Type Destructors
We study a variant of System F≤ that integrates and generalizes several existing proposals for calculi with “structural typing rules.” To the usual type constructors (→,×, All, Some, Rec) we add a number of type destructors, each internalizing a useful fact about the subtyping relation. For example, in F≤ with products every closed subtype of a product S× T must itself be a product S ′× T′ with...

متن کاملThe Pyrolysis of Refuse Components
During the heating of organic refuse out of contact with air, water, gases and liquids are evolved, leaving a char residue. Ten refuse components from domestic waste were distilled on a laboratory scale, the gaseous products were analyzed and the yields determined. The gases included mainly CO2, CO, H2, CH4, with mixture calorific values of 300 400 Btu per standard cu ft. The yield weights were...
