ACTIVE REDUNDANCY ALLOCATIONS IN SERIES SYSTEMS
Probability in the Engineering and Informational Sciences, 2011We consider the problem of optimally allocating one/two active spares in series systems. Lifetimes of different configurations are compared with respect to the reversed failure rate order, the failure rate order, the increasing concave order, and the stochastic precedence order.

Series Systems and Reliability Demonstration Tests
Operations Research, 1984For series systems at equilibrium, the exponential distribution for times between failures is reasonably well justified. In the transient state, the exponential distribution applies also, but with a time varying scale parameter. Ignoring this parameter and using a partly aged system to make inferences about the mean life of a fully aged system can ...

Availability of a Special Series System
IEEE Transactions on Reliability, 1981The purpose of the paper is two fold; i) To obtain the availability of a 2-unit series system with a special shutting-off property, and with all the repair distributions general. ii) To extend the result for a n-unit system with general repair distributions which has practical applications in radial distribution systems of power supply.

In section 2.1, page 34, a simple example is used to illustrate the need for estimating the reliâbility of series systems. On page 34 a structural system with two potential failure modes defined by the safety margins M1 = f1(X1, X2) and M2 = f2 (X1, X2) is considered. If Fi = {Mi ≤ 0}, i = 1, 2 the probability of failure Pf of the structural system is

Modeling Nonlinear Systems by Volterra Series
Journal of Engineering Mechanics, 2010The Volterra-series expansion is widely employed to represent the input-output relationship of nonlinear dynamical systems. This representation is based on the Volterra frequency-response functions (VFRFs), which can either be estimated from observed data or through a nonlinear governing equation, when the Volterra series is used to approximate an ...

IEEE Transactions on Reliability, 1977
This paper investigates the pdf of time to system failure of a series-parallel system subject to failures and repairs and derives expressions for pdf's of times to system failure in terms of their Laplace Transform.

Time series modeling of neuromuscular system
Biological Cybernetics, 1984The dynamic response of the human ankle joint to a bandlimited random torque perturbation superimposed on a constant bias torque is observed in normal human subjects. The applied torque input, the joint angular rotation output, and the electromyographic activity using surface electrodes from the extensor and the flexor muscles of the ankle joint were ...

Stochastic functional fourier series, Volterra series, and nonlinear systems analysis
IEEE Transactions on Automatic Control, 1979A functional Fourier series is developed with emphasis on applications to the nonlinear systems analysis. In analogy to Fourier coefficients, Fourier kernels are introduced and can be determined through a cross correlation between the output and the orthogonal basis function of the stochastic input. This applies for the class of strict-sense stationary

Solving STIFF systems by Taylor series
Applied Mathematics and Computation, 1989A new insight into the numerical solution of stiff systems of ODE's is brought by application of long Taylor series (up to 30 terms). Most of stiff problems are of the type where there is a linear ODE hidden within the stiff system of ODE's. When the hidden linear ODE is of order one, there is an exponential component in the solution.

Series-series resonant IPT system analysis under frequency mismatch
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015Inductive Power Transfer (IPT) is a promising solution for charging the electric vehicles (EVs). The first IPT systems (IPTSs) were needing a strong coupling between transmitter and receiver coils to achieve a satisfactory efficiency in the power transfer.
