Human Activity Recognition (HAR) is one of the most popular research topics thanks to its usefulness in providing targeted, meaningful assistance to older adults. Because of the aging of the population in first-world countries, it becomes increasingly important to find innovative solutions that reduce risks associated with aging-in-place policies. HAR proposes solutions that are based on Ambient I...Show More
One of the biggest challenges faced by older adults is the risk of falling. Falls and the fear of falling cause serious physical and mental health issues. They are also a very impacting factor on the independence of the individual. This paper approaches the problem through the view of a population afflicted by the self-neglect syndrome. Therefore, we propose the NAOREA system, using monocular came...Show More
Fall detection is a major challenge for researchers. Indeed, a fall can cause injuries such as femoral neck fracture, brain hemorrhage, or skin burns, leading to significant pain. However, in some cases, trauma caused by an undetected fall can get worse with the time and conducts to painful end of life or even death. One solution is to detect falls efficiently to alert somebody (e.g., nurses) as q...Show More
This paper is related to a project aiming at discovering weak signals from different streams of information, possibly sent by whistleblowers. The study presented in this paper tackles the particular problem of clustering topics at multi-levels from multiple documents, and then extracting meaningful descriptors, such as weighted lists of words for document representations in a multi-dimensions spac...Show More
Induction machines are omnipresent in industry because of their sturdiness and their ease of implementation. Nevertheless, these electrical motors still concede failures [e.g., interturn short circuit (ITSC) and broken rotor bar], which may lead to unplanned shutdowns. Consequently, manufacturing industries invest significant resources to avoid them with maintenance. Some studies have been achieve...Show More
Industries are innovating, developing and optimizing production line to improve productivity, quality and robustness of the production in order to be competitive. The different existing goals of optimization, such as the computation of closed-loop drive-fed motors, the reduction of energy consumption or the detection of motor faults, lead to the necessity to identify the induction machine paramete...Show More
To remain competitive, the manufacturing industry is using computer processing power to innovate, develop and optimize new cost-efficient production strategies. This is the reason why optimization of automation systems is deployed to improve productivity, quality and robustness of the production. The different existing goals of optimization as the control machine, management of the power consumpti...Show More
To remain competitive, the manufacturing industry is always innovating and developing new cost-efficient ways to produce goods. That is why today, extensive automation is applied in nearly every type of manufacturing and assembly processes. Automation improves productivity, quality and robustness of products. It also increases the predictability of production lines mainly constituted of asynchrono...Show More
