  2. 1. Markov Chains, Renewal, Branching and Coalescent Processes : Four Topics in Probability Theory

    Author : Andreas Nordvall Lagerås; Thomas Höglund; Ingemar Kaj; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : This thesis consists of four papers.In paper 1, we prove central limit theorems for Markov chains under (local) contraction conditions. As a corollary we obtain a central limit theorem for Markov chains associated with iterated function systems with contractive maps and place-dependent Dini-continuous probabilities. READ MORE

  4. 2. Complexity-aware Decision-making with Applications to Large-scale and Human-in-the-loop Systems

    Author : Elis Stefansson; Karl H. Johansson; Henrik Sandberg; Iman Shames; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complexity-aware Decision-making; Automata Theory; Automatic Control; Optimal Control; Kolmogorov Complexity; Hierarchical Finite State Machines; Large-scale Systems; Human-in-the-loop; Game Theory; Human Decision-making; Autonomous vehicles; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis considers control systems governed by autonomous decision-makers and humans. We formalise and compute low-complex control policies with applications to large-scale systems, and propose human interaction models for controllers to compute interaction-aware decisions. READ MORE

  5. 3. On the Logic of Theory Change : Extending the AGM Model

    Author : Eduardo Fermé; John Cantwell; David Makinson; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Logic of Theory Change. AGM model. Belief Bases; Iterated Models; Multiple belief change; AGM and defeasible Logic; Logic; Logik;

    Abstract : This thesis consists in six articles and a comprehensive summary. • The pourpose of the summary is to introduce the AGM theory of belief change and to exemplify the diversity and significance of the research that has been inspired by the AGM article in the last 25 years. READ MORE

  6. 4. Growth, Accumulation, Crisis : With New Macroeconomic Data for Sweden 1800-2000

    Author : Rodney Edvinsson; Karl Gratzer; Satya Datta; Olle Krantz; Jan Bohlin; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GDP; employment; national accounts; Sweden; crisis; growth; capital; capitalism; accumulation; profit; surplus; economic history; growth theory; Marxism; long wave theory; business cycle; depression; recession; Economic history; Ekonomisk historia;

    Abstract : This dissertation has two main objectives. The first one is to construct historical macroeconomic series for Sweden using a consistent method throughout the relevant periods, and which rely on modern methods of national accounting. READ MORE

  7. 5. Online trajectory planning and observer based control

    Author : David A. Anisi; Xiaoming Hu; Daizhan Cheng; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Consensus Problem; Simultaneous Arrival; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : The main body of this thesis consists of four appended papers. The first two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. READ MORE
