Noncompact Equilibrium Points for Set-Valued Maps

open access: yesAbstract and Applied Analysis, 2014
We prove a generalized result on the existence of equilibria for a monotone set-valued map defined on noncompact domain and take its values in an order of topological vector space. As consequence, we give a new variational inequality.

Reference-Dependent Stochastic User Equilibrium with Endogenous Reference Points

open access: yesEuropean Journal of Transport and Infrastructure Research, 2013
We consider the application of reference-dependent consumer choice theory to traffic assignment on transportation networks. Route choice is modelled based on random utility maximisation with systematic utility embodying loss aversion for the travel time ...

Modelling and analysis of HIV‐TB co‐infection in a variable size population

open access: yesMathematical Modelling and Analysis, 2005
In this paper, a nonlinear mathematical model is proposed for the transmission dynamics of HIV and a curable TB pathogen within a population of varying size.

On the complexities of modeling HIV/AIDS in Southern Africa

open access: yesMathematical Modelling and Analysis, 2008
In this paper problems associated with the modeling of HIV/AIDS in Southern Africa are presented. A mathematical model is presented to highlight the three major challenges of modeling HIV/AIDS, i.e condom use, vertical transmission and treatment.

Is the forest biomass a key regulator of global warming?: A mathematical modelling study

open access: yesGeology, Ecology, and Landscapes, 2022
In this article, a mathematical model has been formulated by considering forest biomass and global warming as a separate compartment. It is assumed that the forest biomass follow logistic growth in the absence of global warming.

Some Dynamic Aspects of a Sextic Galactic Potential in a Rotating Reference Frame

open access: yesApplied Sciences, 2023
This work aims to explore some dynamic aspects of the problem of star motion that is impacted by the rotation of the galaxy, which we model as a bisymmetric potential based on a two-dimensional harmonic oscillator with sextic perturbations.

Realization of the Triple Points of Equilibrium Hydrogen and Equilibrium Deuterium

open access: yesTransactions of the Society of Instrument and Control Engineers, 2002
The triple points of equilibrium hydrogen and equilibrium deuterium have been realized using a calorimetric method and sealed cells, which include hydrogen (or deuterium) and a catalyst for the ortho-para equilibration. Anomalous increases on heat capacity curves of each substance, which markedly disturb melting curves of the triple point, are observed

Homotopy Perturbation Method for Pneumonia–HIV Co-Infection

open access: yesFoundations, 2022
It is well known that HIV (human immunodeficiency virus) weakens the immune system of individuals, resulting in risk of other infections, such as pneumonia. The most frequent viral pneumonia seen in individuals infected with HIV is cytomegalovirus (CMV).

Modeling and Analyzing Homogeneous Tumor Growth under Virotherapy

open access: yesMathematics, 2023
We present a mathematical model based on ordinary differential equations to investigate the spatially homogeneous state of tumor growth under virotherapy.
