The thermomechanical and deformation properties of fibrous heat-insulation refractories

Conclusions An analysis was carried out of the deformation characteristics in uniaxial compression and of the creep and compression strength at temperatures of 400–1100°C of heat-insulation slabs produced from kaolin wool and an organic adhesive.The impregnation with an organic adhesive reduces the deformation of the slabs at temperatures of 20–600°C to a significant extent.The kaolin wool heat-insulation slabs can be used as compensation and construction material for the regenerations of blast furnaces including large-capacity furnaces because the slabs are capable of supporting long-term loads up to 1 kg/cm² at temperatures of 20–1100°C.Translated from Ogneupory, No. 7, pp. 51–54, July, 1976.     

Multistream Articulatory Feature-Based Models for Visual Speech Recognition

We study the problem of automatic visual speech recognition (VSR) using dynamic Bayesian network (DBN)-based models consisting of multiple sequences of hidden states, each corresponding to an articulatory feature (AF) such as lip opening (LO) or lip rounding (LR). A bank of discriminative articulatory feature classifiers provides input to the DBN, in the form of either virtual evidence (VE) (scaled likelihoods) or raw classifier margin outputs. We present experiments on two tasks, a medium-vocabulary word-ranking task and a small-vocabulary phrase recognition task. We show that articulatory feature-based models outperform baseline models, and we study several aspects of the models, such as the effects of allowing articulatory asynchrony, of using dictionary-based versus whole-word models, and of incorporating classifier outputs via virtual evidence versus alternative observation models.
