  3. 3. Genetic Heteroscedasticity for Domestic Animal Traits

    University dissertation from Uppsala : Sveriges Lantbruksuniversitet

    Author : Majbritt Felleki; Högskolan Dalarna.; [2014]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantitative genetics; genetic heteroscedasticity of residuals; genetic heterogeneity of environmental variation; genetic heterogeneity of residual variance; double hierarchical generalized linear models; teat count in pigs; litter size in pigs; milk yield in cows; somatic cell count in cows; Komplexa system - mikrodataanalys;

    Abstract : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. READ MORE

  4. 4. Numerical Solution of Ill-posed Cauchy Problems for Parabolic Equations

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Zohreh Ranjbar; Lars Eldén; Per Christian Hansen; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Ill-posed mathematical problem occur in many interesting scientific and engineering applications. The solution of such a problem, if it exists, may not depend continuously on the observed data. For computing a stable approximate solution it is necessary to apply a regularization method.

  5. 5. Eigenvalue analysis and convergence acceleration techniques for summation-by-parts approximations

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Andrea Alessandro Ruggiu; Linköpings universitet.; Linköpings universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Many physical phenomena can be described mathematically by means of partial differential equations. These mathematical formulations are said to be well-posed if a unique solution, bounded by the given data, exists. READ MORE
