Bränsleceller är ett intressant alternativ till förbränningsmotorer då bränsleceller har en högre effektivitet, är miljövänligare samt tystare. Bränslen som diesel, bensin samt det undersökta bränslet Jet A1, innehåller olika svårreagerade svavelföreningar. Problemet med bränslena är att de har ett relativt högt svavelinnehåll. Svavelföreningarna riskerar att förgifta katalysatorerna i de nedströLogistic fuels such as diesel and petrol, in which Jet A1 is included, are sulfur-containing fuels used for transports. The main problem with logistic fuels, when used in fuel cell (FC) applications, is their relatively high concentration of sulfur compounds. The sulfur compounds might poison the catalysts in all of the downstream processes, including the FC itself. Hydrodesulfurization (HDS) is

The relation between parenthood and market work is an established field of study in demography. This thesis specifically focuses on the relation between parenthood and unemployment, the involuntary absence of work, in a cross sectional study of nine western democracies. The studied countries are Canada, France, Germany, Italy, Poland, Spain, Sweden, the United Kingdom, and the United States. A sig

With increasing competition and noise level in the third sector, Germany’s non-profit organisations have to start considering alternative ways of how to be heard by their target audiences and how to raise funds for their projects. Additionally, with technological developments and the rise of Web 2.0 this becomes particularly challenging. Strategic planning of communication and public relations act

This project have been about creating an object that helps the user to fall asleep and wake up comfortably. Today a lot of people use their smart phones as their standard alarm clock. It is simple, practical and doesn’t take up much space in the bedroom. However the smart phone is not sufficient to create a pleasant wake-up experience. To achieve a pleasant morning a lot of people instead use Wake

This is an investigation where I describe and circle in the media person Yahya Hassan, the poet slash the rapper slash the politician, and his public persona in interviews, TV programs, books, song lyrics, Facebook, etc. The purpose is with use of Jon Helt Haarder´s concepts aesthetics of the threshold, feed-back loop and haunting, as well as Poul Behrendt´s concept the double contract, analyze Ha

The purpose of this thesis was to investigate the difference between Pre-emptive and the Preventive use of force in a low-intensity conflict to which the drone campaign is a critical part of. Northern Pakistan has borne the brunt of the U.S. led drone campaign, and the Obama administration has exponentially increased the number of strikes that continues to target armed non-state entities in the tr

The stochastic volatility (SV) model is an alternative to GARCH models to model time varying volatility. In this thesis the basic stochastic volatility model and three different estimation methods are described---namely, Bayesian Markov chain Monte Carlo (MCMC) methods, quasi maximum-likelihood (QML) and generalized method of moments (GMM). To compare these estimation methods a large scale simul

This thesis seeks to examine the effect of food shortages on marital fertility in Malawi for the period of 1987-2009. Malawi provides an interesting case for studying this relationship, since the country has experienced many instances of food shortages in the studied period. The study was done by using the 2004 and 2010 Demographic and Health Survey for Malawi to utilise the retrospective data ava

Previous studies have entertained the prospect of having 3D models substitute for their dry bone originals in osteological analysis. The objective of this study was to contribute to qualifying to what extent this may be possible given current technology. To this purpose, rather than choosing just a quantitative and purely technical method for evaluating models, as has been the norm in previous stu

The blogosphere recently experiences an increasing attention by PR practice which engages in blogger relations to target bloggers as influential online gate-keepers. Bloggers thereby are given numerous possibilities to make use of their authenticity and credibility, and endorse brands through collaborations with PR. This study explores the established discipline of blogger relations in German PR a

Arbetet undersöker utvalda råvarufutres möjlighet att genom en cross-hedge prissäkra Dried Distillers Grain with Solubles (DDGS) som är en biprodukt från etanoltillverkning. Processen för att finna den bästa cross-hedgen sker genom OLS, ECM, VECM och MIDAS regressioner med både in sample estimeringar och out of sample prognostiseringar. Regressionerna använder börshandlade råvarufutures och säljpr

Since good cameras are becoming cheaper and embedded systems are getting more powerful, using cameras as the only sensor is getting more popular for visual navigation of robots. By using a robot to explore a flat surface a map can be gradually generated using the images taken by a downward looking camera. The thesis focus lies primarily on offline map building, where complete datasets are first ga

This thesis discusses whether wage convergence has taken place between six countries in the Association of the Southeast Asian Nation (ASEAN) from the time between 2000 and 2014. The countries included are Singapore, Indonesia, Malaysia, Philippines, Thailand and Vietnam. Following the approach by Stehrer and Wörz (2003), a fixed-effects model which uses initial wage gap to a reference country (th

Molecular data have offered new opportunities to resolve phylogenies especially in highly diverse and species-rich groups. The resolution of evolutionary relationships within Lepidoptera have progressed with the development of molecular methods. New species and genera are regularly described for the recently studied noctuoid moth subfamily Nolinae. Because of the limits of morphological characters

A responsible and sustainable water resources management is important. It is also crucial to take the presence of watercourses into account during design of hydraulic structures such as small dams and bridges. Doing this requires knowledge of estimates of annual streamflow and extreme flows to be used for design purposes. This study is divided into two parts, both focusing on the departments of Sa

According to the Environmental Protection Agency (2016) food production has a big impact on the climate, and a big part of the food gets wasted as garbage. About 91% of the food that the stores waste is still eatable (Naturvårdsverket, 2014). The government has set a goal to reduce the food waste with 20% until 2020 in comparison to 2010. In present days there’s a lot of research on how to maintai

In an uncertain future, flexibility and ability to adapt are recognized as important factors in avoiding errors, but also discover new ways of handling urban problems. This thesis examines how standardized wooden modules can be used to modify, manipulate and reinvent public space. It also investigates how flexibility in design could help to involve communities and individuals in reshaping and recy
