Classification Made Relevant - How Scientists Build and Use Classifications and Ontologies (Paperback): Jules J. Berman Classification Made Relevant - How Scientists Build and Use Classifications and Ontologies (Paperback)
Jules J. Berman
R2,480 Discovery Miles 24 800 Ships in 10 - 15 working days

Classification Made Relevant: How Scientists Build and Use Classifications and Ontologies explains how classifications and ontologies are designed and used to analyze scientific information. The book presents the fundamentals of classification, leading up to a description of how computer scientists use object-oriented programming languages to model classifications and ontologies. Numerous examples are chosen from the Classification of Life, the Periodic Table of the Elements, and the symmetry relationships contained within the Classification Theorem of Finite Simple Groups. When these three classifications are tied together, they provide a relational hierarchy connecting all of the natural sciences. The book's chapters introduce and describe general concepts that can be understood by any intelligent reader. With each new concept, they follow practical examples selected from various scientific disciplines. In these cases, technical points and specialized vocabulary are linked to glossary items where the item is clarified and expanded.

Temporal Data Mining via Unsupervised Ensemble Learning (Paperback, UK ed.): Yun Yang Temporal Data Mining via Unsupervised Ensemble Learning (Paperback, UK ed.)
Yun Yang
R1,173 Discovery Miles 11 730 Ships in 10 - 15 working days

Temporal Data Mining via Unsupervised Ensemble Learning provides the principle knowledge of temporal data mining in association with unsupervised ensemble learning and the fundamental problems of temporal data clustering from different perspectives. By providing three proposed ensemble approaches of temporal data clustering, this book presents a practical focus of fundamental knowledge and techniques, along with a rich blend of theory and practice. Furthermore, the book includes illustrations of the proposed approaches based on data and simulation experiments to demonstrate all methodologies, and is a guide to the proper usage of these methods. As there is nothing universal that can solve all problems, it is important to understand the characteristics of both clustering algorithms and the target temporal data so the correct approach can be selected for a given clustering problem. Scientists, researchers, and data analysts working with machine learning and data mining will benefit from this innovative book, as will undergraduate and graduate students following courses in computer science, engineering, and statistics.

Rethinking the Regulation of Cryptoassets - Cryptographic Consensus Technology and the New Prospect (Hardcover): Syren Johnstone Rethinking the Regulation of Cryptoassets - Cryptographic Consensus Technology and the New Prospect (Hardcover)
Syren Johnstone
R3,827 Discovery Miles 38 270 Ships in 10 - 15 working days

This thought-provoking book challenges the way we think about the regulation of cryptoassets based on cryptographic consensus technology. Bringing a timely new perspective, Syren Johnstone critiques the application of a financial regulation narrative to cryptoassets, questions the assumptions on which it is based, and considers its impact on industry development. Providing new insights into the dynamics of oversight regulation, Johnstone argues that the financial narrative stifles the 'New Prospect' for the formation of novel commercial relationships and institutional arrangements. The book asks whether regulations developed in the 20th century remain appropriate to apply to a technology emerging in the 21st, suggesting it is time to think about how to regulate for ecosystem development. Johnstone concludes with proposals for reform, positing a new framework that facilitates industry aspirations while remaining sustainable and compatible with regulatory objectives. Rethinking the Regulation of Cryptoassets will be an invaluable read for policy makers, regulators and technologists looking for a deeper understanding of the issues surrounding cryptoasset regulation and possible alternative approaches. It will also be of interest to scholars and students researching the intersection of law, technology, regulation and finance.

Blockchain has potential to revolutionize how manufacturers design, engineer, make and scale their products. Blockchain is gradually proving to be an effective "middleware" solution for enabling seamless interoperability within complex supply chains. Due to its technological nature, blockchain enables secure, transparent and fast data exchanges as well as allowing for the creation of immutable records databases The main advantage of Blockchain in Manufacturing Industries is product traceability, supply chain transparency, compliance monitoring, and auditability. Moreover, leveraging blockchain technology into a manufacturing enterprise can enhance its security and reduce the rates of systematic failures. So, blockchain is now used in various sectors of the manufacturing industry, such as automotive, aerospace, defense, pharmaceutical, consumer electronics, textile, food and beverages, and more. Hence, Blockchain should be seen as an investment in future-readiness and customer-centricity, not as an experimental technology - because, the evidence is overwhelming. This book will explore the strengths of Blockchain adaptation in Manufacturing Industries and Logistics Management, cover different use cases of Blockchain Technology for Manufacturing Industries and Logistics Management, and will discuss the role, impact and challenges of adopting Blockchain in Manufacturing industries and Logistics Management. The chapters will also provide the current open issues and future research trends of Blockchain, especially for Manufacturing Industries and Logistics, and will encapsulate quantitative and qualitative research for a wide spectrum of readers of the book.
