The sintering behaviour of several green compacts made with olivine or olivine/alumina powder blends has been examined. To this goal, powders were attrition milled, uniaxially pressed into specimens and air sintered at temperatures ranging from 1100 to 1300 °C. The resulting samples were characterized by water absorption, shrinkage, phase composition and density. Compositions containing 5%, 10%...

Significance: Part 2 – Development of standards – Reality checks Demonstration ad absurdum: Accepting the premise of prevalent 100/1300 high-energy surges and modeling the response of typical metal-oxide varistors leads to the conclusion that most of the billions of varistors in service should fail at alarming rates – but we know they do not. Ergo, the premise is not valid. This paper was part ...

Non-linear mappings of the form P (ngram)γ and log(1+τP (ngram)) log(1+τ) are applied to the n-gram probabilities in five trainable open-source language identifiers. The first mapping reduces classification errors by 4.0% to 83.9% over a test set of more than one million 65-character strings in 1366 languages, and by 2.6% to 76.7% over a subset of 781 languages. The second mapping improves four...
