Book excerpt: Wanting a baby? Not wanting a baby just now? Nature has provided every woman with a precise signal of her state of fertility, which she can quickly learn to recognise. This simple fact is the basis of the Billings Method, which has helped millions of woman around the world to tune into their own bodies and achieve healthy, natural fertility control. Using the Billings Method you and your partner can be confident of knowing every day whether you are fertile or infertile, and so decide when to make love, depending on wether you want to achieve or avoid pregnancy. This book is a clear guide for all women, whether your cycles are regular or irregular, whether you are coming off the Pill, breastfeeding a new baby, or approaching the menopause. 'This is knowledge of her body that every woman ought to have' DR EVELYN BILLINGS

Download or read book Contraceptive Research and Development written by Institute of Medicine and published by National Academies Press. This book was released on 1996-11-04 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.

Download or read book Nonlinear System Identification written by Stephen A. Billings and published by John Wiley & Sons. This book was released on 2013-07-29 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear System Identification: NARMAX Methods in the Time, Frequency, and Spatio-Temporal Domains describes a comprehensive framework for the identification and analysis of nonlinear dynamic systems in the time, frequency, and spatio-temporal domains. This book is written with an emphasis on making the algorithms accessible so that they can be applied and used in practice. Includes coverage of: The NARMAX (nonlinear autoregressive moving average with exogenous inputs) model The orthogonal least squares algorithm that allows models to be built term by term where the error reduction ratio reveals the percentage contribution of each model term Statistical and qualitative model validation methods that can be applied to any model class Generalised frequency response functions which provide significant insight into nonlinear behaviours A completely new class of filters that can move, split, spread, and focus energy The response spectrum map and the study of sub harmonic and severely nonlinear systems Algorithms that can track rapid time variation in both linear and nonlinear systems The important class of spatio-temporal systems that evolve over both space and time Many case study examples from modelling space weather, through identification of a model of the visual processing system of fruit flies, to tracking causality in EEG data are all included to demonstrate how easily the methods can be applied in practice and to show the insight that the algorithms reveal even for complex systems NARMAX algorithms provide a fundamentally different approach to nonlinear system identification and signal processing for nonlinear systems. NARMAX methods provide models that are transparent, which can easily be analysed, and which can be used to solve real problems. This book is intended for graduates, postgraduates and researchers in the sciences and engineering, and also for users from other fields who have collected data and who wish to identify models to help to understand the dynamics of their systems.

Download or read book Natural Birth Control Made Simple written by Barbara Kass-Annese and published by Hunter House. This book was released on 2003 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives specific instruction on the use of two methods of family planning: Natural Family Planning and Fertility Awareness Method. These methods give couples natural choices: 1. To avoid pregnancy, you can determine when you are infertile and have sexual intercourse without conceiving. 2. To become pregnant, you can track the days of the month when you are most fertile and have intercourse when you are most likely to conceive. 3. These safe non-invasive techniques can be used by themselves or combined with other contraception methods. 4. The techniques are noninvasive, have no side effects and carry no danger of toxic infection or cancer. The authors, experts in fertility awareness, have completely revised and updated this newly titled edition of the book. The new material includes several new examples of natural birth control and the fertility awareness method, with illustrations. The book contains 40 charts for readers to use. The book is written in an accessible style and contains edifying case studies.
