Passive reflectance sensing using optimized two- and three-band spectral indices for quantifying the total nitrogen yield of maize

Computers and Electronics in Agriculture, 2020
Precision nitrogen (N) management requires accurate and effective quantification of the total nitrogen yield (TNY) crops. Thus, this study aimed at establishing the robust prediction model to quantify the TNY of maize plants across growth stages ...

Efficacy of extracting indices from large‐scale acoustic recordings to monitor biodiversity

open access: yesConservation Biology, 2018
Passive acoustic monitoring could be a powerful way to assess biodiversity across large spatial and temporal scales. However, extracting meaningful information from recordings can be prohibitively time consuming.

Combining both spectral and textural indices for alleviating saturation problem in forest LAI estimation using Sentinel-2 data

Geocarto International, 2022
Leaf area index (LAI) is an important structural parameter that controls energy, water, and gas exchanges of plant ecosystems. At present, remote sensing techniques, especially passive optical remote sensing, are the most widely used approaches to ...

Passivity analysis and passivation of feedback systems using passivity indices

2014 American Control Conference, 2014
Passivity indices are used to measure the excess or shortage of passivity. While most of the work in the literature focuses on stability conditions for interconnected systems using passivity indices, here we focus on passivity and passivation of the feedback interconnection of two input feed-forward output-feedback (IF-OF) passive systems.

Passivity Analysis and Passivation of Interconnected Event-Triggered Feedback Systems Using Passivity Indices

IFAC Proceedings Volumes, 2014
Abstract In this paper, passivity and passivation problems for event-triggered feedback interconnected systems are addressed. We consider passivity in two event-triggered control schemes based on the location of the event-triggered samplers: sampler at plant output and sampler at controller output.
