Description:

Cyber Insecurity: Examining the Past, Defining the Future deals with the multifaceted world of cybersecurity, starting with the premise that while perfection in cybersecurity may be unattainable, significant improvements can be made through understanding history and fostering innovation. Vladas Leonas shares his journey from Moscow to Australia, highlighting his academic and professional milestones.
This book covers the evolution of cybersecurity from the late 1960s to the present, detailing significant events and technological advancements. The author emphasises the importance of simplicity in technology projects, citing complexity as a major hindrance to success. The book also discusses the impact of the digital revolution, using the example of a global IT outage caused by a faulty software update.
Project management methodologies are explored, tracing their origins from ancient civilisations to modern techniques such as CPM and PERT. The concept of cloud computing is examined, highlighting its benefits and potential security issues. The evolution and advantages of SaaS solutions are also discussed, noting their increased adoption during the COVID-19 pandemic.
The author then addresses supply chain challenges, using real-world examples to illustrate vulnerabilities. He traces the history of communication methods leading up to TCP/IP and discusses the development and importance of DNS. The differences between compliance and conformance in cybersecurity are clarified, emphasising that compliance does not equate to security.
Key cybersecurity standards such as the NIST CSF and ISO/IEC 27000 series are examined. The book also covers the Essential 8, a set of cybersecurity controls developed by the Australian Signals Directorate. The convergence of OT and IoT is discussed, highlighting the cybersecurity risks associated with this integration.
Emerging threats from AI and quantum computing are explored, noting their potential to both advance and threaten cybersecurity. The evolving legal landscape of cybersecurity is also covered, emphasising the need for international cooperation and innovative legal solutions.
In conclusion, the book stresses the importance of critical thinking and a holistic approach to cybersecurity, advocating for simplicity and foundational practices to enhance security.

Description:

This comprehensive volume presents a unified framework of continuum theories. It indicates that (i) microcontinuum theories (micromorphic and micropolar theories) are natural extension of classical continuum mechanics, and (ii) classical continuum mechanics is a special case of microcontinuum theories when the deformable material point is idealized as a single mathematical point. The kinematics and basic laws are rigorously derived. Based on axiomatic approach, constitutive theory is systematically derived for various kinds of materials, ranging from Stokesian fluid to thermo-visco-elastic-plastic solid. Material force and Thermomechanical-electromagnetic coupling are introduced and discussed. Moreover, general finite element methods for large-strain thermomechanical coupling physical phenomena are systematically formulated. Also, non-classical continuum theories (Nonlocal Theory, Mechanobiology, 4D printing, Poromechanics, and Non-Self-Similar Crack Propagation) are rigorously formulated with applications and demonstrated numerically.As an advanced monograph, this unique compendium can also be used as a textbook for several graduate courses, including continuum mechanics, finite element methods, and advanced engineering science theories. Extensive problems are provided to help students to better understand the topics covered.

Description:

Electromagnetic complex media are artificial materials that affect the propagation of electromagnetic waves in surprising ways not usually seen in nature. Because of their wide range of important applications, these materials have been intensely studied over the past twenty-five years, mainly from the perspectives of physics and engineering. But a body of rigorous mathematical theory has also gradually developed, and this is the first book to present that theory.

Designed for researchers and advanced graduate students in applied mathematics, electrical engineering, and physics, this book introduces the electromagnetics of complex media through a systematic, state-of-the-art account of their mathematical theory. The book combines the study of well posedness, homogenization, and controllability of Maxwell equations complemented with constitutive relations describing complex media. The book treats deterministic and stochastic problems both in the frequency and time domains. It also covers computational aspects and scattering problems, among other important topics. Detailed appendices make the book self-contained in terms of mathematical prerequisites, and accessible to engineers and physicists as well as mathematicians.
