This book presents a novel methodology for the computation of RCS of metallic structures using a parallelized version of NEC in conjunction with a finite element preprocessor which has been strategically incorporated for simplifying geometry modelling catering to NEC guidelines. It includes a thorough overview of the theoretical background of NEC including all relevant aspects of formulation and modelling. The revised methodology including all the required steps and details is discussed elaborately along with case studies and validations. This book will serve as a valuable resource for students, researchers, scientists, and engineers working in the field of RCS predictions and measurements.
This book covers a variety of topics in Electronics and Communication Engineering, especially in the area of microelectronics and VLSI design, communication systems and networks, and signal and image processing. The content is based on papers presented at the 5th International Conference on VLSI, Communication and Signal Processing (VCAS 2022). The book also discusses the emerging applications of novel tools and techniques in image, video, and multimedia signal processing. This book is useful to students, researchers, and professionals working in the electronics and communication domain.
Stealth technology is a crucial pre-requisite in the combat zone, where swiftness, surprise and initiative are the decisive elements for survivability. The supreme goal here is to reduce the visibility of military vehicles by shaping, application of radar absorbing materials, passive cancellation, active cancellation etc. With respect to multilayered radar absorbing structures (RAS), this book presents an efficient algorithm based on particle swarm optimization (PSO), for the material selection as well as optimization of thickness of multilayered RAS models considering both normal as well as oblique incidence cases. It includes a thorough overview of the theoretical background required for t...
The design and development of low radar cross section (RCS) phased array has been a challenging subject in stealth technology. The frequency selective surface elements act as absorbers in specific frequency band and facilitate gain enhancement and reduction of antenna RCS. This book presents a comprehensive EM design and analysis of such low-profile patch arrays with high impedance surface-based ground plane. It explains how to determine radiation mode RCS of low-profile antenna arrays with arbitrary configurations. Detailed descriptions of design, workflow of determining radiation and scattering behavior of antenna arrays have been supported with schematics, tables, and illustrations. Aimed...
This handbook provides comprehensive and up-to-date information on the topic of scientific, industrial and legal metrology. It discusses the state-of-art review of various metrological aspects pertaining to redefinition of SI Units and their implications, applications of time and frequency metrology, certified reference materials, industrial metrology, industry 4.0, metrology in additive manufacturing, digital transformations in metrology, soft metrology and cyber security, optics in metrology, nano-metrology, metrology for advanced communication, environmental metrology, metrology in biomedical engineering, legal metrology and global trade, ionizing radiation metrology, advanced techniqu...
What makes a priest of one religion become a preacher of another religion? How could a person embrace a religion suddenly that he or she had up to then opposed? Why would young women risk their reputation and endanger their lives for the sake of newfound faith? How could an alcoholic detest a sip of wine all of a sudden? What drives an atheist to become an ardent worshiper of God? How could an intelligent person relate to God as to an adult human being? Transformative Religious Experience answers these questions with fascinating narratives of conversion. These narratives together show how the transforming effects of conversion permeate the daily lives of converts in a multireligious context....
Within a book, wisdom enshrined, Ramayana's tales unwind. Each poet's verse, a vibrant hue, Reflects Rama's journey, brave and true.
Ms. Vineeta Nair called 000(the Australian helpline) to inform the police that her husband died out of heart attack while sleeping. She woke up in morning and tried to wake her husband Mr. Sandy Nair up. But Sandy did not wake up. She then checked whether her husband was breathing, the result was negative. Vineeta was wailing loudly. She was repeatedly saying, “Who will take care of my son now, my husband died in heart attack.” Police came to inspect the “possible crime scene”. There was no sign of struggle, Mr. Sandy’s dead body was lying on the family bed peacefully, as if he was sleeping deeply. By seeing police, Ms. Vineeta started crying loudly, “My husband died at such a young age. With whom will I stay now? Who will take care of me? I cannot live without my husband. I want to die now.” One policewoman put her hand on Vineeta’s shoulder and asked her to keep calm. Mr. Sandy was lying dead in his pyjama, there was foaming at his mouth. Police enquired Vineeta about that. Vineeta said, “My husband drunk lot of whiskey last night, he did not listen to me. The foam may be coming out due to overconsumption of whiskey.”
Sukumaara Natana Thathwa, began with random thoughts, observations, reactions, being noted down for me alone, and then, very soon, it took on an existence of its own, dragging me along with it, tightly chained, so that I was pulled back to the subject in spite of the numerous deviations, where I was forced to play various roles, that of a wife, a mother, a teacher, even a performer! In every role I played, I felt insufficient, incomplete, except a few 'moments on stage, that stands out as the sole meaningful events that justify one's existence. It is perhaps these shining moments that has convinced me of the worth of this work. It is also the continuous, eternal search for these same moments, where life is transformed and all conflicts are momentarily resolved, when all seems well and alright in this world, that has led me on, into stage experiments with contents, as well as, stylistics of Mohiniattom, involving in-depth interpretations of characters represented on stage, attempting amalgamations of themes, combining fictions with ancient lore, also trying to bring universal relevance in thematic presentations.
In a time of increasing disconnection and uncertainty, Leading with Joy shows how leaders can reclaim their purpose and embrace joy in service of social transformation. Leadership that connects people and centers compassion and trust instead of competition and disconnection is needed more than ever before. There are plenty of manuals that show people how to manage organizations, but what is really needed in this moment is a book that shows us how to include kindness and inspiration within leadership. Leading with Joy promotes a courageous and compassionate approach to leadership that can sustain purposeful action and social change. This book takes the form of a series of vignettes about the ...
