The Eternal system provides transparent fault tolerance for CORBA applications, without requiring the modification of either the application or the ORB. Eternal replicates the application objects, and ensures strong replica consistency by employing reliable totally-ordered multicast messages for conveying the IIOP messages of the application. To maintain replica consistency even as replicas fai...

The Eternal system pioneered the interception approach to providing transparent fault tolerance for CORBA, which allows it to make a CORBA application reliable with little or no modification to the application or the ORB. The design and implementation of the Eternal system has influenced industrial practices by providing the basis for the specifications of the Fault-Tolerant CORBA standard that...

The Eternal system provides transparent fault tolerance for CORBA applications, without requiring the modification of either the application or the ORB. Eternal replicates the application objects, and ensures strong replica consistency by employing a reliable totally-ordered multicast protocol for conveying the IIOP messages of the application. To achieve strong replica consistency during recov...

The automated extraction of tempo and beat information from music recordings is a challenging task. Especially in the case of expressive performances, current beat tracking approaches still have significant problems to accurately capture local tempo deviations and beat positions. In this paper, we introduce a novel evaluation framework for detecting critical passages in a piece of music that ar...

The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in te...

How do temporal and eternal beliefs interact? I argue that acquiring a temporal belief should have no effect on eternal beliefs for an important range of cases. Thus, I oppose the popular view that new norms of belief change must be introduced for cases where the only change is the passing of time. I defend this position from the purported counter-examples of the Prisoner and Sleeping Beauty. I...

The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. I describe the quantum origin of density perturbations, giving a heuristic derivation of the scale invariance of the spectrum and the leading corrections to scale invariance. The mechanisms that lead to eternal inflation in both new and chaotic ...

We relate the Eternal Symmetree model of Harlow, Shenker, Stanford, and Susskind to constructions of stochastic processes related to quantum statistical mechanical systems on Cuntz– Krieger algebras. We extend the eternal inflation model from the Bruhat–Tits tree to quotients by p-adic Schottky groups, again using quantum statistical mechanics on graph algebras.

Cosmological inflation, if it occurred, radically alters the picture of the ‘big bang’, which would merely point to reheating at the end of inflation. Moreover, this reheating may be only local so that inflation continues elsewhere and forever, continually spawning big-bang-like regions. This chapter reviews this idea of ‘eternal inflation’, then focuses on what this may mean for the ultimate b...
