An adaptive reclosing scheme for flexible DC grid based on residual voltage S-transformation

open access: yesScientific Reports
When a fault occurs on a line, it is necessary to quickly isolate the fault to improve the safety and reliability of the transmission system. Due to the lack of effective ability to identify the nature of faults, the traditional automatic reclosing ...

Pilot protection based on the quasi-directional element of LCL-tuned half-wavelength transmission line

open access: yesInternational Journal of Electrical Power & Energy Systems
To create HWTL characteristics, the electrical distance of AC transmission lines is compensated to half the power frequency wavelength by utilizing tuned circuits.

Clinical Course and Impact of Breaks in Therapy for Children With Relapsed/Refractory Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pediatric relapsed or refractory (R/R) solid tumors carry a dismal prognosis, and postrelapse patient experiences are not well described. We present postrelapse outcomes, including number of R/R events and subsequent therapy regimens.

Two‐Step Clustering‐Based Equivalent Modeling of Large‐Scale Wind Farms for Enhanced Primary Frequency Regulation

open access: yesWind Energy
The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations.

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.

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 ...

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

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

Case study: Bio-inspired self-adaptive strategy for spike-based PID controller [PDF]

open access: yes, 2015
A key requirement for modern large scale neuromorphic systems is the ability to detect and diagnose faults and to explore self-correction strategies. In particular, to perform this under area-constraints which meet scalability requirements of large ...

Immunotronics - novel finite-state-machine architectures with built-in self-test using self-nonself differentiation [PDF]

open access: yes, 2002
A novel approach to hardware fault tolerance is demonstrated that takes inspiration from the human immune system as a method of fault detection. The human immune system is a remarkable system of interacting cells and organs that protect the body from ...
