Many models beyond the Standard Model that predict the existence of multiple Higgs bosons. In general, some of these additional Higgs bosons could be quasi-degenerate in mass either to each other or to the observed 125 GeV Higgs boson. The goal of this thesis is to study under which circumstances we can resolve such Higgs bosons. We first make the simplifying assumption that the observed and predi

To protect the rights of the individual or to ensure legal certainty where witnesses should not be affected by reprisals is the question raised in the debate for anonymous witnesses. Therefore, is this essay based on understanding how a police commissioner and a defense lawyer's legal consciousness can be understood based on the topic of anonymous witnesses. The main problem within the debate

A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. Analog discrete-time filters have gained a lot of traction lately, mainly due to their promising architecture, achieving baseband filtering,

Eftersom världen fortsätter att se en ökning av koldioxidutsläpp, är åtgärder för att minska människans negativa miljöpåverkan av största vikt. För att kunna konkurrera med flygindustrin föreslår Trafikverket en omfattande utökning av det existerande järnvägsnätverket. Detta inkluderar byggnation av höghastighetsjärnvägar, som skall koppla samman Sveriges storstäder. Sådana planer innefattar även As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. This includes the construction of high speed railroads connecting the largest urban areas

One of the main challenge’s society faces today is climate change caused by CO2 due to the de-pendence on fossil fuels. To combat the increasing CO2 levels there is a need to develop renewable fuels. One such fuel could potentially be derived from lignin. In this thesis, lignin derived from a pulp and paper mill was first treated and cleaned. The lignin was then processed by catalytic hydroproces

As Muslim communities have become more permanently established in Western European societies, debates around the public practice of Islam in these societies have become more prevalent, while the “global war on terror” rhetoric has aided the construction of Muslim minorities into “Others” along lines of religious and cultural differences. Based on theories of minority participation in the public sp

The aim of this collaboration, between the division of Thermal Power Engineering and Lunds Energi AB, is to investigate the possibilities of training artificial neural networks (ANNs) with power plant operational data. For this purpose operational data from Lunds Energi's gas turbine GT10B with heat recovery unit (HRU) will be used. Furthermore a model with user interface is created to dem

This study examines Poland’s adhesion to the EU and the structural effects this has had on Polish exports which has grown significantly during the last two decades. The purpose is to analyze whether this growth has been the result of intensified or diversified Polish exports. In order to seize the structural effects this study decomposes the Polish trade flows into an extensive margin (new flows)

The treatment of sewage sludge is often a neglected part of wastewater treatment operation in developing countries. It is generally perceived as an additional operational cost and its importance for an adequate sanitation system is not fully recognized. Therefore, the production of sewage sludge represents a risk of human health and the environment due to the potential of spreading pathogens. In M

Purpose: The main purpose is to investigate a multinational corporation subsidiary established in a developing country and their current as well as their future work concerning CSR. Method: To carry out our research, we performed a theoretical study as well as an empirical. Our empirical study consisted of a qualitative case study performed at the company stated above. We used semi-structured inte

På grund av begränsningar i existerade biometriska matchningsalgorithmer är det i dagsläget en mycket svår uppgift att utföra pålitlig identifiering med en stor mängd registrerade användare. Detta arbete undersöker om det är möjligt att utföra en pålitlig identifiering genom att först reducera antalet möjliga kandidater genom att använda tillgänglig information i en filtreringsprocess. Detta arbeThe aim of this thesis is to investigate the possibility of enabling biometric identification given a large number of enrolled users. This area is relatively unexplored compared to biometric authentication where a fingerprint template is compared against just a few number of templates. The selected approach is to use auxiliary information available during an identification. This information will b

I och med min utbildning till lärare i musik- och svenska som andraspråk vill jag låta dessa ämnesområden sammanfläta i mitt examensarbete. I och med den flyktingström som påverkat hela vårt land har skolsituationen i Sverige förändrats. Antalet nyanlända elever i skolan har ökat och många av dem ska få undervisning i musik. Detta är ett uppdrag som musiklärare inte varit beredda på. Därför är syfIn my education, to be a teacher in music and Swedish as a second language, I want these subjects intertwine in my degree project. With increase of refugees in our country, the school situation has changed. The number of new arrivals in school has increased and many of them will be taught in music. This is an assignment that music teacher has not been prepared for. Therefore, the aim of the study

Hur låter musiken som spelas av atomer? Även om de inte kan sjunga så kan atomer – de små byggstenarna som bygger världen – interagera starkt med laserljus och då skapa kortvariga ljusblixtar som är lika harmoniska som musik. Att förstå hur laserljus och ljusblixtar är relaterade är genom deras interaktioner med atomer. Detta kommer att hjälpa oss att följa aktiviteten som händer så snabbt att denLight-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. In particular, one of the few tools for ultrafast spectroscopy are coherent attosecond XUV pulses: light pulses in the extreme ultraviolet range (XUV) whose typical duration

Vi lever idag i en tid av fundamental osäkerhet och striden får vi inte sällan höra står mellan de som går en osäker framtid till mötes och de som nostalgiskt blickar tillbaka. I Vellinge möter vi de som med vemod ser sin ort förändras till vad den inte tycks ha varit förut, liksom de som betraktar ortens utveckling i starkt positiva ordalag. Men vi möter också personer med olika materiella förutsThe following thesis examines two responses to processes of social change within the small town of Vellinge in the province of Scania, Sweden. The experiences of change within the town appear in the guise of two contradicting narratives – one of the town’s progress and the other of its decline – which I aim to approximate from nine in-depth interviews with eight inhabitants conducted in two cycles

Information security is only as strong as the weakest link. Although the technical, externally oriented efforts are of great importance, there is a predominant weakness when it comes to securing information assets; the individual user within an organization. Employees are often seen as the weakest link due to human error. Many of the security breaches that occur would not have been possible wit

This thesis will study the notions of governance and corruption and thereby apply it to the case of Jamaica in order to understand how political corruption weakens the country´s governmental legitimacy and principles of democracy. Seeing that corruption is a symbol for the disintegration of state power, it is argued that corruption distorts development of political, social and economic institution

Alberta’s energy sector provides a reliable supply of energy and contributes to the economy of Alberta. In addition to these positive aspects, there are concerns about the environmental, economic and social performance of the energy sector. The purpose of this thesis is to critically examine the production side of Alberta’s energy sector and offer constructive ideas about how the sector could be b
