Video object segmentation using phase-base detection of moving object boundariesTo, Thang Long, Information Technology & Electrical Engineering, Australian Defence Force Academy, UNSW January 2005 (has links)
A video sequence often contains a number of objects. For each object, the motion of its projection on the video frames is affected by its movement in 3-D space, as well as the movement of the camera. Video object segmentation refers to the task of delineating and distinguishing different objects that exist in a series of video frames. Segmentation of moving objects from a two-dimensional video is difficult due to the lack of depth information at the boundaries between different objects. As the motion incoherency of a region is intrinsically linked to the presence of such boundaries and vice versa, a failure to recognise a discontinuity in the motion field, or the use of an incorrect motion, often leads directly to errors in the segmentation result. In addition, many defects in a segmentation mask are also located in the vicinity of moving object boundaries, due to the unreliability of motion estimation in these regions. The approach to segmentation in this work comprises of three stages. In the first part, a phase-based method is devised for detection of moving object boundaries. This detection scheme is based on the characteristics of a phase-matched difference image, and is shown to be sensitive to even small disruptions to a coherent motion field. In the second part, a spatio-temporal approach for object segmentation is introduced, which involves a spatial segmentation in the detected boundary region, followed by a motion-based region-merging operation using three temporally adjacent video frames. In the third stage, a multiple-frame approach for stabilisation of object masks is introduced to alleviate the defects which may have existed earlier in a local segmentation, and to improve upon the temporal consistency of object boundaries in the segmentation masks along a sequence. The feasibility of the proposed work is demonstrated at each stage through examples carried out on a number of real video sequences. In the presence of another object motion, the phase-based boundary detection method is shown to be much more sensitive than direct measures such as sum-of-squared error on a motion-compensated difference image. The three-frame segmentation scheme also compares favourably with a recently proposed method initiated from a non-selective spatial segmentation. In addition, improvements in the quality of the object masks after the stabilisation stage are also observed both quantitatively and visually. The final segmentation result is then used in an experimental object-based video compression framework, which also shows improvements in efficiency over a contemporary video coding method.

臺灣英語教學碩士論文中文獻探討章節之語步分析 / Move structure of literature review in Ma theses by Taiwanese TEFL Graduates蕭政華, Hsiao, Cheng Hua Unknown Date (has links)
在學術論文寫作眾多章節中,文獻回顧章節是讀寫過程中困難度較高的一章節,因此研究生普遍視為畏途。文獻回顧的語步分析在過去文獻中尚未受到重視。因此本論文旨在分析臺灣英語教學碩士論文中文獻回顧章節之語步結構。本論文提出兩個研究問題: (1)臺灣英語教學碩士論文文獻回顧章節之語步結構為何?(2)評選高分與評選低分的文獻回顧差異為何?本論文選出三十篇臺灣英語教學碩士論文中文獻回顧章節做為文本分析並將其評選高分群與評選低分群。本研究以四個主要語步來分析文獻回顧章節的語步結構。這四個主要語步分別為:(1)領域知識觀念介紹,(2)用主題方式整合過去之文獻,(3)聯結過去文獻與將進行之研究之關係,及(4)宣布將進行研究。每一主要語步都有數個次要語步。本論文討論語步出現的頻率,語步發展,語步組合結構及語步循環。
本論文顯示第一語步使用的最為廣泛佔56.96%,第二語步佔22.39%,第三語步與第四語步各為11.74%與8.91%。收集之文獻回顧分為四組,分別為(1)表現最差,(2)表現較差,(3)表現稱職,及(4)表現最好。 結果發現表現最差的一組沒有任何主題發展,表現較差的一組有主題發展但是僅限於整合,表現稱職的一組有運用到四個主要語步,而表現最好的一組發現有數個全部語步的循環。本論文呈現臺灣英語教學碩士論文文獻回顧章節的語步結構。這些結果與討論提供英語教學領域研究生更加了解學術論文文獻回顧之寫作架構。 / Reviewing literature for a research study is a highly complicated reading and writing process, which has been assumed a rather formidable task for many graduate students. In the field of English for Specific Purposes, many scholars have devoted their studies into certain types of genre analysis, particularly research genres. However, the concept of “literature review” (LR) as a distinct type of genre has been constantly overlooked and the move structure of literature reviews unexplored.
The move structure of LRs in master theses written by Taiwanese TEFL program graduates was studied. This proposed study included two research questions: (1) What are the move structures of the LR chapters in the master theses of TEFL programs? (2) Do the move structures differ between the low-rated and high-rated LRs? In this study, thirty theses were randomly chosen. Thirty theses were rated and grouped into high-rated and low-rated categories. Based on Kwan’s framework (2006) and the results of pilot study, a new move structure with the four major moves was formulated for this study.
The statistical results showed that “conceptualizing themes in a field (Move 1)” takes the largest proportion among the total occurrences, followed by “integrating previous works on the themes (Move 2),” “relating previous works to the current study (Move 3)” and “advancing to one’s own study (Move 4).” It is concluded that LRs composed by these graduates fundamentally serves to present relevant field knowledge. Further, no topic expansion is found in the deficient group. Most of the LRs in the poor group halt at the synthesis though there is some topic development. The competent group has a complete occurrence of the four major moves. Multiple cycles are found per LR in the distinctive group. This study provides insights into the move structure of Taiwanese students’ literature review chapters of master theses.

Marketing health issues to tweens : recommendations for reaching this demographic more effectivelyKelly, Erin Joy 20 February 2012 (has links)
This paper explores public health campaigns as they relate to tweens and their use of technology. After considering how this demographic utilizes both traditional and new media, further examination was done on general health problems that affect this group. Three major health issues were then chosen for analysis. A relevant campaign for each issue was also evaluated, as were its overall marketing and communication efforts. The health problems and corresponding campaigns chosen include childhood obesity and the “Let’s Move” campaign, electronic aggression and the “Stop Bullying” campaign and youth suicide and the “WeCanHelpUs” campaign. From these analyses, recommendations for ways to improve each campaign were provided, as were general conclusions for reaching this demographic more efficiently and effectively. / text

SENTIDOS E SIGNIFICADOS PARA O SE-MOVIMENTAR NA DANÇA EM CADEIRA DE RODAS / SENSES AND MEANINGS FOR THE "SELF-MOVE" ON WHEELCHAIR DANCERigo, Laís Cavalheiro 21 March 2016 (has links)
Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / We come upon critical about to dance and doing dance through techniques or "nontechnical"
based in the repetition and copying movements, studies that warn us to the
necessity of theoretical insights to legitimize dance and to dance as an expression
and communication. Thinking about Wheelchair Dance (DCR) as a manifestation of
increasing dance in search of spaces beyond the standardization of movements and
gestures, we traced as the central objective of this study was to establish
relationships between the Theory of "Self - Move Human" with the DCR teaching. To
do this, we long constitute theorists deepening about the Dance that originated notes
on aspects inherent the theme, as expressiveness, sensitivity, perception, body and
creativity. From this we outline of intervention possibilities for DCR teaching. We
understand that they ought not to study, research, write about Dance, one consisting
phenomenon of imperceptible variables, by following a predefined method, based on
certain assumptions. We commit to develop a theoretical research, a reflection on
Dance, incited to argue and write about this phenomenon, enabling new syntheses
go to meet the sense and meaning from our study, of our work. We find, in the
dialogic relationship movement, possibilities for "doing dance" of expressive and
communicative way, taking into account the senses and meanings intertwined in the
movement of the subject danceable. / Deparamo-nos com as críticas acerca do dançar e do fazer dança por meio de
técnicas ou não técnicas embasadas na repetição e cópia de movimentos, estudos
que nos alertam à necessidade de aprofundamentos teóricos para legitimar a Dança
e o dançar enquanto expressão e comunicação. Pensando na Dança em Cadeira de
Rodas (DCR) enquanto uma manifestação de Dança crescente em busca de
espaços para além da padronização de movimentos e gestos, traçamos como
objetivo central deste estudo estabelecer relações entre a Teoria do Se-Movimentar
Humano com o ensino da DCR. Para isso, ansiamos constituir aprofundamentos
teóricos sobre a Dança que originaram apontamentos sobre aspectos inerentes ao
tema, como expressividade, sensibilidade, percepção, corpo e criatividade. A partir
disso, delineamos possibilidades de intervenção para o ensino da DCR.
Compreendemos que não convém estudar, pesquisar, escrever sobre a Dança, um
fenômeno constituído de variáveis imperceptíveis, seguindo um método predefinido,
alicerçado em pressupostos determinados. Comprometemo-nos a desenvolver uma
pesquisa teórica, uma reflexão sobre a Dança, incitados a argumentar e a escrever
sobre esse fenômeno, possibilitando às novas sínteses ir ao encontro do sentido e
do significado do nosso estudo, do nosso trabalho. Encontramos, na relação
dialógica de movimento, possibilidades para um fazer dança de forma expressiva e
comunicativa, levando-se em consideração os sentidos e os significados imbricados
no movimento do sujeito dançante.

« The place to be ? » Vivre et bouger dans les entre-deux : jeunesse et mobilités dans les espaces périurbains / ‘‘The place to be ?’’ Living and commuting within the “space-in-between” / young commuters in the periurban fringes of the Great ParisDidier-Fèvre, Catherine 29 September 2015 (has links)
Cette thèse de doctorat mène une réflexion sur les mobilités juvéniles périurbaines sous l’angle de « l’entre-deux », terme caractérisant à la fois les espaces périurbains et la jeunesse. Comment la jeunesse vit-elle une localisation résidentielle, choisie par les parents, et se déplace-t-elle dans ces espaces peu densément peuplés et faiblement desservis par des transports en commun ? Quel rôle jouent les contextes périurbains dans la construction identitaire des jeunes ? L’étude menée, à partir de trois lycées généraux et technologiques situés dans les franges de l’agglomération parisienne en proie à un mouvement de périurbanisation plus ou moins ancien, a consisté à interroger une population lycéenne périurbaine par le biais de méthodes qualitatives (85 entretiens) et quantitatives (1522 sondés en ligne). Développant un ancrage différencié à l’espace habité dans lequel la maison individuelle tient une place centrale, les jeunes adoptent une multitude de stratégies pour s’émanciper des contextes périurbains. Ils combinent les ressources des entre-deux pour s’affirmer en tant qu’individu, y compris dans le cadre de la socialisation secondaire marquant cet âge. Ils y trouvent ainsi leur bonheur, bien qu’ils cherchent souvent, de manière plus ou moins réaliste ou réalisable, à sortir de ces espaces. Ces bricolages spatiaux les amènent à développer une motilité (Kaufmann, 2002) plus importante que celle des jeunes urbains. En revanche, à l’heure de s’inventer une vie adulte, ce n’est pas tant l’espace périurbain qui apparaît comme un obstacle à leur projet que les ressources sociales, financières ou culturelles de leur famille. Malgré tout, les contextes périurbains, parce qu’ils font territoires, sont des lieux où les jeunes projettent volontiers leur vie future, même si, pour certains, l’attraction urbaine ou de l’étranger est plus forte. / The ‘‘space-in-between’’ refers to any specified situation or space characterizing an intermediary and transitional state. This paper aims at exploring the notion of “space-in-between” through the themes of mobility and the youth living in the periurban fringes of the Great Paris. How does the youth live the residential choice of theirs parents and move to those median zone between rural and urban areas where public transit is deficient? What role have the periurban fringes in the building of the youth identity? Across this research, led in three public high schools located in the periurban fringes of the Great Paris, 85 young spoke about their mobilities and 1522 answered a questionnaire. Become oneself ask to move alone, to explore new spaces without parents but with peers, so these young people combine a lot of means to leave these spaces (walking, hitch-hiking, car-sharing, taking school buses for shopping and so on). Developing a specific link with the periurban areas where the home could be perceived as a special place, these young people live happily and do not consider themselves as ‘‘prisoners’’ in their territories. Nevertheless, they try to going out of them: going to parties, meeting other young people in the night clubs, meeting their friends as they want, practising sport and cultural leisures, and moving anywhere without asking their parents to drive them. At the time to become an adult, when they want to follow high education currucula, if they don’t choose the same way that urban and rural students, it seems that financial ressources and capacities to move are central in their choice. Some of them want to live in big cities or in foreign countries but most of them imagine them living the perurban edges where they had grow up. So the periurban fringes seem, as territories, the ‘place to be’! / El « espacio de transición » es una situación o un espacio que se caracteriza por ser intermedio.Aquella idea de intermedio interesa a los geografos en sus investigaciones sobre el espacio periurbano. Este proyecto , como continuidad de un precedente trabajo de investigaciones (Ser joven en el periurbano de SENS. ¿ Qué movilidades para los alumnos del instituto JANOT ? ; Catherine DIDIER-FEVRE, Máster 2 investigaciones, 2011. 229 páginas), intenta explorar la noción de « transición » a través de las movilidades. Si el término periurbano se define por un espacio de transición (noción aparecida con la instalación de la población en una extensión de la zona urbana) entre dos contrapuestos : espacio urbano y espacio rural, el de la juventud responde también a la noción de « espacio de transición ». En efecto, la juventud es la transición entre la desaparición de las claves de la infancia y la construcción de nuevos modelos. Es un tiempo de experiencias.Mientras « el periurbano sigue siendo el espacio de la juventud en una sociedad envejeciéndose : es el único espacio donde encontramos más de 3 jóvenes para con 2 mayores», muy pocas cosas fueron escritas sobre la juventud del periurbano. Aquella idea de las movilidades de la juventud es nueva. Tener en cuenta la edad de los habitantes de un espacio definido es fundamental para entender las relaciones de ellos con su territorio. Hasta ahora sólo los mayores o los niños pequeños preocuparon a los geografos del periurbano. Al investigar sobre los jóvenes del periurbano una se pregunta :¿Qué relaciones viven los jóvenes con el territorio periurbano al vivir una movilidad singular ?

‘Children on the move are children first’ : A Critical Analysis of Position Papers on Children on the Move from the European Network of Ombudspersons for ChildrenMaddocks, Rhiannon, Ulvfot, Ronja January 2018 (has links)
With children on the move at the forefront of policy-making and research in Europe in recent years, it has been argued that children’s rights are increasingly encroached upon through tighter immigration controls and inconsistent policy interventions. The European Network of Ombudspersons for Children (ENOC) is an institution that aims to address children’s rights violations at a regional level throughout Europe, meaning that it should in its promotion of core children’s rights ensure a balance is reached between provision, participation and protection in addressing policy problems relating to children on the move. Through a discourse analysis this thesis critically examines how problems are represented in ENOCs position statements, and how ENOC represent and construct children and childhood in relation to children on the move. Our analysis indicated that the statements were predominantly based within a rights-based approach, especially where longer-term strategies were promoted. This reveals that ENOCs emphasis on the need for children’s rights to take precedence over state sovereignty, that children’s rights to participation and non- discrimination is accentuated over child protection perspectives, and that the recognition of the heterogeneity of the experiences of children on the move is endorsed. However, whilst ENOC seeks to move away from stereotypical notions of the migrant child, by promoting their agency and heterogeneity, children on the move are also represented in isolation in the position papers. Disassociated from family and adult migrants, children on the move are constructed as victims, vulnerable, dependent and in need of special care and assistance. In this light, their construction conveys a notion of complexity, however, it is also evident that their vulnerability is fostered in order to receive the protection and support they are entitled to, whether at a regional, European or international level.

O brincar e a indústria cultural: é possível salvar a criança? / The playing and the cultural industry: is it possible to save the child?Burckardt, Eduarda Virginia 16 February 2017 (has links)
This study consists of restlessness and the desire to know the child and his relationships with
the toy and play. In order to understand the affinity that is established between the artifacts
produced by the Cultural Industry, which we will call industrialized toys and play, more
precisely the “play and self-move” of the child. To do so, to think the child in his world of
play and its relation with the industrialized toy, it is necessary to confront them with the social
and cultural processes that portray contemporaneity. This research is characterized as a
Theoretical Research, which intends to seek more elements to discuss this theme, seeking to
dialogue with different authors in order to increase the studies on the subject. Thus, the work
builds a dialogue placing the child and his play, debating some fundamentals with more recent
criticism about the involvement increasingly intense and precocious child with the adult´s
world. Then we will deepen the look at the Cultural Industry and its reflections on the life of
the child, their forms of invasion in the universe of children and highlighting the electronic
toys and the technological demands and their possible crossings in the development of the
child. Without pretensions to present a solution, but in the intention of launching an alert, for
teachers and adults in general, we focus on the understanding of play and self- move as a
possibility to think the child in its essence, valuing their perceptions of living the now, in its
potentialities and possibilities that are discovered through the curiosity of children, and thus,
establishing a dialogue with the world. In this way, this writing proposes to debate the
intentions of the industrialized toy and the play in its essence, trying to problematize the
importance of playing and self-move, proposing an alert to the institutions of early childhood
education. / Este estudo consiste na inquietação e no desejo de conhecer a criança e suas relações com o
brinquedo e o brincar. Com o objetivo de compreender a afinidade que se estabelece entre os
artefatos produzidos pela Indústria Cultural, designados de brinquedos industrializados, e o
brincar, mais precisamente o “brincar e se-movimentar” da criança. Para tanto, pensar a
criança no seu mundo de brincar e sua relação com o brinquedo industrializado, é necessário
confrontá-los com os processos sociais e culturais que retratam a contemporaneidade. Esta
investigação é caracterizada como uma Pesquisa Teórica, a qual tem a intenção de buscar
mais elementos para debater esta temática, procurando dialogar com diferentes autores, na
intenção de alargar os estudos sobre o tema. Assim, o trabalho constrói um diálogo situando a
criança e o seu brincar, debatendo alguns fundamentos com críticas mais recentes sobre o
envolvimento cada vez mais intenso e precoce da criança com o mundo do adulto. Também
aprofundar o olhar para a indústria cultural e seus reflexos na vida da criança, suas formas de
invasão no universo infantil, ressaltando os brinquedos eletrônicos, as demandas tecnológicas
e seus possíveis atravessamentos no desenvolvimento da criança. Sem pretensões de
apresentar uma solução, mas na intenção de lançar um alerta para professores e adultos de
maneira geral, o estudo se debruça sobre a compreensão do brincar e se-movimentar como
uma possibilidade de pensar a criança na sua essência, valorizando as suas percepções de
viver o agora, nas suas potencialidades e possibilidades que são descobertas por meio da
curiosidade, que, assim, vai estabelecendo um diálogo com o mundo. Dessa forma, esta
escrita se propõe a debater as intenções do brinquedo industrializado e o brincar na sua
essência, buscando problematizar a importância do brincar e se-movimentar, tecendo algumas
considerações às instituições de educação infantil.

Estratégias retóricas de distribuição de informação e a sinalização léxico-gramatical em introduções de dissertações de mestrado na área de alemão da USP/São Paulo e da LMU/Munique / Cutural translation: the image of Brazil in Do Outro Mndo, by Ana Maria MachadoKathrin Stefanie Schweiger 30 May 2011 (has links)
A presente pesquisa trata da descrição e da análise de estratégias retóricas que abrangem a distribuição e organização funcional e conteudística de segmentos textuais de introduções de dissertações de mestrado. Para o fim proposto, os textos de introduções foram extraídos de dissertações de mestrado do Institut für Deutsch als Fremdsprache/Transnationale Germanistik da LMU de Munique e da Área de Alemão da USP, Brasil, escritas nas línguas de cada país: alemão e português. O corpus é composto de 44 textos de introdução. Com base na perspectiva linguístico-contrastiva, as constatações da retórica contrastiva, juntamente com a análise de gênero de orientação sócio-retórica, formam os fundamentos teóricos desse trabalho. Com o intuito de determinar a distribuição e a organização dos segmentos textuais, foi empregado o modelo CARS de SWALES (1990, 2004), desenvolvido inicialmente para analisar a estrutura organizacional de introduções científicas do gênero artigo. A prioridade da presente pesquisa foi a de identificar e localizar as estratégias que o autor da dissertação de mestrado utiliza, para apresentar seu próprio trabalho (movimento 3 de Swales). Devido à grande variação da sequência de estratégias retóricas não foi possível determinar um modelo organizacional claro dos textos nas duas línguas. Contudo, a descrição dos dados tornou possível a constatação de estratégias principais e secundárias empregadas na apresentação dos próprios trabalhos. Incluem-se entre as estratégias principais: a) a denominação do estabelecimento de metas, b) indicações sobre o método de procedimento, assim como c) indicações sobre a estrutura textual. Adicionalmente, é importante para os autores dos textos em questão indicar o que o trabalho não é capaz de realizar, uma estratégia não existente no modelo de Swales e que, para as introduções das dissertações de mestrado consideradas, é essencial. Contextos diferentes da produção (como, por exemplo, posições com graus hierárquicos distintos) conduzem a uma valorização diferente nas metas comunicativas, fazendo com que, por exemplo, o movimento 3 tenha um papel mais importante nas introduções de dissertações do que em artigos científicos, nos quais a revelação de uma lacuna de pesquisa é muito importante. Além da identificação e da organização de estratégias retóricas, também foi considerada a sua realização linguística e gramatical no alemão e no português, assim como examinado o emprego dos pronomes pessoais que indicam as autorreferências. Assim, objetivou-se verificar em que papéis acadêmicos o autor aparece em seus textos. Os fundamentos teóricos empregados foram fornecidos por HYLAND (2002), STEINHOFF (2007) e SCHMIDT (2010). Como resultado é possível afirmar que a) os autores dos textos em português não seguem um mesmo modelo no que concerne ao emprego de pronomes pessoais, b) nos textos em alemão o autor quase não aparece, fazendo com que as referências de autor sem a presença do agente predominem, e c) nos textos em português e em alemão o autor aparece predominantemente na função de autor, isto é, quando, por exemplo, aparecem indicações sobre a organização textual. Os resultados deste trabalho têm como meta servir de subsídio para a produção de material didático que forneça aos futuros mestrandos recursos para a elaboração de textos de introdução nas duas línguas. / This study explores the description and analysis of rhetorical strategies utilized in the content-related distribution and organization of textual segments of master theses introductions. For this purpose, introduction texts were taken from masters dissertations of the Institut für Deutsch als Fremdsprache/Transnationale Germanistik of the LMU of Munich and of the German Department at Universidade de São Paulo, Brazil, each written in its respective national language: German and Portuguese. The corpus consists of 44 introductions. Due to the linguistic contrastive perspective, the findings of the contrastive rhetoric constitute the theoretical basis of this research, together with the genre analysis of socio-rhetoric orientation. In order to determine the distribution and disposal of the text segments, the CARS model by SWALES (1990, 2004) was employed. This model was initially developed to analyze the organizational structure of scientific introductions of research articles. The primary focus of this study is to identify and locate the strategies that each dissertation author uses to present its own work (Swales move 3). Due to a great variety of rhetoric sequences, it was not possible to determine a conclusive organizational structure of the texts in either language. However, a description of the data made it possible to determine primary and secondary strategies employed in the presentation of master theses. Primary strategies include: a) indication of goal setting, b) indications concerning the methodical procedure, as well as c) indications about the structure of the text. Furthermore, it is important for the authors to indicate what cannot be achieved, a strategy which is not considered by Swales in his model and which is essential for the analyzed introductions of masters dissertations. Different production contexts (as, for example, positions with different hierarchical degrees) lead to a different valuation of the communicative goals, having as a result that, for example, move three in master thesis introductions plays a more important role than in scientific articles, in which the indication of a research gap is of great importance. In addition to the identification and organization of rhetoric strategies, linguistic and grammatical use in German and Portuguese was also considered, as well as the use of personal pronouns that indicate references to the author depending on the agent. The intention was to verify in which academic rules the author appears in his texts. The theoretical fundamentals employed were based on HYLAND (2002), STEINHOFF (2007) and SCHMIDT (2010). As a result, it is possible to state that a) the authors of texts in Portuguese do not follow the same model concerning the use of personal pronouns, b) in the German text the authorial presence is frequently hidden behind passive forms c) in the Portuguese, as well as in the German texts, the author appears mainly in the rule of the agent, for example, when indications about the textual organization appear. The results of this work intend to serve as a basis for the production of didactic materials by providing instruments for future masters students to employ in the production of introduction texts in both languages.

The Kiruna town move : Unearthing the possibilities for full-scale fire testsPettersson, Henrik, Thörn, Adam January 2021 (has links)
The work with this thesis started during the last semester at the Fire Protection Engineering program at Luleå University of Technology. Kiruna has relied on the iron ore resources of Luossavaara and Kiirunavaara since the creation of the town. The iron ore stretches underneath the current city center. Therefore, some of the housings have to move northwest. The consequences of the town move are that some of the current housings will be demolished after the government owned mining company LKAB has bought the estates. This thesis aims to research the possibilities of performing fire tests in theses abandoned housings. Full-scale fire tests are usually expensive and therefore it is of substantial importance that the performed tests are meaningful. A meaningful full-scale fire test, in the author’s opinion, is defined as: The goal has to be well defined with a structured definition of what should be achieved. The test should aim at over-bridging knowledge gaps in the fire engineering science. The test should not be suitable executing for a laboratory environment. Earlier performed fire tests and scientific papers where studied to identify possible knowledge gaps. Four main topics where identified: FDS validation and computer modeling Passive fire protection system in old buildings Load bearing systems Façades and exterior claddings Two field inventories were conducted during 2016-2017. Some objects had a cultural value and were therefore excluded. The authors have decided to only include objects deemed interesting. However, these objects are just a small amount of the buildings affected by the move. The majority of the buildings identified as suitable for fire tests are high-rise residential buildings. These were found suitable for most of the identified topics. The number of buildings with large open spaces, large ceiling heights and atriums was small. The environmental requirements and permits required for performing fire tests were studied as a part of the thesis. The County administration of Norrbotten is in charge of these legal matters. The authors conclude that the authorization process may be lengthy and complicated but feasible. The authors’ conclusion is that the probability of performing full-scale fire tests are low. The lack of complex buildings, difficulty in extracting accurate, reliable data and high costs are some of the reasons. / Detta examensarbete påbörjades under den sista terminen vid brandingenjörsprogrammet på Luleå tekniska universitet, höstterminen 2017. Kiruna har sedan staden grundades alltid varit beroende av de järnmalmsfyndigheter som finns Loussavaara och Kiirunavaara. Den järnmalmsåder som löper från Kiirunavaara sträcker sig under stadens befintliga stadskärna. Delar av staden kommer därför att flyttas i nordvästlig riktning. Stadsflytten medför att delar av stadens bebyggelse kommer att köpas upp av det statliga gruvdriftsbolaget LKAB som sedan river fastigheterna. Arbetet syftar till att undersöka möjligheten att utföra brandförsök i dessa tomma fastigheter. Försök i full skala är mycket kostsamma vilket medför att det är eftersträvansvärt om brandförsöket är meningsfullt. Ett meningsfullt brandtest i full skala definierades av författarna som följande: Målet som försöket ska uppnå och vad som ska mätas är tydligt definierat Försöket ska överbrygga eller syfta till att överbrygga kunskapsglapp inom brandforskningen Försöket ska inte vara lämpligt att utföra in en laboratoriemiljö För att uppnå kravet avseende kunskapsglappet undersöktes tidigare brandförsök och vetenskapliga tidskrifter. Fyra huvudspår identifierades: FDS validering och datormodellering Passivt byggnadstekniskt brandskydd i äldre byggnader Lastbärande system Fasader och fasadbeklädnader Inventeringen gjordes i två omgångar under 2016 och 2017. Vissa objekt sållades bort på grund av dess kulturhistoriska värde. Inventeringen visar de objekt som författarna finner intressanta sett till ovanstående men representerar bara ett urval av alla de byggnader som evakueras i samband med flytten. Sett till de byggnader som under inventeringen identifierades som lämpliga för brandförsök utgörs de flesta av höga bostadshus. De höga bostadshusen bedömdes som lämpliga för samtliga identifierade huvudspår. Byggnader med stora öppna ytor, höga takhöjder eller atrium förekom ej förutom i ett fåtal fall. Som en del i arbetet undersöktes de miljötillstånd som krävs. Länsstyrelsen i Norrbotten som är den instans som beviljar eller avslår tillstånd. Författarna bedömer processen som omfattande men genomförbar. Sannolikheten för försök i full skala i samband med stadsflytten bedöms som låga. Bristen på komplexa byggnader, svårigheten i att extrahera exakta och tillförlitliga mätvärden samt den höga kostnaden medför att det är svårt att driva projektet så långt att det leder till försök i full skala.
