AN ESTIMATE OF VELOCITY PROFILE IN LAMINAR BOUNDARY LAYER
(Academic Publications, Ltd., 2011-09-02)
This paper examines the boundary layer thickness developed for an
incompressible viscous fluid flowing over a flat plate. The solution of the Blasius
problem is considered. In this paper, the authors propose a polynomial ...
Multipole expansion of integral powers of cosine theta
(Nature Publishing Group, 2020-11-18)
Legendre polynomials form the basis for multipole expansion of spatially varying functions. The technique allows for decomposition of the function into two separate parts with one depending on the radial coordinates only ...
Effect of Ga Incorporation and Film Thickness on the Optical Properties of as-Deposited Amorphous GaxSel-x Thin Films
(University if Nairobi Research archive, 2014)
Flash evaporated amorphous GaxSe1-x (x = 0, 1, 2, 3, and 4 atomic %) on glass substrates have been
investigated within a 500nm-1500nm spectral range. Film thicknesses explored were ; 200±10nm, 265±10nm,
330±10nm, and ...
Symmetry conjugates and dynamical properties of the quantum Rabi model
(Cornell University, 2021)
Symmetry transformations have proved useful in determining the algebraic structure and internal
dynamical properties of physical systems. In the quantum Rabi model, invariance under parity symmetry transformation has been ...
3-DIMENSIONAL MATHEMATICAL MODELLING OF TEMPERATURE DISTRIBUTION IN POROUS MEDIA
(Academic Publications, Ltd., 2011)
An alternative method of the numerical solution of the heat equation is presented. A three-dimensional modelling approach is used in this paper rather than one or two dimensional models in order to account for the lateral ...
Quantum thermodynamics of a strongly interacting bose-fermi mixture in a three-dimensional anharmonic potential
(Research gate, 2016)
ABSTRACT
Thermodynamic properties of Bose-Fermi mixture at ultra-low temperatures were studied using
perturbation theory in three Cartesian coordinates. The Hamiltonian for the mixture was developed in
terms of boson-boson, ...
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 ...
The benefits and challenges emanating from community policing in Kenya: A Criminological Perspective
(International Journal of Innovation and Scientific Research, 2014)
Community policing is an integral component in ensuring that there is no insecurity in the community. More so,
the Kenyan government in the Kibaki regime introduced the concept of community policing which was seen as ...
Finite Difference Analysis of 2-Dimensional Acoustic Wave with a Signal Function
(2015-12-09)
This paper describes progress on a two dimensional numerical simulation of acoustic wave propagation that has been developed to visualize the propagation of acoustic wave fronts and to provide time-domain signal. In this ...
Comparative Investigation of Fullerene PC 71 BM and Non-fullerene ITIC-Th Acceptors Blended With P3HT or PBDB-T Donor Polymers for PV Applications
(Frontiers, 2021)
Fundamentally, organic solar cells (OSCs) with a bulk-heterojunction active layer are
made of at least two electronically dissimilar molecules, in which photoabsorption in one
(donor) generates Frenkel excitons. The ...
