    Författare :Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Parameter Estimation; Continuous-time Stochastic Systems; Networked Control Systems; Errors-in-variables Systems; Wireless Channel Modeling; Closed-loop Identification; Physics; Fysik;

    Sammanfattning : The scope of the thesis is to estimate the parameters of continuous-time models used within control and communication from sampled data with high accuracy and in a computationally efficient way.In the thesis, continuous-time models of systems controlled in a networked environment, errors-in-variables systems, stochastic closed-loop systems, and wireless channels are considered.

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

    Författare :Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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. 3. "Jag lärde mig väl det vanliga!" : Fem elevers erfarande av skrivande som aktivitet för lärande

    Författare :Magnus Jansson; Boel Englund; Anna Vogel; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Learning; writing; experiencing; phenomenography; sociocultural perspective; pedagogik; Education;

    Sammanfattning : This study is about students’ work with writing as an activity for learning in year 4, 5 and 6 in compulsory school. The methodology used is inspired by phenomenography and the overall frame of analysis is sociocultural. LÄS MER

  4. 4. On performance analysis of subspace methods in system identification and sensor array processing

    Författare :Magnus Jansson; Bo Wahlberg; Mats Molander; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subspace methods; system identification; state-space models; linear regression; sensor array processing; performance analysis; EM algorithm; minimum redundancy array;

    Sammanfattning : This thesis addresses the issue of performance analysis of subspace-based parameter estimation methods in two different applications, namely system identification and sensor array processing.  The objective is to study the quality of the estimated models as the amount of data increases, and to suggest improvements and give user guidelines.
