Coupled experiment/simulation approach for the design of radiation-hardened rare-earth doped optical fibers and amplifiers [PDF]

, 2011
We developed an approach to design radiation-hardened rare earth -doped fibers and amplifiers. This methodology combines testing experiments on these devices with particle swarm optimization (PSO) calculations.

Diurnal and Seasonal Variations of Photosynthetic Energy Conversion Efficiency of Field Grown Wheat

Frontiers in Plant Science, 2022
Improving canopy photosynthetic light use efficiency and energy conversion efficiency (εc) is a major option to increase crop yield potential. However, so far, the diurnal and seasonal variations of canopy light use efficiency (LUE) and εc are largely ...

Radiation interception and radiation use efficiency in mixtures of winter cover crops

Field Crops Research, 2021
Abstract Context Cover crops are sown in autumn after harvest of a main crop to capture residual nitrogen and to build biomass that will contribute to soil organic matter after being ploughed under. Mixtures are purportedly more productive than pure stands of single species.

Radiation use efficiency increases when the diffuse component of incident radiation is enhanced under shade [PDF]

, 1998
Theoretical analyses have shown the radiation use efficiency of maize, soybean, and peanut to increase with a decrease in the level of incident radiation and an increase in the proportion of diffuse radiation. This study compared the growth and radiation

Efficient sound radiation using a bandgap structure [PDF]

Applied Physics Letters, 2019
This work reports on the use of bandgaps to increase the efficiency of sound radiation employing defect modes on a phononic crystal (PnC). A PnC consisting of a 2D array of studs on an aluminum plate is considered, and a defect is created by removing four studs.

Modelling radiation interception and radiation use efficiency for sugar beet under variable climatic stress

, 2001
European sugar beet crops suffer drought stress, and climate change is likely to increase the frequency and severity of drought. Changes in rainfall pattern may also affect the radiation environment.
