Heterogena katalysatorer för användning i bränslecellssystem har undersökts baserat på aktiv fas och tillverkningsmetoder för granulat- och monolitkatalysatorer. Katalysatorerna tillverkades genom att använda θ – aluminiumoxid som bärare, dopad med lantan och cerium, där den aktiva fasen bestod av ädelmetall X och nickel i varierande halter. Analys gjordes genom att låta en blandning av vattenångaHeterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. Analy

This thesis studies demonstrations in a game theoretic framework. In the model designed, demonstrations are explored as signals from different types of agents who pursue a redistribution in their society. The types of agents depend on their likelihood to achieve a “large” demonstration and therefore a franchise extension. The ones in power cannot distinguish between the types of agents, thus it is

Quantification through image analysis is used in a multitude of fields, and often requires algorithms tailored to the specific task and object that needs to be quantified. The need for flexibility means that such segmentation algorithms are quickly becoming outdated with the advent of convolutional neural networks, which can be trained to fit the specific requirements of the user. One of the field

Under våren 2020 har många blivit påverkade av det så kallade coronaviruset, Covid19. Viruset har eskalerat i hög takt och utvecklats till en pandemi som påverkat världsekonomin och samtliga branscher. Dagligvaruhandeln har framförallt blivit påverkad och diskussioner har väckts kring konsumenters agerande i samband med den höga försäljningsökningen. Konsumtion under kriser har i tidigare forsknin

The purpose of this study is to contribute to the limited literature on sustainable consumption in Vietnam with a focus on the young urban consumer. Sustainable consumption is an important area to focus on as Vietnam is an emerging economy with a young population where consumption is increasing and where the young and fast-growing labor market underpins their economic prosperity. Vietnam is also e

Denna uppsats är ett kulturanalytiskt forskningsprojekt som syftar till att förstå hur sociala och kulturella processer i olika rum i staden bidrar till upplevelsen av ofrivillig ensamhet. Uppsatsen undersöker den ofrivilliga ensamheten i olika skalor i staden, från bostaden, kvarteret, ut i bostadsområdet och vidare ut i staden. Detta uppnås genom att använda ett fenomenologiskt ramverk som analyThis thesis is a cultural analytical research project that aims to understand how social and cultural processes in spaces within the city contribute to the experience of loneliness. The thesis explores loneliness at different layers of the city, from housing, the neighbourhood, to the district and the wider city scale. This is achieved by using a phenomenological framework that analyses the indivi

Abstract The Six-Day War of 1967 and the Yom Kippur War of 1973 are two of the most important military altercations of the Arab-Israeli conflict. Both wars were started by surprise attacks by either side. In 1967 Israel surprised the arab nations and in 1973 the arab nations surprised Israel. This essay is going to, both, analyse the deception and surprise performed in the wars separately and then

I ett nytt och mer pluralistiskt medielandskap, med plattare strukturer, har en ny typ av informationsanvändning växt fram. Denna verkar genom att skapa osäkerhet och därigenom möjlighet till implausible deniability snarare än den plausible deniability som tidigare varit vanlig och intimt förknippad med covert action. På detta område har den ryska staten ansetts vara en föregångare men mindre är k

Den här studien undersöker huruvida medierapporteringen av visselblåsare påverkar vilket fokus media väljer att lägga i sin rapportering: på visselblåsaren eller den information som har läckts. Analysen genomfördes med en narrativ textanalys där totalt sex stycken artiklar om Mark Felt, personen bakom Watergate-visselblåsaren Deep Throat, och Chelsea Manning. Resultatet visar att det finns en skil

Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. Shallow geothermal energy systems can thus be used to provide heating and cooling with or without heat pumps. This study aims to

As institutional racism and the underrepresentation of BAME have become world-wide central issues, the question of equal opportunities for upward mobility in the labour market and social mobility for this particular community are at the forefront, including the UK context. Evidence suggests that BAME have unequal access to opportunities for career progression in the workplace and that upward mobil

Since the 1980s emotion regulation (ER) has been more in focus for its connection to psychopathology, such as in anxiety-, mood- and substance disorders. Walter et al. (2009) proposed that one possible explanation for an activation his team found after a certain emotion regulation strategy (ERS) being employed, i.e. detachment, could be the rebound effect as it has been described by Wegner, Schnei

The implementation of iris scan technology in the context of humanitarian financial assistance in UNHCR-run refugee camps raises an array of legal questions. While the collection and storage of biometrical data in other contexts is often accompanied by a critical discussion about data protection and privacy concerns, the use of such data in humanitarian settings is often left uncontested. The in-d

Following 9/11, an explosion of transnational counterterrorism regulations aimed at countering the financing of terrorism has been established. These have since had suffocating effects on aid delivery in areas where designated terrorist organizations are present, resulting in the denying of aid to the most vulnerable. Regardless, transnational regulations have only grown more assertive during the

The aim of the thesis is to explore how states react to international pressure and global governance in a global crisis. This will be examined by using a quantitative method approach to studying the impact of international climate agreements on the climate mitigation finances provided by Development Assistance Committee states. Additionally, it will also explore whether the impact of international

Community-based governance (CBG) has become a widely accepted concept for rural water provision in low and middle-income countries. However, it is being questioned if CBG has reached its limits due to numerous reports of the non-functionality of rural water systems. This study aims at understanding the role of intermediary organizations for CBG and how their relational character can improve rural

Title: The Exploring Digital Framework: A Comparative Case Study within the Swedish Manufacturing Industry Author: Daniel Ögren Supervisors: Carl-Johan Asplund (LTH), Jonathan Bergsteen (Triathlon Group), Fredrik Wadsten (Triathlon Group) Background: As new digital technologies and concepts arise, the inherent meaning of digitalization broadens. Consequently, companies experience increasing com

Lust is designed and dedicated to encouraging a healthier discussion about sex and masturbation by taking on a new generation of sex toys. A majority of us masturbate regularly but few consider it important to talk about in our close relationships. Today, pornography, in the absence of an open discussion, seems to be an unspoken source of education for young people. It is the leading moderator o

Energisystemet genomgår för närvarande en snabb transformation med allt mer förnybar elproduktion. Ett sätt genom vilket företag kan köpa förnybar el är genom långsiktiga elköpsavtal (Power Purchase Agreements, PPAs), i vilka de enas om ett fast pris och andra villkor med en projektutvecklare. För att bedöma ett rättvist fast pris av PPAn, så behöver först det framtida marknadspriset på el uppskatThe energy system is currently in a rapid transformation with increasingly growing renewable electricity production. One way through which companies can buy renewable electricity is through long - term corporate Power Purchase Agreements (PPAs), in which they agree on a fix price and other terms with a project developer. To determine a fair fix PPA price, the future electricity market price needs
