The Geometry of the Hilton Splitting

چکیده

One of the important theorems in homotopy theory is the Hilton Splitting Theorem which states: there is an isomorphismH = ⊕γ∈ΓHγ from them-th homotopy group of the wedge of a number of spheres to the direct sum of the m-th homotopy groups of some spheres, see [Hi]. In this paper we will construct geometrically all Hilton homomorphisms Hγ and prove a family of sharper symmetry relations between linking coefficients which desuspend and generalize the relations of Kervaire [Ke], Haefliger and Steer [Ha,St].

Three-Phase Modeling of Dynamic Kill in Gas-Condensate Well Using Advection Upstream Splitting Method Hybrid Scheme

Understanding and modeling of three-phase transient flow in gas-condensate wells play a vital role in designing and optimizing dynamic kill procedure of each well that needs to capture the discontinuities in density, geometry, and velocity of phases but also the effect of temperature on such parameters. In this study, two-phase Advection-Upstream-Splitting-Method (AUSMV) hybrid scheme is extend...

Investigating Different Methods of Closed Shell Pistachios Splitting and Effects of Freezing Prior to Drying on Shell Splitting Percentage

In this study, different methods for shell splitting and the effect of freezing prior to drying on shell splitting percentage of pistachio were investigated. A completely randomized design was used to investigate the effects of different freezing temperatures (0, -6, -12 and -18°C), different drying temperatures (80, 90 and 100°C) and different cultivars (Akbari and Kalehghouchi) on shell split...

نگاشت همدیس در طرح‌های انگشتی سافمن- تیلور

 We studied the growth of viscous fingers as a Laplacian growth by conformal mapping. Viscous fingers grow due to Saffman-Taylor instability in the interface between two fluids, when a less viscous fluid pushes a more viscous fluid. As there was an interest in the rectangular Hele-Shaw cell, we solved the Laplacian equation with appropriate boundary conditions by means of conformal mapping tech...

Assessment of Effect Technical Directional Bremsstrahlung Splitting (DBS) on Spectra and Parameters of Simulation with Monte carlo Method BEAMnrc Code (Study Monte Carlo)

Introduction: Previous studies have shown that a Monte Carlo method for the transportations photon beam in medical linear accelerator is a good way. Strip of simulation can be used to measure the dose distribution in phantoms and patients' body. EGSnrc Code is the only code written for use in the field of radiation therapy that has many subset codes that BEAMnrc code is an impo...

The numerical simulation of compressible flow in a Shubin nozzle using schemes of Bean-Warming and flux vector splitting

Over the last ten years, robustness of schemes has raised an increasing interest among the CFD community. The objective of this article is to solve the quasi-one-dimensional compressible flow inside a “Shubin nozzle” and to investigate Bean-Warming and flux vector splitting methods for numerical solution of compressible flows. Two different conditions have been considered: first, there is a sup...
