متن کاملRepeated Columns and an Old Chestnut
Let t > 1 be a given integer. Let F be a family of subsets of [m] = {1, 2, . . . ,m}. Assume that for every pair of disjoint sets S, T ⊂ [m] with |S| = |T | = k, there do not exist 2t sets in F where t subsets of F contain S and are disjoint from T and t subsets of F contain T and are disjoint from S. We show that |F| is O(mk). Our main new ingredient is allowing, during the inductive proof, mu...
متن کاملPerformance on an Orchard Replant Site: An 11-year Summary
High-density apple (Malus domestica) orchard management techniques and productivity were evaluated on an old orchard replant site in North Carolina. Trees were planted at 5 × 10 ft (1.5 × 3.0 m), giving a tree density of 871 trees/acre (2152 trees/ha). Well-branched ‘Smoothee Golden Delicious’ trees on ‘Mark’ rootstock were planted in 1990. Orchard-management factors which increased cumulative ...
متن کاملHerpetofaunal assemblages of a lowland broadleaf forest, an overgrown orchard forest and a lime orchard in Stann Creek, Belize
Understanding and monitoring ecological impacts of the expanding agricultural industry in Belize is an important step in conservation action. To compare possible alterations in herpetofaunal communities due to these anthropogenic changes, trapping arrays were set in a manicured orchard, a reclaimed orchard and a lowland broadleaf forest in Stann Creek district at Toucan Ridge Ecology and Educat...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
