Role of bismuth and substrate temperature on the optical properties of some flash evaporated se100-x bix glassy system
(University of Nairobi, Kenya, 2015)
Chalcogenide glasses are very important in the modern technology especially selenium-based. These
glasses are sensitive to electromagnetic radiation useful in the infrared optics. The study investigated the effect of ...
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Cornell University, 2021)
In this article we apply algebraic operator ordering property of the basic atom and field operators to construct and prove conservation of the excitation number operator of the anti-rotating (anti-Jaynes-Cummings) component ...
Kenya-Ethiopia Relations: a Study of the Significance of Economic and Political Factors Contributing to Co-operation, 1963-1991
(Nairobi university, 2005)
This thesis analyses and explains the nature of inter-state relations between Kenya and Ethiopia. An analysis of the two countries' relations shows that despite change of leadership in both Kenya and Ethiopia and despite ...
Complex Spacetime Frame: Four-Vector Identities and Tensors
(Scientific Research Publishing, 2014)
This paper provides derivation of some basic identities for complex four-component vectors defined in a complex four-dimensional spacetime frame specified by an imaginary temporal axis.
The resulting four-vector identities ...

Investigation of the effect of film thickness on the optical properties of amorphous Se85-xte15sbx thin films
(Africa Journal of Physical Sciences, 2014)
Amorphous thin films of Se85-xTe15Sbx (x = 0.0, 0.5, 2.5, and 5.0 at. %) deposited by flash evaporation technique,
have been investigated in the wavelength range of 500nm-3000nm. It is found that the effect of increasing ...
Devolved ethnicity in the Kenya: Social, economic and political perspective
(Sciendo, 2018)
act
This paper examines the ethnicity as an issue prevailing upon the Kenyan society and its implication on
the social, economic and political dimensions in Kenya. Devolved ethnicity has been seen to be on the arise
since ...
Occurrence characteristics of equatorial plasma bubbles over Kisumu, Kenya during Solar maximum of Solar Cycle 24
(International Journal of Advanced Astronomy, 2021)
Equatorial Plasma Bubbles (EPBs) are irregular plasma density depletions in the ambient electron density in the equatorial F-region ion osphere generated after sunset. EPBs are known to bring disruptions to telecommunication ...
On the Solution of n-Dimensional Regular Cauchy Problem of Euler-Poisson-Darboux Equation (EPD)
(2017)
A general exact solution to the n-dimensional regular Cauchy prob-
lem of Euler-Poisson-Darboux (EPD) equation has been studied. Firstly,
the general exact solution for the one dimensional regular Cauchy prob-
lem of ...
Exact analytical solutions for fully quantized parametric oscillation dynamics
(Routledge, 2013)
In this paper, a simple method for obtaining general analytical solutions of the time evolution equations for a fully quantized parametric oscillation process is developed. Heisenberg’s equations for the signal–idler photon ...
