This paper addresses the question of CPU performance emulation, which allows experimenters to evaluate applications under a wide range of reproducible experimental conditions. Specifically, we propose Fracas, a CPU emulator that leverages the Linux Completely Fair Scheduler to achieve performance emulation of homogeneous or heterogeneous multi-core systems. Several benchmarks reproducing differ...

We study the palindromic complexity of infinite words uβ , the fixed points of the substitution over a binary alphabet, φ(0) = 01, φ(1) = 01, with a − 1 ≥ b ≥ 1, which are canonically associated with quadratic non-simple Parry numbers β. 1991 Mathematics Subject Classification. 68R15, 11A63 .

Some results are presented of the Earths microseismic background. It is assumed that background peaks should correspond to the resonance gravity-wave exchange in the system of two gravity-connected bodies. The microseismic spectrum is compared with the distribution of gravity potential of the nearest stars. A close peak-to-peak correspondence is found. This correspondence and resonance conditio...

This overview article concerns the notion of fractional smoothness of random variables of the form g(XT ), where X = (Xt)t∈[0,T ] is a certain diffusion process. We review the connection to the real interpolation theory, give examples and applications of this concept. The applications in stochastic finance mainly concern the analysis of discrete time hedging errors. We close the review by indic...

Aldous (2007) defined a gossip process in which space is a discrete N ×N torus, and the state of the process at time t is the set of individuals who know the information. Information spreads from a site to its nearest neighbors at rate 1/4 each and at rate N−α to a site chosen at random from the torus. We will be interested in the case in which α < 3, where the long range transmission significa...
