Surrogate modelling for ice accretion prediction on wind turbine blades based on support vector regression

open access: yesIET Renewable Power Generation, EarlyView.
Proposing a solution to the threat of ice accretion on wind turbine blades in extreme cold weather, this study introduces surrogate modelling using support vector regression for accurate prediction. The surrogate model, rigorously evaluated for reliability, demonstrates that real‐time pitch angle adjustments, informed by both the model and ...

Cs4Ca[Si8O19]: a new mixed tetrahedral–octahedral oxosilicate, its topological features and comparison with other interrupted framework silicates

open access: yesActa Crystallographica Section B, EarlyView.
The crystal structure of the mixed tetrahedral–octahedral framework silicate Cs4Ca[Si8O19] has been solved. A topological analysis of the present compound and other interrupted framework silicates is presented.Single crystals of a previously unknown caesium calcium silicate with the composition Ca4Ca[Si8O19] have been obtained during a systematic study

The Effect of Land Fragmentation on Risk and Technical Efficiency of Austrian Crop Farms

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Using a 2007–2014 panel of Austrian crop farms, we analyse the effect of multiple dimensions of land fragmentation on farms' production efficiency and risk performance. We use data envelopment analysis (DEA), a non‐parametric linear programming approach, to estimate efficiencies.

Dude, everyone wants pattern analysis tools (DEWPAT): Tools for measuring visual pattern complexity from digital images

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Understanding the diversity and function of complex colour patterns is a fundamental interest in ecology and evolutionary biology, but progress on many questions is limited by our ability to quantify diverse visual patterns. We address this problem by introducing Dude, Everyone Wants Pattern Analysis Tools (DEWPAT), a Python package for ...
