Many application domains involve constraints that, at a conceptual modeling level, apply to one or more schema paths, each of which involves one or more conceptual joins (where the same conceptual object plays roles in two relationships). Popular information modeling approaches typically provide only weak support for such join constraints. This paper contrasts how join constraints are catered f...

The commutation relations between the generalized Pauli operators of N -qudits (i. e., N p-level quantum systems), and the structure of their maximal sets of commuting bases, follow a nice graph theoretical/geometrical pattern. One may identify vertices/points with the operators so that edges/lines join commuting pairs of them to form the so-called Pauli graph PpN . As per two-qubits (p = 2, N ...

Template polyhedra generalize weakly relational domains by specifying arbitrary fixed linear expressions on the left-hand sides of inequalities and undetermined constants on the right. The domain operations required for analysis over template polyhedra can be computed in polynomial time using linear programming. In this paper, we introduce the generalized template polyhedral domain that extends...

An intention of MapReduce Sets for Reduce side join part file expressions analysis has to suggest criteria how Reduce side join part file expressions in Reduce side join part file data can be defined in a meaningful way and how they should be compared. Similitude based MapReduce Sets for Reduce side join part file Expression Analysis and MapReduce Sets for Assignment is expected to adhere to fu...
