Analysis of CSRZ and CSNRZ Coding for DQPSK and OQPSK Transmitter Configurations for Optical Microwave Generation Signals Based on Stimulated Brillouin Scattering
(World Scientific News, 2020)
The use of Carrier Suppressed Non-Return to Zero (CSNRZ) and Carrier Suppressed Return to
Zero (CSRZ) modulation formats in Dense Wavelength Division Multiplexing (DWDM) channels at 1
Gb/s and 10 Gb/s is investigated. ...
Improving Students’ Application of Moment of Force Concepts in Physics through Experimental Approach, a case of Secondary Schools in Marakwet West Sub-County, Elgeyo Marakwet County, Kenya
(African Journal of Education, Science and Technology, 2021)
An investigation was carried out to ascertain the effectiveness of experimental
approach on students’ application of moment of force concepts in Physics in secondary
schools in Marakwet West Sub-county, Elgeyo Marakwet ...
Computation of the Expectation Value of the Electron – Phonon and Coulomb Interaction Hamiltonian using Second Quantization and Many Body Techniques
(International Journal of Research and Analytical Reviews (IJRAR), 2020-12)
The problem of the strong electron coupling in the theory of superconductivity has been discussed in many studies on the basis of electron and phonon spectral functions. For the rationale of investigating the effect of ...
Design of simultaneous multicolor coherent light generation in a single MgO:PPLN bulk crystal
(Journal of the Optical Society of America B, 2020-11)
We report on simultaneous sum-frequency mixing and doubling of C-band and 980 nm laser sources using a
single segmented periodically poled lithium niobate (PPLN) crystal in a single-pass configuration. Our theoretical
analysis ...
Landau Criteria of Superfluidity of Two Component Mixture of Bosons
(International Journal of Recent Research Aspects, 2020)
Using the quasi-particle energy of a mixture of two-component gas of bosons which is assumed to be in a
superfluid state, the Landau criterion for superfluidity has been applied to obtain the magnitude of the Landau’s ...
INTEGRATION OF VCSEL WITH MODULATED RAMAN PUMP FOR DATA AND CLOCK TRANSMISSION IN OPTICAL COMMUNICATION
(University of Eldoret, 2022)
The evolution of ultrafast optical technologies has led to the realization of low cost,
low latency and high speed optical networks. Existing telecommunication
infrastructure does not provide sufficient capacity to satisfy ...
Ab initio insights into Graphene-Zirconium disulfide/diselenide heterostructure as electrode material for alkali-ion batteries
(Surfaces and interfaces, 2021)
In the search for an energy storage medium with higher electronic conductivity, rate performance and moderate volume expansion, van der Waals heterostructures
are a promising alternative. Herein, the potential of graphene ...
Frequency stability characterization: DFB laser and Raman pump performance on a distributed clock signal over 24.69 km fiber
(Journal of the Optical Society of America, 2020-07)
Distribution of timing and frequency signals in a fast-changing world requires unprecedented levels of stability for
characterization.Transfer of frequency references over long distance without introducing any additional ...
IN SITU TECHNO-ENVIROECONOMIC ANALYSIS OF A ROOFTOP PHOTOVOLTAIC (PV) BACKUP SYSTEM IN THE TROPICAL CLIMATE
(University of Eldoret, 2022-07)
Solar PV generators are increasingly being deployed in the built environment as stand-alone or backup power systems to supply electricity either solely or during power outages respectively. Diesel generators (DGs) are ...
Mechanical and Elastic Properties of Selected 211 MAX Phases: A Density Functional Theory Study
(Kabarak Journal of Research & Innovatio, 2023-10)
MAX Phases are a class of ternary materials that have continued to play a greater role in the field
of materials science due to their unique properties that bridge the gap between metals and ceramics
which have uses in ...
