Edge-computing smart irrigation controller using LoRaWAN and LSTM for predictiv...
Baseca, Carlos Cambra; Dionísio, Rogério Pais; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.MEnhancing sustainability in agriculture has become a significant challenge today where in the current context of climate change, particularly in countries of the Mediterranean area, the amount of water available for irrigation is becoming increasingly limited. Automating irrigation processes using affordable sensors can help save irrigation water and produce almonds more sustainably. This work presents an IoT-e...
Preserve or visit? The role of electric mobility in the balance between tourism...
Ramos, George; Dionísio, Rogério Pais; Pereira, PaulaThis article contributes to the debate on sustainable electric mobility as a beneficial element for tourism activities in protected areas. While the topic of sustainable mobility is not new, the recent advancement of electromobility has reignited research interest, predominantly in urban contexts but with promising potential for application in natural spaces. Our objective is to determine the potential for elec...
Establishing a regional industry 4.0 electronics hub: The GreenUpPCB model
Dionísio, Rogério Pais; Ünal, IremThis chapter presents GreenUpPCB as a regional Industry 4.0 hub for electronics repair and retrofitting, based in Castelo Branco, Portugal. The initiative combines artificial intelligence, machine vision, 3D printing, and automation to extend the life cycle of obsolete printed circuit boards, particularly in renewable energy systems and railway rolling stock. By promoting circular economy practices and reducing...
Nyon-data, a fall detection dataset from a hinged board apparatus
Dionísio, Rogério Pais; Rosa, Ana Rafaela; Jesus, Cassandra Sofia dos SantosFalls are one of the causes of severe hilliness among elders, and the COVID-19 pandemic increased the number of unattended cases because of the social distancing measures. This study aims to create a dataset that collects the data from a 3-axis acceleration sensor fixed on a hinged board apparatus that mimics a human fall event. The datalogging system uses off-the-shelf devices to measure, collect and store the...
Design and integration of an elastic sensor sheet for pressure ulcer prediction...
Mohammad Amini, Mohammad; Sheikholeslami, Davood Fanaei; Dionísio, Rogério Pais; Heravi, Ahmadreza; Faghihi, MahdiThis paper discusses the design and integration of an elastic sensor sheet for SENSOMATT, a smart device that predicts pressure ulcers caused by prolonged skin pressure. It covers the mechanical and electrical aspects of the sensor sheet design, including material selection, mould and tooling design, and network design. The paper describes testing of different configurations of the sensor sheet and various netw...
Using smart traffic lights to reduce CO2 emissions and improve traffic flow at ...
Santos, Osvaldo; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.; Dionísio, Rogério PaisReducing CO2 emissions is currently a key policy in most developed countries. In this article, we evaluate whether smart traffic lights can have a relevant role in reducing CO2 emissions in small cities, considering their specific traffic profiles. The research method is a quantitative modelling approach tested by computational simulation. We propose a novel microscopic traffic simulation framework, designed to...
Digital twin environment for Forestry 4.0 application using a CAN Bus architecture
Spencer, Geoffrey; Dionísio, Rogério Pais; Neto, Luis; Torres, Pedro; Gonçalves, GilThis paper presents a digital twin demonstrator of a forest harvesters and wood processing machines. The demonstrator is a cyber-physical system that allow the emulation and identification of faults that may occur during regular machine operations. The proposed solution includes a CAN Bus communication between several electronic controller units connected to sensors and actuators.
Cloud services for smart farming : a case study of the Veracruz Almond Crops in...
Fidalgo, Filipe; Santos, Osvaldo; Oliveira, Ângela; Metrôlho, J.C.M.M.; Ribeiro, Fernando Reinaldo; Candeias, Antonino; Rebelo, Jorge; Rodrigues, PauloEfficient use of resources is a critical factor in almond crops. Technological solutions can significantly contribute to this purpose. The VeraTech project aims to explore the integration of sensors and cloud-based technologies in almond crops for efficient use of resources and reduction of environmental impact. It also makes available a set of relevant and impactful performance indicators in agricultural activ...
PoPu-Data: a multilayered, simultaneously collected lying position dataset
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.; Santos, Adriana; Dionísio, Rogério Pais; Amini, MohammadThis study presents a dataset containing three layers of data that are useful for body position classification and all uses related to it. The PoPu dataset contains simultaneously collected data from two different sensor sheets—one placed over and one placed under a mattress; furthermore, a segmentation data layer was added where different body parts are identified using the pressure data from the sensors over ...
Nyon : a ubiquitous fall detection device for elders
Jesus, Cassandra Sofia dos Santos; Rosa, Ana Rafaela; Dionísio, Rogério PaisFalls are one of the main causes of mortality and morbidity in the elderly worldwide. This had let to the research and development of electronic fall-detection systems. We propose a complete fall-detection system, that combines a wearable device (called Nyon) and a message microservice (for email and SMS) to alert caregiver every time a fall occurs. The wearable uses a simple threshold method and has the capabi...
