Power dispatching of active generators using droop control in grid connected micro-grid

2014

Masteroppgave i fornybar energi ENE 500 Universitetet i Agder 2014 Renewable energy promises a green energy future for the world. However, many technical problems still have to be solved. Almost all renewable energy sources require power electronic converters for power processing and therefore inverter control systems and power dispatching strategies are significant in renewable energy applications. The existing electricity grid architecture is based on centralized power generations while most renewable power generations are distributed and connected to lower or medium voltage networks. Some of important renewable energy resources such as solar and wind power are intermittent in nature. Thi…

Direct electricity production from Avgas UL91 fuel

2016

As fuel for fuel cells can be used various substances, but generally fuel cells are powered by hydrogen. However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. The paper presents the possibility of using Avgas fuel as fuel for fuel cell. The Avgas does not have the feature of electrical conductivity, for this reason a detergent (nonionic surfactant) was used for dissolving fuel in an electrolyte. The work shows possible electrooxidation of Avgas fuel emulsion prepared on the basis of a nonionic surfactant on a platinum electrode in an aqueous solution of H2SO4. As non-ionic surfactant was used the detergent Syntanol DS-10. The emulsion was …

Public-Interest Litigation before the ECtHR: Towards a Human Rights Approach to the “Universal” Protection of Cultural Heritage?

2022

Taking as a starting point the inadmissibility decision issued in 2019 by the European Court of Human Rights in the case Ahunbay and others v. Turkey, the article proposes some reflections concerning the possibility of lodging applications with the Court which are aimed at protecting collective interests and common goods as recognized (or emerging) under international law. While the case at hands concerned the specific issue of the protection of cultural heritage, it cannot be denied that, more generally, the importance in contemporary international law of public-interest litigation before international courts and tribunals is growing. And indeed, it is much discussed in the field of the pr…

L'interesse delle generazioni future in costituzione

2022

The work aims to analyse the prediction in the Constitution of the interest of future generations, to verify its impact in the political dimension and, consequently, the dynamics of the exercise of public power and administrative activity.

Fuzzy logic controller and game theory based distributed energy resources allocation

2020

Energy management and demand control through conventional energy generation sources are challenging for energy providers. Distributed energy resources (DERs) allocation near load centers may provide a suitable solution. The main contribution of the paper improves the voltage profile and reduce the active and reactive power losses in the distribution network. DERs are integrated with IEEE 33 bus system using fuzzy logic controller (FLC) and game theory for two different cases with unity and 0.9 power factor (PF) and compares with conventional methods of integration (i.e., modified novel method, power loss sensitivity method, voltage sensitivity analysis method). The capacity of DERs is optim…

From generation to degeneration. The health-disease link in Galen's corpus

2017

Through a reading of some significant passages a reconstruction is made of the main features of Galen’s rich reflection on the themes of health and disease, with particular attention to two aspects. On one side, there is an analysis of the limits within which disease is seen, in the Galenic corpus, as ‘degeneration’ in relation to a ‘natural’ state. On the other side, there is an investigation of whether, and to what extent, the physician from Pergamon accepts the idea, partly already present in Hippocrates, of the existence of diseases that, with a modern term, we would define as ‘genetic’. The marginality that this aspect seems to present – at least in theoretical works devoted to embryol…

La costruzione simbolica del conflitto generazionale nei discorsi politici di Renzi e Grillo

2018

L’età dei parlamentari italiani e dei principali leader politici è stata al centro delle ultime campagne elettorali nazionali ed europee. In entrambi gli schieramenti, dalla “rottamazione” di Matteo Renzi agli “zombie in poltrona” di Beppe Grillo, gli slogan incitavano a uno svecchiamento della classe politica italiana. Ma chi è il giovane e chi l’anziano al quale si riferiscono i due leader? Quali sono i ruoli che essi prospettano per giovani e anziani? Quali sono le soglie costruite nei discorsi pubblici e nei post sui siti web ufficiali e sui profili nei social network dei due leader? Quale dialettica si è sviluppata? Quali analogie e differenze rispetto alle rappresentazioni proposte da…

¿Cabe hablar de una «generación de la crisis»? Discusión en torno a una noción sobreexplotada

2018

This article states that nowadays there is an overuse (or a misuse) of the «Generation» idea. The discussion among many authors over the «Generation of crisis» concept suggests that it is useful to outline the characteristics of the target of population of the collective of youth who are mainly affected by the economic and social crisis over the past years. Nevertheless, through analyzing the meanings of the «Generation of Crisis» made by Mannheim, Ortega and other classic authors, it is clear that the social class approach together with the generational one are needed to define this concrete concept. The conclusion of the articleis that both approaches are seen as underpinning their utilit…

Body size at birth and age-related macular degeneration in old age

2019

Purpose To study associations between body size at birth and age-related macular degeneration (AMD) in old age. Methods The study sample consists of 1497 community-dwelling individuals (56.1% women) aged 67-89 years with birth data and retinal data collected twice in old age 5 years apart. Birth data (weight, length, birth order) were extracted from original birth records. Digital retinal photographs were graded to determine AMD status. Data on covariates were collected at the baseline physical examination in old age. Multivariable regression analyses were used to study the association between birth data and AMD adjusting for known confounding factors, including birth year cohort effects. R…
