Accurate approach in simulating the electronic absorption cross section of small to medium molecules
Sulfuric acid (H2SO4) is the dominant form of atmospheric sulfur in the stratosphere and plays an important role in terms of aerosol formation.The Absorption spectrum of sulfuric acid is simulated. Also in this work three photodissociation mechanisms of H2SO4 are calculated and found significant
Some Epistemic Extensions of G\"odel Fuzzy Logic
In this paper, we introduce some epistemic extensions of G\"odel fuzzy logic
whose Kripke-based semantics have fuzzy values for both propositions and
accessibility relations such that soundness and completeness hold. We adopt
belief as our epistemic operator, then survey some fuzzy implications to
justify our semantics for belief is appropriate. We give a fuzzy version of
traditional muddy children problem and apply it to show that axioms of positive
and negative introspections and Truth are not necessarily valid in our basic
epistemic fuzzy models. In the sequel, we propose a derivation system as
a fuzzy version of classical epistemic logic . Next, we establish some other
epistemic-fuzzy derivation systems and which are
extensions of , and prove that all of these derivation systems are sound
and complete with respect to appropriate classes of Kripke-based models
