The growing environmental concern over the use of fossil fuels calls for alternative sources of energy with smaller environmental footprint, and biomass-derived fuels have been extensively investigated as a substitute. In biofuels production, the development of reaction networks and kinetic models is unquestionably a major challenge due to the difficulty in characterizing the reaction products. Therefore,...
This paper proposes to extend the dynamical analysis results on chemical tubular reactors presented in [3] to two typical bioprocess models : a basic tubular bioreactor model, and a denitrifying biofilter model. The tools used for the analysis are those of the infinite dimensional system theory (e.g. [2]). In the paper we show the existence of solutions for the studied models, and emphasize stability...
This study deals with mathematical modeling for predicting Chlamydomonas reinhardtii growth under light attenuation and sulfur deprived conditions leading to hydrogen production in photobioreactor. The strong interactions between biological and physical phenomena require complex mathematical expressions with important number of parameters that have to be identified on the available experimental data...
Based on characteristics of lake eutrophication, total phosphorus (TP), total nitrogen (TN), chemical oxygen demand(CODMn), secchi disk depth (SD) and biomass (BIO) were chosen as evaluation indexes. Aiming at the problem being too complex for the present evaluation methods on lake eutrophication, a new method, improved set pair analysis model was used to solve the complicated non-linear relation...
We report about two specific breakthroughs, relevant to the mathematical modeling and numerical simulation of tissue growth in the context of cartilage tissue engineering in vitro . The proposed models are intended to form the building blocks of a bottom-up multiscale analysis of tissue growth, the idea being that a full microscale analysis of the construct, a 3-D partial differential equation (PDE)...
Sensitivity analysis is a powerful tool which gives important insights regarding parameterization in the process of model design. For an empirical model like the Greenlab model of plant growth relying on parameter estimation from experimental data, such study should open new perspectives for model identification. This study was aimed at analyzing the sensitivity of GreenLab model for maize. When the...
A growing interest emerges for the application of plant functional-structural models to study the influence of topological development on plant growth. This kind of study is classically done through virtual experiments on simulated plants to analyze the effects of architectural changes on the model outputs. In this paper, we take advantage of the mathematical formalism developed for describing plant...
