Almost-Periodic Higher Order Statistic Estimation

IEEE Transactions on Information Theory, 2011
In this paper, stochastic processes with higher order statistical functions decomposable into an almost-periodic function plus a residual term not containing finite-strength additive sinewave components are considered. These processes arise in mobile communications when almost-cyclostationary (ACS) processes pass through time-varying channels.

DETECTION OF PERIODICITIES BY HIGHER‐ORDER CROSSINGS

Journal of Time Series Analysis, 1987
Abstract. The axis‐crossing counts in a time series and in its successive differences are called higher‐order crossings (HOC). Under the Gaussian assumption the sequence of expected HOC is monotone increasing and admits a spectral representation which establishes a clear connection between HOC and the spectrum.

Auctions in the post-change-order period

2015
Summary: A change order is frequently initiated by either the supplier or the buyer, especially when the contract is long-term or when the contractual design is complex. In response to a change order, the buyer can enter a bargaining process to negotiate a new price. If the bargaining fails, she pays a cancellation fee (or penalty) and opens an auction.

A tradeoff between period and order of linear periodic stabilizing compensators

Automatica, 1996
The problem of stabilizing a discrete-time linear time-invariant plant by a linear periodic compensator is considered. It is shown that it is possible to trade off compensator order for an increased period. Also, it is shown that first-order linear periodic controllers can be used to solve the strong and simultaneous stabilization problems.

Confirmation Theory, Order, and Periodicity

Philosophy of Science, 1963
This paper examines problems of order and periodicity which arise when the attempt is made to define a confirmation function for a language containing elementary number theory as applied to a universe in which the individuals are considered to be arranged in some fixed order.

The return period of order statistics

Annals of the Institute of Statistical Mathematics, 1961
It may be stressed that the results reached here are independent of the initial distribution and valid for any sample sizen and all order statistics. For example the expected return period for the smaller of two observations is 2, but infinite for the larger one and the variance of the return periods for both observations is infinite.

On the Long-Period Ordered Alloys

1974
Studies of the long-period ordered alloys are surveyed. Alloys that are in most cases f.c.c. in a disordered state often transform into that ordered state composed of regular antiphase domains which is represented by CuAuII but realized in many A3B type alloys such as Ag3Mg, Cu3 Pt II, Pd3Mn, Au3Cd, Au3Zn(H), Au3+Zn, Au3Mn, Cu3Pd(α″) etc.
