Stochastic differential equations are one of the most useful areas of the theory of stochastic processes and its applications in mathematics.Some nonlinear (Itô) dynamic stochastic control system driven by
Brownian motion 2 based on dynamic observer have been considered.Output feedback (observer – based) robust and optimal control law which guarantees global (local) asymptotic stable in probability for the

The main objectives of this thesis, is oriented toward function approximation using special type of spline functions, which is called the “Gspline “including the details of the subject. The second objective consider the 1st  order ordinary differential equations of the form: .
y'(x)=F(x,y),   x ∈[a,b]

              In   this   work,   we   studied    the   ``Path-Following  Algorithm``,  which  is  one  of  the  family  algorithms, called ``Interior-Point   Algorithms``. We   are   discussed   two   modifications,    the   first
