Sons, Brothers and Relatives in the Entourages of the Roman Provincial Commanders during the Republic: A Characteristic Behaviour of the Roman Ruling Class
Durante la época de la República era una costumbre bien conocida que el cónsul o pretor destinado a una provincia se dotara de una serie de colaboradores y acompañantes que constituÃan la cohors o comitiva del imperator. Dicha comitiva solÃa componerse de personas vinculadas a los cÃrculos sociales y particularmente familiares del mandatario en cuestión, siendo habitual encontrar en éstas a parientes, hermanos e incluso hijos de los mandos romanos. Aunque los autores clásicos no suelen conceder demasiada atención el papel que cumplÃan los hijos y parientes en el séquito de colaboradores de un mandatario provincial, su presencia habitual en estas comitivas indica que se trataba de un comportamiento caracterÃstico y representativo de la clase polÃtica romana, cuyo interés no se hallaba sólo en contribuir a la promoción polÃtica y social de los implicados, sino en el hecho en sà de participar de unos hábitos distintivos y privativos de la nobilitas.Universidad de Málaga.

The probability of non-confluent systems
We show how to provide a structure of probability space to the set of
execution traces on a non-confluent abstract rewrite system, by defining a
variant of a Lebesgue measure on the space of traces. Then, we show how to use
this probability space to transform a non-deterministic calculus into a
probabilistic one. We use as example Lambda+, a recently introduced calculus
defined through type isomorphisms.Comment: In Proceedings DCM 2013, arXiv:1403.768
Proof Normalisation in a Logic Identifying Isomorphic Propositions
We define a fragment of propositional logic where isomorphic propositions,
such as and , or and
are identified. We define System I, a
proof language for this logic, and prove its normalisation and consistency
Path planning and map monitoring for self-driving vehicles based on HD maps
Este trabajo ha sido realizado dentro del contexto del proyecto Techs4AgeCar en el grupo de investigación
Robesafe, cuyo objetivo es el desarrollo de un vehÃculo de conducción autónoma. Forma parte de
dos lÃneas distintas del proyecto, la de mapeado y la de planificación, ya que ambas están directamente
relacionadas.
Se ha desarrollado un planificador de rutas global basado en mapas de alta defición (HD Maps) offline
previamente generados.
Por otro lado, también se ha cubierto toda la parte de generación de mapas que posteriormente son
utilizados por el planificador.
Además, se ha desarrollado un módulo capaz de aprovechar la información proporcionado por el mapa,
de forma que se monitorizan los elementos relevantes y cercanos al coche que afectan a la ruta, como son
carriles, intersecciones y elementos regulatoriosThis work has been done within the context of the Techs4AgeCar project in the Robesafe research
group, whose project focuses on the development of an autonomous driving vehicle. This work is part of
two different layers of the project, mapping and planning layers, since both are directly related.
A global route planner has been developed based on previously generated offline HD Maps.
Therefore, the entire part of generating maps that are later used by the planner has also been covered.
In addition, a module capable of taking advantage of the information provided by the map has
been developed, so that the relevant elements close to the vehicle that affect the route such as lanes,
intersections and regulatory elements are monitored.Máster Universitario en IngenierÃa Industrial (M 141
The Vectorial -Calculus
We describe a type system for the linear-algebraic -calculus. The
type system accounts for the linear-algebraic aspects of this extension of
-calculus: it is able to statically describe the linear combinations
of terms that will be obtained when reducing the programs. This gives rise to
an original type theory where types, in the same way as terms, can be
superposed into linear combinations. We prove that the resulting typed
-calculus is strongly normalising and features weak subject reduction.
Finally, we show how to naturally encode matrices and vectors in this typed
calculus.Comment: Long and corrected version of arXiv:1012.4032 (EPTCS 88:1-15), to

Event-Driven Monte Carlo: exact dynamics at all time-scales for discrete-variable models
We present an algorithm for the simulation of the exact real-time dynamics of
classical many-body systems with discrete energy levels. In the same spirit of
kinetic Monte Carlo methods, a stochastic solution of the master equation is
found, with no need to define any other phase-space construction. However,
unlike existing methods, the present algorithm does not assume any particular
statistical distribution to perform moves or to advance the time, and thus is a
unique tool for the numerical exploration of fast and ultra-fast dynamical
regimes. By decomposing the problem in a set of two-level subsystems, we find a
natural variable step size, that is well defined from the normalization
condition of the transition probabilities between the levels. We successfully
test the algorithm with known exact solutions for non-equilibrium dynamics and
equilibrium thermodynamical properties of Ising-spin models in one and two
dimensions, and compare to standard implementations of kinetic Monte Carlo
methods. The present algorithm is directly applicable to the study of the real
time dynamics of a large class of classical markovian chains, and particularly
to short-time situations where the exact evolution is relevant
