Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin
This master thesis in social anthropology, is based on fieldwork, conducted in the peruvian village Andamarca, in the region of Ayacucho, from February to April 2018. I have studied the special kind of folk music, called huayno, in order to establish its role in the local community. The inhabitants find themselves living in a vulnerable state, based on a violent history and political oppression. T
In recent years sustainable investment has increased enormously, and firms that are considered to have high social responsibility has gained interest from investors. However, if these firms have higher financial performance or not is still unclear, and researchers still have split opinions on the relationship. The purpose of this research is to analyze this relationship, with data collected from t
I den här uppsatsen undersöks generella effektiviseringar i svenska kommuner. Med generella effektiviseringar avses när förvaltningar eller verksamheter åläggs generella sparkrav utan att kraven på verksamhetens kvalitet eller vad den ska utföra sänks. Frågeställningarna har varit: • Med vilka argument har generella effektiviseringar genomförts av kommuner? • Hur är de kommunalt genomförda genere
Celiac disease is an autoimmune disease triggered by gluten intake. The disease has both a genetic component and an environmental component. Celiac disease is often associated with dysbiosis and lower diversity of the gut microbiota. In this study a group of 3-year-olds susceptible to celiac disease were enrolled in a double-blind placebo-controlled randomized trial using a combination of two prob
This paper exploits the adoption of Single Spine Pay Policy (SSPP) as a natural experiment to investigate the potency of wage policies in addressing the pay differentials between the public and private sector in Africa. The Government of Ghana in 2010, implemented the SSPP to tackle the long-standing wage gap between the public and private sector and consequently improve productivity in the public
Sökmotoroptimering (SEO) är ett sätt att arbeta på som förbättrar ens hemsidas ranking hos sökmotorer. Teorier om hur man ska jobba med det och varför man ska göra det har beskrivits i tidigare litteratur. Trots detta är det ett stort antal företag som väljer att inte arbeta med det. Denna uppsats syftar till att undersöka varför små och medelstora företag inte arbetar med SEO. Detta görs i en kom
As global temperatures rise, adverse health effects due to heat exposure are an increasingly pressing issue, particularly threatening to the health of elderly people. Mitigating these threats requires a dynamic climate adaptation system embedding a variety of measures. Ideally, such a system incorporates the coping strategies and experiences of the vulnerable themselves in a well-developed strateg
The automation of work tasks has been of high interest for over a century, where different technologies have been developed to serve this purpose. Robotic Process Automation (RPA) is one of these technologies, which automates the execution of monotonous and repetitive work tasks previously performed by humans. As a consequence, the employee whose job consists of these work tasks might perceive eff
Studiens syfte var att undersöka unga tjejers (16-17 år) upplevelser av sig själva och sin självkänsla. Detta undersöktes genom semistrukturerade intervjuer med åtta tjejer från en gymnasieskola. Materialet kodades och analyserades med Interpretative Phenomenological Analysis (IPA) som metodologisk ansats, vilket gav upphov till fyra olika huvudteman som beskriver fenomenet: att se sig själv utifrThe purpose of this study was to investigate young girls (age 16-17) experiences of themselves and their self-esteem. This was done by semi-structured interviews with eight girls from an upper secondary school in Sweden. The collected material was coded and analysed with Interpretative Phenomenological Analysis (IPA) as a methodological approach. This resulted in four main themes which describe th
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 uppfa
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
