This book was released on 2013-04-17 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the description of an EC-sponsered program to study all relevant aspects of shock/ boundary-layer interaction control, the latter designed to improve aircraft performance at design (cruise) and off-design conditions. The work being presented includes a discussion of basic control experiments and the corresponding physical modeling, to account for shock control and a discussion of the airfoil experiments conducted for code validation and control assessment, in conjunction with the basic experiments and computations. The contents is comprised of a section giving a broad overview of the research carried out here and more detailed individual contributions by the participants in the research. Der Band enthält den Abschlußbericht eines von EU geförderten Projekts EUROSHOCK, das alle relevanten Aspekte der Kontrolle von Stoßfronten und Grenzschichten (wichtig z.B. für die Verbesserung der Flugeigenschaften von Fluzeugen) untersuchte. Neben einer ausführlichen Diskussion der grundlegenden Kontrollexperimente und der zugrundeliegenden Modellierung werden auch die Versuche an Tragflächen beschrieben, die zur Validierung von Modellrechnungen durchgeführt werden. Darüber hinaus enthält der Band auch die detaillierten Ergebnisse der Teilnehmer an dem Forschungsprogramm.

This book was released on 2005 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: La présente étude a pour objectif d'analyser les aspects instationnaires de l'interaction transsonique entre une onde de choc oscillante et une couche limite décollée en écoulement de canal. L'oscillation de l'onde de choc est forcée par une évolution périodique de la section d'un col aval, au moyen d'une came elliptique en rotation placée au voisinage de ce col, au milieu du canal. La came en rotation génère des ondes de pression qui vont remonter l'écoulement. La paroi inférieure du canal en forme de bosse va permettre un décollement de l'écoulement. L'évolution du bulbe de décollement pendant le cycle d'oscillation du choc a été quantifiée expérimentalement avec précision. Par les calculs, le cycle d'oscillation du choc est correctement reproduit mais l'extension de la région décollée est toujours sous-estimée. L'impact de techniques de contrôle sur la couche limite et sur l'oscillation forcée de l'onde de choc a été caractérisé. Le contrôle actif a permis de réduire l'oscillation.

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.
