This editorial is a commentary on the review paper by Ramirez Varela et al. entitled "Mapping the historical development of physical activity and health research: a structured literature review and citation network analysis." This editorial highlights the significance and implications of this review, with a particular focus on future research and policy directions. [ABSTRACT FROM AUTHOR]
The objective of this paper is to describe the modified Dahl and Masing models used for predicting hysteretic behavior, and tested on a belt tensioner for automotive engines. An experimental study with deflection imposed on the tensioner is first carried out to identify hysteresis loop parameters for the two models. The models are implemented in the general motion equations which govern the behavior of a belt–tensioner–mass system. Particular attention is paid to the use of numerical schemes. The numerical and experimental investigations show the reliability of the modified Dahl model. [Copyright &y& Elsevier]
