    • The effect of a difference in angle in two lateral inflow channels on the main channel's velocity 

      Chirchir, A. C.; Kandie, J. K.; Maremwa, J. S. (International Journal of Statistics and Applied Mathematics, 2021-04)
      In this study, we examined the flow from two lateral inflow channels in a man-made open rectangular channel of an incompressible Newtonian fluid. The influences of the angles as it varies directly proportional to each ...

    • EFFECT OF VACCINATION ON MATHEMATICAL MODELING OF COVID-19 

      Jerop, Rael; Julius, Maremwa S.; Kandie, Joseph K. (International Journal of Science Academic Research, 2023-02)
      Corona virus 2019 (Covid-19) have been endemic both in Africa and the whole world. In this paper we have formulated and analyze mathematical model of covid-19 that monitors the temporal dynamics of the disease in the ...

    • Exploration of D-, A-, I- and G- Optimality Criteria in Mixture Modeling 

      Wanyonyi, Samson W.; Okango, Ayubu A.; Koech, Julius K. (Asian Journal of Probability and Statistics, 2021-05)
      A design optimality criterion, such as D-, A-, I-, and G- optimality criteria, is often used to analyze, evaluate and compare different designs options in mixture modeling test. A mixture test is an experiment where ...

    • Mathematical modeling of flow of fertilizer-water mixture through soil and its effect on concentration and plant growth 

      Rutto, Kipkorir Timothy; Maremwa, Julius Shichikha; Kandie, Joseph Kipchirchir (International Journal of Statistics and Applied Mathematics, 2021)
      In this research we aim to demonstrate and explore how mathematical modeling can be used to aid people gain knowledge and understanding of plants and, in particular, interactions between plants, fertilizers, soil, and ...

    • Modeling Key Drivers of Under-Five Child Malnutrition in Marsabit County, Kenya: Application of the Logit Model 

      Rop, Benjamin Kiptoo; Koech, J.; Otieno, A. (Asian Journal of Probability and Statistics, 2021-04)
      Malnutrition remains one of the major problems in developing countries affecting both adults and children under 5 years. The use of binary logistic regression model was employed, and parameters of interest estimated. ...

    • Need to make people believe science-science is reliable and means truth 

      Wangui, Patrick (Open Journal of Social Science,, 2019)
      Science is the engine that drives the wheel of development. Consequently, there is a need for people to have faith in science and believe its facts and truths. This paper has looked into ...

    • ON THE NORM OF AN ELEMENTARY OPERATOR OF FINITE LENGTH IN A 𝑪∗ALGEBRA 

      Kawira, Esther; King'ang'i, Dennis, N.; Musundi, Sammy, W. (Journal of Progressive Research in Mathematics(JPRM), 2018)
      Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operatorsof different lengths using different approaches. ...

    • On the Norm of Basic Elementary Operator in a Tensor Product 

      Muiruri, Peter; King'ang'i, Denis; Musundi, Sammy (International Journal of Scientific and Innovative Mathematical Research., 2019)
      In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ...

    • On Unitary Invariance of Some Classes of Operators in Hilbert Spaces 

      Muhati, Linety N.; Khalagai, J. M. (Pure Mathematical Sciences, 2020)
      It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However, under the stronger relation of unitary equivalence ...

    • Optimal Kiefer Ordering of Simplex Designs for Third-Degree Mixture Kronecker-Models with three ingredients. 

      Korir, Betty (Mathematical Theory and Modeling, 2019)
      This paper investigates the Kiefer optimality in the third-degree Kronecker model for mixture experiments. For mixture models on the simplex, a better design is obtained, by matrix majorization that yields a larger ...

    • Optimization of Split-Plot Design in the Context of Mixture Process Variable Settings 

      Wanyonyi, Samson W.; et al. (Asian Journal of Probability and Statistics, 2021-04)
      In the presence of process variables, a mixture design has become well-known in statistical modeling due to its utility in modeling the blending surface, which empirically predicts any mixture's response and serves as the ...

    • Parametric Interval Estimation of the Geeta Distribution 

      Kinyanjui, Josphat; Korir, Betty (International Journal of Statistics and Probability, 2018)
      t is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained ...

    • Parametric Point Estimation of the Geeta Distribution 

      Korir, Betty (International Journal of Statistical Distributions and Applications, 2018)
      Geeta distribution is a new discrete random variable distribution defined over all the positive integers with two parameters. This distribution belongs to the family of Location-parameter (LDPD) system and is of the form ...
