Flexibility of grid interactive water heaters: The situation in the US
2023
Among different solutions to increase flexibility of electricity system, grid interactive water heaters (GIWHs) can make a large contribution, against a relatively low cost. They can advantageously be used within a single building, a local energy community or within an entire distribution grid, thanks to the very fast response time, low cost, highly distributed resource and widely demonstrated technology. In the near future, the flexibility potential of GIWHs will certainly increase, thanks to the advantageous flexibility programs that have been implementing in some area of the world, with the aim of coordinating several million of GIWHs with the electricity network. In this study, we asses…
Grid-forming converters. A critical review of pilot projects and demonstrators
2022
Grid-forming control can be a useful solution for all dynamic issues in weak grids and for providing ancillary services. It represents the new frontier in modern power electronics, responding to the needs of power systems more and more rich in renewables and, for this reason, with lower inertia. Today, the research on grid-forming is mainly oriented to propose new and more effective control schemes and to evaluate their performances with simulation tools, but few works in the literature focus on the results of on-field experimentation. Therefore, this paper aims to provide a comprehensive review of grid-forming pilot projects and demonstrators developed worldwide. The work describes the mai…
A visual framework to support collaborative coding activities
2019
In this paper, we present a framework named SIRENE, a Web-based visual programming environment, where teachers and students can collaboratively interact, using a flexible and versatile definition of visual programming code instead of pre-established rules. After the description of the architecture of the SIRENE framework, the preliminary results of a pilot trial with secondary school students will be presented; these results will lead to the final remarks and directions for further developments.
IL MUTAMENTO DELLA CORTE EUROPEA DEI DIRITTI DELL’UOMO IN SENSO COSTITUZIONALE ATTRAVERSO L’ANALISI DELLE SENTENZE PILOTA: UNA QUESTIONE DI LEGITTIMI…
Lo studio si propone di analizzare, in primo luogo, la prassi giurisprudenziale della procedura di sentenza pilota, inaugurata dai giudici della Corte EDU per porre rimedio al problema del sovraccarico dei ricorsi, in grado di mettere a rischio il funzionamento del sistema sovranazionale di tutela dei diritti fondamentali: vengono messi in evidenza, dunque, i tratti distintivi, i presupposti e le finalità dello strumento giudiziario, facendo ampio ricorso alla dottrina di riferimento. In secondo luogo, l’analisi della procedura delle sentenze pilota si inquadra nella più ampia questione della progressiva evoluzione verso una giurisdizione di carattere costituzionale: con particolare riferi…
LA TRADUZIONE DEI FUMETTI: PILOTE IN iTALIA
2018
La rivista di fumetti italiana Pilot che ebbe breve vita nel corso degli anni Ottanta del secolo scorso è direttamente emanazione dell’omonino periodico francese Pilot che ha attraversato, influenzandola, trent’anni della fumettistica d’oltralpe. In questo articolo si prenderanno in considerazione le motivazioni e gli esiti delle trasposizione dei fumetti francesi contenuti in questa famosa rivista in italiano.
Analysis of sterols by high-performance liquid chromatography/mass spectrometry combined with chemometrics
2006
A newly developed high-performance liquid chromatography/mass spectrometry (HPLC/MS) method has been successfully used to analyze plasma concentrations of various phytosterols (cholestanol and beta-sitosterol) and cholesterol metabolites (desmosterol and lathosterol). This was based on an unusual solvent combination of water/methanol vs. methanol/acetone/n-hexane applied on a Purospher Star RP-18e (125 x 2 mm, 3 microm) column, which proved excellent for the separation, identification and quantification of plasma sterols. Simple solid-phase extraction preparation of plasma samples was performed, followed by the developed fast and robust HPLC separation. Results on four groups of people were…

Neck and Shoulder Muscle Activation Among Experienced and Inexperienced Pilots in +Gz Exposure
2017
Background The aim of the present study was to compare differences in electromyography (EMG) activation of the neck and shoulder muscles between groups of inexperienced and experienced pilots during controlled +Gz exposure in a centrifuge. Methods The subjects were volunteer cadets (inexperienced group) and lieutenants (experienced group) undergoing their first centrifuge training. The first group did not have any high performance aircraft (HPA) experience, while the latter one had a 1-yr experience of intense flying of HPA. During the centrifuge run, EMG activity was recorded from the left and right shoulder, neck flexor, and neck extensor muscles. Results The pilots without HPA experience…
