32+ min ago   (596+ words) Multi-station global navigation satellite system (GNSS) displacement-residual forecasting may benefit from neighbouring stations, yet unrestricted spatial aggregation can obscure station-local temporal dynamics and the independent value of spatial information. Whether neighbouring stations provide additional predictive information after a strong station-local…...

45+ 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+ hour, 10+ min 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…...

20+ hour, 41+ min ago   (512+ words) REBA, RULA, and OWAS are widely used observational ergonomic risk assessment methods based on predefined ordinal scoring rules. The final risk scores generated by these methods play a critical role in determining and prioritizing ergonomic interventions under limited resources to…...

1+ day, 1+ hour ago   (394+ words) This paper investigates the thermal characteristics of machine tools under the influence of multiple heat sources and proposes an active temperature control method. The study was conducted under steady-state conditions with a constant feed rate of 10 m/min and no…...

1+ day, 2+ hour ago   (478+ words) Digital risk communication increasingly relies on interactive technologies to transform complex, uncertain, and probabilistic information into forms that can support human understanding and decision-making. Yet the literature is fragmented across application domains, technologies, and interaction paradigms. This scoping review maps…...

2+ day, 19+ hour ago   (415+ words) Multi-product production systems require effective coordination among production, intermediate storage, downstream processing, and customer demand, particularly under stochastic operating conditions and finite capacity. Unlike existing analytical studies that mainly examine either single-product push–pull systems or multi-product manufacturing systems separately,…...

2+ day, 20+ hour ago   (688+ words) Digital twins (DTs) based on agent-based artificial intelligence (Agentic AI) provide a transformative framework for streamlining nondestructive testing (NDT) of 3D-printed rehabilitation equipment. This study applies a conceptual research methodology based on the integration and analysis of recent advances in…...

2+ day, 21+ hour ago   (186+ words) This study investigates a sustainable vehicle-routing problem in which a heterogeneous fleet serves geographically dispersed customer demands from a central distribution facility. The problem simultaneously minimizes transportation costs and CO2 emissions, with deliveries performed by either in-house or externally rented vehicles....

3+ day, 1+ hour ago   (524+ words) A piezoelectric cantilever with a longitudinal slit splits one bending resonance into two closely spaced peaks. This is attractive for two-frequency sources. However, existing models fit, rather than predict, the resonances. We develop a predictive branched-beam model where the harvester…...
