Computer simulations had been around since the nineteen-fifties, when military planners, climatologists, and economic forecasters began programming models of particular scenarios and dynamics, and using them to predict outcomes.
Versions of the semantic conception differ in their views about the character of models, sometimes taking models to be abstract mathematical structures, susceptible to precise formal specifications, and sometimes taking them to be more concrete (as chemists do, for example, when they build models of particular molecules).
The company provides porcine models of particular diseases, models that are used to develop gene-based treatments and drugs.
In the latter case, some analytical models of particular performances have been presented.
A computational methodology for instantiating models of particular kinds of language in terms of extracted word frequencies and variational analysis using singular value decomposition.
Domain-specific primitives are designed specifically to support modeling of particular aspects of the topic of study, for example, kinematics or ecology.
The isoalpha points have been detected by the use of the models of particular mechanisms with and without ∂α/∂E parameter included or through different alpha values introduction.
Because leptokurtic (centrally peaked and long-tailed) kernels are common in nature and have important effects in models, of particular interest are families of dispersal kernels in which the degree of leptokurtosis can be varied parametrically.
MR images have been used to construct structural models of particular porous media within which several simulations of mercury intrusion and retraction have been performed with variations in the mechanism for the 'snap-off' of the mercury menisci.
Graph models of particular interests include de Bruijn and string graphs in either directed or bidirected forms.
