Full textDenna rapport beskriver styrbeteenden för autonoma agenter och utvärderar hur användbar den tekniken är för att skapa flexibla agenter i kontinuerliga miljöer. Arbetet undersöker hur väl det går att använda styrbeteenden i en mer strikt kontrollerad miljö, nämligen biltrafik. De utvecklade agenterna agerar i en trafikmiljö där de navigerar för att följa en väg och undvika kollisioner med andra agenter. Agenterna använder en kombineringsarkitektur som gör det möjligt att använda olika beräkningsmodeller. Agenterna är testade i två scenarion där teknikens användbarhet och flexibilitet är studerad. Resultatet från utvärderingen visar att tekniken är väldigt flexibel men kan kräva mycket finjustering för att uppnå bästa resultat.

CAPES
A Política Comum de Segurança e Defesa (PCSD), instituída pelo Tratado de Lisboa em 2007, consolida a posição da União Europeia enquanto agente securitário nas relações internacionais do século XXI. Esta tese buscou confirmar esta hipótese através de robusto arcabouço teórico, fragmentado em três partes: a) uma extensa revisão da literatura sobre a integração europeia atrelada à narrativa do processo histórico da integração no continente europeu, expondo o caminho que levou à construção de uma política comum de segurança e defesa na UE; b) o exame do delineamento legalinstitucional da PCSD, iniciado com o estabelecimento da Política Externa e de Segurança Comum (PESC) pelo Tratado de Maastricht em 1992, até o desenvolvimento de um novo paradigma intervencionista; c) e, finalmente, o debate sobre identidade na UE e a construção de uma identidade própria à organização, em paralelo aos nacionalismos dos seus Estados-membros. A análise desenvolvida a partir de abordagens construtivistas de regimes internacionais e complexos regionais de segurança demonstra que a PCSD delimita a identidade europeia enquanto agente de segurança internacional ao estabelecer um novo paradigma intervencionista nas relações internacionais, calcado em uma combinação de instrumentos civis e militares baseados em uma reduzida quantidade de recursos cirurgicamente aplicados a objetivos estritamente delimitados, com vistas a garantir a eficácia e aumentar a eficiência das suas operações. Estes dois elementos – a identidade europeia e o novo paradigma intervencionista – confirmam que a União Europeia qualifica-se como um agente securitário internacional.

Full textThis dissertation presents a mechanism to incorporate planning autonomy in multiagent organizational models. Therefore, we propose a formal model to represent presence or absence of planning autonomy, using two types of objectives: procedural and declarative ones. The model is implemented using the JaCaMo platform, in which an organization case study is proposed, where agents who have or do not have planning autonomy co-exist.

Full textBaudoin Dafflon’s doctoral work is placed in the general frame of self-organised systems. This kind of systems bases on the hypothesis that their organizationcan be the result of the individual behaviour of each one of the autonomous and proactive component entities. This emergent organization satisfies the objectives entrusted to the self-organizing system. This thesis is mainly directed to application domains in which the self-organizing system is composed of intelligent, frequently mobile material devices places in a physical, uncertain environment. Case-studies made included in this Thesis belong to the vehicle platoon problem.This Thesis interests mainlyto the decision-making problem of the self organizing systems of this kind. This aspect is particularly important when the system evolves in an uncertain environment. Uncertainty can be the consequence of an imperfect knowledge of the environment or because of the occurrence of unpredictable events. In those situations the autonomous entities have to decide locally about the best action to be performed in order for the global organization to be maintained. Even if information exchange among autonomous entities is not excluded a-priori, this doctoral work has been done under the restriction of non-communication, in order to investigate the reach of completely de-centralised approaches.Among the contributions of this thesis we can mention the following. Firstly, the proposal of an architecture that separates decision making and control, thereby allowing a simpler integration of uncertainty-management. An example from the application domain (vehicle platoons) is obstacle avoidance. Secondly, this thesis introduces a hierarchy of multi-agent systems such that decision-making is also conceived as a self-organized process in a virtual agent’s world. The later is built from an abstraction process based on the perceptions produced by material agents. Lastly, this thesis proposes physics-inspired interaction mechanisms for virtual agents. Those interaction models based on phenomena such as attraction-repulsion forces or gas dynamics, allow for a computational decision making process based on the laws and properties of the adopted physical models.Doctoral work presented in this Thesis has been done in the framework of the ANR-VTT project

Full textThe behavioral simulation of virtual entities in dynamic and unknown environments becomes a complex problem. Deliberative agents cannot handle unforeseen situations. Reactive agents interact with the environment in real time, but they do not easily adapt their behaviors to dynamic environments. The research of this thesis focuses on mechanisms inspired from Artificial Life, offering characteristics of reactivity, adaptation and evolution. We propose an architecture mixing different mechanisms in order to increase the reasoning capacity of virtual entities. This behavioral architecture consists of two models. The first one allows the autonomous entities to act quickly on the environment. This model is based on the potential fields' method which has already proved its efficiency in navigation problems for autonomous entities. However, this solution is expensive because the designer has to define manually the potential fields' parameters for each environment. To solve this problem, we have developed an additional model allowing the autonomous entities to obtain adaptive behaviors in dynamic environments. The second model is an extension of the classifier system XCS, whose role is to evolve discrete actions corresponding to the potential fields' parameters. We have validated our behavioral architecture in a predator-prey problem. The performance of our architecture entirely depends on classifier systems. The possible actions remain discrete and predefined. .

Full textThe Internet of Things (IoT) aims to create a global ubiquitous ecosystem composed of large numbers of heterogeneous devices. To achieve this vision, the World Wide Web is emerging as a suitable candidate to interconnect IoT devices and services at the application layer into a Web of Things (WoT).However, the WoT is evolving towards large silos of things, and thus the vision of a global ubiquitous ecosystem is not fully achieved. Furthermore, even if the WoT facilitates mashing up heterogeneous IoT devices and services, existing approaches result in static IoT mashups that cannot adapt to dynamic environments and evolving user requirements. The latter emphasizes another well-recognized challenge in the IoT, that is enabling people to interact with a vast, evolving, and heterogeneous IoT.To address the above limitations, we propose an architecture for an open and self-governed IoT ecosystem composed of people and things situated and interacting in a global environment sustained by heterogeneous platforms. Our approach is to endow things with autonomy and apply the social network metaphor to createflexible networks of people and autonomous things. We base our approach on results from multi-agent and WoT research, and we call the envisioned IoT ecosystem the Social Web of Things.Our proposal emphasizes heterogeneity, discoverability and flexible interaction in the IoT. In the same time, it provides a low entry-barrier for developers and users via multiple layers of abstraction that enable them to effectively cope with the complexity of the overall ecosystem. We implement several application scenarios to demonstrate these features

This thesis explored aspects that can help balance the level of user control and system autonomy for intelligent privacy agents in the context of the Internet of Things. This proposed balance could be reached considering aspects related to wanting to be interrupted to have control and being able to be interrupted to exert this control. Through literature review of interruption and privacy literature, variables related to these two perspectives were identified. This led to the variable set "Intelligent Privacy Interruptions”. To verify and validate this set, two research actions were performed. The first one was an online survey that allowed us to perform a sanity check that these variables were acceptable in this work’s context. The second was an experience sampling user study with 21 participants that allowed us to better understand how user behavior is informed by these variables. Based on these two interventions it was possible to note that the selected variables seem to show relevance and that they can be used to inform the development and design of privacy agents. The limitations of the partial results notwithstanding, through a quantitative analysis of data collected form the user study and the qualitative analysis of the exit interviews, it was possible to note a common mental process between the participants of the user study when deciding whether to withhold or delegate decision control to the agent. Future studies should be performed to verify the possibility of expansion and creation of a behavior and preference model that can be integrated to the decisionmaking system of intelligent privacy agents.
Este trabalho investigou aspectos que podem ajudar a balancear o nível de controle de usuários e de autonomia de agentes inteligentes de privacidade no contexto da Internet das Coisas. Entende-se que esse balanceamento proposto poderia ser alcançado considerando aspectos relacionados a “querer” ser interrompido para ter controle e “poder” ser interrompido para exercer o controle. Por meio de revisão da literatura de interrupções e privacidade, variáveis relacionadas a esses dois aspectos foram identificadas, embasando a proposta de um conjunto de variáveis para “Interrupções de Privacidade Inteligentes”. Para verificar e validar esse conjunto de variáveis, duas ações de pesquisa foram feitas. A primeira foi um questionário online que serviu como uma verificação inicial de que as variáveis são adequadas ao novo contexto proposto por esse trabalho. A segunda foi um estudo de amostragem de experiência com 21 usuários para se entender melhor como essas variáveis podem vir a informar o comportamento de usuários. Os resultados obtidos sugerem que as variáveis selecionadas apresentam relevância e que podem ser usadas para informar o desenvolvimento e design de agentes de privacidade. Embora os resultados ainda sejam limitados, principalmente pela duração do estudo e grupo e número de usuários, através da análise quantitativa dos dados coletadas no estudo com usuários e da análise qualitativa das entrevistas realizadas pós-estudo notou-se um processo mental comum entre os usuários participantes do estudo para as tomadas de decisão de reter o controle ou delegá-lo ao agente. Estudos futuros devem ser realizados, procurando verificar a possibilidade de expandir o relacionamento das variáveis para a criação de um modelo de comportamento e preferência dos usuários que seja integrável ao sistema de decisão de agentes inteligentes de privacidade.

Full textThe purpose of this research is to study the relationship among motivational teaching styles (autonomy support vs. control), types of motivation (autonomous/control), selfefficacy, agentic engagement, and mathematics academic achievement in a sample of university students from Lima. The sample was composed of 165 students from two public universities of Metropolitan Lima from different careers in science and mathematics. The instruments used in this study had good evidences of validity and reliability. Corresponding correlations and path analyses were conducted to explain the direct effects of the variables. It was found that the teaching styles of autonomy support and control positively predicted autonomous motivation and control motivation, respectively. Also, the perception of autonomy support teaching style predicts self-efficacy and agentic engagement. Autonomous motivation is a mediator variable between the teaching style of autonomy support and self-efficacy. The relationship between academic achievement and the perception of autonomy support teaching style is mediated by self-efficacy. Also, this variable mediated the relationship between the teaching style of autonomy support and agentic engagement. On the other hand, the relationship between perception of control teaching style and agentic disengagement is mediated by the control motivation. Finally, results are discussed and recommendations, limitations and future lines research suggestions are provided.

Full textThe difficulty of coordinating a group of mobile robots is adressed in this thesis by investigating control architectures which aim to break task complexity. In fact, multi-robot navigation may become rapidly inextricable, specifically if it is made in hazardous and dynamical environment requiring precise and secure cooperation. The considered task is the navigation of a group of mobile robots in unknown environments in presence of (static and dynamic) obstacles. To overcome its complexity, it is proposed to divide the overall task into a set of basic behaviors/controllers (obstacle avoidance, attraction to a dynamical target, planning, etc.). Applied control is chosen among these controllers according to sensors information (camera, local sensors, etc.). The specificity of the theoretical approach is to combine the benefits of multi-controller control architectures to those of multi-agent organizational models to provide a high level of coordination between mobile agents-robots systems. The group of mobile robots is then coordinated according to different norms and specifications of the organizational model. Thus, activating a basic behavior in favor of another is done in accordance with the structural constraints of the robots in order to ensure maximum safety and precision of the coordinated movements between robots. Cooperation takes place through a supervisor agent (centralized) to reach the desired destination faster ; unexpected events are individually managed by the mobile agents/robots in a distributed way. To guarantee performance criteria of the control architecture, hybrid systems tolerating the control of continuous systems in presence of discrete events are explored. In fact, this control allows coordinating (by discrete part) the different behaviors (continuous part) of the architecture. The development of ROBOTOPIA simulator allowed us to illustrate each contribution by many results of simulations

Il permet aux membres d'un SMA d'utiliser l'écoute flottante pour se structurer en groupes centrés sur des leaders afin de s'adapter aux conditions de communication limitées et dynamiques dont ils disposent. Ce modèle fournit un cadre dans lequel les agents peuvent évoluer et assure que si leurs décisions respectent certaines contraintes (notamment de cohérence) ils pourront tirer parti de tous les messages qu'ils pourront recevoir (même s'ils ne leur sont pas destinés) afin de se forger les croyances les plus cohérentes possibles sur l'organisation de l'équipe et ainsi faciliter son activité.
D'une part, nous développons plusieurs éléments utiles pour exploiter ce modèle en étoile (langage à la sémantique définie formellement, mécanisme de mise à jour et algorithme associé). D'autre part, deux séries d'expérimentations (OTTO et LOTTO) nous permettent d'étudier le comportement du modèle face aux variations de divers paramètres.

Full textActual network and service management solutions are facing an increasing complexity of both, the resources that have to be managed and the management functions to deploy. This difficulty has recently contributed to the birth of the self-management vision which consists in minimizing the interventions of the human administrator within the different phases of the management activity. The general contribution of our work proposes concepts, methods and mechanisms to facilitate the conception of self-management solutions. Its originality is based on the combination of an organizational and informational framework – emanating respectively from the domains of multi-agent systems and information modeling – and on the addition of a cooperative framework ensuring the coherence of this combination. Finally, we have defined a method and implemented a prototype that is available to developers of autonomous management solutions

Full textIn this thesis, we focus on traffic coordination and optimization in road intersections, while accounting for intelligent autonomous vehicles. This thesis is organized in two parts. The first part focuses on the problem of sharing a one-lane road between two opposite flows of vehicles. The state of the art shows few studies addressing this issue. We propose two reactive coordination approaches that minimize vehicle delays and measure their performances statistically through simulations. The second part of the thesis addresses the problem of generic traffic management in a traffic network. We develop a stop-free approach that explores a principle alternating vehicles between flows at intersections, and it provides distributed algorithms optimizing this alternation at each intersection and in the overall network. We present the modeling choices, the algorithms and the simulation study of our approach and we compare its performances with existing approaches

Full textArtificial intelligence (AI) has been widely integrated, especially in the automotive industry where autonomous cars are becoming more common. As more and more cars get autonomous functions, the drivers' previous role changes. Drivers go from manually operating the car to monitoring it, so that the autonomous functions work. As the driver's role changes, challenges arise for drivers' experiences for autonomous functions. The purpose of the study is to identify these challenges that lead to the question: What challenges does the design of initiative shift in autonomous cars in relation to perceived trust entail? To create understanding, a qualitative study has been conducted where a design ethnographic approach was used as the basis for the presented illustration. The participants in the study were people who own a car with autonomous functions. The study contributes with knowledge of how perceived reliance in relation to the change in initiative that takes place in autonomous cars, which is presented in an illustration. The conclusion reflects societal and ethical challenges regarding the design of autonomous cars.

Full textIn this work, we propose a new solution to agent navigation based upon boundary value problems (BVP), called Configurable Flows, to control steering behaviors of characters in dynamic environments. We use a potential field formalism that allows synthetic actors to move negotiating space, avoiding collisions, and attaining goals while producing very individual paths. The individuality of each character can be set by changing its inner field parameters leading to a broad range of possible behaviors without jeopardizing its performance. BVP Path Planners generate potential fields through a differential equation whose gradient descent represents navigation routes from any point of the environment to a goal position. Resulting paths are smooth and free from local minima. In spite of these advantages, these kind of planners consumes a lot of time to produce a solution. Our approach combines a BVP Path Planner with the Full Multigrid Method, which solves elliptic partial differential equations using a hierarchical strategy. The proposed planner enables real-time performance in large environments. Results show that our proposal spends less than 1% of the time needed to compute a solution using the original BVP planners in several environments. We refine our Path Planner by introducing a new form of the core equation that permits to easily cope with terrain inhomogeneities. This is accomplished by locally changing the concavity/ convexity of the potential, and then creating regions with higher or lower navigation preferences. As the potential field requires several steps to converge, this approach can be expensive computationally. To overcome this problem, we integrate this novel core equation to the hierarchical planner, emerging a wide variety of applications. We believe our proposal can contribute to several areas of research including agent navigation, pathfinding for games, crowd simulation and robotics. Our publications reinforce the relevance of the proposed method.

Full textFor several years, distributed virtual environments (DVEs) have been increasingly popular in the form of online video games, training simulators or collaborative virtual environments. Nowadays, such applications often include computer simulated autonomous entities to provide densely populated virtual worlds. However, most current DVEs involve static behavioral models which are not much sensitive to bandwidth limitations, packet loss, latency or jitter. In this context, the first achievements presented deal with the simulation of autonomous adaptive entities in a High Level Architecture-based DVE. They raise some issues related to the effects of distribution on such entities' capabilities to make complex behaviors emerge. To minimize those drawbacks, an approach based on management areas is put forward to reduce the amount of interactions that rely on network communications. This document finally describes a mechanism designed to optimise the dead reckoning algorithm which goal is to reduce the amount of exchanged messages using entity state prediction

Full textRobots will be more and more used in both civil and military fields. These robots, operating in fleet, can accompany soldiers in fight, or accomplish a mission while being supervised by a control center. Considering the requirement of a military operation, it is complicated to let robots decide their action without an operator agreement or watch, in function of the situation.In this thesis, we focus on two problematics:First, we try to exploit adjustable autonomy to make a robot accomplishes is mission as efficiency as possible, while he respects restrictions, assigned by an operator, on his autonomy level. For this, it is able to define for given sets of states and actions a restriction level. This restriction can force, for example, the need of being tele-operated to access a dangerous zone.Secondly, we consider that several robots can be deployed at the same time. These robots have to coordinate to accomplish their objectives. However, since operators can take the control of some robots, the coordination is harder. In fact, the operator has preferences, perception, hesitation, stress that are not modeled by the agent. It is then hard to estimate his next actions, so to coordinate with him. We propose in this thesis an approach to estimate the policy executed by a tele-operated robot from learning methods, based on observed actions from this robot.The notion of planning his important in these works. These are based on planning models, such as Markov Decision Processes

Full textUnderwater marine applications are nowadays branching into various fields covering larger and deeper zones. Performing the required tasks with the aid of AUV flotillas is a real challenge. However, the advantages of using such a new technology are numerous. Firstly, this would highly reduce the cost of the mission thanks to the distribution of this former among the various AUV: the loss of one AUV or its bad functioning will not degrade the performance of the flotilla in general. Secondly, the use of a flotilla reduces the execution time of a mission given the parallelization of certain tasks. Finally, any mission can be accomplished by the flotilla by taking into consideration the specificity of each AUV. In fact, each of these vehicles holds different characteristics rendering the global architecture heterogeneous and therefore applicable in different contexts. However, the methods concerned with multi-AUV cooperation are hindered by two main limitations: (1) the number of communications induced and (2) the management of the heterogeneity in the flotilla.The proposed approach aims at responding to these challenges. The principal idea is to combine this reactive cooperational approach with an organizational one. The reactive cooperational approach allows the exchange of simple communication signals. However, it does not help in solving the problems of cooperation that are very constrained and that mainly concern the spatial coordination of homogeneous vehicles. The first contribution in this thesis is the extension of the satisfaction-altruism approach. A new reactive decisional mechanism capable of considering the cooperative actions of various natures is proposed. The second contribution consists in specifying the context of reactive interactions based on an organizational approach. The organizational model Agent/Group/Role is used in order to have an explicit representation of the flotilla. The concepts of "group" and especially "role" are used in the attribution of the communication signals allowing the accomplishment of heterogeneous interactions with a big modularity. A new concept is therefore born and is integrated in a new software architecture called REMORA intended to equip autonomous underwater vehicles. This proposed new method has been validated through various numerical simulations in different scenarios putting at stake heterogeneous AUV
