KAUST researchers have developed a detailed 3D dynamic model using data from the February 2023 Turkiye earthquake to improve earthquake simulations. The model incorporates 3D fault geometry and Earth structure for realistic simulations of ground shaking. It explains complex ground shaking patterns and the impact of supershear ruptures, which can amplify damage far from the epicenter. Why it matters: This research provides a more accurate understanding of earthquake rupture processes, crucial for seismic hazard assessment and infrastructure planning in seismically active regions like the Middle East.
The study introduces the Qatar University Dual-Machine Bearing Fault Benchmark dataset (QU-DMBF) containing sound and vibration data from two motors across 1080 conditions. It proposes a deep learning approach for sound-based fault detection, addressing limitations of vibration-based methods. Experiments on QU-DMBF show sound-based detection is more robust, independent of sensor location, and cost-effective while matching vibration-based performance. Why it matters: The new dataset and findings could shift the focus toward sound-based methods for more reliable and accessible predictive maintenance in industrial settings.
Cristofaro Mune and Niek Timmers presented a seminar on bypassing unbreakable crypto using fault injection on Espressif ESP32 chips. The presentation detailed how the hardware-based Encrypted Secure Boot implementation of the ESP32 SoC was bypassed using a single EM glitch, without knowing the decryption key. This attack exploited multiple hardware vulnerabilities, enabling arbitrary code execution and extraction of plain-text data from external flash. Why it matters: The research highlights critical security vulnerabilities in embedded systems and the potential for fault injection attacks to bypass secure boot mechanisms, necessitating stronger hardware-level security measures.
Geophysicists at KAUST are investigating the "doublet" earthquake phenomenon in Turkey, where two strong earthquakes of magnitude 7.8 and 7.7 occurred within nine hours of each other on separate faults. Researchers from the Crustal Deformation and InSAR Group and the Computational Earthquake Seismology research group are using satellite and seismic data to examine the earthquake rupture process. The National Center for Earthquake and Volcano monitoring (NCEV) of the Saudi Geological Survey contributes seismic recordings to the KAUST teams. Why it matters: Understanding such earthquake doublets is crucial for improving seismic hazard assessment and risk mitigation in the region and globally.
Yuan-Kai Liu, a master’s student from KAUST, received the Outstanding Student Poster and PICO Award at the European Geosciences Union General Assembly 2017 for his poster on caldera ring-fault development. Liu's poster presented results from analogue experiments, including deformation characteristics from time-resolved digital image correlation and 3-D spatial photogrammetry data. His research focuses on ground deformation analyses of subsiding calderas, combining analogue experiments with numerical modeling. Why it matters: This award recognizes KAUST's contribution to earth science and engineering and highlights the university's focus on innovative research in geophysics.
