Petr Hájekods. This book has been written to illustrate how calorimetric and spectroscopic measurements can be used to check theoretical predictions on extinction properties of infrared radiation in optically thick, absorbing and scattering particulate media. A determination of infrared extinction coefficient

The natural ordering ≤ of reals will play a very important role; thus our truth values are linearly ordered, the ordering is dense and complete (each set o

Many-Valued Predicate Logics,analogous to the classical predicate logic; in particular, we shall deal only with two quantifiers, ∀ and ∃ (universal and existential). Generalized quantifiers will be studied in later chapters. In Section 1 we shall develop the predicate counterpart BL∀ of our basic propositional logic BL; in Sect
