This paper studies volatility prediction on OMX Stockholm 30, OMX Helsinki 25 and OMX Nordic 40. The models used are a historical variance model, an exponentially weighted moving average model and three models from the GARCH family. These are GARCH(1,1), EGARCH(1,1) and GJR(1,1), with normal and t-distribution respectively. The volatility for 2008-2013 is forecasted with a rolling window technique
Ett avgörande om vårdnad, boende och/eller umgänge som inte följts kan verkställas enligt 21 kap. föräldrabalk (FB), förutsatt att det inte är oförenligt med barnets bästa. I sådant fall kan beslutet förenas med tvångsmedel i form av vitesföreläggande eller polishämtning. En ansökan om verkställighet ska avslås om det finns en risk att barnet far illa eller om barnet motsätter sig verkställighet o
Limited-slip differentials (LSD) are normally placed in high-end and race cars to improve the handling, by reducing the differential speed and balancing the torque between the driving wheels. However, electrical-activated LSD struggles to continuously eliminate the differential speed over extended periods of time. To overcome this, BorgWarner proposed a dual-functional clutch pack, featuring two d
Amelogenin, a critical protein in enamel formation, self-assembles into supramolecular structure that guide hydroxyapatite (HAP) crystal growth that is essential for the development of strong and healthy enamel. Phosphorylation of amelogenin at Ser-16 plays a pivotal role in modulating its self-assembly and functional properties, impacting the overall enamel biomineralization process. This post-tr
Bioacoustic sound event detection (SED) is a critical field for biodiversity monitoring, yet the high cost of annotating data poses significant challenges. This thesis explores the application of active learning strategies to reduce the amount of annotated data required for effective model training. This is done for a segment based SED model, where batch active learning is performed by querying fu
There is an increased demand for managing the complex hospital organisations in which healthcare personnel operate within, which is even more so evident from today's healthcare crisis in Sweden. Since the World Health Organisation (WHO) emphasised the importance of interprofessional collaboration in 2010, research on this area has increased. However, much of the research considers only one act
Food Waste is a global issue concerning the environment, resources, social justice and economy. Despite being so pressing, around one-third of food produced is discarded worldwide. Meanwhile, food waste is incredibly complicated, requiring collaborations of all stakeholders and various innovations. Too Good To Go (TGTG) utilizes technology to bridge consumers and food business and save food waste
This chapter addresses opportunities and challenges in urban planning by implementing the concept of ecosystem services in an urban tourism and destination development context. In analysing ecosystem services in urban tourism, we contribute to an emerging literature focusing on urban ecosystem services. An important research gap is also addressed; despite the importance of tourism for cities, ther
The authors have collected data for the silver market, shedding light on market size, stocks in society and silver flows in society. The world supply from mining, depletion of the remaining reserves, reducing ore grades, market price and turnover of silver was simulated using the SILVER model developed for this study. The model combines mining, trade markets, price mechanisms, populations dynamics
I betänkandet Se barnet och propositionen Ett stärkt barnrättsperspektiv i vårdnadstvister behandlade utredaren respektive regeringen bland annat ett förslag om att införa en bestämmelse om automatisk vårdnadsöverflyttning vid dödligt våld inom familjen. Enligt utredaren och regeringen är det bäst för barnet att den förälder som har dödat barnets andra förälder inte är vårdnadshavare eller har någ
This thesis describes the development of an autonomous weeding vehicle for the agricultural industry. It has been done as a project at RMIT University in Melbourne and the aim was to develop a design for the vehicle which could later be used to develop a commercial product. The current trend in the agricultural industry is larger machines that can benefit from economies of scale. These heavy mac
Peer-to-Peer (P2P) energy trading in microgrids is an innovative solution to local energy problems where consumers produce and sell their energy to their neighbours. The idea of a microgrid-based local energy trading enables decentralised energy system and strengthens consumers' participation. In the context of developing countries, microgrids play an important role in securing the mere access
Faderskapspresumtionen i 1 kap. 1 § föräldrabalken innebär att maken till en gift kvinna som föder ett barn automatiskt blir barnets fader. Samhället och sätten vi samlever och bildar familj på förändras ständigt, varför det finns anledning att undersöka om faderskapspresumtionen har spelat ut sin roll. I uppsatsen undersöks just detta och faderskapspresumtionen sätts i relation till sin samtid ocThe presumption of parenthood under Chapter 1, Section 1 of the Children and Parents Code provides that fatherhood is presumed for a man who is married to a child’s mother. Society, cohabitation forms and the ways in which families are created are constantly changing, which raises the question of the pertinency of the presumption of parenthood. This is analyzed in the thesis and the provision is p
I denna uppsats undersöks de möjligheter en våldsutsatt kvinna har att fysiskt åtskiljas ifrån en våldsutövande manlig partner i Sverige respektive Finland. Fokus i uppsatsen ligger vid sammanboende par. Genom studien har jag sökt efter att identifiera brister och styrkor i ländernas lagstiftning, för att sedan analysera huruvida och i vilken utsträckning lagstiftningen uppfyller ett våldsförebyggIn this thesis I examine what legal options a female victim of domestic violence has at her disposal in order to be physically separated from the perpetrator in Sweden and Finland, respectively. The subject of examination is a man and a woman in a relationship that are either married or romantic cohabitants. Through this study I have strived to identify the strengths and weaknesses in both the Swe
Oil has been the major fossil fuel since the days of its discovering. It takes a special place in the international energy trade regime, as it is an exhaustible natural resource sensitive to political and economic changes. The instability in oil prices may lead to a considerable disruption of the global economy. The ongoing liberalization of oil markets, the forthcoming WTO accessions of major ene
Hotel fires in Sweden are a precarious issue since hotel guests are sleeping in unfamiliar surroundings and that the new legislation in 2004 clarified the owners’ responsibility for the safety of their guests. In 2004, two people were killed in a hotel fire and the owner was subsequently sentenced for unwillingly manslaughter. With an entirely qualitative approach, this analysis investigates how l
The purpose with this master's thesis has been to develop a new generation of fencing gear, creating new opportunities in usage and functions to meet future needs within fencing as a sport. The projects main focus areas: * Increasing the popularity of fencing * The development of fencing equipment * The future demands on fencing as a sport The project resulted in a further development of exist
Glycoproteins represent a group of important biomarkers for cancer and other life-threatening diseases. Selective detection of specific glycoproteins is an important step for early diagnosis. Traditional glycoprotein assays are mostly based on lectins, antibodies, and enzymes, biochemical reagents that are costly and require special cold chain storage and distribution. To address the shortcomings
Accurate knowledge about the amount and dynamics of terrestrial gross primary productivity is an important component for understanding of ecosystem functioning and processes. Recently a new diagnostic model, Southampton Carbon Flux (SCARF), was developed to predict terrestrial gross primary productivity at regional to global scale based on a chlorophyll index derived from MERIS data. The model aim
