We present a simple and practical distributed routing algorithm based on backward learning. The algorithm periodically oods scout packets that explore paths to a destination in reverse. Scout packets are small and of xed size; therefore, they lend themselves to hop-by-hop piggy-backing on data packets, largely defraying their cost to the network. The correctness of the proposed algorithm is ana...

In this paper, we present TV Scout, a recommendation system providing users with personalized TV schedules. The TV Scout architecture addresses the “cold-start” problem of information filtering systems, i.e. that filtering systems have to gather information about the user’s interests before they can compute personalized recommendations. Traditionally, gathering this information involves upfront...

This document describes the specifications of the demonstrations to be performed in the project. 1/ Reconfigurable RF TX chain The proposed RF TX demonstrator hardware is based on commercially available components but at the same time it is near to the solution obtained during the analysis of the RF part of Scout terminal. 2/ Link adaptation on hardware validator The document provides the speci...

Nous rapportons un cas de reprise évolutive méningiome agressif ostéolytique, à développement intra et extra-crânien chez un patient de 37 ans qui présente depuis 10 ans une volumineuse voussure de la région pariéto-occipitale. Le patient a bénéficié en 2010 d'une exérèse partielle d'un processus expansif intracrânien qui s'est révélé être un méningiome méningothélial à l'anatomopathologie. Le ...

In wireless sensor networks, sensor nodes are extremely power constrained, so energy efficient clustering mechanism is mainly considered in the network topology management. A new clustering mechanism based on the polymorphic ant colony (PAC) is designed for dynamically controlling the networks clustering structure. According to different functions, the nodes of the networks are respectively def...

This paper presents a novel method for localizing miniature mobile robots (Scouts) using dynamic contours. An observer robot with a camera follows the miniature robot as it moves and jumps in the workspace. Dynamic contours are very effective in tracking the fast accelerations and decelerations of the Scout robot. We show initial experimental results with particular emphasis on the task of moni...

Introduction Automated scan plane planning is expected to provide consistent scan plane prescriptions and to improve MRI scanner usability. Consistent scan planes are useful for follow-up examinations. The typical workflow of a scan plane setup requires careful manual positioning, and it suffers from inter-operator variability. Furthermore, having to perform a scan plane setup for each examinat...

In this paper, we propose a hybrid Pareto-based artificial bee colony (HABC) algorithm for solving the multi-objective flexible job shop scheduling problem. In the hybrid algorithm, each food sources is represented by two vectors, i.e., the machine assignment vector and the operation scheduling vector. The artificial bee is divided into three groups, namely, employed bees, onlookers, and scouts...
