  1. 1. Bilinear Regression and Second Order Calibration

    Författare :Marie Linder; Pieter Kroonenberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemometrics; calibration; multivariate; hyphenated methods; matrix data; bilinear model; least squares; singular value decomposition; generalized rank annihilation; trilinear decomposition; parallel factor analysis; principal components regression; partial least squares; prediction; matematisk statistik; Mathematical Statistics;

    Sammanfattning : We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. LÄS MER

  3. 2. Adaptive finite element methods for parameter estimation problems in partial differential equations

    Författare :Tao Feng; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parameter estimation; ¯nite element approximation; adaptive ¯nite element methods; a posteriori error estimates; least squares.; MATHEMATICS; MATEMATIK;

    Sammanfattning : Physical and chemical phenomena are often described by a system of partial di®erential equations. These equations usually involve unknown parameters, which cannot be measured directly but which can be adjusted to make the model predictions match the observed data. LÄS MER

  5. 4. A Theoretical Model for Telemedicine : Social and Value Outcomes in Sub-Saharan Africa

    Författare :Mengistu Kifle Gelan; Lars Asker; Philip F. Musa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Telemedicine e-health; Sub-Saharan Africa; Least developed Countries; Visually based Clinical Applications; Information and Communication Technology ICT Transfer; Partial Least Squares; Culture; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : The Sub-Saharan Africa (SSA) region is faced with limited medical personnel and healthcare services to address the many healthcare problems of the region. Poor health indicators reflect the overall decline in socio-economic development. LÄS MER
