Polyethylene Sheeting as a Water Surface Cover in Sub-zero Temperatures [PDF]

open access: yes, 1973
The occurrence of temperatures below -20°C in central Alaska produces a situation conducive to the formation of ice fog. By far the largest source of ice fog in the Fairbanks area is the evaporation of water in the cooling ponds of power plants.

Numerical modelling of hailstone impact on the leading edge of a wind turbine blade [PDF]

open access: yes, 2013
The scale of modern blades means that tip speeds in excess of 100ms-1 are now common in utility scale turbines. Coupling this with a hailstone terminal velocity ranging from 9ms-1 to 40ms-1, the relative impact velocity becomes highly significant.

Gaussian Process Supported Stochastic MPC for Distribution Grids

open access: yesIEEE Open Journal of Control Systems
The efficacy of control systems for distribution grids can be influenced by different sources of uncertainty. Stochastic Model Predictive Control (SMPC) can be employed to compensate for such uncertainties by integrating their probability distribution ...
