  1. 1. Geometry of high dimensional Gaussian data

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Olof Samuel Mossberg; [2024]
    Keywords : HDLSS; high dimensional data; stochastic boundedness; asymptotic orthogonality; geometry; multivariate normal distribution; HDLSS; högdimensionell data; stokastisk begränsning; asymptotisk ortogonalitet; geometri; multivariat normalfördelning;

    Abstract : Collected data may simultaneously be of low sample size and high dimension. Such data exhibit some geometric regularities consisting of a single observation being a rotation on a sphere, and a pair of observations being orthogonal. This thesis investigates these geometric properties in some detail. READ MORE

  2. 2. Stochastic Optimization of Asset Management Project Portfolios: A Risk-Informed Approach

    University essay from KTH/Matematik (Avd.)

    Author : Sebastian Persson; Niklas Hansson; [2023]
    Keywords : Nuclear asset management; Risk-informed asset management; Portfolio optimization; Project selection; Knapsack problem; Monte Carlo simulation; Conditional Value at Risk; Tillgångsförvaltning; Riskinformerad tillgångsförvaltning; Portföljoptimering; Projekturval; Kappsäcksproblem; Monte Carlo simulering; Conditional Value at Risk;

    Abstract : Asset management within the nuclear industry has become an increasingly relevant topic as safety requirements have tightened and energy security has become more important. Asset management ensures performance and reliability in a nuclear facility by balancing costs, opportunities, and risks to get the most out of assets. READ MORE

  3. 3. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

    University essay from KTH/Optimeringslära och systemteori

    Author : Max Völcker; Hugo Rolff; [2023]
    Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

    Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE

  4. 4. When is Electric Freight Cost Competitive? : Computational modeling and simulation of total cost of ownership for electric truck fleets

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Author : Anton Zackrisson; [2023]
    Keywords : electric freight; battery-electric trucks; total cost of ownership; decision making under deep uncertainty DMDU ; cost-competitiveness; exploratory modeling and analysis EMA ; EMA workbench; quasi-Monte Carlo method; VRP; EVRP; elektrifiering; godstransport; elektriska lastbilar; total ägandekostnad; kostnadskonkurrenskraft; ruttoptimering;

    Abstract : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.

  5. 5. Models for solid waste and its management in Stockholm metropolitan area

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lars Arvidsson; Kasper Nordenram; [2022]
    Keywords : ;

    Abstract : In the transition from a linear economy to a sustainable circular economy, waste management is critical. This thesis approaches the management of Municipal Solid Waste (MSW) from the perspective of a mathematical modelling. Within the scope of the thesis, three mathematical models were developed.
