Linear multi-step methods have been around for more than a century now. But they were with a fixed step-size, where a lot of hand calculations had to be made to find the coefficients of each method separately. It is only recently that variable step-size methodology was introduced and built into the solver. In this thesis, we are exploring this new methodology and at the same time, implementing one

Vi har testat en av teorierna för kvanttermodynamik med Hubbard-Holstein modellen på en dimer. Resultaten visar att effekten av fjädern är att utjämna de typiska kännetecknen i arbetet utfört av systemet. Vi har sett att systemet kan agera som ett batteri som kan laddas. Vi såg också att det var viktigt vilken ordning vi ändrade parametrarna i systemet, som vi förväntade oss av klassisk termodynamThe goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. To this end, the simplest possible lattice model which includes electron and electron-phonon interactions is used, namely the Hubbard-Holstein dimer. The system is time evolved using exact diago

The global COVID-19 pandemic is having tremendous adverse effects on human well-being and the tourism industry, revealing its high vulnerability, and putting the current system into question. A promising more sustainable tourism concept constitutes ecotourism albeit its impacts on residents’ well-being remain unexplored. Addressing this research gap, a qualitative in-field case study was conducted

The “nya gymnasielagen” brought with it a risk that teacher’s marks and attendance rate reports can be a basis for whether or not newly arrived immigrant students can have a continued residence permit. Many teachers who have criticized the law have had worries for the power given to them concerning individual student’s possibilities to obtain residence permits. A striking feature in the debate is

Disaster response is most effective, if a high level of preparedness is in place before natural hazards strike. As many low-income countries are under-financed when it comes to Disaster Risk Reduction, it is lower-cost interventions such as Community-Based Preparedness Trainings that they often rely on to provide strategies to reduce the vulnerability of communities. These trainings are widely use

Abstract Author: Anna Aprea Malmqvist & Vera Nyman. Title: “I’m not a women abuser”- A qualitative study based on men’s violence against women Supervisor: Anna Angelin Assessor: Anders Lundberg Men's violence against women is a constant and relevant topic for social-workers. The perspective of the men and their view of violence is necessary to an in-depth understanding of the complexity o

Bakgrund: Handen är människans viktigaste redskap. Efter en nervavskärning i handledsnivå skadas både rörelse- och känselförmåga i handen vilket påverkar individens aktiviteter i vardagen. Arbetsterapeuter genomför tidig känselträning som är viktigt för att återfå känselförmåga i handen. Syfte: Syftet med studien var att jämföra och utvärdera olika bilder för användning i tidig känselträning. MetoBackground: The hand is humans’ most important tool. After a nerve injury at wrist level, both movement and sensory abilities of the hand are damaged, affecting the individual´s everyday activities. Occupational therapists conduct early sensory relearning which is important to regain sensory abilities. Aim: The aim was to compare and evaluate different images for use in early sensory relearning. M

This thesis is a critical reflection on the metanarratives that are often employed to describe ‘Nordic exceptionality’. In particular, this thesis will look into the anniversary project of ‘Finland100’ as an example of these narratives and approach it as a political project that promises belonging. Narratives surrounding the anniversary will be discussed through a deconstructive narrative reading,

The purpose of this thesis is to gain a greater understanding of how “nätvandrare” and “chat supporters” experience the problem of cyberbullying based on a norm perspective. We are using these two groups as temperature sensors. We are studying young people from “Nätvandrare” and “chatsupporters” point of view. Cyberbullying is a subject that is constantly growing in line with digitalization. In th

The topic of this thesis is the sports law attached to the image rights and intellectual property rights (IPR). The focus is more on the individual athletes when it comes to the commercial use of their image. In this work I study how the individual athletes’ right to their image might possibly be limited. My question layout includes the reflection on how the athletes’ opportunities to use or to co

En hållbar utveckling börjar i skolan Att vi idag står inför stora utmaningar i världen har knappast gått någon förbi. Problem som klimatförändringar, krig och fattigdom är vanligt förekommande ämnen i nyhetsflödet, och dagens utveckling är långt ifrån hållbar. Men vad kan man då göra för att vända den negativa trenden? Ett sätt är att börja i skolan. I princip all gymnasieundervisning ska genoThere are many measures that need to be taken in order to ensure a development that is sustainable. One of them is to educate for a sustainable development and increase the scientific literacy among students. This can create the requisites that are needed in order for students to become active citizens, who make informed decisions that promote a sustainable development in their everyday life. Acco

Denna studie syftar till att undersöka hur unga kvinnor, eller tjejer som jag valt att kalla dem, som studerar på gymnasiets estetiska program upplever sin vardag inom musiken. Musikbranschen är en ojämställd värld och syftet med denna studie är att identifiera skillnader och orättvisor för att musiklärare ska få större möjligheter att arbeta jämställt. Detta jämställdhetsarbete kan bidra till attThe aim of this study is to investigate how young females, or girls as I have choosen to call them, who study at the aesthetic program of high school, experience their everyday lives. The music industry is not equal and the purpose of this study is to identify the differences and injustice, in order to give the music teachers possibilities to work with equality. The work with equality can contribu

Clusters are concentrations of businesses with highly specialized skills and knowledge with an approach to economic development. This approach encourages behavior that is procompetitive within institutions, rivals, related businesses and sophisticated customers so they can work together within a particular nation or region as a tightly connected network. The aim of this thesis is to create a deepe

The dating culture and how one can initiate romantic and sexual relationships have developed and changed over the years. The purpose of this research is to explore the Swedish university students’ dating culture. How Tinder is used and how self-presentation looks on Tinder versus offline among the students. The study uses 10 qualitative personal semi-structured interviews with Swedish students, be

This bachelor thesis is based on a fear of a growing consumption behavior where short lived life cycles of products are causing negative affects on our attempts of building long and healthy relationships to products. The work is also based on a hope of designing products that people are able to appreciate over long period of time. What is it that makes people value and appreciate desig

Purpose: The purpose of this thesis is to investigate how financial risk-taking within companies is related to the CEOs’ and CFOs’ personal characteristics. Theoretical framework: Using the Upper Echelons Theory (UET) (Hambrick & Mason, 1984) and a literature review of previous studies of the UET, hypotheses are built with the aim to investigate the relationship between the UET characteristic

Background In the surroundings of the Dadaab Refugee Camps in Kenya lives a large pastoral population under less favourable conditions than the people inside the refugee camps. Many international NGO’s have started to support the hosting community, but there seems to be a lack of long term oriented development work. This project is based on a wonder over why it apparently is difficult for an inter

Läkemedelsanvändningen ökar för varje år (Apoteket AB 2005) och år 2011 hämtade två tredjedelar av Sveriges befolkning ut ett eller flera receptbelagda läkemedel (Socialstyrelsen 2012). Vid användning av läkemedel tar kroppen vanligtvis inte upp all aktiv substans och rester utsöndras i framförallt urin och hamnar i avloppsvattnet (Wahlberg et al. 2010). Dagens avloppsreningsverk har ingen specielAn inevitable consequence of human drug use is that drug remains end up in sewage water. The sewage treatment plants today are not designed to reduce that kind of chemicals which means that many drugs just pass through unchanged or just modified. These remains affect for example animal life such as behavioral changes or feminization of fish in the recipient. The fact that drug residues already hav
