Exploring the Future of Urban Development in the Region of Stockholm : Promotion of adolescent’s mental health and well-being through experimental governance

Perinajova, Barbora January 2023 (has links)
This thesis will explore the possible obstacles among Region Stockholm municipalities in promoting adolescents’ mental health and well-being through experimental governance. The thesis will examine the municipal and non-municipal points of view on specifically promoting adolescents’ mental health and well-being through experimental governance in the Swedish context with the use of urban sustainability transitions and transition management frameworks. The urban sustainability transitions will help us understand the role of cities in creating new modes of urban governing processes. In addition, the use of a transition management framework will help us to understand the importance of shifting from traditional management approaches by rather placing greater focus on innovative and design-oriented methods. This approach highlights the importance of learning by doing process rather than a reaching specific destination. In addition, I will use a qualitative research design that uses the methods of semi- structured interviews. The empirical findings are analysed with the help of thematic analysis through the theoretical frameworks and concepts. It has been demonstrated an observable slow- paced adoption of experimental governance, insufficient specific promotion of adolescents’ mental health and well-being, and distant relationship between experimental governance and promotion specifically adolescents’ mental health and well-being in the urban planning process.

Open Innovation Strategies : A new pivot for OEM and Start-up Coopetition

Sénécal, Julia, Jallow, Ismaila A. January 2019 (has links)
“[A]s much as any other product, the car has shaped not only the global economy but how billions of people live”1,whilethe digital area is nowshapingthe car.Coopetition, a strategy presenting firms with the opportunity to collaborate and compete at the same time,is becoming a prevalent phenomenonamong large OEMs and start-ups in the automotive industry.Respectively, considering that coopetition, in the context of open innovation and new technologies, has been identified as a successful strategy, this thesis will therefore analyse the relationship between OEMs and external start-ups in the context of coopetition and corporate open innovation strategies. Several typesof corporate incubators, accelerators and corporate innovation labs emerged within the last years, howeveran integration of all three of these has not yet been widely explored. Accordingly, while these open innovation streamsare used by large corporationsto get access to the start-upecosystemand increase their innovation capabilities, the relationship between OEMs and external start-ups will further lead to CIIAs (a combined approach of corporate incubators, corporate innovation labs and corporate accelerators),demonstratedin the context of coopetition. This exploratory study therebycontributes to the relationship between external start-ups and OEMsthrough aCIIA approach,answering the two following researchquestions;•What are the main drivers of the OEM and external start-uprelationship?•How do OEMs and external start-ups coopete in the context of corporate open innovation strategies?To dulyanswer these research questions, we choseaqualitative researchmethodcombined with an interpretivist and inductiveapproachas well asempirical findings generated from 6semi-structured interviews. We furthercontributed tothe illustrationof the key aspects of CIIAsas well asthe motives, management and implications behind the relationshipsbetween OEMs and external start-upsbyaconceptual framework. Our analysishence showsthe significanceof the access to complementary resources, the co-creation and co-development of value as well as the systematic implementation of a proof of conceptin the light of thesecoopetitive relationshipsbetween CIIAs and external start-ups.However, consideringthat thisresearch has been based on the German automotive industry only, it will require further research in other contexts, sectors or countries. To conclude, thisthesis contributes tothe management literature ofcoopetition, corporate innovation and entrepreneurship. We proposeda finalframeworkto highlightthekey motives, the management and the implications behind thecoopetitive relationshipsbetween OEMsand external start-upsthrough the CIIA platform.This willexpectedly help managers and entrepreneurs develop efficientmanagement techniques as well asfurther recognize and understand the influential dynamicspresent in these relationships

Enriching Remote Labs with Computer Vision and Drones / Enrichir les laboratoires distants grâce à la vision par ordinateur avec drone.

Khattar, Fawzi 13 December 2018 (has links)
Avec le progrès technologique, de nouvelles technologies sont en cours de développement afin de contribuer à une meilleure expérience dans le domaine de l’éducation. En particulier, les laboratoires distants constituent un moyen intéressant et pratique qui peut motiver les étudiants à apprendre. L'étudiant peut à tout moment, et de n'importe quel endroit, accéder au laboratoire distant et faire son TP (travail pratique). Malgré les nombreux avantages, les technologies à distance dans l’éducation créent une distance entre l’étudiant et l’enseignant. Les élèves peuvent avoir des difficultés à faire le TP si aucune intervention appropriée ne peut être prise pour les aider. Dans cette thèse, nous visons à enrichir un laboratoire électronique distant conçu pour les étudiants en ingénierie et appelé «LaboREM» (pour remote laboratory) de deux manières: tout d'abord, nous permettons à l'étudiant d'envoyer des commandes de haut niveau à un mini-drone disponible dans le laboratoire distant. L'objectif est d'examiner les faces-avant des instruments de mesure électroniques, à l'aide de la caméra intégrée au drone. De plus, nous autorisons la communication élève-enseignant à distance à l'aide du drone, au cas où un enseignant serait présent dans le laboratoire distant. Enfin, le drone doit revenir pour atterrir sur la plate-forme de recharge automatique des batteries, quand la mission est terminée. Nous proposons aussi un système automatique pour estimer l'état de l'étudiant (frustré / concentré..) afin de prendre les interventions appropriées pour assurer un bon déroulement du TP distant. Par exemple, si l'élève a des difficultés majeures, nous pouvons lui donner des indications ou réduire le niveau de difficulté de l’exercice. Nous proposons de faire cela en utilisant des signes visuels (estimation de la pose de la tête et analyse de l'expression faciale). De nombreuses évidences sur l'état de l'étudiant peuvent être acquises, mais elles sont incomplètes, parfois inexactes et ne couvrent pas tous les aspects de l'état de l'étudiant. C'est pourquoi nous proposons dans cette thèse de fusionner les preuves en utilisant la théorie de Dempster-Shafer qui permet la fusion de preuves incomplètes. / With the technological advance, new learning technologies are being developed in order to contribute to better learning experience. In particular, remote labs constitute an interesting and a practical way that can motivate nowadays students to learn. The student can at any time, and from anywhere, access the remote lab and do his lab-work. Despite many advantages, remote technologies in education create a distance between the student and the teacher. Without the presence of a teacher, students can have difficulties, if no appropriate interventions can be taken to help them. In this thesis, we aim to enrich an existing remote electronic lab made for engineering students called “LaboREM” (for remote Laboratory) in two ways: first we enable the student to send high level commands to a mini-drone available in the remote lab facility. The objective is to examine the front panels of electronic measurement instruments, by the camera embedded on the drone. Furthermore, we allow remote student-teacher communication using the drone, in case there is a teacher present in the remote lab facility. Finally, the drone has to go back home when the mission is over to land on a platform for automatic recharge of the batteries. Second, we propose an automatic system that estimates the affective state of the student (frustrated/ confused/ flow..) in order to take appropriate interventions to ensure good learning outcomes. For example, if the student is having major difficulties we can try to give him hints or reduce the difficulty level. We propose to do this by using visual cues (head pose estimation and facial expression analysis). Many evidences on the state of the student can be acquired, however these evidences are incomplete, sometimes inaccurate, and do not cover all the aspects of the state of the student alone. This is why we propose to fuse evidences using the theory of Dempster-Shafer that allows the fusion of incomplete evidence.

No. of bitstreams: 1 Lauren Homrich Aita_.pdf: 3238471 bytes, checksum: bcfd6d5d4a3a884ab5d3c5fa2d58a08d (MD5) Previous issue date: 2016-03-29 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / UNISINOS - Universidade do Vale do Rio dos Sinos / Esta dissertação tem como tema a Inovação Social em Living Labs, deflagrada na interface entre a constituição de novas sociabilidades e os modos de produção de valor a partir de contribuições do Design Estratégico. A discussão das práticas projetuais foi feita à luz dos conceitos ecossistêmicos da sociedade em rede e do metaprojeto como cultura de projeto. Além da revisão bibliográfica, também foi realizada uma pesquisa aplicada de inspiração etnográfica, com abordagem qualitativa e com objetivo exploratório junto a dois Living Labs: o TransLAB e o Laboratório Mercur de Inovação Social. Como resultado, foram apresentados fatores de mobilização em redes de projeto para Inovação Social, assim como foram descritas estratégias e instrumentos projetuais utilizados para promoção de trabalho colaborativo. Em ambos contextos pesquisados, o Living Lab pôde ser compreendido como um Espaço Hub que habilita a articulação de redes projetuais que buscam gerar sistemas-produto-serviço socialmente inovadores ou novos modelos de negócio. À luz do Design Estratégico, a pesquisa também identificou a potencialidade de Living Labs serem apropriados como Cenários Vivos, em que se cria um deslocamento para ampliar possibilidades criativas e as pessoas experimentam outras lógicas organizacionais, provocando reflexões e ativando sua ação estratégica para uma transição sustentável com a criação de novos modos de relação e de coprodução de valor. Por fim, foram indicadas diretrizes para promoção de processos inclusivos na articulação de redes projetuais para a Inovação Social no contexto de Living Labs. / This dissertation is subject to Social Innovation in Living Labs, triggered at the interface between the creation of new sociability and value of production methods from contributions of Strategic Design. The discussion of projective practices was made in light of ecosystem concepts of network society and the meta-project and project culture. Besides the theory review was also conducted an ethnographic inspiration applied research with a qualitative approach and exploratory objective within two Living Labs: the TransLAB and Mercur Laboratory of Social Innovation. As a result, mobilization factors in network design for social innovation were presented, as strategies and projective instruments used for collaborative work promotion were described. In both contexts studied, the Living Lab could be understood as a Hub Space that enables the articulation of projective networks that seek to generate socially innovative product-service-systems or new business models. In the light of the Strategic Design, the survey also identified the Living Labs capability to be recognized as Living Scenarios in which is possible to create an offset to expand creative possibilities, and people experience other organizational logics, causing reflections and activating its strategic action for a transition sustainable with the creation of new relations and co-production value. Finally, guidelines were recommended for promotion of inclusive processes in the articulation of projective networks for Social Innovation in the context of Living Labs.

Iterative joint detection and decoding of LDPC-Coded V-BLAST systems

Tsai, Meng-Ying (Brady) 10 July 2008 (has links)
Soft iterative detection and decoding techniques have been shown to be able to achieve near-capacity performance in multiple-antenna systems. To obtain the optimal soft information by marginalization over the entire observation space is intractable; and the current literature is unable to guide us towards the best way to obtain the suboptimal soft information. In this thesis, several existing soft-input soft-output (SISO) detectors, including minimum mean-square error-successive interference cancellation (MMSE-SIC), list sphere decoding (LSD), and Fincke-Pohst maximum-a-posteriori (FPMAP), are examined. Prior research has demonstrated that LSD and FPMAP outperform soft-equalization methods (i.e., MMSE-SIC); however, it is unclear which of the two scheme is superior in terms of performance-complexity trade-off. A comparison is conducted to resolve the matter. In addition, an improved scheme is proposed to modify LSD and FPMAP, providing error performance improvement and a reduction in computational complexity simultaneously. Although list-type detectors such as LSD and FPMAP provide outstanding error performance, issues such as the optimal initial sphere radius, optimal radius update strategy, and their highly variable computational complexity are still unresolved. A new detection scheme is proposed to address the above issues with fixed detection complexity, making the scheme suitable for practical implementation. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2008-07-08 19:29:17.66

Microfluidique supercritique pour la compréhension des systèmes CO2 / eau sous pression et en température : Application à la gestion durable de la filière CO2 / Supercritical Microfluidics for understanding CO2 / water systems under pressure and temperature : Application to the sustainable management of the anthropogenic CO2

Liu, Na 22 November 2013 (has links)
Le stockage géologique du CO2 est une stratégie prometteuse pour limiter la concentration de CO2anthropique dans l’atmosphère. Les aquifères salins (AS) ont été identifiés comme des optionsviables car ils possèdent de grandes capacités potentielles de stockage. Toutefois, les processusrelatifs au piégeage du CO2 souffrent d’un manque de connaissances fondamentales car il existe peude méthodes d’expérimentation rapides et reproductibles, travaillant dans les conditions du stockagegéologique. Ainsi, nous avons développé des microréacteurs haute pression, véritables laboratoiresgéologiques sur puce (GLoCs), recréant les conditions de porosité et de perméabilité des AS pour :(i) Mesurer la solubilité du CO2 dans l’eau et les saumures via un couplage microsystèmes /spectroscopie Raman ;(ii) Etudier les mécanismes d’invasion du CO2 dans les formations géologiques, incluantnotamment les écoulements diphasiques en milieux poreux, les séparations de phases etla précipitation des carbonates. / CO2 geological storage is a promising strategy to control the anthropogenic CO2 concentration in theatmosphere. Deep saline aquifers (DSA) were identified as viable options since they exhibit largestorage capacity. However, processes inherent to CO2 trapping suffer from a lack of fundamentalknowledge, since there are too few fast and reproducible experimental approaches able to work atgeological storage conditions. Therefore, to address these limitations, we have developed highpressure microreactors, so-called “geological labs on a chip” - GloCs – allowing mimicking porosityand permeability conditions of DSA for:(i) Measuring solubility of CO2 in water and brine through the combination of microsystemsand confocal Raman spectroscopy,(ii) Studying invasion mechanisms of CO2 in geological formations, including in particularbiphasic flows in porous media, phase separation and carbonates precipitation.

Applications des laboratoires géologiques sur puce pour les problématiques du stockage du CO2 / Applications of geological labs onf chip for CO2 storage issues

Morais, Sandy 19 December 2016 (has links)
Le stockage géologique du CO2 dans les aquifères salins représente une stratégie prometteuse pour la réduction des émissions de CO2 anthropiques. Ce type de stockage requiert des connaissances fondamentales afin d'évaluer les scénarios d'injection, d'estimer la capacité des réservoirs et les risques de fuite. C'est dans ce contexte que des outils microfluidiques haute pression/haute température ont été développés afin d'étudier différents mécanismes liés aux technologies de stockage de CO2. Les laboratoires géologiques sur puce (GLoCs) permettent de mener des expériences à des conditions de pression et de température typiques des réservoirs (25 < T < 50°C, 50 < p < 10 MPa) et d'en mimer des propriétés géologiques.Ce manuscrit présente dans un premier temps les stratégies de fabrication des GLoCs et l'accès à leurs caractéristiques (porosité et perméabilité). La détection du CO2 directement au sein de GLoCs grâce à l'implémentation de fibres optiques par spectroscopie infrarouge est ensuite présentée, ainsi que la mise en œuvre de la technique de laminographie X menées à l'ESRF pour le suivi de dissolution de carbonates dans des microcanaux. Le manuscrit explicite ensuite les investigations, menées avec des GLoCs concernant les différents mécanismes de piégeage du CO2 à l'échelle du pore. La visualisation directe et le traitement d'image ont permis de suivre l'évolution des phases de CO2 et des phases aqueuses au sein du GLoC et les mécanismes de déplacement et de saturation. Enfin, les travaux en cours sont exposés, comme les expériences de drainage avec des saumures réactives ou la formation d'hydrates au sein de milieux poreux. / CO2 geological storage in deep saline aquifers represents a mediation solution for reducing the anthropogenic CO2 emissions. Consequently, this kind of storage requires adequate scientific knowledge to evaluate injection scenarios, estimate reservoir capacity and assess leakage risks. In this context, we have developed and used high pressure/high temperature microfluidic tools to investigate the different mechanisms associated with CO2 geological storage in deep saline aquifers. The silicon-Pyrex 2D porous networks (Geological Labs On Chips) can replicate the reservoir p,T conditions (25 < T < 50°C, 50 < p < 10 MPa), geological and topological properties. This thesis manuscript first highlights the strategies developed during this work to fabricate the GLoCs and to access to global characteristics of our porous media such as porosity and permeability, which are later compared to numerical modelling results. The carbon dioxide detection in GLoCs mimicking p,T conditions of geological reservoirs by using the direct integration of optical fiber for IR spectroscopy is presented. I then detail the strategies for following the dissolution of carbonates in GLoCs with X-rays laminography experiments.Then, the manuscript focuses on the use of GLoCs to investigate each CO2 trapping mechanism at the pore scale. The direct optical visualization and image processing allow us to follow the evolution of the injected CO2/aqueous phase within the reservoir, including displacement mechanisms and pore saturation levels.Eventually, I present the ongoing works such as experiments with reactive brines and hydrates formations in porous media.

Caracterização e manejo de resíduos gerados nos laboratórios do Instituto de Biologia da Universidade do Estado do Rio de Janeiro, IBRAG, UERJ. / Characterization and management of waste generated in laboratories Institute of Biology of the University of Rio de Janeiro State, IBRAG, UERJ.

Anselma Lucia Novo Reis 27 March 2009 (has links)
Fundação Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio de Janeiro / O crescimento da população mundial, aumento da industrialização e consumo de bens e serviços, tem aumentado significativamente a geração de resíduos que vem causando impactos negativos na saúde humana e ambiental. Neste contexto, se destaca a geração de produtos perigosos, tais como, os resíduos de serviços de saúde- RSS. Por apresentarem riscos à saúde da população e do meio ambiente, recomendações, normas e legislações surgiram para orientar a melhor maneira o manejo e disposição final destes resíduos. No Brasil, as resoluções NBR 306/04 e CONAMA 358/05 dão diretrizes para a elaboração de um Plano de Gerenciamento de Resíduos de Serviços de Saúde-PGRSS. Os laboratórios de pesquisa e ensino, como geradores de RSS, precisam se adequar à legislação, porém existem poucos estudos e a legislação não aborda especificamente os resíduos destes laboratórios. Os laboratórios e unidades da UERJ, geradores de RSS, não possuem PGRSS. Na UERJ, somente dois estudos levantaram os resíduos gerados em laboratórios, entretanto os dados levantados para o Instituto de Biologia são incompletos. Este estudo buscou avaliar o manejo dos resíduos biológico, químico, radioativo e perfurocortante nos laboratórios do Instituto de Biologia. Os dados foram coletados pelas informações dadas pelos professores, funcionários ou alunos dos laboratórios e por observação direta. Os dados de manejo foram analisados de acordo com a RDC 306/04 Anvisa, da Resolução CONAMA 358/05 e das fichas de segurança dos produtos químicos. Foram estudados 83% dos laboratórios do Instituto de Biologia. Destes, 43% geram resíduos químicos. Dos laboratórios caracterizados, 19 laboratórios geram somente resíduo químico. No pavilhão Américo Piquet estão localizados 63% dos laboratórios geradores de resíduos biológicos, químicos, perfurocortantes ou radioativos. Do total de resíduos gerados nos laboratórios, cerca de 80% foi de resíduo biológico, 15% de resíduo químico e 5% de resíduo perfurocortante. O manejo dos resíduos nos laboratórios é realizado de maneira confusa, geralmente os erros estão na segregação, identificação e acondicionamento. De maneira geral, as informações sobre o manejo utilizado para os resíduos são incompletas, desconhecidas ou imprecisas. As ações incorretas do manejo de resíduos são características para cada tipo de resíduo; no resíduo biológico, freqüentemente, encontraram-se resíduos comuns. O resíduo químico é geralmente descartado sem tratamento prévio na rede de esgoto. O resíduo radioativo não possui identificação e acompanhamento do decaimento, para posterior descarte. No resíduo perfurocortante encontrou-se, freqüentemente, resíduo biológico e químico misturados. Para o sucesso de um futuro Plano de Gerenciamento de Resíduos, a capacitação dos profissionais é muito importante. A Instituição deve investir na consolidação desse trabalho, considerando que ela não pode se furtar de adotar uma postura pró-ativa com relação aos problemas ambientais, sejam eles dirigentes da instituição, ou profissionais que ali atuam. Espera-se que essa pesquisa possa auxiliar neste sentido. / The growth of world population, industrialization and increasing consumption of products and services, has significantly increased the generation of waste which is causing negative impacts on human health and environment. In this context, it emphasizes the generation of hazardous products such as hospital waste. For their risks to public health and the environment, recommendations, standards and laws have emerged to guide the way the management and final disposal of wastes. In Brazil, the resolutions NBR 306/04 e CONAMA 358/05 provide guidelines for the preparation of a Plan of Waste Management of Health Services. The research and education laboratories must adapt to law, but there are few studies and the legislation does not specifically address the waste of these laboratories. The UERJ laboratories not have PGRSS. In UERJ, only two studies have raised the waste generated in laboratories, but the data collected for Institute of Biology -IBRAG- are not complete. Thus this study raised the types and quantities of waste generated biological, chemical, radioactive and perforating, and assessed the management of these laboratories in Ibrag. Data were collected by the information given by teachers or students or employees of laboratories and by direct observation. The data management were analyzed according to the RDC 306/04 Anvisa of Resolution CONAMA 358/05 and safety data sheets chemical elements. We studied 83% of laboratories IBRAG/UERJ. Of these, 43% generate chemical waste. Characterized laboratories, 19 laboratories only generate chemical waste. PAPC flags are located in 63% of laboratories generators of waste biological, chemical, radioactive or perforating. Of total waste generated in laboratories, approximately 80% was organic waste, 15% of chemical waste and 5% waste perforating. The management of waste in the laboratories is performed so confusing, usually the errors are in segregation, identification and packaging. In general, information on any used for waste management are incomplete, inaccurate or unknown. Shares of incorrect handling of waste are characteristic for each type of waste, the organic residue, often found themselves ordinary waste, or discarded in the collector is made of waste or waste organic perforating treaty should now be discarded as common waste. The chemical residue usually discarded without prior treatment in the sewage network. The radioactive waste without identification and monitoring of decay for later disposal. No residue was found perforating often, biological and chemical residue. For the success of a future Plan of Waste Management, the training of professionals is very important. The institution should invest in the consolidation of this work, considering she can not escape to take a pro-active with respect to environmental problems, be they leaders of the institution, or professionals who work there. It is hoped that this research can help in this direction.
