This book discusses an efficient random linear network coding scheme, called BATched Sparse code, or BATS code, which is proposed for communication through multi-hop networks with packet loss. Multi-hop wireless networks have applications in the Internet of Things (IoT), space, and under-water network communications, where the packet loss rate per network link is high, and feedbacks have long delays and are unreliable. Traditional schemes like retransmission and fountain codes are not sufficient to resolve the packet loss so that the existing communication solutions for multi-hop wireless networks have either long delay or low throughput when the network length is longer than a few hops. These issues can be resolved by employing network coding in the network, but the high computational and storage costs of such schemes prohibit their implementation in many devices, in particular, IoT devices that typically have low computational power and very limited storage. A BATS code consists of an outer code and an inner code. As a matrix generalization of a fountain code, the outer code generates a potentially unlimited number of batches, each of which consists of a certain number (called the batch size) of coded packets. The inner code comprises (random) linear network coding at the intermediate network nodes, which is applied on packets belonging to the same batch. When the batch size is 1, the outer code reduces to an LT code (or Raptor code if precode is applied), and network coding of the batches reduces to packet forwarding. BATS codes preserve the salient features of fountain codes, in particular, their rateless property and low encoding/decoding complexity. BATS codes also achieve the throughput gain of random linear network coding. This book focuses on the fundamental features and performance analysis of BATS codes, and includes some guidelines and examples on how to design a network protocol using BATS codes.

Critical coding techniques have developed over the past few decades for data storage, retrieval and transmission systems, significantly mitigating costs for governments and corporations that maintain server systems containing large amounts of data. This book surveys the basic ideas of these coding techniques, which tend not to be covered in the graduate curricula, including pointers to further reading. Written in an informal style, it avoids detailed coverage of proofs, making it an ideal refresher or brief introduction for students and researchers in academia and industry who may not have the time to commit to understanding them deeply. Topics covered include fountain codes designed for large file downloads; LDPC and polar codes for error correction; network, rank metric, and subspace codes for the transmission of data through networks; post-quantum computing; and quantum error correction. Readers are assumed to have taken basic courses on algebraic coding and information theory.

This version of the Laws of Cricket - Simplified is based on the 2nd edn 2019 of the 2017 Code of the MCC Laws of Cricket. A new version.written by this author, based on the 3rd edn 2022 is, also, available on Google Playbook. Though the MCC has issued a 3rd edn 2022 which is to come into effect worldwide on 1st Oct 2022, the BCCI, the controlling body for Cricket in India, has decided to continue using the 2017 Code 2nd edn 2019 during the cricket season 2022-23. You will find this book useful if your home Board has not yet migrated to the new version (3rd edn 2022) of the MCC Laws. I am making available this version as an eBook since umpires & cricketers will continue to find this book helpful for understanding the Laws during the coming season, till your home board adopts the new laws. ABOUT THIS BOOK Ever since the 2000 code of the Laws of Cricket was released, and I taught the same at the MCA entrance level, I have felt that the Laws of Cricket have been drafted in a manner that acommon lay person will be able to comprehend without the guidance of a tutor. The Laws of Cricket, in its present form, is inundated with many cross-references that might, in my view, make the lay reader, the schoolboy; the club cricketer; the budding umpire, shy away from the study of the Laws of Cricket, should he happen to pick up a Law book. I shudder to think how those, whose first or second language is not English, cope with this. With a view to making the Laws of Cricket easily understandable for just these persons, who are at the grassroots of the game, I set about writing this book. This book is based on the 2017 Code, 2nd edition 2019 of the Laws of Cricket. To help in understanding some of the more complex of the Laws, which, at places, have a statement of law & exceptions to it, and exceptions to exceptions, and with cross-references to cross-references, I have included a few charts / tables to help break down some of the more complex Laws into smaller and more easily digestible morsels. Since I have always found it useful to do so, I have highlighted, by underlining, and making bold, certain key phrases and keywords in the Laws, which help the learner to understand it better. Also, certain alerts are provided in the margins, to draw the attention of the reader to critical rules. My efforts are to make the Laws of Cricket more user-friendly. This book does not seek to replace the official Laws of Cricket, the copyright for which is owned by the governing body for the Laws of Cricket, the Marylebone Cricket Club, but to help spread it wider and to penetrate to the grassroots. For any dispute or further study, a reference should be made to the original Laws of Cricket. Though this has made the rephrasing or paraphrasing of the Laws infinitely more difficult, I have retained the original numbering of clauses & sub-clauses, so that the reader can go to the relevant clause in the original Laws of Cricket as and when needed. I recommend that the student-reader have a copy of the ‘Blue-book’ ready when reading my book. I hope the students of the game will find this book useful as also will anyone preparing for an umpiring test at any level. It will be my pleasure to answer any query on the Laws of Cricket sent to [email protected] M. R. Singh

Now, incorporates the amendment made by the MCC on 19.01.2023 Some content is revised as of 24.05.2023, basically, highlighting some aspects. IMPORTANT - Added a table on page A70. ABOUT THE BOOK After the encouraging success of the first book based on the 2017 Code (2nd edn 2019), the author presents this book which incorporates the changes made by the MCC in the 3rd edn 2022. For ease of understanding, these changes are marked in red throughout the book, accompanied by suitable notes & explanations. The original Laws of Cricket are generally seen as presenting quite a challenge for any reader, what with the ‘legalese’ and the long, complex sentences, and the use of several cross-references. ‘The Laws of Cricket – Simplified’, is written for the aspiring young umpire, the schoolgirl/boy, the casual cricketer, the club cricketer, the cricket commentator - even the armchair expert - whose interest in the game might arouse within him/her a desire to pick up a copy of the official Laws of Cricket, and who might be somewhat flummoxed by the intricacies of the Laws. This is an effort to help the lay reader understand the Law, by simplifying the language used and breaking up long sentences. The book is embellished with illustrations, charts & tables in order to break up the more complex Laws for easier understanding. The simplification of the Laws is somewhat limited by my desire to keep its basic structure the same to enable easier look-up in the original Laws in case it is desired. It is hoped that the serious learner might, also, find this book useful, especially the accompanying charts & tables.

Space weather is one of the most significant natural hazards to human life and health. Conditions of the sun and in the solar wind, magnetosphere, ionosphere, and thermosphere can influence the performance and reliability of space-borne and ground-based technological systems. If conditions in the space environment are adverse, they can cause disruption of satellite operations, communications, navigation, and electric power distribution grids, leading to a variety of socioeconomic losses. This book provides an overview of our current knowledge and theoretical understanding of space weather formation and covers all major topics of this phenomena, from the sun to the Earth’s ionosphere and thermosphere, thus providing a fully updated review of this rapidly advancing field. The book brings together an outstanding team of internationally recognised contributors to cover topics such as solar wind, the earth's magnetic field, radiation belts, the aurora, spacecraft charging, orbital drag and GPS.
