9+ hour, 53+ min 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....

14+ hour, 28+ min ago   (259+ words) The dynamic response of soft terrain under repeated vehicle passes significantly influences off-road vehicle mobility and performance. The primary innovation of this research is the integration of loading–unloading hysteresis, multi-pass terrain-state evolution, and sensitivity analyses within a unified HSSTM-based…...

1+ day, 14+ 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, 15+ hour ago   (417+ words) Infrared thermal cameras are widely used for non-contact temperature measurement, but their indications are affected by measurement distance, temporal response, display resolution and scene stability. This paper presents an experimental evaluation of an infrared thermal camera using a blackbody reference…...

3+ day, 8+ 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…...

3+ day, 9+ 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....

4+ day, 9+ hour ago   (691+ words) This article examines the problem of assessing the reliability of stamped-welded freight car bogie components based on fatigue strength criteria under operational loads. The theoretical framework utilizes the principles of the linear fatigue damage summation hypothesis, the power-law fatigue curve,…...

4+ day, 17+ hour ago   (308+ words) Visual security quantification is critical for evaluating perceptual image encryption schemes. Traditional visual security indices often rely on partial feature extraction and fixed-position block matching, which limits their capability to capture localized information leakage. To address these limitations, this paper…...

5+ day, 9+ hour ago   (650+ words) Anomaly detection in industrial automated visual inspection (AVI) is constrained by severe data sparsity and class imbalance, as defect samples are both scarce and morphologically heterogeneous in real production environments. Existing context-aware synthesis frameworks, such as CASDA, alleviate this limitation…...

6+ day, 9+ hour ago   (586+ words) Accurate iris segmentation remains a fundamental challenge in iris biometric recognition and medical image analysis, particularly in challenging scenarios such as non-cooperative acquisition conditions involving variable illumination, partial occlusions, degraded image quality, and diverse unconstrained environments. Prevailing segmentation algorithms exhibit…...
