Dialogues on the New Physics
Eurythmic physics seeks to unify physics for a clearer view of nature. This book develops this approach, arguing that because physical phenomena are not linear, they must be understood from a nonlinear, interrelated, and complex perspective.
Energy and Humanity
This book describes human civilization from an energy perspective, showing how mastering energy catapulted our species to supremacy. It weaves a fascinating story from Stone Age tools to climate change, discussing the dark side and the future of renewables.
This book challenges the idea of progress that treats nature as an inexhaustible resource. It proposes a revolutionary alternative: harmonious progress that respects nature’s boundaries, defining a clear action plan using renewable energy, smart grids, and green settlements.
The triple bottom line is a framework for achieving economic and social balance while maintaining ecological systems. This volume details the state of the art of this approach, indicating where there is debate, overlooked theory, and unresolved problems.
This book presents research on the mathematical modelling of the blast furnace process. It describes models for gas dynamics, heat transfer, and reduction, detailing an analytical study method that complements experimental work. Includes solutions to practical smelting problems.
Membrane technology is a sustainable, low-energy solution for water treatment, but its implementation is hampered by inadequate process modeling. This book focuses on using models as a mathematical background to design, analyze, and optimize these crucial processes.
This book provides a self-contained and accessible introduction to dynamical systems and differential geometry via MAPLE. It is suitable for graduate and advanced students in mathematics, engineering, and physics for both self-study and teaching a semester-long course.
Unconventional Aeronautical Investigatory Methods
The 1972 crash of Alitalia flight AZ 112 killed 115 people and was blamed on pilot negligence. This book reveals the truth: the disaster was not an accident but a criminal act, a symptom of the geopolitical tensions gripping Italy and Europe in that decade.
Digital transformation has changed marketing, but its impact on consumer behaviour still requires exploration. This book sheds light on the challenges and solutions for companies, investigating customer experience, influencer marketing, and trust for the online consumer.
This collection of essays tackles classic questions: What is life? What is consciousness? It explores whether evolution is predetermined, if science and spirituality can harmonize, and if AI is at odds with the human spirit. Each chapter includes science fiction stories on AI.
This book presents a complex approach to material composition determination using joint X-ray spectra of fluorescence, scattering, and diffraction. These methods widen the application of X-ray analysis for specialists in solid state physics and students.
This book is a guide to performing uniform broadband measurements with low uncertainty. It discusses radiometric, photometric, color, and LED measurements, and shows how to avoid large errors by standardizing the measurement procedure and using properly selected meters.
For physics scholars and general readers, this book explores the action of ultra-low doses on biological systems. It covers medicinal remedies like homeopathy, the influence of color and form, and the Twin Correlation.
Developments in Management Science in Engineering 2018
This book identifies the main research categories of Management Science in Engineering (MSE), and evaluates and classifies each journal in this field. Developed by leading experts, it is of interest to scientists, researchers, practitioners, engineers, and students.
This book covers the key principles, theories, and applications of information and communication technologies for academic and professional audiences. It explores network architecture, information theory, wireless communications, network security, and optimisation methods.
This book demonstrates why integrating small residential photovoltaics into the public grid is one of the best solutions to our energy problems, with low impact on power systems. It introduces a new concept: simultaneous on/off grid operation with a triple function inverter.
By coupling gravitational and magnetic fields, a normally weak relativistic effect is enhanced. This outward dragging increases the rotational velocities of galaxies, presenting important implications for the missing mass problem in galactic dynamics.
This book introduces gear drive fundamentals and the theoretical background of load capacity. It focuses on strength analyses for metal, sintered, and polymer gears, describing surface pitting, tooth root capacity, and fatigue design approaches with practical examples.
