Malkina V. Geometrical modelling of surfaces on the basis of special systems orthonormal polinoms

The dissertation is devoted to questions of const- ruction of geometrical models with the help of the special system of orthonormal polinoms. In work the new method of construction of approximate of surfa- ces as a number (line) Furier series on a special ortho- normal to basis is offered. The offered method allows approximate surfaces with features with observance of criterions of approximation. On the basis of the offered method the new solving a task Dirihle. In work the special computing algorithm allowing lowering a computing error is developed. The results of work have found industrial application in designing system of cooling of automobile engines.
