Objectivity and personal involvement in artificial intelligence: An examination of the Turing Test
(2004)The aim of this report is to study what an intelligent system entails. The study focuses on what makes natural intelligent system. This will be important in that it will form a guideline for the construction of ... 
The Occurrence Of Aspergillus Section Flavi In Soil And Maize From Makueni, County, Kenya
(University of NairobiSchool of Biological Sciences, 2013)Maize (Zea mays L.) is the staple food for most households in both urban and rural areas in Kenya and has an estimated annual per capita consumption of about 125 kg per person, which is among the highest in the world. Ear ... 
Occurrence of heavy metals in sediments, fish and oysters from Mtwapa, port Reitz, Makupa and Shirazi creeks along the Kenyan coast
(Department of Zoology, University of Nairobi, 2002) 
Occurrence, mineralogical composition and significance of laterites in Kenya
(University of NairobiGeology, 2011)The study area is Kenya a country in Eastern Africa bordered by Ethiopia to the north, Somalia to the east, Tanzania to the south, Uganda to the west, and Sudan to the northwest, with the Indian Ocean running along the ... 
Of Kopovikins Theory
(University of NairobiSchool of mathematics,, 1990)Tde by now classical tlleorem of P.P. Korovkin first appeared in [6] in 1953. It arose from the study of the role of Bernstein polynomials in the proof of the Weei rs trass approximation ... 
OLR and SST characteristics over Africa during years of deficient and surplus rainfall in East Africa
(Department of Meteorology University of Nairobi, 1994)Accurate rainfall forecasts would greatly improve the quality and quantity of agricultural products and other rain dependent activities, while allowing for the amelioration and integration of the catastrophic socioeconomic ... 
On some application of algebra and geometry in coding theory
(School of mathematics, 201108)The fundamental problem that led to the development of the theory of error correcting codes was that of having a reliable communication over unreliable channels. A commu nication channel can be as simple as the air ... 
On almost similarity and other related equivalence relations of operators in Hilbert spaces
(University of Nairobi, 201607)In this thesis, we study unitary equivalence, similarity, quasisimilarity, almost similarity and metric equivalence of operators acting on separable Hilbert spaces. We also study the Murrayvon Neumann relation of ... 
On classification of simple plane curve singularities
(University of Nairobi, 2015)In this pro ject we aim to classify simple plane curve singularities by considering simple plane curve singularities as quotient singularities in C2 by a finite subgroup G ≤ SL(2, C). We also review McKay correspondence ... 
On Decomposition of Operators in Hilbert spaces
(University of Nairobi.School of Mathematics, 1999) 
On econometric modelling and time series models
(School of Mathematics, University of Nairobi, 1997)In this thesis an attempt is made to synthesize time series modelling with econometric models through the notion of duality. More specifically an extension of the type of models presented by Zellner (1979) is attempted ... 
On equivalence of some operators in hilbert spaces
(2014)Unitarily equivalence is the natural concept of equivalence between Hilbert space operators. Thus, this concept is the building block of other equivalence relations such as similarity, quasisimilarity, or even metric ... 
On extensions of closable operators for the case of a whole plane, a half plane, a strip or a line
(University of Nairobi, 2015) 
On fractional fourier transform and the schrodinger equation of harmonic oscillation
(2005)The Fractional Fourier Transform (FRFT) is a timevarying spectrum analysis technique for nonstationary signals and processes. In recent years it has attracted a considerable amount of attention, resulting in many ... 
On fredholm and weyl operators in hilbert spaces
(School of mathematics, 201108)This project deals with Fredholm, Weyl and Browder operators in Hilbert spaces. Chapter one is t be int.rorl uct.iou part whore not at ions and detin it ions are gIven. Chapter two tackles Fredholm operators by form ... 
On invariance of the numerical range and some classes of operators in Hilbert spaces
(School of Mathematics, University of Nairobi, 2013)In this thesis the invariance of the numerical range under isometric similarity is examined. It is a well known fact that unitarily similar operators have the same numerical range. Chapter one is devoted to basic ... 
On irreducible representations of Sn
(School of mathematics,University of Nairobi, 200906)As mentioned in [8], A group representation can be thought of as an action oi a group G on some vector space. Such actions arise naturally in many branches oi mathematics and physics and as such it is important to study ... 
On probability of ruin in retirement based on contribution rates in a pension scheme
(School of Mathematics, University of Nairobi, 2009)The main objective of this dissertation was to show that contribution rates can be used to minimize the probability of financial ruin in retirement within a pension scheme within the Kenyan pension industry and help ... 
On quasiaffinity, equivalence and intersection of some classes of operators in hilbert spaces
(School of Mathematics, University of Nairobi, 2001)In this thesis, chapter one is on introduction, notations and terminology that will be used in the chapters to follow. Also shown is a counter example of a quasiaffinity operator which is not invertible 
On quasisimilarity, almost similarity and metric equivalence of some operators in hilbert spaces
(School of mathematics, 201208)In the first chapter we give a brief introduction on some of the developments of the equivalence relations came about. We also define some of the notations and terminologies that will be used in this work. The second ...
