The present invention is in the field of manufacturing, processing and design, and also packaging. Nesting is the process of placing objects together with minimal spaces between them. The invention is described below in two forms. The first form, set forth in Part I below, is directed to methods and systems for nesting of two dimensional (D) objects in a target plane. The second form, set forth in Part II below, is directed to methods and systems for nesting three dimensional (D) objects in a target volume. The specific details of the preferred embodiments are set forth in those respective parts.

Method and systems for nesting objects

A system for reducing the formation of NO.sub.x pollutants during the combustion of liquid fuel in a gas turbine engine. The system comprises introducing an externally modulated, rapidly-pulsed, oscillated or sinusoidal fuel flow delivery rate (generically referred to as 'modulated') to produce a controlled degree of combustor air input flow oscillation and bulk flow oscillation within the combustor which enhances the fuel-air mixing rate and homogeneity within the combustor, decreases the residence time of transition fuel/air mixtures prone to NO.sub.x formation, and substantially decreases the NO.sub.x concentration in the resulting combustion gas product without creating a net pressure gain throughout the combustion chamber.
