  1. 16. Model Predictive Climate Control for Electric Vehicles

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Erik Norstedt; Olof Bräne; [2021]
    Keywords : MPC; model predictive control; climate control; electric vehicle; battery; thermal management; electrified vehicle; battery electric vehicle; nonlinear MPC; custom cost functions; elfordon; temperaturreglering;

    Abstract : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

  3. 17. Inverse Uncertainty Quantification using deterministic sampling : An intercomparison between different IUQ methods

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Hjalmar Andersson; [2021]
    Keywords : Inverse Uncertainty Quantification; Model calibration; Unscented transform; Deterministic sampling;

    Abstract : In this thesis, two novel methods for Inverse Uncertainty Quantification are benchmarked against the more established methods of Monte Carlo sampling of output parameters(MC) and Maximum Likelihood Estimation (MLE). Inverse Uncertainty Quantification (IUQ) is the process of how to best estimate the values of the input parameters in a simulation, and the uncertainty of said estimation, given a measurement of the output parameters.

  4. 18. The Black-Litterman Asset Allocation Model - An Empirical Analysis of Its Practical Use

    University essay from KTH/Matematik (Avd.)

    Author : Hampus Ernstsson; Max Börjes Liljesvan; [2021]
    Keywords : Black-Litterman model; asset allocation; portfolio optimization; investor views; portfolio management; Black-Litterman model; tillgångsallokering; portföljoptimering; investerarens förväntade avkastningar; portföljförvaltning;

    Abstract : Modern portfolio theory has its attractive characteristics of promoting diversification in a portfolio and can be seen as an easy alternative for setting optimal weights for portfolio managers. Furthermore, as portfolio managers try to beat a defined benchmark for their portfolio the Black-Litterman model allows them to include their own prospects on the future return of markets and securities.

  5. 19. Childhood Habituation in Evolution of Augmenting Topologies (CHEAT)

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Anton Moberg; [2020]
    Keywords : Neuroevolution; genetic algorithm; machine learning; ML; CHEAT; Childhood Habituation in Evolution of Augmenting Topologies; optimization; artificial neural network; self evolving; model selection; Physics and Astronomy;

    Abstract : Neuroevolution is a field within machine learning that applies genetic algorithms to train artificial neural networks. Neuroevolution of Augmenting Topologies (NEAT) is a method that evolves both the topology of the network and trains the weights of the network at the same time, and has been found to successfully solve reinforcement learning problems efficiently and the XOR problem with a minimal topology.
