[pt] DEFICIÊNCIA VISUAL E AMBIENTE MUSEAL: COMO O ESPAÇO AFETA A EXPERIÊNCIA DE VISITA AO MUSEU / [en] VISUAL IMPAIRMENT AND THE EXHIBITION SPACE: HOW THE ENVIRONMENT AFFECTS THE MUSEUM EXPERIENCEEVELINE HELENA ALMEIDA DE SOUZA 11 June 2021 (has links)
[pt] O espaço expositivo pode tanto se apresentar de forma acolhedora, representando uma possibilidade para o visitante com deficiência visual de explorar seus outros sentidos e vivenciar a exposição de uma maneira própria, como também pode se apresentar como um espaço excludente, representando uma série de barreiras e obstáculos que o impedem de usufruir a exposição. A presente dissertação tem como objetivo geral examinar a experiência do visitante com deficiência visual em museus, buscando compreender a relação e a interação entre esse visitante e o ambiente construído do espaço expositivo, bem como a sua relação com as obras e as demais pessoas presentes no local. Como metodologia, foi primeiramente aplicada a revisão bibliográfica, em que procurou-se examinar questões como a relação entre comunicação museológica, ambiente museal e orientação espacial e como esses fatores afetam a experiência de visita para o público em questão. Também foi realizada uma pesquisa documental a fim de verificar as normas, leis e decretos relacionados ao incentivo e implementação da acessibilidade em espaços culturais no Brasil. Posteriormente foram entrevistados visitantes de museu com deficiência visual. A partir dessas entrevistas, fez-se a seleção de alguns museus para um aprofundamento. Essa etapa foi iniciada com observações sistemáticas a fim de investigar e documentar aspectos dos ambientes que haviam sido levantados nas técnicas aplicadas anteriormente, seguidas de entrevistas com gestores responsáveis pelos setores de acessibilidade e/ou educativo com o objetivo de verificar como os espaços lidam com a acessibilidade para esse público. Como resultado pode-se apontar a falta de recursos de acessibilidade para as pessoas com deficiência visual em praticamente todos os museus visitados. As poucas iniciativas encontradas ainda não estão em conformidade com as normas e critérios estabelecidos, contudo podem incentivar a adoção da acessibilidade em outros espaços. Propõe-se a adoção de projetos de Design Inclusivo, bem como o foco na acessibilidade atitudinal. / [en] The exhibition space can be welcoming and inclusive, allowing the visually impaired visitor to explore their other senses and have a unique experience. However, it can also be challenging, presenting a series of barriers and obstacles that prevents the exhibition s understanding and enjoyment. This dissertation investigates the visually impaired visitor s experience in museums, seeking to understand the relationship and interaction between the visitor and the built environment and their relationship with the objects and other people. The methodology applied consisted of a bibliographic review, investigating issues as the relationship among museological communication, museum environment and spatial orientation, and how these factors affect the visiting experience. The review also consisted of documentary research to verify the technical standards, laws, and decrees related to the implementation of accessibility in cultural institutions in Brazil. Subsequently, the researcher conducted interviews with visually impaired visitors. Based on the interviews, some museums were selected for further study. This stage consisted of systematic observations of the chosen museums to check the available resources and observe some of the built environment aspects pointed out by the interviewees followed by interviews with managers responsible for accessibility and educational programs to identify how these spaces deal with accessibility for the visually impaired. This research concludes that there is a lack of accessibility resources for the visually impaired in almost all selected museums. The few initiatives found are still not in conformity with the established standards and criteria; however, these initiatives may encourage accessibility in other cultural spaces. The research proposes the adoption of Inclusive Design projects as well as a focus on attitudinal accessibility.

IT security : Education, Knowledge and Awareness / IT Säkerhet : utbildning, kunskap och medvetenhetSchiöld, Ellinor, Andersson, Sanna January 2022 (has links)
IT systems that contain large volumes of information are today extremely valuable to organizations. As the IT systems grow bigger, more challenges are emerging, vulnerability increases and control decreases. Organizations are using IT security to protect their IT systems from different threats and the human factor can be seen as one of the biggest risks towards IT security. Therefore it is not optimal to only focus on the technical solutions and measures, the focus should also be on the employees IT security knowledge and IT security awareness. To increase the knowledge of IT security and to make the employees more IT security aware requires continuous work and IT security education is often mentioned as a factor to increase IT security- knowledge and awareness. Despite this, challenges are mentioned in previous research, which means that even if an employee participates in an IT security education, the organizations can not take for granted that their employees have gained IT security knowledge or know how to act more security aware. IT security education, IT security knowledge and IT security is mentioned as three factors that can affect IT security. Three research questions were intended to be answered within this research with the purpose to investigate if these factors increase each other. Three hypotheses were also forming the basis for answering the research questions. With a quantitative method and questionnaire this research reached out to 158 employees at different Swedish branches within machine manufacturing, advertising, municipal work and sales industry. Results showed that one of the three hypotheses was accepted and the other two hypotheses were not accepted. This result also gave answers to the research questions regarding that IT security education does not increase IT security knowledge, IT security knowledge does not increase IT security awareness but IT security education increases IT security awareness.

<b>Safety and mobility improvement of mixed traffic using optimization- And Learning-based methods</b>Runjia Du (9756128) 11 December 2023 (has links)
<p dir="ltr">Traffic safety and congestion are global concerns. Autonomous vehicles (AVs) are expected to enhance transportation safety and reduce congestion. However, achieving their full potential requires 100% market penetration, a challenging task. This study addresses key issues in mixed traffic environments, where human-driven vehicles (HDVs) and connected autonomous vehicles (CAVs) coexist. A number of critical questions persist: 1) inadequate exploration of human errors (errors originating from non-CAV sources) in mixed traffic; 2): limited focus on information selection and learning efficiency in network-level rerouting, particularly in highly dynamic environments; 3) inadequacy of personalized element driver inputs in motion-planning frameworks; 4) lack of consideration of user privacy concerns.</p><p dir="ltr">With the goal of advancing the existing knowledge in this field and shedding light on these matters, this dissertation introduces multiple frameworks. These frameworks leverage connectivity and automation to improve safety and mobility in mixed traffic, addressing various research levels, including local-level and network-level safety enhancement, as well as network-level and global-level mobility enhancement. With optimization- and learning-based methods implemented (Model Predictive Control, Deep Neural Network, Deep Reinforcement Learning, Transformer model and Federated Learning), frameworks introduced in this dissertation are expected to help highway agencies and vehicle manufacturers improve the safety and efficiency of traffic flow in the mixed-traffic era. Our research findings revealed increased crash-avoidance rates in critical situations, enhanced accuracy in predicting lane changes, improved dynamic rerouting within urban areas, and the implementation of effective data-sharing mechanisms with a focus on user privacy. This research underscores the potential of connectivity and automation to significantly enhance mixed-traffic safety and mobility.</p>

Look2Hook : The Impact of Menu Design and Input Device on Gaze-based Menu SelectionHirsch, Daniel January 2021 (has links)
In this paper, an investigation of the impact of menu design and input device for gaze-based menu selection tasks is reported. The study investigates the usability, measured by effectiveness, efficiency, and user satisfaction, for gaze-based interaction in realistic, complex menu selection tasks. The study includes three different menu designs, a linear drop-down menu (L1), a radial dynamic menu (R1), and a semi-radial menu (R2), along with two different input devices, a unimodal input device using dwell-time (DT) and a multimodal input device using a combination of gaze and a manual switch (GMS). In a user study with nine test participants, the impact of menu design, input device, and navigation complexity on task completion time, accuracy rate, cognitive load, and quality of use ratings for menu selection tasks were investigated. The usability results confirmed the expectations of the advantages of radial menu designs, with the radial dynamic menu (R1) being better suited for gaze- based interaction than either the linear drop-down menu (L1) or semi-radial menu (R2). The usability results also confirmed the expectations regarding the input device, namely, the multimodal GMS input device was superior to the unimodal DT input device for gaze-based interaction. / I den här studien rapporteras en undersökning av effekterna av menydesign och inmatningsenhet för blickbaserade menyvalsuppgifter. Studien undersöker användbarheten, mätt av verkningsgrad, effektivitet, och användarnöjdhet, för blickbaserad interaktion i realistiska, komplexa menyvalsuppgifter. Studien innefattar tre olika menydesigner, en linjär rullgardinsmeny (L1), en radiell dynamisk meny (R1) och en halvradiell meny (R2), tillsammans med två olika inmatningsenheter, en unimodal inmatningsenhet som använder dwell-time (DT) och en multimodal inmatningsenhet som använder en kombination av blick och en manuell knapp (GMS). I en användarstudie med nio testdeltagare undersöktes effekterna av menydesign, inmatningsenhet och navigeringskomplexitet på tiden för uppgifts slutförandet, noggrannhet, kognitiv belastning och kvalitet på användningsbetyg för menyvalsuppgifter. Användbarhetsresultaten bekräftade förväntningarna om fördelarna med radiella menydesigner, varvid den radiella dynamiska menyn (R1) passar bättre för blickbaserad interaktion än både den linjära rullgardinsmenyn (L1) eller halvradialmenyn (R2). Användbarhetsresultaten bekräftade också förväntningarna avseende inmatningsenheten, nämligen att multimodal GMS-inmatningsenheten var överlägsen den unimodala DT-inmatningsenheten för blickbaserad interaktion.

Safety management in times of crisis: Lessons learned from a nationwide status-analysis on German intensive care units during the COVID-19 pandemicSchmidt, Michelle, Lambert, Sophie Isabelle, Klasen, Martin, Sandmeyer, Benedikt, Lazarovici, Marc, Jahns, Franziska, Trefz, Lara Charlott, Hempel, Gunther, Sopka, Sasa 03 May 2024 (has links)
Background: The status of Safety Management is highly relevant to
evaluate an organization’s ability to deal with unexpected events or errors,
especially in times of crisis. However, it remains unclear to what extent
Safety Management was developed and suffciently implemented within the
healthcare system during the COVID-19 pandemic. Providing insights of
potential for improvement is expected to be directional for ongoing Safety
Management efforts, in times of crisis and beyond.
Method: A nationwide survey study was conducted among healthcare
professionals and auxiliary staff on German Intensive Care Units (ICUs)
evaluating their experiences during the first wave of the COVID-19 pandemic.
Error Management and Patient Safety Culture (PSC) measures served to
operationalize Safety Management. Data were analyzed descriptively and by
using quantitative content analysis (QCA).
Results: Results for n = 588 participants from 53 hospitals show that there is
a gap between errors occurred, reported, documented, and addressed. QCA
revealed that low quality of safety culture (27.8%) was the most mentioned
reason for errors not being addressed. Overall, ratings of PSC ranged from
26.7 to 57.9% positive response with Staffng being the worst and Teamwork
Within Units being the best rated dimension. While assessments showed a
similar pattern, medical staff rated PSC on ICUs more positively in comparison
to nursing staff.
Conclusion: The status-analysis of Safety Management in times of crisis
revealed relevant potential for improvement. Human Factor plays a crucial role
in the occurrence and the way errors are dealt with on ICUs, but systemic
factors should not be underestimated. Further intensified efforts specifically in
the fields of staffng and error reporting, documentation and communication
are needed to improve Safety Management on ICUs. These findingsmight also
be applicable across nations and sectors beyond the medical field.

Conception générique d'un outil de configuration de « e-TP » / Generic design of a configuration tool for e-Hands-on-TrainingArnous, Saher 30 September 2014 (has links)
Renforcés par les avancées technologiques des « Sciences et Technologies de l’Information et de la Communication (STIC) », les Travaux Pratiques électroniques « e-TP » sont devenus un mode d’enseignement incontournable surtout dans les disciplines techniques et scientifiques. Plusieurs modes d’e-TP ont émergé : TP virtuel, TéléTP, TP présentiel assisté par ordinateur, TP en réalité augmentée... ces derniers modes nécessitant l'usage de dispositifs matériels (maquette pédagogique, appareils de mesure, robots, etc.). Dans la majorité des cas, avant ou même pendant une session d'e-TP, il est nécessaire de (re)configurer ces dispositifs selon des besoins pédagogiques. Cette reconfiguration nécessite, pour des systèmes complexes, comme les Systèmes Automatisés de Production (SAP), des compétences que l'instructeur ne possède pas systématiquement. Ce qui impose la présence d'un technicien ou limite le nombre d'instructeurs susceptibles d'utiliser la plate-forme pédagogique. Ce travail de recherche a pour objectif de faciliter la (re)configuration de systèmes complexes, particulièrement les SAP, dans le cadre d'e-TPs. Une première enquête auprès des utilisateurs de l’« AIP-Priméca-RAO » (situé à l’INSA de Lyon) a révélé les besoins et contraintes liés à une plate-forme de ce type. Il s'est avéré qu'au-delà de la (re)configuration, l'absence d'outil commun de gestion des ressources pédagogiques faisait perdre un temps précieux aux utilisateurs. Ce constat a nourri la conception d'un outil informatique gérant une chaîne éditoriale dont le but est de simplifier la création, l’édition, l’assemblage, l’organisation et la réutilisation des différentes ressources à exploiter dans une session d’e-TP. Cet outil a également pour objectif d’améliorer l’autonomie de l’instructeur lors de la préparation de sessions d’e-TP tout en réduisant le temps requis pour configurer cette session. Cela a impliqué d’automatiser le processus de reconfiguration du SAP support d'e-TP, et de publication des scénarios pédagogiques sur un système de gestion d’apprentissage « LMS » (Learning Management System). Un prototype a été développé et testé sur des e-TPs réels afin de valider cette conception. Cet outil pourrait, ultérieurement, être rendu plus générique afin de servir des e-TPs dans d'autres disciplines. / Powered by the technological advances of the “Information and communication sciences and technologies”, the Electronic Laboratory for Practical Training “ELab” (also known as ELab hands-on training) has become an inescapable teaching mode especially in the technical and scientific disciplines. Thus, several ELab modes have emerged: virtual ELab, remote ELab, Local Elab, augmented reality ELab, etc. The latter require the use of hardware devices (educational mock ups, measuring instruments, robots, etc.). In most cases, before or during an ELab session, these devices need to be reconfigured according to teaching purposes. For complex systems, like Automated Production Systems (APS), this reconfiguration process requires technical skills which the instructor does not have systematically. This imposes that a technician should be available, failing which the usage of the pedagogical platform will be limited to a few skilled instructors. Accordingly, this research aims at facilitating the reconfiguration process of complex systems (particularly the APS) featuring ELabs. A first survey designated to the users of « AIP-Priméca-RAO », located at the INSA de Lyon, has revealed the needs and constraints related to such a platform. It has been highlighted that beyond the (re)configuration process, a waste of precious time was detected. It has been established that it was due to the absence of a common tool for pedagogical resource management. This observation fed the design of a software tool managing an editorial chain aiming at simplifying creation, edition, assembling, organization, and the reutilization of different resources that can be exploited in an ELab session. This tool is also intended to improve the autonomy of the instructor during the preparation of an ELab session, by reducing the required time to configure this session. This implies to automate the reconfiguration process of an APS supporting the ELab and the publishing of the pedagogical learning scenarios on a Learning Management System (LMS). In order to validate this design, a prototype has been developed and tested on real Elab cases. Subsequently, this tool could be rendered more generic so that it can serve Elabs in different disciplines.

L'impact de l'ouverture économique sur les institutions internes : le cas de la Russie / The impact of the economic openness on the internal institutions : the case of RussiaEgorova-Legon, Irina 21 February 2013 (has links)
Cette thèse propose une analyse du développement économique à partir du concept de facteur humain qui apparaît en économie institutionnelle à travers les institutions informelles. Ces dernières sont responsables du caractère spécifique de chaque structure institutionnelle nationale qui forme le cadre incitatif de l'économie. Composée de règles formelles et informelles, la structure institutionnelle représente un ensemble évolutif. L'objectif élargi de cette recherche est donc de comprendre l'évolution et le changement des structures institutionnelles en étudiant particulièrement l'impact international sur ce processus. L'objectif spécifique de ce travail est d'appliquer l'approche développée au cas de la Russie afin de contribuer à une meilleure compréhension de la structure institutionnelle russe actuelle, de son efficacité pour le développement économique du pays et de l'impact de l'ouverture économique sur son changement, et notamment sur le facteur humain russe. Avec l'adhésion de la Russie en 2012 à l'Organisation Mondiale du Commerce cette question est d'intérêt particulier car le pays s'ouvre aux nouveaux attributs de la mondialisation. En mobilisant le cadre théorique croisé entre l'économie institutionnelle, l'économie de développement et l'économie internationale, cette étude nous conduit à présenter la mondialisation en tant que processus institutionnel qui en généralisant les institutions formelles de l'économie de marché et de la démocratie à l'échelle planétaire, a ignoré le rôle du facteur humain local. Cela explique la différence des performances économiques des pays qui ont adopté les mêmes cadres organisationnels. En revanche, la prise en considération du facteur humain dans l'analyse économique permet de développer la vision plus optimiste de la mondialisation. En facilitant le contact direct entre les représentants des structures institutionnelles différentes, elle est capable de stimuler l'évolution des normes de comportement improductif vers les valeurs sociales incitant les actions productives. En appliquant ce constat à l'analyse de la structure institutionnelle russe qui a vu diverger ses institutions formelles et informelles en résultat des réformes de la transition des années 1990, il est possible de conclure que l'ouverture économique de ce pays dans les conditions actuelles favorisera le changement de son facteur humain. Compte tenu de l'incohérence entre le cadre formel et les institutions informelles russes, l'évolution de ces dernières contribuera à l'instauration de l'ordre social formel et impersonnel. / This PhD dissertation analyzes the economic development from the concept of human factor which appears in the Institutional Economics trough the informal institutions. These institutions are responsible for the specific character of each national institutional structure which forms the incentive system of an economy. An institutional framework as a composite of formal rules and informal institutions is an evolutionary set. The wider objective of this thesis is to understand the evolution and change of institutional structures by studying in particular the international impact on this process. The specific objective of this research work is to apply the developed approach to the Russian case in order to better understand the actual Russian institutional structure, its effectiveness for the economic development of the country and the impact of the economic openness on the institutional change, in particular on the Russian human factor. This impact is a highly topical question for Russia because of its greater economic openness due to its accession to the World Trade Organization completed in 2012. Within the theoretical framework formed by Institutional Economics, Development Economics and International Economics, this research leads us to present the globalization as an institutional process which generalized formal institutions of the market economy and the democracy on the global scale but which ignored the role of the local human factor. It explains the differences of the economic performance in the countries who adopted the same formal framework. In contrast, taking into account the role of the human factor in the economic development allows to develop more optimistic views of globalization. By facilitating the direct contact between the representatives of the different institutional structures, the globalization can stimulate the evolution of social norms of unproductive behavior to the social values inciting productive actions. Applying this to the Russian framework which formal and informal institutions became strongly divergent in result of the transition reforms of 1990s, it is possible to conclude that the economic openness of this country in the actual situation will favor the change of its human factor. Considering the incoherence between Russian actual formal framework and Russian informal institutions, the evolution of the last will contribute to establish former and impersonal social order.

Dött utrymme : En studie om olyckor i slutna utrymmenJohansson, Viktor, Kristensson, Tommie January 2018 (has links)
Begreppet slutna utrymmen definieras som ett utrymme utan tillräcklig ventilation, som ej är utformat för kontinuerlig vistelse. Regelverk och flertalet rekommendationer gällande kraven på atmosfäriska mätningar har framtagits för att begränsa riskerna med att gå in i slutna utrymmen men ändå fortsätter olyckor att inträffa, olyckor där just atmosfären är den avgörande faktorn. Den här studien har med hjälp av analysmodellen Human Factors Analysis and Classification System – Maritime Accidents (HFACS-MA) kvalitativt analyserat 14 haverirapporter där personer har omkommit eller blivit svårt skadade på grund av syrebrist eller exponering för toxiska gaser i slutna utrymmen ombord på fartyg och sedan sammanställt resultaten för att få en bild över de främst bidragande anledningarna till olyckorna. Undersökningen har även analyserat räddningsaktionernas kvalitet på olika fartygstyper baserat på resultat från HFACS-MA analyserna och utlåtanden från haveriutredare och har även undersökt vilka förbättringar som kan göras för att räddningsaktioner i slutna utrymmen ska fungera så effektivt som möjligt. Studien fann att de främsta anledningarna till olyckor i slutna utrymmen, där just atmosfären är den avgörande faktorn, är bristande översyn från arbetsledare följt av överträdelser från den enskilde personen och problem med organisationen ombord. Resultaten pekar även på att tankfartyg har bättre räddningsorganisationer är torrlastfartyg, vilket genom jämförelse med andra studier kan härledas till att tankrederier fokuserar mer på säkerhetsledning än torrlastbranschen. Gällande förbättring av räddningsaktioner så har studien kommit fram till att besättningar borde öva mer i slutna utrymmen för att få bättre rutin på räddningsaktionerna så att dessa utförs med kunskap och träning istället för känslor och instinkt. / The term ”Enclosed space” is defined as a space with limited or no ventilation and which is not designed for continuous occupancy. Rules and several recommendations concerning the requirements for atmospheric measurements have been drafted to limit the risks involving enclosed spaces but still, accidents keep occurring, accidents where the atmosphere is the cardinal factor. This study has, with the aid of the analysis module Human Factors Analysis and Classification System – Maritime Accidents (HFACS-MA), qualitatively analyzed 14 accident reports where persons have perished or been severely injured due to lack of oxygen or exposure to toxic gases in enclosed spaces aboard ships. The results have then been compiled to get a broad picture of the most contributing causes for the accidents. The study has also analyzed the rescue operation’s quality on different types of vessels based on the HFACS-MA results and statements from the investigators and the study have also looked at what improvements can be made to ensure that rescue operations in enclosed spaces will work as effectively as possible. The study found that the most contributing causes for accidents in enclosed spaces, where the atmosphere was the cardinal factor, is the lack of supervision from supervisors followed by violations by individuals and organizational issues. The results suggest that tanker vessels have a better rescue organization compared to dry cargo vessels, which by comparison with earlier studies can be explained by the higher focus on safety management by tanker companies compared to dry cargo companies. When it comes to improving rescue operations, this study has concluded that crews should practice more in enclosed spaces in order to get a better routine so that the rescue operations are made based on knowledge and training instead of emotions and instinct.

Vers une interaction humain-robot à une initiative mixe : une équipe coopérative composée par des drones et un opérateur humain / Towards mixed-initiative human-robot interaction : a cooperative human-drone team frameworkUbaldino de Souza, Paulo Eduardo 19 October 2017 (has links)
L’interaction homme-robot est un domaine qui en est encore à ses balbutiements.Les développements se sont avant tout concentrés sur l’autonomie et l’intelligence artificielle et doter les robots de capacités avancées pour exécuter des tâches complexes. Dans un proche avenir, les robots développeront probablement la capacité de s’adapter et d’apprendre de leur environnement. Les robots ont confiance, ne s’ennuient pas et peuvent fonctionner dans des environnements hostiles et dynamiques - tous des attributs souhaités à l’exploration spatiale et aux situations d’urgence ou militaires. Ils réduisent également les coûts de mission, augmentent la flexibilité de conception et maximisent la production de données. Cependant, lorsqu’ils sont confrontés à de nouveaux scénarios et à des événements inattendus, les robots sont moins performants par rapport aux êtres humains intuitifs et créatifs (mais aussi faillibles et biaisés). L’avenir exigera que les concepteurs de mission équilibrent intelligemment la souplesse et l’ingéniosité des humains avec des systèmes robotiques robustes et sophistiqués. Ce travail de recherche propose un cadre formel, basé sur la théorie de jeux, pour une équipe de drones qui doit coordonner leurs actions entre eux et fournir à l’opérateur humain des données suffisantes pour prendre des décisions « difficiles » qui maximisent l’efficacité de la mission, selon certaines directives opérationnelles. Notre première contribution a consisté à présenter un cadre décentralisé et une fonction d’utilité pour une mission de patrouille avec une équipe de drones. Ensuite, nous avons considéré l’effet de cadrage, ou « framing effect » en anglais, dans le contexte de notre étude,afin de mieux comprendre et modéliser à terme certains processus décisionnels sous incertitude.Ainsi, nous avons réalisé deux expérimentations avec 20 et 12 participants respectivement. Nos résultats ont révélé que la façon dont le problème a été présenté (effet de cadrage positif ou négatif), l’engagement émotionnel et les couleurs du texte ont affecté statistiquement les choix des opérateurs humains. Les données expérimentales nous ont permis de développer un modèle d’utilité pour l’opérateur humain que nous cherchons à intégrer dans la boucle décisionnelle du système homme-robots. Enfin, nous formalisons et évaluons l’ensemble du cadre proposé où nous "fermons la boucle" à travers une expérimentation en ligne avec 101 participants. Nos résultats suggèrent que notre approche permet d’optimiser le système homme-robots dans un contexte où des décisions doivent être prises dans un environnement incertain. / Human-robot interaction is a field that is still in its infancy. Developments havefocused on autonomy and artificial intelligence, and provide robots with advanced capabilitiesto perform complex tasks. In the near future, robots will likely develop the ability to adapt andlearn from their surroundings. Robots have reliance, do not get bored and can operate in hostileand dynamics environments - all attributes well suited for space exploration, and emergency ormilitary situations. They also reduce mission costs, increase design flexibility, and maximizedata production. However, when coped with new scenarios and unexpected events, robots palein comparison with intuitive and creative human beings. The future will require that missiondesigners balance intelligently the flexibility and ingenuity of humans with robust and sophisticatedrobotic systems. This research work proposes a game-theoretic framework for a drone teamthat must coordinate their actions among them and provide the human operator sufficient datato make “hard” decisions that maximize the mission efficiency, according with some operationalguidelines. Our first contribution was to present a decentralized framework and utility functionfor a drone-team patrolling mission. Then, we considered the framing effect in the context of ourstudy, in order to better understand and model certain human decision-making processes underuncertainty. Hence, two experiments were conducted with 20 and 12 participants respectively.Our findings revealed that the way the problem was presented (positive or negative framing), theemotional commitment and the text colors statistically affected the choices made by the humanoperators. The experimental data allowed us to develop a utility model for the human operatorthat we sought to integrate into the decision-making loop of the human-robot system. Finally,we formalized and evaluated the close-loop of the whole proposed framework with a last onlineexperiment with 101 participants. Our results suggest that our approach allow us to optimize thehuman-robot system in a context where decisions must be made in an uncertain environment.

ANÁLISE CRÍTICA DOS CUSTOS DE IMPLEMENTAÇÃO DE SISTEMA DE GESTÃO DE ESTOQUES EM INDÚSTRIAS METALÚRGICAS DE PEQUENO E MÉDIO PORTE / REVIEW ON THE IMPLEMENTATION COSTS OF THE STOCK MANAGEMENT SYSTEM IN SMALL METALLURGICAL INDUSTRIESRomio, Alexsandra Matos 04 July 2012 (has links)
Due to the necessity of knowing the stocks in an increasingly accurate way in order
to plan sales and production with the dynamics required by the market, more and
more companies have been searching for stock control tools such as computerized
systems, aiming at highly accurate and reliable results. The uncertainty about the
positive results in this kind of investment, especially for the small metallurgical
industries, is an unknown, since the financial and staff resources are sparse. Thus,
the present paper aims at analyzing what issues are connected with the failure in the
investments in computerized stock control tools, and also which are the most
commonly used tools by this type of organization in Brazil. For that, we have
researched works on the success analysis in investments and stock control theories,
besides analyzing which tools are being adopted. It was also developed a case study
in a metallurgical industry within the state of Rio Grande do Sul with the purpose of
quantify this type of investment and the reasons why the stocks management
involving computerization in small metallurgical industries have no been obtaining
positive results. Starting from the negatives, we developed the scope for the
accomplishment of a replanning, and subsequently, we made a new analysis of the
situation with satisfactory results being already observed, as shown. / Com a necessidade de conhecer os estoques de forma cada vez mais precisa, a fim
de planejar as vendas e a produção com o dinamismo que o mercado exige, mais
empresas têm buscado ferramentas de controle de estoque, como sistemas
informatizados, almejando resultados com alta precisão e confiabilidade. A incerteza
de resultados positivos, nesse tipo de investimento, especialmente para metalúrgicas
de pequeno porte, é uma incógnita, já que os recursos de pessoal e financeiro são
limitados. Dessa forma, esse trabalho visa a analisar quais os problemas vinculados
com insucessos nos investimentos em sistemas informatizados de controle de
estoque, bem como quais são as ferramentas mais utilizados atualmente, no Brasil,
por esse tipo de organização. Para tal, foram pesquisados trabalhos sobre análise
de sucesso nos investimentos e teorias de controle de estoque, além de terem sido
analisadas quais ferramentas estão sendo adotadas. Também foi feito um estudo de
caso em uma metalúrgica no interior do estado do Rio Grande do Sul, com o
propósito de quantificar um investimento desse tipo e os motivos pelos quais o
gerenciamento de estoques envolvendo informatização, em indústrias metalúrgicas
de pequeno porte, não tem obtido resultados positivos. Através dos pontos
negativos, desenvolveu-se o escopo para realizar um replanejamento e,
posteriormente, analisou-se mais uma vez a situação. Hoje, já são percebidos
resultados satisfatórios, conforme será demonstrado.
