This paper reviews the use of set-membership methods in fault diagnosis (FD) and fault tolerant control (FTC). Setmembership methods use a deterministic unknown-but-bounded description of noise and parametric uncertainty (interval models). These methods aims at checking the consistency between observed and predicted behaviour by using simple sets to approximate the exact set of possible behavio...

Fault diagnosis in the presence of noise and model errors is of fundamental importance. In the paper, the meaning of fault isolation performance is formalized by using the established notion of coverage and false coverage from the field of statistics. Then formal relations describing the relationship between fault isolation performance and the residual related design parameters are derived. For...

some applications are critical and must designed Fault Tolerant System. Usually Voting Algorithm is one of the principle elements of a Fault Tolerant System. Two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. Majority confronts with the problem of threshold limits and voter of weight...

This paper introduces different views for understanding problems and faults with the goal of defining a method for the formal specification of systems. The idea of Layered Fault Tolerant Specification (LFTS) is proposed to make the method extensible to fault tolerant systems. The principle is layering the specification in different levels, the first one for the normal behavior and the others fo...

In software testing, fault detection and removal process is one of the key elements for quality assurance of the software. In the last three decades, several software reliability growth models were developed for detection and correction of faults. These models were developed under strictly static assumptions. The main goal of this article is to investigate an optimal resource allocation plan fo...

The paper will introduce the basic idea of fault location method based on triangulation principle. At the beginning, the summary of weaknesses of known methods for fault location in medium voltage networks with tree topology will be presented. Then the basic principle of proposed method will be described, together with the analysis of critical factors influencing its usability. The last part of...

Fault-tolerance is the survival attribute of the real-time software system. The software should provide correct results in the face of various failures. A major technological concern for the coming years is the ever widening gap between the demand for high quality, robust software and its supply. Software fault tolerance is basically the design faults in the computer system. Its function is to ...

Abstract. The probabilistic fault displacement hazard analysis is one of the newest methods estimating amount in surface rupture areas. Considering strike-slip mechanism north Tabriz fault, Iran, using earthquake method and historical earthquakes 1721 1780, has been investigated, different scenarios estimated. fault's 50–60 km long section was selected as source possible from its data. Two were...

The principle, that the rate of internal viscous dissipation is at a minimum, is incorrect when temperature and velocity fields are linked through temperature-dependent viscosity or density. This makes it inappropriate for the study of spreading ridge – transform fault systems or other plate-tectonic problems with large density stratification resulting from large temperature gradients. Correcti...
