Quorum-Based Replication in Object-Based Systems
methods. If a pair of methods op1 and op2 are compatible, the summation of the quorum numbers of op1 and op2 can be smaller than the number of replicas in the QOL protocol even if ...

A Lagrangian formulation of Zador's entropy-constrained quantization theorem
Abstract--Zador's classic result for the asymptotic high-rate behavior of entropy-constrained vector quantization is recast in a Lagrangian form which better matches the Lloyd...
