This study will examine five GARCH model’s (GARCH, IGARCH, EGARCH, APGARCH and GJR-GARCH) capacity to determine the daily Value at Risk (VaR) of the OMXS30 stock indices, which contains 30 companies with the highest turn-over on the Stockholm Stock Exchange.
In today’s Europe which is facing increased immigration flows and xenophobic attitudes, there is a growing pressure on creating integration policies which have the ability of dismantling negative attitudes. As intercultural dialogue is believed to decrease these attitudes and create an inclusive society, the aim of this thesis has been to critically review the Swedish multicultural integration ap
In the wake of alarming reports from IPCC, policy makers all over the world have recognized offshore wind power to become an essential contributor in the future renewable energy system and battling of climate change. However, many countries including Norway lack extensive areas of shallow water suitable for conventional offshore wind, hence an interest for deep offshore solutions has arisen. One o
Mapping and quantifying forest information about e.g. land cover, tree height and biomass has traditionally been a both time-consuming and labour-intensive part of forestry and forest research as field measurements typically are collected manually using handheld equipment. Remote sensing has proved to be a valuable complement to field based measurements as it enables for fast and relatively cheap
The electron transmission probability in semiconductor heterostructures made of potential barriers whose height, width and separation are modified to follow different Gaussian functions are calculated using the transfer matrix theory. These structures then serve as electron obstacles in thermoelectric devices in order to increase the output power and efficiency. When computing and comparing these
The purpose of this study was to describe the life balance of four men who have completed the first phase of their recovery from stress-related disorders through the model of life balance. Stress-related disorders are today a major public health issue. Psychological stress is the most common reason for sick leave in Sweden. Life balance is measured by how the individual, through one’s occupational
The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a
Foraminiferer förekommer i marina sediment i världens hav och utgör en värdefull proxymetod för att rekonstruera vattendjup, strömmar, produktivitet och syrenivån vid djuphavsmassor. Valet av storleksfraktion som används när studier på bentiska djuphavs-foraminiferer utförs har visat sig ha betydelse när ekologisk fauna vid upvällningsregioner studeras. En genomgång av tidigare studier har visat aForaminifera are abundant in the marine sediment in all of the worlds’s oceans and offer a valuable proxy method to reconstruct water depth, circulation, productivity and deep water aeration. The choice of size fraction used when studying benthic foraminifera in upwelling areas are important. A review of 15 earlier studies where benthic foraminifera has been analysed, has shown that there are diff
Energy Management needs global attention due to increase in energy demands over last two decades. Commercial buildings and Industrial Facilities are the two most intensive energy consuming sectors that results in high energy expenditure cost and carbon emissions. They have shown interest in energy efficiency and energy management programs to save energy and reduce carbon footprints due to governme
Emotions are influential in determining individuals to donate to charitable causes. However, emotions could interfere with the later decision to whom to allocate the donation resources by making people more likely to donate to a few individual victims instead of many statistical ones. Nevertheless, rationality could direct the allocation decision on the right way (i.e., by donating to statistical
Abstract An ice sheet always experience more or less melting during the summer. How much melting that occurs, is mostly determined by the albedo. Albedo is defined as the amount of the incoming shortwave radiation that gets reflected by a surface. When the sunlight starts melting the ice and snow in the summer, the albedo gets lower. The lower albedo itself causes more absorption of radiation, wh
Storms cause severe damages and cost lives. In order to assess the severity of storms, historical data sets such as reanalysis data can be employed. This kind of data is based on numerical weather prediction models. The realism of model data is limited by the spatial resolution of the model. A numerical weather prediction model is only as precise as its grid distance, meaning that a model cannot d
This thesis considers any existing representations of tragic themes in Plutarch's Lives of Demetrius and Antony. There is a modern debate regarding the nature of the tragic, which is initially adressed. The proposed themes are treated from the perspective of Plutarch's literary and moral intentions, namely the presentation of negative examples.
The present study investigated if the diagnostic value of cues could reduce the need for inhibition operating within the retrieval-practice paradigm, which is part of the retrieval-induced forgetting (RIF). The results of 32 participants (female: 20, age: M = 24.97 years, range: 20 – 32 years) were reported. The method used was a standard RIF procedure with an added manipulation. The category-item
This thesis analyzes Ecuadorian development through a historical perspective, in which the changes related to institutions and beliefs are crucial for the explanation of their dramatic transformation. In this respect, during most of its history Ecuador was characterized for lack of leadership, high external dependence, corruption, selfish interests of groups of power, and huge instability. Indeed,
Popular science summary: Understanding the bacterial cytoskeleton The bacterial cytoskeleton was discovered not too long ago. Since its discovery, it has been a source of information and understanding of how this essential cellular system is established and maintained. The cytoskeleton allows for subcellular organization, which is the key behind many cellular functions. One such function is pola
Secondary organic aerosol (SOA) mass yields were tested for six combinations of two anthropogenic volatile organic compounds (AVOC); m-xylene & toluene, and three biogenic volatile organic compounds (BVOC); α-pinene, myrcene & isoprene. The purpose was to investigate any non-additive results in SOA formation from mixtures of AVOCs and BVOCs by comparing experimental yield with correspondin
