A State-Dependent Fragility Framework for Seismically Isolated Reinforced Concrete Bridges under Sequential Earthquake Loading

This study proposes a state-dependent performance-based framework using OpenSeesPy to assess the seismic fragility of seismically isolated reinforced concrete bridges under sequential earthquake loading, revealing that cumulative damage and residual deformations significantly degrade structural capacity compared to conventional undamaged-state assumptions.

Experimental Investigation on Machining of Aluminium Alloy (AA6041) using Response Surface Method for Optimal Surface Roughness, Cutting Temperature and Cutting Force

This study utilizes the Taguchi method and Response Surface Methodology to optimize dry end-milling parameters for AA6041 aluminium alloy, identifying feed rate, depth of cut, and cutting speed as key factors that minimize surface roughness, cutting temperature, and cutting force with high predictive accuracy.

Mechanical Integrity of Steel-Lined CAES Shafts under Internal Air Pressure: Concrete Tensile Yielding and Liner Configuration Assessment

This study utilizes FLAC3D modeling to demonstrate that increasing the thickness of the concrete annulus while reducing the steel liner radius in deep CAES shafts effectively limits tensile yielding propagation, thereby preserving the structural continuity and pressure-tightness of the barrier system under internal air pressure.

Stereological Validation and Statistical Framework for Pore Morphology in Aluminum-Aerated Dense Concrete

This study establishes the statistical and stereological validity of using 2D digital image analysis to characterize aluminum-aerated dense concrete by confirming that orthogonal sections reliably represent 3D pore populations and that spatial randomness holds, while demonstrating that pore morphology strongly predicts compressive and flexural strength but fails to explain splitting tensile strength due to its discrete critical-pore failure mechanism.

Human-Centered Decision Support for Flight Dispatch: A Scoping Review of Automation Bias, Workload, Situational Awareness, and AI-Assisted Airline Operations

This scoping review synthesizes evidence from flight dispatch, adjacent aviation, and general human–automation research to argue that AI-assisted flight dispatch should prioritize human authority and transparent support for uncertain, safety-critical decisions over maximum automation, proposing a new Human-Centered AI framework to mitigate risks like automation bias and situational awareness loss.

Optimization of Milling Tool Geometry for CFRP/Nomex Honeycomb Sandwich Structures Based on Side-Milling Experiments

This study optimizes milling tool geometry for CFRP/Nomex honeycomb sandwich structures through comparative experiments, revealing that while the T1 tool offers better heat dissipation, the T2 tool with a crescent-shaped chip-breaking groove provides superior overall performance characterized by reduced wear and stable cutting forces, which are intrinsically linked to the honeycomb's periodic cellular structure.

Direct Damping-Dependent Vertical Ground Motion Model for Stiff Soils in Active Crustal Regions

This paper proposes and validates a direct ground-motion prediction model for estimating vertical pseudo-acceleration response spectra across a range of damping ratios (1–20%) on stiff soils in active crustal regions, demonstrating that while it yields comparable variability to indirect scaling methods, it produces distinct median estimates that vary with earthquake magnitude.

Stability Assessment and Development of Stability Charts for Room and Pillar Mine Workings

This study utilizes numerical modeling to assess the stability of room and pillar mine workings under varying rock mass conditions, determining that filling is essential for GSI values of 40 or below and subsequently developing two stability charts to guide support system decisions and safe access through mined-out panels.
