Research on Four-Quadrant Input Over-current Fault Diagnosis of Electric Locomotive Based on Recursive 2-Classification Method

机车电传动, 2019
Four-quadrant over-current fault is one of the main faults of the HXD1 locomotive traction converter. Due to the class distribution of fault cause is unbalanced and there are a lot of over-current fault causes, four-quadromt over-current fault is ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

SEU fault classification by fault injection for an FPGA in the space instrument SOPHI [PDF]

2017 NASA/ESA Conference on Adaptive Hardware and Systems (AHS), 2017
Fault injection through partial dynamic reconfiguration can simulate upsets in configuration memory of SRAM-based FPGAs. FT-UNSHADES 2 is an automated set-up, which runs multiple fault injection campaigns in batch mode, while automatically applying stimuli and comparing output vectors.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

The walls boundary fault zone and the MØre TrØndelag fault complex:: a case study of two reactivated fault zones. [PDF]

, 2001
It is commonly observed that ancient faults or shear zones can become reactivated again and again, either within the same or even superimposed tectonic episodes, yet millions of years apart.

A Study of Motor Bearing Fault Diagnosis using Modulation Signal Bispectrum Analysis of Motor Current Signals

, 2013
Failure of induction motors are a large concern due to its influence over industrial production. Motor current signature analysis (MCSA) is common practice in industry to find motor faults. This paper presents a new approach to detection and diagnosis of

Phase-compensation-based dynamic time warping for fault diagnosis using the motor current signal [PDF]

, 2012
Dynamic time warping (DTW) is a time-domain-based method and widely used in various similar recognition and data mining applications. This paper presents a phase-compensation-based DTW to process the motor current signals for detecting and quantifying ...

An Integrated Fault Detection, Classification, and Region Identification Methodology Applied to Onshore Wind Farm Collector Systems

IEEE Access
This paper is motivated by the growing penetration of renewable power plants in electrical systems worldwide and the scarcity of studies evaluating fault detection, classification, and localization tasks when applied within wind farms, i.e., their ...
