Analysing the Impact of Frequency Bands on Partial Discharge Measurement Outcomes in Generators Through Model‐Based Approach

open access: yesHigh Voltage, EarlyView.
ABSTRACT The electromagnetic wave produced by a partial discharge (PD) covers a broad range of frequencies, from a few kHz to several 100 MHz. Because of the nonlinear response of the stator winding, each frequency component of the PD pulse experiences different levels of attenuation as it travels through the winding structure. Consequently, the choice

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...
