Large Scale Invasion Of New Species And Of Genetic Information
The spatial dynamics of the invasion of new species and genetic dispersal is studied under the presumption of rising temperature by using a coherent approach of coupled partial differential equations of the reaction diffusion type. The nonlinear reaction terms model the population ... En savoir plus
Physical and FEM Simulation of Microprobe Insertion into Brain Tissue
In order to investigate the implantation of microprobes into brain tissue, we developed a finite-element and a physical model to replace real biological tissue for mechanical testing. Penetrating forces of a tungsten indenter into a layered structure was investigated with different ... En savoir plus
Simulation of the Spread of Epidemic Disease Using Persistent Surveillance Data
This paper proposes a novel data-mining framework to simulate the spread of epidemic diseases using persistent surveillance data. The framework is formulated by merging the persistent surveillance data about epidemics, geographic information and the dynamics of disease into a heat ... En savoir plus
On A Particle Tracking Technique To Predict Disinfection In Drinking Water Treatment Systems
Disinfection of drinking water is required to prevent the outbreak of water-borne diseases. Different treatment steps are available to disinfect the water, such as chlorination, ozonation or UV irradiation. The hydrodynamics of these processes play an important role in their performance. ... En savoir plus
Comparison of Finite Element and Monte Carlo Simulations for Inhomogeneous Advanced Breast Cancer Imaging
Three-dimensional FEM method provided by COMSOL is used to model an inhomogeneous advanced breast tumor of different optical properties for outer layer and inner core in a semi-infinite medium. The running time of FEM by COMSOL for one source and 14 detectors is 17.658s and which of ... En savoir plus
Multiphysics Modeling of Cellular Arrays Using Periodic Minimal Surfaces – A Drug and Gene Delivery Application
Minimal surfaces are found in nature from crystalline structures to biological nano and micro structures such as biomembranes, and osseous formations in sea urchin. An application to electrically mediated drug and gene delivery is presented. Periodic level surfaces which approximate ... En savoir plus
Numerical Investigation of a Time-dependent Magnetic Actuation Technique for Tagging Biomolecules with Magnetic Nanoparticles in a Microfluidic System
The magnetic body forces that act on mono-dispersed magnetic nanoparticles (MNPs) tagged biomolecules in a microfluidic system can be efficiently used in various applications that involve separation and detection including DNA and protein analysis, bio-defense, drug delivery, and ... En savoir plus
Modeling Bacterial Clearance Using Stochastic-Differential Equations
In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By ... En savoir plus
Investigations on Natural Frequencies of Individual Spherical and Ellipsoidal Bakery Yeast Cells
In this paper, a Finite Element (FE) and scaled-up experimental modal analysis are employed to estimate the natural frequencies of individual spherical and ellipsoidal cells. It is apparent that the mechanical properties of the living cells and particularly the natural frequencies might ... En savoir plus
Non-Newtonian Hemodynamics and Shear Stress Distribution in Three Dimensional Model of Healthy and Stented Coronary Artery Bifurcation
In this paper, a three-dimensional model of the coronary artery bifurcation is developed and physiological flow in the both healthy and stented coronary artery bifurcation is modeled using COMSOL Multiphysics. Wall shear stress induced by endovascular stents in the coronary artery ... En savoir plus
