Global asymptotic behavior of an aquatic system with periodic nutrient supply
(University of NairobiSchool of Physical sciences, University of Nairobi, 2005-09)We study the dynamical properties of a chemostat model in which two species compete for a periodically supplied, growth-limiting nutrient. We exploit the well known basic properties of the model to study the behaviour ... -
Spatial analysis of tree species occurrence using generalized linear model and bayesian approach: a case study of Mt. Kenya region
(School of Mathematics, University of Nairobi, 2007)The development of predictive distribution models has become important in making predictions about occurrence of species based on variables derived from remote sensing or Geographical Information System (GIS). This project ... -
Roads-Information Database and Maintenance-System Kiambu District, Kenya
(School of Computing and Informatics, University of Nairobi, 2005)Thepurpose of this project was to develop a Roads Information Database and Maintenance System forKiambu District, Kenya that allows users to have several views of the entire road network in the district and provide ... -
The Aberdare ecosystem: its bio-economic functions, interactions and problems of management
(University of NairobiSchool of Biological Sciences, University of Nairobi, 1977-01)The 'raison d'etre' of this study is the search for a sound conceptual base upon which to pivot and direct rational managementdecisions for the Aberdare Forest and National Park. The general research activity revolved around ... -
Optimal designs for models with covariates
(School of Mathematics, University of Nairobi, 2006)The model refers to a treatment design with one treatment at v levels and first Order regression on K continuous covariates attached to each experimental unit. The Problem is that of constructing optimal completely ... -
Climatological probability forecasting of rainfall in Kenya
(School of Mathematics, University of Nairobi, 2003)Climate variability has significant impact on performance of the economy of a country especially in a developing country like Kenya. Certain sectors of the economy like agriculture, manufacturing, transport and communication ... -
Application of credibility theory in the rating of micro-insurance products
(School of Mathematics, University of Nairobi, 2008)This paper discusses how credibility theory can be used in rating a micro insurance product. It starts by defining micro insurance and explaining its role in an economy and particularly for the low income group. The paper ... -
Support vector machines: A Critical empirical evaluation
(School of Computing and Informatics, University of Nairobi, 2003)The main focus of this thesis is Support Vector Xlachines (8\-:'1s). In particular, we first investigate empirically whether they live up to the claims made, i.e. they suffer less from class imbalances, noise and ... -
A framework for efficient & effective utilisation of ICT in the insurance sector in Kenya
(School of Computing and Informatics, University of Nairobi, 2007)Traditionally, Insurance industry in Kenya has been associated with a lot of inefficiencies and being ineffective especially when it comes to settlement of claims. In the recent past however, some prominent changes ... -
Classification problems in Dorfrnan-Sterrett group-screening designs
(School of Mathematics, University of Nairobi, 2006)This thesis is a study on the Dorfman-Sterrett group-screening designs assuming equal a-prior probabilities of items being defective. Based on a clear theoretical framework, we have studied both restricted and unrestricted ... -
Studies on Sasakian, Lorentzian para (LP)-Sasakian manifold and other related manifolds
(School of Mathematics, University of Nairobi, 2007)The study of tensors in differentiable manifolds that vary in structure have attracted many researchers. In this thesis out of many newly defined tensors W2 -curvature tensor and W4 -curvature tensor have been studied ... -
Statistical assessment of health and sustainability indicators of an agroecosystem
(School of Mathematics, University of Nairobi, 2002)The health and well-being of individuals within agricultural communities depends on a number of biophysical, economic and social factors, all of which are highly interconnected, making simple disciplinary approaches ... -
The biology and fishery of plectorhinchus flavomaculatus. (Pisces: Haemulidae) from Mpunguti marine reserve.
(School of Biological Sciences, University of Nairobi, 2002)This study describes the reproductive biology and fishery of Plectorhinchus flavomaculatus during the Northeast and Southeast monsoon within the Kenyan inshore marine waters. The study covers the period from January to ... -
Maintainability of structures in a graded manpower system by wastage control
(School of Mathematics, University of Nairobi, 2008)So far a lot of studies have been done on the effects of transition probabilities on the changing manpower structures. In particular, the study is simplified when the transition process has stabilized, in which case we ... -
