Availability of a Redundant System
IEEE Transactions on Reliability, 1978The Laplace transform of the availability of a multicomponent system with spares, is obtained by the regeneration point technique.

Redundant consecutive-k systems
Operations Research Letters, 1987We introduce redundancy into the consecutive-k (-out-of-n) systems which have recently been widely studied. We study three problems: (i) compute the reliabilities for such systems, (ii) assign components with various working probabilities to a given system to maximize its reliability, (iii) select a system under hardware constraints to maximize the ...

Intermittently used redundant system
Microelectronics Reliability, 1978Abstract This paper discusses the stochastic behaviour of a 2-unit cold-standby intermittently used system and derives the Laplace-Stieltjes Transform of 1. (i) the distribution of first disappointment time; 2. (ii) probability that the system is under disappointment at time t ; 3.

Abstract A robot is said to be ‘redundant’ when it has a superabundance of actuated joints with respect to the task it is required to perform. In Chapter 7, we described methods for finding the finite number of distinct assembly-configurations that are available in a six-actuator serial arm when the location of its end-effector body is ...

Redundancy and Trichotomous Systems
Journal of the Society for Industrial and Applied Mathematics, 1964The problem of obtaining maximum reliability by increasing redundancy for multi-component systems in which the components are capable of three possible states of behavior is considered. Special attention is given to “k out of n” systems and an expression is derived which gives the value of k for maximum system reliability given n and the state ...

Discussion: Excitation system redundancy
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008Today, technology continues to evolve as more functionality is placed into smaller packages with the aid of new innovative hardware and improving software in digital excitation systems. The advancement of the microprocessor has provided the means to increase the feature function capacity into less hardware and provide additional means to enhance ...

Hot redundant versus cold redundant systems
Reliability Engineering, 1981Abstract Unforeseen breakdowns of spaceborne systems and ground-based systems, caused by chance failure of parts, are minimized by incorporating redundant units in them. The redundancy can be active or stand-by. In this paper both types of redundant systems have been discussed and analysed.

Redundancies in Cyclic Systems
Zeitschrift für Elektrochemie, Berichte der Bunsengesellschaft für physikalische Chemie, 1960AbstractA general method of finding explicit expressions for the ringproduced redundancies in a cyclic molecule is given, with detailed application to the planar six‐membered ring (C6H6, C4H4N2) and the fourmembered non‐planar ring of C2v symmetry.
