1. 1. Soil Improvement method by Mass Stabilization : Settlement analysis in stabilized sulfide soil

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Albin Åkerlund; [2023]
   Nyckelord :Mass stabilization; Sulfide soil; settlement.;

   Sammanfattning : Mass stabilization is not a common soil improvement method in Sweden, and even less so in sulfide soils. Previous research indicates that a linear elastic material model is suitable for settlements in stabilized sulfide soil. A construction project in the northern part of Sweden applied mass stabilization in sulfide soil. LÄS MER

3. 2. Submillimeter 3D surface reconstruction of concrete floors

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Björn Hagström; Hampus Wallström; [2022]
   Nyckelord :Submillimeter; Structured light; Sinusoidal phase shift; Concrete; Surface reconstruction; Defocused binary pattern;

   Sammanfattning : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.

4. 3. Beyond Mean-Field Description of Bose-Einstein Condensate

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Daniel Larsson Persson; [2021]
   Nyckelord :Bose-Einstein condensate; BEC; dilute; non-uniform; quantum depletion; second quantisation; mean field; mean-field approximation; the Gross-Pitaevskii equation; Gross-Pitaevskii; perturbation theory; many-body perturbation theory; Rayleigh-Schrödinger perturbation theory; Rayleigh-Schrödinger; Epstein-Nesbet perturbation theory; Epstein-Nesbet; quantum ring; Physics and Astronomy;

   Sammanfattning : This thesis work is on the theoretical description of dilute Bose-Einstein condensates (BEC) that are non-uniform, meaning that more than one single-particle state is occupied. This phenomenon is usually called quantum depletion. LÄS MER

5. 4. Deep Learning for Dynamic Portfolio Optimization

   Master-uppsats, KTH/Matematisk statistik

   Författare :Victor Molnö; [2021]
   Nyckelord :Dynamic portfolio optimization; No-trade-region; Deep learning; Policy iteration; Dynamisk portföljoptimering; Handelsstoppregion; Djupinlärning; Policyiterering;

   Sammanfattning : This thesis considers a deep learning approach to a dynamic portfolio optimization problem. A proposed deep learning algorithm is tested on a simplified version of the problem with promising results, which suggest continued testing of the algorithm, on a larger scale for the original problem.

7. 5. Simulation of Leachate Generation from a Waste Rock Dump in Kiruna Using HYDRUS-1D

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Aryani Atmosudirdjo; [2019]
   Nyckelord :Hydrus-1D; matrix flow; leachate; unsaturated flow; waste rock dump;

   Sammanfattning : The percolation of water through waste rock dumps at mine sites can lead to the production of a leachate with high concentrations of dissolved metals, sulfate and nitrogen compounds. It is important to understand how water flows in waste rock dumps in order to predict the environmental impact of this leachate on recipients. LÄS MER
