Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Attentional Dynamics During Emotional Face Processing Differentiate Alexithymia From Mood and Affective Symptoms

Journal of Personality, EarlyView.
ABSTRACT Introduction Alexithymia refers to difficulties in experiencing and expressing emotions, differentiating them from bodily sensations, restricted imagination, and externally oriented thinking. Mood and affective symptoms are often confounded with alexithymia due to the typical assessment through self‐report.

A Cascade of Boosted Generative and Discriminative Classifiers for Vehicle Detection

EURASIP Journal on Advances in Signal Processing, 2008
We present an algorithm for the on-board vision vehicle detection problem using a cascade of boosted classifiers. Three families of features are compared: the rectangular filters (Haar-like features), the histograms of oriented gradient (HoG), and their ...
