Total Frequency Spread: A New Metric to Assess the Switching Frequency Spread of FCS-MPC

Energies, 2022
This work proposes a metric to assess the spread of the switching frequency profile of power converters, focusing on Finite Control Set-Model-Predictive-Control (FCS-MPC)-based converters, and analyses the effect of the filter sizing, sampling period ...

Sets, heads and spreading in LFG

Journal of Language Modelling, 2018
Lexical Functional Grammar (LFG) uses abstract syntactic representation (f-structures) that tend to provide less hierarchical structure for certain constructions than those employed in other formal frameworks. This produces some good results, such as a very straightforward account of feature-sharing between phrases and their heads, but also certain ...

Modelling the spread of Wolbachia in spatially heterogeneous environments [PDF]

, 2012
The endosymbiont Wolbachia infects a large number of insect species and is capable of rapid spread when introduced into a novel host population. The bacteria spread by manipulating their hosts' reproduction, and their dynamics are influenced by the ...
