Floods constitute a persistent and serious problem throughout the United States and many other parts of the world. They are respon sible for losses amounting to billions of dollars and scores of deaths annually. Virtually all parts of the nation--coastal, mountainous and rural--are affected by them. Two aspects of the problem of flooding that have long been topics of scientific inquiry are flood frequency and risk analyses. Many new, even improved, techniques have recently been developed for performing these analyses. Nevertheless, actual experience points out that the frequency of say a 100-year flood, in lieu of being encountered on the average once in one hundred years, may be as little as once in 25 years. It is therefore appropriate to pause and ask where we are, where we are going and where we ought to be going with regard to the technology of flood frequency and risk analyses. One way to address these questions is to provide a forum where people from all quarters of the world can assemble, discuss and share their experience and expertise pertaining to flood frequency and risk analyses. This is what constituted the motivation for organizing the International Symposium on Flood Frequency and Risk Analyses held May 14-17, 1986, at Louisiana State University, Bat-on Rouge, Louisiana.

After five decades, the field of Statistical Hydrology continues to evolve and remains a very active area of investigation. Researchers continue to examine various distributions, methods of estimation of parameters, and problems related to regionalization. However, much of this research appears in journals and reports and usually in a form not easi

This accessible and comprehensive book provides an introduction to the basic concepts and key circuits of radio frequency systems, covering fundamental principles that apply to all radio devices, from wireless data transceivers on semiconductor chips to high-power broadcast transmitters. Topics covered include filters, amplifiers, oscillators, modulators, low-noise amplifiers, phase-locked loops, and transformers. The author describes applications of radio frequency systems in such areas as communications, radio and television broadcasting, radar, and radio astronomy. The book contains many exercises, and assumes only a knowledge of elementary electronics and circuit analysis. It will be an ideal textbook for junior and senior courses in electrical engineering, as well as an invaluable reference for researchers and professional engineers in this area, or for those moving into the field of wireless communications.

A mainstay of functional linguistics has been the claim that linguistic elements and patterns that are frequently used in discourse become conventionalized as grammar. This book addresses the two issues that are basic to this claim: first, the question of what types of elements are frequently used in discourse and second, the question of how frequency of use affects cognitive representations. Reporting on evidence from natural conversation, diachronic change, variability, child language acquisition and psycholinguistic experimentation the original articles in this book support two major principles. First, the content of people s interactions consists of a preponderance of subjective, evaluative statements, dominated by the use of pronouns, copulas and intransitive clauses. Second, the frequency with which certain items and strings of items are used has a profound influence on the way language is broken up into chunks in memory storage, the way such chunks are related to other stored material and the ease with which they are accessed to produce new utterances.

Frequency plots show patterns in the distribution, or "shape", of data we collect. This guide covers the wealth of information this distribution can provide about a process. It covers what frequency plots are, how to interpret them, and how to create them. Other titles in the 'Plain & Simple' Series include: * Data Collection (7.2 JOI 1) * Pareto Charts (7.2 JOI 3) * How To Graph (7.2. JOI 2) * Flowcharts (7.2. JOI 8) * Frequency Plots (7.2. JOI 6) * Scatter Plots (7.2. JOI 9) * Time Plots (7.2. JOI 7) * Individuals Charts (7.2. JOI 4) * Cause-And-Effect Diagrams (7.2. JOI 5) * Defect Tile Cards and Process Tile Cards.

This book deals with the basic theory for design and analysis of Low Probability of Intercept (LPI) radar systems. The design of one such multi-frequency high resolution LPI radar, PANDORA, is covered. This work represents the first time that the topic of multi-frequency radars is discussed in such detail and it is based on research conducted by the author in The Netherlands. The book provides the design tools needed for development, design, and analysis of high resolution radar systems for commercial as well as military applications. Software written in MATLAB and C++ is provided to guide the reader in calculating radar parameters and in ambiguity function analysis. Some radar simulation software is also included.

The book addresses a controversial current topic in language acquisition studies: the impact of frequency on linguistic structure in child language. A major strength of the book is that the role of input frequency in the acquisition process is evaluated in a large variety of languages, topics and the two major theoretical frameworks: UG-based and usage-based accounts. While most papers report a clear frequency effect, different factors that may be interacting with pure statistical effects are critically assessed. An introductory statement is made by Thomas Roeper who calls for caution as he identifies frequency as a non-coherent concept and argues for a precise definition of what can and cannot be explained by statistical effects.

Scattering theory deals with the interactions of waves with obstacles in their path, and low frequency scattering occurs when the obstacles involved are very small. This book gives an overview of the subject for graduates and researchers, for the first time unifying the theories covering acoustic, electromagnetic and elastic waves.

This book is a comprehensive introduction to the statistical analysis of word frequency distributions, intended for computational linguists, corpus linguists, psycholinguists, and researchers in the field of quantitative stylistics. Word frequency distributions are characterized by very large numbers of rare words. This property leads to strange phenomena such as mean frequencies that systematically change as the number of observations is increased, relative frequencies that even in large samples are not fully reliable estimators of population probabilities, and model parameters that vary with text or corpus size. Special statistical techniques for the analysis of distributions with large numbers of rare events can be found in various technical journals. The aim of this book is to make these techniques more accessible for non-specialists, both theoretically, by means of a careful introduction to the underlying probabilistic and statistical concepts, and practically, by providing a program library implementing the main models for word frequency distributions.
