Untimely machinery breakdown will incur significant losses, especially to the manufacturing
company as it affects the production rates. During operation, machines generate vibrations …

Local wavenumber estimation (LWE) applied to a full wavefield response is a powerful
approach for detecting and characterizing defects in a composite structure. However, the …

This study presents a novel methodology for estimating the master curve of the complex
modulus of viscoelastic materials using a combination of optical measurement systems and …

In this study, we developed a real-time vibration visualization system that can estimate and
display vibration distributions at all frequencies in real time through parallel implementation …

This chapter reviews ultrasonic wavefield imaging techniques and their pivotal role in the
structural health monitoring (SHM) sector. The chapter begins with an introduction to contact …

We propose a novel material characterization method to estimate the Young's modulus of
thin 2-D structures using non-modal noisy single frequency harmonic vibration data …

Asphalt mixtures are the most common types of pavement material used in the world.
Characterizing the mechanical behavior of these complex materials is essential in durable …

Estimating the master curve of the complex modulus of asphalt mixtures is essential for high
quality and sustainable mixture and pavement design. There are multiple standard methods …

Bladed-disks in turbomachines experience high cycle fatigue failures due to high vibration
amplitudes. Therefore, it is important to accurately predict their dynamic characteristics …

Video is a huge source of information and the only way to extract that information is video
processing. Depending upon the information to be retrieved or analyzed, the video …
