Sommario/riassunto |
|
The first to address the solution of integral equations in both time and frequency domainsIntegral equations-based methods are among the |

|
|
|
|
|
most versatile techniques that one can use for the electromagnetic analysis of both conducting and piecewise homogeneous material bodies. They provide both efficient and accurate solutions for challenging problems, such as analysis of electrically large structures. Written by leading researchers in the field, Time and Frequency Domain Solutions of EM Problems Using Integral Equations and a Hybrid Methodology provides a compendium of solution techniques dealing with integral equations arising in electromagnetic field problems in the time and frequency domains.This book deals primarily with the novel solution of time domain integral equations. It documents the authors' unique space/time separation approach using associated Laguerre functions. A hybrid method based simultaneously on the time and frequency domains is presented to illustrate how to go beyond the limitations of the hardware resources of a computer to solve challenging electrically large electromagnetic field problems. User-friendly electromagnetic analysis computer codes are provided along with examples illustrating the various methodologies. The book also:. Provides a summary of the different types of spaces including the concept of mapping and projections leading to the formulation of operator equations. Discusses the solution of frequency domain integral equations using the popular triangular discretizations and the RWG basis functions. Describes how to solve time domain integral equations using the classic marching-on-in-time (MOT) and the new marching-on-in-degree (MOD) methodologies. Presents a new, improved version of the marching-on-in-degree (MOD) methodology. Presents a hybrid methodology by using early time and low frequency information to solve large problems no longer limited by the hardware resources of the computerWith sample computer programs and examples, this book is ideal for graduate students and scientists in electrical engineering and computational electromagnetics who are looking to gain a basic understanding of the numerical solution of integral equations in frequency and time domains. A unique text designed to increase understanding of the content through hands-on material, Time and Frequency Domain Solutions of EM Problems Using Integral Equations and a Hybrid Methodology is useful for both research and teaching. |

Sommario/riassunto |
|
"The bold challenge at the heart of this study is to renew our understanding of realist literature, not as stale, outdated, or even dead, but as witness to the "slow violence" of material and environmental dispossession and as bearer of radical, utopian energies. The three realist writers who are the focus of this study-Charles Dickens, George Eliot, and Thomas Hardy-each trace a series of figurations of the common in the wake of the physical or literal commons' destruction, endowing both the historical trauma that was enclosure and the utopian spirit that the commons embodied with an afterlife, one that reveals a radical politics at the heart of these most canonical writers' works"-- |

Sommario/riassunto |
|
During the Middle Ages, many occult rituals and beliefs existed and were practiced alongside those officially sanctioned by the church. While educated clergy condemned some of these as magic, many of these practices involved religious language, rituals, or objects. For instance, charms recited to cure illnesses invoked God and the saints, and love spells used consecrated substances such as the Eucharist. Magic and Religion in Medieval England explores the entanglement of magical practices and the clergy during the Middle Ages, uncovering how churchmen decided which of these practices |
