This book was released on 1974 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic principles and equations of radionavigation systems have been applied to estimate the wind-measuring accuracy of the Loran-C and Loran-D systems. For Loran-C, the equations for the time difference gradients on the spherical earth have been derived, and a simple method of correcting them to give approximate gradients on a spheroidal earth has been given. For Loran-D, the time difference gradients have been calculated using a flat earth approximation. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: The general five-parameter band model for molecular absorptance in the infrared is used in the generation of numerous model variations in order to perform a feasibility analysis of band model representation of the 15-micron CO2 band. The accuracy of the models is evaluated by comparisons with the original line-by-line calculated spectra for vertical paths through a standard inhomogeneous atmosphere. The medium inhomogeneity is taken into consideration through the use of the Curtis-Godson relations, including moment variations. Line intensity effects are studied with actual intensity data averaged over 5/cm and with the use of a temperature-dependent factor. It is concluded that a band model representation may provide sufficient accuracy to be of value in meteorological applications only if the number and phenomenological nature of the band parameters are allowed to vary significantly throughout the band.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis was made of the Satellite Temperature Sounding Technique to determine the extent of temperature errors arising from possible atmospheric CO2 variations. These possible errors are compared to probable ozone-caused errors and to errors resulting from the radiometer uncertainties.

Download or read book Investigation Into Utilization of Loran and Omega Wind finding Systems for Measuring Winds Below an Aircraft written by Bernard D. Weiss and published by . This book was released on 1972 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field tests were made to evaluate the accuracy/resolution relationship of the NAVAID systems (Loran/Omega) for measuring the vertical profile of the wind. Specifically, these tests involve a series of flight comparisons between the AN/FPS-16 radar and the Omega and Loran equipments. These comparisons were performed using balloon-borne radiosondes with the receiving and processing equipment located on the ground. The specific Air Force requirements are for an accuracy of 3 knots with a 2000 ft sensing interval and a fall rate of 1000 ft/min or greater. The Loran equipments were found to be capable of a 1.4 knot accuracy for these conditions, while the Omega equipments provided an accuracy of 4.3 knots. (Author).

Download or read book Use of Services for Family Planning and Infertility United States 1982 written by Gerry E. Hendershot and published by . 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.
