With the advent of system-on-a-chip design, many application specific integrated circuits (ASICs) now require multiple design clocks that operate asynchronously to each other. This...
Mobile collaborative environments, being naturally loosely-coupled, call for optimistic replication solutions in order to attain the requirement of decentralized highly available ...
Abstract--In communication systems where full-duplex transmission is required, digital echo cancellers are employed to cancel echo by means of adaptive filtering. In order to reduc...
Node lookup mechanisms constitute an integral part of any overlay network, and hence also of anonymous communication networks. Today, most anonymizers use centralized directories, ...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...
