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.
In this paper we prove new results about data dependence of ( Suantai , CR , (8) ) Iterations when applied to contractive- Like operators in real Banach spaces .
We use these results for finding fixed point of certain operator instead of com
puting.
Where we approximate the operator with a contractive –Like one, for which it is possible to compute the fixed point.
We resolve two examples by using Excel program to explain the results
The importance of this research lies in notifying analytic
geometry principles in Lobachevsky plane which differ from
the famous principles in Euclidean plane .
In this research, length of curves with constant curvature ,
length of a circle and a
n arc length of it opp to a central angle
has been found . Moreover , it has been reached to a formula
to express the distance between two points ; then writing a
line equation passes coordinates principle , a line equation that
doesn`t pass coordinates principle and a circle equation. We
coordinates which have used for that Beltrami
made the formulas simpler.
The aim of this paper is to study the changes of knee movement during walking for
patella femoral pain using flexible electro-goniometry, This is very important for gait research
and stability of knee, the start and end of the gait cycle were deter
mined by foot sensors, A
program was designed for signal processing of the data by Mat lab, Testes were carried out at
Hamish hospital in Damascus, Subjects were divided into two groups: 46 normal subjects and
21 patients. Results showed that the lesion effect on knee movement which the values of knee
flexion are less than normal, In the stance phase it is noted that the knee cancels its first
flexion, and In swing phase it noted that the decrease in knee flexion. It was also noted that
these values were varied between the patient tested.
The objective of this study is to study some of the optimal analytical conditions for the
determination of the Cu2+ ion using potentiometric titration method using the platinum
electrode as a working electrode and the AgCL/Ag as a Reference electro
de.
In this study, the technical conditions were studied (working Electrode type, Reference
Electrode type, Direction of titration, delay time, Proportional band, Speed of stirring)
and the analytical conditions (pH value, time factor, quantity of solid KI added, electrolyte
type and its concentration, detection limit) were studied using oxidation - reduction
reactions as the method of iodide titration which applied successfully electrochemical for
determine the Cu2+ ion.
