The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. The system studied is a two-echelon system with one central warehouse and a number of local sites,

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

Protein MIG, from Streptococcus dysgalactiae, binds alpha2-macroglobulin and immunoglobulin G (IgG). MIG-derived fusion proteins with one to five IgG-binding repeats differed up to 72,000- fold in avidity for goat IgG, indicating a considerable cooperativity of the repeats. Significant sequence variation in the IgG-binding repeats was recognized. Protein MIG interacted with goat IgG1 via both the

Popular Abstract in English Fuel cells have been considered as alternative power source to petroleum oil. Especially, fuel cells have potentials to provide no pollutant emission (e.g., CO2, NOx, SOx) out of the power generation. For instance, once the fuel cells are installed instead of combustion engine in the cars used for commuting, transportation and leisure, the amount of pollutant emission cFuel cells are considered as a promising alternative environmentally benign power source to the existing ones depending on petroleum oil. Especially, proton-exchange membrane fuel cells (PEMFCs) have been intensively developed during the last decade because of their wide application windows including various portable, stationary and transportation applications. The market has been and will be main

This paper seeks to provide insight on the status and fertility of e-voting as a leveling agent in the municipalities of Haparanda and Botkyrka, which has the lowest voter turnout in Sweden. Through quantitative surveys in the townships, and further interviewing the development manager of the Swedish election committee. The collected material on e-voting was tested on parts of the rational choice
