A linear (qd, q, t)-perfect hash family of size s in a vector space V of order qd over a field F of order q consists of a set S = {1, . . . , s} of linear functionals from V to F ...
We study the fifo and causal multicast problem, two group-communication abstractions that deliver messages in an order consistent with their context. With fifo multicast, the co...
: Database schemas are used to describe the logical design of a database. Diverse groups of users have different perspectives on the schema which leads to different local schemas. ...
Abstract. Logic-based argumentation offers an approach to querying and revising multiple ontologies that are inconsistent or incoherent. A common assumption for logic-based argumen...
In the case of multicomponent AM-FM signals, the idealized representation which consists of weighted trajectories on the time-frequency (TF) plane, is intrinsically sparse. Recent...
