Analysis and Simulation of Kinetic Model for Active Suspensions
… this research, we study the recently proposed kinetic model for active suspensions, where the active particles are assumed to be rigid rod and are driven in the suspension either by their own biological/chemical forces or external electric/magnetic fields. We first study the stability of the …

Kinetic model reduction using integer and semi-infinite programming
In this work an optimization-based approach to kinetic model reduction was studied with a view to generating reduced-model libaries for reacting-flow simulations. A linear integer formulation of the reaction elimination problem was developed in order to allow the model reduction problem to be …

Development of a Kinetic Model for Low Temperature Fischer-Tropsch Synthesis
… an effective description of the FT reaction kinetics. This study therefore focuses on the development of a kinetic model for low temperature FT (LTFT) synthesis to improve understanding of the reaction behaviour and aid in the development of a biomass-to-liquid process route. Although the …

Development of a semi–empirical reaction kinetic model for PEM fuel cells
… followed by the ORR.This study developed a kinetic model from conventional kinetic isotherms and it is proposed that an associative adsorption mechanism occurs at a low overpotential resulting in the dissociation of the hydroperoxyl species determining the rate of the ORR at the cathode of …

Development of a generalised kinetic model for the combustion of hydrocarbon fuels
The aim of this work is to find a generalised model for the combustion of hydrocarbons. Predicted temperature-time profiles can be obtained from detailed combustion kinetics, which can be used to derive a generalised model. If the generalised model can predict results from the detailed model it can …

Deterministic numerical simulation of the Boltzmann and kinetic model equations for classical and quantum dilute gases
… fast spectral method, we check the accuracy of kinetic model equations to find out at what flow regime can the complicated Boltzmann collision kernel be replaced by the simple kinetic ones. We also solve the collective oscillation of quantum gas confined in external trap and compare the …

Development of a Kinetic Model to Investigate the Effect of Compositional Variation and a Processing Condition on the Solid-State Degradation of Gabapentin
… than gabapentin, causing seizures in animal models. The United States Pharmacopeia (USP) limits the content of lactam in gabapentin formulations to 0.4% w/w. A number of patents have been issued for solid dosage forms formulated to stabilize gabapentin. Despite these efforts, factors …

The Membrane Topology of the Microsomal Cytochromes P450: Interfacial Characterization of Protein Structure
… lipid bilayer. The data has been fit to a kinetic model that incorporates a semi-empirical available surface function to account for the effect of steric interactions between pre-adsorbed molecules. The results indicate that P450 does in fact contain a peripheral binding interaction. …

Mathematical Modeling of Reductive Transformation Kinetics of Branched Degradation Pathways of Groundwater Contaminants
… point of view, the capability to simulate the kinetics of these reductive transformation reactions coupled with other attenuation processes in the subsurface (e.g., sorption, advection, and dispersion) is required for site-specific solute transport models. A kinetic model based on …

Alpha-T-T and T-T-alpha-T diagrams in intelligent processing of thermosetting composites
The majority of existing models for processing in thermoset matrix composites concentrate nearly exclusively on heat and mass transfer problems and account for material-related aspects in a very simplified manner The objective of this work is to provide that missing element by proposing a clearly …
