Consistency algorithms have been proposed for a wide range of applications that include distributed shared memories (DSM), distributed file systems, and databases. Fundamental definitions and operational constraints that are specific for each system do not necessarily translate well to Internet caches. A Web object is consistent if it is identical to the master document at the origin server, at...

Abstract I n this paper, we investigate the existence and the nature of real exchange rate misalignment in Organization of the Petroleum Exporting Countries (OPEC). To do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. The results imply that all OPEC countries have had misalignment -...

We establish the consistency of an algorithm of Mondrian Forest [LRT14, LRT16], a randomized classification algorithm that can be implemented online. First, we amend the original Mondrian Forest algorithm proposed in [LRT14], that considers a fixed lifetime parameter. Indeed, the fact that this parameter is fixed actually hinders statistical consistency of the original procedure. Our modified M...

Detecting malicious peers is a challenging task in peer-to-peer networks due to their decentralized structure and lack of central authority. Trust models can help identify malicious peers by maintaining information about peer relations and interactions. Keeping information about trust relations helps to reduce risks when providing or using services. This paper introduces two consistency concept...

Earlier studies have shown that plate gaps are sometimes unequal in two-zoned low consistency refiners and that unequal gaps render unevenly refined pulp. It is also known that optimisation of plate gap in low consistency refining leads to improved energy efficiency. In this work, trials were made in mill scale in a modern TMP line equipped with a prototype 72 inch TwinFlo low consistency refin...

Motivated by questions in lossy data compression and by theoretical considerations, this paper examines the problem of estimating the rate-distortion function of an unknown (not necessarily discretevalued) source from empirical data. The main focus is the behavior of the so-called “plug-in” estimator, which is simply the rate-distortion function of the empirical distribution of the observed dat...
