In this research, we estimate the survival function by using three
nonparametric estimation methods and is to the method of Kaplan and
Meier, the method Gaussian Kernel and method Weibull Kernel.
Depending on the method of simulation and a complet
e real data from
reality. Where we proposed a new method to estimate the survival
function is to use Weibull Kernel and choose a new value to the optimal
bandwidth, which have an important role in the estimation process.
In ١٩٦٢ R.P.Dilworth introduced the concept of a Noether lattice as an
abstraction of the concept of the lattice of ideals of a Noetherian ring. He
showed that many of the important theorems of classical ideal theory held in
them.
The purpose of
this paper is to introduce and study the concept of
idempotent elements for the multiplicative lattices , since they play very
idempotent role for studying the multiplicative lattices and some rings.
The research was conducted on 25male lambs of Awassi
sheep to compare the effect of using different levels of whole
cotton seeds(WCS). The experiment extended for 70 days,
experimental units were rested, then left for an adaptation period of
10 days, during the adaptation period, the animals were housed in
one pen, in the end of the adaptation period, the lambs were
individually weighed, then divided according to live weight into six
equal groups of an average weights (24-25) kg each.
In this work, we have been found explicit exact soliton wave solutions for Zeldovich
equation with time-dependent coefficients, by using the tanh function method with
nonlinear wave transform, in general case. The results obtained shows that these
exact
solutions are affected the nonlinear nature of the wave variable, it is also shown that this
method is effective and appropriate for solving this kind of nonlinear PDEs, which are
models of many applied problems in physics, chemistry and population evolution.
