parametric investigation of diesel fuel-air capillary pressure–saturation functions
to examine hydraulics of lnapls in soil, the retention curves of diesel fuel and water were both determined by hanging column method. the soil retention parameters were obtained based on van genuchten, brooks-corey and campbell’s models. in addition, the soil hydraulic conductivity for both fluids were predicted based on mualem- brooks-corey, burdine- brooks-corey, mualem-van genuchten and camp...
متن کاملEstimation of Genetic and Phenotypic Covariance Functions for Longitudinal Data
Covariance functions are the ‘infinite-dimensional’ equivalents to covariance matrices for longitudinal data, i.e. many, ‘repeated’ records per individual taken over a period of time. Their properties are reviewed and illustrated with a numerical example. Restricted Maximum Likelihood estimation of genetic and phenotypic covariance functions fitting an animal model is described.
متن کاملlongitudinal impedance tomography for blood pressure characterization of valve deformation
aorta is formed in a dynamic environment which gives rise to imbalances between many forces that tend to extend the diameter and length. furthermore, internal forces tend to resist this extension. impedance tomography can show this imbalance to stimulate the stenosis of aortic valve, growth of the elastic, collagen and to effectively reduce the stresses in the underlying tissue. in blood flow, ...
متن کاملA longitudinal study of blood pressure.
a single group, and the major part of our knowledge has been derived from retrospective analysis or cross-seetional studies of presumably normal populations. These limited observations have led to conflicting interpretations concerning the nature of hypertension and the importance of various factors in its pathogenesis. Pickering has challenged the classical concept that essential hypertension ...
