In the first part of the paper, the uncertainties on the fundamental data and on the input physics relevant for the computation of the internal structure of the Sun are reviewed. In the second part, I present several tests done in order to compute a solar model with a relative accuracy of 3 x 10−5. I also propose a modification of the difference method which allows to achieve the required accuracy...
A method is presented for the discussion of the details of mode interaction. It is shown that during an interaction, two modes exchange their properties and that the two interacting eigenfunctions are weighted means of the eigenfunctions computed when the interaction in negligible.
Solar models are calculated with low central hydrogen abundance. The stability of these models is investigated. The eigenspectrum is computed and compared with the SCLERA observations of solar oscillation.
We discuss the choice of the difference scheme and of the variables. We also show that a slight modification to the usual difference method allows a significant increase of the accuracy and the computation of, a solar model with a reasonable number of meshpoints.
It is shown that the oscillatory properties of the eigenfunctions can be proved rigorously for the second order problem. Models with discontinuities in density are also considered and “discontinuity modes” are shown to exist. The distribution of amplitudes of these modes is also discussed.
Across North America and worldwide, general internists render care to more than 60% of patients with cardiac problems. In this new edition of the warmly received Heart Disease Diagnosis and Therapy: A Practical Approach, Second Edition, M. Gabriel Khan, MD, concisely assembles in a reader-friendly format all the clinically useful information that internists need in both daily rounds and busy office...
A small but growing niche of clinical practice involves services provided to sexual offenders, typically within the criminal justice system. This is an emotionally, and ethically, challenging area of practice that has, for all practical purposes, been unregulated, with the sole exception of the efforts of one professional organization (Association for Treatment of Sexual Abusers). Given the unusual...
The fully revised second edition of the Encyclopedia of Heart Diseases is an ideal resource for practicing clinicians and researchers. Available in print, online, and with dual access, it is a clear and comprehensive aggregation of the most crucial information and essential data on cardiovascular diseases and therapeutics. Comprised of over 95 entries with regular online updates, the Encyclopedia of Heart Diseases...
While several methods are available and in production for power devices, LED or other markets, 200 mm and 300 mm temporary bonding for 3D integration is a quite new field for material and equipment suppliers and challenging all participants in the supply chain. These paper presents an overview of existing and emerging processes on a flexible equipment platform to match the requirements of the end...
This paper introduces the new MA8 Gen3 Aligner generation designed specifically for the development of 3D and MEMS packaging technologies. Photolithography on the wafer backside, wafer bonding and replication of microstructures are specific 3D / MEMS processes. They have in common that all of them require precision alignment and often will have to run on ultra-thin wafers. The MA8 Gen3 allows to run...
