The preservation of the environment has become a priority and subject that is receiving more attention. This particularly important in field precision agriculture, where pesticide herbicide use controlled. In this study, we propose to evaluate ability deep learning (DL) convolutional neural network (CNNs) technology detect weeds several types crops using perspective proximity images enable loca...

BACKGROUND Although many malaria control programmes in sub-Saharan Africa use indoor residual spraying with long-lasting insecticidal nets (LLINs), the two studies assessing the benefit of the combination of these two interventions gave conflicting results. We aimed to assess whether the addition of indoor residual spraying to LLINs provided a significantly different level of protection against...

The accurate weed detection is the premise for precision prevention and control of weeds in fields. Machine vision offers an effective means to detect accurately. For various carrot fields, this paper improves You Only Look Once v4 (YOLO v4) into a lightweight model called YOLO v4-weeds among seedlings. Specifically, backbone network original YOLOv4 was replaced with MobileNetV3-Small. Combined...

This Chagas disease prevention project via housing improvement aims to determine the efficiencyof different interventions in vector control. The following study describes the target communities, disease magnitude, and housing improvements. Transmission levels are analysed from an ecological and socioeconomic perspective. Special interest was focused on the peridomicile as the origin of domicili...

Spraying techniques have been undergoing continuous evolution in recent decades. This paper presents part of the research work carried out in Spain in the field of sensors for characterizing vineyard canopies and monitoring spray drift in order to improve vineyard spraying and make it more sustainable. Some methods and geostatistical procedures for mapping vineyard parameters are proposed, and ...

Multi-electrode plasma torches are becoming increasingly popular in the thermal spray community due to their good stability and high power plasma jet even when operated with inert gases. Currently the models in use feature either three cathodes and a single anode or three individual anodes connecting to a single cathode. The motivation for development of these plasma torches is based on the inh...
