Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...

Abstract - Use of efficient signal processing tools (SPTs) to extract proper indices for fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The Part1 of the two parts paper focuses on Fourier-based techniques including fast Fourier transform and short time Fourier transform. In this paper, all utilized SPTs which have been employed for fault fete...

Both intermittent and persistent faults may occur in a wide range of systems. We present in this paper the introduction of intermittent fault handling techniques into ProDiagnose, an algorithm that previously only handled persistent faults. We discuss novel algorithmic techniques as well as how our static Bayesian networks help diagnose, in an integrated manner, a range of intermittent and pers...

An experimental system for computing robust tests for stuck-open faults in static CMOS circuits is presented. It constructs robust test-pairs from tests for stuck-at faults by identifying several classes of FETs. Robust tests for stuck-open faults in FETs belonging to these classes are constructed from any stuck-at test set by carefully constructing initialization vectors. Initialization vector...

Fieldand petrographic studies of the Paleozoic metamorphic rocks of New York City suggest a new interpretation of the stratigraphy and structure of the region and has delineated a number of ductileand brittle faults. The belt of rocks originally lumped together as the Manhattan Schist is now interpreted to consist of three mappable units structurally imbricated by two major ductile faults, the ...

Any input vector that does not detect a fault is called an antitest for that fault Given two faults an in put vector that detects exactly one of those faults is an exclusive test A concurrent test for two faults must detect both faults The problems of gener ating these three types of tests involve detection of multiple faults We transform each of these problems into a single fault ATPG problem ...

August 1998 The distribution of faults within any particular software product is not uniform. For example, 47 percent of the faults found by users of OS/370 were associated with only 4 percent of the modules [1]. Therefore, what is needed are metrics that can be applied to detailed designs to predict which modules will be faultprone. Then, instead of wasting money detecting and correcting fault...

Current memory testing methods rely on fault models that are inadequate to accurately represent potential defects that occur in modern, often specialized, memories. To remedy this, the authors present a formal framework for modeling and testing special-purpose memories. Their approach uses three models: the transistor circuit, the event-sequence model, and finite-state machines. The methodology...

for testing linked faults. We prove that new algorithms have higher fault coverage than existing march tests for linked multiple faults. Many fault models for RAMs and tests for faults of these models are available. In most cases these tests allow for the detection of single faults only. This paper contains fault coverage analysis of march tests which detect multiple faults. It is shown there a...

Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...
