The problem of the possible generalization of the classical differential calculus for functions with interval uncertainty of parameters isconsidered. In this regard, various types of uncertainty of function parameters and possible mathematical approaches ... see more

Survey-comparative navigation systems are used for identification of landmarks that typically in the form of spatial objects the underlying surface. The most obvious method for obtains geometric features of the spatial object is processing its three-dimen... see more

In this paper, we consider the stability problem of delay differential equations in the sense of Hyers-Ulam-Rassias. Recently this problem has been solved for bounded intervals, our result extends and improve the literature by obtaining stability in unbou... see more

Riccati differential equations (RDEs) plays important role in the various fields of defence, physics, engineering, medical science, and mathematics. A new approach to find the numerical solution of a class of RDEs with quadratic nonlinearity is presented ... see more

At analysis of item bayes or called with differential item functioning (DIF) using the Mantel-Haenszel’s Chi–squareprocedure, the students in a group is grouped pursuant to their reached score, in a certain interval. This research is aimed atrevealing the... see more

The article deals with some problems related to calculation of derivatives of interval-specified functions. These problems are relevant in the study of systems with any level of uncertainty (nondeterministic systems). Specifically we will speak about simp... see more

Context. There are developed a number of methods to build models of objects with distributed parameters in the system identification theory. The basis of mathematical models of such objects are the systems of partial differential equations or their differ... see more

We apply a general algebraic operational method to obtain solutions of ordinary differential equations.  The solutions are expressed as series of scaled  Hermite  polynomials.  We present some examples that show that the solutions obta... see more

In this paper an initial value problem for a non-linear system of two singularly perturbed first order differential equations is considered on the interval (0,1].The components of the solution of this system exhibit initial layers at 0. A numerical method... see more
