TL;DR: In this article, a finite-element model was developed to study the prediction accuracy for the modeling of carburized-quenched helical gear, which incorporates phase transformation kinetics during heating, carburizing, diffusing and quenching process.

TL;DR: In this paper, a new approach to the control strategies is implemented through interpreting the DCT powertrain as an over-actuated system that possesses actuator redundancy, and a new control structure is divided into two stages: the upper level control that governs the procedure to determine the most suitable torque trajectories of the clutches and engine, and the lower level controller that manages the strategy for each actuator controller to track the given torque trajectory.

TL;DR: A control-oriented model with practical concerns is implemented for DCT drivelines, aiming to accurately describe the powertrain oscillations that should be suppressed by the torque control, and a real-time torque monitoring strategy based on the proposed model is suggested to deal with the absence of torque sensors.

TL;DR: A new shift control strategy based on the feedback of both speed and torque states is implemented to improve the shift quality and a robust multivariable control scheme using H-infinity loop shaping is suggested, especially for the inertia phase control.

TL;DR: Evidence is found for a complexity barrier whereby editors are less likely to edit complex content in a second language and multilinguals are less engaged and show lower levels of language proficiency in their second languages.
