Ofta vill man använda numeriska metoder för att kunna simulera verkligheten. Det kan handla om att simulera rörelser, elektroniska kretsar och mycket annat. Detta arbete handlar framför allt om hur man kan simulera utbredning av värme. I många situationer där man skulle vilja simulera till exempel uppskjutningen av en raket, bromsandet av ett bilhjul eller mekanismen i ett kylskåp – så stöter man We construct and analyze Dirichlet-Neumann iterations for the 1D Poisson equation. Specifically, we wish to gain insight into how the convergence depends on material coefficients when solving coupled linear heat equations on three non-overlapping domains. We first consider the two-domain case and then extend the method to three domains. A finite element method is used to discretize the Laplacian.

This master thesis discusses the opinions of different people regarding new additions to present historic settings. The thesis´ starting-point is that additions and alterations have to be made; the question is how these additions can be made in a way that shows full respect of the old building and, at the same time, adds something new. Through interviews with four different groups of people, I wan

En av de absolut största utmaningarna inom modern fysik är att beskriva beteendet hos system som består av många partiklar eller föremål som alla interagerar med varandra, så kallade interagerande mångkroppssystem. Solsystemet är ett sådant system, där solen, planeterna och alla månar interagerar med varandra genom tyngdkraften. En annan typ av mångkroppsystem är kristaller. En kristall består aThe physics of interacting many-body systems is a very complex and challenging subject. Therefore one in general needs to use simplified models and approximate methods for studying these systems theoretically. In this work we study the exchange-correlation (xc) potential for the Hubbard-Holstein (HH) model for the application of Density Functional Theory (DFT) to the same. The Hohenberg-Kohn theo

Hållbar utveckling är ett övergripande mål i samhället. En viktig aspekt i ett hållbart samhälle är återvinning av material. Det handlar om att värna och nyttja givna resurser på ett hållbart sätt. Asfalt är den vanligaste vägbeläggningstypen i Sverige och utgörs av bitumen, filler, stenmaterial och eventuella tillsatser. Bitumen och stenmaterial är två ändliga naturresurser som är återvinningsbarSustainable achievement is the overall objective of all road building undertakings. An important part of this is recycling. Reclaimed asphalt is not only renewable but contains vast volumes of finite resources and the interest for the recycling modes of operation is on the rise. However, the impact of additives and the production processes must not adversely affect the properties of the pavements

The aim of this study was to investigate the motivational work in needle exchanges. The analysis was based on two theories; a theory of Per Revstedt and the pygmalioneffect. The study is based on qualitative interviews with seven person (six women and one man) who work in needle exchanges. The interviews is later analysed. The results show that the respondents express that the goal with the motiva

I denna kvalitativa studie intervjuades 17 beställare av ledarskapsutbildningar i Skånes näringsliv om deras syn på sitt företags behov av ledarskapsutveckling. Resultaten vittnar om behov av självinsikt, perspektiv, bekräftelse, stöd i rollen och ledarförmågor på individnivå och kulturell samsyn, välfungerande personal, affärsstrategisk stringens, effektiva arbetsprocesser och attraktivitet som a

The aim of this study was to examine how middle managers experience the impact of internal and external stakeholders bound to the organizations and how middle managers form their legitimacy. The study examined the complex situation of social workers in a middle managing position using stakeholder theory and legitimacy. The middle managers are working in Swedish welfare organizations providing supp

The aim of this study was to examine the employees experiences of the collaboration between the probation service, the social service and the labor office within the organization Krami. The study relies on six qualitative, semi structured interviews with two employees from each authority at two separate Krami offices. The organization aims to guide and help persons with former criminal backgrounds

The aim of this study is to investigate how school counselors describe control over their work situation and to conclude which factors compicate and ease the counselors to feel in control. This study is empirically based on semi-structured interviews of seven school counselors. The conclusions indicates that the counselors generally though they had control over their work although there were uncle

The aim of this study was to explore sea-level rise (SLR) exposure in South-East England by conducting a broad analysis of some of the possible impacts of inundation in the region under different SLR scenarios in a warming climate. The potential effects of coastal inundation were mapped and quantified by applying a modified bathtub modelling approach in GIS to a low-elevation coastal Digital Terr

It is still not well defined how the anatomy of the hip in healthy pediatric patients develop. Defining the span of normal anatomical development could help identify patients that deviate from healthy development and enable early diagnosis of certain pathological conditions of the hip. To study the normality range of the 3D morphology of the hip for pediatric patients, a statistical shape model (

Recently heavy rainfall frequency in Kyushu Island, the southwestern part of Japan, during the rainy season, has been increasing due to possibly climate change, global warming. Owing to the recent increase of heavy rainfall frequency, natural disasters related to heavy rainfall including flooding and landslides have occurred and caused serious damages to infrastructures and human lives. Therefore,

This thesis investigated how one can build a PowerLink network and Control Nodes that act as, e.g., sensor, actuators, etc., together with B&R:s products. Establishing different PowerLink networks was also investigated such as PLC connected to Raspberry Pi2. Configuration and step-by-step introduction of what PowerLink is and how it works is also mentioned in this thesis. In addition to creati

The aim of this study was to examine adolescents in the age ranging between 20-25, with one or two foreign-born parents from the former Yugoslavia, experiencing their identity as this is a group considered to be established and well integrated in the Swedish society. As the study was based on a qualitative method using focus groups, the questions in the group sessions were initially more structure

Housing first has been introduced as a new method in the field of social work, aimed at homelessness in Sweden. The conventional way of tackling homelessness has made it difficult for people in homelessness to access and retain housing. In the hands of the social services, housing programs, has developed into becoming a tool of control and surveillance. As a new approach to the issue of homelessne
