ON THE CYCLE INDICES OF FROBENIOUS GROUPS
(2010)There are several very useful formulas, which give the cycle indices of the binary operation of the sum, product, composition and power group of M and H in terms of cycle indices of M and H. One very useful binary operation ... -
CdxZn1-xS/Pbs Thin film solar cell
(Global Advanced Research Journal of Engineering, Technology and Innovation, 2014)In this work, n-type CdxZn1-xS and p-type Pbs layers were optimized through chemical solution technique for solar cells. CdxZn1-xS was grown at 82°C while Pbs layers were grown at room temperature utilizing aqueous conditions. ... -
The application of logistic regression in modeling of survival chances of HIV-positive patients under highly active antiretroviral therapy (HAART): A Case of Nyakach District, Kenya
(Basic Research Journal, 2014)In Kenya the number of persons requiring antiretroviral Therapy (ART) in 2012 was over 90,000 while globally more than 1.4 million were under ART in the year 2012. Though ART treatment has decreased mortality of HIV associated ... -
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 ... -
PfEMP1 DBLα Sequence Tags in Genomic DNA of P. falc iparum Field Isolates from Two Malaria Endemic Sites in Ke nya
(Journal of Natural Sciences Research, 2015)Malaria caused by Plasmodium falciparum remains a major cause of childhood morbidity and mortality in sub-Saharan Africa. PfEMP1 protein, coded for by a family of about sixty variant var genes, is a parasite protein found ... -
Modeling Damping for a Loaded Spring in an Acoustic Liquid Media
(Engineering International, 2016)Free vibrating motion can take place in an acoustic media. This motion can be steady hence have constant periodic variations or unsteady and thus experience light damping or heavy damping. We give a modeled analysis of ... -
Alternative Multipole Expansion of the Electron Correlati on Term
(arXiv.org, 2017)An alternative multipole expansion of the correlation term is derived. Modified spherical Bessel type functions which simplify as a summation of multiple ord ers of basic trigonometric functions are generated from this ... -
Classifying fuzzy subgroups of the abelian group Zp1× Zp2×···× Zpn for distinct primes p1, p2,···, pn
(2017)In this paper, we classify the fuzzy subgroups of the group G= Zp1× Zp2×···× Zpn where p1, p2,···, pn are distinct primes and n∈ Z+. We develop an algorithm for counting the distinct fuzzy subgroups of the group G using ... -
A NUMERICAL STUDY OF TURBULENT NATURAL CONVECTION IN A RECTANGULAR ENCLOSURE USING A TWO-EQUATION TURBULENCE MODEL
(Asian Journal of Mathematics and Computer Research, 2017)Turbulent natural convection has been studied both numerically and theoretically. This work numerically studies turbulent natural convection in a rectangular enclosure with varying aspect ratios of 0.5, 1 and 2. The vertical ... -
