Microwave time domain reflectometry

Electronics Letters, 2005
A new time domain reflectometry algorithm is presented. It is intended for identification of the impedance profile of the non-uniform lossless transmission line. Experimental results are presented to illustrate the validity of this new technique.

Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Thin and Compact Versus Thick and Porous Fouling Layers in the Emulsion Polymerization of Acrylates and Vinyl Acetates Studied In Situ With a Quartz Crystal Microbalance (QCM)

Journal of Applied Polymer Science, Volume 143, Issue 21, June 5, 2026.
ABSTRACT Building on a quartz crystal microbalance with dissipation monitoring (QCM‐D), fouling in emulsion polymerization was compared between acrylate dispersions stabilized with a mobile, anionic surfactant and dispersions of poly(vinyl acetate‐co‐vinyl neodecanoate), PVAc, stabilized with polyvinyl alcohol, PVOH.

Enhanced complex wire fault diagnosis via integration of time domain reflectometry and particle swarm optimization with least square support vector machine

IET Science, Measurement & Technology
Urban power systems rely on intricate wire networks, known as the power grid, which form the essential electric infrastructure in cities. While these networks transmit electricity from power plants to consumers, they are vulnerable to faults caused by ...

Reengineering the Baldree Traffic Simulator for turfgrass wear and traffic research

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Historically, turfgrass researchers utilized the Baldree Traffic Simulator (BTS) to imitate foot traffic for the evaluation of athletic field wear tolerance and performance. Research was conducted to reengineer the BTS “feet” to improve adaptability and compatibility with other aerification units and determine biophysical effects on two native

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Water percolation estimated with time domain reflectometry (TDR) in drainage lysimeters

Revista Brasileira de Ciência do Solo, 2013
Due to the difficulty of estimating water percolation in unsaturated soils, the purpose of this study was to estimate water percolation based on time-domain reflectometry (TDR).
