1. 1. An agent-based model approach to computational epidemiology

   Kandidat-uppsats, KTH/Datavetenskap

   Författare :Max Wiktorsson; Emil Franzell; [2022]
   Nyckelord :;

   Sammanfattning : The aim of this work was to compare different Non-pharmaceutical interventions (NPIs) in a simulated environment modeling Sweden with 10 000 000 (ten million) agents. Simulating the performance of these NPIs can be beneficial to policymakers and other government officials in order to give the power to make the right decision in the face of an epidemic. LÄS MER

   Sammanfattning : Modelling and simulation of complex and multi-domain mechanical systems has become of major importance in the last few years to address energy and fuel consumption performance evaluation. The goal is to unify the available modelling languages aiming to improve scalability and easiness of handling complex multi-domain models. LÄS MER

4. 3. Numeriska fouriertransformen och dess användning : En introduktion

   Kandidat-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Kristoffer Tondel; [2022]
   Nyckelord :Fast Fourier Transform; FFT; Discrete Fourier transform; DFT; Scientific Computing; Partial differential equation; PDE; Williamsons Runga-Kutta; Fast Fourier Transform; FFT; Diskreta fouriertransformen; DFT; Beräkningsmatematik; Partiella differential ekvation; PDE; Williamsons Runga-Kutta;

   Sammanfattning : The aim of this bachelor's thesis is to use three variants of the discrete Fourier transform (DFT) and compare their computational cost. The transformation will be used to numerically solve partial differential equations (PDE). In its simplest form, the DFT can be regarded as a matrix multiplication. LÄS MER

5. 4. Parameter estimation in a cardiovascular computational model using numerical optimization : Patient simulation, searching for a digital twin

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

   Författare :Giulia Tuccio; [2022]
   Nyckelord :Parameter estimation; Enhanced Scatter Search; Particle Swarm; Hooke and Jeeves; Cardiovascular Models; Parameteruppskattning; förbättrad spridningssökning; Particle Swarm; Hooke och Jeeves; kardiovaskulära modeller;

   Sammanfattning : Developing models of the cardiovascular system that simulates the dynamic behavior of a virtual patient’s condition is fundamental in the medical domain for predictive outcome and hypothesis generation. These models are usually described through Ordinary Differential Equation (ODE). LÄS MER

7. 5. Physics-informed Neural Networks for Biopharma Applications

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Linnéa Cedergren; [2021]
   Nyckelord :PINN; PINNs; physics-informed neural networks; neural networks; machine learning; sartorius; CSTR;

   Sammanfattning : Physics-Informed Neural Networks (PINNs) are hybrid models that incorporate differential equations into the training of neural networks, with the aim of bringing the best of both worlds. This project used a mathematical model describing a Continuous Stirred-Tank Reactor (CSTR), to test two possible applications of PINNs. LÄS MER
