this study presents a comparative survey of direct methods for solving variational problems. thisproblems can be used to solve various differential equations in physics and chemistry like rateequation for a chemical reaction. there are procedures that any type of a differential equation isconvertible to a variational problem. therefore finding the solution of a differential equation isequivalen...
Background: Today, the lack of financial protection against the health costs is recognized as a major flaw in the health systems. It seems that the first step towards solving this problem is exact identification of household health expenditure`s components which will result in better selection of prevention policies and appropriate procedures to solve the problem. Materials and Methods: This s...
Jarcho-Levin syndrome a very rare anomaly is described for a variety of clinical phenotypes consisting of short-trunk dwarfism associated with rib and vertebral anomalies. The patient is two months old infant with spondylocostal dysostosis and bilateral direct recurrent inguinal hernia. He was successfully operated by a new method and after 36 months follow up he did not have any problem.

the problem of downward continuation of the gravity field from the earth’s surface to the reference ellipsoid arises from the fact that the solution to the boundary value problem for geoid determination without applying stokes formula is sought in terms of the disturbing potential on the ellipsoid but the disturbing gravity observations are only available on the earth’s surface. downward contin...
we consider an approximation scheme using haar wavelets for solving a class of infinite horizon optimal control problems (ocp's) of nonlinear interconnected large-scale dynamic systems. a computational method based on haar wavelets in the time-domain is proposed for solving the optimal control problem. haar wavelets integral operational matrix and direct collocation method are utilized to ...
