Human alterations to aquatic ecosystems are leading to decreases in species richness and biomass and subsequent changes in community composition. In many cases species losses are non-random: species with traits poorly adapted to the new environmental conditions suffer greater losses. We used long-term data from a southern US river, the Kiamichi River, to evaluate the synergistic effects of regi...

The thermally coupled incompressible inductionless magnetohydrodynamics (MHD) problem models the flow of an electrically charged fluid under the influence of an external electromagnetic field with thermal coupling. This system of partial differential equations is strongly coupled and highly nonlinear for real cases of interest. Therefore, fully implicit time integration schemes are very desirab...

The wall-matching methodology of Wilcox is modified to include a solid-wall, thermal-conduction model. This coupled fluid-thermal-structure model is derived assuming that the wall thermal-structure behavior is locally one-dimensional and that structural deformations, due to thermally induced stresses, are not significant. The one-dimensional coupled fluid-thermal-structure model is derived such...

We study the phenomenon of synchronization in pairs doubly clamped, mechanically coupled silicon micro-oscillators. A continuous-wave laser beam is used to drive micro-beams into limit cycle oscillations and detect using interferometry. Devices different dimensions are introduce frequency detuning, short bridges connecting as mechanical coupling between oscillators. The region plotted for MEMS ...

We analyse the potential of solar hydrogen production in remote and cold world regions such as Antarctica quantify efficiency benefits thermal coupling.
