This short paper continues to discuss randomness of the Euler’s number e digits in decimal expansion. To analyze such randomness statistically, we exploit fixed-effects and random-effects Poisson panel-data models. The results of the regression models reveal the presence of some...

In this paper we introduce a weighted retro Banach frame for a discrete signal space. Necessary and sufficient condition for the existence of weighted retro Banach frames is obtained. Construction of weighted retro Banach frames from bounded linear operator is discussed. A Paley-...

In this paper, an algorithm for solving high-order non-singular Sturm-Liouville eigenvalue problems is proposed. A modified form of Adomian decomposition method is implemented to provide a semianalytical solution in the form of a rapidly convergent series. Convergent analysis and...

The article is dedicated to the creation of the fragment of table algebras theory constructed on the basis of classical relational Codd’s algebras. The distinctive peculiarity of the adapted technique is the use of set-theoretic properties of some constructions (full image of the...

The phenomenon of Fluid flow separation is associated with a number of Fluid Flow Problems faced in real life situation nowadays. To understand these flow problems even under the assumption of the incompressible viscous flow is quiet a difficult task. The complexity lies on the w...

In this work we present a mathematical model for tumour growth based on the biology of the cell cycle. Our model reproduces the dynamics of three different tumour cell populations: Quiescent cells, cells during the inter phase and mitotic cells. Here, we investigate the stability...

We study an associative algebra A over an arbitrary field, that is a sum of two subalgebras B and C (i.e. A = B+C). We prove that if B has a nil ideal of bounded index, and that C has a commutative ideal, both of finite codimension in B and C, respectively, then for some nil PI...

In this work, we present a technique for the analytical solution of systems of sti ordinary dierential equations (SODEs) using the power series method (PSM). Three SODEs systems are solved to show that PSM can nd analytical solutions of SODEs systems in convergent series form. Ad...
