It is crucial for the insurance business to create risk profiles for their customers to be able set a fair price for their insurances. This thesis presents an alternative method for measuring the dependence between the numbers of claims made by a customer holding two insurances. The group of insurance holders consisted of 74770 unique customers holding at least two insurances during one year. The
Solar energy simulations are used to quantify the potential of the passive use (daylight, solar gains) and the active use (photovoltaics and solar thermal) of solar energy. The simulations can be performed at different scales e.g. buildings, neighbourhoods and cities, with different requirements on the data. For example, for the neighbourhood simulations we need simplified building geometries that
We present a decomposition approach to a class of social welfare optimization problems for optimal power flow in multi-region electricity networks. The electricity network is decomposed into multiple regions which decide independently over the amount of power produced within the region and exchanged with neighboring regions. We decompose the overall power flow (or social welfare) optimization into
In this study we compare different volatility models on their ability to forecast one day ahead volatility and value-at-risk (VaR). We compare five different GARCH specifications: GARCH, IGARCH, GJR-GARCH, EGARCH and APARCH, as well as EWMA, each paired with six different conditional distributions. These models are used to forecast volatility and VaR one day ahead using daily return data from the
It can be difficult to engage colleagues with the findings and recommendations of an externally-funded project, even when, or perhaps particularly when, it has major implications for institutional processes. The authors were involved with a large single-institution Higher Education change project that aimed to make the university more responsive to changes in curriculum needs, the student voice, e

‘Save file empty’: ALM institutions’ and game developers’ thoughts regarding digital games preservation This master’s thesis examines attitudes towards the preservation of digital games in Malmö, Sweden. Malmö is one of Europe’s largest gaming hubs and is home to many game studios. Digital games are one of Sweden’s largest cultural exports but very little has been done in order to preserve this h
We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. Then we investigate the tails of innovations of ARMA-GARCH models using the Peaks over thresholds method and find that the distributions of stock returns are asymmetric
Summary: Floodwater mosquitoes occur in temporary flooded areas and can cause tremendous nuisance in the near and far surroundings. In the Nedre Dalälven region in Central Sweden, mosquito control is based on application of the biological larvicide Bacillus thuringiensis israelensis (BTI) by helicopter. Precise mapping of the floodwater mosquito breeding sites, a prerequisite for successful BTI tr
We study a network formation game where n players, identified with the nodes of a directed graph to be formed, choose where to wire their outgoing links in order to maximize their PageRank centrality. Specifically, the action of every player i consists in the wiring of a predetermined number di of directed out-links, and her utility is her own PageRank centrality in the network resulting from the
Att kunna följa och spela in handbollsmatcher automatiskt skulle kunna vara ett kraftfullt verktyg för både spelare och tränare vid utvärdering av lagprestationer. Automatisk inspelning skulle aven kunna användas för att webbsända matcher. Även om elitmatcher i handboll ofta spelas in, är syftet med inspelningarna inte att ge tränare data om hur laget har spelat. När idrott spelas in för att sändaThis thesis presents and evaluates different models aimed at tracking the play in handball matches. The tracking is designed to be used with automatic broadcasting of handball matches without any camera operator present. To solve this problem the Kanade-Lucas-Tomasi tracker is used to generate data of player movements on the handball court. From the tracker data, features are extracted and used as
En människa exponeras och angrips varje dag av virus och bakterier och immunförsvaret skyddar oss från dessa angrepp. Immunförsvaret utgörs av vita blodkroppar som bildas i benmärgen och sprids vidare ut i kroppen. De vita blodkropparna finns i många olika varianter och varje variant har en specifik uppgift. Lymfocyter är en typ av vita blodkroppar och kan dela in i två huvudgrupper: Blymfocyter oToday antibodies are an important part in the treatment of diseases such as cancer and Guillain–Barré syndrome. It is of course important to be able to regulate the levels of the antibodies in the treatment. In this study a general method for antibody production were investigated. The antibody construct was made for transportation out of the cell. Four different tagged variants of an antibody wer

Jag har identifierat ett speciellt samarbetsproblem inom området frånskilda föräldrars umgänge med sina gemensamma barn. Det handlar om att ena föräldern inte fullgör sitt umgänge utan bara uteblir. Jag har kallat detta för omvänt umgängessabotage. Jag har inte i dagens regelverk funnit någon rättslig lösning när detta problem inträffar. Därför har jag undersökt om problemet kan förebyggas i förväI have identified a problem of cooperation in the field of divorced parents spending time with their children. The problem is that one parent is deliberately absent and not fulfilling the agreements of spending time with the children. I have called it reverse visitation interference, and I haven’t found any legal solution to it. Therefore, I have evaluated if the problem can be prevented by agreement
Non-fungible tokens (NFTs) are a type of cryptocurrency that consist of unique, non-exchangeable tokens, which are traded on a blockchain. These unique tokens are associated with digital assets such as images, art, videos, or music. With the rapid rise of NFTs’ popularity in 2021, a community established around trading, selling, and collecting of NFTs. This study explored the NFT community at larg
This paper reports on an empirical comparison of two prominent measures of individual risk attitudes - the Holt and Laury (2002) lottery-choice task and the multi-item questionnaire advocated by Dohmen et al. (2011) - with respect to their within-subject stability over time (one year) and their correlation with actual risk-taking behavior in the lab - here the amount sent in a trust game (Berg et
