Structural Health Monitoring Using Ultrasonic Guided-Waves and the Degree of Health Index
(MDPI, 2021-02-02)
This paper proposes a new damage index named degree of health (DoH) to efficiently tackle structural damage monitoring in real-time. As a key contribution, the proposed index relies on a pattern matching methodology that ...
An Empirical Study on Transmission Beamforming for Ultrasonic Guided-Wave Based Structural Health Monitoring
(MDPI, 2020-03-06)
The development of reliable structural health monitoring techniques is enabling a healthy transition from preventive to condition-based maintenance, hence leading to safer and more efficient operation of different industries. ...
Ultrasonic Guided Wave Testing on Cross-Ply Composite Laminate: An Empirical Study
(MDPI, 2020-09-16)
Structural health monitoring comprises a set of techniques to detect defects appearing in structures. One of the most viable techniques is based on the guided ultrasonic wave test (UGWT), which consists of emitting waves ...
Reliable Control Applications with Wireless Communication Technologies: Application to Robotic Systems
(MDPI, 2021-10-26)
The nature of wireless propagation may reduce the QoS of the applications, such that some packages can be delayed or lost. For this reason, the design of wireless control applications must be faced in a holistic way to ...
Building IoT Applications with Raspberry Pi and Low Power IQRF Communication Modules
(MDPI, 2016-09)
Typical Internet of Things (IoT) applications involve collecting information automatically from diverse geographically-distributed smart sensors and concentrating the information into more powerful computers. The Raspberry ...
Scalable IoT Architecture for Monitoring IEQ Conditions in Public and Private Buildings
(MDPI, 2022-03-21)
This paper presents a scalable IoT architecture based on the edge–fog–cloud paradigm for monitoring the Indoor Environmental Quality (IEQ) parameters in public buildings. Nowadays, IEQ monitoring systems are becoming ...
An Architecture for On-Line Measurement of the Tip Clearance and Time of Arrival of a Bladed Disk of an Aircraft Engine
(MDPI, 2017-10)
Safety and performance of the turbo-engine in an aircraft is directly affected by the health of its blades. In recent years, several improvements to the sensors have taken place to monitor the blades in a non-intrusive ...
Encryption AXI Transaction Core for Enhanced FPGA Security
(MDPI, 2022-10-18)
The current hot topic in cyber-security is not constrained to software layers. As attacks on electronic circuits have become more usual and dangerous, hardening digital System-on-Chips has become crucial. This article ...
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
(Springer, 2020-10)
Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ...
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
(MDPI, 2018-07)
Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ...
