Relative Efficiency of Sum Constructed Automorphic Symmetric Balanced Incomplete Block Designs
(ResearchGate, 2020)Several construction methods have been introduced to build the elements of BIBDs’ for specific parameters, with different techniques suggested for testing their existence, still no general technique to determine the ... -
Semi-Parametric Modeling of Churn Confounding Competing Risks Using Time-Dependent Covariates Among Mobile Phone Subscribers in Kenya
(Istanbul University, 2023-06-01)Mobile phone service providers are currently experiencing high churn rates. As a result, service providers are trying to develop ways to predict churn rates and uncover why subscribers’ churn occurs. However, the task of ... -

(International Journal of Scientific Research in Mathematical and Statistical Sciences, 2020)- In this study Sum construction method of automorphic symmetric balanced incomplete block designs has been presented in details. Efficiency of a test design used in the Sum construction of automorphic symmetric ... -
Symmetry-dependent analytical all-electron potential for helium atom
(Elsevier, 2022-09-01)Electron–electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron systems are the simplest many-body systems in nature. The Schrödinger ... -
The upper triangular algebra loop of degree 4
(Charles University in Prague, Faculty of Mathematics and Physics, 2014)A natural loop structure is defined on the set $U_4$ of unimodular upper-triangular matrices over a given field. Inner mappings of the loop are computed. It is shown that the loop is non-associative and nilpotent, of class ...
