STUDY OF THE FINITE FINAL POINT OPTIMAL CONTROL PROBLEM

The paper presents a simple method for obtaining the analytical formula and the graphical representation of the trajectory and optimal control for a class of control problems, with fixed or free final state form.

THE EQUIVALENCE BETWEEN SOME DIFFERENTIAL EQUATIONS

The classical method for solving Riccati equations uses a change which leads to a first order linear equation. We give here a new method of the variation of constants.

STUDY OF THE OPTICAL PROPERTIES OF POLAR BEAR HAIR IN THE INFRARED RANGE AND THEIR MICROSCOPIC STRUCTURES FOR PASSIVE CONTROL OF TEMPERATURE

If you are looking for the biggest land mammals, you will find them in northern Alaska, northern coast of Russia, Canada, Greenland and Norway. Polar bear (Ursus maritimus) is immediately recognizable by the white fur; i...

ABOUT SOME FUNCTIONAL INTEGRAL EQUATION IN SPACE WITH PERTURBATED METRIC

A NEW GEOMETRIC INEQUALITY AND ITS APPLICATIONS

In this paper, we establish a ternary quadratic geometric inequality involving a triangle and a point by using the polar moment of the inertia inequality of M.S. Klamkin. We also give new result some applications, and pr...
