Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface of arbitrary material, ie the radome, is analyzed. The transformation is based on a full vector surface integral representation that relate
This thesis aims to explore the possibility of using deep learning techniques to mine opinions on Twitter, with the objective to predict the political opinion distribution in Sweden. Different methods of gathering and annotating training data are evaluated to achieve accurate and reliable predictions. The models are quite successful at predicting test data, achieving F1-scores in the range of 70 %
Många individer upplever höga stressnivåer på arbetsplatsen. Denna uppsats avser att utforska sambandet mellan olika aspekter som påverkar arbetsrelaterad stress i organisationer. Studien undersöker sambandet mellan fem individuella variabler: identitetshot, rädsla för negativ evaluering, självmedkänsla, arbetsposition och genus. I denna studie antas identitetshot och rädsla för negativ evalueringMany individuals experience high levels of stress at work. This paper aims to explore the relationship between elements that could generate and reduce levels of stress in work organizations. Specifically, the current research looks at the relationship of five individual difference variables: identity threat, fear of negative evaluation, self-compassion, work position, and gender. Identity threat a
Uppmärksamhetsbias har föreslagits vara involverat i både utveckling och vidmakthållande av tvångs- och ångestsyndrom. Befintlig forskning har emellertid genererat motsägelsefulla resultat och forskning avseende barn och ungdomar är begränsad, särskilt relaterat till tvångssyndrom. Vidare finns det ingen studie där uppmärksamhetsbias har undersökts i relation till Core Dimension Modellen (SummerfeBiased attentional processes have been implicated in the development and maintenance of anxiety disorders (ADs) and obsessive-compulsive disorder (OCD). However, existing research has yielded inconsistent results and there is limited research with samples of children and adolescents, especially in relation to OCD. Further, there is no study examining attentional bias connected to the Core Dimensio
A study is made of the multiplicities of the eigenvalues of the Laplace operator in the unit disc with Neumann boundary conditions. Our result is that all eigenvalues are simple or double, a result which is well-known if one instead considers Dirichlet boundary conditions. The result is proved by using some properties of Bessel functions. We also give an application to standing water waves in a cy
Under an action research paradigm, this thesis project explores the business potential of an environmental strategy and assesses the formulation of such a strategy implemented by an automotive original equipment manufacturer. Because of the heterogeneous nature of a company’s approach to environmental issues due to inter alia managerial conducts and company culture, this article provides an in-dep
A hallmark of adult hematopoiesis is the continuous replacement of blood cells with limited lifespans. While active hematopoietic stem cell (HSC) contribution to multilineage hematopoiesis is the foundation of clinical HSC transplantation, recent reports have questioned the physiological contribution of HSCs to normal/steady-state adult hematopoiesis. Here, we use inducible lineage tracing from ge
In this paper we consider scattering resonance computations in optics when the resonators consist of frequency dependent and lossy materials, such as metals at optical frequencies. The proposed computational approach combines a novel hp-FEM strategy, based on dispersion analysis for complex frequencies, with a fast implementation of the nonlinear eigenvalue solver NLEIGS. Numerical computations il
We study electromagnetic wave propagation in a periodic and frequency dependent material characterized by a space- and frequency-dependent complex-valued permittivity. The spectral parameter relates to the time-frequency, leading to spectral analysis of a holomorphic operator-valued function. We apply the Floquet transform and show for a fixed quasi-momentum that the resulting family of spectral p
This Master’s Thesis is the result of the collaboration between The Technical Faculty of Lund University and TÜV NORD Sweden AB. Focus has been directed towards the nuclear industry where this thesis is one of several other Master’s Theses regarding the dynamic modeling of a swing check valve. It is necessary for the nuclear industry to be able to model flow transients which involve the dynamic b
The purposes of this thesis is study the European Court of Justice from a non legal perspective and investigate the courts possibility to advance its own preferred goals rather that of the member states in cases of non-compliance. Drawing on general principal-agent theory I construct a model from which I derive certain hypothesis mainly about under what circumstances we should expect the Court to
The Republic of the Marshall Islands is nation consisting of small coral atolls located in Pacific Ocean. It is a nation currently listed as a developing country according to the Organization for Economic Co-operation and Development. The Marshall Islands have through history been colonized by Spain, Germany and Japan, and was later during the World War II claimed by the United States. The current

The most commonly used animal model for rheumatoid arthritis (RA) is collagen-induced arthritis (CIA), induced by immunization with type II collagen (CII), a cartilage restricted protein. In this work we show that type XI collagen (CXI), which is a minor component in cartilage, induces a different form of erosive and chronic relapsing polyarthritis in rats. Using a series of inbred rat strains inv
The aim of this study was to evaluate the efficacy and toxicity of paclitaxel given at the same dose intensity and administered weekly (arm A) or every 3 weeks (arm B), and to assess the safety of intravenous steroids versus standard peroral premedication. Two hundred and eight patients with advanced ovarian cancer previously treated with no more than one platinum-containing regimen were randomize
