Fitting a Markovian Queuing Model to Bus Park Revenue Collection Point in Kisii Town, Kenya
(International Journal of Statistics and Applied Mathematics, 2019)In queuing theory one deals with the mathematical analysis of the performance of queuing systems. In our daily lives customers encounter queues while seeking services in institutions. The increase in the number of customers ... -
Fixed Points Approximation for Non Expansive Operators in Hilbert Spaces
(Int. J. Open Problems Compt. Math, 2/2/2021)Approximations of fixed points have been done in different space and classes. However, characterizations in norm attainable classes remain interesting. This paper discusses approximation of nonexpansive operators in Hilbert ... -
Forecasting Monthly Sugar Cane Yields Using Box-Jenkin’s Predictive Models in Kenya
(International Journal of Statistics and Applied Mathematics, 2019-10-24)Sugarcane is the main raw material in the production of sugar in Kenya. The supply of sugarcane affects directly the quantity of sugar supplied in the markets. Low supply of sugarcane leads to a decline in the amount of ... -
Forensic estimation of time of death: A mathematical model
(International Journal of Management, IT and Engineering, 2013-07)In this paper we establish the exact time of death of a murdered person. This leads to an ordinary differential equation whose solution has been analyzed to provide the approximate time of death. Forensic expert will try ... -
Formulating Black Scholes Equation Using a Jump Diffusion Heston’s Model
(International Journal of Statistics and Applied Mathematics, 12/7/2021)In modern financial mathematics, accurate values are obtained by taking into account a considerable number of more realistic assumptions in logistic Black Scholes equation. The aspects considered here are cost of transactions ... -
Formulation of a Four-Species Food Web System with Prey Refuge and Holling Type III Functional Response
(World Wide Journal of Multidisciplinary Research and Development, 2023-01)The coexistence of interacting biological species is a vital issue for the management of existing resources and the prediction of the long-term survival of each species. Many species become extinct due to several factors ... -
