| Abstract [eng] |
Master thesis solved differential equation of diffusion of new techniques methods. Having analyzed the standard variable diffusion coefficient parabolic equation solution methods suggested in this work we solve these equations using the so-called "bridge" function. Tried two types of "bridge" functions: tangent hyperbolic and trigonometric. Differential equation, the solution we were looking for a "bridge" function and the amount of products of powers of polynomials: trigonometry "bridge" function and hyperbolic tangent of a "bridge" function. We have received computer-based solutions and the solutions found at the margins. A comparison of hyperbolic tangent trigonometric "bridge" function of the error standard deviations have received, the more accurate the hyperbolic tangent of a "bridge" function approach. |
