In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

Today is one of the reasons that Sweden works for improved public health to reduce the incidence of the most common diseases. The eleven objectives are the key determinants of public health work and are thus assigned as the common positions for players to work towards the same goal.

Searches have been conducted in the databases SAGE Journals Online, ASSIA and Cinahl.
