ROLE OF LONG – RANGE ELECTRON - PHONON AND COULOMB INTERACTIONS IN HIGH - TC CUPRATE SUPERCONDUCTORS
(University of Eldoret, 2016)Superconductivity is the disappearance of the electrical resistance of certain materials at certain critical temperatures called transition temperatures. This phenomenon was discovered in 1911 and is one of the most ... -
ROTATING OPTICAL BEAMS: DIGITAL HOLOGRAPHIC GENERATION, PROPERTIES AND SELF-RECONSTRUCTION DYNAMICS
(2016-05-19)This thesis reports on an experimental investigation of rotating optical beams. Superpositions of higher-order Bessel beams with rotating intensity profiles were generated using a digital holographic experimental technique ... -
ROTATING OPTICAL BEAMS: DIGITAL HOLOGRAPHIC GENERATION, PROPERTIES AND SELF-RECONSTRUCTION DYNAMICS
(University of Eldoret, 2013)This thesis reports on an experimental investigation of rotating optical beams. Superpositions of higher-order Bessel beams with rotating intensity profiles were generated using a digital holographic experimental technique ... -
SIMULATION OF NOT-, AND- AND OR- OPTICAL GATES USING WIDEBAND TRAVELLING WAVE SEMICONDUCTOR OPTICAL AMPLIFIER
(University of Eldoret, 2016)All optical gates have received practical applications in the recent past. This is due to its high demand in optical communication networks in this age of Information Technology (IT). They have assisted in performance of ... -
STIMULATED BRILLOUIN SCATTERING (SBS) CHARACTERIZATION IN MODERN FIBRES AND A TECHNIQUE OF SLOW LIGHT GENERATION
(University of Eldoret, 2015)Stimulated Brillouin scattering (SBS) is one of the recent technology that is being developed to generate slow light in optical fibres. It is one of the simplest and most applicable methods of slow light production. Slow ... -
SYNTHESIS, GROWTH AND PHYSICO-CHEMICAL PROPERTIES OF TITANIUM DIOXIDE NANOTUBES FOR PHOTOCATALYTIC WATER PURIFICATION
(2018)Titanium dioxide (TiO2) photocatalysis is a promising method for decomposition of organic contaminants in water and belong to new a class of water purification methods called advanced oxidation processes (AOPs). AOPs ... -
THEORETICAL ANALYSIS OF A SOLAR AIR COLLECTOR WITH A RECTANGULAR AIR-DUCT PROFILE
(University of Eldoret, 2012)Any solar energy conversion system requires proper designing and sizing in order for it to be cost effective with respect to energy production under the prevailing climatic conditions and initial cost. Modelling and ... -
THEORETICAL DETERMINATION OF SPECIFIC HEAT AND CRITICAL TEMPERATURE OF HIGH-TC CUPRATE SUPERCONDUCTORS BASED ON INTRALAYER AND INTERLAYER INTERACTIONS
(University of Eldoret, 2013)The role of attractive interlayer and intralayer interactions in layered high-Tc Cuprate superconductors was investigated using a two-layer Hamiltonian. The Hamiltonian was formulated and diagonalized using Bogoliubov ... -
THERMODYNAMIC PROPERTIES OF HIGH TEMPERATURE SUPERCONDUCTORS BASED ON THE t-J-d MODEL
(University of Eldoret, 2015)Many theories that attempt to describe the superconducting state have suffered significant failures, leaving the t-J model as the only model which effectively captures the physics of the strong correlations inherent ...
