Software product lines are the common trend in software development which helps in reducing the development cost. Mostly the interaction faults are very difficult to identify during the process of debugging. By the use of combinatorial testing a set of features can be identified and all small combinations can be verified to a certain level only. By introducing random testing can improve the acc...

In dynamic systems that adapt to users’ needs and changing environments, dependability needs cannot be avoided. This paper proposes an orthogonal fault tolerance model as a means to manage and reason about multiple fault tolerance mechanisms that co-exist in dynamically adaptive systems. One of the key challenges associated with dynamically evolving fault tolerance needs is the feature interact...

This paper presents a fault model for interoperability testing of communication protocols that are modeled by communicating finite state machines, and proposes a technique that extends an initial interoperability test suite, which is given by another existing method, to be a test suite that can detect "almost all" interaction faults based on the fault model. We start with an interoperability te...

In this paper we deal with structured software fault-tolerance. Structured software fault tolerance are those techniques where redundancy (both for detection and correction) is applied to the individual blocks of software with the goal of masking or reveal errors internal to the block. Each technique has its own way of structuring the interactions among redundant parts and of managing the compl...

This paper studies the problem of fault detection and isolation (FDI) for multi-agent systems (MAS) via complex Laplacian subject to actuator faults. A planar formation of point agents in the plane using simple and linear interaction rules related to complex Laplacian is achieved. The communication network is a directed, and yet connected graph with a fixed topology. The loss of symmetry in the...

In recent years it has been recognized that the level of shear and normal stress along a fault can vary; thus the stress is spatially and temporally inhomogeneous. Moreover, it has also been suspected that faults might interact in some way, with the result that a variety of earthquake magnitudes might be produced along a given length of fault at varying times. In order to explore these ideas we...

For failure prediction and information interaction problems of multi-equipment health management, fault prediction technology of multi-equipment and multi-parameter was proposed based on the system network. The state judgment and fault diagnosis algorithm is adopted by SOM self-organizing feature map neural network, the network parameters and node structure are changed adaptively, and the real-...

Field evidence from recent earthquakes has shown that structures can be designed to survive major surface dislocations. This paper: (i) Describes three different finite element (FE) methods of analysis, that were developed to simulate dip slip fault rupture propagation through soil and its interaction with foundation–structure systems; (ii) Validates the developed FE methodologies against centr...
