Kopplade differentialekvationer förekommer överallt inom vetenskapens värld. Några sådana exempel är för beräkning av värmeinteraktioner mellan två olika material, luftflödet runt en vinge och blodflödet i ett hjärta. Ett mer specifikt exempel är raketmotorer som riktar ett kraftigt gasflöde med ett munstycke. Detta munstycke blir deformerat på grund av värme och högt lufttryck. Dessa ändringar i This thesis presents and tests the convergence rate of the Dirichlet-Neumann algorithm for two Poisson equations coupled by transmission boundary conditions. Three second order discretisation methods are used when analyzing the convergence: standard equidistant finite difference, standard adaptive linear finite element, and standard adaptive finite volume discretisation of Poisson's equation.

Prostatacancer är den näst vanligast förekommande typen av cancer för män i världen. Att ha tillgång till ordentliga och tillräckliga diagnostiseringsverktyg är därför en avgörande faktor för hur väl vården kan hantera och behandla patienterna. Idag används Gleason gradering for att bedöma hur allvarlig cancern är. Metoden introducerades på 60-talet och går ut på att granska hur välstrukturerade cProstate cancer is one of the most common types of cancer for men, making proper diagnostic essential. Using machine learning as a tool to help in digital pathology has become increasingly popular and helps to limit the high intra observer variability between pathologists. Due to the many cases of prostate cancer and the large differences between tumours, treatments have to be individualized for e

Bakgrund: Psykisk ohälsa ökar i Sverige och alternativa behandlingsmetoder efterfrågas alltmer. Dock är evidensen bristfällig och trots att hästunderstödd rehabilitering är en aktivitetsbaserad rehabiliteringsform är arbetsterapeutisk forskning inom området nästintill obefintlig. Syfte: Att granska befintlig evidens avseende hästunderstödd rehabilitering för personer med psykisk ohälsa, med stöd aBackground: Mental illness is increasing in Sweden and more alternative rehabilitation methods are requested. The research is however inadequate and even though equine-assisted therapy is an activity-based rehabilitation form, the occupational therapy research on the matter is nearly non-existent. Aim: The aim of this study was to overview the existing evidence for equine-assisted therapy for pers

This study describes three young men and four young women and their quest for identity in a culture they, for many reasons, never seriously considered to be their own. The aim of the study was to find out, through interviews, what characterizes the culture of individuals identified as “blattar”, individuals with a cross-cultural background growing up and living in Sweden. We wanted to find out wha

The aim of this thesis was to explore the effect of domestic violence against women Health’s and Agricultural Activities in Otukpo Benue State, Nigeria. The sampling techniques adopted for this study is both cluster and purposive sampling in selecting respondents to participate in the study. The study area is divided into four cluster representing the four major districts of the study area. These

The present study investigates the following problem: What are the regulatory structures of land based transportation in the greater Copenhagen area? In order to obtain a comprehensive understanding of this problem, three sub questions were designed to target the structures in detail. These are: How do European regulations on the area of the land based transportation influence the subsidy process

Since the outbreak of the Syrian crisis in 2011,the number of Syrian refugees reached approximately 3 million; nearly half of them are children. Although primary education has always been available, education services for Syrian refugees were subject to frequent changes particularly between 2011-2014. The biggest and most significant step was taken in the 2016/2017 school year as a result of long-

This thesis aims to provide a case study for a critical theory of mythopoetics, via analysis of four ‘Brexit narratives’: The Bad Boys of Brexit by Arron Banks, Unleashing Demons by Craig Oliver, All Out War by Tim Shipman and The Brexit Club by Owen Bennett. My objective is to demonstrate the prevalence of mythopoetics in political and historical discourse, via analysis of four competing politica

Little is known about the spatial ecology of the Sunda clouded leopard (Neofelis diardi). Being rare and elusive rainforest dwellers, studying them is difficult. Basic knowledge on their home ranges and social organization is lacking, yet is crucial for maintaining viable populations in protected areas, in the scope of this Vulnerable species’ conservation. This study uses 10 years’ worth of came

Studiens syfte var att observera och beskriva hur fotbollstränare i en förening i södra Skåne agerar gentemot spelare i ett flicklag och pojklag. Utefter detta utformades studien samt uppsatsen. Vi använde oss av en öppen observation som design och ett observationsschema som instrument. Observationsschemat inspirerades av något äldre, tidigare forskning (Young, 1980; Andreasson, 2007; Fundberg, 20The study’s purpose was to observe and describe how football coaches in a club in southern Skåne acted towards players in a girls team and a boys team. The study and the paper was designed according to this purpose. We used an open observation as design and an observing schedule as an instrument. The observation schedule was inspired by older, previous research (Young, 1980; Andreasson, 2007; Fund

Calibration of robots is an essential part of industry today when there is a high accuracy requirement. Several calibration methods have proven to be highly accurate but also expensive and time consuming to use. In this thesis a new calibration method has been developed. The method does not depend on any external measurement systems but instead rely entirely on the robot’s own sensors. The method

Det pågår ständigt en utveckling för att minska både risker för miljö och hälsa inom den kemiska industrin. Oftast handlar det om att förbättra existerande processer eller att helt enkelt hitta nya vägar till samma produkt och i grunden ligger forskning bakom framgångarna.Polyurethane is a widely used polymer with a lot of different applications due to its versatility and often resilient properties. The polymeris often prepared as a two component system consisting of polyols and isocyanates and can be cured at relatively low temperatures. Even though the formed polymer is hazardless the isocyanate used in the manufacture is dangerous in itself, but even more so is

The automotive cooling system and thermal control strategy are important in order to reduce the pollution emission, extend the life of the components and reduce the fuel consumption. The scope of this thesis is to achieve a minimum model that works properly and a small library with the necessary components that the model could be made with. This will be the base for a future Engine Cooling library

Bostadssituationen i Sverige har under de senaste åren utvecklats i en oroande riktning. Den rådande bostadsbristen påverkar alla samhällsgrupper men de som drabbas hårdast är de som redan står längst ifrån bostadsmarknaden. De senaste årens ökning av den strukturella hemlösheten i Sverige har även ökat arbetsbelastningen hos den redan överbelastade socialtjänsten när hushåll som egentligen inte hThe current housing shortage affects all social classes but those most affected are the ones already furthest away from the housing market. The homelessness caused by structural factors has increased in Sweden during the last couple of years. It has led to an increased workload for the Social Services. Today, there is no unambiguous definition of social housing connected to the legal framework in

The COVID-19 pandemic has greatly transformed the world of academia, forcing many academics to begin working remotely, disrupting their work-life balance. Late-career academics are under-represented in the literature when it comes to their understanding of work-life balance and remote work. For this reason, we decided to combine the concepts of work-life balance and remote work, and explore the pe

Sitting in a high chair gives a feeling of security and of having control - you get an overview of the room you are in. But high chairs are often difficult to get up on, you feel clumsy, there is no good support for your feet and they are often quite uncomfortable. The research I have done shows that many people therefore reject the high chair, despite the positive feelings it can also give. Thos

The forest fire that started in the vicinity of Sala in Västmanland 31 July 2014 ended up in being considered to be the biggest forest fire in Sweden for decades. Crisis management as we knew it got a punch on its nose so to speak. Municipalities, fire departments as well as governmental organizations got involved in something they never handled before and maybe for the first time they all had to
