The performance of simulated annealing (S-A) in nonlinear kinetic parameter estimation was studied and compared with the classical Levenberg /Marquardt (L /M) algorithm. Both methods were tested in the estimation of kinetic parameters using a set of three kinetic models of progressively higher complexity. The models describe the catalytic wet air oxidation of phenol carried out in a small-scale...

Kinetic model identification of metabolic networks is important, but still represents a significant challenge. The difficulties faced vary from the vast kinetic parameter search space to the lack of complete parameter identifiability. To meet these challenges, an incremental modeling approach is proposed here, including two key components—dynamic flux calculation and flux-based kinetic paramete...

In this work, zeolite 13X with porosity structure has been used as an adsorbent for adsorption of CO2 flue gas. The effect of operating conditions including pressure and time on adsorption capacity were investigated. The experiments conditions are constant temperature, the range of pressure 1 - 9 bar and the registration of adsorption capacity with passing of time. Experimental data were adjust...

We show theoretically that the mean turbulent dynamics can be described by a kinetic theory representation with single free relaxation time depends on space and time. A proper equation is constructed from Klimontovich-type for fluid elements, which satisfies Navier–Stokes hydrodynamics exactly. In suitably averaged form, energy plays role of temperature in standard molecular thermodynamics. flu...

Wheat straw is a renewable agricultural by-product that currently underutilized in the production of bioenergy and bioproducts due to its high ash content, as well transport costs low volumetric energy density. The thermogravimetric analysis this material produces derivative curves with single broad peak, making it difficult identify three conventional pseudo-components (cellulose, hemicellulos...

Kinetic modeling of metabolic pathways has become a major field of systems biology. It combines structural information about metabolic pathways with quantitative enzymatic rate laws. Some of the kinetic constants needed for a model could be collected from ever-growing literature and public web resources, but they are often incomplete, incompatible, or simply not available. We address this lack ...
