9+ hour, 59+ min ago   (551+ words) Background: Volleyball court roles impose distinct physical demands, yet multi-domain position-specific profiles of elite female players are scarce. This study compared anthropometric characteristics and field-test physical performance across five positions. Methods: Fifty players (10 per position: setter, libero, outside hitter, opposite,…...

1+ day, 2+ hour 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…...

1+ day, 3+ hour ago   (495+ words) Steel storage tanks are erected on site by multi-cylinder hydraulic lifting, conventionally from one power unit feeding all cylinders through a flow divider. Decentralized alternatives have not been evaluated for this task, and modularity in fluid power is rarely quantified....

1+ day, 4+ hour ago   (543+ words) The Northeastern Donkey represents an important animal genetic resource adapted to the semi-arid conditions of Brazil, being recognized for its hardiness and ability to survive under challenging environmental conditions. However, the progressive reduction in the use of these animals in…...

1+ day, 6+ hour ago   (591+ words) During the frequent charging, discharging, and storage processes of underground compressed air energy storage systems, the damage and degradation of sealing plugs directly affect the long-term stability of gas storage caverns. Using a self-developed cyclic charging–storage–discharging–restorage gas…...

1+ day, 7+ hour ago   (538+ words) This study investigates how sentiment polarity relates to offensive function in Chinese online attacks, focusing on cases where offence is expressed implicitly rather than through explicit negative wording. Using a 1400-item Chinese online-text corpus derived from TOXICN and its pragmatics-oriented…...

1+ day, 7+ hour ago   (277+ words) Crop models are increasingly incorporated into web applications, but their user and programming interfaces are often developed separately from the model implementation. We extended Cropbox, a crop modeling framework written in Julia, to derive both interfaces from model declarations written…...

1+ day, 8+ hour ago   (460+ words) Marine hydraulic ramps exhibit pronounced nonlinear behavior arising from configuration-dependent transmission geometry, gravitational torque, and servovalve flow–pressure coupling. Accurate angle regulation is further complicated by external disturbances and unavailable internal states. This study develops a nonlinear extended state observer…...

2+ day, 6+ 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…...

2+ day, 7+ 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…...
