متن کاملSimulation of economic damage at mechanized wheat harvesting in Khuzestan province of Iran
Abstract The aim of this research is to present a simulation model for reducing economic damages of mechanized wheat harvesting in the weather conditions of Khuzestan province and similar areas. The simulated model is composed of three sub-models, for determining of the appropriate working hours, grain losses, and economic sub-model. In order to determine the appropriate working hours, a mathem...
متن کاملFully Mechanized Proofs of Dilworths Theorem and Mirskys Theorem
We present two fully mechanized proofs of Dilworth’s and Mirsky’s theorems in the Coq proof assistant. Dilworth’s Theorem states that in any finite partially ordered set (poset), the size of a smallest chain cover and a largest antichain are the same. Mirsky’s Theorem is a dual of Dilworth’s Theorem. We formalize the proofs by Perles [2] (for Dilworth’s Theorem) and by Mirsky [5] (for the dual ...
