Non-intrusive low-cost IoT-based hardware system for sustainable predictive mai...

Brito, Sergio; Azinheira, Gonçalo; Semião, Jorge; Sousa, Nelson; Pérez Litrán, Salvador

Industrial maintenance has shifted from reactive repairs and calendar-based servicing toward data-driven predictive strategies. This paper presents a non-intrusive, low-cost IoT hardware platform for sustainable predictive maintenance of rotating machinery. The system integrates an ESP32-S3 sensor node that captures vibration (100 kHz) and temperature data, performs local logging, and communicates wirelessly. A...

Effects of temperature and mobility on COVID-19 incidence

Rocha, Vanusa; Afreixo, Vera; Sousa, Nelson

  Background/Objective: The purpose of this study was to evaluate the association between COVID-19 weekly case numbers with the trend, average temperature (AT) and mobility (MOB) at the national level and by regions, in Portugal. Methods: We compiled a weekly dataset including COVID-19 case numbers, average temperature and mobility during the period of March 23, 2020, to August 30, 2022. Negative bino...

Improvement on fuel characteristics of biomass and refused derived fuel with to...

Azpilicueta, Ander; Paudel, Pramod; Sousa, Nelson

The search for sustainable energy alternatives has been increasingly important, not only because the depletion of fossil fuels, but also due to the necessary reduction in the emission of greenhouse gases. The use of renewable energy has contributed to the mitigation of this problem, but this doesn’t always adapt to the requirements of energy demand. The energy of biomass, in particular by the combustion of vege...


Monitoring of physical activity levels of guide dog owners – a preliminary study

Laranjo, Luis; Sousa, Nelson; Marmeleira, José

Despite the well-documented benefits of regular physical activity, people with disabilities are often challenged with too many barriers that discourage an active lifestyle. This is particularly evident among people with visual impairments (VI). Previous studies have shown that adults with VI are significantly less active than the general population, and do not meet the physical activity recommendations of the W...

Photovoltaic solar system for a smart bus shelter at Faro Airport

Sousa, Nelson; Pires Rosa, Manuela; Baioa, Luís; Costa, Cláudio

In this work, a photovoltaic system solution is studied for power-supply in an accessible and smart bus stop. In addition to lighting, the bus stop is equipped with a digital kiosk and a computer system to offer information to passengers and provide aid to people with reduced mobility. Several approaches in the integration of photovoltaic energy have been explored, demonstrating that the best solution is not a ...


Paragens de autocarro inteligentes e inclusivas

Rodrigues, Joao; Pires Rosa, Manuela; Viegas, Micael; Turner, Daniel; Veiga, Ricardo; Sousa, Nelson

Apresentam-se diferentes conceitos que determinam uma paragem inteligente e inclusiva, criando-se assim uma paragem de autocarros inovadora desde à geração da sua própria energia, tornando-a autossuficiente e sustentável, à integração na rede de autocarros para comunicação da quantidade de utilizadores à espera, até à criação de um ecrã interativo que se adapta às necessidades de qualquer utilizador através de ...
