Use Case Diagrams

6 SE CASES - Craig Larman

UML use case diagrams p. 89 Notice that use cases are not diagrams, they are text. Focusing on second-ary-value UML use case diagrams rather than the important use case text is a common mistake for use case novices. Use cases often need to be more detailed or structured than this example, but

Understanding Euro Wiring Diagrams

Wire colors in those diagrams should be labeled with abbreviations you’ll be able to understand. But just in case you run across a diagram with the orig-inal wiring color codes, use the “Wire Colors” key at left to sort things out. By the way, color codes for electrical wiring are defined in DIN 47 002. Circuit, Block & Schematic Diagrams

Feynman diagrams - University of Oxford

We make use of a graphical technique popularised by Richard Feynman1. Each graph { known as a Feynman Diagram { represents a contribution to M fi. This means that each diagram actually represents a complex number (more generally a complex function of the external momenta). The diagrams give a pictorial way to represent the contributions to the ...
