  3. 2. Lower Extremity Function in Arthritis

    Författare :Ann Bremander; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; Skelett; rheumatology locomotion; muscle system; Skeleton; Knee injury; Arthritis; Reliability; Self-registered physical function; Validity; Observed physical function; Physical medicine; Rehabilitering medicinsk och social ; kinesitherapy; revalidation; rehabilitation;

    Sammanfattning : The aim of this thesis was to develop and apply self-registered and observed measures of physical function in people with arthritis in the lower extremity. In Paper I, 181 subjects from the Swedish Knee Arthroplasty Register who were satisfied with their primary knee arthroplasty were studied. LÄS MER

  4. 3. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Författare :Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Sammanfattning : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.

  5. 4. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

    Författare :Gustaf Hendeby; Fredrik Gustafsson; Niclas Bergman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; Automatic control; Reglerteknik;

    Sammanfattning : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. LÄS MER

  7. 5. Learning Sequential Decision Rules in Control Design: Regret-Optimal and Risk-Coherent Methods

    Författare :Matias I. Müller; Cristian R. Rojas; Håkan Hjalmarsson; Tom Oomen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Engineering sciences deal with the problem of optimal design in the face of uncertainty. In particular, control engineering is concerned about designing policies/laws/algorithms that sequentially take decisions given unreliable data. This thesis addresses two particular instances of optimal sequential decision making for two different problems. LÄS MER
