On the performance, availability and energy consumption modelling of clustered IoT systems
(University of Nairobi, 2019)Wireless sensor networks (WSNs) form a large part of the ecosystem of the Internet of Things (IoT), hence they have numerous application domains with varying performance and availability requirements. Limited resources ... -
A Simplified Simulation Procedure and Analysis of a Photovoltaic Solar System Using a Single Diode Model
(University of Nairobi, 2020)A single diode model for a photovoltaic solar module is the most ideal and quick way of analyzing the module characteristics before implementing them in a solar plant. Solar modules manufacturers provide information for ... -
A Simplified Method for Parameter Determination of a Photovoltaic Module using Manufacturer’s data
(University of Nairobi, 2020)Accurate and fast modelling and simulation of Photovoltaic module requires careful determination and identification of the unknown parameters required in fitting the voltage-current and power-voltage curves to replicate ... -
Personal Cloud Computing Adoption: Integrating IT Mindfulness with TAM
(University of Nairobi, 2020)While extant literature is replete with studies on cloud computing adoption by organizations, there is a dearth of empirical literature on personal cloud computing adoption. This study aims at understanding how individuals ... -
Photocatalytic degradation of 4-chlorophenol by titanium dioxide: role of annealing temperature and morphology
(Journal of Applied Sciences and Environmental Management, 2020-01)This work investigates the degradation rate of 4-cholorophenol using Titanium dioxide photocatalysts. Chlorophenols and their compounds are a nuisance as they are recalcitrant to degradation in the environment. Three ... -
Water and the UN sustainable development goals
(University of Nairobi, 2022)Water is essential for life, but we need to balance human needs with those of the environment on which we depend for our wellbeing, our health and much of our wealth. Not all of us are lucky enough to have access to ... -
Conglomeratin: a New Antibacterial Flavonol Derivative From Macaranga Conglomerata Brenan (Euphorbiaceae)
(University of Nairobi, 2022)A new prenylated kaempferol, conglomeratin (1), alongside 7 known compounds including flavonoids (2 and 3), ellagic acid derivatives (4 and 5), triterpenoids (6 and 7), and a coumarin (8)were isolated from the leaves ... -
Influence of the pH of anthocyanins on the efficiency of dye sensitized solar cells
(University of Nairobi, 2022)The influence of the pH of anthocyanins on photovoltaic performance in dye-sensitized solar cells has been investigated. Anthocyanins were extracted from crushed leaf stocks of Manihot esculenta Crantz (Cassava plant) using ... -
Mathematical Competitions in Africa: Their Prevalence and Relevance to Students and Teachers
(University of Nairobi, 2022)Mathematical competitions feature in most developed countries as a part of the secondary school experience, but to a lesser extent in developing countries. In this paper we investigate how widespread these competitions are ...
