1. 1. Correction of Inhomogeneous Data in the Precipitation Time Series of Sweden Due to the Wind Shield Introduction

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Ioannis Sofokleous; [2016]
   Keywords : Precipitation data correction; precipitation time series; homogenization of precipitation data; wind shield; wind screen; aerodynamic wind error; Nederbördsdatakorrektion; nederbörds tidsserier; inhomogena nederbördsdata; vindskydd; vindskärm; aerodynamiska vindfel;

   Abstract : The work of this master thesis is based on analyses of monthly precipitation data from 70 stations of the SMHI (Swedish Meteorological and Hydrological Institute) in Sweden, in the period 1860-2014, using the information for the year of introduction of the wind shield at each station. The primary goal is the calculation of correction factors which will be applied on the precipitation data in the period of measurements before the introduction of the wind shield. READ MORE

3. 2. Austenite grain growth in bearing steels : An investigation on steel grades 100Cr6 and 100 CRMnMoSi8-4-6

   University essay from KTH/Materialvetenskap

   Author : Erik Persson; [2014]
   Keywords : Grain growth; Grain size;

   Abstract : An investigation of austenite grain growth of two bearing steel grades; 100Cr6 and100CrMnMoSi8-4-6 is performed. Austenitization treatments were performed between 860°C and 1200 °C for 5 minutes to 5 hours and the grain size was determined for each sample.Grain boundary etching was carried out using a water based, picric-acid etchant.
