Mathematical Analysis of Two Competing Cancer Cell Migration Mechanisms Driven by Interstitial Fluid Flow
Evje, Steinar; Winkler, Michael (Peer reviewed; Journal article, 2020-04)Recent experimental work has revealed that interstitial fluid flow can mobilize two types of tumor cell migration mechanisms. One is a chemotactic-driven mechanism where chemokine (chemical component) bounded to the ... -
Mathematical and Numerical Aspects of Scalar Nonlinear Conservation Laws
Bhatti, Farrukh Abbas (Master thesis, 2023)This thesis delves deeply into numerical solutions to nonlinear conservation laws. It focuses largely on the Method of Characteristics, its application in solving conservation laws, and the implementation of solutions in ... -
Mathematical and Numerical Modelling of Lithium Battery
Bandara, Yasas (Master thesis, 2021)Application of lithium-ion batteries have increased in recent years due to their high energy density, low weight and smaller form factor. Machine learning algorithms are used in lithium-ion battery management systems due ... -
Mathematical modeling of cancer cell migration - from in vitro to in vivo
Waldeland, Jahn Otto (PhD thesis UiS;511, Doctoral thesis, 2020-05)Tumors has been the object of computational model studies for nearly five decades. The early models considered simple tumor growth based on nutrients, whereas models now can simulate from microscale gene expressions in ... -
Numerical treatment of two-phase flow in capillary heterogeneous porous media by finite-volume approximations
Evje, Steinar; Friis, Helmer André (Journal article; Peer reviewed, 2012)This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, ... -
On the numerical discretization of a tumor progression model driven by competing migration mechanisms
Qiao, Yangyang; Li, Qing; Evje, Steinar (Peer reviewed; Journal article, 2021)In this work we explore a recently proposed biphasic cell-fluid chemotaxis-Stokes model which is able to represent two competing cancer cell migration mechanisms reported from experimental studies. Both mechanisms depend ... -
Ostwald ripening of trapped gas bubbles in porous media : A pore-scale perspective
Singh, Deepak (PhD thesis UiS;747, Doctoral thesis, 2024)Ostwald ripening of gas bubbles is a thermodynamic process for mass transfer, which is significant for both foam-enhanced oil recovery and underground gas storage. During recovery, it can impact the macroscopic efficiency. ... -
Tumor Interstitial Fluid Pressure Distribution – Analytical and Numerical Study
Rasouli, Seyedeh Shahrzad (Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017)Cancer is one of the deadliest diseases in the world and although huge research efforts have been applied to improve survival rates, there are still great challenges in treatment of the disease. Many factors contribute in ... -
Two-Dimensional Fluid Flow in Heterogeneous Porous Media Using Finite Analytic Method
Aqrawi, Abdul-Razzaq (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)This study started by exploring the different discretization methods that have been explored and developed throughout the years for reservoir simulators. Understanding simulators in general and how they are used in the oil ... -
Weak solutions for a gas liquid model relevant for describing gas-kick in oil wells
Evje, Steinar (Journal article; Peer reviewed, 2011)The purpose of this paper is to establish a local in time existence result for a compressible gas-liquid model. The model is a drift-flux model which is composed of two continuity equations and one mixture momentum equation ...
