This paper presents the use of finite Matrices to encrypt messages encoded using ASCII system, dependent on the method (Hill cipher) 1929 by: 1. Using finite Matrices to divide the text into partial Matrices. 2. Depending on encoding ASCII (ASCII Coding). 3. Using the matrices A,X,B have special conditions to make Hill function ( f(X)=(A.X+B)mod(n)) able to encrypt the text P that corresponding in the matrix. This matrix contains partial Matrices to get encryption messages with different keys to make it difficult to break, and save the security of information in the texts. 4. Method can be applied on the computer to give quick and great results.

In this paper, we comparison of some approximate solutions
for the Advection equation. This solutions built on numerical
methods to obtain approximate others, depending on two different
ways; the first is Finite Difference Methods, using Crank-Nic
holson
Method, and Implicit Logarithmic Finite Differences Method, and
second is The Finite Elements Methods, throw modified cubic BSpline
differential quadrature method using types for Basis
functions (MCBDQM), (EMCB-DQM), and (Expo-MCB-DQM).
This study aims to investigate the effect of the alveolar ridge shape in
the distribution of stress at the lower removable partial dentures
supported by implants using a finite element method, with four models
for a half mandible are designed with
a free end saddle using an
ANSYS program and Canine was abutment, where the remaining ridge
is representing the four alveolar ridge shapes (horizontal and distal
descending and concave and distal ascending), two removable partial
dentures were designed for each model one supported by tooth and
fibromucosa and another one supported by tooth and implant, it has been
applied a load of 50 Newton on all models and has been studied stress
equivalent for each model.
Tensile and bending tests modeling have been undertaken for various welded joints
which were different in shape and design. Also, the hot spot stress was calculated at critical
failure areas using the finite elements analysis method. There was a go
od similarity
between experimentally defined critical areas in certain certified literature and those in our
modeling. It appeared that the information listed in the international institute for welding
(IIW) in regards of hot spot stress method gives relatively accurate values for the welded
joints possibility to endure fatigue loading and keep their desired mechanical properties
even those joints that could fail only at the connecting area with the base metal.
This research presents a study of distribution of the

In this work, a modified finite element displacement approach is used to analyze two
and three dimensional Framed Structure. The element is based on second order theory.
