Fire modelling of passenger trains
ENGLISH ABSTRACT: Train fires continue to pose a significant threat both internationally and in South Africa, particularly with the increasing prevalence of emerging hazards such as lithium-ion battery devices carried by passengers. With the introduction of the new X’Trapolis Mega fleet, it is …

Integrate-and-fire modelling of neuronal systems with modulatory properties
The mathematical modelling of behaviour at the single neuron level is an important part of computational neuroscience. Conductance-based models remain dominant because of their biophysical interpretation. Nevertheless, their high dimensionality and number of parameters complicate mathematical …

Improving the regulatory acceptance and numerical performance of CFD based fire-modelling software
… of Computational Fluid Dynamics (CFD) based fire modelling software, specifically its application and performance. Initially a novel CFD based fire suppression model was developed (FIREDASS). The FIREDASS (FIRE Detection And Suppression Simulation) programme was concerned with the development …

The use of GIS for the development of a fully embedded predictive fire model
Fire is very important for maintaining balance in the ecosystems and is used by fire management across the world to regulate growth of vegetation in natural conservation areas. However, improper management of fire may lead to hazardous behaviour. Fire modelling tools are implemented to provide fire …

An investigation into automation of fire field modelling techniques
… thesis has produced a prototype system based on fire field modelling techniques for use by members of the Fire Safety Engineering community who are not expert in modelling techniques. The system captures the qualitative reasoning of an experienced modeller in the assessment of room geometries in …

The Use of Numerical Methods to Interpret Polymer Decomposition Data
Polymer decomposition is the key to understanding fire behaviour. It is a complex process involving heat transfer, breakdown of the polymer chain, volatile fuel formation and gasification occurring as a moving interface through the polymer bulk. Two techniques, chemical analysis using STA-FTIR, and …

The derivation of fire hazard indices and burning prescriptions from climatic and ecological features of the fynbos biome
This study deals with the development of fire behaviour prediction and fire danger rating systems, and their potential use in fynbos catchment areas. Fynbos catchments are managed for sustained water yields and for nature conservation. Wildfires have always been a problem in these areas, and early …
