62Anti-spam techniques — To prevent e mail spam (aka unsolicited bulk email), both end users and administrators of e mail systems use various anti spam techniques. Some of these techniques have been embedded in products, services and software to ease the burden on users… …
63Entropy (information theory) — In information theory, entropy is a measure of the uncertainty associated with a random variable. The term by itself in this context usually refers to the Shannon entropy, which quantifies, in the sense of an expected value, the information… …

65Cumulative frequency analysis — is the applcation of estimation theory to exceedance probability (or equivalently to its complement). The complement, the non exceedance probability concerns the frequency of occurrence of values of a phenomenon staying below a reference value.… …
66Phase field models — A phase field model is a mathematical model for solving interfacial problems. It has been mainly applied to solidification dynamics, [ [http://arjournals.annualreviews.org/doi/abs/10.1146/annurev.matsci.32.101901.155803 WJ. Boettinger et al.… …
