Distributed $n$-player approachability and consensus in coalitional games

2015

We study a distributed allocation process where, at each time, every player: i) proposes a new bid based on the average utilities produced up to that time, ii) adjusts such allocations based on the inputs received from its neighbors, and iii) generates and allocates new utilities. The average allocations evolve according to a doubly (over time and space) averaging algorithm. We study conditions under which the average allocations reach consensus to any point within a predefined target set even in the presence of adversarial disturbances. Motivations arise in the context of coalitional games with transferable utilities (TU) where the target set is any set of allocations that makes the grand …

Game Theory with Engineering Applications

2016

Engineering systems are highly distributed collective systems—decisions, information, and objectives are distributed throughout—that have humans in the loop, and thus decisions may be influenced by socioeconomic factors. Engineering systems emphasize the potential of control and games beyond traditional applications. Game theory can be used to design incentives to obtain socially desirable behaviors on the part of the players, for example, a change in the consumption patterns on the part of the “prosumers” (producers-consumers) or better redistribution of traffic. This unique book addresses the foundations of game theory, with an emphasis on the physical intuition behind the concepts, an an…

Nuevos factores de riesgo para la progresión del Glaucoma

2015

INTRODUCCIÓN El Glaucoma es una neuropatía óptica de desarrollo progresivo que afecta a 90 millones de habitantes del planeta, siendo la forma clínica conocida como glaucoma primario de ángulo abierto (GPAA) la primera causa de ceguera irreversible en los países desarrollados. Los factores de riesgo para su desarrollo incluyen en primer lugar la presión intraocular, pero también la edad, la raza, la predisposición familiar, el espesor corneal central, miopía y presión de perfusión ocular han sido descritos como importantes en el desarrollo y/o progresión del glaucoma, entre otros. No obstante, hay evidencia acerca de la existencia de otros factores de riesgo, los denominados emergentes, así…

Disponibilidad de productos y servicios en línea en el mercado único digital

2021

En el sector del comercio electrónico de la UE, los consumidores han visto en multitud de ocasiones obstaculizadas las transacciones en línea cuando intentaban adquirir el producto o contratar el servicio de un comerciante situado en otro Estado miembro debido a la técnica del bloqueo geográfico. Conocedor de ello, el legislador vela por la represión de las prácticas discriminatorias en las transacciones comerciales en la UE; esto es, por que no se den situaciones en las que no exista una justificación objetiva para el trato diferente por razón de la nacionalidad, de la residencia o del lugar de establecimiento (incluidos criterios indirectos como la dirección IP o los datos de pago) del cl…

Geometric and morphologic evolution of normal fault planes and traces from 2D to 4D data

2003

Abstract The detailed 3D geometry of normal fault planes is described and analysed using datasets from outcrop studies (2D), seismic surveys (3D) and analogue models (4D). Different geometric configurations of simple isolated normal faults are studied by reference to processes of normal fault propagation. When a normal fault propagates without interacting with other fault zones, the entire border of the principal plane displays characteristic connected secondary structures. These secondary structures cause bifurcations of the principal fault terminations. The along-strike terminations of the principal plane display typical bifurcation configurations (‘ear geometry‘). The orientation of the …

Vasellame in vetro dalle cisterne del castello di Butera

2012

The assemblage of glass artefacts, which is the subject of this contribution, has been retrieved from four cisterns (A, B, C, F) of the Medieval Castle of Butera. They are closed contexts, which were not manipulated by modern interventions, and permit a better defnition of the chronology of the glass objects through their association with ceramic material

Influenze tra processo ed esiti: alleanza, coesione e cambiamento in un gruppo terapeutico a lungo termine

2012

Questo lavoro esplora, in un gruppo terapeutico con pazienti gravi, due tra le variabili di processo più indagate nelle terapie di gruppo, l’alleanza terapeutica e la coesione, analizzandone le associazioni con gli esiti del trattamento in termini di sintomi e difese. E’ stato esaminato un gruppo a lungo termine, semi-aperto, a cadenza settimanale. L’osservazione si è svolta per un periodo di 18 mesi, per un totale di 50 sedute. Sono stati monitorati 11 soggetti che riportavano diverse diagnosi nell’Asse I e II del DSM IV. TR Gli strumenti di esito usati sono stati l’SCL-90: Symptom Check List; l’ OQ-45: Outcome Question-naire 45.2; e il DSQ: Defense Style Questionnaire. Mentre per rilevare…
