This thesis investigates using machine learning for estimating the infrared-to-visible light ratio (qIR) in images, which is used for day/night synchronization in surveillance cameras. Three different models were developed, namely a regression multilayer perceptron (RMLP), a regression-by-classification MLP (RbC MLP), as well as a gradient-boosted decision tree (GBDT). Using an internal dataset co
Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. Utilizing data collected from a pressure sensor inside the pipette could be a way of automatically verifying different aspects related to the p
This project targeted automating production steps where stud bolts are welded on a heat exchanger within allowed perpendicularity and position requirements. Until now, this has been a manual process where an operator uses steel templates to position the bolts in the right place and manual welding guns to weld the bolts. The scope of this project is to create a digital model of a robot cell to calc
The aim of this paper is to evaluate a machine learning technique, Random Forest, to predict default rates for banks in the United States. This study extends the findings of a Random Forest model first introduced by Petropoulos et al. (2017) by extending their model by evaluating a longer sample period and adding macroeconomic variables to analyze how current market conditions impact the predictio
Analogisk överföring undersöktes hos förskolebarn (24 månader till 55 månader) med en faktoriell tvärsnittsdesign. Analogisk överföring testades direkt efter inlärning eller ett dygn senare med en visuo-spatial uppgift. Vidare testades de kognitiva förmågorna arbetsminne, inhibering, självreglering och verbal intelligens. Studiens hypoteser var att fler barn skulle klara den direkta överföringen äAnalogical transfer was studied in preschool children (24 months to 55 months) with a factorial cross sectional design. Analogical transfer was tested directly after learning and one day later, using a visuospatial task. The cognitive abilities working memory, inhibition, self-regulation and verbal intelligence was assessed. The hypotheses were that more children would pass the direct condition th
Studien undersöker familjeterapistudenters upplevelser av familjerekonstruktion. Syftet med studien är att få en fördjupad förståelse för familjerekonstruktion med hjälp av reflektioner och upplevelser från studenter på psykoterapeutprogrammet, inför sin framtida profession. Studien utgår från semistrukturerade intervjuer med frågor fokuserade på fyra teman; grupprocess, tidigare kunskap om familThe study examines the subjective experiences of post-graduate students in family therapy training after family reconstruction. The intention of the study is to gain a deeper understanding of the possible effects of the family reconstruction process on students during training as well as in their work as family therapists. The survey is based on semi-structured interviews. The data was interpreted

Syfte: Syftet med uppsatsen är att undersöka hur allsvenska fotbollsföreningar hanterar den balansgång som finns mellan sportslig och ekonomisk framgång. Vidare har vi för avsikt att försöka utreda hur sportslig och ekonomisk framgång kan skapa förutsättningar för att föreningarna ska nå fortsatta framgångar i framtiden. Metod: En kvalitativ undersökning genomfördes och semi-strukturerade intervjPurpose: The purpose of this thesis is to examine how football associations from the Swedish football league Allsvenskan manage the balance between sporting and financial success. Furthermore, we intend to investigate how the sporting and financial success can create conditions for continued success in the future. Methodology: A qualitative study was made and semi-structured interviews in person
This essay aims to investigate how Amnesty International handles the so called peace versus justice dilemma in post-conflict societies. This is done by studying a number of Amnesty publications published between 1996 and 2000, concerning various aspects of justice within the peacebuilding-process in Sierra Leone. More concretely, what is studied is whether Amnesty tends to prefer judicial (trials)
Avrinningsområdet Mundaú har sitt ursprung i den Brasilianska delstaten Pernambuco och rinner i sydöstlig riktning mot Mundaúlagunen längs Atlantkusten tillhörande delstaten Alagoas. Området faller under nationell jurisdiktion, är relativt oreglerat och erfar både översvämningar och torrperioder. Modellering av avrinningsområdets hydrologi kan ge en fördjupad förståelse av dessa händelser och hur The relatively unregulated, union domain Mundaú river basin, upper reaches originating in the Brazilian state of Pernambuco and flowing southeast to the Mundaú Lagoon along the Alagoas state’s Atlantic coast, suffers from both flooding and drought. Modeling the basin’s hydrology can lead to a deeper understanding of these events, and how changes within the basin can affect its hydrology. This stud
This study is about collaboration between the probation service and the social services. The aim of this study is to examine how professionals within each organization work together regarding clients that have been convicted to a probation sentence and suffers from an addiction. The aim was also to examine how the employees’ from both organizations, experience this collaboration. The study relies
The aim of this essay is to study if the Chicago Board of Options Exchange’s volatility index VIX can be used as an indicator on the stock market, and if an investor can make a profit on portfolios by using a volatility strategy based on VIX. The study is based on nine volatility strategies that are tested on four different portfolios containing stocks from Mega Cap, Large Cap, Mid Cap and Small C
Previous research has focused on the correlation between CSR and returns, whilst considerably less efforts have been undertaken to investigate whether CSR affects a company’s valuation. Therefore this paper focus on investigating the correlation between these two variables. This is done by comparing valuation multiples of constructed indices consisting of bad and socially responsible companies to
The Kyoto target for Romania was to reduce its carbon dioxide emissions by 8 % from the 1989 levels. The 1989 emissions were around 260 million tones. In 2000 the net CO2 emission - some 125 million tones - were 54% of the net CO2 emission in the reference year -1989, leaving some 115 million tones as a reserve or as a tradable resource to other countries that can not met their Kyoto targets. Assu
A comparative study on the bis(functionalization) of the Troger's base core by aromatic and heteroaromatic groups using palladium-catalyzed cross-coupling reactions is presented. Three different reactions, the Suzuki, Stille, and Negishi couplings, were investigated using Troger's base analogues equally substituted in the 2,8-positions with (HO)(2)B, Bu3Sn and ZnCl groups, respectively, as the met

The current study evaluates the factor structure of the Disgust Scale-Revised (DS-R) in eight countries: Australia, Brazil, Germany, Italy, Japan, the Netherlands, Sweden, and the United States (N = 2,606). Confirmatory factor analysis is used to compare two different models of the DS-R and to investigate the invariance of the factor structure of the DS-R across countries and gender. A three-facto
