g-Good-Neighbor Conditional Diagnosability and g-Extra Conditional Diagnosability of Hypercubes Under Symmetric PMC Model [PDF]

Jisuanji kexue
Fault diagnosis plays a very important role in maintaining the reliability of multiprocessor systems,and the diagno-sability is an important measure of the diagnosis capability of the system.Except for the traditional diagnosability,there are also ...

Diagnosability of composite automata based on semi-tensor product

Systems Science & Control Engineering, 2021
Fault diagnosis is an important issue of partially observed discrete event systems (DESs). In this problem, fault detection and isolation are two associated tasks, where a fault is diagnosable if it can be detected certainly with a finite delay ...

Fault Isolability Analysis and Optimal Sensor Placement for Fault Diagnosis in Smart Buildings

Energies, 2019
Faults and anomalies in buildings are among the main causes of building energy waste and occupant discomfort. An effective automatic fault detection and diagnosis (FDD) process in buildings can therefore save a significant amount of energy and improve ...

A Unified Diagnosability Evaluation Framework for Complex Systems

Chemical Engineering Transactions, 2013
A unified diagnosability evaluation framework for complex systems is presented. In this framework, four elements are used to define the diagnosability evaluation problem: fault space, indication space, fault-indication relation, and metrics. In different

Deep PCA-Based Incipient Fault Diagnosis and Diagnosability Analysis of High-Speed Railway Traction System via FNR Enhancement

Machines, 2023
In recent years, the data-driven based FDD (Fault Detection and Diagnosis) of high-speed train electric traction systems has made rapid progress, as the safe operation of traction system is closely related to the reliability and stability of high-speed ...

Diagnosability of Vector Discrete-Event Systems Using Predicates

IEEE Access, 2019
The diagnosability problem of faults is studied in the framework of vector discrete-event system (VDES). A VDES is a discrete-event system model in which a system state is represented by a vector with integer components, and state transitions are ...

Fault Diagnosis in Partially Observed Petri Nets Using Redundancies

IEEE Access, 2018
This paper is devoted to the development of an approach to the diagnosability of a system described in the framework of partially observed Petri nets (POPNs) such that the developed fault diagnosis technique can be widely applicable to systems with ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

On–The–Fly Diagnosability Analysis of Bounded and Unbounded Labeled Petri Nets Using Verifier Nets

International Journal of Applied Mathematics and Computer Science, 2018
This paper considers the problem of diagnosability analysis of discrete event systems modeled by labeled Petri nets (LPNs). We assume that the LPN can be bounded or unbounded with no deadlock after firing any fault transition.
