Norm Estimates for Norm-Attainable Operators
(JOOUST, 2019)Hilbert space operators have been studied by several mathematicians over decades and various interesting results have been obtained. There are several classes of Hilbert space operators, for example, normal, ... -
Norms and Numerical Radii Inequalities of Derivations Induced by Orthogonal Projections
(JOOUST, 2022)Properties of derivations that have been studied by different mathematicians include norms, numerical ranges, spectra and positivity. However, norms and numerical radii inequalities of derivations induced by orthogonal ... -
On Compact Operators whose Norms are Eigenvalues
(JOOUST, 2019)The class of compact operators is fundamental in operato_Lllle~+Y.• Char-acterization of compact operators acting on different sp~ces has been fas-cinating to many Mathernaticians., Many properties such as bounded¬ness, ... -
On Complete Positively and Boundedness of Operators on Non- Unital C*- Algebras.
(JOOUST, 2017)Properties of completely positive and completely bounded operators are fundamental in understanding the applications of operator theory in other fields like quantum mechanics. Up to date the question as to whether com• ... -
On Continuity and Separability in Bitopological Spaces
(JOOUST, 2023)Many studies have been conducted on properties of bitopological spaces and aspects of continuity over a long period of time and different results have been obtained so far. However, pointwise characterization of various ... -
On Semi-Continuous Functions and Convex Optimization in Lp-Spaces
(JOOUST, 2023)The study of semi-continuity and optimization has garnered significant attention from mathematicians for a prolonged period. While characterization of semi-continuity has been conducted in topological spaces and Hilbert ... -
Opportunities of Recreational Ecotourism in Water Resources within Beach Environments of Lake Victoria.
(JOOUST, 2017)Ecotourism, one of the world's biggest revenue generating industries world over, utilizes natural water resources as recreational destinations in most economies around the world. However, developing nations, ... -
Orthogonality of Finite Rank Generalized Derivations
(JOOUST, 2020)Properties of derivations have been studied by various mathematicians for instance, norm, numerical range, spectrum, positivity among others. Range-kernel orthogonality is also a property for derivations implemented by ... -
Preparation, Characterization, Optimization and Pre-Clinical Evaluation of Selected Anti-Malarial Drugs Encapsulated into Different Nanocarriers
(JOOUST, 2015)Artemisinin and its derivatives have proved to be very effective against malaria parasites although it has the short falls of low solubility, poor bioavailability and short half-lives. Instead of discarding these drugs it ... -
Reconstruction of vegetation index and Phenology lab enhanced vegetation index record: An application of weak solution to stochastic partial differential equations approach
(JOOUST School of Mathematics & Actuarial Sciences, 2016-05)A long-term record of the Earth’s vegetation index record is important in studies of global climate change and feedbacks. Over the last three decades, many satellite based sensor platforms have generated multiple vegetation ... -
Relationship Between Internal Psychological States and Indulgence in Behaviour Problems of Secondary School Students in Kenya.
(2017)Behavioural problems among students are a challenge in most Kenyan schools and the occurrence of behavior problems among students has been reported in Kisii County. Since most of the previous studies have ... -
Rotundity of Norms in Frechet Spaces
(JOOUST, 2019)The notion of rotundity of norms is a very interesting area of research in analysis. The question whether if a norm is Highly Rotund implies it is Midpoint Locally Uniformly Rotund or whether a Uniformly Ro¬tund norm in ... -
Selected teacher variables influencing mathematics achievement among secondary school students in Western Kenya:
(2015)The study investigated selected teacher variables influencing achievement in mathematics among secondary school students in western Kenya. A comparison was made between teachers holding a ... -
Stochastic Modeling of Road Accidents Using Poisson and Negative Binomial as th Error Term Distributions Assuming Polynomial Priors
(JOOUST, 2016)Cloud computing is a technological paradigm that enables computer users to access computing applications and services on a pay-as-you-use model. Over the years, the adoption of cloud computing by cloud service providers ... -
