On application of Cramer’s rule

Lietuvos Matematikos Rinkinys, 2011
The article analyses a possibility of modification of Cramer’s rule. The modified formulas for the solution of a system of linear equations, with application of which the volume of calculation reduces, are suggested.

An effective and economic estimation of population mean in stratified random sampling using a linear cost function [PDF]

Heliyon
Improvement in the estimation of population mean has been an area of interest in sampling theory. So many estimators have been suggested for elevated estimation of the population mean in stratified random sampling, but there is still a gap for more ...

Differential Thermal Inactivation Enables Simultaneous Quantitation of Ricin and Abrin [PDF]

Toxins
Ricin and abrin are highly lethal Type II ribosome-inactivating proteins. They depurinate the same site of the 28S rRNA to inhibit protein synthesis. Consequently, standard molecular-level activity assays used to detect the toxic activity of ricin or ...

Generating functions for a lattice path model introduced by Deutsch

Special Matrices, 2021
The lattice path model suggested by E. Deutsch is derived from ordinary Dyck paths, but with additional down-steps of size −3, −5, −7, . . . . For such paths, we find the generating functions of them, according to length, ending at level i, both, when ...

Characterizations of the Generalized MPCEP Inverse of Rectangular Matrices

Journal of Applied Mathematics, 2023
In this paper, we introduce a new generalized inverse, called the G-MPCEP inverse of a complex matrix. We investigate some characterizations, representations, and properties of this new inverse.
