The present book provides the applications of uncertain measures to the field of queueing theory for measuring variations in steady and non-steady birth-death process. Moreover, we have given the applications of probabilistic measures by studying the maximum entropy principle. Another field of interest is the theory of coding which deals with probability distributions only but we have extended the idea to fuzzy distributions by proving new fuzzy coding theorems corresponding to the well-known measures of weighted fuzzy entropy. The book also deals with the applications of measures of entropy for the study of contingency tables and thus provides applications to the field of statistics. I sincerely hope that the present volume of the book will be useful to all those interested in information measures and their applications in a variety of disciplines. Moreover, it will be a source of inspiration and encouragement to research scholars and teachers to discourse the subject for the discovery of new insights.
