Nonlinear dual-frequency modulation QEPAS using a single laser for resolving overlapping spectral features

Conventional single-frequency wavelength modulation spectroscopy faces inherent limitations in multi-component gas sensing, due to restricted detection dimensionality and unavoidable trade-offs in modulation parameters. To overcome these issues, we propose a Quartz-Enhanced Photoacoustic Spectroscopy sensing technique based on single-laser dual-frequency superimposed modulation. By simultaneously injecting two independent high-frequency modulation signals, matching the fundamental and overton...

Italia Resurgens Lusitanis Fratribus Anhelat Corde Urban Policies and the “Shared Latinity” in Marcello Piacentini’s Projects for the City of Porto

This contribution aims to explore the cultural and architectural dynamics between Italy and Portugal during the 1930s and 1940s, focusing on the significance of the cultural exchanges between the two countries in promoting a sense of “shared Latinity” and in diffusing the Italian language and architectural culture within the Lusitanian context. A series of initiatives such as the journal “Italian Studies in Portugal” and university courses offered by the ...

Augmented Bolza-Based Optimal Control Approach for Frequency Regulation and Power Tracking in Islanded Microgrids

The variability of renewable energy sources (RESs) and load demand variations may lead to power alternations in converter control actions, potentially compromising stability and reliability and posing operational security risks, particularly in islanded microgrids. To address these challenges, this research introduces an innovative optimal control approach structured around a reformulated version of the Bolza problem. A variational control methodology is employed to ensure regularity, with bo...
