    Peter Ochieng; Waweru Mwangi (Journal of Computer Science & Systems Biology, 2014)
    Software sizing is a crucial activity among the task of software management. Work planning and subsequent estimation of effort required is based on the estimate of the software size required. Software developers are ...
  • Spatial mapping of the extents and volumes of solid mine waste at Samrudha Resources Mine, Kenya: a GIS and remote sensing approach 
    Francis, Gitau; Justin, Kambale Maghanga; Mary, Nelima Ondiaka (Modeling Earth Systems and Environment, 2021-05-18)
    Monitoring and estimating solid mine waste produced during mining operations at a spatial–temporal scale plays a fundamental role in waste management and mitigation of environmental impacts. Iron ore mining and processing ...
  • Statistical Models for Count Data 
    Kasyoki Muoka, Alexander; Owino Ngesa, Oscar; Gichuhi Waititu, Anthony (Science Journal of Applied Mathematics and Statistics, 2016)
    Statistical analyses involving count data may take several forms depending on the context of use, that is; simple counts such as the number of plants in a particular field and categorical data in which counts represent ...
  • A Study of Solutions to Euler Equations for a One Dimensional Unsteady Flow 
    Mutua, S. K.; Kimathi, M. E.; Kiogora, P. R.; Mutua, N. M. (American Journal of Computational and Applied Mathematics, 2013)
    In this paper we deal with the Euler equations for Isothermal gas. In analyzing the equations we obtain two real and distinct eigenvalues which enables us to determine the wave structure of the possible solutions to the ...
