Promoting Sustainability Through Water Management and Climate Change Adaptation (Advances in Geographical and Environmental Sciences)
by Subhash Anand Anupama Dubey Basavaraj BagadeThis book explores the concept and issues of sustainability and its symbiotic relationship with existing water resources, the surrounding climate and geospatial development. It covers many dimensions of sustainable water resources, climatic variability, change. It also includes case studies on the basis of specific problems and issues, providing sustainable solutions for the future of the earth. Over the past several decades, climate change has significantly impacted a number of components of the hydrological cycle and hydrological systems, including changes in precipitation patterns and intensity; widespread melting of snow and ice; increased atmospheric water vapour; increased evaporation; and changes in soil moisture and runoff. Excess runoff eventually reaches larger bodies of water such as lakes, estuaries and the ocean, contaminating the water supply and limiting human and environmental access to water. An improved understanding of how changing anthropogenic activities could affect water resources, and climate in various parts of the world is a necessary step towards sustainability. This awareness requires analyses of challenging interactive areas within the geosphere, biosphere, hydrosphere, cryosphere and sociosphere, as resultant long-term sustainable strategies and measures are greatly needed.

Proof Technology in Mathematics Research and Teaching (Mathematics Education in the Digital Era #14)
by Gila Hanna Michael De Villiers David A. ReidThis book presents chapters exploring the most recent developments in the role of technology in proving. The full range of topics related to this theme are explored, including computer proving, digital collaboration among mathematicians, mathematics teaching in schools and universities, and the use of the internet as a site of proof learning. Proving is sometimes thought to be the aspect of mathematical activity most resistant to the influence of technological change. While computational methods are well known to have a huge importance in applied mathematics, there is a perception that mathematicians seeking to derive new mathematical results are unaffected by the digital era. The reality is quite different. Digital technologies have transformed how mathematicians work together, how proof is taught in schools and universities, and even the nature of proof itself. Checking billions of cases in extremely large but finite sets, impossible a few decades ago, has now become a standard method of proof. Distributed proving, by teams of mathematicians working independently on sections of a problem, has become very much easier as digital communication facilitates the sharing and comparison of results. Proof assistants and dynamic proof environments have influenced the verification or refutation of conjectures, and ultimately how and why proof is taught in schools. And techniques from computer science for checking the validity of programs are being used to verify mathematical proofs. Chapters in this book include not only research reports and case studies, but also theoretical essays, reviews of the state of the art in selected areas, and historical studies. The authors are experts in the field.
Proof of God: The Shocking True Answer to the World's Most Important Question
by Bernard Haisch Ptolemy TompkinsA Seeker, a Scientist, and the Stunning Answer to the World&’s Oldest Question Ptolemy Tompkins, collaborator on the New York Times bestselling Proof of Heaven and Proof of Angels, is at his lowest point, personally and professionally, when he meets with an astrophysicist with a message for the world: God is real, and science proves it.Proof of God is the unlikely story of how this serious scientist and this broken writer, in a series of conversations stretching over several months, come to understand that the universe—from the smallest sub-atomic particles that make up everything in existence to the farthest reaches of the universe—bears evidence of a creator. In short, God not only exists, but science gives us tools to know this. Proof of God shows how science and religion both point to the same stunning and world-changing truth: God is real.
Proof of Stake: The Making of Ethereum and the Philosophy of Blockchains
by Vitalik ButerinThe ideas behind Ethereum in the words of its founder, describing a radical vision for more than a digital currency—reinventing organizations, economics, and democracy itself in the age of the internet. When he was only nineteen years old, in late 2013, Vitalik Buterin published a visionary paper outlining the ideas behind what would become Ethereum. He proposed to take what Bitcoin did for currency—replace government and corporate power with power shared among users—and apply it to everyday apps, organizations, and society as a whole. Now, less than a decade later, Ethereum is the second-most-valuable cryptocurrency and serves as the foundation for the weird new world of NFT artworks, virtual real estate in the metaverse, and decentralized autonomous organizations.The essays in Proof of Stake have guided Ethereum&’s community of radicals and builders. Here for the first time they are collected from across the internet for new readers. They reveal Buterin as a lively, creative thinker, relentlessly curious and adventuresome in exploring the consequences of his invention. His writing stands in contrast to the hype that so often accompanies crypto in the public imagination. He presents it instead as a fascinating set of social, economic, and political possibilities, opening a window into a conversation that far more of us could be having.Media scholar Nathan Schneider provides introductions and notes.

Propagation Modeling for Wireless Communications
by Indrakshi DeyThis book introduces the various approaches and tools used for modelling different propagation environments and lays the foundation for developing a unified theoretical framework for future integrated communication networks. In the case of each type of network, the book uses basic concepts of physics, mathematics, geometry and probability theory to study the impact of the dimension and shape of the propagation environment and relative transmit-receive position on the information flow. The book provides an introduction into wireless communication systems and networks and their applications. For both systems and networks, the basic hard (encoder, modulator, etc.) and soft components (information, signal, etc.) are discussed through schematic block diagrams. Next each of the modes of communication, namely radio waves, acoustic waves, magnetic induction, optical waves, biological particles (molecules, aerosols, neural synapse etc.) and quantum field, are discussed. For each communication scenario presented, the impact of different environmental factors on the propagation phenomenon is articulated, followed by different channel modelling (deterministic, analytical, and stochastic) techniques that are used to characterize the propagation environment. Finally future trends in wireless communication networks are examined and envisioned for next generations 6G/7G of communication systems, like space information networks, sea-to-sky internet of vehicles, and internet of bio-nano things. Based on the future trends of integrated networks, the book drives the need for a generalized channel model irrespective of the media and mode of information transfer. The primary audience for the book is post-graduate students, researchers and academics in electronics and communications engineering, electrical engineering and computer science.

Properties and Characterization of Modern Materials
by Andreas Öchsner Holm AltenbachThis book focuses on robust characterization and prediction methods for materials in technical applications as well as the materials' safety features during operation. In particular, it presents methods for reliably predicting material properties, an aspect that is becoming increasingly important as engineering materials are pushed closer and closer to their limits to boost the performance of machines and structures. To increase their engineering value, components are now designed under the consideration of their multiphysical properties and functions, which requires much more intensive investigation and characterization of these materials. The materials covered in this monograph range from metal-based groups such as lightweight alloys, to advanced high-strength steels and modern titanium alloys. Furthermore, a wide range of polymers and composite materials (e. g. with micro- and nanoparticles or fibres) is covered. The book explores methods for property prediction from classical mechanical characterization-related fields of application, for example, from wear, creep, fatigue and crack growth, to specific surface properties, to dielectric and electrochemical values. As in all fields of modern engineering, the process is often accompanied by numerical simulation and optimization.
