  1. 1. A Markovian Approach to Financial Market Forecasting

    University essay from KTH/Matematisk statistik

    Author : Kevin Sun Wang; William Borin; [2023]
    Keywords : Markov chain; Markov model; stock market prediction; Laplace smoothing; steady-state; forecasting; trading strategy; stochastic; trading algorithm; Markovkedjor; Markovmodell; prediktion; Laplace-jämning; stationär fördelning; tradingstrategi; stokastisk; trading algoritm;

    Abstract : This thesis aims to investigate the feasibility of using a Markovian approach toforecast short-term stock market movements. To assist traders in making soundtrading decisions, this study proposes a Markovian model using a selection ofthe latest closing prices. READ MORE

  3. 2. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data

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

    Author : Alfred Nilsson; [2023]
    Keywords : Deep Learning; Vision-Transformers; Echocardiography; Feature Selection; Gumbel-Softmax; Concrete Autoencoders; Regression; Djupinlärning; Vision-Transformers; Ekokardiografi; Feature Selection; GumbelSoftmax; Concrete Autoencoders; Regression;

    Abstract : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. READ MORE

  4. 3. 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. 4. Stochastic Adaptive Robust Approach in the Optimal Bidding Behavior of a Virtual Power Plant in the Multi-Market Setup

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

    Author : Nina Manivong; [2022]
    Keywords : Robust optimization; stochastic programming; strategic offering; uncertainty; virtual power plant; hydro-power; wind; storage; Robust optimering; stokastisk programmering; strategiskt erbjudande; osäkerhet; virtuellt kraftverk; vattenkraft; vindkraft; lagring;

    Abstract : Hydropower in Sweden is a powerful and efficient source of energy due to its flexibility, usually used to balance the Swedish power system. With the transition of power system into more intermittent power sources, the role of hydro-power as producers will become more important. READ MORE

  6. 5. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE
