The acoustic transfer admittance of the coupler, including the thermal conductivity effect of the fluid, must be modelled precisely to obtain the accurate sensitivity of the microphones from the electrical transfer impedance measurement.
At the beginning of the process, I was casting about for an appropriate metaphor, and the jigsaw puzzle presented itself as a visual way of representing the million lines of code that piece together all the variables that must be modelled to achieve a realistic, dynamic picture of the global climate.
The real part of the numerically calculated impedance from the FEM simulation is larger because the metallic antenna parts must be modelled as solid aluminium.
In many cases, compression can be considered a necessary simplifying assumption for the modelling exercise, but in other cases, heterogeneity must be explicitly modelled to avoid the phenomenon of confounding.
If parts of a ThermalBoundary have different material properties, especially allowing the transfer of radiation energy, these parts must be separately modelled as ThermalOpening (relation contains).
At present the different types of data must be interpreted separately and the structure modelled iteratively.
The designer of an automatic transcriber must be aware of which musical gestures will be modelled and which will not for example, if the system should either transcribe the tempo swing of a piano player or not.
These theories must be validated employing field data, acquired by means of experiments and observations of the modelled phenomena, before the models can actually be used for sake of prediction.
Similarly, once the problem to be modelled via the ABM is identified, the appropriate set of hypotheses or logic/mathematical rules governing the agents must be developed.
The lifetime costs of ART must therefore be modelled based on assumptions about not just the cost of first line therapy and the number of new infections, but also the effects of ART on longevity, the likelihood of needing to switch to second line drugs, and the other health care costs that are incurred such as management of opportunistic infections.
