From theCambridge English Corpus We also recall how these entropies are related. From theCambridge English Corpus Recently, the pre-image structure of maps has become deeply characterized via entropies (see [4-9]). From theCambridge English Corpus In particular, it is easy to see that for locally symmetric metrics both entropies coincide. From theCambridge English Corpus The entropies of the two sets of spike trains, which we term "repeated" and "rerandomized," were calculated as a function of time as follows. From theCambridge English Corpus The relations between these entropies are explained. From theCambridge English Corpus The following statement will allow us to estimate the topological entropies of the sets from below, without constructing probability measures, which are invariant and concentrated on a given set. From theCambridge English Corpus Multifractal analysis of local entropies for expansive homeomorphisms with specification. From theCambridge English Corpus Calculations of activation entropies of chemical reactions in solution. From theCambridge English Corpus The topologicalentropy(see [1]) is a well-known quantitative measure of the dynamical complexity of a model. From theCambridge English Corpus Theentropyof a skew product of measure preserving transformations. From theCambridge English Corpus Right-closing factor maps are bounded-to-one and hence preserve topologicalentropy. From theCambridge English Corpus The volumeentropycan be normalized by the volume. From theCambridge English Corpus Other similar bounds on theentropyhave been established in [10] for systolically extremal surfaces (see [16] for a generalization in higher dimension). From theCambridge English Corpus Since the system has finiteentropylog h, the number of cylinders of length n is bounded above by hn (see [6, p. 213]).

From theCambridge English Corpus entropy production In contrast, explicit time discretization, discussed in the next example, leads to entropy production. From theCambridge English Corpus low entropy Clearly, resource prices must eventually reflect an increase in the absolute scarcity of low entropy.
