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.
This thesis explores the possibility for (re)defining the relationship between humans and robots with conversational interfaces. It does so by looking at the creation process of a voice and text-based virtual assistant for tourists from the perspective of critical posthumanism and posthuman performativity. In a reflexive fashion, I analyze my involvement in a tech start-up, in order to argue that,
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
This thesis adds the role of the different types of proximity to the discussion on business development. It does so by aiming at start-ups that are currently located in business incubators in the city of Amsterdam, The Netherlands. Current research has focused on the output, effectiveness, diversity, and different types and roles of business incubators. It focuses on what happens within the incuba
This paper investigates the firm and transaction characteristics of PIPE issuers. Whereas previous empirical studies have been focused on the U.S. market, this paper focuses on the characteristics of the European market and also examines the importance of PIPEs as a source of financing and the impact of the institutional settings in key European countries. My findings show that many PIPE issuers a
Hållbar utveckling är ett begrepp som fått ökat genomslag i ljuset av den pågående globaliseringen. Även om det finns flera definitioner till begreppet så innebär hållbar utveckling i sak en strävan efter en varaktig och långsiktig ekonomiskt tillväxt utan att för den sakens skull försaka sociala resurser eller skada naturens ekosystem. Då en allmän uppfattning av globaliseringen är att den bidrarThe notion of sustainable development has gained increased interest due to the on-going process of globalisation. Sustainable development as a concept refers to lasting economic growth that does not deplete social resources or harm ecosystems. As there is a general perception that globalisation brings markets and society ever so close to each other, demands are being raised to hold market actors –
The focal point of this thesis is the peacebuilding environment in Nepal following the end of the civil war in 2006. A fieldwork investigation was conducted focusing on the perceptions of inhabitants of Kathmandu on peace and peacebuilding issues using semi-structured interviews. By investigating these perceptions the study seeks to answer three main questions: -How can the contrasting perspecti
Indonesia is a significant global player both in terms of economic performance and Carbon Dioxide (CO2) emissions. While its total Gross Domestic Product (GDP) and emissions are ranked high in global comparisons, both in terms of per capita measures have a relatively low ranking, suggesting that there is potentially more growth to come. Growth in Indonesia’s total emissions is being driven by econ
Tendons connect muscles to bone and consist of a complex structure of almost parallel collagen fibres embedded in a hydrated matrix. The mechanical behaviour of tendons is viscoelastic and highly non-linear. The Achilles tendon is the largest tendon in the body and it is essential for walking and jumping. It is the most frequently ruptured tendon in humans and today there is no consensus on what i
Spatial analysis, playing an essential role in data mining, is applied in a considerable number of fields. It is because of its broad applicability that dealing with the interdisciplinary issues is becoming more prevalent. It aims at exploring the underlying patterns of the data. In this project, we will employ the methodology that we utilize to tackle spatial problems to investigate how the cell
Synthesis of case studies is different from synthesis of purely quantitative studies, for example, in that sampling and analysis in primary studies have been carried out differently, and that primary results are of a different nature. The objective of this research is to identify what challenges should be considered when choosing and using a method for synthesis of case studies. We collected exper
The MAX IV facility currently under construction in Lund, Sweden will include a 1.5 GeV storage ring. To prevent head-tail instability, the negative natural chromaticities of the MAX IV 1.5 GeV storage ring have been corrected to positive values using sextupole gradients in the focusing quadrupoles along with dedicated sextupole magnets. To allow adjustment of the chromaticity correction, weak cor
One important task for the librarians at Physics and Astronomy Library at Lund University is to teach the students about the library and its resources. The traditional lectures and tours of the library just weren’t working. The library competes with many other introductory activities, such as general orientation, and social events. The aim of the Treasure Hunt is to present the library in a useful
Non wide-sense stationary (WSS) uncorrelated scatterering (US) fading processes are observed in vehicular communications. To estimate such a process under additive white Gaussian noise we use the local scattering function (LSF). In this paper we present an optimal parametrization of the multitaper-based LSF estimator. We do this by quantizing the mean square error (MSE). For that purpose we use th
