The sum of periodic functions with incommensurable periods is not a periodic function; for example, cosx+ cos (x√2) is not a periodic function. Functions of this kind, however, have many properties in common with periodic functions and are the simplest examples of so-called almost periodic...
The period for any periodic function ( functions that repeat themselves over a certain period) is the length of the cycle over which the function repeats itself. If you see a sine or a cosine wave graph, it repeats itself over a length of 2pi (360 degrees). So, the period for ...
it is found that the period effect is much greater than the cohort effect, indicating that changes in public attitudes toward authority, choices between free speech and economic stability, and attitudes toward private life are accompanied by periodic changes in the market reform, urbanization, and ...
Periodic formulation The aim of the scheduling is to minimize a cost function. The most commonly used cost function is the number of processors. However, it is also important to include other hardware resources that consume significant amounts of chip area and power. For example, memory is comp...
the semi-amplitude of the planet is detected to better than 5σsignificance. The FCO method clearly recovered the transit ephemeris, but to ensure that a false signal was not somehow introduced by the method, simulated data sets with periodic signals were analyzed, which confirmed FCO’s accuracy...

interpretation services is based on a three-pronged approach: (a) reliance on exacting standards in recruiting language staff only through periodic competitive language examinations in the relevant language professions; (b) provision of training and close and continuing supervision of junior language staff...

This paper addresses the multi-period inventory game of two substitutable products with learning, in which the demand distribution form in each period is known but one or more parameters are unknown in advance. The retailers update the estimates of the unknown parameters using the historical demand...
