An ErrorBased Approximation Sensing Circuit for EventTriggered LowPower Wearable Sensors
(20230424)Eventbased sensors have the potential to optimize energy consumption at every stage in the signal processing pipeline, including data acquisition, transmission, processing, and storage. However, almost all stateoftheart ... 
Diagnosis of the health status of mooring systems for floating offshore wind turbines using autoencoders
(20231101)Floating offshore wind turbines (FOWTs) show promise in terms of energy production, availability, and sustainability, but remain unprofitable due to high maintenance costs. This work proposes a deep learning algorithm to ... 
Predictive Maintenance of Floating Offshore Wind Turbine Mooring Lines using Deep Neural Networks
(2022)The recent massive deployment of onshore wind farms has caused controversy to arise mainly around the issues of land occupation, noise and visual pollution and impact on wildlife. Fixed offshore turbines, albeit beneficial ... 
Geometric Hermite interpolation by rational curves of constant width
(20230928)A constructive characterization of the support function for a rationally parameterized curve of constant width is given. In addition, a Hermite interpolation problem for such kind of curves is solved, which yields a method ... 
A Deep Fourier Residual Method for solving PDEs using Neural Networks
(2022)When using Neural Networks as trial functions to numerically solve PDEs, a key choice to be made is the loss function to be minimised, which should ideally correspond to a norm of the error. In multiple problems, this ... 
Cloud benchmarking and performance analysis of an HPC application in Amazon EC2
