VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

Advanced Intelligent Systems, EarlyView.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...

An analysis of the benefits of signal injection for low-speed sensorless control of induction motors

, 2015
We analyze why low-speed sensorless control of the IM is intrinsically difficult, and what is gained by signal injection. The explanation relies on the control-theoretic concept of observability applied to a general model of the saturated IM.

EMG‐Driven Telemetry and Inference System for Fish: Pose Reconstruction and Flow Sensing

Advanced Intelligent Systems, EarlyView.
This work introduces an electromyography (EMG)‐driven telemetry framework that reconstructs body pose and infers hydrodynamic conditions in freely swimming fish. A custom 16‐channel archival system records intramuscular EMG, enabling deep‐learning models to decode joint kinematics, classify flow regimes, and reveal channel‐efficient sensing strategies.

Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

Deep Underground Science and Engineering, EarlyView.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.
