Comparison of analytical and wind-tunnel results for flutter and gust response of a transport wing with active controls [PDF]
Two flutter suppression control laws wre designed and tested on a low speed aeroelastic model of a DC-10 derivative wing. Both control laws demontrated increases in flutter speed in excess of 25 percent above the passive wing flutter speed.

Toward Energy Justice Principles for Sustainable Lithium‐Ion Battery Technologies
Advanced Energy and Sustainability Research, EarlyView.Prefeasibility life cycle assessment is used to evaluate the environmental, social, and supply chain impacts of lithium‐ion battery technologies, and the concept of distributional energy justice is discussed. By comparing chemistries and use cases, it reveals inequities in material sourcing and technology access.

Evaluation of four subcritical response methods for on-line prediction flutter onset in wind-tunnel tests [PDF]
The methods were evaluated for use in tests where the flutter model is excited solely by airstream turbulence. The methods were: randomdec, power-spectral-density, peak-hold, and cross-spectrum.

Agribusiness, EarlyView.ABSTRACT This study analyzes the effects of value co‐creation and creation of shared value in agricultural input marketing. This study used a sample of 178 agricultural companies in Costa Rica. The data were analyzed using partial least squares structural equation modeling (PLS‐SEM) with SMART PLS software. Our findings reveal the significant influence

Preliminary study of effects of winglets on wing flutter [PDF]
Some experimental flutter results are presented over a Mach number range from about 0.70 to 0.95 for a simple, swept, tapered, flat-plate wing model having a planform representative of subsonic transport airplanes and for the same wing model equipped ...
