Hybrid Z-Source Circuit Breaker with Thomson Coil for MVDC

Energies, 2023
Hybrid circuit breakers are the most promising circuit breakers among DC circuit breakers. Conventional hybrid circuit breakers complete fault current isolation by converting current to IGBT when fault current occurs.

Fault isolability with different forms of the faults–symptoms relation [PDF]

International Journal of Applied Mathematics and Computer Science, 2016
AbstractThe definitions and conditions for fault isolability of single faults for various forms of the diagnostic relation are reviewed. Fault isolability and unisolability on the basis of a binary diagnostic matrix are analyzed. Definitions for conditional and unconditional isolability and unisolability on the basis of a fault information system (FIS),

Double Fault Detection of Cone-Shaped Redundant IMUs Using Wavelet Transformation and EPSA

Sensors, 2014
A model-free hybrid fault diagnosis technique is proposed to improve the performance of single and double fault detection and isolation. This is a model-free hybrid method which combines the extended parity space approach (EPSA) with a multi-resolution ...

Fault detection and isolation on a noisy nonlinear circuit [PDF]

, 2012
In this paper fault detection and isolation (FDI) schemes are applied in the context of the surveillance of emerging faults in an electrical circuit. The FDI problem is studied on a noisy nonlinear circuit, where both abrupt and incipient faults in the ...

Fault isolation in multicast trees [PDF]

Proceedings of the conference on Applications, Technologies, Architectures, and Protocols for Computer Communication, 2000
Fault isolation has received little attention in the Internet research literature. We take a step towards addressing this deficiency, exploring robust and scalable techniques by which multicast receivers can (in some cases, approximately) locate the on-tree router responsible for a route change, or the link responsible for significant ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Fault Diagnosis for Space-Borne Fiber-Optic Gyroscopes Using a Hybrid Method

IEEE Access, 2020
Timely detection and isolation of the failures in attitude sensor is a critical task to ensure the normal operation of the satellite. This article proposes a fault detection and isolation scheme for the four-axis fiber-optic gyroscopes using a hybrid ...

Polynomial-time T-depth Optimization of Clifford+T circuits via Matroid Partitioning [PDF]

, 2013
Most work in quantum circuit optimization has been performed in isolation from the results of quantum fault-tolerance. Here we present a polynomial-time algorithm for optimizing quantum circuits that takes the actual implementation of fault-tolerant ...
