A Review of Automatic Measurement of Learning Engagement Using Body Clues

Future in Educational Research, EarlyView.
ABSTRACT Learning engagement is an overarching multifaceted construct that includes behavioral, cognitive, and emotional dimensions. The static subjective measurements may lead to inaccurate results. Considering the authenticity and reliability of body signals, this study investigated the types of body cues used in measuring learning engagement and ...

Integrating Vehicle Slip and Yaw in Overarching Multi-Tiered Vehicle Steering Control to Balance Path Following Accuracy, Gracefulness, and Safety

Actuators
Balancing path-following accuracy and error convergence with graceful motion in steering control is challenging due to the competing nature of these requirements, especially across a range of operating speeds and conditions.

Plastic luminescence in mechanoluminescent composites

InfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

Do Linking‐Expression Substitutions Mitigate Deterministic Interpretations of Genetic Information?

Journal of Applied Philosophy, EarlyView.
ABSTRACT It is a common concern that broader audiences interpret scientific information about the genetic correlates and causes of complex human traits in an overly deterministic manner. A frequently proposed way to address this issue is to carefully select the linking expressions used to describe gene–trait relationships when communicating genetic ...

Approximate Reachability for Feedback Linearizable Systems

Optimal Control Applications and Methods, EarlyView.
The backwards reachable set for a dynamical system is the set of states for which there exists a constraint admissible trajectory that reaches a given terminal set. Conventional grid‐based approaches for computing these sets are intractable for many applications.
