This paper describes recent techniques developed to simplify the analysis and improve the accuracy of modeling thermal bridges. Two techniques are presented for determining the overall wall thermal resistance. The first is a hand technique using weighting factors between the isothermal planes and parallel path results. The second is a MS-WINDOWS finite-volume computer program. A technique is pr...

One-dimensional slow invariant manifolds for dynamical systems arising from modeling unsteady, isothermal, isochoric, spatially homogeneous, closed reactive systems are calculated. The technique is based on global analysis of the composition space of the reactive system. The identification of all the system’s finite and infinite critical points plays a major role in calculating the system’s slo...

A statistical continuum model is developed in the present study which uses microstructural information for a two-phase Ti-6Al-4V alloy to simulate microstructure evolution during hot isothermal compression. Current models of prediction often use finite element methods. However, here does not rely onfinite methods and thus can be performed much faster with less computational resources without sa...

Cracks, veins, joints, faults, and ocean crusts are strong discontinuities of different length scales that can be found in many geological formations. While the constitutive laws for frictional slip these interfaces have been focus decades-long geophysical research, capturing evolving geometry such as branching, coalescence, corresponding interplay between mode II crack growth compression remai...

Flavodoxin (Fld) has been demonstrated to bind to ferredoxin- NADP(+) reductase A (FprA) in Pseudomonas putida. Two residues (Phe(256), Lys(259)) of FprA are likely to be important for interacting with Fld based on homology modeling. Sitedirected mutagenesis and pH-dependent enzyme kinetics were performed to further examine the role of these residues. The catalytic efficiencies of FprA-Ala(259)...

We present a modeling approach that enables numerical simulations of a boiling Van der Waals fluid based on the diffuse interface description. A boundary condition is implemented that allows in and out flux of mass at constant external pressure. In addition, a boundary condition for controlled wetting properties of the boiling surface is also proposed. We present isothermal verification cases f...
