  1. 1. Improving Behavior Trees that Use Reinforcement Learning with Control Barrier Functions : Modular, Learned, and Converging Control through Constraining a Learning Agent to Uphold Previously Achieved Sub Goals

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

    Author : Jannik Wagner; [2023]
    Keywords : Behavior Trees; Reinforcement Learning; Control Barrier Functions; Robotics; Artificial Intelligence; Verhaltensbäume; Verstärkendes Lernen; Kontrollbarrierefunktionen; Robotik; Künstliche Intelligenz; Beteendeträd; Förstärkningsinlärning; Kontrollbarriärfunktioner; Robotik; Artificiell Intelligens;

    Abstract : This thesis investigates combining learning action nodes in behavior trees with control barrier functions based on the extended active constraint conditions of the nodes and whether the approach improves the performance, in terms of training time and policy quality, compared to a purely learning-based approach. Behavior trees combine several behaviors, called action nodes, into one behavior by switching between them based on the current state. READ MORE

  2. 2. Safe autonomous lane-switching controller using high-order control barrier and Lyapunov functions

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

    Author : Arno Frauenfelder; [2023]
    Keywords : ;

    Abstract : With the rising interest in autonomous vehicles due to developments with electric cars and computer vision, controllers that provide safe, collision free manoeuvres are crucial for the advancement of this technology. In this thesis, a controller for autonomous vehicles for safe, collision-free lane switching on highways including adaptive cruise control is proposed. READ MORE

  3. 3. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Siddharth Selvarajan; [2021]
    Keywords : Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

    Abstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

  4. 4. Estimating Switching Costs in Electricity Retailing : Empirical Evidence from Sweden

    University essay from Umeå universitet/Nationalekonomi

    Author : Emil Björkman; [2021]
    Keywords : ;

    Abstract : In many situations, consumers face a cost for switching suppliers, either in monetary or in non-monetary terms. The cost associated with the switch is called switching cost and could lead to consumers that are locked-in to their current supplier. In the Swedish electricity retail market, evidence suggests that there are few switches of suppliers. READ MORE

  5. 5. HfO2 and ITO Resistive Random-Access Memory

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Mattias Åstrand; [2020]
    Keywords : RRAM; Resistive switching; HfO2; ITO; Physics and Astronomy;

    Abstract : The purpose of this work is of evaluating the choice of HfO2 and ITO as the dielectric and the top electrode in high performance resistive random-access memory (RRAM), respectively. The study is twofold, as it quantifies performance according to standard figures of merit for this technology, as well as provides insight into the physics of current conduction for this material choice.
