The Balbi operational model, a simplified physical model for surface fires. Part I – modelling

Background Previously published versions of the ‘Balbi model’ describing surface fire propagation consist of a set of equations based on simplified conservation laws. Their main equation calculating the fire rate of spread (ROS) relied on an iterative process to account for the e...

The Balbi operational model, a simplified physical model for surface fires spread. Part II – model parameterisation and evaluation

Background The ‘Balbi model’ is a simplified physical model for surface fires which provides the main physical characteristics of a fire front and its rate of spread (ROS) as a function of general environmental conditions. In the first part of this work, we describe a simplificat...

A nested factor model for equity markets: reconciling multifractal stock returns and rough index volatilities

The Nested factor model was introduced by Chicheportiche et al. to represent non-linear correlations between stocks. Stock returns are explained by a standard factor model, but the (log)-volatilities of factors and residuals are themselves decomposed into factor modes, with a com...

Seismic Performance of Buckling-Restrained Braces Subjected to Subduction Interface Earthquake Demands

Abstract Five full-scale buckling-restrained brace (BRB) specimens, part of the second story of a 5-story steel buckling-restrained braced frame (BRBF), were tested experimentally to investigate their seismic response under demands imposed by long-distance subduction interface ea...
