Image quality metrics are used to evaluate the percieved quality of processed images. Differences in hardware between graphics processors contribute to noise during quality evaluation. In this masters thesis paper we train and evaluate neural networks as metrics to evaluate GPU rendering quality. The neural networks can successfully ignore the rendering noise that occurs when the test and referenc
Syftet med den här uppsatsen är att ge en bild av hur lärare upplever att kunskapskraven i svenska på gymnasienivå fungerar som arbetsredskap i deras dagliga arbete. Med lärares dagliga arbete menas planering, bedömning och betygssättning utifrån kunskapskraven. Lärarnas uppfattningar om kunskapskraven jämförs med deras upplevelser av betygskriterierna under Lpf 94. Dessutom jämförs lärarnas uppfaThe purpose of this study is to highlight upper secondary school teachers’ experiences of working with the national knowledge requirements in the Swedish subject. Teachers use national knowledge requirements as a tool both when they plan lessons and when they assess and grade students. The teachers’ experiences of the national knowledge requirements are compared to their opinions of the previous k
The aim of this study was to explore how social service workers discuss digitization and its impact on their role as professionals. This was done to obtain a deeper understanding of the challenges and opportunities that a digitization might entail. We have taken a qualitative approach to our study by interviewing eight social service workers, in two organizationally different social service office
The ability to navigate from breeding sites and wintering grounds has fascinated numerous avian studies examining the bird orientation performances. The migratory avian navigational toolbox consist of route- and map-based orientation, non-compass, vector and compass orientation. The compass orientation consist of celestial and geomagnetic cues, which are divided into the three main compasses known
Traditional mean-variance optimization of portfolios has received much criticism due to its inability to account for higher order moments and non-quadratic utility. In this thesis, the topic of portfolio optimization is studied using the Atkinson index with CRRA utility. We construct Atkinson-efficient portfolios using computer-generated data in Monte Carlo simulations, as well as using financial
The increasing concern on the present and future impact of climate change has raised the attention on the relationship between technology and the environment. The aim of this paper is to investigate the impact of green innovation on carbon emissions. Carbon dioxide (CO2) and Greenhouse Gas (GHG) emissions per capita are used as a proxy for environmental quality. Technological innovation is measure
The latest global financial crisis ignited the debate on whether the role of monetary policy's main objective, price stability, is enough to achieve financial stability. It also sparked an interest of new policy measures that directly targets the financial system, such as macroprudential policies. In this study, we empirically investigate how monetary and macroprudential policies interact to a
In recent years, the field of mass spectrometry (MS) has grown significantly, allowing for shotgun proteomic experiments to be used increasingly in biomarker discovery experiments. However, using standard methods of MS not all peptides present in a sample may be identified. To combat this, a procedure termed alignment, or match-between-runs, is used to propagate identifications from one run to ano
Denna rapport behandlar en brandteknisk riskvärdering av Göteborgs Stadsteatern, som ligger vid Götaplatsen i Göteborg. Rapporten skrivs som en del av kursen Brandteknisk Riskvärdering som ges det tredje året på Brandingenjörsprogrammet på Lunds Tekniska Högskola. Stadsteatern består av två delar, där Del 2 är en tillbyggnad till den gamla byggnaden som benämns som Del 1. Hela bygganden består av
Empathy is a phenomenon known by many definitions in the positive sense. The concept is mentioned as one of the three most important components within social work. At the same time, the concept of empathy is elusive and oftentimes difficult to pinpoint in the everyday social work practice. The aim of this study is to explore how social workers who work directly with vulnerable groups define and re
Mounting cameras on motorized objects has become possible in greater extent due to the emerging camera technology during the past few decades. This application could prove useful in several areas such as search and rescue operations, surveillance or even news monitoring. One hardship that this brings is the difficulty of keeping the camera unit stable while its setting is not. In the situations me
The link between income inequality and economic growth has been a popular topic in the empirical research literature in the past decades. Despite that, a consensus is yet to emerge. This paper analyzes the effect of income inequality on economic growth and the role of institutions in mitigating potentially negative effects using a panel of 48 countries in the time-period 1977-2009, including a mix
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
I denna rapport så har matsalar i fyra skolor observerats genom ett FAMM ( Five aspect meal model) perspektiv. Vegetabilisk kost har börjat prioriteras i olika kommuner i Skåne. Fördelarna med vegetarisk kost är flera, det är miljövänligare, hälsosammare och billigare än kött. Livsmedelsverket rekommenderar att öka andelen vegetabilier och minska andelen kött samt att lunchen bör ha minst ett veg
This research has been conducted through a single case study by applying a qualitative research approach on how a university context shapes the way entrepreneurs learn in an incubator. The data was collected through semi-structured interviews and analyzed according to Gioia, Corley and Hamilton (2012). Literature regarding Entrepreneurial Learning through an Experiential and Social Learning Theory
Automated Twitter accounts, or Twitter bots, have gained increased attention lately. In particular, a novel type of bot, so called social bots, are piquing peoples’ interest, as these bots have recently been involved in a number of political events. Most of the previous work on how to detect bots has not distinguished between such novel bot types, and other, less sophisticated ones. Instead, they
De svenska tillverkarna av ultralätta mikroflygplan, Blackwing Sweden AB, har lämnat en förfrågan gällande uppdatering av den justerbara mekanismen tillhörande roderpedal-systemet i flygplansmodellen BW600RG. Det nuvarande manuella systemet anses bristfälligt sett till den icke ergonomiska justeringsprocessen som för övrigt kräver att flygplanet är stationärt. Målet med detta projekt var att framfThe Swedish ultralight aircraft manufacturer, Blackwing Sweden AB, has requested a reinvention of their adjustable mechanism for the rudder pedal system in the BW600RG aircraft. The current manual system is insufficient in terms of a non-ergonomic adjustment process which requires for the aircraft to be stationary. The ambition of this project was to deliver a concept covering a fully automated ad
This master thesis examines the valuation of FinTech and Dot-Com companies by looking at the underpricing level of initial public offerings (IPOs) and the abnormal returns during the period surrounding the announcement date of merger and acquisitions (M&As). The sample consists of 234 IPO’s observations from 1995-2019 and 58 M&A’s deals from 2000-2019. The results suggest that the underpri
Previous research shows that gambling addiction receives less attention in Social services compared with substance abuse. The aim of the study was to compare the child-welfare officer’s view on problem for the child and also on support and assistance for children who grow up in families where parents are compulsive gamblers than in families where parents have a substance abuse (in this paper it wi
