THE PATH OF THE UNREAL AND THE PATH OF THE ABSURD: ON AN EPISTEMIC PREDICATE THAT WE DON'T REALLY MISS

100%

Boguslawski A.

tom 2

5-18

The author examines the question of what logical consequences the formula of an imaginary epistemic structure:Kpa v (~p / ~K~pa) would have (with K standing for the predicate 'know that' which is subject to the axiom Kpa -p); the structure is conceived of as proper to an intended predicate weaker than the predicate know that in ordinary language. A predicate constructed in the indicated way and obviously based on a suitable weakening alternative, would have itself to enter a tautological alternative (in virtue of the respective rudimentary logical requirement applying to all predicates). It appears, however, that the tautological alternative of the would-be predicate and its negation involves dealing with gross absurdities.

Absolute instability of double annular jets: local stability analysis

2021

tom Vol. 73, nr 3

267--300

The paper presents the local linear stability analysis of the double annular jets. The calculations show that the first absolutely unstable helical mode can be generated in the non-swirling annular jets by the back-flow in the central recirculation zone or sufficiently strong back-flow in the external recirculation zone. The influence of the back-flow magnitude on the frequency, growth rate and eigenfunctions of the first helical mode is discussed. The calculations are completed with an analysis of the influence of the swirl intensity in the internal and external jets on the characteristics of the first absolutely unstable helical mode.
