Semi-Supervised Learning for Neural Keyphrase Generation

, 2018
We study the problem of generating keyphrases that summarize the key points for a given document. While sequence-to-sequence (seq2seq) models have achieved remarkable performance on this task (Meng et al., 2017), model training often relies on large ...

On the use of cryomilling and spark plasma sintering to achieve high strength in a magnesium alloy [PDF]

, 2016
Bulk nanostructured magnesium alloy AZ31 has been produced by spark plasma sintering at four different temperatures from 350 to 450 °C. The effect of sintering temperature on microstructural evolution and compression behaviour was studied in detail.

Superplasticity of Fine-Grained Magnesium Alloy AZ31 Processed by Multi-Directional Forging

MATERIALS TRANSACTIONS, 2007
Superplasticity was studied in a fine-grained magnesium alloy AZ31 processed by multidirectional forging (MDF) under decreasing temperature conditions. Tensile tests were carried out at temperatures from 393 K to 473 K and at various strain rates. Superplasticity appears even at a low temperature of 393 K with a stress exponent of around 5.6 and a ...
