Understanding Personality through Patterns of Daily Socializing: Applying Recurrence Quantification Analysis (RQA) to Naturalistically Observed Intensive Longitudinal Social Interaction Data

open access: yesEuropean Journal of Personality, 2020
Ambulatory assessment methods provide a rich approach for studying daily behavior. Too often, however, these data are analyzed in terms of averages, neglecting patterning of this behavior over time. This paper describes Recurrence Quantification Analysis (RQA), a non-linear time series technique for analyzing dynamic systems, as a method for analyzing ...

A Nonlinear Method for Characterizing Discrete Defects in Thick Multilayer Composites

open access: yesApplied Sciences, 2019
Discrete defects in thick composites are difficult to detect for the small size and the structure noise that appears in multilayer composites. In this paper, a nonlinear method, called recurrence analysis, has been used for characterizing discrete ...
