The polymer electrolyte membrane fuel cell (PEMFC) is an energy conversion device that uses hydrogen as fuel to produce electrical energy. The fuel cell is, however, very sensitive toward CO, thus, amounts over 10 ppm will poison the Pt-based anode part of the fuel cell. Preferential oxidation of carbon monoxide (CO-PROX) is considered to be the most efficient way of eliminating CO to such low con
Thesis purpose: to explore what influence consumer-brand relationships may have on consumers’ perceptions of personalized marketing and the personalization-privacy paradox. Methodology: to understand each of the respondents' different perceptions of the thesis’ purpose and research question, a relativist and social constructionist approach were applied. Theoretical perspective: in order to ful
Nuclear magnetic resonance spectroscopy is a technique for identifying molecular structures, compositions etc. and is widely used in many life science research fields. The purpose of this project is to synthesize PDMS microparticles with a magnetic susceptibility matching water, which makes them applicable for use in NMR of biological samples. The microparticles are intended to be used as a chroma
This design researched and explored the new way of solar light use and deploying, on efficiency and usability levels. Recent research has shown that the solar energy has a potential impact on people1, which accounts for one of the most of the available renewable energy on earth. In this research, I decided to look deeply into the appliance of solar light systems, to make solar energy accessible fo
The main purpose of this thesis is to investigate the digital skills that are important for accountants in order to stay relevant in the era of digitalization. In addition, the research has two sub-purposes. The first sub-purpose is to study the digitalization-related training. Secondly, the thesis aims to explore the accountants’ opinions on the challenges associated with the digitalization in th
The aim of this research was to investigate how employees working in a continuously changing organization perceive their work engagement and what experiences they have of organizational change and its impact on their work engagement. Previous research suggests that employees who maintain high levels of work engagement during organizational change will adapt better to it. Based on the theoretical f
Denna studies syfte var att undersöka skiftarbetares psykiska välbefinnande utifrån faktorerna socialt stöd från familj, vänner och andra speciella personer samt möjligheten att utföra ens fritidsaktiviteter. För att utforska detta genomfördes genom en enkätundersökning (n=32) där deltagarna bestod av skiftarbetare som arbetar olika slags skiftscheman på ett industriföretag i Sverige. Enkäten bestThe aim of this study was to investigate the mental well-being of shift workers based on the factors of social support from family, friends and significant others, and the possibility to participate in one’s leisure activities. A survey was conducted (n=32), and the participants were shift workers, working different types of shift schedules, at a Swedish industrial company. The survey was construc
Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. The availability of multi-source data, and advanced machine learning algorithms in Google Earth Engine (GEE) offers excellent opportunities to map wetlands on a country-wide scale. Th
Cutting carbon emission from road transports worldwide is a key component in limiting global warming, and electrification is one of the most likely automotive technologies to achieve this goal. Therefore, Elonroad is developing an electric road system that will allow its users to charge while driving. This allows greater range and a reduction in battery sizes. This master thesis is therefore aimin
Med allt större displayer i bilar och med en mer komplex funktionalitet på dessa, har förardistraktion blivit ett växande problem. I detta arbetet studerades detta problem och funktionalitet för att minska antalet interaktioner i mediaspelaren för att starta musik implementerades. Genom användar-testande påvisades att med ett användarvänligt och smart användargränssnitt kan detta uppnås.This project covers the increasingly growing problem of in-car driver distraction due to infotainment systems. The purpose was to understand this topic and variables, like size and user flows, that lead to distraction and then implement a solution in Spotify ́s Apple CarPlay application. This to combat this problem by providing the user with greater usability in terms of starting music playback. A
Fitting a model to a time-dependent ensemble average is a process repeated frequently throughout biophysics. A selected ensemble-averaged observable (⟨y(t)⟩) for a given system can be predicted through the use of an estimated ensemble average, where the estimated ensemble average is created via simulated or experimental data sets. Fitting a model to this estimated ensemble average allows for estim
Staphylococcus aureus är en kommensal bakterie, vars främsta nisch i människokroppen är huden och näsan. Det är också en patogen förmögen att orsaka ett stort antal infektioner, bland annat matförgiftning, infekterade sår men också allvarligare infektioner som blodförgiftning och hjärtmuskelinflammation. Meticillin-resistenta Staphylococcus aureus (MRSA) är resistenta mot praktiskt taget alla ß-laStaphylococcus aureus is a human commensal bacterium, living primarily on the skin and in the nose. It is also a pathogen able to cause a wide range of diseases, including food poisoning, infection of wounds but also more serious infections such as bacteremia and endocarditis. Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to virtually every ß-lactam antibiotic, making infections
Based on the Spain’s annual and quarterly time series from 1980 to 2020, this paper presents the first case study on the dynamic effects of fiscal consolidation episodes on income distribution and the mechanisms driving the specific dynamics of the distribution. By estimating impulse response functions via Local Projections by Jordà (2005), I find supportive evidence of the increase in income ineq
Sedan lagen om klimatdeklaration av byggnader trädde i kraft 2022-01-01 måste byggherren lämna in en klimatdeklaration som redovisar den färdiga byggnadens klimatavtryck under delar av dess livscykel för att få slutbesked. Lagkravet medför att aktörer involverade i nybyggnation av flera typer av byggnader behöver rutiner för hur nödvändig information ska sammanställas och hanteras. Detta examensar
