    Modeling of heterogeneous catalytic reduction process of aldehydes
    (Lviv Polytechnic Publishing House, 2016) Skoretska, Ivanna; Beznosyk, Yuriy; National Technical University of Ukraine “Kyiv Polytechnic Institute”
    The article considers the mathematical model of the reduction reaction of anisyl aldehyde by the Meerwein-Ponndorf-Verley mechanism. The activity of the zeolite catalyst with the assistance of which the reaction took place has been analyzed and calculated the rate constant of reaction.

    Development of mathematical model of controlled plant using the obtained experimental data
    (Lviv Polytechnic Publishing House, 2016) Fedoryshyn, Roman; Klos, Sviatoslav; Savytskyi, Volodymyr; Lviv Polytechnic National University
    The results of the experimental study of the dynamical and static properties of an electric oven as a controlled plant are presented in the paper. Up-to-date microprocessor instruments were applied during the experiments. Mathematical model of the electric oven was developed on the basis of the experimental data. The adequacy of the model was verified.

    Mathematical modeling of linear integration based on reverse formulas
    (Lviv Polytechnic Publishing House, 2016) Kozych, Anna; Lviv Polytechnic National University
    In the research work the accuracy of calculation of transient processes based on mathematical models generated using two multi-implicit methods, formulas of backdifferentiation and back-integration. Object of study - line 750 kV "Zachidnoukrainsk - Vinnytsia" for which were formed mathematical models based on analytical solution of equations of the transition process, the method of back-differentiation formulas and back-integration method formulas that have been implemented in the software complex MathCad. Research transients when switched on unloaded line system (source EDS) showed significantly higher accuracy of results obtained using the method of back-integration formulas ago, compared with the method of back-differentiation formulas.

    The automation of aerobic wastewater treatment
    (Lviv Polytechnic Publishing House, 2016) Safonyk, Andrii; Targoniy, Ivan; National University of Water and Environmental Engineering
    Based on the mathematical model of the process of biological treatment, the system of automatic process control engineering aerobic wastewater treatment was developed. It provides the permissible concentration of impurities at the outlet of the filter. The results of computer simulation to calculate the duration of oxygen, accumulation and allocation solid substrate were presented.
