Characterization of Operators of Class G1 , Spectral G1 ,Class loc- G1 & Spectral loc- G1 in a Hilbert Space
(University of Nairobi., 2012)
Life history of Oplostomus haroldi (Coleoptera: Scarabaeidae) under laboratory conditions and a description of its third instar larva
(2/2/2012)
The life history of Oplostomus haroldi (Witte), a recently reported pest of honeybee colonies in East Africa, was studied for the first time under laboratory conditions. Adult O. haroldi collected from beehives in the ...
Application of Dye-Sensitized Solar Cell Technology in the Tropics: Effects of Air Mass on Device Performance
(2012)
Effects of air mass on the performance of a dye-sensitized solar module (DSSM) have been investigated in a tropical
area in Nairobi, Kenya. Outdoor measurements were performed at different times on different days and a ...
A note on metric equivalence of some operators
(Pushpa Publishing House, Allahabad, INDIA, 2012)
In this paper, we study the metric equivalence relation and closely
related relations on some classes of operators. We describe the spectral
picture of metrically equivalent operators. We give some conditions
when metric ...
Using Adaptive Link Hiding to Provide Learners with Additional Learning Materials in a Web-Based System
(Research Center for Educational Technology, 2012)
This article reports results from a web-based online learning experiment that provided learning support to
students in an object-oriented programming course. This support was intended to assist learners in
acquiring ...
Filling the Digital Divide in Rural Connectivity Case for Last Mile Mobile Broadband Subscription
(2012-12)
Access to Information and Communication Technologies (ICTs) has been found to have a correlation with socio-economic development and gross domestic product. Despite efforts by governments across
Africa to revamp the ...
On the Minimal Entropy Martingale Measure and Multinomial Lattices with Cumulants
(2012)
In this article, we describe with relevant examples based on empirical data how to
use the minimal entropy martingale measure (MEMM) to price European and American Options
in multinomial lattices which take into account ...
On spectral properties of -commuting operators in Hilbert spaces
(2012)
Let B(H) denote the Banach algebra of bounded linear operators on a complex Hilbert
space H and let A;B 2 B(H) satisfying the equation; AB = BA; 2 C;AB 6= 0, where C
denotes the complex number eld. In this case A and ...
Temperature-dependent feeding interactions between two invasive fishes competing through interference and exploitation
(University of Nairobi, 2012-06)
Context-dependent ecological interactions between invasive species are important in determining the outcomes of their introductions. The consequences of competitive interactions between the Nile tilapia Oreochromis niloticus ...
