An Introduction to Hitchin Systems

This thesis aims to introduce the tools that are needed to understand — and historically led to the inception of — Hitchin systems. We lay out a basic theory of Hamiltonian systems on symplectic manifolds, and prove the Liouville-Arnold theorem, which states that integrable Hamiltonian systems admit coordinates in which their solution is basically linear. We then introduce a theory of holomorphic

Andra paragrafen Skatteflyktslagen – Kan lagstiftaren täppa igen hålen i skattelagstiftningen?

För att generalklausulen i den svenska lagstiftningen mot skatteflykt ska kunna tillämpas krävs det att skatteförmånen som uppstår strider mot lagstiftningens syfte. Vad detta innebär är inte fullständigt klarlagt av vare sig lagstiftaren eller av Högsta förvaltningsdomstolen. Lagens syftar till att domstolen ska göra en analog tolkning och dess rättssäkerhet har därför varit omdiskuterad. Syftet For the general clause in the Swedish legislation against tax evasion to be applicable, it is required that the tax advantage that arises is contrary to the purpose of the legislation. What this means is not fully clarified by the legislature or the Supreme Administrative Court. The law aims for the court to make an analogous interpretation and its legal certainty has therefore been debated. The p

Predicting the Movement of the S&P 500 Index using Machine Learning

It is regarded as a highly challenging but important task given the vital role the financial markets play in shaping the global economies. In this thesis, the goal is to predict the movement of the S&P 500 Index using machine learning methods. To this end, we apply two machine learning algorithms, rand

A half-sandwich molybdenum complex with a chloroquinoline derivative

Malaria är en sjukdom som orsakas av encelliga parasiter. De parasiterna bärs av hon-myggor av arten Anopheles som främst befinner sig i de södra delarna av världen. Symtomen som upplevs av malariainfekterade människor liknar förkylningssymptom men även feber, illamående, frossa m.m. Infektionen sprids genom myggbett, sporozoiter sprids i blodet och hamnar i levern där de förökar sig vilket leder A molybdenum complex containing a chloroquinoline derivative has been synthesized; however, due to time restraints, neither X-ray diffraction nor testing of the drug has been accomplished. The identification of the complex relies solely on NMR results, which have also shown partial impurities. Therefore, for future improvements, it is suggested that flash chromatography is run after every step to

Vägavsmalningars konsekvens på vägens livslängd och samhällskostnader

In the last 10 years, sustainability has been in focus and cities are being designed to prioritize sustainable alternatives. Today, narrowing the carriageway is used as an alternative to make way for sustainable alternatives in the existing street space. The purpose of this study is to investigate the consequences narrowing the lane can have on the lifespan of the road structure and what damage it

Potentials and limitations of pantomime storytelling: An experimental study with intersemiotic translation.

When in need to tell stories we often find ourselves using not only our words but also accompanying gestures, as well as pictures. However, what if we were to use only gestures to narrate? Would the stories we tell be clear enough to understand? The thesis investigates the potentials and limitations of pantomime, which consists mostly of gesture, for storytelling. Concretely, through a unique two-

Real time non-invasive estimation of oxygen uptake using smartphones

Syreupptagningsförmåga är en bra indikator av kardiopulmonär hälsa, men be- höver speciell utrustning och är tidskrävande att mäta. Det finns sätt att upp- skatta syreupptagningsförmåga baserat på andra faktorer så som puls och accele- ration. Målet med denna masteruppsats var att undersöka om modeller som upp- skattar syreupptag baserat på accelerationsdata insamlad från sensorer i smartp- hones,Oxygen uptake is a great indicator of cardiopulmonary health but requires spe- cialized equipment and is time consuming to measure. There are ways to estimate oxygen uptake based on other factors such as heart rate and acceleration. The aim of this master thesis was to investigate whether models estimating oxygen uptake based on acceleration data collected from the sensors in smartphones, and step

Affect Poststructuralism and Repressed Emotion: The True Tragedy of The Remains of The Day

Kazuo Ishiguro's novel The Remains of the Day has garnered much discussion by literary theorists. Studies have primarily concerned themselves with the main character Mr Stevens and how he interacts with the complex situations around him. A frequent question is of his reliability, as there are indications that he does not give correct interpretations of events. This essay uses poststructuralist

Sensitive Detection of Blood Biomarker Pentraxin 3 – Development and Comparison of Amperometric and Capacitive Biosensors in Flow-Injection Systems

Mänskligheten strävar ständigt efter att utvecklas och bota olika typer av sjukdomar har varit ett prioriterat område i många hundra år. Idag har vi kommit långt, med många typer av olika antibiotika, målsökande terapier och vaccin. Men för att effektivt kunna behandla sjukdomar krävs att rätt diagnos ställs tidigt. I detta examensarbete har jag utvecklat känsliga analysmetoder som kan ligga till Within clinical diagnostics there is always a need for innovative methods that are rapid, sensitive, and more accurate. In this study two bioanalytical systems have been evaluated for pentraxin 3 (PTX3) detection. PTX3 is a blood biomarker involved in the native immune system that can indicate sepsis, a disease that currently lacks a fast and sensitive analytical method for early detection. Curren

A Study of Quinoline-based organometallic complexes of Ruthenium, Rhodium, and Iridium as potential antimalarial drugs.

Malaria är en sjukdom som orsakas av parasiten Plasmodium och sprids till människor via myggor. Parasiten sprids över nästan hela jorden, men den afrikanska kontinenten är mest drabbad, med 95% av alla fall av malaria i världen. Drabbade får influensaliknande symptom som kommer i cykler, och om sjukdomen inte botas i tid kan den förvärras och bli dödligt. Under en lång tid har det främsta botemedlAntimalarial resistance has diminished the control over the spread of malaria worldwide. Initiated by the discovery of ferroquine, organometallic derivatives of chloroquine have been investigated against resistant strains of Plasmodium, but further work needs to be done. The aim of this project is to expand the available candidates of organometallic antimalarial drugs. In this project, six new org

Vertical greenery systems värdepåverkan på fastigheter

Med en globalt pågående urbanisering har stadsplaneringstrategin förtätning antagits världen över för att skapa urbana miljöer som kan rymma större mängder människor på ett hållbart sätt. Ohållbara konsekvenser har dock uppmärksammats till följd av denna process där grönska och natur är en av stadens dimensioner som har drabbats. Utöver en större värnad av befintliga grönområden inom stadsplanerinWith a globally ongoing urbanization, densification worldwide has been assumed as an urban planning strategy to sustainably accommodate large numbers of people. However, several unsustainable developments have come to attention as a result, where urban green spaces are one aspect that have become negatively affected. Apart from protecting existing natural environments, efforts are made to seek out

Hållbarhetscertifieringars potential att gynna biologisk mångfald

Just nu befinner vi oss i en tid som har nämnts som den sjätte massutdöden. Biologisk mångfald minskar med en oroväckande hastighet och detta har stora effekter på de ekosystemtjänster som vi är beroende av och ständigt nyttjar. För att som konsument kunna bidra till att denna minskning stannar av har flertalet hållbarhetscertifieringar introducerats på marknaden, vilka har som syfte att visa vilkThe purpose of this study is to investigate how and to what extent four different sustainability certifications set standards for conserving or promoting biodiversity. This is of importance since there are a large number of certifications of different kinds on the market and as a consumer it can be difficult to navigate among these. How these certifications favor biodiversity is important to inves
