Magnetohydrodynamic Free Convention Flow of a Heat Generating Fluid Past a Semi-Infinite Vertical Porous Plate With Variable Suction

Musyoki, Ishmail (2013-02-26)

In this study, a magnetohydrodynamic convection flow of an electrically conducting heat generating fluid past a semi-infinite vertical porous plate with variable suction is considered. The fluid flow is unsteady and a ...
Maize Disease Classification Model Based Multi Task Learning - Convolutional Neural Networks

Niyomwungere, Diane (JKUAT-COPAS, 2024-02-05)

One of the top machine learning algorithms for image classification is Convolutional Neural Networks, according to experts. Convolutional Neural Networks has been extensively used in the agriculture sector for a variety ...
Major genome region underlying artemisinin resistance in malaria parasite isolates from Kisumu County, Western Kenya.

Ngalah, Bidii Stephen (2015-06-20)

Clinical resistance to artemisinin and its derivatives is now well established in Southeast Asian (SEA). Studies from SEA have identified single nucleotide polymorphisms (SNPs) which are significantly associated with delayed ...
A METHOD FOR SOFTWARE MAINTENANCE RISK ASSESSMENT AT ARCHITECTURE LEVEL DESIGN

TOMBE, RONALD KENG’ARA (2015-06-22)

Software projects are difficult to manage and too many of them end in failure. One explanation for the high failure rate is that managers are not taking prudent measures to assess and manage the risks involved in these ...
A Metrics-based Framework for Measuring the Reusability of Object-oriented Software Components

Nyasente, Sammy Olive (2015-06-22)

Software reuse is a popular way of addressing software development issues—such as high cost of development, low productivity and poor quality. However, organizations are yet to realize maximum payoff from reuse due to ...

Nyasente, Sammy Olive (2015-06-22)

Software reuse is a popular way of addressing software development issues—such as high cost of development, low productivity and poor quality. However, organizations are yet to realize maximum payoff from reuse due to ...
Mhd turbulent flow in presence of inclined magnetic field past a rotating semi-infinite plate

Maswai, Rency Chebet (2015)

A turbulent incompressible fluid flow past a semi-infinite vertical rotating plate has been investigated, the flow considered is in the presence of a strong inclined constant magnetic field. An induced electric current ...
Microbial Diversity and Community Structure within Equatorial Lakes Olbolosat and Oloiden in Kenya

Kiama, Catherine Wachera (JKUAT-COPAS, 2022-11-01)

Lakes Olbolosat and Oloiden which lies along the equator are economically and ecologically important ecosystems due to their high productivity and nutrient recycling capacities. Microbes are important in the functioning ...
Microbial Diversity of Lake Elmenteita, Kenya

Kachiuru, Romano Mwirichi (2013-02-22)

The major goal of microbial ecology is to understand microbial diversity in natural habitats their interaction with one another and with their habitat. The soda lakes are highly productive environments and the soda lakes ...
Milk Quality Assessment for Adulteration and Organic Contaminants in Juja and Githurai Markets, Kiambu County

Ouma, Josephine Adhiambo (JKUAT-COPAS, 2023-08-08)

The annual milk consumption rate in Kenya is estimated at 50-150 liters per capita. Approximately 70% of milk marketed in Kenya is sold through a largely unregulated informal market. There are concerns about the quality ...
Modeling and Analysis of Wax Deposition from Multiphase Flow in Field-Scale Crude Oil Pipeline Transport Systems

Ochieng, Francis Oketch (JKUAT-COPAS, 2024-06-18)

The formation of solid wax crystals that interlock and form a gel-like layer on the inner wall of the pipeline greatly influences the transportation of waxy crude oil through pipeline systems. The deposited layer grows ...
Modeling and Simulation of Vibrations of a Tractor Gearbox

Kimotho, James Kuria (2013-05-15)

The vibration characteristics of a four-stage reduction tractor gearbox were studied. These characteristics are: displacement amplitudes, natural frequencies and mode shapes. The main aim of the study was to obtain ...
Modeling electricity demand and fuel prices using nonparametric methods and extreme value theory

Mbugua, Levi Ng’ang’a (2014-07-02)

Consumer behaviour towards different forms of utility varies over time. The variation can be so large that the estimated relationship between the response variable and its associated explanatory variables is seriously ...
Modeling fluid flow in open channel with circular cross – section

Tsombe, Daddy Peter (2013-02-26)

Flow in a closed conduit is regarded as open channel flow, if it has a free surface. This study considers unsteady non-uniform open channel flow in a closed conduit with circular cross-section. We investigate the effects ...
Modeling the Solar Forcing of the Total Column Ozone Variation in Selected Cities in Kenya

Songa, Carolyne May Mutambi (COPAS, JKUAT, 2017-06-05)

A quantitative non- experimental correlation study aimed at investigating the relationship between ozone and the solar activity indices for the period 1985- 2011 was carried out. Dataset for solar activity indices were ...
Modeling Traffic Flow on Multi-Lane Road: Effects of Lane-Change Manoeuvre Due to Ramps and Weaving Sections

Ndungu, William Kuria (JKUAT-COPAS, 2022-05-12)
