Predictive Fault Tolerance for Autonomous Robot Swarms [PDF]
arXiv, 2023 Active fault tolerance is essential for robot swarms to retain long-term autonomy. Previous work on swarm fault tolerance focuses on reacting to electro-mechanical faults that are spontaneously injected into robot sensors and actuators. Resolving faults once they have manifested as failures is an inefficient approach, and there are some safety-critical

Seismicity relocation and fault structure near the Leech River Fault Zone, southern Vancouver Island [PDF]
, 2018 Relatively low rates of seismicity and fault loading have made it challenging to correlate microseismicity to mapped surface faults on the forearc of southern Vancouver Island.

Earthquake Probability Assessment for the Active Faults in Central Taiwan: A Case Study
Terrestrial, Atmospheric and Oceanic Sciences, 2016 Frequent high seismic activities occur in Taiwan due to fast plate motions. According to the historical records the most destructive earthquakes in Taiwan were caused mainly by inland active faults.

ACTIVE FAULTS AND CHARACTERIZATION IN OSAKA AND ALMATY BY BORING DATA BASE
Architecture and Engineering, 2018 The active fault in Osaka is known as Uemachi fault, which had been originally identified as geomorphological feature of the Osaka high terrace. However, the position of the fault line was corrected by geotechnical information during subway construction.

Dynamics, radiation and overall energy budget of earthquake rupture with coseismic off-fault damage [PDF]
, 2019 Earthquake ruptures dynamically activate coseismic off-fault damage around fault cores. Systematic field observation efforts have shown the distribution of off-fault damage around main faults, while numerical modeling using elastic-plastic off-fault material models has demonstrated the evolution of coseismic off-fault damage during earthquake ruptures.

Fault Detection and Identification - a Filter Investigation [PDF]
International Journal of Robust and Nonlinear Control 28 (2017)
1852-1870, 2016 This paper develops a new active fault tolerant control system based on the concept of analytical redundancy. The novel design consists of an observation filter based fault detection and identification system integrated with a nonlinear model predictive controller.

Millennial slip rate of the Longitudinal Valley fault from river terraces: Implications for convergence across the active suture of eastern Taiwan [PDF]
, 2006 The Longitudinal Valley fault is a key element in the active tectonics of Taiwan. It is the principal structure accommodating convergence across one of the two active sutures of the Taiwan orogeny.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions
FEBS Letters, EarlyView.This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...
