Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Pressure‐Decay Kinetic Modeling of Homogeneous Ethylene Polymerization with Et(Ind)2ZrCl2/TIBA‐Borate Catalyst System in a Batch Reactor

Polymer Engineering &Science, EarlyView.
A kinetic model comprising both propagation and deactivation functions was developed for metallocene‐catalyzed ethylene polymerization in a batch reactor. The model predicted polymer yields very close to the experimental ones. The polymer molecular weight increased with ethylene pressure and decreased with temperature.

Strategic Design Choices in Upcycled Fashion: Effects of Design Typicality and Material Domain Distance on Sustainable Consumption

Sustainable Development, EarlyView.
ABSTRACT While upcycling clothing reflects environmental value (i.e., greenness) and distinctive designs (i.e., uniqueness), consumer responses to upcycled clothing designs remain underexplored. Drawing on categorization, cue utilization, and domain distance theories, two experimental studies were conducted with US female aged 18–45.

Topology‐Encoded Charge Polarity Governs Multiphase Organization in Intrinsically Disordered Protein Polymer Condensates

Small, EarlyView.
Electrostatic topology is shown to program phase separation and internal organization in thermoresponsive intrinsically disordered protein polymer (IDPP) condensates. By comparing oppositely charged IDPPs with a covalent diblock, chain connectivity is revealed to control charge compensation, dense‐phase micropolarity, miscibility, and apparent acid ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
