The report aims at quantifying vulnerability of lakes by multiple linear regression, in which transparency of the water is used as a proxy for vulnerability and parameters such as area and depth of the lake as independent descriptors. Data was acquired from Swedish environmental monitoring programs. The analysis results in a model that can be used to predict this trend and thus predict the vulnera
The grocery market in Sweden is mainly divided between six different retailers who together have some 95% market share. The rest of the market is divided between thousands of different actors, selling groceries in other ways than the main retailers. This 5% market is interesting to investigate and the purpose is to identify the opportunities and barriers for those alternative food distributers. B
Purpose: The purpose of this paper is to empirically evaluate the performance of seven different methods that are used when estimating Value-at-Risk for a portfolio of Swedish index-bonds with different maturities. As a supplementary objective, the paper tries to determine the history that one needs to account for when calculating VaR. Methodology: In order to calculate the VaR, a portfolio consi
During the process of its socio-economic development, Vietnam has been achieving the remarkable successes in poverty reduction, and the economic growth that is recognized by the World Bank, the Asian Development Bank and the international communities. However, the fast industrialization and urbanization are attracting the increasing inflow of rural migrants to urban areas. Besides that, the govern
Populärvetenskaplig sammanfattning. Katalyskammare för aktivitetsmätning med laser. Katalysatorer är oumbärliga i såväl livsprocesser som industriella tillämpningar. Bilismen är ett exempel där katalysatorer används vid såväl bränsletillverkning som avgasrening. Med hänsyn till miljön måste mycket ständigt förbättras, också katalytiska processer. I mitt examensarbete har jag karakteriserat en ny Industrial catalysts are very complex systems, often produced of nanoparticles dispersed in a so-called support material to maximize the surface area and minimize the cost. These catalysts are very difficult to study in surface science. Therefore industrial catalysts have been developed in a trial-and-error approach, with the loss of the fundamental understanding of the reactions. In surface scien
How many times have you heard that if children are in church they should be quiet and still? It was common to hear when I was young that children should go out as soon as they started making any noise. It was and is always a pleasure for everyone to hear the cute children singing a pretty song in church but afterwards there should be silence again! What I want is for the congregation to accept the
