In this paper a comprehensive scaling analysis of the traffic of the four most popular Massively Multiplayer On-line Role Playing Games (MMORPG) is presented. The examined games are World of Warcraft, Guild Wars, Eve Online and Star Wars Galaxies. Both server and client generated traffic are analyzed in details. Our study reveals the basic statistical properties of the investigated games focusi...

A Rectangular to Polar coordinate converter based on scaling free vectoring CORDIC is proposed in this research paper. Polar coordinates are most appropriate for the systems displaying radial symmetry. Here scaling free CORDIC algorithm operating in vectoring mode computes Polar coordinate of input vector i.e. absolute magnitude and phase angle from its rectangular coordinate. Using this algori...

Scaling laws are pervasive in biological systems, found in a large number of life processes, and across 27 orders of magnitude. Recent findings show both biological and engineered motors adhering to two fundamental regimes for the mass scaling of maximum force output. This scaling law is of particular interest for the robotics field as it can affect the design stage of a robot. In this study we...

In Exp. 1, the "protheticity" of the pleasantness of a diverse set of relatively isointensive odorants was estimated using exponents from power functions fitted by an interative least squares procedure between scale values established by (a) magnitude estimation and (b) category rating and rank ordering. In Exp. 2, this procedure was applied to intensity data derived from quarter-log-step volum...

We review a recently developed approach for analyzing time series with long-range correlations by decomposing the signal increment series into magnitude and sign series and analyzing their scaling properties. We show that time series with identical long-range correlations can exhibit different time organization for the magnitude and sign. We apply our approach to series of time intervals betwee...

Introduction: Corrosion and scaling are important factors affecting drinking water quality, causing health and economic problems. This study aimed to investigate the indicators of corrosion and scaling in Rafsanjan drinking water. Materials and Methods: The present descriptive cross-sectional study was conducted in winter 2018 and spring 2019 in Rafsanjan. The 56 samples were randomly taken fr...

Magnitude estimation is a psychophysical scaling technique where the intensity of a stimulus is rated by the assignment of a number. We report on a preliminary investigation on using magnitude estimation for gathering document relevance judgements, as commonly used in test collectionbased evaluation of information retrieval systems. Unlike classical binary or ordinal relevance scales, magnitude...

Many physical and physiological signals exhibit complex scale-invariant features characterized by 1/f scaling and long-range power-law correlations, indicating a possibly common control mechanism. Specifically, it has been suggested that dynamical processes, influenced by inputs and feedback on multiple time scales, may be sufficient to give rise to 1/f scaling and scale invariance. Two example...
