  1. 16. Some problems of modeling and parameter estimation in continous-time for control and communication

    Författare :Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Continuous-time modeling; identification; estimation; closed-loop systems; networked control systems; wireless communication; stochastic differential equations; Physics; Fysik;

    Sammanfattning : Stochastic system identification is of great interest in the areas of control and communication. In stochastic system identification, a model of a dynamic system is determined based on given inputs and received outputs from the system, where stochastic uncertainties are also involved. LÄS MER

  3. 17. Advanced NMR techniques for structural elucidation in medicinal chemistry

    Författare :Hermina Wieske; Máté Erdélyi; Mikael Akke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The nuclear Overhauser effect (NOE) is an NMR phenomenon that can reveal spatial proximity between two atoms. It has found applications in organic chemistry and structural biology including natural product chemistry, organic synthesis, medicinal chemistry, macromolecular structure elucidation and protein-ligand interactions.

  4. 18. On identification of continuous-time systems and irregular sampling

    Författare :Erik K. Larsson; Torsten Söderström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Sammanfattning : The problem of identifying continuous-time systems is of fundamental interest in various areas, such as, astrophysics, economics, control and signal processing. Over the years there has been an extensive research going on in this field, which has resulted in numerous publications. LÄS MER

  5. 19. När fysik blir lärområde i förskolan

    Författare :Jonna Larsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergent science; physics; children; learning; preschool; begynnande naturvetenskap; fysik; barn; lärande; förskola;

    Sammanfattning : This dissertation includes four separate empirical studies, and is directed towards what happens when physics becomes a learning area in preschool. It is about children and preschool teachers exploring and working with physical phenomena such as friction, sound, floating and sinking. LÄS MER

  7. 20. Approximate Solution Methods to Optimal Control Problems via Dynamic Programming Models

    Författare :Yuchao Li; Jonas Mårtensson; Karl H. Johansson; Pontus Giselsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal control; dynamic programming; model predictive control; Electrical Engineering; Elektro- och systemteknik; Optimization and Systems Theory; Optimeringslära och systemteori;

    Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data, this thesis introduces some suboptimal schemes via abstract dynamic programming models.
