Bearing Degradation Evaluation Using Improved Cross Recurrence Quantification Analysis and Nonlinear Auto-Regressive Neural Network [PDF]
IEEE Access, 2019 This paper presents an improved cross recurrence quantitative analysis (CRQA) method for bearing degradation evaluation. It extracts CRQA variable from bearings' vibration signals to establish the degradation trend.

Gaze collaboration patterns of successful and unsuccessful programming pairs using cross-recurrence quantification analysis [PDF]
Research and Practice in Technology Enhanced Learning, 2019 A dual eye tracking experiment was performed on pairs of novice programmers as they traced and debugged fragments of code. These programming pairs were categorized into successful and unsuccessful pairs based on their debugging scores.

Measuring Coupling of Rhythmical Time Series Using Cross Sample Entropy and Cross Recurrence Quantification Analysis. [PDF]
Comput Math Methods Med, 2017 The aim of this investigation was to compare and contrast the use of cross sample entropy (xSE) and cross recurrence quantification analysis (cRQA) measures for the assessment of coupling of rhythmical patterns. Measures were assessed using simulated signals with regular, chaotic, and random fluctuations in frequency, amplitude, and a combination of ...

Cross recurrence quantification analysis of precision grip following peripheral median nerve block. [PDF]
J Neuroeng Rehabil, 2013 Precision grip by the thumb and index finger is vulnerable to sensorimotor deficits. Traditional biomechanical parameters offer limited insight into the dynamical coordination between digits during precision grip. In this study, the thumb and index finger were viewed as "coupled systems", and a cross recurrence quantification analysis (CRQA) was used ...

APSIPA Transactions on Signal and Information Processing, 2022 Pair programming is a model of collaborative learning. It has become a well-known pedagogical practice in teaching introductory programming courses because of its potential benefits to students. This study aims to investigate pair patterns in the context of pair program tracing and debugging to determine what characterizes collaboration and how these ...

Online social cohesion reflects real-world group action in Syria during the Arab Spring.
PLoS ONE, 2021 In recent years, political activists have taken to social media platforms to rapidly reach broad audiences. Despite the prevalence of micro-blogging in these sociopolitical movements, the degree to which virtual mobilization reflects or drives real-world
