    Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER

  2. 2. eScience Approaches to Model Selection and Assessment Applications in Bioinformatics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Martin Eklund; Uppsala universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; high-throughout biology; eScience; model selection; model assessment; TECHNOLOGY Bioengineering Bioinformatics; TEKNIKVETENSKAP Bioteknik Bioinformatik;

    Sammanfattning : High-throughput experimental methods, such as DNA and protein microarrays, have become ubiquitous and indispensable tools in biology and biomedicine, and the number of high-throughput technologies is constantly increasing. They provide the power to measure thousands of properties of a biological system in a single experiment and have the potential to revolutionize our understanding of biology and medicine. LÄS MER

  3. 3. Covariate Model Building in Nonlinear Mixed Effects Models

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jakob Ribbing; Uppsala universitet.; [2007]

    Sammanfattning : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. LÄS MER

  4. 4. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sara K. Olofsson; Uppsala universitet.; [2006]
    Nyckelord :Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

    Sammanfattning : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. LÄS MER

  5. 5. Model on Demand : Algorithms, Analysis and Applications

    Detta är en avhandling från Linköping : Linöping University

    Författare :Anders Stenman; Linköpings universitet.; Linköpings universitet.; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : System identification deals with the problem of estimating models of dynamical systems from observed data. In this thesis, we focus on the identification of nonlinear models, and, in particular, on the situation that occurs when a very large amount of data is available. LÄS MER
