I first got introduced to wireless power during another school pro- ject that resulted in a wireless charging case. In that project I con- ducted a lot of market and technology research about wireless charging and wireless power in general. During that project I got in contact with a Malmö based company called Nok9. They develope and produce test equipment for developers of wireless power de- v
Abstract Author: Jakob Rönnqvist Title: Värdegrundsarbete inom handikappomsorgen – en studie om medarbetares syn på värdegrundsarbete Supervisor: David Hoff In recent times, ethic related questions have come to play a major role within organiza-tions and corporations. The introduction to basic value work can be seen as a conse-quence of this process. Previous research indicates that basic value
The aviation sector is facing a massive change in terms of replacing the currently used fossil jet fuels (Jet A, JP5, etc.) with non-fossil jet fuels from sustainable feedstocks. This involves several challenges and, among them, we have the fundamental issue of current jet engines being developed for the existing fossil jet fuels. To facilitate such a transformation, we need to investigate the sen
Alternative jet fuels can be radically different from conventional fuels in composition, and the consequences of these differences are a subject of ongoing research. Numerical combustion simulations are vital to this research, and require chemical reaction mechanisms that accurately capture the chemical pathways of combustion. For turbulent combustion, these mechanisms must also be compact and eff
As global steel demand continues to rise, the steel industry faces increasing pressure to reduce its energy consumption. Conventional cooling is inefficient, and novel technologies have the potential to improve these processes. One promising approach is the use of pulsating flow to enhance heat transfer during cooling of hot steel plates. In this thesis Infrasonik’s infrasound cooling solution is
We present a batch method for recovering Euclidian camera motion from sparse image data. The main purpose of the algorithm is to recover the motion parameters using as much of the available information and as few computational steps as possible. The algorithm thus places itself in the gap between factorisation schemes, which make use of all available information in the initial recovery step, and s
A simplification of the laminin nomenclature is presented. Laminins are multidomain heterotrimers composed of alpha, beta and gamma chains. Previously, laminin trimers were numbered with Arabic numerals in the order discovered, that is laminins-1 to -5. We introduce a new identification system for a trimer using three Arabic numerals, based on the alpha, beta and gamma chain numbers. For example,
The thesis presents a numerical method developed by the author and its applications for computing the generated sound by an unsteady flow field and its propagation. The full equations of motion for compressible and unsteady flows describe both flow field and sound generation and propagation. It is assumed that the flow variables can be decomposed into semi-compressible / incompressible components
We report on the synthesis and characterization of fluorescent halogen substituted anthracene-bridge-aniline (ABA) supermolecules that undergo structural reorganization on photoexcitation to form transient complexes. The syntheses were achieved in high yields on a large scale and the molecular structures were confirmed by single crystal X-ray diffraction. The photophysics of the ABA supermolecules

The aim of this study is to examine what differences there are in expressed values on the authoritarian-liberal scale of European right-wing parties in social issues. The point is to highlight possible differences between European populist right-wing parties and traditional right-wing parties. The method of the study is a descriptive idea analysis. This means that suggestions presented by the exam
The aim of this study was to assess the rate of clinical progression to early and late stages of human immunodeficiency virus-2 (HIV-2) infection. CD4 cell counts and other potential prognostic markers for disease progression were also evaluated. In January 1990 an open prospective cohort of police officers in Guinea-Bissau was initiated with yearly serological and clinical follow-up. Follow-up en
We analyze how the interaction between two hydrophobic surfaces in water depends on the amount of dissolved gas. At equilibrium there is, for a truly hydrophobic surface with contact angle theta > 90degrees, a long range attractive force. The attraction is due to the formation of a gaseous film between the surfaces. For a completely degassed sample the gas consists of water vapor and the range of
Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. Samtidigt möjliggör ökad beräkningskraft i moderna datorkluster att detaljerade simuleringar kan utföras för att stuClimate change is affecting our world and a more sustainable society is needed. The aviation industry is in need of change but aero-engines are very complex and take time to develop. Thermoacoustic instabilities have the power to destroy an engine, but also to reduce the environmental impact. At the same time, increasing computational power allows detailed simulations to be executed in order to st
Here we present the integrated design, high-fidelity simulation, and virtual emissioncertification of a medium-range aero-engine combustor developed within the EU-funded MYTHOS project. The objective is to establish a physics-based framework capable of predicting combustor behavior for both conventional fuels and emerging Sustainable Aviation Fuels (SAF). Starting from a 0D thermodynamic cycle, a
Development of a new reduced chemical kinetic reaction mechanism for kerosene-air combustion is presented. The new mechanism uses a modular based development technique and is a further development on previously presented kerosene-air mechanisms. The new mechanism consists of 30 species and 77 irreversible reactions and is developed to accurate reproduce key flame parameters yet being small enough
