1. 1. Synthesizing of brain MRE wave data

   University essay from KTH/Medicinsk avbildning

   Author : Maryia Yuliuhina; [2023]
   Keywords : MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

   Abstract : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. READ MORE

3. 2. Implementation and study of boundary integral operators related to PDE:s in the plane

   University essay from Lunds universitet/Matematik LTH

   Author : Erik Andersson; [2023]
   Keywords : Boundary integral equation; Singular integral operator; Product integration; Close evaluation; Numerical integration; MATLAB; Mathematics and Statistics;

   Abstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

4. 3. Modeling self-heating and dry matter loss in large-scale biomass storage

   University essay from KTH/Kemiteknik

   Author : Johan Qviström; [2022]
   Keywords : Modell; biomass; storage; self-heating; dry matter loss; Modell; biomassa; förvaring; uppvärmning; torrsubstansförlust;

   Abstract : Materialförluster och självuppvärmning är ett vanligt problem vid lagring av biomassa i stor skala. Biomassan som lagras bryts med tiden ned av mikroorganismer och kemiska processer vilket resulterar i en förlust av torrsubstans, ofta kring 1-4% per månad. READ MORE

5. 4. Simulation of Transformer Inrush Currents and Their Impact on the Grid

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Juan de la Peña Toledo; [2022]
   Keywords : Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

   Abstract : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. READ MORE

6. 5. Modeling The Temperature of a Calorimeter at Clab : Considering a Thermodynamic Model of The Temperature Evolution of The Calorimeter System 251

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Johannes Ekman; [2021]
   Keywords : calorimetry; calorimeter; System 251; temperature evolution; spent nuclear fuel; SNF; MATLAB; SERPENT2; Clab; nuclear decay heat; calibration measurements; thermodynamic model; gamma escape fraction; mass correction; calibration measurements; electric heater; three component system; system of ordinary differential equations; eigenvalues; eigenvalue estimation; temperature increase method; polynomial approximation of mass correction; sensitivity of mass correction; calorimeter heat capacity; mass correction uncertainty; calorimeter calibration curve; monoenergetic gamma spectrum; curve fitting of temperature as function of time;

   Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE
