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

Social media plays an increasingly important role in organizational communication and stakeholder relationship management. The last few years has seen a growing number of studies examining how big organizations utilize social media channels for stakeholder relationship cultivation. However, research so far has overlooked startup companies, which are new players in the market and have the most to g

Advances in crystal growth allow for precise control of crystal phase in semiconductor nanowires. The arising novel materials, like wurtzite gallium arsenide (wz-GaAs), are promising options for new and improved, mainly optoelectronic devices. To do this, however, intensive investigation into their electroninc band structure is needed. This can for example be achieved by optical spectroscopy like

Following evidence of overpricing in structured products, I develop a comprehensive framework for pricing Equity-linked notes (ELNs). My model, unlike previous research, accounts for both the bank's actual funding costs and counterparty credit risk. I also allow for Asian payoffs in the derivative part — a feature now standard in ELN issuances. Studying a sample of eight ELNs issued by a Swedi

Solzhenitsyn was a famous nationalist who clearly stated his stance in non-fiction literature. In this study his stance will be further investigated by searching for expression of nationalism in three of his earliest fiction. The three works are the two short stories One Day in the Life of Ivan Denisovich and Matryonas Home and the novel Cancer Ward. The analysis found that the nationalism of Sol

Planerad och genomförd skötsel av naturreservat i Hallands län: Uppfylls reservatens syfte? Skötsel av naturreservatsområden behövs för att bevara de värden som reservatet instiftats för att skydda. Om reservatens skötselplan inte följs kan det leda till att syftet med reservatens instiftande inte uppfylls och att värdena som ska skyddas påverkas negativt. Studien visar att avvikelser från reservThis study aims to evaluate the management of nature reserves in the county of Halland in Sweden, focusing on reserves in which the main form of vegetation is deciduous hardwood forests. The purpose is to evaluate and compare planned management according to nature reserve management plans with current field conditions in order to identify discrepancies and their potential causes, based on a case s

The microbial community in five commercial Pu-erh tea products and one Liu Bao Cha tea were investigated in this study with the aim to search for beneficial live bacteria. Three different treatments were applied for every tea; non-brewed, brewed with and without leaf filtration. The results showed microbial activity in all teas and particularly lactic acid bacteria (LAB), except in the Liu Bao Cha

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

Datorseende blir allt bättre, men med dess precision tillkommer en beräkningskostnad. Detta arbete undersöker hur man kan använda svagare men fler datorer, exempelvis kameror, för att implementera dagens kraftfulla algoritmer.This document describes the methods and results of our Master’s Thesis, car- ried out at Axis Communications AB. A central problem with deep neural networks is that they contain a large num- ber of parameters and heavy computations. To cope with this, our idea was to split the network into chunks large enough that they require their own core, yet small enough to not violate our memory constraints.

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

Startups. Why are the odds of surviving the initial stages so low? While the internet revolution has made it easier to start up, for example by democratizing investments through crowdfunding, the rate of success is still daunting. Why? Ultimately, the world is still being built by humans. That means a group effort is required. To realize this, leadership is an undeniably crucial element. Yet, not

The Council Directive 92/50/EEC of 18 June 1992 relating to the coordination of procedures for the award of public service contracts establishes shared rules and procedures for the award of public service contracts within the internal market. The directive defines the public service contract award criteria, contracting authorities are bound to apply. Purpose of this study is to demonstrate how leg

What if you could accomplish order by being lazy? The project is about the balance between order and disorder. Without any extra thought, sorting clothes to create a calm environment for both eye and mind. Häng & Släng is a clothing rack that yields order in the disorder of half-used clothes (not clean but not yet ready for laundry), without demanding effort. The sense of order is achieved by

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

Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. These two signals hav

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 superconductivity under doping in the famous cuprate compounds is believed to originate in the CuO2 planes. The mediator of pairing is generally accepted to be induced from electronic degrees of freedom. While many mechanisms, such as spin fluctuations, have been proposed throughout the years, little research has been carried out on the role of the retarded attraction due to electronic overscr
