Muito tem sido dito acerca da crescente necessidade das organizações serem flexíveis e dinâmicas. Para conseguir este dinamismo, as organizações têm que se estruturar internamente em torno de elementos flexíveis e dinâmicos e dotar-se de mecanismos que assegurem a coerência e o alinhamento entre os vários elementos, que a compõem, à medida que estes se vão modificando. Como exemplo de elementos...

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to “programmatic” charm physics such as spectroscopy, lifetimes, and tests of QCD, this “Charm2000” experiment will have significant sensitivity to new ph...

The Image Reduction and Analysis Facility is a scientific image processing package widely used throughout the astronomical community. IRAF has been developed and distributed by the National Optical Astronomy Observatory in Tucson, Arizona since the early 1980’s. Other observatories and projects have written many dozens of layered external application packages. More than ten thousand journal art...

JPEG2000 is the new standard for the compression of still images. Its objective and subjective image quality performance is superior to existing standards. In this paper the Part I of the JPEG2000 standard is presented in brief, and its implementation complexity on different computer platforms is reported.

In the terms of operational calculus the probability characteristics of direct and reverse residual renewal time of alternating renewal process, where renewal time depends on life-time, are found. 1. Definitions, Motivations and Formulation of the Problem 1.1 According to [1] let’s consider a system which fails after random life-time X1 and is fully renewed after the lapse of random time Y1. Th...

Despite the enormous media coverage that the issue of year 2000 (Y2K) readiness has received in recent months, the focus of that coverage has been restricted almost exclusively to technological aspects. Non-technical issues have tended to be either ignored completely or given very little attention. Most importantly, not much is known about the organisational processes of preparing to face this ...

This document is intended for people who want to “be aware” of some of the mechanisms underlying the JPEG2000 image compression standard [2]. While writing this tutorial my objective was to give to the reader the feeling of what goes on when compressing images with JPEG2000 . Hence, this tutorial should be regarded as introductory material which requires further reading to reach a deeper unders...

In this paper, we investigate the error resilience properties of JPEG2000. Through a careful analysis of the structure of JPEG2000 codestreams, we identify the dependencies among coding passes of a codeblock. In our analysis, we consider the effects of mode variations provided by the standard for low-memory, low-complexity implementations. The proposed methods are derived using the existing dep...

In order to represent the variety of sounds a musical instrument may produce, it is necessary to find a model that can cope with sound features independent from its scale. In this work, several models of timbre characterization were applied to sample notes in several intensity levels across the whole extension of a clarinet. These models were based on amplitude and frequency time-varying curves...
