Experimentally Validated Neural Networks for Sensors Redundancy Purposes in Spark Ignition Engines
SAE International Journal of Engines, 2023<div>In the aeronautical field, aircraft reliability is strictly dependent on propulsion systems. Indeed, a reliable propulsion system ensures the safety of pilots and passengers and the possibility of making comfortable flights.

Analytical Redundancy Technology for Engine Reliability Improvement
SAE Technical Paper Series, 1986<div class="htmlview paragraph">The ARTERI concept for achieving engine control system fault detection, isolation, and accommodation is described. It uses analytical redundancy to improve system reliability in conjunction with or instead of hardware redundancy and can also be used as a diagnostic tool.

Reliability Analysis of a Dual-Redundant Engine Controller
SAE Technical Paper Series, 1981<div class="htmlview paragraph">A Markov model is developed to predict the reliability of a full-authority, dual-redundant aircraft engine controller. The effects of failures of any of the controller’s sensors, electronic interface modules, processors and actuators, as well as the consequences of redundancy management decisions are modeled.

Redundancy handling with model-based systems engineering
2016Redundancy is widely used in safety-critical systems to improve their reliability. This paperproposes a framework to model different kinds of redundancy in model-based systems engineering process.A SysML extension which allows integrating redundancy-relevant properties in the system model in orderto better represent system architecture is introduced ...

A comparison of redundant CORDIC rotation engines
[1991 Proceedings] IEEE International Conference on Computer Design: VLSI in Computers and Processors, 2002The CMOS implementation of two high performance rotation processors using redundant CORDIC are reviewed and compared. One of the designs uses a variable scaling factor while the other is with constant scaling. The latter also incorporates some radix-4 CORDIC stages. Characteristics for 1.2 mu m CMOS implementations are given. >

Intelligent redundant systems for small turbo-compressor engines
2014 IEEE International Symposium on Intelligent Control (ISIC), 2014Increased redundancy of systems has always been one of the key points to increase reliability and safety of operation of aircraft engines. A special class of such engines is represented by small turbo-compressor engines suitable for propulsion of small aircraft or ground and laboratory use.

Necessary Redundancy in Geotechnical Engineering
Journal of Geotechnical Engineering, 1989The causes of geotechnical engineering failures are listed and discussed. Many of these could have been prevented or damages mitigated if redundancy had been used in design and construction. Redundancy is defined in special terms applicable to geotechnical engineering.

Identifying redundant search engines in a very large scale metasearch engine context
Proceedings of the 8th annual ACM international workshop on Web information and data management, 2006For a given set of search engines, a search engine is redundant if its searchable contents can be found from other search engines in this set. In this paper, we propose a method to identify redundant search engines in a very large-scale metasearch engine context. The general problem is equivalent to an NP hard problem -- the set-covering problem.

Avoiding Redundant Testing in Application Engineering
2010Many software product line testing techniques have been presented in the literature. The majority of those techniques address how to define reusable test assets (such as test models or test scenarios) in domain engineering and how to exploit those assets during application engineering. In addition to test case reuse however, the execution of test cases
