  1. 16. Inverse and Forward Approaches for Optimal Control and Estimation in Agent-Based Systems

    Författare :Yibei Li; Xiaoming Hu; Per Enqvist; Bijoy Ghosh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomous systems; inverse optimal control; system identification; nonlinear systems; formation control; differential game; credit scoring.; Autonoma system; invers optimal styrning; system identifiering; olinjära system; formationsstyrning; differentialspel; kreditvärdering.; Optimeringslära och systemteori; Optimization and Systems Theory;

    Sammanfattning : This dissertation is concerned with three topics within the field of optimal control and estimation in dynamical agent-based systems, with potential applications that meet both engineering and societal needs. Firstly, the inverse optimal control problem is studied. LÄS MER

  3. 17. Bifurcations and Exchange of Stability with Density Dependence in a Coinfection Model and an Age-structured Population Model

    Författare :Jonathan Andersson; Vladimir Kozlov; Uno Wennergren; Ezio Venturino; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In nature many pathogens and in particular strains of pathogens with negative effects on species coexists. This is for simplicity often ignored in many epidemiological models. It is however still of interest to get a deeper understanding how this coexistence affects the dynamics of the disease. LÄS MER

  4. 18. Samtal om begreppskartor : en väg till ökad förståelse

    Författare :Anna-Karin Westman; Karl Göran Karlsson; Svante Holm; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellbiologi; elevdiskussioner; begreppskartor; Subject didactics; Ämnesdidaktik; Biology; Biologi;

    Sammanfattning : Denna avhandling belyser hur elevdiskussioner om begreppskartor kan bidra till en ökad förståelse för innebörden av de utvalda biologiska begreppen hos de elever som deltar. Som bakgrund till avhandlingen redovisas forskningsresultat vilka visar ett antal svårigheter elever kan ha inom det cellbiologiska ämnesområdet. LÄS MER

  5. 19. Statistical inference and time-frequency estimation for non-stationary signal classification

    Författare :Rachele Anderson; Statistical Signal Processing Group; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Non-stationary processes; stochastic modeling; inference; spectral analysis; time-frequency analysis; classification; biomedical applications; deep learning;

    Sammanfattning : This thesis focuses on statistical methods for non-stationary signals. The methods considered or developed address problems of stochastic modeling, inference, spectral analysis, time-frequency analysis, and deep learning for classification. LÄS MER

  7. 20. Robust inference of gene regulatory networks : System properties, variable selection, subnetworks, and design of experiments

    Författare :Torbjörn E. M. Nordling; Elling W Jacobsen; Rolf Findeisen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network inference; reverse engineering; variable selection; model selection; feature selection; subset selection; system identification; system theory; network theory; subnetworks; design of experiments; perturbation experiments; gene regulatory networks; biological networks;

    Sammanfattning : In this thesis, inference of biological networks from in vivo data generated by perturbation experiments is considered, i.e. deduction of causal interactions that exist among the observed variables. Knowledge of such regulatory influences is essential in biology. LÄS MER
