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

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  2. 2. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

  3. 3. Assessment of Groundwater Flow to Lake Bolmen

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Author : Massimiliano Favaro; [2021]
    Keywords : Groundwater; modelling; MODFLOW; GMS; hydrogeology; Technology and Engineering;

    Abstract : This work reports the research and findings concerning the processes of groundwater flow and distribution to lake Bolmen in the Småland region, Sweden. The watershed of Bolmen is of high interest since it provides water for drinking and energy purposes, representing a resource of notable importance for the society of southern Sweden. READ MORE

  4. 4. Deligate’s role and impact in the food system : a case study of a Swedish company’s multifaceted approach to tackle avoidable food waste in the retail sector

    University essay from SLU/Department of Molecular Sciences

    Author : Chelsea Hoegberg; Amanda Olsson; [2021]
    Keywords : circularity broker; consumer behavior; consumer engagement; food system; food waste; price reduction; retail sector;

    Abstract : Food waste is occurring at all stages of the food supply chain and leading to environmental, economic, and social costs and injustices. While some actors are responsible for greater degrees of waste, every actor is being called upon to take action. READ MORE

  5. 5. Forecasting with deep temporal hierarchies : A novel way for forecasting with temporal hierarchies based on deep learning models

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Filotas Theodosiou; [2021]
    Keywords : Forecasting; temporal hierarchies; forecast reconciliation; hierarchical forecasting; machine learning; deep learning;

    Abstract : Temporal hierarchies are being increasingly used for forecasting purposes over the past years. They have been shown to produce accurate and coherent forecasts which are beneficial for enterprises. Reconciling forecasts of different aggregation levels to achieve coherence, supports aligned decisions between different organizational levels. READ MORE
