Doppler Applications in LEO Satellite Communication Systems develops and presents an important class of techniques useful in the construction of little Low Earth Orbit (LEO) satellite communication systems. It centers on the very significant Doppler shift that attends communications through a LEO satellite and shows how this phenomenon can be exploited for an unexpected benefit. The techniques taught in the book are expected to be particularly attractive to system engineers because ground-based transceivers must generally compensate for the large Doppler component and therefore the necessary receiver processing loops are often already in place and expensed. This volume starts with a recounting of the characteristics of a LEO satellite and its orbit. The 2nd chapter addresses the LEO orbital geometry and reviews the Doppler effect attending LEO communications. Chapter three is focused on the important task of estimating the Doppler at a ground terminal. Appropriate signal processing algorithms are reviewed. Chapter four is concerned with predicting LEO satellite visibility. Chapters five and six are, respectively, devoted to the use of the significant LEO Doppler as an aid in a new traffic flow control protocol and as an aid for effecting communications power control. The last chapter describes MATLAB?? based analysis and demonstration CD-Rom software that accompanies the book. The software is, first, a collection of functions useful for calculating satellite orbits, terrestrial contours and regions, and coordinate transformations based on Earth rotation. They are functions that have proven fundamental to the analysis of the traffic flow control protocol described in the book. Second, the software includes a set of user-friendly graphical animation routines that aid in visualization of a LEO orbit, its coverage regions, and the protocol. Doppler Applications in LEO Satellite Communication Systems provides a thorough review of the LEO Doppler phenomenon and, together with included CD-Rom software, provides the know-how and show-how to harvest the benefits of this unexpectedly useful feature.

Statistical distributions are important tools to model the characteristics of data sets such as right or left skewness, bi-modality or multi-modality observed in different applied sciences such as engineering, medicine, and finance, among others. The well-known distributions such as normal, Weibull, gamma, Lindley are extensively used because of their simple forms and identifiability properties. However, mostly in the last decade or so, researchers have focused on the more complex and flexible distributions, referred to as Generalized or simply G families of distributions to increase the modeling ability of these distributions by adding one or more shape parameters. The main aim of this edited book is to present new development currently made by various researchers in the field of G families of contributions distributions. The book will help future and current researchers in the field of this research. Some of the objectives are listed below: Develop new univariate continuous and discrete G families of probability distributions. Develop new bivariate continuous and discrete G families of probability distributions. Derive useful mathematical properties such as, ordinary and incomplete moments, moments generating functions, residual life and reversed residual life functions, order statistics, quantile spread ordering and entropies, among others and some bivariate and multivariate extensions of the new and existing models using a simple type copula such as: Farlie Gumbel Morgenstern copula. Modified Farlie Gumbel Morgenstern copula. Clayton copula. Renyi entropy copula. Ali-Mikhail-Haq copula. haracterize the models via several techniques such as: the conditional expectation. the truncated moment. the hazard functions. Mills ratio. certain functions of the random variable. the 1st order statistic. the conditional expectation of the record values. Assess the performance of the used estimation methods via Monte-Carlo simulation studies. Show the wide importance and the flexibility of the new models against the competitive models. Construct some new regression models based on the new proposed G families and use in statistical prediction. Application of many new useful goodness-of-fit tests for right censored validation such as the Nikulin-Rao-Robson goodness-of-fit test, modified Nikulin-Rao-Robson goodness-of-fit test, Bagdonavicius-Nikulin goodness-of-fit test and modified Bagdonavicius-Nikulin goodness-of-fit test to the new families.

Microorganisms are responsible for the manufacture of various foods of man. The biochemical reactions of microorganism helps in the process of production of foods. Microorganisms helps in several industries like medicine industry, jute industry. Hormones, Vitamins, Vaccines are also manufactured from microorganisms. They also used in Recombinant technology, cell fusion technology etc. In recent years the role of microorganisms in various industries issue has been found a major importance and there is a potentials for future development. Hence the branch fermentation technology developed into a independent modern branch of science.
