  2. 21. Partitioning and Control for Dynamical Systems Evolving on Manifolds

    Author : Xiao Tan; Dimos V. Dimarogonas; James D. Biggs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioning and control; Transition system; Geometric control; Barrier functions; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the development and integration of cyber-physical and safety-critical systems, control systems are expected to achieve tasks that include logic rules, receptive decision-making, safety constraints, and so forth. For example, in a persistent surveillance application, an unmanned aerial vehicle might be required to "take photos of areas A and B infinitely often, always avoid unsafe region C, and return to the charging point when the battery level goes low.

  4. 22. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions

    Author : Mohamed Abdalmoaty; Håkan Hjalmarsson; Adrian Wills; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction Error Method; Maximum Likelihood; Data-driven; Learning; Stochastic; Nonlinear; Dynamical Models; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Estimation; Process Disturbance; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. READ MORE

  5. 23. Cosmological Models and Singularities in General Relativity

    Author : Patrik Sandin; Claes Uggla; Alan Coley; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; general relativity; Bianchi cosmology; singularities; dynamical systems; Fuchsian methods; Hamiltonian methods; Theory of relativity; gravitation; Relativitetsteori; gravitation; Physics; Fysik;

    Abstract : This is a thesis on general relativity. It analyzes dynamical properties of Einstein's field equations in cosmology and in the vicinity of spacetime singularities in a number of different situations. READ MORE

  6. 24. Gaussian process models of social change

    Author : Björn Rune Helmer Blomqvist; David J. T. Sumpter; Ranjula Bali Swain; Ian Vernon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gaussian processes; Bayesian statistics; Dynamical systems; Social sciences; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : Social systems produce complex and nonlinear relationships in the indicator variables that describe them. Traditional statistical regression techniques are commonly used in the social sciences to study such systems. READ MORE

  7. 25. Reactive Motion Planning and Control under Constraints

    Author : Albin Dahlin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational geometry; online trajectory generation; navigation; optimization-based control; robotics; dynamical systems;

    Abstract : Modern robots are increasingly being designed to operate in dynamic and unstructured environments shared with humans and other mobile agents. In these scenarios, the robot must react to any online detected changes to provide a correct and safe operation. READ MORE
