Composite design patterns

Formalizing Design Patterns: A Comprehensive Contract for Composite

Software patterns are used almost universally across design communities as the preferred mechanism for communicating best practice. And while the design archetypes captured by patterns continue to exert significant influence on software design decisions, there is no rigorous foundation for ensuring implementation correctness or reasoning about the systems in which patterns are applied. In this ...

Optimum composite material design

— The microstructure identification problem is treated : given certain phases in given volume fractions, how to mix them in aperiodic cell so that the effective material constants of the periodic composite lie the closest possible to certain prescribed values ? The problem is studied for the linear conduction équation. It is stated in terms of optimal con trol theory ; the admissible micro geom...

Design of a composite right / left-handed slab-type material com- posed of multilayer metallic patterns

In this paper, a composite right/left-handed (CRLH) slab-type material excited by plane wave is proposed. It is composed of multilayer metallic patterns between dielectric substrates. The equivalent circuit is shown to design a balanced CRLH material. The balanced CRLH characteristics are measured. Next the CRLH material composed of four kinds of cells with different dispersion relation is desi...

Cellulose composite structures – by design

Elementary and Composite Defects of Striped Patterns

Labyrinthic patterns are observed both in systems where the uniform states are metastable, as a result of a front instability, and in systems displaying a cellular instability, when the band of excited Fourier modes is wide enough to support resonant interactions between modes lying on different shells. We show that the phase formalism is a suitable description for low-density labyrinthic patte...
