On the identification of a taxa collected from Egypt in the species sub- group andersoni: Morphological relationships with related species and molecular analysis of inter- and intra- specific variations ( Acari: Phytoseiidae)
(University of NairobiSchool of Biological and Physical Sciences, 2009)Morphological studies of the diagnostic characters of Amblyseius swirskii Athias-Henriot (original description) and A. enab El Badry (several new collections including the type locality) indicated close affinity between ... -
On the influence of urbanization on the water budget in Nairobi city: A numerical study
(2004)The impact of the growth and development of the City of Nairobi on the water budget is simulated using a high-resolution limited-area numerical model. The water substance fields are modelled with full physics in a control ... -
On the Linear Mixed Effects Regression (lmer) R Function for Nested Animal Breeding Data
(2009)This work highlights aspects of the R lmer function for a case where the dataset is nested, highly unbalanced, involves mixed effects and repeated measurements. The lmer function is part of the lme4 package of the statistical ... -
On the lmer function for nested animal breeding data

On the magnetic memory phenomenon in rocks and its bearing on palaeomagnetic measurements
(University of Nairobi, 1968)The results of recent extensive studies on the low field hysteresis in basalts from India and East Africa and the memory phenomenon observed in some of the rocks have been found to have a direct bearing on the various ... -
On the Minimal Entropy Martingale Measure and Multinomial Lattices with Cumulants
(2012)In this article, we describe with relevant examples based on empirical data how to use the minimal entropy martingale measure (MEMM) to price European and American Options in multinomial lattices which take into account ... -
On the normality of the products of n-power Quasinormal operators
(Pushpa Publishing House, Allahabad, INDIA,School of Mathematics, University of Nairobi,, 2012)Given any two normal operators A and B on a Hilbert space H, it is known that AB is not normal in general. However, if A and B commute, then AB is also normal. In this account, we investigate some conditions under which ... -
On the operator equation AB + BA* = A*B+BA = I, Proceedings of the First African Symposium in Pure and Applied Mathematics and Mathematics Education
(University of Nairobicollege of biological and physical science, 1981) -
On The Ordered Sets In n-Dimensional Real inner Product Spaces
(University of NairobiDepartment of Mathematics, Faculty of Science and Arts, Afyon Kocatepe University, Turkey., 2000)Let X be a real inner product space of dimension ¸ 2. In [2], W. Benz proved the following theorem for x; y 2 X with x < y: "The Lorentz-Minkowski distance between x and y is zero (i.e., l (x; y) = 0) if and only if [x; ... -
On the performance of three-stage group screening experiments On the performance of three-stage group screening experiments
(School of Mathematics, 1987)This paper examines the performance of three-stage group screening in terms of the mean number of tests needed; and the proportion of active factors correctly detected by the screening plan, A linear cost function is also ... -
On The Regular Polygons In The Chinese Checker Plane
(University of NairobiDepartment of Mathematics, 26480, Eskisehir, Turkey, 2000)In this paper, we define Chinese checker regular polygons, and determine which Euclidean regular polygons are also Chinese checker regular, and which are not. Finally, we study the problem of existence or nonexistence of ... -
On the Relationship between Satellite-based Evapotranspiration and Normalized Difference Vegetation Index, Case Study: Narok County of Kenya
(University of Nairobi, 2014)This study sought to unearth a possible relationship between evapotranspiration and Normalized Difference vegetation index (NDVI). Daily datasets of Evapotranspiration with a pixel resolution of 3km were sourced from ... -

On the solution of the Fokker-Planck diffusion equation by the path integral method
(Department of Physics, University of Nairobi, 1976)A dynamical system with probability density of state satisfying the Fokker-Planck diffusion equation is considered by starting from a Langevin type of equation. The path integral method is applied in solving the basic ... -
On third order rotatability
(School of Mathematics, University of Nairobi, 1994)Third order rotatability of experimental designs, moment matrices and information surfaces is investigated, using a Kronecker power representation. This representation complicates the model but greatly simplifies the ... -
On Unitary Invariance of Some Classes of Operators
(University of Nairobi, 2020)It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However, under the stronger relation of unitary equivalence ... -
