Oceanic and atmospheric linkages with short rainfall season intraseasonal statistics over Equatorial Eastern Africa and their predictive potential
(University of Nairobi, 2014)Despite earlier studies over various parts of the world including equatorial Eastern Africa (EEA) showing that intraseasonal statistics of wet and dry spells have spatially coherent signals and thus greater predictability ... -
Odor Composition of Preferred (Buffalo and Ox) and Nonpreferred (Waterbuck) Hosts of Some Savanna Tsetse Flies
(College of Physical and Biological Sciences, 2002-05)A previous study on the feeding responses of tsetse flies, Glossina morsitans morsitans, implicated the existence of allomonal barriers, both volatile and nonvolatile, on the nonpreferred host, waterbuck, Kobus defassa. ... -

The Olduvai event at Olduvai Gorge
(University of Nairobi,, 1976)Palaeomagnetic polarity measurements from Beds I and II at Olduvai Gorge are described, and used to define the extent of the Olduvai event in the Olduvai Gorge section. The upper boundary of the event occurs very close to ... -
Oleanolic Acid and other Compounds Isolated from Cordia africana Lam which Inhibit Vancomycin Resistant Enterococcus
(University of Nairobi, 2019)ABSTRACT Introduction: Treatment of microbial infections has become complicated due to increased resistance of microbes to the current drugs. The current study investigates crude extracts and seven compounds from root ... -
Omega 3 and omega 6 fatty acids in human and animal health: An African perspective.
(University of Nairobi, 2014-12)Lipids are essential for plant and animal development, growth and nutrition and play critical roles in health and reproduction. The dramatic increase in the human population has put increasing pressure on human food sources, ... -
On unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)Abstract It is a well-known result in op erator theory that whenever two op erators are similar then they have equal sp ectra even though they do not have to belong to the same class of op erators. However ... -
On a Certain Transformation of Boltzmann Equation
(Department of Physics, University of Nairobi, 1974)An identical transformation of the Boltzmann equation leads directly to an equation of a purely stochastic process. A simple special case is obtained from the well-known formulae of neutron physics on the transition ... -

On A-Commuting Operators
(School of Mathematics, University of Nairobi,, 2012)Two bounded linear operators A and B on a complex Hilbert space are said to ,1.- commute for ,lEe provided that: AB = ABA. In this paper we look for some properties satisfied by the operators A and B so that ,1.= 1. It ... -

On Analysis And Synthesis Operators And Characterization Of The Synthesis Matrix Of A Frame In Terms Of The Frame Operator
(University of Nairobi, 2018)In this research paper we introduce the operators associated with a frame. That is the Analysis and the Synthesis Operators and their basic properties. The structure of matrix representation of the Synthesis operator is ... -
On commutants and operator equations
(School of Mathematics University of Nairobi, 2012)Let B(H) denote the algebra of bounded linear operators on a Hilbert Space H into itself. Given A,B ∈ B(H) define C(A,B) and R(A,B) : B(H) −→ B(H) by C(A,B)X = AX − XB and R(A,B)X = AXB − X. Our task in this note is to ... -
On Comparison of Local Polynomial Regression Estimators for P=0 and P=1 in a model based framework
(Canadian Center of Science and Education, 2018-07)This article discusses the local polynomial regression estimator for P=0 and the local polynomial regression estimator for P=1 in a finite population. The performance criterion exploited in this study focuses on the ... -
On improved estimation under additional information
(Taylor & FrancisDepartment of Mathematics University of Nairobi, 1988)An improvement of the ordinary least squares estimator of the regression vector in a univariate linear model is obtained. This is done by combining observed data with prior information and other additional information. ... -
On line determination of thermophysical properties in an absorption calorimeter
(University of Nairobi, 1997)A Microsoft FORTRAN 77 algorithm for calculation of the thermal absorptance and emittance of materials for solar photothermal applications is presented. It replaces the Mathematica software package used for an earlier paper ... -
On Local Linear Regression Estimation In Sampling Surveys
(2017-10)A model-based survey is employed to estimate the unknown values of the survey variable, using the local linear regression approach. In particular, a local linear regression estimator in model-based surveys is studied. ...
