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 ...

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...

Sociedade Brasileira de Cirurgia Cardiovascular (SBCCV), Dr. Meryt Zanini, the Editorial Assistant Camila Sáfadi and I participated in the IX WORKSHOP OF SCIENTIFIC EDITING, a specific event for Scientific Editors and professionals working with Scientific Journals in our country. Among the topics discussed, the concern with the financial maintenance of scientific journals was at the top of the ...

As we step into the new year of 2014, the Hong Kong Medical Journal (HKMJ) is having a new look. The previous design was used for seven years and the Editorial Board believed that the journal warranted a new dress in this new year. We spent a lot of time designing the new journal cover that you have received in this issue. It incorporates a modern and clean design; more white space is created, ...

The Brazilian Journal of Physical Therapy (BJPH) has consolidated its course, continuously reaching for new goals. Its achievements are the result of intense work and commitment on the part of many professionals who, under the guidance of competent chief editors in line with the Journal’s objectives, conquered the status it holds today as the main periodical in its field, not only in Brazil, bu...
