1. 1. Data-Driven Learning for Approximating Dynamical Systems Using Deep Neural Networks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Axel Dernsjö; Max Berg Wahlström; [2021]
   Keywords : ;

   Abstract : In this thesis, a one-step approximation method has been used to produce approximations of two dynamical systems. The two systems considered are a pendulum and a damped dual-mass-spring system. READ MORE

3. 2. Universality and Individuality in Recurrent Networks extended to Biologically inspired networks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nishant Joshi; [2020]
   Keywords : Recurrent Neural Networks; rate Networks; Fixed Points; Dynamical Systems; Leaky Integrate and Fire; Computational Neuroscience;

   Abstract : Activities in the motor cortex are found to be dynamical in nature. Modeling these activities and comparing them with neural recordings helps in understanding the underlying mechanism for the generation of these activities. For this purpose, Recurrent Neural networks or RNNs, have emerged as an appropriate tool. READ MORE

4. 3. Modeling the Dynamics of Opinion Change : when Individuals may have Different Overt and Covert Opinions

   University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

   Author : Nour Kaisso; [2019]
   Keywords : mathematical modeling of attitude change; overt and covert opinions; dynamics of opinion change in society; social desirability bias; cognitive dissonance;

   Abstract : This thesis aims to present and explore a mathematical model of attitude change within society. Building on the foundations set up by Lave and March [2] and Eriksson and Strimling [1] we propose a model which includes the possibility of having an overt as well as covert opinion by any individual on a given issue.

5. 4. Application of Polynomial Chaos Expansion for Climate Economy Assessment

   University essay from KTH/Optimeringslära och systemteori

   Author : Robin Nydestedt; [2018]
   Keywords : ;

   Abstract : In climate economics integrated assessment models (IAMs) are used to predict economic impacts resulting from climate change. These IAMs attempt to model complex interactions between human and geophysical systems to provide quantifications of economic impact, typically using the Social Cost of Carbon (SCC) which represents the economic cost of a one ton increase in carbon dioxide.

6. 5. Properties of a generalized Arnold’s discrete cat map

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Fredrik Svanström; [2014]
   Keywords : Arnold’s discrete cat map; Hyperbolic toral automorphism; Discrete-time dynamical systems; Poincaré recurrence theorem; Number theory; Linear algebra; Fibonacci numbers; Pell numbers; Cryptography;

   Abstract : After reviewing some properties of the two dimensional hyperbolic toral automorphism called Arnold's discrete cat map, including its generalizations with matrices having positive unit determinant, this thesis contains a definition of a novel cat map where the elements of the matrix are found in the sequence of Pell numbers. This mapping is therefore denoted as Pell's cat map. READ MORE
