It is well-known that long memory and regime switching in the first moment of a stochastic process are easily confused. But the relation between long memory in the second moment and regime switching in the second moment is less well understood. We perform a simulation study in which we assess the possibility to distinguish the two properties in the case that data with long memory in the second mom

Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature. S

Åklagarens objektivitetsplikt har under de senaste åren blivit särskilt uppmärksammad med anledning av Thomas Quick-fallet. Under 90-talet erkände Quick ett 30-tal mord, varav han blev dömd för åtta av dem. Emellertid förändrades allt år 2008 när Quick tog tillbaka sina erkännanden. Detta ledde till ett antal omprövningar, där han så småningom blev friad från samtliga åtal. I såväl domstolar som m

Language is a social act and the fact that social communities create new or change existing words that are known in daily standard language, can make the lexicon difficult to comprehend for the ones not involved. The communication that belong to a specific social group can be classified as a jargon, and in this present study we look at gaming language as an example of how social communities’ lexic

3D-models of bone structures from computed tomography (CT) data can be used for surgical planning, education and a wide range of other purposes. They can also be used in both digital and 3D-printed format. The currently used process to obtain such models consists of a combination of thresholding, morphological operations and manual adjustments. This can be very time-consuming. Deep Learning (DL) c

Uppsatsen handlar om sekretessmarkering som omfattar barn då sekretessmarkeringen är tillkommen med anledning av barnets andra förälder/vårdnadshavare. Uppgifter om hot och våld är i studien inte styrkta genom dom. Arbetet rör sig inom fälten familjerätt – offentlig rätt. Syftet med uppsatsen är att undersöka effekter och konsekvenser av en sekretessmarkering. Är gemensam vårdnad och umgänge möjli

Precis som en viss färg kan beskrivas som en specifik blandning av grundfärgerna, så kan också en elektron också beskrivas som en slags blandning. Den här blandningen kan påverkas av ljus så att "mängden" av de olika komponenterna förändras. Det här är intressant att undersöka, för om vi vet vilka förutsättningar som gör att elektronen hamnar i en viss blandning, så kan man återskapa de This project aims to study the process of electron excitation by a light pulse, a process at the core of many important contemporary and possible future devices. Data from an experiment where the electron dynamics is probed with attosecond laser pulses are analyzed in order to gain insight on the rapid population oscillations within the excited atomic system and simulations are constructed with th

The purpose of this project was to study the interaction which takes place between school counselors and undocumented children in the Swedish school system. Qualitative interviews with seven school counselors have been conducted to highlight their experiences of working with children who find themselves inside the society's geographical boundaries, yet with limited civil rights. The theoretica

The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. wheat or corn, for biofuel is controversial as it competes with food production. F

Integrering av ekosystemtjänster i miljökonsekvensbeskrivningar Ekosystemtjänster kallas de varor och tjänster som ekosystemen bidrar med till människans välbefinnande. Produktion av grödor och virke, växters förmåga att lagra koldioxid samt ekosystemens förmåga att rena luft och vatten är alla exempel på ekosystemtjänster. Trots att dessa tjänster är ovärderliga för mänskliga samhällen är det s

Det saknas möjlighet att genomgå en surrogatprocess inom vården i Sverige. Svenska par och ensamstående vänder sig istället utomlands för att anlita en surrogatmoder. Därefter ämnar de bli erkända som rättsliga föräldrar till barnet eller barnen i Sverige. Sverige har intagit en negativ ställning till att införa surrogatmoderskap i Sverige och vill inte heller underlätta för enskilda som vänder siSince there is no possibility for surrogacy arrangements within Swedish health care, couples and singles turn abroad to hire a surrogate mother. Upon completing the process they aim to be recognized as legal parents to the child or the children in Sweden. Sweden has taken a negative approach to introducing surrogacy in Sweden and do not want to facilitate individuals going abroad. In the cases whe

The aim of this study was to examine social workers and staff at women’s shelters experience of how the responsibility for abused women is distributed between them through collaboration. The study relies on eight qualitative, semi structured interviews with professionals, whom play a significant role in supporting abused woman, in two different municipalities in southern Sweden. In order to analyz

There are almost 6 000 acutely homeless in Sweden, according to the most recent estimation. The acutely homeless do not have any type of accommodation and so they have to rely on shelters for a half-decent place to sleep, but shelters are not always available and some people do not want to stay in shelters. When sleeping on the streets you are exposed to the public, but also to rain, wind, s

When looking from the outside, Sweden is an exceptional country, with a tradition of neutrality and no notable colonial past; but history paints a different picture. This thesis investigates the portrayal of Sweden and the impact of narratives of Swedish exceptionalism in the Historiska Museet in Stockholm, through the analysis of the depiction of Swedish colonial history and Human Rights discours

In workplaces, a lot of knowledge is lost when colleagues change positions. What was once obvious to one person can be incomprehensible to the next. This problem has been encountered by Probation Labs Sweden AB with their biochemical instrument, Labbot. Labbot facilitates researchers in automating their protein analysis. It works like a multi-tool where users can perform one or several tasks in a

On January 4th, 2022, new restrictions under the Europe-wide REACH protocol on chemicals hit the tattooing industry when the content of inks came under regulation. This essay seeks to find out how this directly has impacted tattoo artists and their ability to work. To achieve this a phenomenological approach was used, and data was collected through six semi-structured, qualitative interviews with

The thesis discusses the abuse of the freedom of establishment of companies in the Internal Market and the change that the Directive of the European Parliament and of the Council (EU) 2019/2121 of 27 November 2019 amending Directive (EU) 2017/1132 as regards cross-border conversions, mergers and divisions [2019] OJ L 321/1 (Mobility Directive) creates to that. The research question of this thesis

Transgender persons experience a disproportionate representation in adverse mental health conditions globally. In Sweden there are tangible efforts to improving mental healthcare overall, but as a minority population, transgender persons still struggle with meeting their mental healthcare needs. While social factors such as stigma and discrimination act as catalysts for this burden, there is an ab
