Fisher’s Fiducial Inference for the parameters of a totality uniformly distributed on [α, β] is discussed. The corresponding fiducial distributions are derived. The maximum fiducial estimators, fiducial median estimators and fiducial expect estimators of α and β are got. The problems about the fiducial interval, fiducial region and hypothesis testing are discussed. An example which showed that Neyman-Pearson’s confidence interval has some place to be improved is illustrated. An idea about deriving fiducial distribution is proposed.
tapered angles of an artery significantly influence the local hemodynamics.
However, as gravity is considered, little is known about the effect of tapered
angles on the hemodynamics. In this study, we explored whether the effect of
tapered angles on the distribution of blood flow pressure (DBFP) differed with
gravity considered or not. Numerical simulations of the DBFP in a single vessel
were performed based on such tapered angles as 0°, 0.5° and 1°. In the model
used for simulation, gravity was introduced as a body force. We obtained the
following simulations: i) The larger the tapered angles were, the better distributed
the blood flow pressure; ii) The tapered effect was an important factor leading
to nonlinearity in blood flow pressure; iii) Gravity affected DBFP coupling
with the tapered angles, yet independently influenced the dimension of the DBFP.
At the same time, the effective intensity of gravity decreased with the increase
of tapered angles.
