    Sammanfattning : Inverse problems arise in any scientific endeavor. Indeed, it is seldom the case that our senses or basic instruments, i.e., the data, provide the answer we seek. LÄS MER

  3. 2. Observability and identifiability of nonlinear systems with applications in biology

    Författare :Milena Anguelova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Observability; identifiability; nonlinear systems; time delay; delay systems; state elimination; metabolism; conservation laws; signalling pathways.; signalling pathways.;

    Sammanfattning : This thesis concerns the properties of observability and identifiability of nonlinear systems. It consists of two parts, the first dealing with systems of ordinary differential equations and the second with delay-differential equations with discrete time delays. LÄS MER

  4. 3. Model-based and matched-filterbank signal analysis

    Författare :Andreas Jakobsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-parametric spectral estimation; efficient implementations; array processing; parameter estimation; identifiability; subspace fitting; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

    Sammanfattning : The dissertation deals with model-based and matched-filterbank signal analysis. The matched-filterbank (MAFI) spectral estimation approach is introduced, and it is shown that both the amplitude spectrum Capon (ASC) and the amplitude and phase estimation (APES) spectral estimators can be expressed as MAFI spectral estimators.

  5. 4. Towards Individualized Drug Dosage : General Methods and Case Studies

    Författare :Martin Fransson; Peter Fritzson; Lena Friberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drug dosage; population pharmacokinetics; biochemical modelling; identifiability; parameter estimation; Bioinformatics; Bioinformatik;

    Sammanfattning : Progress in individualized drug treatment is of increasing importance, promising to avoid much human suffering and reducing medical treatment costs for society. The strategy is to maximize the therapeutic effects and minimize the negative side effects of a drug on individual or group basis. LÄS MER

  7. 5. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data

    Författare :Andreas Linderholt; Thomas Abrahamsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modal tests; test design; identifiability; Fisher information; optimization; data informativeness; model updating; Maskinteknik;

    Sammanfattning : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibrations. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be modified. LÄS MER
