The field of random graphs came into existence with papers of Erdos and Renyi in the late 19¿s. From then many researchers have studied different properties of random networks because of its wide application in communication networks, social networks, ad-hoc networks and network security etc. The practical applicability of random graphs continues to grow with the advances in networks models and new challenges imposed by larger and complex networks. This book provides a comprehensive survey of advances in random graphs techniques and shows its application in various fields. This book also includes some of the new results with complete explanation and proof for random graphs with focus on future research and advances. This book is useful for masters and Phd students, as well as researchers and practitioners. However, reader requires basic knowledge of random graphs and probability theory. The book also includes useful references which help readers to understand the topic cover in this book. Also the readers are encouraged to look for other text books for more complete study of the topic. The results presented in this book are published in reputed journals and conferences.

The thesis book M. Sc. (Ag) 2015 -17, the author has provided a sufficiently critical evolution from which one can deduce that work can potentially produce a significant contribution to the subject area because of dairy farming is an integral part of agriculture and rural women playing a significant role in agriculture and contribute one ¿ third of the labor force required for farming and Animal Husbandry related operation. The study was undertaken to know the extent of participation of rural women in the decision-making process in dairy farming in Surguja Districts of Chhattisgarh. The book is divided into seven parts each part dealing with separate aspects and all these parts have been presented in a logical sequence.

Dive into the world of SQL on Hadoop and get the most out of your Hive data warehouses. This book is your go-to resource for using Hive: authors Scott Shaw, Ankur Gupta, David Kjerrumgaard, and Andreas Francois Vermeulen take you through learning HiveQL, the SQL-like language specific to Hive, to analyze, export, and massage the data stored across your Hadoop environment. From deploying Hive on your hardware or virtual machine and setting up its initial configuration to learning how Hive interacts with Hadoop, MapReduce, Tez and other big data technologies, Practical Hive gives you a detailed treatment of the software.In addition, this book discusses the value of open source software, Hive performance tuning, and how to leverage semi-structured and unstructured data. What You Will LearnInstall and configure Hive for new and existing datasetsPerform DDL operationsExecute efficient DML operationsUse tables, partitions, buckets, and user-defined functionsDiscover performance tuning tips and Hive best practicesWho This Book Is ForDevelopers, companies, and professionals who deal with large amounts of data and could use software that can efficiently manage large volumes of input. It is assumed that readers have the ability to work with SQL.
