Validation of a Probabilistic Mathematical Model for Soybean Seed Separation in a Gravity Column

Сельскохозяйственные машины и технологии
In mathematical models of the separation process in a gravity column, the coefficient of bar vibration is frequently disregarded as seeds and impurities move along the curved surface of the gravity column, which, in turn, affects the quality of ...

Performance of tuned liquid column dampers considering maximum liquid motion in seismic vibration control of structures

, 2012
The optimum design of tuned liquid column damper (TLCD) is usually performed by minimizing the maximum response of structure subjected to stochastic earthquake load without imposing any restrictions on the possible maximum oscillation of the liquid ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Vibrations of the reed and the air column in the bassoon

Journal of the Acoustical Society of Japan (E), 1989
Reed vibrations and pressure variations in the reed have been observed at the same time for the lowest note of a bassoon artificially blown. For comparison, the observations have been performed also for a cone simulating the bassoon and for a bassoon without tone holes. Behaviors of the bassoon and the bassoon-like systems artificially blown are fairly
