Reaction invariants and their importance in the analysis of eigenvectors, state observability and controllability of the continuous stirred tank reactor
(University of Nairobi, 1974-09)Two different projection operators are found, projecting the state space of a continuous stirred tank reactor (C.S.T.R.) dynamic model on the space of asymptotically invariant states (or on the space of true invariant ... -
Non-destructive XRF analysis of Nigerian and Kenyan clays
(University of Nairobi, 1997-04)Nigerian and Kenyan clays were analysed using energy dispersive X-ray fluorescence (EDXRF) technique and thirteen elements (Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Zr, Nb and Pb) were detected. The health implications, ... -
The Prospects Of Enhanced Space Science Training In Kenya
(University of Nairobi, 1997)To a limited extent, space exploration has been conducted in Kenya for almost the last two decades through a joint project (San Marco Project) between the Government of Kenya and the Government of Italy. Other space science ... -
Space science education in the African continent
(University of Nairobi, 1997)Through measurement and interpretation of the spectral, spatial and temporal variations in electromagnetic emissions and reflections from the Earth's surface, important information related to natural resources can be ... -
Characterization and transport of aerosols over equatorial eastern Africa
(University of Nairobi, 2001-09)Measurements of the composition of aerosol partitioned into two size fractions, fine (particle aerodynamic equivalent diameter, dp <= 2.5 mum) and coarse (2.5 < dp <= 10 mum) were made at a high-altitude site over equatorial ... -
Between Global and Regional Visions: The Way Forward for Uganda’s Cities
(university of Nairobi, 2013)Cities have a significant impact on the economy and development of any given nation. In particular, they offer a place to live. They have proved to be dense networks of interchanging investments, information, goods and ... -
Variations in Land Delivery Costs as a Factor in Land Speculation in Metr opolitan Nairobi: A case study of Eastlands, Nairobi, and the bordering areas of Machakos and Kajiado counties
(University of Nairobi, 2013)The urban rural duality in the land administration policy in Kenya tends to create two land use development control models and, further, such policy results in two separate land transaction costs. In a situation where land ... -
Partial Replacement Of Natural River Sand With Crushed Rock Sand In Concrete Production
(University of Nairobi,, 2013)The use of crushed rock sand as a partial replacement of river sand in concrete production was investigated. Water cement ratio varied between 0.55 and 0.59 for 0 % to 100 % natural sand replacement. The slump ranged ... -
Micromechanisms of short fatigue crack growth in an Al-Si piston alloy
(University of Nairobi, 2014-06)The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue ... -
Environmental Impact Assessment in Kenya
(University of Nairobi, 2013)In Kenya, environmental impact assessment (EIA) has been used to ensure that environmental management is integrated into project planning and decision-making with a view of achieving ecologically sustainable development. ... -
The production of artisanal dimension stone in Nairobi: A factor analytic study
(University of Nairobi, 2013)The study looked at the opportunities and constraints facing artisanal units involved in the production of dimension stone. Twenty-seven observable variables were derived from literature and developed into a questionnaire ... -
Application of artisanal dimension stone in the building industry: factor analysis of the regulatory environment in Nairobi, Kenya
(University of Nairobi, 2014)This is an assessment of the regulatory environment in which artisans operate to produce dimension stone in Nairobi where the quarrying of the same becomes an aspect of artisanal mining; an activity that is fraught with ... -
University–industry partnership for effective industrialization: a framework for Ngumzo
(University of Nairobi, 2002)A conceptual framework for partnerships between University and Industry emphasizing the need for Ngumzo (i.e. dialogue with harmony) is presented. This framework is based on the model of a microprocessor. Inputs that ... -
On the Performance of Video Band Complex Correlators
(University of Nairobi, 1983-05-19)The performance data for various correlation schemes for Gaussian signals converted from the intermediate frequency band to the video band are derived and discussed. The folded-band conversion scheme is shown to have ... -
Correlation Systems In Radio Astronomy And Related Fields
(University of Nairobi, 1984-02)A comprehensive review of the theory and practice of analogue and digital correlation systems used in radio astronomy and its related fields is given. The correlators are discussed according to the following classifications: ... -
Long baseline determination using observations with macrometer II prototype receivers.
(University of Nairobi, 1987) -
Rectangular-Wave Modulation
(University of Nairobi, 1983-03)Rectangular-wave modulated pulse lengths are expressed as a function of the modulation index. The theoretical expressions are experimentally verified. An experimental measurement of signal-to-noise ratio for rectangular-wave ... -
Error Patterns In Correlators With Four-Level Quantisation
(University of Nairobi, 1984-02)In the evaluation of the analogue correlation from the digital correlation of coarsely quantised Gaussian signals, it is necessary to know the threshold levels used in the quantisation. The formulas used in the evaluation ...
