The Complexity of Subtype Entailment for Simple Types
A subtyping 0 is entailed by a set of subtyping constraints C, written C j= 0, if every valuation (mapping of type variables to ground types) that satisfies C also satisfies 0. ...

Eliminating Cycles in the Discrete Torus
In this paper we consider the following question: how many vertices of the discrete torus must be deleted so that no topologically nontrivial cycles remain? We look at two differe...

Global optimization for the synthesis of integrated water systems in chemical processes
In this paper, we address the problem of optimal synthesis of an integrated water system, where water using processes and water treatment operations are combined into a single net...
