Gap Filling of Biophysical Parameter Time Series with Multi-Output Gaussian Processes

2018

In this work we evaluate multi-output (MO) Gaussian Process (GP) models based on the linear model of coregionalization (LMC) for estimation of biophysical parameter variables under a gap filling setup. In particular, we focus on LAI and fAPAR over rice areas. We show how this problem cannot be solved with standard single-output (SO) GP models, and how the proposed MO-GP models are able to successfully predict these variables even in high missing data regimes, by implicitly performing an across-domain information transfer.

Opening credits, sequences which accompany each episode of a television series, have radically changed over time. From being brief and marginal texts, edited with low care e watched with a low level of attention, they have become artistic and elegant sequences, often created by specialized companies to keep the viewer’s eyes glued to the screen. The opening credits still keep their original function – giving information about the programme – but nowadays they achieve their goal in various ways. The main titles refer to the content of the series using different tones, thereby setting a particular mood that prepares the viewer for the show. In this article, we will try to focus on these diffe…

Analisi statistica delle serie temporali di dati provenienti dalla rete di stazioni permanenti dell’UNIPA

2010

In questo lavoro ci si è proposti di verificare la qualità dei dati provenienti dalle stazioni permanenti appartenenti alla rete dell’Università di Palermo, creata nell’ambito del progetto PRIN2005 dal titolo: “Reti di stazioni permanenti GPS per il rilievo in tempo reale in impieghi di controllo e emergenza” e gestita dal Dipartimento di Rappresentazione. Attualmente sono disponibili serie temporali di soluzioni giornaliere. Queste permettono di individuare fenomeni ed eventi di varia natura come quella geofisica, geologica, metereologica e, proprio in virtù della numerosità di questi dati si possono rilevare fenomeni di rumore più o meno complessi che possono essere apparentemente di natu…

Itsemurhatartunnan taikauskosta: The Moth Diaries (2011) ja 13 Reasons Why (2017)

2018

Artikkeli käsittelee kahden itsemurhaa kuvaavan populaarikulttuurin tapausesimerkin, The Moth Diaries -elokuvan ja 13 Reasons Why -sarjan, ja tabun käsitteen välityksellä itsemurhaan liitettyä tartunnan pelkoa ja tämän pelon ilmenemistä viihteen ja median representaatioita säätelevässä Werther-efektissä. Keväällä 2017 julkaistun kohutun 13 Reasons Why -Netflix-sarjan ensimmäisen kauden vastaanotto ilmentää sosiologien, psykologien ja kansanterveystieteilijöiden tunnetuksi tekemää Werther-efektiä, median välittämäksi pelättyä itsemurhatartuntaa. Kanadalainen kauhudraama The Moth Diaries (2011) taas käsittelee sisällössään vanhemmalta lapselle periytyvää itsemurhatartuntaa vampyyrin hahmon vä…

Time domain symmetry parameters analysis for series arc fault detection

2022

This paper presents a feasibility study of exploiting the symmetry of some parameters for series arc fault detection in electrical circuits. The considered parameters are defined in the time domain and they are based on the current signal derivative and the evaluation of cross-correlation between subsequent observation windows. The analysis is carried out for AC systems, starting from an experimental characterization, which has been carried out in accordance with the Standard UL 1699 requirements for "unwanted tripping tests"and "operation inhibition tests"of arc fault circuit interrupters (AFCIs). The results obtained in different load conditions show that the proposed parameters can be us…

Performance Improvement of Grid-Integrated Doubly Fed Induction Generator under Asymmetrical and Symmetrical Faults

2023

The doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) suffers from voltage and frequency fluctuations due to the stochastic nature of wind speed as well as nonlinear loads. Moreover, the high penetration of wind energy into the power grid is a challenge for its smooth operation. Hence, symmetrical faults are most intense, inflicting the stator winding to low voltage, disturbing the low-voltage ride-through (LVRT) functionality of a DFIG. The vector control strategy with proportional–integral (PI) controllers was used to control rotor-side converter (RSC) and grid-side converter (GSC) parameters. During a symmetrical fault, however, a series grid-side converter…
