Fuzzy Modeling for the Dynamics of Alcohol-Related Health Risks with Changing Behaviors via Cultural Beliefs
Mayengo, Maranya; Kgosimore, Moatlhodi; Chakraverty, Snehashish (Hindawi, 2020-07-13)In this paper, we propose and analyze a fuzzy model for the health risk challenges associated with alcoholism. The fuzziness gets into the system by assuming uncertainty condition in the measure of influence of the risky ... -
Fuzzy modelling on the depletion of forest biomass and forest-dependent wildlife population
Fanuel, Ibrahim; Mirau, Silas; Mayengo, Maranya; Moyo, Francis (Elsevier, 2023-09)This paper presents a system of non-linear differential equations describing the depletion of forest biomass and forest-dependent wildlife population caused by human population and its associated activities. The model ... -
Mathematical modeling and extraction of parameters of solar photovoltaic module based on modified Newton–Raphson method
Mayengo, Maranya; Mlazi, Nsulwa; Geminpeter, Lyakurwa; Kichonge, Baraka (Elsevier, 2024-01-17)This paper presents a numerical method for estimating four physical parameters of a single-diode circuit model based on manufacturer’s datasheet. A system of four non-linear equations are formed based on three key points ... -
Mathematical modeling of vehicle carbon dioxide emissions
Mayengo, Maranya; Donald, Pita; Lambura, Aristide (Cell Press, 2024-01-02)The demand for transportation, driven by an increasing global population, is continuously rising. This has led to a higher number of vehicles on the road and an increased reliance on fossil fuels. Consequently, the rise ... -
Mathematical models for the dynamics of health related risks associated with alcoholism and its control strategy in Tanzania
Mayengo, Maranya (NM-AIST, 2021-08)Alcoholic behavior has continually posed health challenges in many communities for decades. Referring to Tanzanian situation, this study presents a more realistic model for the dynamics of health risks associated with ... -
Modeling the dynamics of Diamondback Moth infestations on cabbage biomass
Paul, Daniel; Mayengo, Maranya; Daudi, Salamida (ELSEVIER, 2023-01-01)The Diamondback Moth (Plutella xylostella) is a notorious agricultural pest that poses significant challenges to cabbage production. In this study, we formulated and analyzed the deterministic differential equations to ... -
Parameters estimation, global sensitivity analysis and model fitting for the dynamics of Plutella xylostella infestations in a cabbage biomass
Mayengo, Maranya; Daniel, Paul; Salamida, Daudi (Elsevier, 2024-01-24)Plutella xylostella, commonly called Diamondback moth (DBM), a highly destructive and rapidly spreading agricultural pest originally from Europe. This pest poses a significant threat to global food security, with ... -
Predatory effects on the dynamics of Spodoptera Frugiperda infestations in maize
Reuben, Yusuph; Mayengo, Maranya; Daudi, Salamida (ELSEVIER, 2023)Maize remains in demand due to its nutritive value, capacity to provide food for a growing world population, contribution to food security, and increase in worldwide investments in ethanol as a biofuel. However, the invasion ... -
The role of asymptomatic carriers on the dynamics of a lymphatic filariasis model incorporating control strategies
Stephano, Mussa; Mayengo, Maranya; Irunde, Jacob (ELSEVIER, 2024-05-03)This study presents a mathematical model to investigate the patterns of transmission in lymphatic filariasis. The model considers chronic, acute, and asymptomatic individuals and integrates key control strategies. Random ... -
Sensitivity analysis and parameters estimation for the transmission of lymphatic filariasis
. Stephano, Mussa; Mayengo, Maranya; Irunde, Jacob; Kuznetsov, Dmitry (Heliyon, 2023-05-16)Lymphatic filariasis is a neglected tropical disease which poses public health concern and socio- economic challenges in developing and low-income countries. In this paper, we formulate a deterministic mathematical model ... -
The Volterra–Lyapunov matrix theory for global stability analysis of alcohol-related health risks model
Mayengo, Maranya (Elsevier, 2023-01)This paper studies the global stability analysis of a modified framework proposed by Mayengo et al. on alcohol-related health risks model. We first present the global stability analysis of risk-free equilibrium (RFE). ...
