Är rika områden friskare än fattiga? : en studie av sambandet mellan ett områdes ekonomiska nivå och dess invånares hälsa

Eliasson, Tove January 2009 (has links)
En jämlikt fördelad hälsa är ett mål för den svenska folkhälsopolitiken, och därför är det viktigt att studera de sociala och ekonomiska faktorer som påverkar hälsan. Den här uppsatsen undersöker om det går att fastställa ett samband mellan medelinkomst och allmän hälsonivå i Sveriges församlingar. Tidigare studier visar att hälsan påverkas negativt av att leva under sämre ekonomiska förhållanden. Jag använder data från Socialstyrelsens patientregister från slutenvården samt IFAU-databasen och genomför en regression med hjälp av en fix effekt modell som rensar för områdesspecifika fixa effekter. Resultaten visar på ett negativt signifikant samband mellan medelinkomst och antalet inläggningar per capita i församlingarna. Jag testar även hur sambandet ser ut mellan medelinkomsten i ett område och tre specifika sjukdomsgrupper. Det verkar finnas negativa samband mellan medelinkomst och antalet inläggningar för mental ohälsa och hjärtkärlsjukdomar, men resultaten är inte robusta för modellens  specifikationsform. Jag kan inte fastställa något samband mellan en församlings medelinkomst och antalet inläggningar för infektionssjukdomar.

Density As A Transformative Power Of Urbanization: Milletvekili Lojmanlari / Park Oran Konutlari

Kale, Evrim Ozlem 01 August 2008 (has links) (PDF)
The economic and political restructuring of the 1980s whose main aim was to integrate Turkey to the global economic network via constructing &ldquo / global cities&rdquo / initiated not only new architectural programs such as grand shopping malls, office towers, world trade centers, five-star hotels but also new housing patterns all of which played an important role in shaping the urban character. As a result of these new architectural programs Ankara&rsquo / s urban landscape has been reterritorialized according to the logic of capital. The aim of this study is to analyze the effects of the emerging residential programs on Ankara&rsquo / s urban transformation since 2000. Specifically, this research critically concentrates on the process of transformation of a low rise-low density residential area into a high rise-high density residence through construction, deconstruction, and reconstruction of the same site initiating a &ldquo / re-scaled&rdquo / urban landscape. With this respect, this study endeavours to deal with the case of destructing the TBMM Milletvekili Lojmanlari for constructing Park Oran Konutlari.

Essas regras podem ser expressas como quick fixes que detectam e reescrevem padrões de código indesejados. No entanto, estender seus catálogos de regras é complexo e demorado. Nesse contexto, os programadores podem querer executar uma edição repetitiva automaticamente para melhorar sua produtividade, mas as ferramentas disponíveis não a suportam. Além disso, os projetistas de ferramentas podem querer identificar regras úteis para automatizarem. Fenômeno semelhante ocorre em sistemas de tutoria inteligente, onde os instrutores escrevem transformações complicadas que descrevem "falhas comuns" para consertar submissões semelhantes de estudantes a tarefas de programação. Nesta tese, apresentamos duas técnicas. REFAZER, uma técnica para gerar automaticamente transformações de programa. Também propomos REVISAR, nossa técnica para aprender quick fixes em repositórios. Nós instanciamos e avaliamos REFAZER em dois domínios. Primeiro, dados exemplos de edições de código dos alunos para corrigir submissões de tarefas incorretas, aprendemos transformações para corrigir envios de outros alunos com falhas semelhantes. Em nossa avaliação em quatro tarefas de programação de setecentos e vinte alunos, nossa técnica ajudou a corrigir submissões incorretas para 87% dos alunos. No segundo domínio, usamos edições de código repetitivas aplicadas por desenvolvedores ao mesmo projeto para sintetizar a transformação de programa que aplica essas edições a outros locais no código. Em nossa avaliação em 56 cenários de edições repetitivas de três grandes projetos de código aberto em C#, REFAZER aprendeu a transformação pretendida em 84% dos casos e usou apenas 2.9 exemplos em média. Para avaliar REVISAR, selecionamos 9 projetos e REVISAR aprendeu 920 transformações entre projetos. Atuamos como projetistas de ferramentas, inspecionamos as 381 transformações mais comuns e classificamos 32 como quick fixes. Para avaliar a qualidade das quick fixes, realizamos uma survey com 164 programadores de 124 projetos, com os 10 quick fixes que apareceram em mais projetos. Os programadores suportaram 9 (90%) quick fixes. Enviamos 20 pull requests aplicando quick fixes em 9 projetos e, no momento da escrita, os programadores apoiaram 17 (85%) e aceitaram 10 delas. / Tools such as ErrorProne, ReSharper, and PMD help programmers by automatically detecting and/or removing several suspicious code patterns, potential bugs, or instances of bad code style. These rules could be expressed as quick fixes that detect and rewrite unwanted code patterns. However, extending their catalogs of rules is complex and time-consuming. In this context, programmers may want to perform a repetitive edit into their code automatically to improve their productivity, but available tools do not support it. In addition, tool designers may want to identify rules helpful to be automated. A similar phenomenon appears in intelligent tutoring systems where instructors have to write cumbersome code transformations that describe “common faults” to fix similar student submissions to programming assignments. In this thesis, we present two techniques. REFAZER, a technique for automatically generating program transformations. We also propose REVISAR, our technique for learning quick fixes from code repositories. We instantiate and evaluate REFAZER in two domains. First, given examples of code edits used by students to fix incorrect programming assignment submissions, we learn program transformations that can fix other students’ submissions with similar faults. In our evaluation conducted on four programming tasks performed by seven hundred and twenty students, our technique helped to fix incorrect submissions for 87% of the students. In the second domain, we use repetitive code edits applied by developers to the same project to synthesize a program transformation that applies these edits to other locations in the code. In our evaluation conducted on 56 scenarios of repetitive edits taken from three large C# open-source projects, REFAZER learns the intended program transformation in 84% of the cases and using only 2.9 examples on average. To evaluate REVISAR, we select 9 projects, and REVISAR learns 920 transformations across projects. We acted as tool designers, inspected the most common 381 transformations and classified 32 as quick fixes. To assess the quality of the quick fixes, we performed a survey with 164 programmers from 124 projects, showing the 10 quick fixes that appeared in most projects. Programmers supported 9 (90%) quick fixes. We submitted 20 pull requests applying our quick fixes to 9 projects and, at the time of the writing, programmers supported 17 (85%) and accepted 10 of them.

Impact of thermal equilibriumassumption on modelling of coreuncovery in FIX-II experimentby APROS

Linder, Albert January 2018 (has links)
When simulating a thermohydraulic system, the general assumption isthat the conservation equations for mass, energy and momentum apply.And in such systems both liquid and gas exist, in this project liquidwater and steam. This report examines two different approaches tosimulate a thermohydraulic system. One is called 6-equation model,where separate conservation equations exist for both gas and liquid.The other is known as 3-equation model, where the conservationequations describe a mix of the two states. This examination is doneby modeling an experiment known as FIX-II in the software APROS, whichis capable of using both the 3- and 6-equation model. This reportshows that in several cases, both equation models give quite goodresults. However, whereas the 3-equation model in some cases, mainlypressure, were able to produce results more in line with experimentaldata, it struggled when it comes to counter current flow. Countercurrent flow, or CCF, means that gas and liquid flow in oppositedirections, something that the 3-equation model is unable to handle.For experiment 3051 this leads to a break flow in the 3-equation modelthat significantly deviates from experimental data. Generally, it isconcluded that the 3-equation model needs to be used with cautionbecause of its inability to deal with CCF. Besides CCF, there is alsoa significant difference between the two equation models in how heatflow is calculated. This difference in heat flow is the main reasonfor differences in pressure between the two equation models, which inturn caused the difference in break flow.

Fix-and-Optimize Heuristic and MP-based Approaches for Capacitated Lot Sizing Problem with Setup Carryover, Setup Splitting and Backlogging

January 2015 (has links)
abstract: In this thesis, a single-level, multi-item capacitated lot sizing problem with setup carryover, setup splitting and backlogging is investigated. This problem is typically used in the tactical and operational planning stage, determining the optimal production quantities and sequencing for all the products in the planning horizon. Although the capacitated lot sizing problems have been investigated with many different features from researchers, the simultaneous consideration of setup carryover and setup splitting is relatively new. This consideration is beneficial to reduce costs and produce feasible production schedule. Setup carryover allows the production setup to be continued between two adjacent periods without incurring extra setup costs and setup times. Setup splitting permits the setup to be partially finished in one period and continued in the next period, utilizing the capacity more efficiently and remove infeasibility of production schedule. The main approaches are that first the simple plant location formulation is adopted to reformulate the original model. Furthermore, an extended formulation by redefining the idle period constraints is developed to make the formulation tighter. Then for the purpose of evaluating the solution quality from heuristic, three types of valid inequalities are added to the model. A fix-and-optimize heuristic with two-stage product decomposition and period decomposition strategies is proposed to solve the formulation. This generic heuristic solves a small portion of binary variables and all the continuous variables rapidly in each subproblem. In addition, the case with demand backlogging is also incorporated to demonstrate that making additional assumptions to the basic formulation does not require to completely altering the heuristic. The contribution of this thesis includes several aspects: the computational results show the capability, flexibility and effectiveness of the approaches. The average optimality gap is 6% for data without backlogging and 8% for data with backlogging, respectively. In addition, when backlogging is not allowed, the performance of fix-and-optimize heuristic is stable regardless of period length. This gives advantage of using such approach to plan longer production schedule. Furthermore, the performance of the proposed solution approaches is analyzed so that later research on similar topics could compare the result with different solution strategies. / Dissertation/Thesis / Masters Thesis Industrial Engineering 2015

Estudo do desempenho hidrodinâmico de um leito fixo rígido com esferas de vidro sinterizadas para retenção de partículas / Experimental study of hidrodynamics performance of the rigid fix bed produced with spheres of grass for the retention of particles

Ernesto Beck Junior 10 May 2006 (has links)
Nesta dissertação de mestrado é estudado o desempenho fluidodinâmico de um meio poroso fixo e compactado, construído por sinterização com esferas de vidro para a retenção de partículas. A análise experimental visou o processo de retenção de partículas a partir de pastilhas circulares de diâmetro de 29 mm confeccionadas com esferas de vidro variando de 1,0 a 3,3 mm de diâmetro e sinterizadas como um elemento rígido a partir de aquecimento contínuo até cerca de 750ºC. As pastilhas foram submetidas a diferentes pressões de coluna de água, e a vazão no meio poroso foi analisada para diferentes pressões. Os experimentos foram realizados com a adição em batelada de polpa de açaí, areia fina, areia grossa e esferas de vidro próprias da composição do meio poroso. As vazões mássicas adimensionais são apresentadas graficamente para diferentes pressões de coluna de água variando entre 0,1 e 0,5 atmosferas (atm), em regime permanente e estacionário. Os resultados experimentais foram comparados e apresentados na forma de parâmetros adimensionais que caracterizam o regime de escoamento num leito fixo. Os resultados experimentais foram modelados a partir da modificação dos modelos de Vortmeyer e Schuster (1983) e Subagyo et al. (1998) para estabelecer sobre os mesmos parâmetros adimensionais uma adequada aproximação com os resultados teóricos. / The present dissertation reports the performance of steady flow in circular fix bed which was created by sinterization of glass spheres. The experimental analysis aimed the process of retention of particles from circular packed bed of 29 mm of diameter. The circular fix bed was created with spheres of glass of diameter between 1.0 and 3.0 mm, and made by sintering one rigid body from continuous heating until 750ºC. The circular and rigid fix bed was subjected to different pressures of column of water varying between 0.1 and 0.5 atm for analysis of flux (kg/s). The experiments were carried out with the addition of one amount of açai pulp, sands fine, sands thick and spheres of glass own of composition of fix bed. The dimensionless flux was present for different pressures of column of water on the fix bed; the results were compared and presented in the form of dimensionless parameters of literature what characterize the flow in packed bed. The experimental results were modeled based on Vortmeyer e Schuster (1983) and Subagyo et al. (1998) models, establishing on the dimensionless parameters an appropriate approach with the theoretical flux of circular fix bed.

DefectoFix : An interactive defect fix logging tool.

Hameed, Muhammad Muzaffar, Haq, Muhammad Zeeshan ul January 2008 (has links)
Despite the large efforts made during the development phase to produce fault free system, most of the software implementations still require the testing of entire system. The main problem in the software testing is the automation that could verify the system without manual intervention. Recent work in software testing is related to the automated fault injection by using fault models from repository. This requires a lot of efforts, which adds to the complexity of the system. To solve this issue, this thesis suggests DefectoFix framework. DefectoFix is an interactive defect fix logging tools that contains five components namely Version Control Sysem (VCS), source code files, differencing algorithm, Defect Fix Model (DFM) creation and additional information (project name, class name, file name, revision number, diff model). The proposed differencing algorithm extracts detailed information by detecting differences in source code files. This algorithm performs comparison at sub-tree levels of source code files. The extracted differences with additional information are stored as DFM in repository. DFM(s) can later be used for the automated fault injection process. The validation of DefectoFix framework is performed by a tool developed using Ruby programming language. Our case study confirms that the proposed framework generates a correct DFM and is useful in automated fault injection and software validation activities.
