Nanostructured Ni Based Anode and Cathode for Alkaline Water Electrolyzers
2019
Owing to the progressive abandoning of the fossil fuels and the increase of atmospheric CO2 concentration, the use of renewable energies is strongly encouraged. The hydrogen economy provides a very interesting scenario. In fact, hydrogen is a valuable energy carrier and can act as a storage medium as well to balance the discontinuity of the renewable sources. In order to exploit the potential of hydrogen it must be made available in adequate quantities and at an affordable price. Both goals can be potentially achieved through the electrochemical water splitting, which is an environmentally friendly process as well as the electrons and water are the only reagents. However, these devices stil…
Three-mode pneumatic management of marine U-tank systems
2012
Abstract This paper deals with a new pneumatic control strategy for the roll damping enhancement of marine U-tank stabilizers. The proposed technique consists in a three-mode operation, where the control is active only within a limited resonant range around the ship natural frequency, whereas the control valves are kept closed in the remaining frequency range. Moreover the connection valve between the two air chambers is either closed or partially opened for the low or high frequencies, respectively. The pressurized air for the active control is fed by a turbo-blower set aboard and operates accelerating the motion of the water mass in the U-duct. The theoretical analysis is conducted in the…
The Construction of Collective Memory: from Franco to Democracy
2004
Collective memory is neither spontaneous nor random, but the result of a series of selective practices. It establishes group identity and sets power relations between groups. The author considers the process of selection through a case study of the transformation of Franco’s regime in Spain into a democracy. Collective memory of the time is shown to be organized around an event (the Munich Coalition or contubernio) and around the democratic transition. The author traces two opposing notions, negationist (denying any importance to Munich) and the pro-democratic, and concludes that the memory of the transition is only the memory of those who won the civil war, who were also those who enginee…
Il paesaggio urbano come strategia di comunicazione
2014
Convegno Nazionale A.I.D.T.P.G.
El diálogo entre la Corte Interamericana de Derechos Humanos, los Tribunales Constitucionales de la Región Andina y el Tribunal Europeo de Derechos H…
2015
La comunicación entre tribunales, posibilita la existencia de un intercambio de ideas sobre lo que se debe entender por el contenido de un derecho o de una garantía, con la tendencia de otorgarse mayor protección a favor del ser humano; diálogo que no implica la existencia del predominio de una jurisdicción (internacional o estatal) sobre otra, al contrario con las interrelaciones que se producen entre tribunales, lo que se busca es lograr convergencias interpretativas que propicien un entendimiento común de los derechos y de las garantías. Se ha elegido para trabajar algunas garantías y derechos, como son el plazo razonable, juez natural, libertad de pensamiento-expresión e información- e …
Hacia la convergencia de las estadísticas de las finanzas públicas y la contabilidad pública en Europa a nivel central y local
2018
[EN] The main aim of this paper is to study the convergence between micro and macro systems of government accounting information, looking to contribute to the analysis of accounting harmonization process in the EU, as a tool to improve the comparability of financial, budgetary, and aggregated statistical reports, in order to improve social, political and economic decision-making and accountability. All this is obviously located in the current context of the EU, with a high degree of harmonization of accounting standards between the International Public Sector Accounting Standards (IPSAS), and those applied for the preparation of national accounts, ruled by European System of National and Re…
An efficient proposal for the application of simulated annealing algorithms
2014
Complex nonlinear optimization problems require specific resolution techniques. These problems are often characterized by a solution space that presents many local optima. In these cases, local search algorithms, as the classical descent neighborhood search method, have a heavy drawback: the optimization algorithm generally converges towards a local minimum. To avoid getting trapped in a local minimum, the optimization algorithm must allow to accept worse solutions than the current one. Several kinds of algorithms have been ideated for this purpose and they differ for the acceptance criteria of a pejorative solution. Among such algorithms it is possible to remember the Taboo Search (TS) and…
¿Cómo aprender a trabajar en equipos integrados? El papel del aprendizaje cooperativo en la formación de directivos
2009
En la literatura de dirección estratégica, la investigación que explica los resultados de los equipos enfatiza el papel de los procesos y, concretamente, del comportamiento integrador. Por otro lado, en educación superior el trabajo en equipo es una herramienta aceptada y en extensión pero con usos heterogéneos y resultados dispares. El objetivo de este trabajo es demostrar que el aprendizaje cooperativo, como parte integral del proceso de aprendizaje, permite adquirir un mejor nivel de comportamiento integrador a los miembros del equipo. Analizando el comportamiento integrador en 101 estudiantes que utilizaron aprendizaje cooperativo y comparándolos con 120 de un grupo de control demostram…
Le attività di culto nella scuola pubblica, tra laicità, «libertas Ecclesiae» e libertà religiosa collettiva
2016
Il contributo, sottoposto a valutazione, è frutto della riflessione comune dei due Autori; tuttavia, i paragrafi 1, 2, 3 e 4 sono opera di Fabiano Di Prima, i paragrafi 5, 6, e 7 di Marco Dell’Oglio SOMMARIO: - 1. Premessa. Il "ritorno" della religione e la riaffermazione degli Stati nazionali nell'ultimo quarto di secolo; l'"accerchiamento" della laïcité - 2. Il mancato sviluppo di una metodica giurisprudenziale focalizzante la "specificità" della laicità italiana; l'emersione di un trend individuante solo i (relativi) profili comuni alla laïcité - 3. Un caso paradigmatico: la sentenza n. 166 del 2016 del T.A.R. Emilia Romagna sul tema dello svolgimento di attività cultuali nella scuola pu…
