Using electric vehicle fleet as responsive demand for power system frequency support [PDF]

open access: yes, 2013
Based on conventional car driving patterns, it has been recognized that typically a car remains stationary for 95% of the time, only being driven on the road for the remaining 5% of that time on average.

Fast Frequency Support Through LED Street Lighting in Small Non-Synchronous Power Systems

open access: yesIEEE transactions on industry applications, 2023
Small-sized non-synchronous islands, which are inherently characterized by low system inertia, will face in the next years the challenge of integrating larger and larger amount of renewable energy sources, leading to further reduction of inertia. Several

Detection of Cochlear Hearing Loss Applying Wavelet Packets and Support Vector Machines [PDF]

open access: yes, 2004
The aim of this paper is to evaluate the application of the wavelet packet transform (WP) and support vector machines (SVM) to transient evoked otoacoustic emissions (TEOAE) in order to achieve a detection of frequency-specific hearing loss. We introduce
