An Anomaly Detection Method for Sliding Bearings Under Electromagnetic Interference Based on an Asymmetric Autoencoder and a Dual-Indicator Diagnostic Plane

Machines
As core components of marine power systems, sliding bearings directly affect the operational safety of ships. To address the challenges that early weak anomaly features of sliding bearings are easily masked by electromagnetic interference (EMI) and that ...

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

Development of a Cold Wall Reactor System for the Low‐Pressure Chemical Vapor Deposition of BN on SiC Fiber Tow

Advanced Engineering Materials, EarlyView.
A cold wall reactor is developed to coat a SiC fiber tow with BN by low pressure chemical vapor deposition. The precursor gas is triethylamine borane mixed with ammonia. The heating process induces a temperature gradient, with the temperature decreasing from the core to the surface of the multifilament tow.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Quasi-Sliding Mode Control of Discrete-Time Systems [PDF]

, 1999
A reaching law approach to the design of discrete-time quasi-sliding mode control systems is considered. First the required position of the system representative point with reference to the sliding plane is specified, and then novel control strategies ...

Study on Directional Shear Creep Characteristics of Rock Mass Controlled by Structural Plane

工程科学与技术
ObjectiveLong-term creep deformation of a slope is significant for major engineering practice and the natural environment. A high and steep rock slope located in a high tectonic stress area can creep due to the elevated stress level of the slope.
