Voltage source inverters: An easy approach for fast fault detection
2013
Fault-tolerant converters have been widely investigated for years and nowadays an extensive technical literature on this field exists. This paper presents a novel fault detection algorithm based on a simple geometrical approach. In the algorithm analysis both the case of faults in single device and the loss of an entire inverter leg have been considered. The proposed methodology is characterized by simplicity, low computational and implementation effort with a consequent fast execution and easy control integration. The suggested algorithm is verified by means of experimental tests and reveals a valid and suitable alternative to the existing state of the art in the field of inverter fault de…
Reliability Analysis of Three Homogeneous Fault-tolerant Inverter Topologies
2016
Abstract—In this article, non-redundant fault-tolerant inverter topologies are addressed. A novel fault-tolerant control strategy which enhances performances during post-fault operation is proposed. Benefits from the proposed strategy over conventional fault-tolerant topologies are investigated in terms of system reliability. Cost, post-fault performances, and system reliability of the proposed solution are compared with both a conventional triac-based fault-tolerant inverter and a T-type inverter. The reliability analysis of each selected configuration is carried out by means of Markov chains. The analysis is validated through a comparison of reliability and sensitivity curves. As shown by…
Agujero Transverso Bipartito en población rural del siglo XVII y en poblablación actual
2015
INTRODUCCIÓN La columna cervical se diferencia claramente de la región torácica y lumbar, tanto en su anatomía como en su biomecánica (Kapandji IA, 2007). Asimismo, la región cervical debe conciliar su gran movilidad con su papel clave en el paso de estructuras vasculares y nerviosas relacionadas con la región craneal (Gray H, 1989; Das, S et al, 2005; Drake RL et al, 2010; White TD et al, 2011). En este sentido, entre los rasgos anatómicos distintivos de las vértebras cervicales, se encuentra un orificio en las apófisis transversas, denominado foramen transverso, a través del cual asciende la arteria vertebral (White TD et al, 2011; Moore KL et al, 2013). Con respecto a los diámetros anter…

Il cammino indicato dalla Corte costituzionale per la disciplina del suicidio medicalmente assistito fra giurisprudenza di merito e perdurante attesa…
2021
The study aims to investigate the indicator path from the sentence of the Constitutional Court n. 242/2019 on medically assisted suicide. Pending the approval of the legislative discipline, on which Parliament is currently working, deemed necessary by the Constitutional Court itself to give certainty to such an ethically delicate matter, judges are increasingly finding themselves deciding on cases of medically assisted suicide and on the both on the level of criminal law and on the level of civil law, interpreting the constitutional jurisprudence on the subject in a constitutionally compliant
Energy Management and Smart Grids
2013
The paper outlines energy management concepts and the smart grid evolution. The necessity of considering energy management as a crucial innovation in load supplying to permit a more powerful penetration of renewable energy usage at the building and city level and to perform energy savings and CO2 emissions reduction is pointed out. The driving factors to enhance the current power distribution are presented, and the benefits concerning smart grids are underlined. In the paper, a specific energy management analysis is reported by considering all the electric value chain, and the demand-side management and distributed on site control actions are described. To verify the benefit of energy manag…
Anomalous electrical parameters improvement in Ruthenium DSSC
2018
. In this work, we present a series of measurements carried out on Ruthenium-based Dye Sensitized Solar Cells (DSSCs) after the application of different external electrical field values. Such measurements have been performed both in the dark and by illuminating the sample with sunlight emitted by a solar simulator (AM1.5G spectrum with a power irradiance of 1000 W/m2). Our results demonstrate that the initial electrical bias field modifies in both cases the behavior of the cell in terms of an anomalous improvement of the main electrical parameters.
Fyysisen aktiivisuuden yhteys muistitoimintojen muutoksiin 75-85-vuotiailla jyväskyläläisillä
2012
Fyysisen aktiivisuuden ja muistitoimintojen säilyminen ovat yhteydessä iäkkään ihmisen itsenäiseen suoriutumiseen päivittäisissä toiminnoissa ja aktiivisena yhteiskunnan jäsenenä toimimiseen. Tutkimuksen tarkoituksena oli selvittää, onko iäkkään henkilön itse ilmoittaman fyysisen aktiivisuuden määrällä ja määrässä kymmenen seuruuvuoden aikana tapahtuneella muutoksella yhteyttä muistia mittavien testien tuloksiin ja tuloksissa tapahtuneisiin muutoksiin, sekä onko yhteys samanlaista miehillä ja naisilla tai tutkimuksen eri vaiheisiin osallistuneilla.
