År 2012 hittade man Higgs boson vid LHC i CERN, den här partikeln är nyckeln för att beskriva hur partiklar får sina massor i standardmodellen. Vad vi fortfarande inte vet, är vilka massor partiklarna får. Detta måste mätas experimentellt och är inte något vi kan teoretiskt förutsäga. Det visar sig att de observerade massorna är vitt skilda, vi har allt från toppkvarkens massa: 172 GeV $\approx 3\In this Master thesis we extend the Standard Model with an additional $U(1)$ gauge group and an additional Higgs doublet with a lepton specific $\mathbb{Z}_2$ symmetry. This is used in a gauged version of the Froggatt-Nielsen mechanism to describe the observed masses and mixings among fermions. To reproduce these observables and satisfy the anomaly constraints posed by the new gauge symmetry metho

17 kap. 10 § LOU stadgar att ett kontrakt eller ramavtal får ändras i enlighet med en ändrings- eller optionsklausul utan att en ny upphandling måste genomföras, om kontraktets eller ramavtalets övergripande karaktär inte ändras, om klausulen har angetts i något av upphandlingsdokumenten och klart, exakt och entydigt beskriver under vilka förutsättningar den kan tillämpas. Vidare ska klausulen äve17th chapter 10th § of the Swedish Public Procurement Act statues that a contract or a framework agreement may be modified without a new procurement procedure in accordance with a review clause or option, if the clause does not provide for modifications that would alter the overall nature of the contract. The review clause shall be set out in the initial procurement documents. Such a clause shall

Grönlands inlandsis utgör världens näst största färskvattensreservoar. Forskning har visat att Grönlands inlandsis förlorar mer och mer massa, vilket också bidrar till den stigande havsnivån, i kombination med andra faktorer. Avrinningen förväntas också öka i framtiden på grund av den globala uppvärmningen. Hur mycket massa som lämnar Grönlands inlandsis beror på den totala massbalansen. Den totalThe Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. Surface mass balance (SMB) plus the dynamic mass losses fr

The aim of this thesis was to develop the Uniti One window design from a prototype stage to be ready for mass production. Uniti One is a lightweight, two-seated, electric vehicle of the L7e-category designed for urban transportation. In late 2017, three prototypes of this vehicle were built, and that construction was used as the start point of the development. Vehicle regulations, material theory

This thesis consists of a critical discourse analysis regarding the integration of asylum seekers and individuals with a residence permit in Sweden. Its analysis is divided into two parts; the first part focuses on how four Swedish authorities work together to integrate these individuals in Sweden. The second part of the analysis emphases the participation of the Swedish Red Cross in the integrati

Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. This thesis will provide proof of how commutation failures causes abnormal behavior in the AC network, and how PMU data can be used in order to distinguish

Diabetes is an increasing problem in the world, where obesity is a large risk factor for developing the most common type of diabetes, i.e. type 2 diabetes. Numerous pharmaceuticals exist for managing the disease. The importance of the consumption of healthy foods is less emphasised albeit being an important and effective tool for managing the disease. The master thesis aimed at investigating how c

The aftermath of the European Union’s ‘migration crisis’ in 2014-2016 continues to challenge the European security discourse, marked by a dilemma of securing the internal Member States political, societal and economic sector, whilst providing human security for forced migrants in accordance with international obligations. This thesis therefore aims to elucidate the dynamic between state security a

Our intention of this research was to study how treatment assistants who is working in two different treatment houses for addicts are considering the way out of alcohol and narcotic substances addiction. The two different treatment houses are one motivation clinic and one support clinic. We have chosen a qualitative method with semistructured interviews in this research where six treatment assista

The intrastate conflict between the Maoist inspired rebel group the Naxalites and the Indian government have been active since the late 1960s. This qualitative case study, use parts of Jacob Bercovitch’s framework ‘Contingency Model of Mediation’ to interpret the obstacles found in this case, in order to reach a successful negotiation situation. Six different factors in the conflict were analysed.

The study aims to increase our understanding of the limitations and benefits of structural and agent-oriented accounts in explaining the success and failure of peace negotiations. The propositions of ripeness and readiness theory are analysed through the lens of the agency-structure debate. Implicit assumptions on the nature of agents and structures, contained within the theories’ propositions on

1975 marked the end of the Spanish dictatorship under the rule of General Francisco Franco and the transition to democracy. Yet, the Basque ethnopolitical militant group Euskadi ta Askatasuna (ETA) continued its violent struggle until 2017, several years after the end of the dictatorship, while the otherwise peaceful independence movement in Catalonia began escalating following an illegal referend

During the manufacturing of a paperboard-based package, the material is in one step folded to obtain the desired shape of the end product. Prior to this step, the material undergoes another processing step, creasing, in which the material is damaged along the folding lines. The result of the creasing process is that the material delaminates which, in turn, causes the material to fold in smooth lin

With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations, dynamic charge through Electric Road Systems (ERS) is in development, and fast charging stations are being deployed all over the world. This thesis focuses on combining the use of both technologies, attempting to use an E

Can artificial training data be used for deep learning applications in computer vision? We investigated this by building a framework that uses computer graphics to generate large quantities of images portraying humans. Generative Adversarial Networks (GANs) were used to bridge the gap in appearance between the generated and real images. A dataset’s potential was estimated by first using it to trai

There is no miracle material or wonder method of the future that will allow us to keep the lifestyle of mass consumption we have grown accustomed to. If we keep neglecting the climatic changes happening around us we will face quite a turbulent fu- ture. Due to societal unrest and resource scarcity we will need to rethink how we use and design objects, we need to think ho- listically with products

Enligt Socialstyrelsen (2017) är förekomsten av ångest bland barn cirka 10 %. Studier visar att sen eller utebliven behandling kan leda till långsiktiga biverkningar i olika aspekter. Med tanke på detta är det viktigt att erbjuda vård för att förhindra negativa följder som psykiatriska sjukdomar. Studier har visat att KBT är en effektiv behandling för ångestsjukdomar som uppträder under barndomen,

Current concerns for how unsustainable plastic packaging waste management is and how it negatively affects the environment, combined with the fact that it does not promote a circular economy has given origin to a strategy for plastics in a circular economy defined by the European Commission, in 2018. Thus, this study intended to compare and analyse two different plastic packaging waste recycling s
