Comparative analysis of RNN versus IIR digital filtering to optimize resilience to dynamic perturbations in pH sensing for vertical farming

Agrosystems, Geosciences & Environment
Vertical farming (VF) refers to systems of agriculture where crops are grown in trays stacked vertically by exposing them to artificial light and using sensing technology to improve product quality and yield.

Mitigating light pollution impacts on arthropods based on light-emitting diode properties. [PDF]

Conserv Biol
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

AnimalTA: A highly flexible and easy‐to‐use program for tracking and analysing animal movement in different environments

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1699-1707, July 2023., 2023
Abstract Computer programs for video tracking of animal movement are evolving increasingly efficient, using complex algorithms or artificial intelligence systems. Despite the consequent progress in this field, researchers still face some fundamental problems in the use of such programs. For example, the best‐performing programs are often uneasy to use,

Mauritia flexuosa fruit production increases with increasing palm height in the Peruvian Amazon

PLANTS, PEOPLE, PLANET, Volume 4, Issue 6, Page 599-604, November 2022., 2022
Fruit number, size, and allometric relationships were evaluated in the Peruvian Amazon for Mauritia flexuosa, a socioeconomically important palm with conservation concerns due to destructive harvest. Significant relationships were found between total fruit number and both palm height and fruit volume. Taller palms experience more crown illumination and

Exploiting Light Directionality for Image‐Based 3D Reconstruction of Non‐Collaborative Surfaces

The Photogrammetric Record, Volume 37, Issue 177, Page 111-138, March 2022., 2022
The paper investigates the effect of light directionality and the fusion of multiple images to improve the quality of photogrammetric 3D reconstruction of complex surfaces (textureless and shiny). We present an image capturing system that utilizes multiple light sources to highlight roughness which is not visible in traditional diffuse images ...

Estimating canopy fuel load with hemispherical photographs: A rapid method for opportunistic fuel documentation with smartphones

Methods in Ecology and Evolution, Volume 12, Issue 11, Page 2101-2108, November 2021., 2021
Abstract Canopy fuel load (CFL) affects wildfire intensity and is a critical input for fire behaviour models; however, measuring CFL in the field is time‐consuming and costly. Until recently, hemispherical photographs have been unable to adequately describe canopy metrics in non‐diffuse light conditions.

El entorno construido en los programas diseñados para promover la actividad física entre las niñas, niños y jóvenes latinos que viven en Estados Unidos y América Latina

Obesity Reviews, Volume 22, Issue S5, Octubre 2021., 2021
Resumen Prevenir la obesidad entre los jóvenes latinos que viven en Estados Unidos y en países latinoamericanos requiere reconocer la especificidad de los contextos y las interacciones entre actividad física (AF) y entorno construido (EC). El objetivo de este artículo es avanzar en la agenda de investigación sobre el EC y la AF con el fin de prevenir ...

Reducing the blue spectrum of artificial light at night minimises insect attraction in a tropical lowland forest

Insect Conservation and Diversity, Volume 14, Issue 2, Page 247-259, March 2021., 2021
Over 15 000 insects (18 orders) were captured across three lamp types emitting different spectra of light in a Peruvian Amazon forest previously naïve to artificial illumination. White 3000 K LED lamps attracted far more insects (morphospecies and individuals), including groups containing important disease vectors, than yellow and amber‐filtered 3000 K
