Computing New Optimized Routes for GPS Navigators Using Evolutionary Algorithms

GPS navigators are now present in most vehicles and smartphones. The usual goal of these navigators is to take the user in less time or distance to a destination. However, the global use of navigators in a given city could lead to traffic jams as they have a highly biased preference for some streets. From a general point of view, spreading the traffic throughout the city could be a way of preventing jams and making a better use of public resources. We propose a way of calculating alternative routes to be assigned by these devices in order to foster a better use of the streets. Our experimentation involves maps from OpenStreetMap, real road traffic, and the microsimulator SUMO. We contribute to reducing travel times, greenhouse gas emissions, and fuel consumption. To analyze the sociological aspect of any innovation, we analyze the penetration (acceptance) rate which shows that our proposal is competitive even when just 10% of the drivers are using it.Spanish MINECO project TIN2014-57341-R (http://moveon.lcc.uma.es).

Respuestas antiguas y contemporáneas ante el anuncio de catástrofes : Píndaro, el Peán 9 ante el eclipse de sol y los pronósticos del cambio climático

El presente artículo investiga algunas respuestas de la sociedad ante el pronóstico de calamidades comunitarias, estableciendo una comparación entre la respuesta de una comunidad antigua y algunas respuestas de la sociedad globalizada del siglo XXI ante los pronósticos científicos concernientes al cambio climático. En el campo disciplinar de la filología, se propone una lectura más compleja del Peán 9 de Píndaro (fr. 52k Maehler = A1 Rutherford), que busca dar cuenta del fenómeno del eclipse de sol, descrito por el poeta como un signo de catástrofes comunitarias, en el marco de los posibles conocimientos astronómicos de la época, y en la red de significados implícita en las formas de pensamiento simbólico propias de la Grecia arcaica. Tanto las actitudes antiguas como las actuales ante el anuncio de calamidades comunitarias se consideran desde una perspectiva antropológica apoyada en la investigación moderna sobre mitología.This paper presents an investigation about some answers given by societies in front of the announcements of communal calamities, proceeding by a comparison between the answer of an archaic community and some attitudes of the global society of our time in front of the scientific diagnostics concerning the climatic change. In the field of Classical scholarship, this article proposes a more complex interpretation of Pindar’s 9th Paian (fr. 52k Maehler = A1 Rutherford), that seeks to understand the phaenomenon of the solar eclipse, described by the poet as a sign of communal catastrophes, in the background of the possible astronomical knowledge of Pindar’s time and in the net of meanings proper to the symbolic thought of Archaic Greece. Both ancient and actual attitudes towards the announcements of communal calamities are measured with an anthropological perspective based on modern investigation about mythology.Fil: Torres, Daniel Alejandro

Red Swarm: Smart Mobility in Cities with EAs

This work presents an original approach to regulate traffic by using an on-line system controlled by an EA. Our proposal uses computational spots with WiFi connectivity located at traffic lights (the Red Swarm), which are used to suggest alternative individual routes to vehicles. An evolutionary algorithm is also proposed in order to find a configuration for the Red Swarm spots which reduces the travel time of the vehicles and also prevents traffic jams. We solve real scenarios in the city of Malaga (Spain), thus enriching the OpenStreetMap info by adding traffic lights, sensors, routes and vehicle flows. The result is then imported into the SUMO traffic simulator to be used as a method for calculating the fitness of solutions. Our results are competitive compared to the common solutions from experts in terms of travel and stop time, and also with respect to other similar proposals but with the added value of solving a real, big instance.Ministerio de Economía y Competitividad y FEDER (TIN2011-28194

BANANA IV: Two aligned stellar rotation axes in the young eccentric binary system EP Crucis: primordial orientation and tidal alignment

With observations of the EP Cru system, we continue our series of measurements of spin-orbit angles in eclipsing binary star systems, the BANANA project (Binaries Are Not Always Neatly Aligned). We find a close alignment between the sky projections of the rotational and orbital angular momentum vectors for both stars (beta_p = -1.8+-1.6 deg and |beta_s|<17 deg). We also derive precise absolute dimensions and stellar ages for this system. The EP Cru and DI Her systems provide an interesting comparison: they have similar stellar types and orbital properties, but DI Her is younger and has major spin-orbit misalignments, raising the question of whether EP Cru also had a large misalignment at an earlier phase of evolution. We show that tidal dissipation is an unlikely explanation for the good alignment observed today, because realignment happens on the same timescale as spin-orbit synchronization, and the stars in EP Cru are far from syncrhonization (they are spinning 9 times too quickly). Therefore it seems that some binaries form with aligned axes, while other superficially similar binaries are formed with misaligned axes.Comment: ApJ accepted, 10 pages, 7 figure
