1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

2. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control
University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE

3. A Comparison of Statistical Methods to Generate Short-Term Probabilistic Forecasts for Wind Power Production Purposes in Iceland
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Accurate forecasts of wind speed and power production are of great value for wind power producers. In Southwest Iceland, wind power installations are being planned by various entities. READ MORE

4. Verification of the local similarity theory above forests
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

5. On the Identification of Nonlinear Optima in Spatially Developing Boundary Layer Flow
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : The present thesis studies transition to turbulence in a spatially developing bound-ary layer for subcritical Reynolds numbers. A fully nonlinear iterative direct-adjoint optimisation technique is employed to identify finite amplitude perturbations triggering transition in an energy efficient way. READ MORE
