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 ... 
Older Adults And Technology Adoption: Investigating The Use Of Online Banking Among The Seniors In Nairobi County
(UoN, 2019)The overall global diffusion of technology into many domains of banking and financial services has accelerated the shift from traditional banking methods to more ICTbased such as Online Banking. Convenience and efficiency ... 
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 Aluthge Transforms and Spectral Properties of different classes of operators in Hilbert spaces.
(University of Nairobi, 2020)For any linear operator T acting on a Hilbert space H, its Aluthge transform T˜ where T˜ = jTj 12 UjTj 12 is another linear operator on H: It is known that T˜ preserves the spectral properties of T and more importantly ... 
On Application Of Operator And GroupTheoretic Concepts In Signal Processing And Cryptography
(UoN, 2019)In this thesis we have studied how operator theory is applied in signal processing and how some concepts in group theory are crucial in the design of cryptosystems and their use in hiding information. A frame is a redundant ... 
On Applications of Operators and Group  Theoretic Concepts in Signal Processing and Telecommunication
(University of Nairobi, 2017)Operator theory concepts such as frame operator, Gramian operator, synthesis operator and analysis operator are useful in signal processing and telecommunication. Finite dimensional Hilbert spaces and normalized (unit) ... 
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 and topology of invariant subspaces
(University of Nairobi, 2018)In this project we investigate the invariant and hyperinvariant subspace lattices of some operators. We give a lattice theoretic description of the lattice of hyperinvariant subspace of an operator in terms of its ... 
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 Finite Gamma Mixtures and Their Properties
(University of Nairobi, 2021)The concept of finite mixture has contributed immensely in search of more flexible distributions that are in a position to capture data heterogeneity. One parameter Lindley distribution as the first case of a finite mixed ... 
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 ...
