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.
There is a common notion that economic freedom has a positive effect on economic development. However, despite formal institutions considered beneficial for economic freedom being increasingly recognised there persists large differences in economic development across the globe. A possible explanation can be found within the framework of informal institutions. Economic freedom being a transmission
The problem studied in this thesis is the impact of the principle of mutual trust on the possibility of EU nationals to claim asylum and avoiding extradition for political offences within the EU. The principle of mutual trust presumes that human rights are not violated in any EU Member State. The difficulty arises if and when human rights are actually violated. It is not clear to what extent funda
Due to high usage of fossil fuels the emissions of greenhouse gases has increased to dangerous levels during the last century. Something is needed to be done soon in order to reduce emissions and stabilize the climate. The transportation sector stands for a large part of these emissions and one way to reduce these could be to instead use electric vehicles. Unfortunately, today batteries limit the
In 2019 it was estimated that 50 million tonnes of e-waste was produced of which only 20% was officially recycled which has made the e-waste problem one of the most pressing environmental issues. As the current approaches to deal with the accelerating e-waste issue seemingly is falling short, the importance of utilizing alternative measures can no longer go unrecognized. Cloud computing has the ca
This project is inspired by my own journey of house hunting in 10 cities across 3 countries in last 10 years and the search continues These experiences have made me curious to explore the urban dynamics of this never ending housing demand in cities across the globe The thesis examines the parameters associated with rental housing deficiency in Berlin a city that offers diversity and opportunity at
More than 400 million people in the world have type 2 diabetes, making it one of the most common diseases internationally according to the World Health Organization. Thiazolidinediones (TZDs) is used to treat type 2 diabetes since it increases the sensitivity of insulin in peripheral tissues. The knowledge about the mechanism how TZD works is limited which has resulted in patients getting serious
This thesis investigates the role of marijuana use in labor productivity in the United States with the aim to contribute to the discussion and understanding of economic consequences of marijuana legalization. The data is sourced from various federal agencies to create a panel of 50 U.S. states and the District of Columbia for the period of 2005-2017. A panel data model with fixed effects is estima
The retail sector represents 11% of the GDP and employs 15% of the workforce in the European Union. To tackle growth of e-commerce, physical retail stores need to be reviewed; both to decrease operating costs, increase productivity and to make the shopping experience more appealing. Energy use for lighting accounts for 50% of the total energy use in non-food retail stores, which is consumed primar
This thesis provides a self-contained introduction to the Fundamental Group and presents some of its applications, such as Brouwer fixed point Theorem,the Game of Hex, Nielsen-Schreier Theorem, the van-Kampen Theorem and some of its consequences, Borsuk-Ulam Theorem and some of its applications,the Jordan curve Theorem, and some other examples and applications.Some results in Group Theory will be
Enzyme engineering for a better future It is essential for many organisms on this planet to be able to digest plants. One of those organisms is the blue mussel, which uses certain enzymes in its stomach to break down sugar fibers in the algae that it eats. But how does this really work, and can we use it for anything? Plant cells have very strong walls, protecting them from environmental stress.
Thesis purpose: In order to contribute to Consumer Culture Theory, as well as critical dimensions in the foodie literature namely authenticity, democracy/distinction and gender, the study’s aim is to explore how discourses and socio-cultural meanings underlie identity constructions in the specific sourdough culture. Theoretical framework: As no research addresses the sourdough phenomenon directly
Nowadays, very few public services could be delivered by only one department or organization. In order to deal with those "wicked" issues, like transportation, housing, environmental protection, food safety or some other problems, collaboration between departments has been a need. Meanwhile, cross-departmental collaboration has been proved to be an important means for governance, which h
Upprinnelsen till detta examensarbete var att Otis Stockholm, som också leder den svenska verksamheten, saknade en processkarta för nymontageavdelning. Försök hade gjorts tidigare med att göra en processkartläggning, men man hade då inte kommit hela vägen. Man ville nu från ledningens håll ha en karta på processen så att alla gjorde på samma sätt från projekt till projekt. Processen var uppdelad iThe impetus for this thesis was the identification of the need for a process map for processing new equipment within Otis Sweden. The company had tried before to map their process but had not fully developed the model. This time managers wanted a process map to stabilize the process of managing employees to ensure consistency across projects. The process has been spit in two functions, the sales a
Present day aid strategies and their effectiveness are subjected to fundamental reassessment. Major donors and international financial institutions are increasingly basing their aid and loans to the countries on the condition that recipient governments undertake reforms that ensure "good governance" of the allocated funds. Present study conducted in November and December 2007 in Zambia w
This research is based on the investigation of a Biosphere Reserve in the South of Mexico. It observes the Vision and Mission of the Biosphere Reserve Sian Ka’an in Quintana Roo Mexico based on the norms given by UNESCO’s Man And the Biosphere. It also tries to examine the Reserve’s opportunity for sustainability science to be a knowledge co-production and exchange platform. And its prospects to b
