Génération d'explications pour la gestion énergétique dans les bâtiments / Generation of explanations for energy management in buildings

Alzouhri alyafi, Amr 27 May 2019 (has links)
L'énergie est fondamentale pour maintenir le confort et façonne notre vie moderne. Avec la demande excédentaire en énergie, les systèmes de gestion de l’énergie résidentielle apparaissent avec le temps. Ils visent à réduire ou moduler la consommation d’énergie tout en maintenant un niveau de confort acceptable. Des systèmes efficaces de gestion de l'énergie domestique devraient intégrer une représentation comportementale d'un système domestique, y compris les habitants. Il établit des relations entre différentes variables environnementales et des phénomènes hétérogènes présents dans une maison. Par conséquent, ces systèmes sont complexes à construire et à comprendre pour les habitants. Pour cette raison, les concepteurs ont essayé d'automatiser autant que possible les systèmes de CVC, les éclairages ... afin de promouvoir le concept de "faire à la place". Cela était justifié car il était presque impossible d'impliquer les occupants et de créer une relation entre les occupants et les systèmes énergétiques. Ce concept crée différents problèmes car les occupants sont détachés du système énergétique et ne comprennent pas ses fonctionnalités ni son fonctionnement.Pour surmonter cette difficulté, ce travail met en avant le concept de "faire avec" en essayant d'impliquer l'occupant dans la boucle avec son système de gestion de l'énergie. C'est là que l'explication est nécessaire pour permettre aux occupants de découvrir les connaissances du système énergétique et de développer leur capacité à comprendre comment le système fonctionne et pourquoi il recommande différentes actions. L'explication est le moyen de découvrir de nouvelles connaissances et, par conséquent, d'impliquer les occupants. Pour les humains, l'explication joue un rôle important dans la vie. C'est l'un des principaux outils d'apprentissage et de compréhension. Il est même utilisé dans la communication et les aspects sociaux. Les gens ont tendance à l'utiliser en plus d'apprendre à montrer leurs connaissances sur un sujet pour gagner la confiance des autres ou pour clarifier une situation. Mais générer des explications n’est pas une tâche facile. C'est l'un des problèmes scientifiques récurrents de plusieurs décennies. Les explications ont de nombreuses formes, types et niveaux de clarté. Cette étude se concentre sur les explications causales. Comme il s’agit de la forme d’explication la plus intuitive à comprendre par les occupants, elle est conçue pour transférer les connaissances issues de systèmes complexes tels que les modèles énergétiques. Le défi scientifique est de savoir comment construire des explications de causalité pour les habitants à partir d’un flux de données de capteurs observées. / Energy is fundamental to maintain comfort and it shapes our modern life. With the excess demand for energy, home energy management systems are appearing with time. They aim at reducing or modulating energy consumption while keeping an acceptable level of comfort. Efficient home energy management systems should embed a behavioral representation of a home system, including inhabitants. It establishes relationships between different environmental variables and heterogeneous phenomena present in a home. Therefore, those systems are complex to build and to understand for inhabitants. For this reason, the designers did try to automatize as much as possible the HVAC systems, the lightings ... so they promoted the concept of “doing instead”. This was justified as it was nearly impossible to implicate occupants and to create a relation between occupants and energy systems. This concept does create different problems as occupants are detached from the energy system and they don’t understand its functionality nor how it is working.To overcome this difficulty this work promotes the concept of “doing with” as it tries to implicate the occupant in the loop with their energy management system. This is where the explanation is needed to allow occupants to discover the knowledge in the energy system and to develop their capacity of understanding how the system is working and why it is recommending different actions. The explanation is the way to discover new knowledge and consequently, to involve occupants. For humans, explanation plays an important role in life. It is one of the main tools for learning and understanding. It is even used in communication and social aspects. People tend to use it besides learning to show their knowledge about a subject to gain the confidence of others or to clarify a situation. But generating explanations is not an easy task. It is one of the ongoing scientific problems from several decades. Explanations have numerous forms, types, and level of clearness. This study is focusing on the causal explanations. As it is the most intuitive form of explanation to be understood by occupants and is adapted to transfer the knowledge from complex systems like energy models. The scientific challenge is how to construct causal explanations for the inhabitants from a flow of observed sensor data.

The design and application of wayfinding in physically and virtual immersive environnments

Haarhoff, Chané January 2016 (has links)
Thesis (M.A. (Interactive Digital Media))--University of the Witwatersrand, Faculty of Humanities, 2016. / The focus of this research paper is on the relationship between wayfinding and interactive, immersive environments. Wayfinding systems inherently exist to assist people on a journey to a desired destination. Interactive immersive environments have introduced a new paradigm, in which users are becoming active participants within both physical and virtual environments. The merging of wayfinding with immersive environments could thus present potential to propel wayfinding to a new level. The effectiveness and applications of wayfinding systems within three immersive environments is therefore determined by looking at the design of informational wayfinding, the ease of navigability within immersive environments and the adaptation and use of wayfinding techniques within four case studies. The three immersive environments chosen to be examined within this paper are: physically immersive environments, digital physically immersive environments and virtual immersive environments. These environments are represented by four case studies which include Menlyn Park Shopping Centre's newly updated wayfinding system, Find Your Way Essex, a virtual wayfinding mobile application, StreetMuseum: Museum of London a purely digital mobile application and Honeywell - Virtual Museum Tour, a virtual wayfinding experience that relies fully on the GoogleCardboard device. / GR2017

O comprometimento como estratégia para a adoção de um sistema de gestão ambiental: O caso de uma instituição pública de pesquisa. / Commitment as a strategy for the adoption of an environmental management system: The case of a public research institution

Silva, Maria Cecilia Cavalcante da 23 February 2017 (has links)
Esta tese, utilizando-se do mapa cognitivo Strategic Options Development and Analysis - SODA, se propôs a atender o objetivo nela especificado, ou seja, avaliar a importância do comprometimento organizacional para a implementação de um Sistema de Gestão Ambiental SGA por parte dos quinze Gerentes de uma Instituição Pública Federal, localizada no estado de São Paulo. Os dados que compuserem o mapa cognitivo, foram obtidos por meio de entrevista face a face, no período de maio a novembro de 2015, e de reuniões grupais com os referidos Gerentes, no período de dezembro de 2015 a março de 2016. A utilização do método de estruturação de problemas - Problem Structuring Methods (PSMs) - mapa cognitivo - SODA possibilitou investigar, as possíveis incertezas, complexidades e conflitos, voltados para o elemento comprometimento, provenientes da adoção de uma gestão ambiental, por intermédio da implementação de um Sistema de Gestão Ambiental SGA. O resultado da análise do mapa cognitivo demonstrou a importância do comprometimento organizacional quando da intenção de se adotar um Sistema de Gestão Ambiental. Diferentemente do entendimento de Barbieri (2007), o presente estudo coloca a importância desse comportamento não somente por parte da alta direção, mas também por parte de toda a equipe a ser envolvida nas atividades concernentes a tal sistema. Permitiu também a construção de um modelo de mensuração do comprometimento em relação ao Sistema de Gestão Ambiental SGA. O comprometimento mensurado por meio de referido instrumento, está dividido em dois componentes: afetivo que tem o comprometimento como um apego, como um envolvimento, onde ocorre a identificação com a empresa, funcionários com forte comprometimento afetivo permanecem na empresa porque querem, e normativo o comprometimento como uma obrigação em permanecer na organização, funcionários identificados com esse comportamento permanecem na empresa porque sentem que tem essa obrigação. O modelo de mensuração do comprometimento neste estudo sugerido, a ser validado em estudos longitudinais, permitirá mapear elementos de forma que possam observar tendências. Referido instrumento não foi validado neste estudo, no entanto sugere-se que estudos futuros, por meio de estudos longitudinais procedam sua validação. / This thesis, using the Cognitive Map Strategic Options Development and Analysis (SODA), is proposed to meet the objective specified therein, i.e. to evaluate the importance of the organizational commitment to the implementation of an Environmental Management System (SGA), by the fifteen Managers of a Federal Public Institution, located in the state of São Paulo. The data composing the cognitive map were obtained through a face-to-face interview, from May to November 2015, and group meetings with the aforementioned managers from December 2015 to March 2016. The use of the Problem Structuring Methods (PSMs) SODA cognitive map made it feasible to investigate possible uncertainties, complexities and conflicts, related to the commitment element, from the adoption of the environmental management through the implementation of An Environmental Management System EMS. The results of the cognitive map analysis showed the importance of the organizational commitment, when an Environmental Management System is intended to be adopted. Differently from Barbieri\'s (2007) understanding, the present study places the importance of this behavior, not only by the top management, but also by the whole team to be involved in the activities related to such a system. It, also, allowed the construction of a commitment measurement model in relation to the Environmental Management System - EMS. The commitment measured by this instrument is divided into two components: affective, which has the commitment as an attachment and, even, involvement, where the identification with the company occurs: employees with strong affective commitment remain in the company because they want it and, also, as normative involvement. The commitment is felt as an obligation to remain in the organization: employees identified with this behavior remain in the company because they feel they should do it. The model of commitment measurement in this suggested survey, to be validated in longitudinal studies, will allow elements to be mapped so that trends may be observed. The mentioned instrument was not validated in this study, however, it is suggested that future research, through longitudinal studies, would do it.

Transformando textos em mapas cognitivos: desenvolvimento e um exemplo de aplicação / Transforming texts in cognitive maps: development and an application example

Junqueira, Marianna Meirelles 14 June 2013 (has links)
O principal objetivo dessa pesquisa consistiu em desenvolver e analisar uma ferramenta de transformação de textos escritos por estudantes em mapas cognitivos para fornecer de forma visual, global e sintética, uma visão das principais relações conceituais citadas em um conjunto de textos. A ferramenta foi estruturada em dois momentos: primeiramente os textos foram lidos para a geração de uma matriz de associação que representa as relações encontradas entre cada par de conceitos. Em seguida, as matrizes foram somadas e, a partir da matriz final, foram construídos diferentes tipos de mapas cognitivos. Para o desenvolvimento de tal ferramenta, foram coletados dados na disciplina Introdução ao Ensino de Química do curso de licenciatura em química do IQ-USP. Essa disciplina foi organizada em três módulos denominados: natureza da ciência, concepções de ensino e aprendizagem, e natureza do conhecimento químico e a aprendizagem da química. No final de cada módulo, foi aplicada uma questão dissertativa com uma lista de conceitos pré-selecionados que objetivava conhecer as relações conceituais expressas pelos estudantes sobre o tema em questão. A partir das respostas dos alunos foram realizados alguns testes: (i) com o software ALA-Reader® e os seus modos de leitura L e S para a quantificação das relações entre conceitos presentes nos textos e geração da matriz de associação; (ii) para verificação da influência da natureza dos textos na contabilização das relações entre conceitos e na elaboração dos mapas e (iii) para a obtenção das representações gráficas do tipo vizinho(s) mais próximo(s) e corte percentual representativo. A partir dos testes realizados, foi possível concluir que o modo de leitura S do programa ALA-Reader® é mais coerente e deve ser utilizado para a leitura dos textos. Além disso, a matriz de associação gerada depende essencialmente da estrutura do texto em questão - texto original ou texto modificado para proposições, tendo em vista a diferença na contabilização das relações par a par encontradas nos textos. Os dois tipos de redes de conceitos apresentam diferentes focos, porém, podem ser considerados complementares. As redes vizinho(s) mais próximo(s) se mostraram interessantes para análises que requerem todos os conceitos fornecidos ou almejam buscar as relações feitas por determinados conceitos. As redes com corte percentual representativo apresentaram-se auxiliares para investigações que requeiram fazer um recorte nos pontos considerados principais pelos sujeitos. No discorrer do texto, também são apresentados alguns recursos que podem ser acrescidos nas redes de conceitos para auxiliar as análises, como a inserção das frases de ligação gerando um mapa conceitual ou o destaque dos conceitos centrais nas estruturas. Com o objetivo de ilustrar o uso das representações gráficas construídas, foi feita uma breve interpretação dessas no contexto da disciplina na qual os dados foram coletados. A partir dessa análise, foi possível, por exemplo, elencar as principais ideias explicitadas pelos alunos e relacioná-las ao que foi discutido em sala de aula. / The main objective of this research was to develop and analyze a tool to turn texts written by students into cognitive maps to provide a visual, global and synthetic representation of the key conceptual relationships mentioned in a set of texts. The tool was structured in two phases: first the texts were read to generate a proximity file representing the relationships found between each pair of concepts. Then, the proximity files were added and from the final file different types of cognitive maps were built. For the development of this tool, data were collected in the academic discipline entitled Introduction to Teaching Chemistry, for the degree in Chemistry at IQ-USP. This academic discipline was organized in three modules called: nature of science, conceptions of teaching and learning, and the nature of chemical knowledge and Chemistry learning. At the end of each module, an essay question was applied with a list of pre-selected concepts that aimed to investigate the conceptual relations established by the students on the topic in question. From students\' responses some tests were performed: (i) with the ALA-Reader® software and its reading modes L and S to quantify the relationships between concepts present in texts and generate the proximity file, (ii) to verify the influence of the nature of the texts in the accounting of the relationships between concepts and in the elaboration of maps, and (iii) to obtain graphical representations of close neighbors type and representative percentage cut. Based on the tests, it was concluded that the mode S of reading of the ALA Reader® program is more consistent and should be used for the reading of the texts. Furthermore, the proximity file generated depends essentially on the structure of the text in question - the original text or the modified one for propositions, in view of the difference in the accounting of conceptual relations found in the texts. The two types of networks of concepts have different focuses, however, they can be considered complementary. The close neighbors networks were interesting for analysis which require all concepts provided or aim to seek relations established by certain concepts. Networks with representative percentage cut proved to be auxiliary for those investigations which require a cut in the main points considered by the subjects. Throughout the text, some features that can be added to the networks to support the analysis are also presented, such as: the insertion of linking phrases generating a concept map or the highlight of the central concepts in the structures. In order to illustrate the use of graphical representations built, a brief interpretation of them was made based on the context of the academic discipline in which the data were collected. This study enabled, for example, the development of a list the main ideas conveyed by students and the possibility to relate them to what was discussed in class

Developing a Mixed-Methods Method to Model Elderly Health Technology Adoption with Fuzzy Cognitive Map, and its Application in Adoption of Remote Health Monitoring Technologies by Elderly Women

Rahimi, Noshad 03 August 2018 (has links)
Providing healthcare to the ever-rising elderly population has become a severe challenge and a top priority. Emerging innovations in healthcare, such as remote health monitoring technologies, promise to provide a better quality of care and reduce the cost of healthcare. However, many elderly people reject healthcare innovations. This lack of adoption constitutes a big practical problem because it keeps the elderly from benefiting from technology advances. The phenomenon is even more pronounced among elderly women, who represent the majority of the elderly population. A plethora of studies in the field of technology adoption resulted in sound, but highly generalized theories that are too parsimonious to provide practical insight into the phenomenon of elderly healthcare technology adoption (EHTA). There is a call to arms for novel approaches that facilitate the creation of models that expand technology adoption theories to the specifics of EHTA. This dissertation is a response to this call to arms, and it contributes to modeling practice in the EHTA field. It uses fuzzy cognitive mapping to design a novel mixed-methods modeling approach. Since elderly women constitute the majority of the elderly population, this dissertation treats elderly women's health technology adoption (EWHTA) as the case-in-point.

Negotiating the landscape : a comparative investigation of wayfinding, mapmaking and territoriality in selected hunter-gatherer societies

Wylie, Joanna Kate, n/a January 2004 (has links)
As human beings we are continually interacting with the landscape, and have been doing so throughout the entire course of our evolution. This thesis specifically investigates the way in which hunter-gatherers negotiate and interact with their landscapes, focusing on three patterns of behaviour: wayfinding, mapmaking and territoriality. An examination of the relevant international literature reveals that globally, hunter-gatherer groups both past and present share a number of similarities with regard to their wayfinding and mapmaking techniques, territorial behaviour. A case study of Maori interaction with the landscape of prehistoric and protohistoric Te Wai Pounamu [the South Island] provides further support for the central argument that hunter-gatherers collectively negotiate and interact with the landscape in distinctive ways. This is contrasted with the interaction of European explorers and travellers with the 19th century landscape of Te Wai Pounamu in Chapter 5. It is determined that hunter-gatherers use detailed cognitive or 'mental' maps to navigate their way through a range of landscape from dense forests to barren plains. These maps often consist of sequences of place names that represent trails. These cognitive maps are most commonly developed through direct interaction with the landscape, but can also be formed vicariously through ephemeral maps drawn with the purpose of communicating geographical knowledge. Prior to European contact, little importance seems to have been given to artefactual or 'permanent' maps within hunter-gatherer societies as the process of mapmaking was generally regarded as more significant than the actual product. Although the literature on hunter-gatherer territoriality is complex and in some cases conflicting, it is contended that among a number of hunter-gatherer groups, including prehistoric and protohistoric Maori in Te Wai Pounamu, interaction and negotiation with the landscape was/is not restricted to exclusive territories marked by rigidly defined boundaries. Among these groups, a specific method of territoriality known as 'social boundry defence' was/is employed. This involves controlling access to the social group inhabiting an area rather than access to the area itself, as with groups utilising the territorial method of 'perimeter defence'.
