  1. 1. Solving Ordinary Differential Equations and Systems using Neural Network Methods

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mimmi Westrin; [2023]
    Keywords : Neural network methods; trial solutions; numerical methods; Lotka-Volterra system; SEIR model;

    Abstract : The applications of differential equations are many. However, many differential equations modelling real-world scenarios are very complex and it can be of great difficulty to find an exact solution if one even exists. Thus, it is of importance to be able to approximate solutions of differential equations. READ MORE

  3. 2. Analysis and Implementation of Adaptive Explicit Two-Step Methods

    University essay from Lunds universitet/Matematik LTH

    Author : Kjartan Kari Gardarsson Myrdal; [2015]
    Keywords : numerical methods; two-step; variable; multistep methods; ODE; adaptive; differential equations; parametric; explicit; Mathematics and Statistics;

    Abstract : Recently a new way of constructing variable step-size multistep methods has been proposed, that parametrizes the entire domain of multistep methods. In the presented work the case of explicit two-step methods is looked at, analyzed and related to the already known theory of multistep methods. READ MORE

  4. 3. On an epidemic model given by a stochastic differential equation

    University essay from Matematiska och systemtekniska institutionen

    Author : Zarife Zararsiz; [2009]
    Keywords : Epidemics models; stochastic differential equations; Lotka-Volterra equations; scale measure; speed measure; limiting distributions; reflecting boundaries; killed processes;

    Abstract : We investigate a certain epidemics model, with and without noise. Some parameter analysis is performed together with computer simulations. The model was presented in Iacus (2008). . READ MORE
