Risk and risk aversion are crucial concepts in finance. Models in finance typically assume a known probability distribution of returns, which does often not hold in reality. This papers aims to measure the uncertainty surrounding the probability distribution in equity markets and to evaluate if such uncertainty is priced. Our study defines uncertainty as the volatility of the option implied volati

Purpose: This thesis delves into the dynamic relation between awe and art, specifically focusing on abstract versus representational art within immersive Virtual Reality (VR) environments. Prompted by the expansion of awe research since Keltner and Haidt’s seminal work (2003) and the research gap on art and VR, this study explores whether the level of abstraction in art influences the intensity of
En vanlig orsak till dödsfall globalt sett är cancer, och det har varit ett intensivt forskningsområde under de senaste årtiondena med inriktning på biomedicinsk forskning. Det finns tre vanliga etablerade cancerbehandlingar som är kirurgi, cellgiftsbehandling och strålbehandling. Även om dessa behandlingar förlänger överlevnadstiden för patienterna, så är de ofta otillräckliga vid behandling av cCancer is a leading cause of mortality worldwide, and despite the effectiveness of established treatments such as surgery, chemotherapy, and radiotherapy, they may prove inadequate in advanced stages. These treatments can cause severe side effects, such as immune suppression and damage to healthy cells, which can lead to resistance and hinder treatment effectiveness. Immunotherapy is another estab

Sedan papperförpackningens entré under 50-talet har Tetra Pak varit en självklarhet i många kylar världen över. En stor del av de Tetra Pak-förpackningar som produceras behöver dock inte stå kylt eftersom de är gjorda på en speciell sorts material med en barriär som skyddar den förvarade produkten även i rumstemperatur. Denna typ av förpackningar kallas för aseptiska och de gör transport och förvaAseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. This thesis consists of two parts regarding in-plane wetting into the paperboard.

Användning av digital storytelling och multimodala tekniker skiljer sig markant för B2C och B2B företag. Effekten av digital storytelling för företags trovärdighet och företagsidentitet i B2B-sammanhang och särskilt för företagens “om-oss” sidor är sedan tidigare relativt outfors-kad. Studien underbyggs av fyra intervjuer med personer från fyra olika branscher och olika anställningsnivå. ResultateThe use of digital storytelling and multimodal techniques significantly differs between B2C and B2B companies. The effect of digital storytelling on corporate credibility and corporate identity in B2B contexts, and particularly for companies' "about us" pages, is relatively under-researched. The study is supported by four interviews with individuals from four different industries and

This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. This spectrum is subsequently modeled to pass thr
Detta examensarbete utforskar det relativt outforskade fenomenet venture studios (även känt som bolagsbyggare, venture builders och startup studios), vilka är företag som systematiskt bygger bolag. Trots att antalet venture studios ökar så är akademisk forskning kring ämnet relativt begränsad. Denna studie syftar till att fylla denna kunskapslucka genom att genomföra en fallstudie på sex svenska vThis master's thesis explores the relatively unexplored phenomenon of venture studios (also known as venture builders or startup studios), which are companies that systematically and concurrently build startups. Despite their growing popularity, the academic literature on how venture studios operate is still limited and no structured and extensive description of the business model appears to e
Precis som arkeologer gräver i jordens historia finns det astrofysiker som gräver i Vintergatans förflutna. Det finns ingen fullständig bild över Vintergatans evolution. Därför är galaxformationen ett relevant ämne inom astrofysiken. När man grävt i ljusspektra och rörelsedata av stjärnor i vår galax har man funnit att många stjärnor har sitt ursprung utanför Vintergatan. En galax som rör sig geThe Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. In this project we create candidate lists of stars that are likely to originate from past merger events experienced by the Galaxy, usi
