Filter-Based Fault Detection and Isolation in Distributed Parameter Systems Modeled by Parabolic Partial Differential Equations

open access: yesIEEE Access, 2023
This paper covers model-based fault detection and isolation for linear and nonlinear distributed parameter systems (DPS). The first part mainly deals with actuator, sensor and state fault detection and isolation for a class of DPS represented by a set of

Automatic fault detection on BIPV systems without solar irradiation data [PDF]

open access: yes, 2014
BIPV systems are small PV generation units spread out over the territory, and whose characteristics are very diverse. This makes difficult a cost-effective procedure for monitoring, fault detection, performance analyses, operation and maintenance.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Backup protection method for half-wavelength transmission lines based on inverse-time characteristic

open access: yesInternational Journal of Electrical Power & Energy Systems
The advantages of ultra-high voltage (UHV) Half-wavelength AC transmission (HWACT) technology are achieving full-line reactive power self-balancing without the need for reactive power compensation equipment along the line and avoiding the Ferranti effect.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Adaptive reclosing scheme for flexible HVDC grid with single-pole ground fault based on residual voltage zero-crossing detection

open access: yesInternational Journal of Electrical Power & Energy Systems
To avoid the issue of blind reclosing in conventional flexible high voltage direct current (HVDC) grid, investigating an adaptive reclosing scheme capable of identifying fault nature and duration is essential.

Causality and Temporal Dependencies in the Design of Fault Management Systems [PDF]

open access: yes, 2017
Reasoning about causes and effects naturally arises in the engineering of safety-critical systems. A classical example is Fault Tree Analysis, a deductive technique used for system safety assessment, whereby an undesired state is reduced to the set of ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Inverse time overcurrent protection for low-frequency wind farm transmission lines based on transient current components

open access: yesInternational Journal of Electrical Power & Energy Systems
Low-Frequency Transmission Systems (LFTS) integrate the benefits of both high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) transmission technologies. This combination makes LFTS a significant innovation for transmitting large

Testing based on the RELAY model of error detection [PDF]

open access: yes, 1987
RELAY, a model for error detection, defines revealing conditions that guarantee that a fault originates an error during execution and that the error transfers through computations and data flow until it is revealed. This model of error detection provides
