4+ min ago   (538+ words) Source identification in confined underground ventilation systems is essential for hazardous-gas monitoring, and uranium-mine radon provides a representative case in which release locations and strengths must be inferred from limited concentration measurements. This presents an underdetermined, ill-posed inverse problem whose…...

16+ min ago   (509+ words) This study experimentally investigated the long-term deformation behavior of a ballasted railway turnout affected by adjacent deep excavation through an integrated multi-sensor field-monitoring approach. The monitored facility consisted of two 60 kg, #10 single turnouts located approximately 13 m from an excavation with…...

22+ min ago   (448+ words) Aquatic environments impose strong constraints on conventional feedback channels and challenge the deployment of wearable human–machine interfaces. This paper presents the design, characterization, and field validation of a head-worn vibrotactile interface intended for symbolic cue delivery during swimming. The…...

41+ min ago   (393+ words) To address the limitations of existing visual detection algorithms for mining wire ropes (MWR), including low detection accuracy, limited capability to recognize tiny defects, and high computational cost, we first employ NAFNet to mitigate motion blur in the input images....

52+ min ago   (667+ words) Localized groundwater leakage through retaining and cutoff systems can reorganize hydraulic gradients and trigger deformation that is difficult to distinguish from the normal response to excavation and dewatering. This study tests whether spatial deformation residuals, interpreted with transient hydro-mechanical modeling,…...

54+ min ago   (107+ words) Accurate hygrothermal characterization and robust numerical modeling are critical for optimizing timber drying processes and evaluating building envelope performance. This work presents a 1D transient numerical model based on the finite volume method (FVM) and a representative elementary volume (REV) formulation…...

1+ hour, 7+ min ago   (361+ words) Multi-camera vehicle sensing provides a cost-effective solution for 3D environmental perception in intelligent vehicles. A practical challenge is that temporal fusion becomes unreliable when the ego-vehicle undergoes aggressive motion. Historical camera features are commonly aligned by rigid ego-pose warping, but residual…...

1+ hour, 48+ min ago   (382+ words) Mining and metallurgical wastes contain reactive Fe-, Al-, Ca-, Mg-, and Mn-bearing phases. These phases can be used for water treatment. Their performance depends on mineral accessibility, processing history, and water chemistry rather than waste identity alone. This review compares…...

2+ hour, 13+ min ago   (400+ words) This study investigates how asphalt layer structural combinations affect the internal mechanical response and rutting development of asphalt pavements on long steep grades. A three-dimensional Abaqus finite element model was developed for a typical semi-rigid base asphalt pavement used on…...

2+ hour, 21+ min ago   (396+ words) Underwater object detection is a core technology for environmental perception and autonomous operation of unmanned underwater vehicles (UUVs). However, optical and acoustic sensing alone suffer from physical limitations, leading to missed and false detections in turbid, low-light, or long-range conditions....
