On the Norm of Elementary Operator
(Advances in Pure Mathematics, 2014)The norm of an elementary operator has been studied by many mathematicians. Varied results have been established especially on the lower bound of this norm. Here, we attempt the same problem for finite dimensional operators -
EFFECT OF VACCINATION ON MATHEMATICAL MODELING OF COVID-19
(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 ... -
Detecting Remote Access Network Attacks Using Supervised Machine Learning Method
(MECS Press, 2023)Remote access technologies encrypt data to enforce policies and ensure protection. Attackers leverage such techniques to launch carefully crafted evasion attacks introducing malware and other unwanted traffic to the ... -
Application of ARIMA, and hybrid ARIMA Models in predicting and forecasting tuberculosis incidences among children in Homa Bay and Turkana Counties, Kenya
(PLOS DIGITAL HEALTH, 2023-02)Tuberculosis (TB) infections among children (below 15 years) is a growing concern, particularly in resource-limited settings. However, the TB burden among children is relatively unknown in Kenya where two-thirds of ... -
Mathematical modeling of flow of fertilizer-water mixture through soil and its effect on concentration and plant growth
(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 ... -
On Unitary Invariance of Some Classes of Operators in Hilbert Spaces
(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 ... -
Optimization of Split-Plot Design in the Context of Mixture Process Variable Settings
(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 ... -
Exploration of D-, A-, I- and G- Optimality Criteria in Mixture Modeling
(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 ... -
The effect of a difference in angle in two lateral inflow channels on the main channel's velocity
(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 ... -
Modeling Key Drivers of Under-Five Child Malnutrition in Marsabit County, Kenya: Application of the Logit Model
(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. ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(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 THE NORM OF AN ELEMENTARY OPERATOR OF FINITE LENGTH IN A 𝑪∗ALGEBRA
(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. ... -
The Acoustic Wave Propagation Equation: Discontinuous Galerkin Time Domain Solution Approach
(Applied Mathematical Sciences Vol. 13, 2019, no. 16, 753 - 767, 2019)This paper discusses a finite element method, discontinuous Galerkintime domain approach that solves the 2-D acoustic wave equation incylindrical coordinates. The method is based on discretization of thewave ... -
Construction of a Five-Level V-Dimensional Modified Third Order Rotatable Designs using a Pair of Pairwise Balanced Designs
(African Journal of Education, Science and Technology, 2019)Rotatable designs are devised for use of response surfaces. Rotatability is evidently a greatly popular property for Response Surface Methodology (RSM). RSM is a group of statistical and mathematical ... -
Need to make people believe science-science is reliable and means truth
(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 ... -
