Abstract:
In this thesis, we systematically examine the ECN (Explicit Congestion Notification) mechanism to be applied to some AQM (Active Queue Management) techniques developed in recent years, namely, RED (Random Early Detection), BLUE, ARED (Adaptive RED) and PI-RED (Proportional and Integral RED). We use packet marking as the indication of network congestion, instead of the strategy of dropping packet currently adopted by these AQM algorithms. The performance comparison of ECN-AQM with AQM has been conducted in not only a single bottleneck network but also a multi-bottleneck network environment. The

Abstract:
A deadlock avoidance algorithm for a centralized resource allocation system is presented. Unlike the Banker's algorithm, this proposed algorithm makes use of the state of the previous safe sequence to construct a new safe sequence. The performance of this proposed algorithm is compared to that of both the Banker's algorithm and an efficient algorithm proposed by Belik. The simulation results show that our algorithm's execution time is significantly better than the Banker's algorithm and is very competitive with Belik's algorithm. In addition, our Modified Banker's Algorithm produces optimal re

This thesis represents a relatively new aspect of computing with regard to robotics. The need for fast, efficient collision avoidance algorithms is growing rapidly. Because conventional methods are complex and require vast amounts of computation, heuristic algorithms are more appealing. The focus of this thesis is the problem of moving a point through three dimensional space while avoiding known polyhedral obstacles. A heuristic algorithm to find shortest (near-optimal) collision-free paths in the presence of polyhedral obstacles, given initial and final positions, is presented. Previous metho

The problem of aircraft conflict detection and resolution (CDR) in uncertainty is addressed in this thesis. The main goal in CDR is to provide safety for the aircraft while minimizing their fuel consumption and flight delays. In reality, a high degree of uncertainty can exist in certain aircraft-aircraft encounters especially in cases where aircraft do not have the capabilities to communicate with each other. Through the use of a probabilistic approach and a multiple model (MM) trajectory information processing framework, this uncertainty can be effectively handled. For conflict detection, a r

Kinematic algorithms within CASs evaluate sensor input and apply assumptions describing human-response timing and deceleration to determine when an alert should be presented. This dissertation presents an analytic assessment of dynamic function and performance CASs and associated driver performance for preventing automotive rear-end crashes. A method for using naturalistic data in the evaluation of CAS algorithms is described and applied to three algorithms. Time-series

Abstract:
Les manipulateurs industriels collaboratifs ouvrent une nouvelle ère dans la fabrication flexible, où les robots et les humains sont capables de coexister et de travailler ensemble. Cependant, divers défis persistent pour parvenir à une collaboration complète entre les robots et les humains en milieu industriel. Dans cette thèse, deux défis principaux - la sécurité et la collaboration - sont abordés pour atteindre cet objectif. Concernant la sécurité, la thèse présente une méthode d'évitement des collisions en temps réel qui permet au robot d'ajuster les chemins générés hors ligne pour une tâc

Abstract:
In this paper, the architecture and implementation of an embedded controller for a steering based semi-autonomous collision avoidance system on a 1/10th scale model is presented. In addition, the development of a 2D hardware-in-the-loop simulator with vehicle dynamics based on the bicycle model is described. The semi-autonomous collision avoidance software is fully contained onboard a single-board computer running embedded GNU/Linux. To eliminate any wired tethers that limit the system’s abilities, the driver operates the vehicle at a user-control-station through a wireless Bluetooth interface

Abstract:
Cette thèse de doctorat s'inscrit dans le cadre des activités de recherche sur les systèmes de lancement aéroporté autonome. L'originalité du travail est basée sur la planification de mission effectuée par un algorithme de type A*(A-étoile). Cet algorithme a été amélioré pour répondre aux besoins de la mission de largage d'un lanceur. Il effectue la planification du chemin le plus court dans un espace tridimensionnel. Le meilleur chemin est choisi à partir de plusieurs points de passage générés dans la région de mission. Une région peut être une phase du vol ou une partie du profil de vol. Le

Abstract:
Le projet de thèse vise à contrôler et coordonner les actions d’un ensemble de drones autonomes, pour un fonctionnement en essaim. Trois applications clefs sont ciblées : — un problème d’inventaire d’entrepôts combinant un ensemble de robots terrestres et de drones, — un problème de mesure de la qualité de l’air (caractérisation de panaches de polluants), — un problème de déploiement de drones pour de multiples missions de surveillance sur de longues durées. Ces applications ajoutent aux difficultés liées à la robotique mobile collective un volet d’optimisation sous incertitude, la conception

Abstract:
Dans ce travail, nous nous intéressons au problème de reconstruction de phase de signaux à valeurs réelles en dimension finie, un défi rencontré dans de nombreuses disciplines scientifiques et d’ingénierie. Nous explorons deux approches complémentaires : la reconstruction avec et sans régularisation. Dans les deux cas, notre travail se concentre sur la relaxation de l’hypothèse de Lipschitz-continuité généralement requise par les algorithmes de descente du premier ordre, et qui n’est pas valide pour la reconstruction de phase lorsqu’il formulée comme un problème de minimisation.
