We report about a hierarchical design for extracting ship features and recognizing ships from SAR images, and which will eventually feed a multisensor data fusion system for airborne surveillance. The target is segmented from the image background using directional thresholding and region merging processes. Ship end-points are then identified through a ship centerline detection performed with a ...

This paper introduces a Monte-Carlo algorithm for online planning in large POMDPs. The algorithm combines a Monte-Carlo update of the agent’s belief state with a Monte-Carlo tree search from the current belief state. The new algorithm, POMCP, has two important properties. First, MonteCarlo sampling is used to break the curse of dimensionality both during belief state updates and during planning...

We consider the problem of belief tracking in a planning setting where states are valuations over a set of variables that are partially observable, and beliefs stand for the sets of states that are possible. While the problem is intractable in the worst case, it has been recently shown that in deterministic conformant and contingent problems, belief tracking is exponential in a width parameter ...

Este artículo analiza y compara cuatro obras narrativas de la literatura española del siglo xxi –el relato «Un recorrido por los monumentos La aventura», recogido en El hacedor (de Borges). Remake (2011) Agustín Fernández Mallo, las novelas Marienbad eléctrico (2015) Enrique Vila-Matas, Feliz final (2018) Isaac Rosa (2020) Bruno Galindo– a partir un motivo argumental común todas ellas: visita n...

We describe the outcome and experience of trying to develop an architecture and framework for a Networked Object Oriented Gaming Architecture (NOOGA). The aim of this project was to create an easily extensible framework that facilitates teaching students about object oriented design, design patterns, and software engineering in an interesting context. Our original goal was to develop a game ser...

After Pearl Harbor1 I1 asked whether an American Catalina Pilot had really found the Bismarck. I was informed that he was Ensign L.B. Smith, U.S. Navy, stationed with 209 Squadron, R.A.F. Coastal Command at Lough Erne. He sighted the Bismarck 550 miles west of Land’s End. Two other U.S. Navy Ensign pilots of R.A.F. Catalinas took over shadowing the Bismarck on 26 May 19412,3. Much later I learn...
