Asynchronous Motor Bearing Fault Detection Methods
, 2011 Bearing, asynchronous deep groove ball bearings are widely used in induction motor field. Motor bearing failure probability is as high as 40% in asynchronous motor. It accounts for the largest proportion of failures in the motor.

Advanced Science, EarlyView.Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Mechanical Characteristics of Linear Asynchronous Motor
Elektronika ir Elektrotechnika, 2011 This work is concerned with the computations of the active forces in a unilateral linear asynchronous motor (LAM) without an inverse magnetic circuit, for both magnetic and unmagnetic moving bodies. Field and force computations were conducted and results analyzed. 1ll. 3, bibl.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue
Advanced Science, EarlyView.This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Research of Expert System of Fault Diagnosis for Asynchronous Motor Based on Neural Network
Gong-kuang zidonghua, 2010 In order to solve the problem that traditional expert system got knowledge hardly and connot solve new faults when diagnosing faults of asynchronous motor, the paper proposed a design scheme of expert system of fault diagnosis for asynchronous motor ...

Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Neuromorphic Devices and Computing for Sensing, Memory, and Control
Advanced Science, EarlyView.This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.
