9+ hour, 41+ min ago   (409+ words) Wall thinning caused by corrosion changes the circumferential strain response of storage tanks, but nonlinear coupling among structural parameters, loading conditions, strain characteristics, and defect geometry makes direct inversion difficult. This paper develops a strain-based, finite element (FE)-based machine…...

13+ hour, 18+ min ago   (296+ words) Museums face a conflict between energy-efficient gallery lighting and protecting light-sensitive collections from photochemical damage: increasing the luminous efficacy of white LEDs requires shifting spectral power toward the high-energy blue band, accelerating degradation of organic materials. Prior work treated these…...

1+ day, 12+ hour ago   (526+ words) This study provides a computational and experimental assessment of the parametric reliability of friction pairs in brake devices for lifting and transport technology. The computational and experimental method for assessing the parametric reliability of various friction units in lifting and…...

1+ day, 14+ hour ago   (502+ words) Partial discharge (PD) generates transient acoustic-vibration signals that can be used for the passive monitoring of cable insulation. Unlike previous studies that separately addressed DFB-FL sensitivity, polymer-property effects, or acoustic attenuation in a particular cable, this study establishes an application-oriented…...

1+ day, 14+ hour ago   (506+ words) This study presents SenseMat, a modular sensing infrastructure based on recycled end-of-life tire (ELT)-derived rubber flooring that integrates continuous body-weight (BW) estimation, environmental monitoring and Internet-of-Things (IoT) connectivity into a single structural livestock infrastructure. Designed as a modular engineering…...

1+ day, 15+ hour ago   (558+ words) This study presents an integrated green analytical strategy combining deep eutectic solvent (DES) screening, Fourier transform infrared spectroscopy (FTIR), principal component analysis (PCA), and Box–Behnken response surface optimization for the valorization of pineapple crowns, an underexplored agro-industrial by-product. An…...

3+ day, 8+ hour ago   (468+ words) The rubber cylinder is the core sealing element of a compression packer, and its structural stability directly determines downhole sealing reliability. The rubber cylinder is made of HNBR, while the central tube, support rings, and casing are made of 35 CrMo…...

3+ day, 10+ hour ago   (459+ words) Electrostatic discharge (ESD) in fluoropolymer-lined Standard Clean-1 (SC-1) delivery systems is a reliability concern in semiconductor wet processing, yet its physicochemical pathway remains uncertain. This field-based study investigated ESD-damaged perfluoroalkoxy alkane (PFA)- and polytetrafluoroethylene (PTFE)-lined components using operational observations,…...

3+ day, 11+ hour ago   (329+ words) Annular fillet welds on guide rods lie in stress concentration zones and are susceptible to fatigue failure under dynamic suspension loads, necessitating accurate quality inspection. However, their complex three-dimensional topography makes it difficult for conventional methods to balance detection accuracy…...

3+ day, 13+ hour ago   (525+ words) Seismic pier-top pounding in high-speed railway bridges transfers short-duration girder-restraint contact forces into bridge piers, coupling local contact damage with global vibration and possible base yielding. This critical review evaluates how evidence and modelling strategies can be transferred from local…...
