In the frame of the grammatical description “from meaning to form” the author promotes the thesis that arguments implied by verbal predicates stand in the syntactic position primarily designed for noun phrases.
In search of the invariant semantics of the preposition “da”: a cognitive analysis of the predicative context – The purpose of this article is to verify whether the semantic invariant of the preposition da [starting point allowing physical or mental movement] in the nominal context remains valid in the context of the verb. The analysis of the content of predicates that link to the preposition da will help to answer the question of the extent to which the choice of a preposition is determined by the knowledge of the experienced activities and/or the predicate itself (its selective features) or if it is the result of convention.
To investigate the effect of different proximate index on minimum ignition temperature(MIT) of coal dust cloud, 30 types of coal specimens with different characteristics were chosen. A two-furnace automatic coal proximate analyzer was employed to determine the indexes for moisture content, ash content, volatile matter, fixed carbon and MIT of different types of coal specimens. As the calculated results showed that these indexes exhibited high correlation, a principal component analysis (PCA) was adopted to extract principal components for multiple factors affecting MIT of coal dust, and then, the effect of the indexes for each type of coal on MIT of coal dust was analyzed. Based on experimental data, support vector machine (SVM) regression model was constructed to predicate the MIT of coal dust, having a predicating error below 10%. This method can be applied in the predication of the MIT for coal dust, which is beneficial to the assessment of the risk induced by coal dust explosion (CDE).
