  2. 1. Particle Filtering and Optimal Control for Vehicles and Robots

    Author : Karl Berntorp; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; optimal control; automotive systems; out-of-sequence measurement; autonomy; model predictive control; sensor fusion; wheel slip; dynamic optimization;

    Abstract : This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. READ MORE

  4. 2. Modelling Phone-Level Pronunciation in Discourse Context

    Author : Per-Anders Jande; Rolf Carlson; Merle Horne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pronunciation modelling; Pronunciation variation; Discourse-context; Phone-level variation; Central standard Swedish; Spoken language annotation; Data-driven methods; Machine learning; Decision trees; Pronunciation lexicon development; Machine-readable lexicon; Phonology; Discourse; Lexicon; Language technology; Språkteknologi;

    Abstract : Analytic knowledge about the systematic variation in a language has an important place in the description of the language. Such knowledge is interesting e.g. in the language teaching domain, as a background for various types of linguistic studies, and in the development of more dynamic speech technology applications.

  5. 3. On the Efficiency and Accuracy of Simulation Methods for Optimal Power System Operation : Convex Optimization Models for Power System Analysis, Optimal Utilization of VSC-type DC Wind Farm Grids and FACTS Devices

    Author : Mohamadreza Baradar; Mohammad Reza Hesamzadeh; Damien Ernst; KTH; []
    Keywords : Electrical Engineering; Elektro- och systemteknik;

    Abstract : Recently, significant changes in electric power systems such as rapid developmentof smart grid and electricity market and integration of non-dispatchablesources have added more complexity to the Power Flow Scheduling (PFS) andPower Balancing (PB) models. For instance, non-dispatchable sources introducean increasing level of uncertainty in the electricity market and power system operation. READ MORE

  6. 4. On the Dynamics and Statics of Power System Operation : Optimal Utilization of FACTS Devicesand Management of Wind Power Uncertainty

    Author : Amin Nasri; Mehrdad Ghandhari; Zhang Xiao-Ping; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trajectory sensitivity analysis TSA ; transient stability; small signal stability; flexible AC transmission system FACTS devices; critical clearing time CCT ; optimal power flow OPF ; network-constrained ac unit commitment ac-UC ; wind power uncertainty; wind power spillage; stochastic programming; Benders’ decomposition; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Nowadays, power systems are dealing with some new challenges raisedby the major changes that have been taken place since 80’s, e.g., deregu-lation in electricity markets, significant increase of electricity demands andmore recently large-scale integration of renewable energy resources such aswind power.

  7. 5. Reinforcement in Biology : Stochastic models of group formation and network construction

    Author : Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. READ MORE
