1. 6. Simulating Microwave Heating for Industrial Processes Using the Finite-Difference Time-Domain Method

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Dante Grenholm; Axel Nilsson; Linus Olofsson; Oskar Pettersson Löfstedt; [2022]
   Nyckelord :Microwave oven; Heating; Simulation; Mikrovågsugn; Uppvärmning; Simulering;

   Sammanfattning : Microwave heating is an efficient way of heating compared to conventional industrial alternatives such as autoclaves, a type of pressure cooker commonly used for curing and sterilisation. One problem that limits the adoption of microwave ovens in industrial processes is uneven heating. LÄS MER

3. 7. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines

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

   Författare :Shilin Zhao; [2021]
   Nyckelord :Dielectric frequency response; End corona protection; Finite element method; High voltage rotating machines; Stator insulation; Dielektrisk frekvensrespons; Ändglimmskydd; Finita element metoden; Högspänningsmaskiner; Statorisolering;

   Sammanfattning : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. LÄS MER

4. 8. Fourth-Order Runge-Kutta Method for Generalized Black-Scholes Partial Differential Equations

   Kandidat-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

   Författare :Sidra Tajammal; [2021]
   Nyckelord :Generalized Black-Scholes partial differential equations; Finite difference methods; Fourth-Order Runge-Kutta method; Stability and Convergence;

   Sammanfattning : The famous Black-Scholes partial differential equation is one of the most widely used and researched equations in modern financial engineering to address the complex evaluations in the financial markets. This thesis investigates a numerical technique, using a fourth-order discretization in time and space, to solve a generalized version of the classical Black-Scholes partial differential equation.

5. 9. Numerical simulations of the Dynamic Beam Equation in discontinuous media

   Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Niklas Wik; David Niemelä; Valter Wagner Zethrin; [2020]
   Nyckelord :Dynamic beam equation; DBE; SAT; projection; SBP;

   Sammanfattning : The study examines the Projection method and the simultaneousapproximation-term (SAT) method as boundary treatment for the dynamic beam equation using summation-by-parts (SBP) operators for handling the inner domain. The methods are examined for both the homogeneous constant coefficient case, and the inhomogeneous piecewise constant coefficient case with a coupled interface. LÄS MER

7. 10. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

   Författare :David Anguiano Sanjurjo; [2020]
   Nyckelord :5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

   Sammanfattning : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.
