Enhancing Knowledge Management in Green Building Engineering: A Hybrid Retrieval-Augmented Generation Approach to Support Project Assessment

Abstract Green building assessment relies heavily on manual queries of complex engineering regulations, making the introduction of knowledge management theories crucial for improving assessment efficiency. However, the inherent characteristics of engineering regulations—dense ter...

Substructural shake table tests examining the seismic performance of point-supported glass facades

This paper aims to investigate the seismic performance of the coupled system comprising a large-span spatial structure and point-supported glass facades (PSGFs) through substructural shake table tests. A two-story substructure testbed is proposed to replicate the target responses...

Promoting Effects of CuSO4 Modification on N2 Selectivity of 1Ru/5Ce-TiO2 Catalyst for Selective Catalytic Oxidation of NH3

Abstract xCu+1Ru/5Ce-TiO2 catalysts were prepared by a grinding method to improve the NH3–SCO performance of 1Ru/5Ce-TiO2. The results revealed a marked promotion of N2 selectivity over 1Ru/5Ce-TiO2 upon CuSO4 incorporation. In particular, the 5Cu+1Ru/5Ce-TiO2 catalyst exhibited...

Tension–Compression Fatigue Behaviour of Jacket Grouted Connections with Different Grout Strengths

Grouted connections are widely used in offshore jacket structures and are often subjected to eccentric compression and tension–compression cyclic loading arising from installation deviations and environmental actions. This study presents a comparative investigation of the fatigue...

Multicomponent Seismic Data Denoising and Reconstruction with Fast Quaternion Curvelet Transform

Abstract In the field of multicomponent (MC) seismic data, vector processing has become an important research trend. Unlike conventional scalar approaches that handle each component individually, vector approaches can exploit the inner relationship among different components to a...

Pore and mineral controls on petrophysical anomalies in undercompacted mudstones

Abstract In mudstones, undercompaction inhibits grain rearrangement, preserving pores and generating anomalous petrophysical responses. These anomalies typically manifest in geophysical exploration as abnormal acoustic and resistivity logs. However, the microstructural difference...
