Motor-manual operations are commonly implemented in the traditional and short rotation forestry. Deep knowledge of their performance is needed for various strategic, tactical operational decisions that rely on large amounts data. To overcome limitations analytical methods, Artificial Intelligence (AI) has been lately used to deal with types signals problems be solved. However, reliability AI mo...

In this paper, a two-phase evolutionary optimization scheme is proposed for obtaining optimal structure of fuzzy control rules and their associated weights, using evolutionary programming (EP) and the principle of maximum entropy (PME) based on the previous research [1]. 1 Two-Phase Evolutionary Optimization A fuzzy logic controller (FLC) with weighted rules, which is equivalent to a convention...

We point out that the criterion, derived by Long et al.[Phys. Rev A 61, 042305 (2000)], to judging the degree of inaccuracy under systematic errors in phase inversions in Grover’s quantum search algorithm is overestimated. Although this criterion is properly deduced, it lacks a more accurate characterization to the relation between systematic errors and the size of a quantum database. The crite...

L’objectif d’un système largement distribué sur Internet est d’intégrer des participants dont les spécificités et motivations ne sont pas toujours clairement identifiées a priori. En particulier, des participants autonomes peuvent avoir des intérêts individuels spécifiques vis-à-vis des requêtes, mais aussi des autres participants. Dans un tel contexte, un système ne prenant pas en compte les i...

We investigate a particular type of curvaton mechanism, under which inflation can occur at Hubble scale of order 1 TeV. The curvaton is a pseudo Nambu-Goldstone boson, whose order parameter increases after a phase transition during inflation, triggered by the gradual decrease of the Hubble scale. The mechanism is studied in the context of modular inflation, where the inflaton is a string axion....

production planning and scheduling are the most important issues of the production industries, which have a considerable influence on the productivity of the production systems. although, production planning and scheduling are in two different medium-term and short-term decision making levels, there are a very close relationship between them. ignoring this important feature in production planni...

This paper shows how a PDA (Personal Digital Assstant)can be converted into an audio source within a private network or the web, providing capture, compression and streaming of audio as a real-time mobile service. Once the sound around the PDA has been captured and compressed to mp3 format, the service allows it to be broadcast to a Streaming Server. Once the audio reaches the Streaming Server,...

A 20 MHz high density linear array transducer is presented in this paper. This array has been developed using an optimized ceramicpolymer composite material. The electro-mechanical behaviour of this composite, especially designed for high frequency applications , is characterised and the results are compared to theoretical predictions . To support this project, a new method of transducer simula...
