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

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

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

The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization workshop in 1999. The initial goals were (1) to propose a new allergic rhinitis classification, (2) to promote the concept of multi-morbidity in asthma and rhinitis and (3) to develop guidelines with all stakeholders that could be used globally for all countries and populations. ARIA - dis

The macula of the human retina contains high amounts of the xanthophyll carotenoids lutein and zeaxanthin [a mixture of (3R,3′R)-zeaxanthin and (3R,3′S-meso)-zeaxanthin]. Recently, it was shown that the uptake and the stabilization of zeaxanthin and lutein into the retina are likely to be mediated by specific xanthophyll-binding proteins (XBP). Here, we have used femtosecond pump–probe spectroscop

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

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

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

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

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
