On the Use of Semi-empirical Flame Models for Spreading Chaparral Crown Fire

open access: yesFrontiers in Mechanical Engineering, 2019
Flame geometry plays a key role in shaping fire behavior as it can influence flame spread, radiative heat transfer and fire intensity. For wildland fire, thorough characterizations of flame geometry can help advance the derivation of comprehensive models

Estimation of Aboveground Biomass in Alpine Forests: A Semi-Empirical Approach Considering Canopy Transparency Derived from Airborne LiDAR Data

open access: yesSensors, 2010
In this study, a semi-empirical model that was originally developed for stem volume estimation is used for aboveground biomass (AGB) estimation of a spruce dominated alpine forest. The reference AGB of the available sample plots is calculated from forest

Sentinel-MSI and Landsat-OLI Data Quality Characterization for High Temporal Frequency Monitoring of Soil Salinity Dynamic in an Arid Landscape

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Although the Sentinel-MSI and Landsat-OLI are designed to be similar, they have different spectral, spatial and radiometric resolutions. In addition, relative spectral response profiles characterizing the filters responsivities of the both instruments ...

A semi-empirical approach to simulating the Dst index in global MHD models of Earth’s magnetosphere

open access: yesEarth and Planetary Physics
The Dst index has been commonly used to measure the geomagnetic effectiveness of magnetic storm events for several decades. Based on Burton’s empirical Dst model and the global magneto-hydrodynamic (MHD) simulation of Earth’s magnetosphere, here we ...

Early-Cycle Lifetime Prediction of LFP Batteries Using a Semi-Empirical Model and Chaotic Musical-Chairs Optimization

open access: yesEnergies
Efficiently predicting the lifespan of lithium iron phosphate (LFP) batteries early in their operational life is critical to accelerating the development of energy storage systems while reducing testing time, cost, and resource consumption.
