We hypothesized that our institutional standard practice for preanesthesia equipment checkout, based in part on US Food and Drug Administration recommendations, failed to detect a significant number of faults (absent or nonfunctional equipment). We designed a new, computer-based, highly interactive electronic checklist that emulated the checklist methods used in aviation and military settings a...

BERRY, R.F. & BANKS, M.R., 1985 (31 :vii): Striations on minor faults and the structure of the Parmeener Super-group near Hobart, Tasmania. Pap. Proc. R. Soc. Tasm. 119:23-29. ISSN 0080-4071. University of Tasmania, Hobart, Tasmania, Australia, 7000. Fault striations were measured on 104 minor faults within the Parmeener Super-group near Hobart. The fault striations probably reflect the complex...

In recent years, embedded memories are the fastest growing segment of system on chip. They therefore have a major impact on the overall Defect per Million (DPM). Further, the shrinking technologies and processes introduce new defects that cause previously unknown faults; such faults have to be understood and modeled in order to design appropriate test techniques that can reduce the DPM level. T...

Defect inspection is required for process control and to enhance chip yield. Electrical measurements at test structures are commonly used to detect faults. To improve the accuracy to evaluate the defects that have caused such faults, this paper presents a strategy to analyze single and multiple faults to precisely determine the number, layer and location of randomly distributed defects within a...

In this study an observer-based novel design of robust control system with an estimate scheme of sensor states to accommodate extended bounded-sensor faults is proposed. The sensor faults are, in general, modeled as polytopic bounds in robust control framework and are usually given as a priori assumption. But, in practice, the sensors that are subject to faults are especially vulnerable to vari...

Embedded content addressable memories (CAMs) are important components in many system chips. In this paper two efficient March-like test algorithms are proposed. In addition to typical RAM faults, they also cover CAMspecific comparison faults. The first algorithm requires 9N Read/Write operations and 2(N + W ) Compare operations to cover comparison and RAM faults (but does not fully cover the in...

We investigate the problem of reliable computation in the presence of faults that may arbitrarily corrupt memory locations. In this framework, we consider the problems of sorting and searching in optimal time while tolerating the largest possible number of memory faults. In particular, we design an O(n log n) time sorting algorithm that can optimally tolerate up to O( √ n log n ) memory faults....

This paper presents a recursive strategy for online detection of actuator faults on a unmanned aerial system (UAS) subjected to accidental actuator faults. The proposed detection algorithm aims to provide a UAS with the capability of identifying and determining characteristics of actuator faults, offering necessary flight information for the design of fault-tolerant mechanism to compensate for ...
