Metaheuristics for Structural Design and Analysis discusses general properties and types of metaheuristic techniques, basic principles of topology, shape and size optimization of structures, and applications of metaheuristic algorithms in solving structural design problems. Analysis of structures using metaheuristic algorithms is also discussed. Comparisons are made with classical methods and modern computational methods through metaheuristic algorithms. In the development of metaheuristic algorithms, the use of biological evolution mechanisms, such as reproduction, mutation, recombination and selection is the most well-known technique, and these algorithms are grouped as evolutionary algorithms. In this class, the most popular and oldest algorithms are genetic algorithms.

Advanced technologies such as Artificial Intelligence (AI), Big Data, Cloud Computing, and Internet-of-Things (IoT) have changed the digital landscape, providing many new and exciting opportunities. However, they also provide ever-shifting gateways for information theft or misuse. Staying ahead requires the development of innovative and responsive security measures, and recent advances in optical technology have positioned it as a promising alternative to digital cryptography. Optical Cryptosystems introduces the subject of optical cryptography and provides up-to-date coverage of optical security schemes. Optical principles, approaches, and algorithms are discussed as well as applications, including image/data encryption-decryption, watermarking, image/data hiding, and authentication verification. This book also includes MATLAB codes, enabling students and research professionals to carry out exercises and develop newer methods of image/data security and authentication.

The use of ultrafast lasers has expanded beyond use by specialist laser physicists and is increasingly commonplace in both physical and life sciences, where the high intensities, broad bandwidths, and short pulse durations make them ideal for investigating a wide range of chemical and physical phenomena. Working with these ultrashort femtosecond laser pulses requires some special care when compared to other laser systems, and this book provides an ideal starting point for the non-specialist to gain the necessary knowledge to start effectively working with ultrafast lasers and optics. The book walks the reader through the relevant parts of ultrashort pulse physics, pulse generation, and pulse characterisation, before discussing how to practically build an optical setup and manipulate these pulses. Many aspects of the practicalities of working with optics and lasers that are often considered assumed knowledge by experienced campaigners are discussed in detail. Aimed specifically at non-specialists, the emphasis is placed on intuitive, qualitative understanding of the concepts.

This book covers the optical and electrical properties of nanoscale materials with an emphasis on how new and unique material properties result from the special nature of their electronic band structure. Beginning with a review of the optical and solid state physics needed for understanding optical and electrical properties, the book then introduces the electronic band structure of solids and discusses the effect of spin orbit coupling on the valence band, which is critical for understanding the optical properties of most nanoscale materials. Excitonic effects and excitons are also presented along with their effect on optical absorption. 2D materials, such as graphene and transition metal dichalcogenides, are host to unique electrical properties resulting from the electronic band structure. This book devotes significant attention to the optical and electrical properties of 2D and topological materials with an emphasis on optical measurements, electrical characterization of carrier transport, and a discussion of the electronic band structures using a tight binding approach.

Magneto-optics (MO) is a wide field in physics and describes, in general, any interaction between electromagnetic radiation and a material which is magnetized. The book gives a concise but comprehensive introduction to theory, calculus, and typical experimental set-up used in magneto-optics. It includes a variety of practice problems with detailed solutions. The focus lies on the spectral range between near-infrared and near ultraviolet light because it is easily accessible in experiment using standard quartz optics.
