Analysis and prediction of battery operating state in Kenyan solar home systems
(JOOUST, 6/24/2015)
Solar power is a valuable source of electrical energy for users in the developing countries, yet many solar home systems are working at indeterminate conditions, much to the dissatisfaction of the users. Lead acid batteries ...
On norm preserving conditions for local automorphisms of commutative banach algebras
(JOOUST, 6/24/2015)
The history of commutative algebra first appeared in 1890 by David Hilbert which was then followed by Banach spaces in 1924 since localization reduces many problems of geometric special case into commutative algebra problems ...
Norms of derivation associated with idempotents and unitary operators
(6/24/2015)
The study of operators has continued to attract the attention of many researchers. Of special interest are the calculations of norms of these operators. Johnson Stampfli wrote a paper on the norms of derivation on algebra ...
On shift of mindset: the importance of change of mindset in helping students get better at getting better in mathematics
(JOOUST, 6/24/2015)
That mathematics is important in enhancing creativity, innovativeness and technological development is undisputable. Kenya like any other African country is endowed with reach human resource yet lesscompetitive ...
On numerical radius attainability for normal self-adjoint operators
(JOOUST, 6/24/2015)
The numerical range and numerical radius are very useful in studying linear operators acting on Hilbert spaces. The operators include normal, hyponormal, normaloid, transaloid, self-adjoint, subnormal, compact and unitary. ...
Norm estimates for convexoid operators
(JOOUST, 6/24/2015)
Hilbert space operators are important in formulation of principles of quantum mechanics and also in other fields of applied sciences. These operators include normal operators, hyponormal operators, normaloid operators, ...
Certain properties of normaloid operators
(JOOUST, 6/24/2015)
In this paper we establish new conditions for contractivity of normaloid operators. We employ some results for contractivity due to Furuta, Nakomoto, Arandelovic and Dragomir. A particular generalization is also given.
Intra-national Ethnic Diasporas: Popular Culture and Mediated Translocal Spaces in Kenya
(2015)
Diasporas are conventionally perceived in terms of dispersed populations on a transnational scale. However, this paper demonstrates that the international dimensions of diasporas do not discount their potential for ...
Effects of farmers’ demographic and socio-economic characteristics on soil degradation in different physiographic units of Nyakach Sub-county, Kenya
(Net Journal of Agricultural Science, 2015-12)
A number of scholars contend that demographic and socio-economic characteristics influence soil degradation. However, the nature and extent of the relationship varies spatially and temporally. Nyakach Sub-county in Kenya ...
Multilingualism and language use patterns: Students attitude towards Kiswahili in Garissa Town, Kenya
(Research on Humanities and Social Sciences, 2015)
This study investigated language attitudes of secondary school learners of Somali descent toward Kiswahili and their patterns of language use in various domains in a multilingual context as evidenced in Garissa Town. The ...
