Harmonic Phasor Measurements in Real-World PMU-Based Acquisitions
Mario Paolone, Asja Derviskadic, Guglielmo Frigo
Modern distribution networks prove to be easily prone to power quality issues, and in particular to the presence of harmonic. components in the voltage and current signals, due to the increasing presence of nonlinear loads, distributed generation, and rene ...
IEEE2019Reduced Leakage Synchrophasor Estimation: Hilbert Transform Plus Interpolated DFT
Mario Paolone, Asja Derviskadic, Guglielmo Frigo
Synchrophasor estimation is typically performed by means of spectral analysis based on the discrete Fourier transform (DFT). Traditional DFT approaches, though, suffer from several uncertainty contributions due to the stationarity assumption, spectral leak ...
2018On Short Sums Of Trace Functions
Philippe Michel, Chandra Sekhar Raju
We consider sums of oscillating functions on intervals in cyclic groups of size close to the square root of the size of the group. We first prove non-trivial estimates for intervals of length slightly larger than this square root (bridging the "Polya-Vinog ...

Nikola Besic, Urs Martin Germann, Daniele Nerini
In this paper we present a non-stationary stochastic generator for radar rainfall fields based on the short-space Fourier transform (SSFT). The statistical properties of rainfall fields often exhibit significant spatial heterogeneity due to variability in ...
Copernicus GmbH2017Enantioselective Copper-Catalyzed Oxy-Alkynylation of Diazo Compounds
Jérôme Waser, Durga Prasada Rao Hari
Enantioselective catalytic methods allowing the addition of both a nucleophile and an electrophile onto diazo compounds give a fast access into important building blocks. Herein, we report the highly enantioselective oxyalkynylation of diazo compounds usin ...
2017An Improved Approach for the Calculation of the Transient Ground Resistance Matrix of Multiconductor Lines
The general integral expressions for the elements of the ground impedance matrix do not have an analytical inverse transform in the time domain. Therefore, the ground transient resistance of a multiconductor line is commonly evaluated in the time domain by ...
Ieee-Inst Electrical Electronics Engineers Inc2016DFT-based synchrophasor estimation processes for Phasor Measurement Units applications: algorithms definition and performance analysis
Among the various logical components of a phasor measurement unit (PMU), the synchrophasor estimation (SE) algorithm definitely represents the core one. Its choice is driven by two main factors: its accuracy in steady state and dynamic conditions as well a ...
The Institution of Engineering and Technology - IET2015On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas
Irène Antoinette Philipoussis, Toralf Scharf, Joab Di Francesco, Maurine Malak Karam Awadallah
We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...
Spie-Soc Photo-Optical Instrumentation Engineers2014Empirical Study of Noise Dependence in Electrochemical Sensors
Giovanni De Micheli, Sandro Carrara, Seyedeh Sara Ghoreishizadeh
We report the experimental study of noise in electrochemical biosensors as related to voltage and concentration. A comparison with experiments is performed for H2O2 and Ferrocyanide with bare sensors and with sensors functionalized wi ...
2013Computing exact Fourier series coefficients of IC rectilinear polygons from low-resolution fast Fourier coefficients
We present a novel, accurate and fast algorithm to obtain Fourier series coecients from an IC layer whose description consists of rectilinear polygons on a plane, and how to implement it using o-the-shelf hardware components. Based on properties of Fourier ...
