Comparative performance analysis of some accelerated and hybrid accelerated gradient models
We analyze a performance profile of several accelerated and hybrid accelerated methods. All comparative methods are at least linearly convergent and have satisfied numerical characteristics regarding tested metrics: number ... -
A comparative study of two different finite difference methods for solving advection–diffusion reaction equation for modeling exponential traveling wave in heat and mass transfer processes
(Springer, 2021-10-26)An unconditionally-positive finite difference (UPFD) and the standard explicit finite difference schemes are compared to the analytical solution of the advection–diffusion reaction equation which describes the exponential ... -
Comparison of adaptive algorithms for free space optical transmission in Malaga atmospheric turbulence channel with pointing errors
(2019)In this study, the authors investigate average capacity of free space optics communication over Málaga atmospheric turbulence channel with pointing errors and path loss, for intensity modulated/direct detection (IM/DD) and ... -
Complex homogeneous differential equation of first and second order through iterations
The theory of complex differential equations represents an important mathematical discipline both from the theoretical point of view and from numerous applications. Its development was equally encouraged by mathematicians, ... -
Computing support for testing equal values of the figurative numbers in the Pascal triangle
(Proceedings of the 7th Technium Conference 2020, 2020-09-15)In this paper we deal with a method for the determination of numbers in a Pascal triangle that are simultaneously triangular, tetrahedral and pentaedroidni. The collected results, obtained by mathematical analysis, were ... -
