Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]

open access: yes, 2012
We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

Multiple sets of solutions for harmonic elimination PWM bipolar waveforms: Analysis and experimental verification [PDF]

open access: yes, 2006
Multiple sets of solutions for the selective harmonic elimination pulse-width modulation method for inverter control exist. These sets present an independent solution to the same problem but further investigation reveals that certain sets may offer an ...

Multiple harmonic sources identification including inverter‐based distributed generations using empirical Fourier decomposition

open access: yesIET Generation, Transmission & Distribution, 2023
This paper proposes an intelligent approach based on the empirical Fourier decomposition (EFD) to identify harmonic sources at the point of common coupling (PCC) when different inverter‐based distributed generations (DGs) like microturbine (MT), battery ...

Impact of Multitemporal Land Use and Land Cover Change on Land Surface Temperature Due to Urbanization in Hefei City, China

open access: yesISPRS International Journal of Geo-Information, 2021
Land surface temperature (LST) is an essential parameter in the climate system whose dynamics indicate climate change. This study aimed to assess the impact of multitemporal land use and land cover (LULC) change on LST due to urbanization in Hefei City ...
