Bifurcation Scenarios in Electrostatic Vibration Energy Harvesters

O'Riordan, Eoghan ; Harte, Peter ; Blokhina, Elena ; Galayko, Dimitri ; Feely, Orla (IEEE, 2012-07)

In this paper, we present numerical bifurcation analysis of an electrostatic vibration energy harvester operating in constant-charge mode and using the in-plane gap closing transducer. We show how the system can be represented ...
A non-linear operator based method for harmonic feature extraction from speech signals

Kavanagh, Darren F. ; Boland, Frank (IEEE, 2007-11)

An important pre-processing stage in speech recognition systems is that of extracting phonetically pertinent acoustic features from the speech signal. These features form the basis for discriminative classification and ...
