7+ hour, 53+ min ago   (347+ words) The delineation of mineralized zones within deposits is inherently associated with geological uncertainty, directly impacting resource-reserve estimation and eventual extraction. This study presents a comparative analysis of three geological modeling techniques, including Indicator Kriging (IK), Nearest Neighbor (NN), and Multilayer…...

9+ hour, 5+ 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....

9+ hour, 16+ min ago   (361+ words) This research investigates the security of large language models (LLMs) with the aim of identifying key security and safety threats, control measures, and governance considerations that are relevant to their trustworthy adoption in the Extended Reality (XR) domain. To achieve…...

11+ hour, 40+ min ago   (507+ words) Modern corporate networks operate in increasingly complex and heterogeneous environments, which complicates the objective assessment of their current security state. This study proposes a dual-channel multi-level model for quantitative assessment of data security in corporate networks using a predefined list…...

12+ hour, 52+ min ago   (678+ words) Mapless deep reinforcement learning (DRL) navigation in dynamic indoor environments is difficult under single-frame 2D LiDAR, which reports where an obstacle is but not whether it is approaching. We introduce the Positional-Velocity Spatio-Temporal Attention Module (PV-STAM), a compact perception block (19,968 trainable…...

13+ hour, 13+ min 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, 7+ hour ago   (567+ words) Individual cattle identification underpins traceability, genetic management and disease surveillance in precision livestock farming. Ear tags and RFID remain the dominant practice but are subject to loss, tampering and welfare concerns, which motivates contactless biometric alternatives. Most deep learning systems…...

1+ day, 8+ hour 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, 8+ hour ago   (497+ words) Research on educational virtual reality (VR) has focused on learning outcomes, but less on the design strategies that create those outcomes or whether benefits are consistent across different learners. This study created user experience (UX) design guidelines for educational VR…...

1+ day, 12+ hour ago   (394+ words) With the rapid development of wireless communication technologies, mobile devices, and distributed systems, the scale and dynamics of Mobile Ad Hoc Networks (MANETs) are increasing, which results in increasingly stringent requirements for routing protocols. The Zone Routing Protocol (ZRP), as…...
