Fault Self-Diagnosis for Modular Robotic Systems Using M-Lattice Modules
International Journal of Advanced Robotic Systems, 2015 In the domain of modular robotic systems, self-configuration, self-diagnosis and self-repair are known to be highly challenging tasks. This paper presents a novel fault self-diagnosis strategy which consists of two parts: fault detection and fault ...

Consensus-Based Method for Anomaly Detection in VAV Units
Energies, 2019 Buildings account for large part of global energy consumption. Besides energy consumed due to normal operation, a large amount of energy can be wasted due to faults in buildings subsystems.

Fault Detection and Diagnosis Based on Extensions of PCA
Advances in Military Technology, 2013 The paper presents two approaches for fault detection and discrimination based on extensions of principal component analysis (PCA). The first approach proposes the concept of y-indices through use of a transposed formulation of the data matrices utilized in traditional PCA. The y-indices are introduced to measure the differences between sensor reading

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

Improved sensor fault detection, isolation, and mitigation using multiple observers approach
Systems Science & Control Engineering, 2017 Traditional fault detection and isolation (FDI) methods analyze a residual signal to detect and isolate sensor faults. The residual signal is the difference between the sensor measurements and the estimated outputs of the system based on an observer. The

Design of Fault Detection Filters for Periodic Systems [PDF]
, 2004 We propose a numerically reliable computational approach to design fault detection filters for periodic systems. This approach is based on a new numerically stable algorithm to compute least order annihilators without explicitly building time-invariant ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...
