Second order nonlinear interactions in periodic waveguides
Proceedings of 2004 6th International Conference on Transparent Optical Networks (IEEE Cat. No.04EX804), 2005We illustrate the results of an investigation of second harmonic generation (SHG) in planar nonlinear waveguides assisted by a Bragg grating, along the propagation direction, reproducing a photonic-bandgap (PBG) structure. The analysis is performed in the time domain using a home-made finite difference time domain (FDTD) computer code that exploits the

This chapter discusses the nonlinear first order differential equation $$\left\{ {\begin{array}{*{20}{c}} {y' = f\left( {t,y} \right){\text{ a}}{\text{.e}}{\text{. on }}\left[ {0,T} \right]} \\ {y\left( 0 \right) = y\left( T \right)} \end{array}} \right.$$ (1.1) where f: [0,T] × R → R is a L 1-Caratheodory function (see definition 3.2).

Confirmation Theory, Order, and Periodicity
Philosophy of Science, 1963This 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.

Periodic Boundary Layers of Second‐order Fluids
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1966AbstractThis paper is devoted to a study of boundary layer flow of certain second‐order fluids around a periodically oscillating cylinder. The velocity field is obtained by a process of successive approximations. In the region near the wall the stream lines of the secondary flow are closed loops while away from the wall they are U‐shaped.

Periodic Extensions of Ordered Groups
1989A PARTIAL ORDER P on a group G is a subset P of G satisfying the following conditions: (i) PP = 1 (ii) P ∩ P -1 = 1 and (iii) Pg = gP for all g in G.

Auctions in the post-change-order period
2015Summary: 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.
