On reflectionless equi-transmitting matrices
(2014)Reflectionless equi-transmit.ting unitary matrices are studied in connection to matching conditions in quantum graphs. All possible such matrices of size G are described explicitly. It is shown that such matrices form 30 ... -
ON SMOOTHING TIME SERIES DATA USING A CLASSICAL MOVING AVERAGE FORMULA
(Department of Mathematics, University of Nairobi, 2002)In time series realizations, assuming that the trend component to be approximated by a polynomial in time, smoothing filters based on a moving-average formula are proposed which link the degree of this polynomial to the ... -
On sociology and behaviour in impala (aepyceros (melampus lichtenstein)
(University of Nairobi, 1966-08)1. The required habitat of impala, association with other herbivores and the relation to predators are outlined. 2. The commonest types of group formation - female herd with dominant male and bachelor herd - and the ... -
On spectral properties of -commuting operators in Hilbert spaces
(School of Mathematics, University of Nairobi, 2012)Let B(H) denote the Banach algebra of bounded linear operators on a complex Hilbert space H and let A;B 2 B(H) satisfying the equation; AB = BA; 2 C;AB 6= 0, where C denotes the complex number eld. In this case A and ... -
On Statistical Modelling Of Floods And Drought Insurance Products For Developing Countries
(School of Mathematics, 2006)Probabilistic models have been used to measure risk, the chance of occurrence of unfavourable events. The extend of damage may then take the form of a random variable. In this paper we follow such an approach to arrive at ... -
On stock returns volatility and trading volume of the nairobi securities exchange index
(University of Nairobi, 2020)This study attempts to put forward a framework that can be utilized to model the dynamics of the underlying returns on asset. The intention is to probe the dynamic connection between volatility of stock returns and trading ... -
On Support Vector and Relevance Vector Machines

On the Accuracy of Quadrature Laplace Transform Inversion and the Solution of State Space Equations
(University of Nairobi.Department of Mathematics, 1978)A quadrature formula is shown to be an approximation of the power-series method of inverting Laplace transforms. This together with the properties of the constants derived from a power-series expansion of the Padé approximation ... -
On the characterization of Class R_1 of non-normal operators in a Hilbert space
(Department of Mathematics, College of Biological and Physical Sciences, University of Nairobi, 2012) -
On The Conventional Approaches To The BBGKY Hierarchy.
(University of Nairobi.School of Physical Sciences, 1977) -
On the Coordinate, Energy and Angular Momentum Preparation of the Density Matrix.
(University of NairobiDepartment of Physics, 1995)Abstract Not Available -
On The Dual Bishop Darboux Rotation Axis Of The Dual Space Curve
(University of NairobiDepartment of Mathematics, Usak, Turkey, 2000)In this paper, the Dual Bishop Darboux rotation axis for dual space curve in the dual space D3 is decomposed in two simultaneous rotation. The axes of these simultaneous rotation are joined by a simple mechanism. -
On the effects of random forces in non uniformly distributed dynamical system
(University of Nairobi, 2010)Interaction of a dynamical system with stochastic source R(t) is studied using parabolic type equation on a circle of length 2L.Greens function for the system is constructed and it is shown that almost all the correlation ... -
On the efficiency of testing procedures in the linear model for multivariate longitudinal data
(School of Biological Sciences, 2011)Multivariate data collected over time on the same experimental unit, referred to as multivariate longitudinal data, are typical of many agricultural, biological, clinical and medical studies. One way to account for the ... -
On The Estimation Of Global Solar Insolation
(University of Nairobi, 1983)A curve suitable for estimation of global solar energy insolation in equatorial regions has been generated from humidity considerations using an empirical “universal” formula and experimental solar insolation data recorded ... -
On the evaluation of the molluscicidal properties of Polygonum senegalense
(University of NairobiCollege of biological and physical science, 1977) -
On the existence of a non-relativistic hermitian time operator
(2016)The existence of a hermitian time operator is proposed in the framework of non-relativistic quantum mechanics.The Heisenberg equation of motion is shown to yield constant rate of flow of time.It is shown to yield results ... -
