In the definition, MB stands for the modal base of keneng, which can be either epistemic or metaphysical.
Recall that the metaphysical modal base of non-root modals for the past has to do with possible future development of an event relative to a past temporal perspective (i.e., a past temporal perspective combined with a future temporal orientation).
The fact that this third type of attitude conveys a doxastic assertion suggests that it describes an information state which supplies a modal base to embedded epistemic modals.
Epistemic modals, when occurring in embedded contexts, obtain their modal bases from the embedding attitude verbs.
The modal amplitude equations also involve co-ordinates of unknown "lift-off points" determined as a part of the solution for structural response through the constraints imposed on the solution derived by the Galerkin method using linear modal bases.
In the present paper, in order to alleviate inaccuracies in the evaluation of static and quasi-static effects, induced by the truncation of the modal base, an efficient approach to the evaluation of static and quasi-static corrections is developed.
Example 61 shows the truth-conditions of epistemically modalized sentences, in which epistemic modals, when unembedded, make claims with respect to S, the modal base that is assumed to be contextually provided, and the ordering source parameter g (Kratzer 1981 , 1991.
This consideration of the relation between the natural world of God continues throughout the Middle Ages: for example, Duns Scotus' proof of the existence of God is an a posteriori modal proof, based on the notion of causality, and incorporating all of the subtlety of Scotus' analysis of relations between causes (Craig 1980; Normore 2003; Ross and Bates 2003; King 2003).
This work presents a methodology for the design of semi-modal active vibration control of a rectangular plate using modal filters based on arrays of piezoelectric sensors.
Moreover, it allows to extend the applicability of many modal analysis based applications towards the domain of in-operation modal testing.
