the main design objective of axial compressor is the efficiency increasing, pressure ratio and weight loss. these three parameters are used as an objective function and they are computed according to adopted design procedures. in this paper, a design method is presented that named quasi-three-dimensional. physical flow conditions are applied to design by some constraints to avoid irrational res...

A method of interpreting radial distribution functions (RDF) of amorphous metals is proposed in which the role of the local atomic structure is emphasized. It is found that the width and height of the peaks of the RDF are related to the second moment of the atomic-level hydrostatic stress distribution ⟨p2⟩. The results of this analysis are then used to explain the details of the changes that oc...

An exact reduced limiting expression for the generalized radial distribution function D, (r) is derived and compared with quantum distributions for various degrees of excitation. It represents the quantum result at large quantum numbers significantly better than a prior empirical representation of the universal reduced distribution and gives a somewhat larger electronic partition function for t...

An analytic expression is derived for the distribution G(~ R) of the end-to-end distance ~ R of semiflexible polymers in external potentials to elucidate the effect of confinement on the mechanical and statistical properties of biomolecules. For parabolic confinement the result is exact whereas for realistic potentials a self-consistent ansatz is developed, so that G(~ R) is given explicitly ev...

We develop a technique, based on the galaxy distribution function, to synthesize the observed distribution of galaxies. It populates space with a Poisson distribution of cluster centers and places particles around each center according to a speciic prescription. We specify each cluster, assumed to be spherical, by three quantities: the number of particles in the cluster, its radius, and its rad...

Abstract. In order to describe large transverse momentum (pT ) distributions observed in high energy nucleus-nucleus collisions, a stochastic model in the three dimensional rapidity space is introduced. The fundamental solution of the radial symmetric diffusion equation is Gaussianlike in radial rapidity. We can also derive a pT or radial rapidity distribution function, where a distribution of ...

Background: The dose rate distribution delivered by a low dose rate 137Cs pellet source, a spherical source used within the source trains of the Selectron gynecological brachytherapy system, was investigated using the MCNP4C Monte Carlo code. Materials and Methods: The calculations were performed in both water and Plexiglas and the absolute dose rate distribution for a single pellet s...
