Assessing the Sensitivities of Input–Output Methods for Natural Hazard‐Induced Power Outage Macroeconomic Impacts

open access: yesRisk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT Power outages are a substantial global issue across both advanced and developing countries, affecting economic productivity and growth. Consequently, numerous studies have examined the potential macroeconomic impacts of these disruptions, employing a wide variety of modeling methods and data parameterization techniques.

Efficient polarimetric BRDF model

open access: yesOptics Express, 2015
The purpose of the present manuscript is to present a polarimetric bidirectional reflectance distribution function (BRDF) model suitable for hyperspectral and polarimetric signature modelling. The model is based on a further development of a previously published four-parameter model that has been generalized in order to account for different types of ...

Improving Soil Moisture Retrieval by Combining MODIS BRDF and CYGNSS Data

open access: yesJournal of Remote Sensing
Soil moisture (SM) retrieval methods based on machine learning from the Cyclone Global Navigation Satellite System (CYGNSS) data primarily rely on Normalized Difference Vegetation Index (NDVI) to characterize vegetation information.

Adaptive slices for acquisition of anisotropic BRDF

open access: yesComputational Visual Media, 2018
BRDF continues to be used as a fundamental tool for representing material appearance in computer graphics. In this paper we present a practical adaptive method for acquisition of anisotropic BRDF, based on sparse adaptive measurement of the complete four-

BRDF workshop

open access: yes, 2012
This thesis develops an application for interactive experiments with BRDF functions. Arbitrary BRDF function may be specified with an analytic formula, including arbitrary number of parameters. A simple scene is displayed, using specified BRDF.

Evaluation of Medium Spatial Resolution BRDF-Adjustment Techniques Using Multi-Angular SPOT4 (Take5) Acquisitions

open access: yesRemote Sensing, 2015
High-resolution sensor Surface Reflectance (SR) data are affected by surface anisotropy but are difficult to adjust because of the low temporal frequency of the acquisitions and the low angular sampling.

Estimating Surface BRDF/Albedo Over Rugged Terrain Using an Extended Multisensor Combined BRDF Inversion (EMCBI) Model

open access: yes, 2022
Land surface albedo is a crucial variable of earth energy budget and global climate change. Rugged terrain significantly impacts surface bidirectional reflectance distribution function (BRDF) and the subsequent albedo retrieval using satellite remote ...

Hypernetworks for Generalizable BRDF Representation

open access: yes
In this paper, we introduce a technique to estimate measured BRDFs from a sparse set of samples. Our approach offers accurate BRDF reconstructions that are generalizable to new materials. This opens the door to BDRF reconstructions from a variety of data sources.
