Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work is to study the solution of a 2-D compressible viscous fluid flow in a nozzle on a Hypercube. The analysis of the physical problem on a serial computer and an outline of its parallelization on the hypercube were previously detailed. This paper will detail all the steps of the parallelization and our results: speedups, efficiencies and communication time versus arithmetic time. Keywords: Two dimensional flow, Viscous flow, Nozzle flow, Compressible flow.

Available in PDF, EPUB and Kindle. Book excerpt: We are studying here the numerical simulation of high Reynolds number internal, 2-D flow in a convergent-divergent nozzle, for a compressible, viscous fluid. An implicit finite-difference scheme is used to solve the parabolic approximation of the Navier-Stokes equations, so that the time steps are not severely limited by the small grid sizes needed for the computation of the viscous effects. After the resolution of this problem on a serial computer, we describe the first steps of the parallelization of this problem on a Hypercube (parallel version of the ADI method.

This book was released on 1997 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The PASA Workshops aim to build a bridge between theory and practice in the area of parallel systems and algorithms. Practical problems which require theoretical investigations as well as the applicability of theoretical approaches and results to practice are discussed. A particularly important aspect is the communication and exchange of experiences between various groups working in various areas of parallel computing, e.g. computer science, electrical engineering, physics and mathematics. This volume discusses many aspects of parallel computing from a theoretical as well as a practice-oriented point of view. It shows that there are a number of promising approaches for the application of formal methods to the solution of practical problems in the area of parallel systems and algorithms."--Publisher's website

This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.
