We give a theoretical study of the nature of the bifurcations occurring at the oscillation threshold of woodwind instruments, or of physical systems obeying similar non-linear equations of motion. We start from the simplest description of the acoustical behavior these instruments, a mathematical model containing two equations only, one of which is linear but includes delays, while the other is ...

A classic sum rule by Das et al. is extended to seven of the low-energy constants Ki, introduced by Urech, which parameterize electromagnetic corrections at chiral order O(ep). Using the spurion formalism, a simple convolution representation is shown to hold and the structure in terms of the chiral renormalization scale, the QCD renormalization scale and the QED gauge parameter is displayed. Th...

Monte Carlo Simulation (MCS) offers a powerful means for evaluating the reliability of a system, due to the modeling flexibility that it offers indifferently of the type and dimension of the problem. The method is based on the repeated sampling of realizations of system configurations, which however are seldom of failure so that a large number of realizations must be simulated in order to achie...

Reasoning about actions and describing changes caused by the execution of these actions is an idea central to common sense reasoning. Action description languages have been developed to specify the effects and preconditions of actions using a logical framework. However, many of these formalisms suffer from a lack of generality and modularity [McCarthy, 1987]. A new Modular Action Description la...

As an alternative to existing techniques and algorithms, we investigate the merit of the H∞ approach to the linear equalization of communication channels. We first give the formulation of all causal H∞ equalizers using the results of [1] and then look at the finite delay case. We compare the risk sensitive, H∞ equalizer with the MMSE equalizer with respect to both the average and the worst case...
