Pero Tafur and Bertradon de la Broquière in Constantinople: The Ceremonial Image of Mary of Trabzond and the Diplomatic Meetings around the Council o…
2019
After the fall of Constantinople (1453), Pero Tafur and Bertrandon de La Broquière make known their works, which are two of the most important travel books written in Europe during the fifteenth century. Both travellers had known, between fifteen and twenty years before, the emperor of Greece, John VIII Palaiologos, Pope Eugene IV and other protagonists of the councils of Basel (1431-1434) and Ferrara-Florence (1438-1439), which decreed the union between the Roman and Greek churches. The travellers were, thus, witnesses, but also informants and active diplomats for the attempts of religious and political union, which Pope Pius II tried to revive after the fall of Constantinople. Tafur and L…
La consagración de los derechos fundamentales: de principios generales a texto fundacional de la Unión Europea
2014
<p>El autor argumenta que el reconocimiento formal de los derechos fundamentales como parte de los fundamentos comunes de la UE mediante la remisión a la Carta de los Derechos Fundamentales en el Tratado de Lisboa (otorgándole carácter vinculante y, por ende, elevando su rango y confiriéndole el mismo valor jurídico que los Tratados) ha proporcionado una mayor apariencia constitucional a la UE, pero no un nivel más generoso de protección y de disfrute de la ciudadanía. En efecto, además de haber prescindido de garantías específicas, la Carta de la UE ha introducido diversas asimetrías inaceptables, tales como la quiebra del principio de indivisibilidad (los derechos civiles y los soci…

Phenomena in the Cyber World
2015
This chapter describes and evaluates the cyber world, including its phenomena, from a strategic perspective. As no universally accepted definitions for the cyber world exist, associated literature and publications address it in many different ways. A five-layer model is constructed for cyber threats, which include cybervandalism, cybercrime, cyber intelligence, cyberterrorism and cyberwarfare. This chapter depicts the standards-based risk model, cyber operations and cyberweaponry, as well as the critical structures of society as the targets. Moreover, cyber security definitions are provided. Cyber world phenomena are addressed in more detail in other chapters of this book.
Adaptive control of a seven mode truncation of the Kolmogorov flow with drag
2009
Abstract We study a seven dimensional nonlinear dynamical system obtained by a truncation of the Navier–Stokes equations for a two dimensional incompressible fluid with the addition of a linear term modelling the drag friction. We show the bifurcation sequence leading from laminar steady states to chaotic solutions with increasing Reynolds number. Finally, we design an adaptive control which drives the state of the system to the equilibrium point representing the stationary solution.
High Reynolds number Navier-Stokes solutions and boundary layer separation induced by a rectilinear vortex
2013
Abstract We compute the solutions of Prandtl’s and Navier–Stokes equations for the two dimensional flow induced by a rectilinear vortex interacting with a boundary in the half plane. For this initial datum Prandtl’s equation develops, in a finite time, a separation singularity. We investigate the different stages of unsteady separation for Navier–Stokes solution at different Reynolds numbers Re = 103–105, and we show the presence of a large-scale interaction between the viscous boundary layer and the inviscid outer flow. We also see a subsequent stage, characterized by the presence of a small-scale interaction, which is visible only for moderate-high Re numbers Re = 104–105. We also investi…
The Positive Relationship between Moderate-to-Vigorous Physical Activity and Bone Mineral Content Is Not Mediated by Free Leptin Index in Prepubertal…
2021
Purpose: Moderate-to-vigorous physical activity (MVPA) positively influences bone mineral content (BMC) in prepubertal children, but it is unknown whether this relationship is partially mediated by free leptin index. The aim of this study was to examine whether the relationship between MVPA and total body less head (TBLH) BMC is mediated or moderated by free leptin index in prepubertal children. Methods: We performed a cross-sectional analysis on 401 children (194 girls) from baseline examinations of the Physical Activity and Nutrition in Childhood Study. We applied the four-way decomposition mediation analysis method to assess whether free leptin index, measured from fasted blood samples, …
Damage identification by a modified Ant Colony Optimization for not well spaced frequency systems
2011
Recently, it has been shown , that a damage detection strategy based on a proper functional calculated on the analytical signal of the structural dynamical response, consents to identify very low damage level. In this regard, they stressed the efficiency of Hilbert Transform to obtain the analytical response representation that shows more sensitivity for predicting damage with respect to the simple signal response. Then, a damage identification procedure based on the minimization of the difference between theoretical and measured data was proposed with satisfactory results. Unfortunately, this procedure, since the need of use of band pass filter around the natural frequency of the system, f…
Ai confini dell’etica: la Teoria dell’amore e del libero arbitrio
2021
Dai suoi studi dedicati alla Divina Commedia (vol. XIX/2), Romano Guardini ci propone un’analisi dell’etica dantesca, vale a dire dell’architettura di valori che Dante pose a reggere i regni dell’aldilà, e che dall’aldilà disvela il corretto ordine dell’universo e l’essenza propria della persona. A condizione dell’agire etico v’è il valore della libertà, l’umana facoltà di scelta che in vita incontra il vincolo della responsabilità: la persona libera è responsabile poiché e finché nella vita terrena decide di sé. Il senso della “Teoria dell’amore e del libero arbitrio” che Guardini scorge come nucleo dell’etica dantesca è quello di una libertà che attratta dal valore -e dai valori- ad essi …
