font style='font-size:12px;'>
2009/5/12
We use the method introduced by Karami & Mohebi (2007), and Karami & Teimoorinia (2007) which enable us to derive the orbital parameters of the spectroscopic binary stars by the nonlinear least square...
SPIRAL SOLITON SOLUTION FOR DISK GALAXIES
Galaxies spiral – Galaxies kinematics and dynamics–Methods analytical
font style='font-size:12px;'>
2009/3/11
In this paper, weakly nonlinear dynamics of spiral galaxies is studied,
using reductive perturbation method. One primarely aims at the derivation
of possible soliton solution for two dimensional geo...
TIME SERIES ANALYSIS OF LONG TERM FULL DISK OBSERVATIONS OF THE Mn I 539.4 nm SOLAR LINE

2009/3/2
The equivalent width and central depth data of Mn 539.4 nm solar
spectral line, observed in the period from 1979 to 1992 at Kitt Peak Observatory, was
analyzed in pursuit for periodic changes. As th...
THE DISK EMISSION IN SINGLE PEAKED LINES FOR 12 AGNs

2009/1/15
The disk emission in the single peaked Broad Emission Lines (BELs)
of Active Galactic Nuclei (AGNs) is di±cult to detect. In order to ¯nd the disk
traces in BELs the line pro¯les were simu...
On power series analytic in the open unit disk with finite doble-logarithmic order
Analytic in a disk maximum term central index jump points
font style='font-size:12px;'>
2010/9/13
By introducing the concept of double-logarithmic order, we deal with intrinsic properties between maximum term and central index for a class of analytic functions with slow growth in the open unit dis...
A 5 C -approximation algorithm for minimum weighted dominating set in unit disk graph
Approximation algorithm Dominating set Weighted unit disk graph

2012/11/30
We study the minimum weight dominating set problem in weighted unit disk graph, and give a polynomial time algorithm with approximation ratio 5 C , improving the previous best result of 6 C in [Yao...
Effects of the Earth’s Curvature on the Dynamics of Isolated Objects. Part I: The Disk
Earth’s Curvature Dynamics of Isolated The Disk
font style='font-size:12px;'>
2008/7/2
A disk over the frictionless surface of the earth shows an interaction between the center of mass and internal motions. At low energies, the former is an “inertial oscillation” superimposed to a unifo...
