Topological Higher Gauge Theory - from BF to BFCG theory
F. Girelli, H. Pfeiffer, E. M. Popescu
We study generalizations of 3- and 4-dimensional BF-theory in the context of higher gauge theory. First, we construct topological higher gauge theories as discrete state sum models…
Carbon Nanotube Thin Film Field Emitting Diode: Understanding the System Response Based on Multiphysics Modeling
N. Sinha, D. Roy Mahapatra, J. T. W. Yeow +2
In this paper, we model the evolution and self-assembly of randomly oriented carbon nanotubes (CNTs), grown on a metallic substrate in the form of a thin film for field emission un…
Effect of Internal Viscosity on Brownian Dynamics of DNA Molecules in Shear Flow
Jack Yang, Roderick V. N. Melnik
The results of Brownian dynamics simulations of a single DNA molecule in shear flow are presented taking into account the effect of internal viscosity. The dissipative mechanism of…
Numerical Model For Vibration Damping Resulting From the First Order Phase Transformations
Linxiang X. Wang, Roderick V. N. Melnik
A numerical model is constructed for modelling macroscale damping effects induced by the first order martensite phase transformations in a shape memory alloy rod. The model is cons…
Simulation of Phase Combinations in Shape Memory Alloys Patches by Hybrid Optimization Methods
Linxiang X. Wang, Roderick V. N. Melnik
In this paper, phase combinations among martensitic variants in shape memory alloys patches and bars are simulated by a hybrid optimization methodology. The mathematical model is b…
Finite Volume Analysis of Nonlinear Thermo-mechanical Dynamics of Shape Memory Alloys
Linxiang X. Wang, Roderick V. N. Melnik
In this paper, the finite volume method is developed to analyze coupled dynamic problems of nonlinear thermoelasticity. The major focus is given to the description of martensitic p…
