An empirically grounded agent based simulator for the air traffic management in the SESAR scenario

2017

In this paper we present a simulator allowing to perform policy experiments relative to the air traffic management. Different SESAR solutions can be implemented in the model to see the reaction of the different stakeholders as well as other relevant metrics (delay, safety, etc). The model describes both the strategic phase associated to the planning of the flight trajectories and the tactical modifications occurring in the en-route phase. An implementation of the model is available as an open-source software and is freely accessible by any user. More specifically, different procedures related to business trajectories and free-routing are tested and we illustrate the capabilities of the mode…

Scaling laws of strategic behavior and size heterogeneity in agent dynamics

2008

The dynamics of many socioeconomic systems is determined by the decision making process of agents. The decision process depends on agent's characteristics, such as preferences, risk aversion, behavioral biases, etc.. In addition, in some systems the size of agents can be highly heterogeneous leading to very different impacts of agents on the system dynamics. The large size of some agents poses challenging problems to agents who want to control their impact, either by forcing the system in a given direction or by hiding their intentionality. Here we consider the financial market as a model system, and we study empirically how agents strategically adjust the properties of large orders in orde…

Making Telescopes and Partying with the Stars: Amateur Astronomy in Spain during Franco’s Dictatorship

2016

Franco’s dictatorship was characterized by an official narrative that criminalized the liberal tradition of previous periods. Such a discourse defined an ideologically correct science that censured the subordination of Spanish science to foreign influence and sought to create a new scientific tradition. However, recent studies have revised these aims and suggest that there was a continuity of scientific and technological programmes and practices before and after the Spanish Civil War. This paper contributes to these investigations with further evidence, focusing on several practices that characterized the development of amateur astronomy during this period. Special attention is paid to the…

Goodness-of-fit tests in many dimensions

2004

A method is presented to construct goodness-of-fit statistics in many dimensions for which the distribution of all possible test results in the limit of an infinite number of data becomes Gaussian if also the number of dimensions becomes infinite. Furthermore, an explicit example is presented, for which this distribution as good as only depends on the expectation value and the variance of the statistic for any dimension larger than one.

BEF Analogy for Concrete Box Girder Analysis of Bridges

2010

<p>Box girder, due to its high torsional stiffness, is very appropriate for railway and highway long- medium span bridges. This type of cross section, subjected to transversely non-uniform loads, present warping and distortion phenomena. Accurate but time-consuming numerical procedures are available for determination of further strains and stresses caused by cross-section deformation. In this paper warping and distortion of box girders is evaluated through BEF analogy, by writing a 4th order differential equation. The problem is solved for practical cases of box girders by considering internal diaphragms stiffness. Graphs are supplied to designers and main design parameters affecting …

Current distribution of Pilularia globulifera L. in Poland – changes of geographical range and habitat preferences

2013

<em>Pilularia globulifera </em>is a subatlantic European fern threatened with extinction. In Poland, it reaches the eastern border of its continuous range. Up to the end of the 20th century, it was observed here in 21 stands; only 2 of them existed by the second half of the century, so the species was categorized as critically endangered. Five new locations have been found in western and northwestern Poland during the last 10 years. Abundant and permanent populations grow in 3 locations, while 2 stands were ephemeral. All the current stands are situated in anthropogenic habitats with spontaneous vegetation, in oligotrophic to eutrophic waters. One of the new localities is about …

The Real World in a Geographical Imagery: World of Warcraft as Playful Cartography?

2017

World of Warcraft (WoW) is an extremely well-known and wide-spread virtual universe, populated by millions of people living, as of 2014, in 244 different countries, and so coming from different cultures. The game can be considered the final result of a half-century of growing interest in fantasy and virtual worlds; starting from Tolkien’s The Lord of the Rings. In the passage from book to videogame, fantasy has become an immersive experience that captures the player and forces him or her to revise their idea of how the world works. Everyone can read these worlds as simple games or, rather, through multifarious levels that show the connections between reality and virtuality. Our paper aims a…

Persecution and Patronage: Oscar Buneman’s years in Britain

2016

The German student Oscar Bunemann, in trouble with the Nazi authorities in the mid-1930s, chose to emigrate to Britain and pursue a PhD there. After emigration, his surname appears as Buneman. On the verge of completing his degree in 1940, he was detained as an enemy alien and spent almost a year in internment. Upon release, he found work as an atomic scientist in England, and went on to lead a post-war career as a pioneering plasma physicist in the USA.We study forced migration of European scientists before and during the Second World War, and scientific patronage in the host countries. Buneman’s case is interesting from several points of view. Being a non-Jewish, non-communist, anti-Nazi …
