Background. Artificial neural networks have successfully been applied for automated interpretation of myocardial perfusion images. So far the networks have used data from the myocardial perfusion images only. The purpose of this study was to investigate whether the automated interpretation of myocardial perfusion images with the use of artificial neural networks was improved if clinical data were
To obtain full sky coverage, astronomical adaptive optics systemsrequire Na Sodium Beacons (SBs) (also referred to as Laser Guide Starsor LGSs) located at heights extending from 85 to 100 km. When viewed atthe edge of large telescopes these SBs appear elongated. For the Euro5050 meter aperture telescopes this elongation amounts to 6 to 9arcseconds when the laser is launched from a point on the tel
In the light of oil security concerns, the threat of climate change, and a desire to leverage competitive advantage for Sweden and its industries, the Swedish Government has announced a new policy target – the creation of the conditions necessary to break Sweden’s dependence on oil and fossil fuels by 2020. Notably, the Swedish Government stresses national opportunities and highlights two aspects
A dynamic model and simulation program describing the principles of a steam supply system for a paper dryer were developed. The dynamics of a cylinder and the paper sheet during an altered valve position were studied. The results showed that the dynamic course during a pressure increase is different from the course during a pressure decrease. A potential method for the determination of the heat tr
We have measured the interaction cross sections (σI) of 31–40Ar and 31–37Cl on carbon targets at energies of around 950 A MeV. The effective matter radii for these nuclei were deduced by a Glauber-model analysis. Combining our matter radii with measured charge radii for Ar isotopes, we could deduce the proton-skin thicknesses for the 32–40Ar isotopes, which were found to increase monotonically wit
I here propose a modification of the English butterfly census method (Pollard 1977) for studies of large areas with a relatively low density of butterflies. The transect line should not be more than 10 m from any point in open terrain and open forests, but only 5 m from sunny edges and patches with a high density of flowers. The transect line is adjusted between visits to most intensively cover si
Popular Abstract in Swedish Kartering av primärproduktion i Västrafrikanska Sahel genom användning av satellitdata. I avhandlingen har utvecklats en Light Use Efficency (LUE) modell som medger kartering av bruttoprimärproduktionen (GPP) exemplifierad i ett område i Västafrikanska Sahel. Modellen utnyttjar satellitbaserad månatlig Normalised Difference Vegetation Index (NDVI) tillsammans med andraA light Use Efficiency (LUE) model is developed that allows the mapping of total growing season Gross Primary Production (GPP) for the West African Sahel, using the Normalized Difference Vegetation Index (NDVI) together with other data. Image quality may be poor in monthly NDVI maximum value composites as shown by an improved geostatistical noise estimation technique. Quality may be improved by ot
New measurements of radiative lifetimes of four 3d65s levelsin Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in as
An alpha/beta barrel is predicted for the three-dimensional (3D) structure of Bacillus subtilis ferrochelatase. To arrive at this structure, the THREADER program was used to find possible homologous 3D structures and to predict the secondary structure for the ferrochelatase sequence. The secondary structure was fit by hand to the selected homologous 3D structure then the MODELLER program was used
The city of Stockholm has increased its number of surveillance cameras in public places the last few years in the name of crime prevention. However, as the number of cameras increases, how does this affect the people living in the city? This paper examines how surveillance cameras affect young women between the ages of 18-24 and their perception in different area around Sergels torg, T-Centralen a
I den här rapporten undersöks möjligheten för att tillverka och använda gjutmodeller tillverkade genom additiv tillverkning, i folkmun kallat 3D-printing. Först görs en grundläggande analys över hur modellerna tillverkas idag och vilka krav som ställs på modellen. Detta innefattar både rena material och hållfasthetskrav, men även mer svårdefinierade krav där man enbart kan resonera kring rimliga aIn this report the possibility for the manufacture and use of molding-patterns made through additive manufacturing methods, commonly called 3D-printing, is evaluated. First an analysis of how the patterns are currently being made and which demands that are put on them will be made. This includes more pure material and load demands, as well as more abstract and hard defined demands. After this the
Education has the potential to play a critical role in the sustainable transformation of society which is needed to limit the consequences of the multiple ecological crises society is facing. While this has been recognised internationally at least since 1992, not a lot has been done within the Danish educational system to address issues of climate change, biodiversity loss, and sustainability with
This case study investigates the involvement of private military companies (PMCs) in two African conflicts. Nigeria and Mozambique hired PMCs in 2014 and 2019 respectively to combat internal insurgencies. The paper aims to answer why these countries hired PMCs and if the PMCs were successful in combating the insurgencies. For the first question, the intensity of the insurgency and the state of the
The pressing issue of sustainability necessitates a broader collaboration span across all fields, such as finance and communication. Investments hold substantial power in the current sustainability reform, and it is therefore crucial that they not only meet the escalating demands of society but also actively contribute to forging a better future. The financial industry continues to grapple with ne
Investor sentiment is an important research object in behavioral finance, and its analysis has been one of the hot topics in stock market research recently. As an abstract concept, investor sentiment needs to be visualized by the construction of the investor sentiment index. In 2006, Baker and Wurgler proposed the Baker & Wurgler (BW) index, which can reflect investor sentiment in the American
Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter". A significant challenge for LDMX is to efficiently veto rare photo-nuclear back
Geographic Information Systems (GIS) are a powerful tool for supporting disaster risk reduction (DRR). International agreements such as the Sendai Framework for Disaster Risk Reduction call on high-income countries and other partners to support lower-income countries in strengthening their DRR capacities. This thesis explores the experiences of stakeholders in strengthening GIS capacities for DRR
