1. 16. Search for Higgs-like bosons through optimization of top-quark modelling

   Magister-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Rafael Antonio Lopez; [2021]
   Nyckelord :ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

   Sammanfattning : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. LÄS MER

3. 17. Assessment of Modern Statistical Modelling Methods for the Association of High-Energy Neutrinos to Astrophysical Sources

   Nyckelord :Statistics; Astrophysics; Neutrino sources; Mixture models; Monte Carlo methods; Maximum likelihood estimation; Statistik; Astrofysik; Neutrinokällor; Blandningsmodeller; Monte Carlo-metoder; Maximum likelihood-metoden;

   Sammanfattning : The search for the sources of astrophysical neutrinos is a central open question in particle astrophysics. Thanks to substantial experimental efforts, we now have large-scale neutrino detectors in the oceans and polar ice. LÄS MER

4. 18. Analys av osäkerheter vid hydraulisk modellering av torrfåror

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Simon Ene; [2021]
   Nyckelord :Hydraulic modeling; Uncertainty analysis; Sensitivity Analysis; Polynomial Chaos Expansion; Quasi Monte Carlo; OpenTURNS; TELEMAC-MASCARET; Hydraulisk modellering; Osäkerhetsanalys; Känslighetsanalys; Polynomial Chaos Expansion; Quasi Monte Carlo; OpenTURNS; TELEMAC-MASCARET;

   Sammanfattning : Hydraulisk modellering är ett viktigt verktyg vid utvärdering av lämpliga åtgärder för torrfåror. Modelleringen påverkas dock alltid av osäkerheter och om dessa är stora kan en modells simuleringsresultat bli opålitligt. Det kan därför vara viktigt att presentera dess simuleringsresultat tillsammans med osäkerheter. LÄS MER

5. 19. AI Trained to Predict Thresholds of 2D Ellipse Percolation Systems

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Nirav Surajlal; [2021]
   Nyckelord :Low-dimensional Nanomaterials; Percolation Threshold; Machine Learning; Regression; Two-dimensional Heterogeneous Ellipse System; Lågdimensionella nanomaterial; Perkolering Tröskel; Maskininlärning; Regression; Tvådimensionellt Heterogent Ellipssystem;

   Sammanfattning : Percolation theory is a relevant area of research in Nanotechnology because of its wide applications in nanoelectronics based on thin films of nanoparticles and composites, amongst others. In nanotechnology, systems are often explored through modelling and simulations. LÄS MER

7. 20. Accuracy of Risk Measures For Black Swan Events

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Viktor Barry; [2021]
   Nyckelord :Black swans; value at risk; conditional value at risk; monte carlo simulation; financial mathematics; risk analysis; financial risk; Black Swan; value at risk; conditional value at risk; monte carlo-simulering; finansiell matematik; riskanalys; finansiell risk;

   Sammanfattning : This project aims to analyze the risk measures Value-at-Risk and Conditional-Value-at-Risk for three stock portfolios with the purpose of evaluating each method's accuracy in modelling Black Swan events. This is achieved by utilizing a parametric approach in the form of a modified (C)VaR with a Cornish-Fisher expansion, a historic approach with a time series spanning ten years and a Markov Monte Carlo simulation modeled with a Brownian motion.
