CHIRON efficiency tests
We have injected a HeNe laser at 543 nm into the science fiber. A set of lenses and a diaphragm (in collimated space) were used after the laser to inject the beam with the correct focal ratio. The diameter of the diaphragm was set to 4 mm, while the focal length of the focusing lens was 19 mm, which gives an input focal ratio (IFR) of F/4.75. After aligning the fiber in x, y and z directions, w...
متن کاملBiform Theories in Chiron
An axiomatic theory represents mathematical knowledge declaratively as a set of axioms. An algorithmic theory represents mathematical knowledge procedurally as a set of algorithms. A biform theory is simultaneously an axiomatic theory and an algorithmic theory. It represents mathematical knowledge both declaratively and procedurally. Since the algorithms of algorithmic theories manipulate the s...
متن کاملChiron: A Multi-Paradigm Logic
Chiron is a derivative of von-Neumann-Bernays-Gödel (nbg) set theory that is intended to be a practical, general-purpose logic for mechanizing mathematics. It supports several reasoning paradigms by integrating nbg set theory with elements of type theory, a scheme for handling undefinedness, and a facility for reasoning about the syntax of expressions. This paper gives a quick, informal present...
