ABSTRACT Estimation of mineral resources and reserves with low values of error is essential in mineral exploration. The aim of this study is to estimate and model a vein type deposit using disjunctive kriging method. Disjunctive Kriging (DK) as an appropriate nonlinear estimation method has been used for estimation of Cu values. For estimation of Cu values and modelling of the distributio...

Some kinds of decompositions of r-disjunctive languages on an arbitrary alphabet will be investigated. We will show that an f-disjunctive (t-disjunctive) language can be divided into two parts and either one part of them is an f-disjunctive (t-disjunctive) language or both parts are r-disjunctive but not f-disjunctive (t-disjunctive) languages. Finally, a relevant result of H. J. Shyr and S. S....

This paper examines how intonation affects the interpretation of disjunctive questions. The semantic effect of a question is taken to be three-fold. First, it raises an issue. In the tradition of inquisitive semantics, we model this by assuming that a question proposes several possible updates of the common ground (several possibilities for short) and invites other participants to help establis...
