The dynamic model could be improved by having more physical representations of suspension elements: non-linearity that is associated with the air suspension characteristics, stop dampers on bogie along lateral direction, non-linear force-displacement behavior of conical primary suspensions, effect of leveling valves on secondary air suspension stiffness, etc.
Certainly, the 'bad boy' Beyoncé is in love with is more a physical representation of countless painfully banal fantasies about guys who 'drive too fast' and 'smoke too much' than an actual person, but at least it feels tangible.
Alternatively, and as future work, we might substitute these simple design choices with more realistic physical representations of the cell agents and with adaptive shapes for the cell dynamics by using the sub-element approach [12].
The grey-box model is more flexible: it is a physical representation but with some parts being modelled empirically.
Improved modelling of ice sheets, by use of high resolution and with representation of more physical processes, is constrained by long run-times even on the latest single-processor workstation.
Language could be nothing more than a higher-order instrument of thought: a physical representation of ideas, having no meaning except in relation to them.
For us, it's far more than a reason to decorate a tree - a physical representation of Yggdrasil, the World Tree.
It's nothing more than a small orange thread, but its zigzag shape is a physical representation of my voice frequency.
Redundancy refers to the difference between the physical representation of a message and the mathematical representation of the same message that uses no more bits than necessary.
You're going to do physical representation of number lines.
