TY - JOUR TI - Numerical solution of initial-boundary value problems with integral conditional for third-order-differential equations AU - Karakas Mehmet JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 211 EP - 219 PT - Article AB - Water quality differential equation based on the theoretical bases of change is a multiparameter mathematical. When we compared with water quality measurement valves, it is determined that the concentration valve rate is not balanced and the two parameters, change solution is current and unique. When change conditions only one solution will not be the determinant of Jacobi matrix linear connection. Therefore, this research will help the availability in theory and uniqueness of the solution to the problem of water quality parameters. This method provides compatibility between real data to issue water quality parameter change obtained using the equation of the estimated value of the third row and differantive. The numerical solution of start-border value problem which is integral conditioned for third-order-differential balance and the analytical property of problem is analyzed. The application phases are shown, contribution is given theorem, some remarks about the results produced and made in the light of their theorems.
