The sinusoidal crack

Crack

Crack: The tests were performed using Crack version 1.0 beta 18. Crack is a description logic system with both TBox and ABox, using the logic ALCRIFO. Crack reasoning procedures are based on a sound and complete tableaux algorithm 1].

Sinusoidal Modelling

The Manipulative Crack

OBJECTIVES This research was designed to analyse the frequency spectra of joint crack sounds produced during spinal manipulative therapy applied to the upper cervical spine of 50 volunteers and to determine if the spectra differed between the sexes and or for those with a history of previous neck trauma compared with those without a history of trauma. DESIGN Randomised experimental study. S...

Crack Linkup by Stable Crack Growth

Experimentally determined T ε and CTOA resistance curves were used to simulate numerically, stable crack growth and the ensuing crack linkup in 0.8 mm thick 2024-T3 aluminum tension specimen with multiple site damage (MSD) subjected to monotonically/cyclically increasing loading. The T ε integral correctly predicted the crack growth and linkup history as well as the onset of rapid fracture in M...

Signal Characterization in terms of Sinusoidal and Non-Sinusoidal Components

This paper addresses the problem of signal characterization in terms of sinusoidal and non-sinusoidal components. A first measure of sinusoidality is reviewed. Drawbacks of this sinusoidal estimator are investigated and solutions proposed. Estimation of sinusoidality on non-stationary signal is then made on a pre-processed signal. A phase derived sinusoidality measure and the use of Re-estimate...
