  4. 3. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk

    Författare :Ingrid Larsson; Göteborgs universitet; []
    Nyckelord :adults; anthropometry; atherosclerotic morbidity; body composition; body fat; cardiovascular disease; DEXA; dual energy x-ray absorptiometry; fat-free mass; FFM; humans; metabolic syndrome; morbidity; mortality; prediction equations; randomly selected sample; reference data; sagittal trunk diameter; TBK; total body potassium; waist circumference;

    Sammanfattning : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. LÄS MER

  5. 4. Approximations of Integral Equations for WaveScattering

    Författare :Andreas Atle; Björn Engquist; Richard Tsai; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integral equations; Marching on in time; On surface radiation condition; Physical Optics; Numerical analysis; Numerisk analys;

    Sammanfattning : Wave scattering is the phenomenon in which a wave field interacts with physical objects. An incoming wave is scattered at the surface of the object and a scattered wave is produced. Common practical cases are acoustic, electromagnetic and elastic wave scattering. LÄS MER

  7. 5. On Estimation and Prediction in Linear Mixed Models : A new approach to studying equal BLUEs and BLUPs

    Författare :Azadeh Chizarifard; Tatjana von Rosen; Katarzyna Filipiak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Best linear unbiased estimator; Best linear unbiased predictor; Linear zero function; Matrix equations; statistik; Statistics;

    Sammanfattning : Linear mixed models (LMMs) are widely used to analyze repeated, longitudinal, or clustered data in many disciplines, such as biology, medicine, psychology, sociology, economics, etc. One of the essential components of a linear mixed model is its covariance structure, i.e. LÄS MER
