The patchy models need not be considered if only susceptibles disperse among patches.
3 The set of activities specified in the pedagogical model need not take place within the adaptive system proper.
However, the resulting model need not be of a proper SEA form, and in particular the indirect coupling loss factors may not be negligible.
First, we apply the pseudo-steady-state assumption and investigate the conditions under which the two-stage model need not be assumed.
Therefore, a model need not be simply a smaller prototype of the real thing; it may use words, pictures, or any combination of media.
This sharing of geometry means that the proxy models need not to be loaded separately for each actor in a scenario, thereby reducing the system and video card memory footprint.
More recently, there has been a growing understanding of the variety of conceptual commitments held by users of such models, especially that the use and development of an optimality model need not bind the user to a blind acceptance of the claim that natural selection is all powerful.
Indeed, the numerical model requires high calculation time; conditions of use of the simplified models are limited, and experimental models need not only important financial resources but also a perfect control of experimental devices (e.g. scale model), as well as climatic characteristics of the location (e.g. in situ experiment).
Developing such a model need not be entirely a matter of logic, but according to one school of thought, logic has a central role to play in it; see, for instance, Baral & Gelfond 2000, Wobcke et al. 1998, Rao & Georgeff 1991, Burkhard et al. 1998).
Calvin Klein models need not be worried.
