Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

Sedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope

Sedimentology, EarlyView.
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

RBF NN-Based Backstepping Adaptive Control for a Class of Nonlinear Systems

MATEC Web of Conferences, 2018
There are many control methods for nonlinear systems, but some of them can not control nonlinear mismatched systems very well. Backstepping control has obvious advantages in controlling nonlinear mismatched systems.

Quantifying Shuttlecock Skill Progression via Multimodal Action Recognition and Dynamics‐Guided Trajectory Prediction

Engineering Reports, Volume 8, Issue 10, October 2026.
This study proposes a multimodal feature fusion‐based action recognition and trajectory prediction framework to quantitatively evaluate the effectiveness of compensatory exercises in accelerating shuttlecock skill acquisition. The system comprehensively employs TrackNet, Faster R‐CNN, and HRNet to extract shuttlecock trajectories, player positions, and

Enhanced Control of 1.5 MW DFIG Generators in MRWT Systems Using GA‐Based PI‐ST‐SMC: Comparative Assessment With ST‐SMC

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT This paper proposes a novel genetic algorithm‐based proportional–integral super‐twisting sliding mode control (GA‐PI‐ST‐SMC) strategy for the rotor‐side converter of a 1.5 MW doubly‐fed induction generator (DFIG) operating in marine renewable wind turbine (MRWT) systems.
