ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / The National Oceanic and Atmospheric Administration (NOAA) Jason Ground System (NJGS) is a consolidated next-generation ground system that will support the simultaneous operation of the OSTM/Jason-2 and Jason-3 ocean surface topography missions. The NJGS will consist of several independent subsystems for spacecraft command and control, telemetry processing, and data archiving and distribution. The existing NOAA Jason-2 Ground System (J2GS) was designed around the concept of subsystem "strings", in which two complete sets of subsystems acted in primary and standby roles. For the NJGS, this concept is replaced with subsystem-level redundancy, in which two or more instances of each subsystem independently provide redundant capabilities. This paper discusses the design elements involved in the provision of a ground system architecture providing redundancy at the subsystem level. The paper focuses on the interaction between primary and standby subsystems and the mechanism through which failover capabilities are provided across the ground system.

Um dos problemas do paradigma BDI quando se integram agentes a ambientes virtuais ou simuladores é a ausência de controle sobre as suas percepções. Não havendo alguma forma de percepção direcionada ao objetivo, o agente pode ser inundado por informações irrelevantes causando um aumento injustificado do tempo de processamento. Com o objetivo de fornecer um maior controle sobre as percepções do agente e reduzir o seu tempo de resposta, este trabalho apresenta um mecanismo de filtragem das percepções para o interpretador Jason que visa eliminar aquelas percepções que podem ser ignoradas. Para tal, foram propostos e implementados alguns tipos de filtros pré-definidos, que foram aplicados a três cenários diferentes. Através de validações estatísticas apropriadas, mostrou-se que a aplicação de filtros de percepção pode reduzir em até 80% o tempo de processamento de um agente, sem afetar significativamente o seu desempenho medido em termos de sua função de utilidade. / When agents are supposed to be integrated to virtual environments virtual or simulators, one of the BDI paradigms major concerns is the lack of control over the agents perceptions. Without having any form of goal directed perceptions, the agent may be flooded by irrelevant information thus causing an unjustified increase in processing time. In order to provide greater control on the agents perceptions and to reduce its time response, this work presents a filtering perception mechanism for the Jason interpreter, aimed at eliminating those perceptions that can be ignored. To this end, some types of pre-defined filters have been proposed, implemented, and applied to three different scenarios. Through appropriate statistical validation methods, it was shown that applying perception filters can reduce up to 80 % of an agents processing time, without significantly affecting its performance measured in terms of its utility function.

A significant challenge in the Wireless Sensor Networks (WSN) research field is to find flexible and energy efficient strategies to perform the network setup and configuration to accomplish specified sensing missions. This thesis presents an approach which uses mobile agents to disseminate and allocate sensing missions to the sensor nodes. The addressed problem refers to the selection of appropriate nodes to perform the sensing mission, by using a decentralized approach supported by mobile software agents. Traditional approaches to deal with WSN setup use the pre-planned strategies, which are deliberately modelled, designed and tuned before the network deployment, and thus are not flexible. This thesis presents an alternative approach based on Belief Desire Intention-model agents using JASON, instead of traditional approaches. Simulation results provides evidences that this approach can achieve the goals of a sensing mission setup by decisions autonomously taken by the sensor node, diminishing then the need for communication among the sensor nodes, hence saving energy resources.

Depuis l'arrivée au pouvoir du gouvernement conservateur de Stephen Harper, les réformes du système migratoire se sont succédées les unes après les autres. C'est d'abord au ministre Jason Kenney à qui le premier ministre a confié la tâche de réformer en accéléré le système d'immigration canadien. En poste entre 2008 et 2013, il a procédé à une quantité importante de réformes. Cela constitue un tournant dans l'histoire politique canadienne. Pour mieux comprendre les politiques publiques en immigration, cette thèse se penche sur le rôle et l'influence exercée par les médias sur les réformes de 2010 et de 2012, de leur présentation devant le Parlement à leur adoption. Souvent laissés de côté par les spécialistes de l'immigration, la thèse reconnaît que les médias sont l'un des facteurs externes ayant eu un effet sur la politique d'immigration pendant l'ère Kenney. Leur influence s’exerce à un moment précis. Lors de l’étude des réformes devant le Parlement, les médias exercent une influence non négligeable grâce à leur habileté à sensibiliser le public sur certains sujets précis et par la suite en guidant son jugement, dominant ainsi l’ordre du jour des affaires publiques.

The goal of this master's thesis is to design and implement agent system for dealing with sportsmen. It will be possible to apply trust and reputation principles on this system. This system is implemented in Jason agent language. Agents there posing as sports club managers. The main target of these managers is to have the maximal profit. The environment of agents is changing by playing the matches between the teams. Players quality evalution follows the played matches. Based on played matches, managers can evaluate the worth of each player and trade them in order to achieve the maximal possible profit. Untrustworthy agents take a place in this system. These agents overvalue their players using inccorect behavior. The experiments will be made within this masters's thesis in order to compare gain of apllication trust and reputation principles.

This thesis serves as an open-ended document of a young artist attempting to sift through his accumulated opinions in order to figure out what it means to accept complicity in the face of auspicious authority, rapid turnover, and paper-thin irony and nihilism, while still striving to stake a claim at something worth making and defending.
