Game Theoretic Multi-Agent Systems Scheduler for Parallel Machines
(School of Computing and InformaticsSchool of Computing and Informatics, 2008)This paper considers the scheduling of n independent jobs on m non-identical machines using the ideas from game theory and multi-agent systems. The values of n and m are fixed at 30 and 6 respectively giving a schedule ... -
Dynamic Resource Allocation: A comparison of First Price Sealed Bid and Vickrey Auctions
(School of Computing and Informatics, 2008)Resource allocation involves assigning the resources to the resource users. Where the resources and the resource users do not change with time, the resource allocation problem can be solved as a scheduling problem. Where ... -
Towards an Education Evaluation Framework: Synchronous and Asynchronous E-Learning Cases
(Research Centre for Education and TechnologySchool of Computing and Informatics, 2006)Information and Communications Technologies (ICTs) are the computing and communications facilities and features that variously support teaching, learning, and a range of activities in education. It has always been assumed ... -
Using Adaptive Link Hiding to Provide Learners with Additional Learning Materials in a Web-Based System
(Research Center for Educational TechnologySchool of Computing and Informatics, 2012)This article reports results from a web-based online learning experiment that provided learning support to students in an object-oriented programming course. This support was intended to assist learners in acquiring ... -
Comparison of Different Machine Learning Algorithms for the Initialization of Student Knowledge Level in a Learner Model-Based Adaptive E-Learning System
(Faculty of Psychology and Educational Sciences, Free University of BrusselsSchool of Computing and Informatics, 2009)Web-based learning systems give students the freedom to determine what to study based on each individual student’s learning goals. These systems support students in constructing their own knowledge for solving problems ... -
A Grid Service Matrix Model for Resource Scheduling in Grid Computing Environments
(School of Computing and Informatics, 2007)A grid computer consists of shared computing resources that are presented to the user as a single powerful computing facility. The shared computing resources have independent autonomous ownership. The vision in grid ... -
The poor and the mobile phone related spending
(School of Computing and Informatics, 2011)In this paper, we present work done to find out the challenges poor people in Kakamega east district in western Kenya face to maintain their mobile phones. It reports on findings from a study conducted to find out how the ... -
Agent-based Scheduler for Unrelated Parallel Machines using a load balancing heuristic
(School of Computing and Informatics, 2009)The problem of finding an optimal schedule for n independent jobs on m non-identical machines is considered. Several solutions to this problem have been proposed but most of them do not scale well due to the large ... -
Estimation of Radiative Forcing due to Aerosols over Selected Sites in Kenya
(Meteorology, 2011)Atmospheric aerosols modulate the radiative budget and ambient air quality of the atmosphere, thus, there is a need to develop both analytical and computational methodological techniques that determine their physical, ... -
Utilization of meteorological products in agriculture and water sectors in Central and Eastern Kenya
(Meteorology, 2003)A survey, through a questionnaire, of the level of awareness of weather products, reliability, relevance, actual usage and economic implications of usage in Kenya is performed. Interviews were conducted on employees of ... -
Equatorial total ozone as a predictor of sea surface temperatures useful for East African seasonal rainfall prediction
(Meteorology, 2003)Monthly total ozone data for the period 1979 to 2001, obtained from Total Ozone Mapping Spectrophotometer (TOMS), for two equatorial African locations of Nairobi, Kenya and Mahe, Seychelles were correlated with monthly ... -
A simple model for determining the potential risks of lightning strokes over the cities of Nairobi and Mombasa
(Meteorology, 2003)This study examines the cloud to ground lightning discharges over the cities of Nairobi and Mombasa including their environs. Ground based and Satellite-derived meteorological data were utilized in this study and included ... -
Towards estimating surface ultraviolet irradiance using dobson ozone spectrophotometer observations
(Meteorology, 2003)A technique is developed to process Dobson Ozone (O3) Spectrophotometer’s raw data to produce UV-B irradiance values using the instrument's A, C, and D wavelength pairs, (305.5, 325.4), (311.5, 332.4) and (317.6, 339.8) ... -
The Relationship between Atmospheric Aerosols and Rainfall over the Three Cities in Kenya
(University of Nairobi, Department of MeteorologyGeology, 2012)This study investigates the characteristics of absorbing and non-absorbing aerosols over Nairobi, Kenya and how they relate to the rainfall over the three cities in the Republic of Kenya. The data set used in the study ... -
Influence of Climate on Tea Yields in Mount Kenya Region
(University of Nairobi, Department of MeteorologyGeology, 2009)This study investigated the existence of a systematic relationship between tea yields and climatic parameters in the tea growing areas of Mount Kenya region. Both linear and multiple regression models were applied. ... -
Linkages between the Indian Ocean Dipole and East African Seasonal Rainfall Anomalies
(University of Nairobi, Department of MeteorologyGeology, 2008)This study was designed to understand the nature of the relationship between the Indian Ocean Dipole (IOD) index and seasonal rainfall in East Africa using statistical approaches. The statistical methods used in this ... -
Rainfall distribution over Nairobi area
(University of Nairobi, Department of MeteorologyMeteorology, 2007)The distribution of rainfall in time and space over Nairobi area is analysed for the 31-year base period between 1960 and 1990. The high-resolution limited-area numerical model, Geesthacht Simulation Model of the Atmosphere ... -
