High energy particle collisions involve complex physics, beyond analytical control. Instead, Monte Carlo event generators like Pythia have been used to simulate particle collisions since decades. A study of the production of heavy quarks (namely, charm and bottom) is presented for two different scenarios: lepton (e+e−) and hadron (pp) collisions. Electron- positron collisions at the Z0 resonance a
There are many old buildings in Sweden today that in many aspects are worth saving for the future. Much focus is also on how to reduce the energy use in buildings. This theoretical study tries to give an example on that it is possible to combine these two parameters without risking the physical wellbeing or the aesthetic value of the building. The house in this report is situated in Vä, a communit

Syftet med denna uppsats är att öka förståelsen om konsumenters förtroende för en tjänsteverksamhet till följd av en omreglering. För att kunna besvara detta syfte kommer följande två frågeställningar besvaras; > Vad påverkar konsumenters förtroende för en apoteksverksamhet? > Och hur uttrycks detta hos konsumenter? Metod: Uppsatsen tillämpar en genomgående kvalitativ ansats där en abduktiv m
Följande uppsats är skriven på uppdrag av Länsstyrelsen i Gotlands län med syfte att tillämpa GIS för att identifiera lämpliga områden för kontrollerad naturvårdsbränning. Skogsbränder, både naturliga och antropogena, har historiskt varit en frekvent närvarande störningsregim i den svenska skogen. Branden har bidragit till att skapa stora delar av de strukturer och den biologiska mångfald som finnThis study was conducted on behalf of the county administrative board of Gotland, with the aim of using Geographical Information systems to identify protected forest areas where controlled fires would be suitable to incorporate in management plans. Forest fire, being both a natural and cultural phenomenon has historically been a frequently recurrent disturbance regime in the boreal and boreonemora
Image quality is in essence based on subjective experience, and the involvement of human subjects is therefore necessary in one way or the other in order to make reliable assessments of it. This topic is of interest for Axis Communications AB -- the market leader in surveillance cameras. In this thesis, the softcopy quality ruler method described in ISO 20462 is evaluated through a study of one s
Popular science summary: Bolder the brighter – personality affects learning performance in crucian carp Just as humans, many animals have a personality. For example some individuals are more prone to take risks – they are bold, while others prefer to play it safe – being shy. Bold animals increase their risk of being attacked by a predator but may also receive higher gains by being first to a foAbstract Gathering information about the environment is crucial to living organisms as it makes up the foundation upon which decisions are made. In a diverse environment a huge amount of information sources arise. An individual can choose to follow other’s decision (social information use) or to gather its’ own information. Which sources are used and how well they are perceived vary between indi
Forecasting foreign exchange rates and financial asset prices in general is a hard task. The best model has often been shown to be a simple random walk, which implies that the price movements are unpredictable. In this thesis models that have been somewhat successful in the past are developed and investigated for different forecasting horizons. The aim is to find models that significantly dominate
Transitional economies tend to see trade liberalization and capital reforms hand in hand. The main goal or aim for lawmakers is to maximize welfare effects when bringing trade and capital reforms within an economy. A nation gets greater access to international financial markets, which in turn attracts inflow of investments within economy. This newfound inflow of investments can also be attributed
One of the topics that has generated discussions and focuses on demographic theory is undoubtedly the treatment of fertility rates, another important number of studies have incorporated different methods for measuring behaviors in count data, such as Poisson models, also used in the present document. On the other hand, by using panel data, we estimate a random effects model and evaluate the dete
The paper examines the extent to which role-based access control is used within organizations to control and assign access rights to users. Furthermore, this paper investigates whether organizations are aware of security risks that arise when users are assigned too many or incorrect access rights and the steps they take to reduce the problem. The survey was conducted through the collection of qual
This paper discusses what the transfer of white trash from the US to Sweden means; how did it happen, why did it happen and what are the swedish interpretation of the concept? The concept of white trash include both pride and dirt; it frames an anomaly composed of bad taste and a dangerous body. But it is also a subject of creating identities and making fun. The journey to Sweden should be seen in
Whether a law implementation can be said to have had an social impact is largely dependent on if the law in question effected the minds of the people it was tasked to govern. Previous research of successful implementation of laws identify the importance of certain conditions to be present if a law is to be termed “successful”. A law implementation that has been recognized as having had a marked ef
This paper investigates the characteristics and history of value added taxes. Many previous studies have focused on the theoretical implications of value added taxes; this paper differs in the method used as well as the phrasing of research question. This paper seeks out to answer whether a redesign of the current Value Added Tax system in Sweden could be a Pareto improvement. It looks at relevant
In this thesis a method for decomposing QCD colour structures into multiplet bases is described. The method is applicable for any number of gluons and quarks. To achieve the decomposition requires the knowledge of group theoretical weights, so-called Wigner 3j and 6j coefficients. The number of required coefficients have been calculated for up to 12 external gluons, and been shown to scale well in
The big risk topic in recent years, in the nancial industry, has been about capital requirements. The nancial crisis in 2008 displayed several shortcoming regarding weak capital buers in banks. After that crisis big eorts have made sure that the capital buers have been improved drastically over Europe. Now another issue is starting to worry nancial regulators in Europe regarding the quality of ban
In this thesis, we study the problem of predicting users' media preferences based on their, as well as other users' historical rating data. The model used is that a user's rating for an item can be explained by a sum of bias terms and an inner product between two vectors in some multidimensional feature space that is specic to the product domain. This model is tted using a stochastic d
Abstract The long-term aim of this project was to develop synbiotic drinks presenting food supplements with beneficial effects on human health. A synbiotic consists of a combination of probiotic bacteria and one or more prebiotics. For the part of the project that was covered by this Master thesis, a probiotic strain, Lactobacillus plantarum F44 and a prebiotic galactooligosaccharide (GOS) were t
