Normal Distribution In Historio-Philosophic Context
(University of NairobiSchool of mathematics,, 1998)In general the set-up of the research work has a logical intention. That is the chapters and their respective sections are logically arranged so that one can read and arrive at the results ... -
Normal mixtures in finance: a comparative study and applications
(University of Nairobi, 2013)Many studies on modelling return distributions of financial assets have been conducted. Among them, the most used three-type distributions are the normal, the lognormal and the non-Gaussian stable distributions. Other ... -
The normal titre range of widal and brucella agglutination tests in a cross section of the human population in Nairobi and Naivasha
(Department of Botany, University of Nairobi, 1994)A survey of the literature revealed that among infectious diseases, typhoid fever and brucellosis are widespread in Kenya; the Widal's and Brucella agglutination tests are still widely used in the diagnosis of these ... -

Nuclear Forensic Analysis via Machine Learning Assisted Laser-based Spectroscopy and Spectral Imaging
(University of Nairobi, 2022)Nuclear forensics (NF) is a systematic and scientific methodology designed to identify, categorize, and characterize seized nuclear and radiological materials (NRM). The aim of NF is to reveal the geographical origin, ... -
Nuclear Forensics Analysis Of Fission Products By Means Of Chemometric Laser Induced Breakdown Spectroscopy
(University of Nairobi, 2018)In the wake of the current global nuclear renaissance, the threat of terrorism involving nuclear materials is real. The lethality involving detonated improvised nuclear devices (IND) “dirty bombs” or even radiological ... -
Nucleotide Diversity of Common Bean Phaseolin (α-phs) Gene and Its Association With Seed Protein Content
(University of Nairobi, 2022)Phaseolin (α-Phs) is the most abundant protein reserve in seeds of common beans accounting for 40 – 50 % of the total seed protein. Despite having low methionine (0.5 - 0.80 %) content, phaseolin is the primary source of ... -
Numerical Bifurcation Analysis For Advective-Diffusive Equations In Climate Modelling
(University Of Nairobi, 2016)The earth's climate system is a highly complex, interconnected system formed by the atmosphere, land surface, ocean and snow together with all living organisms and powered by the solar radiation. Mathematical models have ... -
