1. The notation parallels the idea of Penrose graphical notation and Feynman diagrams. 2. Nevertheless, most of the statecharts semantics are heavily biased toward graphical notation . 3. Bryars improvised extensively as Phillips original score was primarily a piece of graphical notation . 4. His scores are mostly prose based, though often employ a graphical notation language also. 5. All the pieces feature various forms of graphical notation and are exclusively composed for live performance. 6. Due to this structure, a different graphical notation to denote the Feynman diagrams can be used. 7. In this context, they are sometimes called birdtracks, tensor diagrams, or Penrose graphical notation . 8. These diagrammatic languages can be traced back to Penrose graphical notation , developed in the early 1970s. 9. The standard notation, with its graphical notation , is better in representing the duration and timing among multiple notes. 10. A system of diagram conventions may evolve into a mathematical notation for example, the Penrose graphical notation for tensor products.
