Pour cette thèse, notre matériel clinique est principalement constitué des retranscriptions de séances de travail — que nous avons enregistrées — auxquelles nous avons participé deux ans durant avec l’accord d’un collectif d’enseignants élaborant un projet de collège alternatif au sein de l’Éducation nationale. Nous avons aussi pu écouter et recueillir des témoignages de quelques membres d’une autre équipe de professeurs travaillant dans un microlycée, selon des modalités coopératives de fonctionnement, depuis une dizaine d’années pour les plus anciens. Notre objectif étant de nous intéresser à des pratiques coopératives, au désir du faire équipe avec d’autres, aux valeurs qui les sous-tendent, ainsi qu’aux idéaux comme aux fantasmes qui sont actifs à l’insu des sujets. Lors du travail d’écoute de certaines verbalisations, se révélait un fantasme inconscient d’égalité parfaite, chez nombre de membres, ce qui nous a conduites vers l’idée d’un désir particulier soutenu par ce fantasme : le désir-totalité. Or, lorsque ce fantasme et ce désir ne sont pas aperçus, reconnus, élaborés, puis dépassés, ils font entrave, dans la pratique, au plaisir d’être et de coopérer avec les autres. Pour les surmonter, une distanciation avec soi-même est nécessaire, c’est-à-dire, un décentrement d’avec ses propres objets de pensée. Ceci s’est produit pour tous les membres qui sont restés et les nouveaux venus aux fils du temps. / For this thesis, our clinical material consists mainly of audio-transcripts of working sessions - that we recorded - in which we participated for two years with the agreement of a collective of teachers developing an alternative junior high school project within the National Education. We have also been able to listen to and collect testimonials from some members of another team of teachers working in a micro-high school, according to co-operative modalities of functioning, since ten years for older ones. Our goal was to focus on cooperative practices, the desire to team up with others, the values that underlie them, ideals and fantasies that are active without the knowledge of the subjects. During the work of listening to certain verbalizations, an unconscious fantasy of perfect equality was revealed in many members, which led us to the idea of a particular desire supported by this fantasy: desire-totality. Now, when this fantasy and desire are not perceived, recognized, elaborated and then exceeded, they hinder, in practice, the pleasure of being and of cooperating with others. To overcome them, a distancing with oneself is necessary that is to say, a decentering from one's own objects of thought. Over the times, this has happened to all members who have stayed as well as to newcomers.

abstract: This increasing role of highly automated and intelligent systems as team members has started a paradigm shift from human-human teaming to Human-Autonomy Teaming (HAT). However, moving from human-human teaming to HAT is challenging. Teamwork requires skills that are often missing in robots and synthetic agents. It is possible that adding a synthetic agent as a team member may lead teams to demonstrate different coordination patterns resulting in differences in team cognition and ultimately team effectiveness. The theory of Interactive Team Cognition (ITC) emphasizes the importance of team interaction behaviors over the collection of individual knowledge. In this dissertation, Nonlinear Dynamical Methods (NDMs) were applied to capture characteristics of overall team coordination and communication behaviors. The findings supported the hypothesis that coordination stability is related to team performance in a nonlinear manner with optimal performance associated with moderate stability coupled with flexibility. Thus, we need to build mechanisms in HATs to demonstrate moderately stable and flexible coordination behavior to achieve team-level goals under routine and novel task conditions. / Dissertation/Thesis / Doctoral Dissertation Engineering 2017

The realm of autonomous robotics has seen impressive advancements in recent years, with robots taking on essential roles in various sectors, including disaster response, environmental monitoring, agriculture, and healthcare. As these highly intelligent machines continue to integrate into our daily lives, the pressing imperative is to elevate and refine their performance, enabling them to adeptly manage complex tasks with remarkable efficiency, adaptability, and keen decision-making abilities, all while prioritizing safety-aware navigation, mapping, and control systems. Ensuring the safety-awareness of these robotic systems is of paramount importance in their development and deployment. In this research, bio-inspired neural networks, nature-inspired intelligence, deep learning, heuristic algorithm and optimization techniques are developed for safety-aware autonomous robots navigation, mapping and control. A bio-inspired neural network (BNN) local navigator coupled with dynamic moving windows (DMW) is developed in this research to enhance obstacle avoidance and refines safe trajectories. A hybrid model is proposed to optimize trajectory of the global path of a mobile robot that maintains a safe distance from obstacles using a graph-based search algorithm associated with an improved seagull optimization algorithm (iSOA). A Bat-Pigeon algorithm (BPA) is proposed to undertake adjustable speed navigation of autonomous vehicles in light of object detection for safety-aware vehicle path planning, which can automatically adjust the speed in different road conditions. In order to perform effective collision avoidance in multi-robot task allocation, a spatial dislocation scheme is developed by introduction of an additional dimension for UAVs at different altitudes, whereas UAVs avoid collision at the same altitude using a proposed velocity profile paradigm. A multi-layer robot navigation system is developed to explore row-based environment. A directed coverage path planning (DCPP) fused with an informative planning protocol (IPP) method is proposed to efficiently and safely search the entire workspace. A human-autonomy teaming strategy is proposed to facilitate cooperation between autonomous robots and human expertise for safe navigation to desired areas. Simulation, comparison studies and on-going experimental results of optimization algorithms applied for autonomous robot systems demonstrate their effectiveness, efficiency and robustness of the proposed methodologies.

Approved for public release; distribution in unlimited. / This thesis represents a cross Systems Command (NAVSEA/NAVAIR) developed product. The product - the Sunset Supply Base (SSB) system - provides a complete system for addressing the risks and supportability issues involved with Commercial Off the Shelf (COTS) products in Navy combat and support systems. The SSB system was implemented on three Navy combat weapon systems at various phases of the product development life cycle. The main body provides to the Program Management Offices (PMO) and other decision makers, a high level summary of performance expectations. Appendix A - The Sunset Supply Base Architecture - identifies at a high level of abstraction a collaborative architecture providing a roadmap for design and development of the SSB system. Appendix B - The Systems Engineering Development and Implementation (SEDI) plan - is a prescriptive or "How to" manual describing activities that have been used to successfully implement the SSB system. Appendix C - Business Case Analysis (BCA) - presents the data collected as a result of SEDI plan implementation then addresses the business/programmatic attributes showing the viability and value proposition possible through the SSB system. Appendix D - The Marketing Plan for the SSB system - defines methods and practices necessary to establish the SSB system as the alternative of choice. / Chemical Engineer, United States Navy / Systems Engineer, United States Navy
