and practice. For example, many engineering professional organizations have integrated DEI into their codes of ethics.

Extreme wildfire conditions shift coastal phytoplankton community structure in California
Abstract Extreme wildfires have increased in frequency and intensity globally, particularly in the Western United States. Here we examine how the 2020 Lightning Complex Fires in California influenced coastal phytoplankton communities using monitoring network data products in the Monterey Bay, the ocean region closest to this large fire.

System for indicating direction of intruder aircraft [PDF]
A pilot warning indicator system consisting of a flashing beacon, a detector, and an indicating panel is described. The detector responds to radiant energy from another aircraft's beacon by energizing particular signal lamps positioned in the periphery ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics
ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

Re-Computation of Numerical Results Contained in NACA Report No. 685 [PDF]
In an engineering note published in the Journal of Aircraft in the year 2000, Thomas A. Zeiler made generally known that some of the early works on aeroelastic flutter by Theodore Theodorsen and I.E. Garrick (NACA Report Nos. 496, 685, and 741) contained
