Once the variables, dependent and independent, have been identified and the relationship between them specified, the formal model, in the form of stock and flow diagrams, is drawn up using conventional System Dynamics notation--squares as stocks, pipe-like arrows as flows, circles as auxiliary variables, rhomboids as constants, and links as influences.
In a section called "Native Cultures of Early Europe," an image of flowing circle-and-wave patterns, incised on the stone interior of a Neolithic tomb on the small island of Gavrinis in Brittany, sent me instantly to the Internet to learn more.
Adopted in this unit are some innovative technologies authorized with the national patent of invention, such as the umbrella-shape gas flow circle unit, the flue gas circulation system and the water feeding system, which help to guarantee its operation safety and increase its operation efficiency.
By penetrating meteoric waters to deeper zones, the geothermal system is fed and the fluid flow circle is eventually completed.
In this concept, the premotor cortex is part of both forward and inverse models (Fig. 1C) and closes a loop of information flow circling between premotor, somatosensory and visual areas which could play a key role in social actions [14], [23], [25], [31], [32], particularly in the case of joint actions requiring tight temporal synchrony between cooperative partners.
Fig. 12 Residual bathymetry with respect to the plate cooling model of Stein and Stein (1992) (Korenaga and Korenaga 2008) (gray shade with contour lines just for negative values) and heat flow (colored circles) in the northwestern Pacific.
We study general dynamical and topological behaviors of minimal sets in skew-product circle flows in both continuous and discrete settings, with particular attentions paying to almost periodically forced circle flows.
In the stock and flow diagram, system dynamics standard notation is used: stock variables are represented as squares, flow variables are circles and constants are diamonds.
To me the images seemed to flow in concentric circles.
Information and authority flow in linked circles, with people taking on shifting roles as needed.
So if 'Oceanus' had some secret meaning in early writers, perhaps they may have meant this river that flows in a circle about the earth.
