Bioclogging in porous media: Model development and sensitivity to initial conditions [PDF]

open access: yesEnvironmental Modelling & Software, 2009
This work presents a numerical model able to simulate the effect of biomass growth on the hydraulic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled flow and reactive-transport code-PHWAT-was implemented. Laboratory experiments were used to validate the model.

An Implementation Methodology for the Online Tracking Simulation Architecture of the 660 MW USCFB

open access: yesEnergies, 2023
This paper studies the implementation strategy of an online tracking simulation system for the 660 MW ultra supercritical circulating fluidized bed boiler (USCFB). The establishment of the online system can be divided into offline and online phases.

Sensitivity to Initial Conditions in an Extended Activator--Inhibitor Model for the Formation of Patterns [PDF]

open access: yesActa Physica Polonica B, 2018
Despite simplicity, the synchronous cellular automaton [D.A. Young, Math. Biosci. 72, 51 (1984)] enables reconstructing basic features of patterns of skin. Our extended model allows studying the formatting of patterns and their temporal evolution also on the favourable and hostile environments.

On the sensitivity of a regional Arctic climate model to initial and boundary conditions [PDF]

open access: yesClimate Research, 2000
The sensitivity of Arctic atmospheric simulations to initial and boundary conditions was investigated with the high horizontal resolution regional climate model HIRHAM driven by observa- tional data analyses at the lateral and lower boundaries. Investigation of the constraint of the synoptic- scale flow in the specific circumpolar Arctic domain showed ...

Space Matters: Extending Sensitivity Analysis to Initial Spatial Conditions in Geosimulation Models [PDF]

open access: yesJournal of Artificial Societies and Social Simulation, 2019
Although simulation models of geographical systems in general and agent-based models in particular represent a fantastic opportunity to explore socio-spatial behaviours and to test a variety of scenarios for public policy, the validity of generative models is uncertain unless their results are proven robust and representative of 'real-world' conditions.

Simulating Landslide Generated Tsunamis in Palu Bay, Sulawesi, Indonesia

open access: yesGeosciences, 2023
The results of an extensive series of numerical experiments of the GNOM-LS model for modelling the physical and energy characteristics of tsunami waves generated by landslides are presented. Based on the published data on the tsunami on 28 September 2018

AN ANALYTICAL APPROACH TO AM2 MODEL FOR BATCH ANAEROBIC BIOREACTORS [PDF]

open access: yesCarpathian Journal of Electrical Engineering, 2021
The well-known AM2 model is commonly used for simulation of biotechnological processes of two-phases anaerobic digestions. Nevertheless, numerical simulation and graphical results usually obtained by solving the non-linear system of differential ...

[Comment on “Sensitivity of the global climate system to initial conditions” by A. A. Tsonis] Autoagressive models not sensitive to initial conditions

open access: yesEos, Transactions American Geophysical Union, 1992
A well‐known approach to studying the impact of greenhouse gases on climate is computer‐simulated general circulation models (GCMs) that integrate current understanding of the various factors influencing climate through a comprehensive mathematical model.

DAMAGE SPREADING IN THE BAK–SNEPPEN MODEL: SENSITIVITY TO THE INITIAL CONDITIONS AND EQUILIBRATION DYNAMICS [PDF]

open access: yesInternational Journal of Modern Physics C, 2003
The short-time and long-time dynamics of the Bak–Sneppen model of biological evolution are investigated using the damage spreading technique. By defining a proper Hamming distance measure, we are able to make it exhibit an initial power-law growth which, for finite size systems, is followed by a decay towards equilibrium.

Classical infinite-range-interaction Heisenberg ferromagnetic model:   Metastability and sensitivity to initial conditions [PDF]

open access: yesPhysical Review E, 2003
A N-sized inertial classical Heisenberg ferromagnet, which consists in a modification of the well-known standard model, where the spins are replaced by classical rotators, is studied in the limit of infinite-range interactions. The usual canonical-ensemble mean-field solution of the inertial classical $n$-vector ferromagnet (for which $n=3$ recovers ...
