Digital documentation of railway tunnel inspection in Austria
Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Rock Mass Anomaly Detection with a Variational Autoencoder in Tunnel Boring Machine Data
Civil Engineering Design, EarlyView.Abstract This study presents an unsupervised machine learning approach to rock mass anomaly detection in tunnel boring machine operational data using a Variational Autoencoder combined with bidirectional Long Short‐Term Memory cells. The model was trained on TBM data from the Brenner Base Tunnel project, with minor faults and geotechnically relevant ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Physiographic Features of Faulting in Southern California [PDF]
, 1954 The abundance and variety of faults in southern California provide good opportunity for study of landforms created directly by faulting or indirectly by other processes acting upon faulted materials. High-angle gravity faults, high- and low-angle thrusts,

Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas
The Depositional Record, EarlyView.Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.

The Depositional Record, EarlyView.We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

Polygonal tepee structures of Arabia
The Depositional Record, EarlyView.Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...
