A carry-select adder(CSA) can be implemented by using single ripple carry adder and an add-one circuit instead of using dual ripple-carry adders to reduce the area and power but w...
In this paper, we present a rule-based modelling language for constraint programming, called Rules2CP. Unlike other modelling languages, Rules2CP adopts a single knowledge represen...
Composite (or Complex) event processing (CEP) systems search sequences of incoming events for occurrences of userspecified event patterns. Recently, they have gained more attentio...
One of the previous articles in this column was devoted to the zero-one laws for a number of logics playing prominent role in finite model theory: first-order logic FO, the extens...
Parallelism constraints are logical descriptions of trees. Parallelism constraints subsume dominance constraints and are equal in expressive power to context unification. Paralleli...
