Pumps play a central role in water supply systems, especially for high-rise buildings. The inefficiency or failure of pumps leads to high energy cost or water supply disruption. Thus, it is crucial to monitor their health. While advanced pumps have in-...

This paper considers technical systems described by nonlinear dynamic models. The fault tolerance property of such systems is ensured by introducing feedback with full or partial fault decoupling. The solution is based on separating a subsystem ...

Rapid progress in CMOS technology since the late 1990s has increased the vulnerability of processors toward faults. Subsequently, the focus of computer architects has shifted toward designing fault-tolerance methods for processor architectures. ...

This paper proposes a method for diagnosing linear dynamic systems described by discrete-time models with exogenous disturbances based on interval observers. Formulas are derived to construct an interval observer producing two values of the ...

This paper considers the problem of identifying (estimating) faults in systems described by linear models under exogenous disturbances. It is solved using optimal control methods; in comparison with sliding mode observers, they avoid high-...

In this tutorial, we provide an extensive survey of the work on dispersion of mobile robots, introduced by Augustine and Moses Jr. [ICDCN 2018]. The problem of dispersion of k robots, initially arbitrarily placed on the nodes of an n node graph, ...

With the improvement of innovation, software developers consistently build up a new version of software by adding new features in the previously existing version of the software. In resent day's competitive market, the reliability and release time ...

A nonhomogeneous Poisson process‐based software reliability growth model (SGRM) has been developed incorporating change point, imperfect debugging, and fault dependency for multi‐release software. Parameters of the proposed SRGM are estimated using ...

Grammar-based fuzzers are effective and efficient. They can produce an infinite number of syntactically valid test inputs, which can be used to explore the input space without bias. However, it is notoriously difficult to generate focused inputs to ...

Grammar-based test generators are highly efficient in producing syntactically valid test inputs and give their users precise control over which test inputs should be generated. Adapting a grammar or a test generator towards a particular testing goal can ...

Performance and power constraints come together with Complementary Metal Oxide Semiconductor technology scaling in future Exascale systems. Technology scaling makes each individual transistor more prone to faults and, due to the exponential increase in ...

Deep Neural Networks (DNNs) - the state-of-the-art computational models for many Artificial Intelligence (AI) applications - are inherently compute and resource-intensive and, hence, cannot exploit traditional redundancy-based fault mitigation ...

Human factors play a significant role in software development. When the human element is not considered in software development, it may lead to faulty software which may cause delays in software delivery. Faults in software are mostly because of human ...

Riding on the success of SDN for enterprise and data center networks, recently researchers have shown much interest in applying SDN for critical infrastructures. A key concern, however, is the vulnerability of the SDN controller as a single point of ...

Recently, there has been significant increase in interest on Smart Grid security. Researchers have proposed various techniques to detect cyber-attacks using sensor data. However, there has been little work to distinguish a cyber-attack from a power ...

In a unit testing environment, understanding the relationship between production classes and test classes has implications for overall maintenance and hence systems development costs. Equally, the fault-proneness of each type may have a similar ...

In the domain of information systems modeling for dependability is an established method. Most approaches dealing with structural or probabilistic modeling do not consider time information and handle only discrete data. But in reality systems have a ...

In current scenario, On-Chip Network advances to fulfill higher bandwidth demand rises by chip multiprocessor (CMP). Each nanometer technology of transistor is giving high performance but becoming more fault prone. Hardware faults are injected inside ...

At ICSE'2013, there was the first session ever dedicated to automatic program repair. In this session, Kim et al. presented PAR, a novel template-based approach for fixing Java bugs. We strongly disagree with key points of this paper. Our critical ...

What are the types of mistakes ("faults'") that novice GOAL programmers make, and how do they manifest as failures? This question is important since it has significant implications to the ongoing design of GOAL, and other agent-oriented programming ...

A fundamental aspect of a system's performance over time is the number of faults it generates. The relationship between the software engineering concept of "coupling" (i.e., the degree of inter-connectedness of a system's components) and faults is still ...
