Topologioptimering är ett populärt och effektivt verktyg för att hitta smarta designer utformade för att fungera optimalt. Det aktuella forksningsarbetet presenterar en metod för att kunna optimera strukturer som utsätts för varierande laster där det inte är uppenbart var, eller när de högsta spänningarna kommer uppstå. Detta innebär att robusta strukturer smidigt kan genereras som kommer hålla fö

Detta examensarbetet handlar om att forma en hemisfäroid från en platt honeycomb-skiva samtidigt som honeycomb-strukturen bibehålls. Honeycomb-strukturen är ett hexagonalt mönster som kan vara gjord av hexagoner, cirklar eller trianglar. Inom kartografi görs jordens sfäriska yta om till en platt representation i form av en karta. Omvandlingen är omöjlig utan förvrängning eller uppdelning i mindreThis Master thesis is about forming a hemispheroid out of a flat honeycomb while retaining the honeycomb structure through an even spread of deformation. The honeycomb structure is a hexagonal structure which can be made out of hexagons, circles or triangles. In cartography the surface of the earth, a spheroid, must be distorted or cut up in order to create a flat map. In the same way forming of

How does democracy affect income inequality? Most would expect democracy to reduce income inequality. There is a general consensus that indeed democratizations in Europe during the nineteenth and early twentieth century did decrease income inequality. More recent democratizations, those countries that democratized during the 1970s-1990s, however, do not seem to have had the same effect. The body o

En fusion innebär att två eller flera bolag slås samman genom att samtliga tillgångar och skulder hos det överlåtande bolaget tas över av det övertagande bolaget och det överlåtande bolaget upplöses utan likvidation. Det finns två olika grundvarianter av fusioner, absorption och kombination. Absorption innebär att ett eller flera bolag fusioneras in i ett existerande övertagande bolag. KombinationA merger is a transaction in which at least two companies are merged by all the assets and liabilities of the transferring company being taken over by the acquiring company and the transferring company being dissolved without liquidation. There are two different versions of mergers, “absorption” and “combination”. Absorption means that at least one company is merged into an existing acquiring comp

Grön vätgas har lagts fram som en lösning på en av vår tids största utmaningar: Att klara av världens energiförsörjning samtidigt som de fossila bränslena avvecklas. Framför allt i sektorer som industriell kemikalieproduktion och långdistans-transport, där övergången till förnybar elektricitet är svårare. Grön vätgas produceras genom elektrolys, där en elektrisk ström driver den annars icke-spontaDue to increasing global energy demands and a need to move away from non-renewable energy sources, green hydrogen is now being considered as a possible replacement for fossil-based energy sources. Especially in “hard-to-abate” sectors, such as steel and petrochemical production, and long-distance transport, where the change to renewable electricity is more difficult. Green hydrogen is produced thr

Meteoritnedslag har spelat en grundläggande roll som ytmodifierande processer på jorden och andra himlakroppar. De har haft stor betydelse för omstruktureringen av jordskorpan, bassängbildning samt bildan- det av magmatisk och hydrotermal aktivitet. Av de cirka 200 nedslagsstruktur som identifierats på jorden har de flesta bildats på land, medan betydligt färre exemplar finns bevarade från marina Impact cratering has played a fundamental role as a surface modifying process on Earth and other celes- tial bodies. It has significantly influenced crustal reshaping, basin formation and the development of magmatic ac- tivity and hydrothermal systems. Of the roughly 200 impact structures that have been identified on Earth, the ma- jority occurred on land, with significantly fewer known examples p

We propose data-driven surrogate models to solve systems of time-dependent differential equations coupled with noise. Using a feedforward neural network, we separately learn the noise and solution, tackling approximations across regimes with bifurcations and rare events. Focusing on irregular data generated by a stochastic noise model on a one-dimensional spatial lattice coupled to a differential

Population aging has tremendous economic consequences and generates an unprecedented pressure on the welfare state. As the number and share of ‘dependent’ people grows, the state struggles to finance pensions and health-related costs. In this optic, Sweden is no exception: the mean age of the population, life expectancy and share of people above 65 continuously increase – which warrants the focus

Despite many years of progress towards closing the gender pay gap and achieving racial equality, women from ethnic minority groups in the United Kingdom earn less compared to their male counterparts and to the population average. The extent of channelling into certain areas of occupation and employment are a prominent feature of the employment of minority groups in the UK and is a key mechanism in

The purpose of this study was to investigate how students experience being affected as recipients of psychological knowledge, through psychology lessons in high school. An explorative, qualitative study with eight semi-structured interviews was conducted. The high school students were in year 2 or year 3 and came from three different schools in Skåne county, Sweden. All had taken at least the majo

Supervisor: Anders Östnäs Assessor: Christina Erneling The purpose of the study was to describe and analyze of life values based upon different ages, in order to make comparison between them. Life values mean what you as an individual state as the most impo

This thesis is devoted to understand the relationships between the European Union (EU) and Russian Federation (RF). The study is concentrated on the fields of energy (Oil and Gas) in their strategic partnership. The events during the last century in the global energy markets have put the European Union face to face with new challenges. Obviously, it is claimed that growth dependency on Russian ene
