1. 21. Fitting the three loop pion mass and decay constant to lattice data

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Alexandra Wernersson; [2019]
   Keywords : Chiral Perturbation Theory; Lattice QCD; pion mass; decay constant; three loop fit.; Physics and Astronomy;

   Abstract : We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. READ MORE

3. 22. Quenching a steel plate by water - impinging jets and different simultaneous flow rates

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Pablo Martinez; [2019]
   Keywords : Quenching; steel; plate; cooling; water- impinging jets; cooling rate; subcooling; temperature.;

   Abstract : Regarding the great importance of fast cooling in steel industry for the production processes, a deep understanding of heat transfer and fluid dynamics must be held. A steel plate is heated up until a maximum temperature of 700 ⁰ C to be the n cooled down seconds later by a configuration of multi ple impinging water jets. READ MORE

4. 23. Outlier-Robust Dynamic Portfolio Optimization based on Bear-Bull-Regimes

   University essay from Lunds universitet/Matematisk statistik

   Author : Emil Eliasson; Linus Hamlin; [2018]
   Keywords : Mathematics and Statistics;

   Abstract : The work in this thesis is meant to improve an existing algorithm described in Nystrup (2017). As the original model uses a normal distribution to approximate the daily logarithmic returns, the authors of this thesis aim to improve the approximation by using Student’s t-distribution which may be a better approximation of financial data.

5. 24. How Google Search Trends Can Be Used as Technical Indicators for the S&P500-Index : A Time Series Analysis Using Granger’s Causality Test

   University essay from KTH/Matematisk statistik

   Author : Albin Granell; Filip Carlsson; [2018]
   Keywords : ;

   Abstract : This thesis studies whether Google search trends can be used as indicators for movements in the S&P500 index. Using Granger's causality test, the level of causality between movements in the S&P500 index and Google search volumes for certain keywords is analyzed. READ MORE

6. 25. Analysis of urban ecosystem condition indicators for the large urban zones and city cores in EU : threshold assessment and exploration of the relation to ecosystem services through the application of G.I.S

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Christina Kourdounouli; [2018]
   Keywords : geography; GIS; EU; urban atlas; larger urban zone; city core; urban ecosystem; ecosystem condition indicator; urban green space; impervious surface; natural area; agricultural area; protected area; abandoned area; number of inhabitants per area; artificial area per inhabitant; urban ecosystem condition indicator thresholds; ecosystem services; recreation opportunity spectrum; NO2 removal by urban vegetation; urban heat island effect; cluster analysis; precipitation; temperature; climate adaptation; Earth and Environmental Sciences;

   Abstract : As almost three out of four EU citizens live in urban areas and this number is expected to further grow, studies on urban ecosystems and their services are crucial to understand a city’s environmental structure and capabilities. The European Commission has published a relative report which suggests an urban ecosystem condition indicator framework, yet without suggesting respective thresholds that might indicate a “desired” environmental condition of the city.
