Winstanley, H.F.; Chapwanya, Michael; Fowler, Andrew Cadle, 1953-; O’Brien, S.B.G.
(Springer, 2015-09)
We present a model of biofilm growth in a long channel where the biomass is assumed
to have the rheology of a viscous polymer solution. We examine the competition
between growth and erosion-like surface detachment due ...

Ntumba, Patrice P.; Anyaegbunam, Adaeze Christiana
(Springer, 2011)
Building on prior joint work by Mallios and Ntumba, we study
transvections (J. Dieudonn´e), a theme already important from the classical
theory, in the realm of Abstract Geometric Algebra, referring herewith
to symplectic ...

Yani, Bridgette; Harding, Ansie; Engelbrecht, Johann
(Taylor and Francis, 2019)
This paper focuses on the students who are registered in the University of Pretoria’s academic development programme, named the Four-year Programme (FYP). The programme was introduced as a gateway for students who are ...

(Elsevier, 2023-03)
Time-dependent partial differential equations of parabolic type are known to have a lot of applications in biology, mechanics, epidemiology and control processes. Despite the usefulness of this class of differential ...

Raftery, James G.
(Duke University Press, 2016)
This paper provides a semantic analysis of admissible rules
and associated completeness conditions for arbitrary deductive systems,
using the framework of abstract algebraic logic. Algebraizability is not
assumed, so ...

Chapwanya, Michael; Lubuma, Jean M.-S.; Terefe, Yibeltal Adane
(Springer, 2016-09)
Rabies is a fatal disease in dogs as well as in humans. A possible model to represent
rabies transmission dynamics in human and dog populations is presented. The next
generation matrix operator is used to determine the ...

Karaagac, Berat; Owolabi, Kolade M.; Pindza, Edson
(Elsevier, 2022-09)
In this manuscript, the fractional-in-time NoyesField model for Belousov-Zhabotinsky re- action transport is considered with a novel numerical technique, which was used to ap- proximate the Atangana-Baleanu (ABC) operator ...

Banasiak, Jacek; Joel, L.O.; Shindin, S.
(Wiley, 2018-11)
Fragmentation‐coagulation processes, in which aggregates can break up or get together, often occur together with decay processes in which the components can be removed from the aggregates by a chemical reaction, evaporation, ...

Djoko, J.K. (Jules Kamdem); Lubuma, Jean M.-S.
(Springer, 2016-12)
This work is concerned with the time discrete analysis of the Oseen system of equations driven by nonlinear slip
boundary conditions of friction type. We study the existence of solutions of the time discrete model and ...

Appadu, A. Rao; Djoko, J.K. (Jules Kamdem); Gidey, H.H.; Lubuma, Jean M.-S.
(Springer, 2017-04)
In this work, four finite volume methods have been constructed to solve the
2D convective Cahn–Hilliard equation with specified initial condition and periodic
boundary conditions. We prove existence and uniqueness of ...

Combrinck, M.
(Elsevier, 2009)
The S-layer differential transform produces subsurface conductivity-depth images from Time Domain Electromagnetic (TDEM) data. It is a very fast method, but suffers from high noise levels due to the implementation of two ...

Djoko, J.K. (Jules Kamdem); Razafimandimby, Paul Andre
(Taylor and Francis, 2014)
In this work, we study Brinkman-Forchheimer equations driven under slip boundery conditions of friction type. We prove the existence and uniqueness of weak solutions by means of regularization combined with the Faedo-Galerkin ...

Chapwanya, Michael; Lubuma, Jean M.-S.; Terefe, Yibeltal; Tsanou, Berge
(Springer, 2022-10)
The tenth Ebola outbreak in the Democratic Republic of Congo (DRC) that occurred from 2018 to 2020 was exacerbated by long-lasting conflicts and war in the region. We propose a deterministic model to investigate the impact ...

Banasiak, Jacek
(Springer, 2019-01)
In the paper we present a survey of recent results obtained by the author that concern discrete fragmentation–coagulation models with growth. Models like that are particularly important in mathematical biology and ecology ...

Kikianty, Eder; Sinnamon, Gord
(Elsevier, 2017-10)
Angular equivalence is introduced and shown to be an equivalence relation among the norms on a fixed real vector space. It is a finer notion than the usual (topological) notion of norm equivalence. Angularly equivalent ...

Asset Liability Management (ALM) is an essential risk management technique in Quantitative Finance and
Actuarial Science. It aims to maximise a risk-taker’s ability to fulfil future liabilities. ALM is especially critical
in ...
