On the one method of a third-degree bezier type spline curve construction

Autor: Stelia, O., Potapenko, L., Sirenko, I.

A method is proposed for constructing a spline curve of the Bezier type, which is continuous along with its first derivative by a piecewise polynomial function. Conditions for its existence and uniqueness are given. The constructed curve lies inside

Ein mathematisches Modell des Pilmycelwachstums in submerser Batchkultur

Autor: Sirenko, I. P., Solomko, E. F., Kosman, E. G.

A mathematical model is suggested for the growth of fungal mycelium in the homogeneous periodical culture. Based on the model equations, the economic coefficient is calculated which in the given case is not a constant. Besides, the maximal value of t
