REAL TIME DATA ACQUISITION AND MONITORING OF PATIENTS WITH CORONARY HEART DISEASE IN A HOME ENVIRONMENT
The high mortality rate associated with cardiovascular related diseases requires the implementation of a personalised, ubiquitous health monitoring system. With the recent advancements of wireless sensor network technologies, these study proposes a real time data acquisition and monitoring system for patients with a track history of coronary heart diseases based on the implementation of a microcontroller, GSM Module and temperature sensors. This pervasive healthcare system will provide a round the clock monitoring and has an in built alerting mechanism for detecting anomalies in cardiac activities. The aim of the study is to minimize the need for caretakers and help the gravely ill senior citizens to survive an independent life. Apart from that, this study will help reduce the mortality rate of victim by shortening the response time of medical team to the victims. In these study, the proposed design mechanism will consider the following key criteria namely safety, data security, energy efficiency, durability and cost incurred
ECG denoising based on adaptive signal processing technique
An Electrocardiogram (ECG) monitoring system deals with several challenges related
with noise sources. The main goal of this text was the study of Adaptive
Signal Processing Algorithms for ECG noise reduction when applied to real signals.
This document presents an adaptive ltering technique based on Least Mean Square
(LMS) algorithm to remove the artefacts caused by electromyography (EMG) and
power line noise into ECG signal. For this experiments it was used real noise signals,
mainly to observe the di erence between real noise and simulated noise sources. It
was obtained very good results due to the ability of noise removing that can be
reached with this technique.

Advanced sensors technology survey
This project assesses the state-of-the-art in advanced or 'smart' sensors technology for NASA Life Sciences research applications with an emphasis on those sensors with potential applications on the space station freedom (SSF). The objectives are: (1) to conduct literature reviews on relevant advanced sensor technology; (2) to interview various scientists and engineers in industry, academia, and government who are knowledgeable on this topic; (3) to provide viewpoints and opinions regarding the potential applications of this technology on the SSF; and (4) to provide summary charts of relevant technologies and centers where these technologies are being developed
Seamless Multimodal Biometrics for Continuous Personalised Wellbeing Monitoring
Artificially intelligent perception is increasingly present in the lives of
every one of us. Vehicles are no exception, (...) In the near future, pattern
recognition will have an even stronger role in vehicles, as self-driving cars
will require automated ways to understand what is happening around (and within)
them and act accordingly. (...) This doctoral work focused on advancing
in-vehicle sensing through the research of novel computer vision and pattern
recognition methodologies for both biometrics and wellbeing monitoring. The
main focus has been on electrocardiogram (ECG) biometrics, a trait well-known
for its potential for seamless driver monitoring. Major efforts were devoted to
achieving improved performance in identification and identity verification in
off-the-person scenarios, well-known for increased noise and variability. Here,
end-to-end deep learning ECG biometric solutions were proposed and important
topics were addressed such as cross-database and long-term performance,
waveform relevance through explainability, and interlead conversion. Face
biometrics, a natural complement to the ECG in seamless unconstrained
scenarios, was also studied in this work. The open challenges of masked face
recognition and interpretability in biometrics were tackled in an effort to
evolve towards algorithms that are more transparent, trustworthy, and robust to
significant occlusions. Within the topic of wellbeing monitoring, improved
solutions to multimodal emotion recognition in groups of people and
activity/violence recognition in in-vehicle scenarios were proposed. At last,
we also proposed a novel way to learn template security within end-to-end
models, dismissing additional separate encryption processes, and a
self-supervised learning approach tailored to sequential data, in order to
ensure data security and optimal performance. (...)Comment: Doctoral thesis presented and approved on the 21st of December 2022

Affective Computing
This book provides an overview of state of the art research in Affective Computing. It presents new ideas, original results and practical experiences in this increasingly important research field. The book consists of 23 chapters categorized into four sections. Since one of the most important means of human communication is facial expression, the first section of this book (Chapters 1 to 7) presents a research on synthesis and recognition of facial expressions. Given that we not only use the face but also body movements to express ourselves, in the second section (Chapters 8 to 11) we present a research on perception and generation of emotional expressions by using full-body motions. The third section of the book (Chapters 12 to 16) presents computational models on emotion, as well as findings from neuroscience research. In the last section of the book (Chapters 17 to 22) we present applications related to affective computing
