Electromagnetic Optimization by Genetic Algorithms by Yahya Rahmat-Samii, ISBN 0471295450
Authoritative coverage of a revolutionary technique for overcoming problems in electromagnetic design Genetic algorithms are stochastic search procedures modeled on the Darwinian concepts of natural selection and evolution. The machinery of genetic algorithms utilizes an optimization methodology that allows a global search of the cost surface via statistical random processes dictated by the Darwinian evolutionary concept. These easily programmed and readily implemented procedures robustly locate extrema of highly multimodal functions and therefore are particularly well suited to finding solutions to a broad range of electromagnetic optimization problems. Electromagnetic Optimization by Genetic Algorithms is the first book devoted exclusively to the application of genetic algorithms to electromagnetic device design. Compiled by two highly competent and well-respected members of the electromagnetics community, this book describes numerous applications of genetic algorithms to the design and optimization of various low- and high-frequency electromagnetic components. Special features include: Introduction by David E. Goldberg, " A Meditation on the Application of Genetic Algorithms" Design of linear and planar arrays using genetic algorithmsApplication of genetic algorithms to the design of broadband, wire, and integrated antennasGenetic algorithm— driven design of dielectric gratings and frequency-selective surfacesSynthesis of magnetostatic devices using genetic algorithmsApplication of genetic algorithms to multiobjective electromagnetic backscattering optimizationA comprehensive list of the up-to-date references applicable to electromagnetic design problemsSupplementedwith more than 250 illustrations, Electromagnetic Optimization by Genetic Algorithms is a powerful resource for electrical engineers interested in modern electromagnetic designs and an indispensable reference for university researchers.
Intuitive Wellness: Using Your Body's Inner Wisdom to Heal
Twenty years ago, Laura Alden Kamm recovered from a near-death experience with the amazing new ability to telepathically scan the structure of a person's body and see inner disturbances in intricate detail. Kamm also had the ability to see Kirlian fields -- the electromagnetic energies that pulse around all organic matter. She has since created educational programs to train others in the intuitive way to prevent or reverse disease.
Kamm shows us how to become our own healers by both preventing disease before it manifests physically and treating existing conditions. Clearly explaining both ancient and newly developing philosophies that guide her work, she offers quick, simple, and practical exercises that help readers learn about their unique energy systems, develop confidence in their intuition, and resolve emotional and physical pain.

Earthquake Thermodynamics and Phase Transformation in the Earth's Interior by Roman Teisseyre, ISBN 0126851859
A group of distinguished scientists contributes to the foundations of a new discipline in Earth sciences: earthquake thermodynamics and thermodynamics of formation of the Earth's interior structures. The predictive powers of thermodynamics are so great that those aspiring to model earthquake and the Earth's interior will certainly wish to be able to use the theory. Thermodynamics is our only method of understanding and predicting the behavior of many environmental, atmospheric, and geological processes. The need for Earth scientists to develop a functional knowledge of thermodynamic concepts and methodology is therefore urgent. Sources of an entropy increase the dissipative and self-organizing systems driving the evolution and dynamics of the Universe and Earth through irreversible processes. The non-linear interactions lead to the formation of fractal structures. From the structural phase transformations the important interior boundaries emerge.
Non-linear interactions between the...
