Modeling of Vegetation Permittivity at Microwave Frequencies
TLDR
When materials are to be treated with microwaves for different purposes such as drying, online moisture measurements, disinfestation, and remote sensing, thorough knowledge of the material dielectric properties becomes extremely important. Expand

Microwave Dielectric Properties of Alfalfa Leaves From 0.3 to 18 GHz
TLDR
We measured permittivity of stacked leaves of alfalfa (Medicago sativa) were measured with a network analyzer and a coaxial probe, and the effect of moisture content (MC: 12%-73% wet basis), frequency (300 MHz to 18 GHz), bound water (Cole-Cole dispersion equation), temperature (-15°C and 30°C), leaf-orientation, and pressure.

Elimination of Cruptolestes Ferrungineus S. in Wheat by Radio Frequency Dielectric Heating at Different Moisture Contents
Radio frequency (RF) dielectric heating was tested to control Cryptolestes ferrungineus S. in the bulk wheat samples (ca.152g, dia. = 50mm, ht. = 100mm) at the MCs (%, w. b.) of 12, 15, and 18 using… Expand

A two-camera machine vision in predicting alpha-amylase activity in wheat
Sprout damage in wheat is a serious problem worldwide because damaged wheat kernels contain alpha-amylase, an enzyme that causes poor baking quality of wheat. A two-camera machine vision (MV) with a… Expand

A two-camera machine vision approach to separating and identifying laboratory sprouted wheat kernels
A proof-of-concept for a two-camera machine vision (MV) to classify the laboratory sprouted wheat kernels into sound, sprout-damaged, or severely sprout-damaged classes was developed. The marker… Expand
