Nonlocal active sound control for composite regions

Mathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Solution of two-dimensional parabolic equation with nonlocal integral boundary conditions

Lietuvos matematikos rinkinys, 2011
Two-dimensional parabolic equation with nonlocal integral boundary conditions in a rectangle domain in this paper is solved by  alternating direction method. To find the solutions of this problem we are looking to solve a linear system of equations. This algorithm is realized on particular example and assess the error of solution.

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.
