Climate change is a task of profound academic and societal relevance that promises to shape our actions for the planet’s sustainable future. Understanding the complex relationship between land transformations and temperature changes is crucial for effective decision-making in the face of climate change. This study uses a data-driven approach to ass...

Computer vision techniques can monitor the rotational speed of rotating equipment or machines to understand their working conditions and prevent failures. Such techniques are highly precise, contactless, and potentially suitable for applications without massive setup changes. However, traditional vision sensors collect a significant amount of data...

Electronic Legal Proceedings are a worldwide legal phenomena, allowing the use of computerized systems for the creation and monitoring of procedural acts in the most diverse legal bodies. On one hand, it allows greater transparency in the conduct of procedural acts, on the other, it has contributed to the bottleneck of open but unresolved lawsuits...

Eye tracking is a tool presented in many applications ranging from scientific research to commercial applications. One of them is assistive technologies that aim to help people with some disabilities, including communication. However, the applications usually require specific hardware components or a high computational cost. This work proposes the...

The Covid-19 pandemic, a disease transmitted by the SARS-CoV-2 virus, has already caused the infection of more than 120 million people, of which 70 million have been recovered, while 3 million people have died. The high speed of infection has led to the rapid depletion of public health resources in most countries. RT-PCR is Covid-19’s reference dia...

The technological growth of the last decades has brought many improvements in daily life, but also concerns on how to deal with electronic waste. Electrical and electronic equipment waste is the fastest-growing rate in the industrialized world. One of the elements of electronic equipment is the printed circuit board (PCB) and almost every electroni...

Applications of eye-tracking devices aim to understand human activities and behaviors, improve human interactions with robots, and develop assistive technology in helping people with some communication disabilities. This paper proposes an algorithm to detect the pupil center and user’s gaze direction in real-time, using a low-resolution webcam and...

The proliferation of the SARS-CoV-2 virus to the whole world caused more than 250,000 deaths worldwide and over 4 million confirmed cases. The severity of Covid-19, the exponential rate at which the virus proliferates, and the rapid exhaustion of the public health resources are critical factors. The RT-PCR with virus DNA identification is still the...

Semáforos podem ser causadores de congestionamentos, por falhas ocorrentes e pela falta de sincronia entre eles. Incialmente foram investigados os sensores para realizar a contagens de veículos, tendo sido adotado o sensor de laço indutivo, por tratar-se de sensor de grande confiabilidade já que não demostra erro de leitura quando submetido a adver...

Uma rede de sensores sem fio (RSSF) para monitoração de descargas parciais em cadeias de isoladores de alta tensão foi previamente desenvolvida e encontra-se em operação há aproximadamente três anos. As descargas parciais ocorrem quando há poluição depositada sobre as cadeias de isoladores e a umidade relativa do ar está elevada. Devido à nat...

The loss of insulation capacity caused by pollution deposition on insulator strings can be inferred from the analysis of the electric arcs due to partial discharges on the insulators. The partial discharges also cause pulses superposed to the leakage current signal. An optical sensor system network was developed and installed in the northeast regio...
