Abstract This chapter explores the structure, as opposed to just the existence, of the family of homomorphisms among a set of graphs. This includes the study of rigid graphs, which admit only the identity homomorphisms to themselves. Several constructions based on rigid graphs are discussed in this chapter, and many useful examples of

Meaningful Composite Structures
2008UML2 composite structures are a natural solution for the basic modeling issues associated with component-oriented approaches. They provide mechanisms for defining reusable "pieces" of design, which are well-encapsulated through explicit interaction ports. While intuitive in principle, the semantics of request propagation across ports may cause semantic

Tendon Structure and Composition
2016Tendons are soft, fibrous tissues that connect muscle to bone. Their main function is to transfer muscle generated force to the bony skeleton, facilitating movement around a joint, and as such they are relatively passive, inelastic structures, able to resist high forces.

Rhodizite: Structure and Composition
Science, 1966The mineral rhodizite could not be assigned a chemical formula on the basis of chemical analyses. The solution of the crystal structure reported here reveals that CsB 12 Be 4 Al 4 O 28 is the ideal formula.

The Composition and Structure of the Comic
Journal of Quantitative Linguistics, 2009Abstract In a previous article published in the Journal of Quantitative Linguistics in 2008, I showed how the structure of a comic might be studied mathematically by reducing it to a sequence of binary symbols. Here I show how this binary nature leads to the discovery of a new quantitative law on the composition of comics, which in turn will facilitate,

On the Composition of Well-Structured Programs
ACM Computing Surveys, 1974In diesem Artikel beschreibt Niklaus Wirth im Wesentlichen, was strukturierte Programmierung bedeutet und wieso sie der rein Performance-orientierten Programmierung vorzuziehen sei. Als Ausgangspunkt nimmt er die rasante Entwicklung von Computern. Bis Anfang der 60er Jahre war es laut Wirth noch notwendig, alle denkbaren Programmiertricks anzuwenden ...

Advanced composites for structures.
Journal of Aircraft, 1965The Air Force Advanced Development program on high-modulus filaments and composites involves a comprehensive and integrated effort; it involves not only materials development but simultaneous and heavy emphasis on design and fabrication. It includes, as an essential ingredient, the conclusive demonstration of the value of the technology in the product ...

Seeds are very diverse in their shape and size. In the mature state they contain an embryo, the next generation of plant, surrounded by a protective structure (the seed and/or fruit coat) and, in species in which the nutritive reserves are not stored within the cotyledons, by an alternative storage tissue (endosperm, perisperm, or megagametophyte ...
