. Application of banach space ideal properties in image transmission over wireless network
(2014-03)The Banach space operator ideals and nuclear maps have a large class of morphisms which behave as if they were part of a compact closed category, that is, they allow one to transfer variables between the domain and the ... -
Automation of pressure and temperature measurements in vacuum deposition systems
(2013-08)This paper describes a simple automated instrumentation and measurement system that is designed to offer a more reliable and fast method of measuring temperature and pressure, in thin film deposition systems. ... -
Conjecture of banach space operator ideals in nuclear spaces
(2013-06)We apply the notion of Banach space operator ideals in nuclear spaces through topological vector spaces. The motivation for this study came from attempts to generalize the structure of nuclear spaces as a result of nuclear ... -
The effect of organic binders on the fracture properties of kaolin refractories, Journal of Material Science
(Springer, 2008-06)The fracture properties of kaolin-based refrac-tories prepared using plant-derived binders from okra and‘‘mrenda’’ have been investigated and compared. It wasobserved that the MOR of fired samples improved ... -
“Effect of AC Helmholt magnetic field on the mass of Rosecoco deans”
(Taylor and Francis Online, 2011-06-09)Plastic bags mostly made of polyethylene (PE) cause pollution as solid waste due to their non-degradability nature. Initiation of a degradative process by enhanced photo-oxidation is a possible method for an accelerated ... -
Study of Humidity and UV Wavelength Effects on Degradation of Photo-Irradiated Polyethylene Films Using DMA
(2011-06-09)Plastic bags, mostly made of polyethylene, cause pollution as solid waste due to their nondegradable nature. Accelerated degradation, as a solution to mitigate the menace, can be achieved through moisture enhanced photolysis. ... -
“The startling effect of the sound of C. Afra And A. Tormotus on the female A. gambiae”
(2012)The female Anopheles gambiae, a malaria vector, detects ultrasound by its antenna, initiating an attractive or repulsive response. Modern electronic mosquito repellents exploit this concept in attempt to control malaria, ... -
A Comparative study of the transmission parameters of the sound of mosquito predators and EMR”
(2012)The wide bandwidth EMR ultrasound, exploited in mosquito repellency, yielded only 20 % effectiveness. Due to this wide bandwidth, ultrasound from Amolops tormotus and Coleura afra, mosquito predators, was investigated. The ... -
Determination of Hall Effect Parameters of Gallium Arsenide and Gallium Manganese Arsenide by Van Der Pauw Geometry
(2012)Gallium Arsenide (GaAs) has been used widely in electronic industry to make diodes and transistors. As a semiconductor, it can be doped up with impurities with magnetic properties such as manganese to increase its electron ... -
Determination of optical band gap and heat dissipation of Ga1-xMnxAs with Light in UV-VIS-IR Region using OSA SPECTRO 320”,
(International Knowledge Sharing Platform, 2012)Heat generated by silicon-based transistors due to high energy photo irradiation interferes with the electronic conductivity of transistors in the ICs. There is need to search for an alternative semiconductor material ... -
Synthesis and electrochemical studies of heterobinuclear complexes containing copper and molybdenum nitrosyl groups linked by Schiff base ligands
(Springer, 2000-08)Abstract The reaction of [MoCl(NO)Tp * = tris(3,5-dimethylpyrazolylborate] with copper Schiff base complexes derived by condensation of one mole each of 2,5-dihydroxybenzaldehyde and salicylaldehyde with α,ω diamines ... -
Synthesis, characterization and electrochemistry of heterobimetallic complexes containing molybdenum(II) nitrosyl and manganese(II)-schiff base centers
(Chemical Society of Ethiopia, 2010)New complexes derived from the reaction of Mo (NO)Tp *Cl2; Tp * = tris(3,5-dimethylpyrazolyl) borate with a series of manganese(II) Schiff bases have been synthesized. Characterization by UV, IR, MS and elemental analysis ... -

(Chemical Society of Ethiopia, 2010)ABSTRACT. ABSTRACT New complexes derived from the reaction of Mo(NO)Tp *Cl2; Tp * = tris(3,5-dimethylpyrazolyl) borate with a series of manganese(II) Schiff bases have been synthesized. Characterization by UV, IR, MS ... -
Analysis of Volatility of Real Exchange Rate and Exports in Kenya using the Garch Model: 2005:2012
(2015)Abstract The real exchange rate has proven to be an important factor in international trade because it is expected that exports respond to real exchange rate movements with respect to the characteristics of the ... -
Modeling and Forecasting Kenyan GDP Using Autoregressive Integrated Moving Average (ARIMA) Models
(Science Publishing Group, 2016-01)The Gross Domestic Product (GDP) is the market value of all goods and services produced within the borders of a nation in a year. In this paper, Kenya’s annual GDP data obtained from the Kenya National Bureau of statistics ...
