Evaluating Unmanned Aerial Vehicle Images for Estimating Forest Canopy Fuels in a Ponderosa Pine Stand

Remote Sensing, 2018
Forests in the Southwestern United States are becoming increasingly susceptible to large wildfires. As a result, forest managers are conducting forest fuel reduction treatments for which spatial fuels and structure information are necessary.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Mechanism Analysis and Optimal Design of Return Impact of a Certain Aircraft Canopy Actuator

Actuators
During the closure of a specific aircraft canopy, oil leakage occurs from the pressure tank’s overflow port in the gas–liquid control system. This issue often occurs during closure, potentially leading to reduced system oil and impacting the normal ...

Flexible Chromatic VIS‐IR Meta‐Textile for Multi‐Scenario Stealth

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A flexible chromatic meta‐textile was developed for multi‐spectral stealth across VIS‐IR bands, combining low color difference, ultralow infrared emissivity, and passive radiative cooling. The textile exhibits excellent VIS wide‐angle compatibility, optical durability, and mechanical flexibility, offering a promising solution for advanced stealth ...

Modeling canopy-induced turbulence in the Earth system: a unified parameterization of turbulent exchange within plant canopies and the roughness sublayer (CLM-ml v0)

, 2017
. Land surface models used in climate models neglect the roughness sublayer and parameterize within-canopy turbulence in an ad hoc manner. We implemented a roughness sublayer turbulence parameterization in a multilayer canopy model (CLM-ml v0) to test if

Seismic Performance and Generalized Damage Risk of Modular Cross Laminated Timber Houses Across Ten United States Cities

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Housing shortages in the United States and the pursuit of sustainable and resilient communities have positioned cross‐laminated timber (CLT) housing as a promising alternative due to the ability to design for modularity, ease of construction, and low embodied carbon performance.

Arboreal camera trapping reveals diel-vertical migrations in arboreal wildlife of the Peruvian Amazon rainforest

Environmental Research: Ecology
Tropical forests harbor much of Earth’s biodiversity, with the ground to emergent canopy forming dynamic three-dimensional habitats. Arboreal and semi-arboreal species navigate the vertically heterogeneous environment, in temperature, light, predation ...

Assessment of Canopy Chlorophyll Content Retrieval in Maize and Soybean: Implications of Hysteresis on the Development of Generic Algorithms

Remote Sensing, 2017
Canopy chlorophyll content (Chl) closely relates to plant photosynthetic capacity, nitrogen status and productivity. The goal of this study is to develop remote sensing techniques for accurate estimation of canopy Chl during the entire growing season ...

Experimental Analysis of Fire Behavior in Pine Forests and Agricultural Fields: Large‐Scale Tests Conducted Within the European TREEADS Project

Fire and Materials, EarlyView.
ABSTRACT Two large‐scale experiments investigated fire spread mechanisms in vegetation ground fires in a pine forest and an agricultural field within the European TREEADS project. The tests, conducted in Saxony‐Anhalt and Brandenburg, targeted regions with dry, sandy soils and extensive pine stands and aim to improve suppression strategies and wildfire
