Monitoring the quality of service in a multi-domain network allows providers to ensure the control of multi-domain service performance. A multi-domain service is a service that crosses multiple domains. In this paper, we propose several mechanisms for fault detection and fault localization. A fault is detected when an end-to-end contract is not respected. Faulty domains are domains that do not ...

One of the common misconceptions about stuck-at fault model is that it does not model a physical defect accurately and therefore is not adequate for testing defects in the advancing technologies. Stuck-at fault model can be described as anything but a physical defect model. You can call it Abstract, Logical, Boolean, Symbolic, Functional, or Behavioral model, but don’t call it a physical defect...

Fault-tolerance analysis reveals possible system behavior under the influence of faults. Such analysis is essential for satellites where faults might be caused by space radiation and autonomous recovery is needed. In this paper we present a statistical simulation approach for fault-tolerance analysis of satellite On-Board Computers (OBCs) that are based on Commercial Off-The-Shelf (COTS) compon...

An important problem in fault diagnosis is how to locate faulty components by analysing performance measurements from those components. In this paper, we present an algorithm that uses the informationtheoretic Minimum Message Length (MML) principle to locate faults in tree-structured networks. Treestructured networks are an important application for fault diagnosis due to their use as distribut...

Fault diagnosis of analog circuits is essential for guaranteeing the reliability and maintainability of electronic systems. A novel analog circuit fault diagnosis approach based on greedy kernel principal component analysis (KPCA) and one-against-rest support vector machine (OARSVM) is proposed in this paper. In order to obtain a successful fault classifier, eliminating noise and extracting fau...

Forest fires are amongst the significant causes threatening our environment degradation nowadays. Current fire detection systems lack the capability of fire triggering detection from its early stages. Wireless sensor networks (WSN) as a solution letting to gather sensory data measurements, such as humidity and temperature, from all points of forest continuously, and, provide reliable and depend...

The paper is engaged with the framework of designing adaptive fault estimation for linear continuous-time systems with distributed time delay. The Lyapunov-Krasovskii functional principle is enforced by imposing the integral partitioning method and a new equivalent delaydependent design condition for observer-based assessment of faults are established in terms of linear matrix inequalities. Asy...

1 Introduction The secret keys manipulated by cryptographic circuits can be extracted using fault injections associated with differential cryptanalysis techniques [1]. Such faults can be induced by different means such as lasers, voltage glitches, electromagnetic perturbations or clock skews. Several countermeasures have been proposed such as random delay insertions, circuit duplications or err...

Partial discharge is the commencement of failure of insulation of electrical devices used at high voltage. If such discharge is not detected then fault may increase at the working duration. Basically partial discharge is the cause of failure of insulation in electrical equipment. The insulation of electrical equipment deteriorates due to thermal, mechanical, electrical and environmental stresse...

A generalized principle of PD faults observer design for continuous-time linear MIMO systems is presented in the paper. The problem addressed is formulated as a descriptor system approach to PD fault observers design, implying the asymptotic convergence both the state observer error as fault estimate error. Presented in the sense of the second Lyapunov method, an associated structure of linear ...
