This thesis will investigate the possibility to have SU(2) gauge fields as the source to the Cosmic Inflation and/or to the Dark Energy. It will be explained that, under certain conditions, the Universe can be filled with vector fields without violating its isotropy. Those conditions are naturally fulfilled within the SU(2) gauge theory. Both Einstein's equations and the equations of motion

De senaste åren har Sverige sett en kraftig ökning från utbyggnaden av vindkraft. År 2015 fick Sverige ca 16 TWh el från vindkraftsproduktion, och regeringens mål om 30 TWh el från vindkraft per år från och med år 2020 ser mycket väl ut att kunna uppnås. Tack vare skattelättnader och subventioner till vindkraft, samt elcertifikatsystemets inverkan så har mängder av investeringar gjorts. Vindkrafte

Går det att stoppa den globala uppvärmningen genom lokala klimatexperiment? För att begränsa den globala uppvärmningen måste industriländerna till 2050 minska utsläppen med 80-95 %. En sådan omställning är en enorm utmaning, men forskning visar att den är möjlig att genomföra genom nytänkande samhällsstyrning som involverar samhällets samtliga aktörer. Ett nytt spännande sätt att tackla det globaThe response to climate change in cities has proliferated over the last few decades, and progressive climate action at the local level is now ubiquitous. More specifically, local climate action often comes in the shape of ‘climate change experiments’, radical innovations at the local level designed to respond to the imperatives of mitigating and adapting to climate change in the city. This thesis

In recent years new ways to deal with trade barriers, aside from the traditional tariff and quota reductions, has been introduced to trade negotiations. These have the collective name of trade facilitation and focuses on the less visible parts of barriers to trade. As this started to be discussed in policy circles economic research picked up interest as well. However, focus in the research has bee

The rise of Big Data is creating tremendous opportunities across all industries. As the development promises disruptive changes of business processes and manifold benefits both on the company and customer side, health and life insurance companies engage and invest in Big Data approaches. By collecting, storing, and analysing huge amounts of customer centric data, they hope to enhance their risk as

The fact that educational buildings are places where the majority of us spend most of our formative years, their design plays an important part in improving the education level and well-being of society. A number of changes have been made to the traditional design of these buildings in the last few decades and the old education system, where the teacher solely acts as an informer and the children

Sony Mobile Communications (SoMC) perpetually collect large amounts of prototype device data into their database which is used for analysing their devices. Different areas are analysed individually using this data but no general model exists which encapsulates the overall performance. A desired model would include information from the different key performance areas and utilise machine learning wi

Expatriate är en gränsöverskridande identitet i dagens globala samhälle som förknippas med en tillfällig arbetsposition utomlands. Den kritik som riktats mot begreppet, att det är ett begrepp reserverat för Vita västerlänningar, går i linje med en postkolonial teoretisk strävan att problematisera de begrepp och språkliga gränsdragningar som används i den globala diskursen. Uppsatsens syfte är att

The practice of translation has many different approaches. By comparing and discussing three different Swedish translations of 'The Hobbit', this text discusses what factors affect literary translation and how these influences have changed over time. In this essay, I investigate how the translations 'Hompen, eller En resa dit och tillbaks igen' (1947), 'Bilbo: En hobbits äventy

In 2011, Icelandic compulsory schools introduced a new national curriculum. Its purpose was to enable a more competencies-based school system where focus would be on independence and initiative. One of the main changes in the curriculum was the introduction of entrepreneurship as a core competency. Similar changes have taken place elsewhere in Europe and there are indications that comparable devel

2 Abstract This paper deploys methodology typically utilized in financial econometrics, namely univariate and multivariate GARCH-M forecasting techniques, as inputs into the Black-Litterman asset allocation process. While previous works have examined the usefulness in deploying select GARCH specifications as a source for the required Black-Litterman views vector, to the best of our knowledge, this

Bacteria can live in a surface attached community called biofilm, where microorganisms can multiply, grow and produce extracellular polymeric substances (EPS) and biofilm formation proceeds in different stages from attachment to a mature biofilm. In food industry, biofilms are a significant issue that can affect product quality and safety when biofilms are formed in the processing equipment. The

I alla industrier där partiklar behandlas i torra prover är segregering ett stort problem. Segregering kan ske vid olika steg i processen där partiklarna i fråga till exempel transporteras, blandas eller bara lagras. Det uppskattas att uppemot 30 % av all fördröjning i processer sker på grund av segregering av partiklar(Johanson, 2014). Detta leder till kritiska konsekvenser för ett företag så somSegregation is a well-known process problem that may cost companies quality and time. The aim of this project was to establish a fundamental understanding about sifting segregation by using the sifting segregation tester described in the ASTM International standard. In this work, Cellets and Suglets were used to study particles tendency to segregate at different weight ratios and different particl

Flooding of urban areas is a worldwide problem as cities grow and the amount of impermeable surfaces increase generating more surface runoff. In the Zambian city of Ndola, the capital of the Copperbelt Province, flooding occurs in some parts of the city especially on Dag Hammarskjöld Drive at the underbridge, which has been flooding every rainy season consecutively for 8 years now. The main object

Syftet med examensarbetet är att ta fram en mer tillförlitlig leveransprestationsmätning av Orkla Foods Sveriges leverantörer vars resultat kan kommuniceras både internt och externt för att långsiktigt förbättra leveransprestationen. När denna studie genomfördes hade Orkla Foods Sverige problem med låg leveransprestation från sina leverantörer och otillförlitliga mätningar av detta som grundade s

Estonia has taken an upward trend in terms of innovation and economic growth since 1991 and is currently the most prosperous ex-USSR country. Moldova on the other hand, another ex-USSR country, is one of the poorest countries in Europe and it has more or less stagnated for the past 2 decades in terms of innovation and R&D. Estonia’s NIS (National Innovation System) has evolved remarkably and w

Användandet av agila utvecklingsmetoder inom IT-organisationer har utvecklats till att inkludera driftsidan (Ops). DevOps är en rörelse för ökat samarbete mellan utvecklare (Dev) och driftpersonal (Ops) med rötter i agila utvecklingsmetoder där de fyra värdegrunderna är kultur, automation, mätning och delning. Rörelsen lockar företag i hopp om snabbare time-to-market och en bättre möjlighet till

Education for sustainability (EfS) has been regarded a promising approach for solving sustainability challenges. Results have been unsatisfying due to a knowledge-dissemination focus in the formal sector. Reasons are economic and political interests shaping formal education. Therefore, hopes are placed in the non-formal sector to close this knowledge-to-action gap. In this case study, I aim to und

The aim of this study was to describe and analyze how parents relate to their children’s internet use. Studies have shown that children nine years and older have increased access to private tablets and smartphones, leading to unsupervised online opportunities. With increased use, parents must take responsibility to protect their children from risks associated with the internet. We have examined; 1

This report describes a part of the product development process for a mechanical adjustment of the head pressure in an extruder at Tetra Pak. The pressure is adjusted by a valve that increases or decreases the pressure by moving a valve stem. In the current solution the valve stem is moved by hand, which will no longer be effective when Tetra Pak streamlines the extruder. The project also includes
