A Novel Sub-Module-Based Line-Commutated Converter That Is Actively Resistant to Commutation Failure

open access: yesActuators
To improve the ability of line-commutated converters (LCCs) to resist commutation failure (CF) when a fault occurs on the AC side, a novel sub-module-based LCC topology actively resistant to CF is proposed in this paper.

On the representation of sensor faults in fault detection filters [PDF]

open access: yesProceedings of 32nd IEEE Conference on Decision and Control, 1994
Presents an extension of the well known Beard-Jones detection filter that permits the isolation of sensor faults in a dynamic system to a fixed direction. The method is based on augmenting the system equations by an auxiliary state to represent the dynamic behavior of the sensor fault, and in effect converts the sensor fault into the same form as an ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Enhanced pilot protection scheme for half-wavelength transmission line based on the conservation of traveling wave energy

open access: yesInternational Journal of Electrical Power & Energy Systems
The half-wavelength transmission system is a viable technology for long-distance and large-capacity power transmission. It can safely and efficiently transmit a large amount of clean energy to remote load centers.

Review on Frequency Security Assessment and Coordinated Inertia Control for Low-Inertia Modern Power Systems [PDF]

open access: yesDianli jianshe
[Objective] The large-scale integration of high-penetration renewable energy sources(RES)and power-electronic-interfaced devices has continuously displaced the conventional synchronous generators(SG). This transition has led to a significant reduction in

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Prediction and Fault Detection of Environmental Signals with Uncharacterised Faults

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
Many signals of interest are corrupted by faults of anunknown type. We propose an approach that uses Gaus-sian processes and a general “fault bucket” to capturea priori uncharacterised faults, along with an approxi-mate method for marginalising the potential faultinessof all observations.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

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.

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
