This document summarizes a range of possible techniques for the repair of continuous media streams subject to packet loss. The techniques discussed include redundant transmission, retransmission, interleaving and forward error correction. The range of applicability of these techniques is noted, together with the protocol requirements and dependencies.

FDA Panel report: January 1998.

T he Cardiovascular and Renal Advisory Panel of the FDA met January 27-28, 1998, to discuss (1) evaluation and use of intravenous inotropic agents in patients with heart failure; (2) liver function test abnormalities with a new AT 1 receptor blocker, tasosartan; and (3) the use of the platelet IIb/IIIa receptor blocker eptifibatide in syndromes of acute cardiac ischemia. Intravenous drugs for t...

The set packing and set covering models are two useful models in integer programming. Sometimes, due to the special structure of the constraint matrix, the natural linear programming relaxation yields an optimal solution which is integral, thus solving the problem. Perfect, ideal and balanced matrices are three classes of constraint matrices with such integrality properties (for the set packing...

We present a survey of connuence properties of (acyclic) term graph rewriting. Results and counterexamples are given for diierent kinds of term graph rewriting: besides plain applications of rewrite rules, extensions with the operations of collapsing and copying, and with both operations together are considered. Collapsing and copying together constitute bisimilarity of term graphs. We establis...
