Near Real Time Machine Driven Signature Detection, Generation and Collection
(University of Nairobi, 2015)Internet worms can spread very fast and cause losses both in terms of lost business opportunities as well as human resources required to alleviate the caused damages. There exists two ways of protecting against the worms ... -
Negative Binomial Distributions For Fixed And Random Parameters
(University of Nairobi, 2014)The first objective of this project is to construct Negative Binomial Distributions when the two parameters p and r are fixed using various methods based on: Binomial expansion; Poisson – Gamma mixture; Convolution of ... -
Negative binomial Mixtures, construction of negative binomial mixtures and their properties
(Mathematical Statistics, university od Nairobi, 2013)The objective of this project was to construct Negative Binomial mixtures. We consider a class of mixture distributions generated by randomizing the success parameter p and fixing parameter r of a Negative Binomial ... -
Negative Binomial-three Parameter Lindley Distribution and ITS Properties
(University of Nairobi, 2023)In this study, we introduce a mixed distribution by mixing the distributions of negative binomial and three Parameter Lindley distribution This new mixed distribution has a thick tail and may be considered as an alternative ... -
Nematode response to soil organic amendments in a semi-arid region under soybean (Glycine max), Naivasha, Kenya.
(University of Nairobi, 2016)Agricultural production within the smallholder farming sector of East Africa is constrained by numerous factors including parasitic nematodes. Existing control measures involving applications of chemical nematicides are ... -
Nematodes Attacking the purple Passion Fruit (passiflora Edulls) Plants In Kenya And Studies On The Biology Of Two Common Species, Meloidogyne Javanica And M. Incognita With Special Reference To their Pathogenicity And Chemical Control
(University of Nairobi, 1993)In a survey of plant parasitic nematodes on passion fruit in Kenya 10 genera of nematodes were discovered. Of these, 8 were identified to species level, two of which attempts were made to determine the existence of races. ... -
Network impact analysis of security attacks in mobile ad hoc networks
(University of NairobiSchool of Computing and Informatics, 2012)Mobile ad hoc networks also known as MANETs have been used extensively for the seamless provisioning of information exchange, where the deployment of infrastructure is difficult, if not impossible. Such cases include ... -
Network intrusion monitoring and reporting using e-mail and sms
(School of Computing and Informatics, 2012)The fundamental problem with any security administrators today is its ability to cope with the rising amount of network intrusions. Network security is fast becoming an absolute necessity to protect the information ... -
Neural Network - Based Predictive Analytics of Covid-19 in the Health Sector for Decision Support in Kenya
(University of Nairobi, 2022)COVID-19 spread rapidly across the globe and claimed many lives. As a result, it was declared a pandemic. Kenya, like most countries was negatively affected by the disease. In the face of COVID-19, predictive analytics ... -
A neural network implementation for near real time tropospheric water vapour profiling over Nairobi using ground-based gps receiver
