Vulnerability of Nyabarongo River Water Abstraction to Climate Change in Rwanda
(International Journal of Environmental Sciences, 2023-02-13)
Purpose: Climate change in Rwanda is a great challenge resulting from increased temperature and causing abnormal variability in weather variables and threatening the socio-economic welfare of human beings. Water resources ...
Estimation of Population Mean Using Three-Stage Optional RRT Model in the Presence of Measurement Errors under Stratified Two-Phase Sampling
(2023)
In the present study, the problem of estimation of the finite population mean of a sensitive study variable using the three-stage optional Randomized Response Technique (RRT) model under measurement errors is addressed. A ...
Socio-Cultural Practices on the Use of Beetle Grubs as Food and Feed in Western Kenya
(Scientific Reports, 2023-05-13)
We examined the socio-cultural practices on the use of beetle grubs as food and feed in western Kenya by interviewing 211 randomly selected households and conducting seven focus group discussions in Bungoma, Kakamega, ...
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 ...
Numerical Analysis of Prey Refuge Effects on the Stability of Holling Type III Four-Species Predator Prey System
(Scientific Research Publishing, 2023-06-29)
The dynamic behavior of a multi-species system that includes a prey refuge and a Holling type III functional response is examined in this work. The pre-requisites for the presence of the equilibrium points, as well as their ...
Finite element approach to the solution of fourth order beam equation
(IJESM, 2013-06)
Finite element method is a class of mathematical tool which approximates solutions to initial and boundary value problems. Finite element, basic functions, stiffness matrices, systems of ordinary differential equations and ...
Derivation and solution of the heat equation in 1-D
(International Journal of Engineering, Science and Mathematics, 2013)
Heat flows in the direction of decreasing temperature, that is, from hot to cool. In this paper we derive the heat equation and consider the flow of heat along a metal rod. The rod allows us to consider the temperature, ...
The norm attainability of some elementary operators
(Applied Mathematics E-Notes, 2012)
Conditions for Positivity of Operators in Non-unital C*-algebras
(International Journal of Mathematical Analysis, 1/9/2015)
In this paper, we present results on the necessary and sufficient condi-tions for positivity of operators in non-unital C*- algebras
International Journal of Statistics and Applied Mathematics 2018; 3(4): 74-84 Reconstructing earth observation vegetation index records with a Bayesian spatiotemporal dynamic model
(International Journal of Statistics and Applied Mathematics, 2018-01)
Long-term vegetation index records derived from Earth observation facilitate the characterization of ecosystem response to climate variability and change. The presence of atmospheric components and radiometric inconsistencies ...
