Intermodulation electrostatic force microscopy for imaging surface photo-voltage

, 2014
We demonstrate an alternative to Kelvin Probe Force Microscopy for imaging surface potential. The open-loop, single-pass technique applies a low-frequency AC voltage to the atomic force microscopy tip while driving the cantilever near its resonance ...

Impact of Virtual Synchronous Generators on Frequency-Constrained Unit Commitment: A Neural Network-Assisted Framework for Assessing Rate of Change of Frequency

IEEE Access
The increasing penetration of inverter-based resources (IBRs) into electric power systems and the retirement of synchronous generators (SGs) both reduce system inertia and challenge frequency stability.

Experimental Validation of a Diesel Genset Frequency Dynamics Model for Use in Remote Area Power Systems

IEEE Access
Diesel generators (gensets) are often the lowest-cost electric generation for reliable supply in remote microgrids. The development of converter-dominated diesel-backed microgrids requires accurate dynamic modeling to ensure power quality and system ...

Space-time domain solutions of the wave equation by a non-singular boundary integral method and Fourier transform

, 2017
The general space-time evolution of the scattering of an incident acoustic plane wave pulse by an arbitrary configuration of targets is treated by employing a recently developed non-singular boundary integral method to solve the Helmholtz equation in the
