Electromagnetics and Transmission Lines Textbook resource covering static electric and magnetic fields, dynamic electromagnetic fields, transmission lines, antennas, and signal integrity within a single course Electromagnetics and Transmission Lines provides coverage of what every electrical engineer (not just the electromagnetic specialist) should know about electromagnetic fields and transmission lines. This work examines several fundamental electrical engineering concepts and components from an electromagnetic fields viewpoint, such as electric circuit laws, resistance, capacitance, and self and mutual inductances. The approach to transmission lines (T-lines), Smith charts, and scattering parameters establishes the underlying concepts of vector network analyzer (VNA) measurements. System-level antenna parameters, basic wireless links, and signal integrity are examined in the final chapters. As an efficient learning resource, electromagnetics and transmission lines content is strategically modulated in breadth and depth towards a single semester objective. Extraneous, distracting topics are excluded. The wording style is somewhat more conversational than most electromagnetics textbooks in order to enhance student engagement and inclusivity while conveying the rigor that is essential for engineering student development. To aid in information retention, the authors also provide supplementary material, including a homework solutions manual, lecture notes, and VNA experiments. Sample topics covered in Electromagnetics and Transmission Lines include: Vector algebra and coordinate systems, Coulomb’s law, Biot-Savart law, Gauss’s law, and solenoidal magnetic flux Electric potential, Ampere’s circuital law, Faraday’s law, displacement current, and the electromagnetic principles underlying resistance, capacitance, and self and mutual inductances The integral form of Maxwell’s equations from a conceptual viewpoint that relates the equations to physical understanding (the differential forms are also included in an appendix) DC transients and AC steady-state waves, reflections, and standing waves on T-lines Interrelationships of AC steady-state T-line theory, the Smith chart, and scattering parameters Antenna basics and line-of-sight link analysis using the Friis equation An introduction to signal integrity Electromagnetics and Transmission Lines is an authoritative textbook learning resource, suited perfectly for engineering programs at colleges and universities with a single required electromagnetic fields course. Student background assumptions are multivariable calculus, DC and AC electric circuits, physics of electromagnetics, and elementary differential equations.
The relationship between class and intimate violence against women is much misunderstood. While many studies of intimate violence focus on poor and working-class women, few examine the issue comparatively in terms of class privilege and class disadvantage. James Ptacek draws on in-depth interviews with sixty women from wealthy, professional, working-class, and poor communities to investigate how social class shapes both women's experiences of violence and the responses of their communities to this violence. Ptacek's framing of women's victimization as "social entrapment" links private violence to public responses and connects social inequalities to the dilemmas that women face.
The author critiques the American obsession with imprisonment as punishment, calling it "retributive degradation" of the incarcerated. His analysis draws on both salient empirical data and material from a variety of disciplines - social history, anthropology, law and penal theory, philosophy of religion - as he uncovers the devastating social consequences (both direct and collateral) of imprisonment on such a large, unprecedented scale. The book develops a Christian social ethics of "good punishment" embodied as a politics of "healing memories" and "ontological intimacy
This writing spiritually, passionately, and intellectually addresses the issues surrounding the silence of both church and secular community concerning violence against women. The author shares a model of ministry that engaged women who courageously describe their victimization, bringing the reader into the heart of their woundedness. This ministry model has proven effective in breaking the silence of abuse while providing a safe, nurturing environment in which victims of abuse may begin the lengthy process of healing. This book is a must-read for women and men alike, as we are all somehow associated with a female victim-survivor of violence and abuse.
This book offers a comprehensive introduction to juvenile delinquency by defining and describing juvenile delinquency, examining explanations for delinquent behavior, and considering contemporary efforts to control delinquency through prevention and juvenile justice. The text cultivates an understanding of juvenile delinquency by examining and linking key criminological theories and research. Coverage includes: the historical origins and transformation of "juvenile delinquency" and juvenile justice; the nature of delinquency, addressing the extent of delinquent offenses, the social correlates of offending and victimization (age, gender, race and ethnicity, and social class), and the developmental patterns of offending; theoretical explanations of delinquency, with insights from biosocial criminology, routine activities, rational choice, social control, social learning, social structure, labeling, and critical criminologies; evidence-based practice in delinquency prevention and contemporary juvenile justice. Fully revised and updated, the new edition incorporates the latest theory and research in the field of juvenile delinquency and provides expanded discussion of contemporary juvenile justice reform, evidence-based practice in delinquency prevention, and disproportionate minority contact throughout the juvenile justice process. This book is essential reading for courses on juvenile delinquency and juvenile justice. The book is supported by a range of compelling pedagogical features. Each chapter includes key terms, learning objectives, an opening case study, box inserts that provide practical application of theory and research, critical thinking questions, suggested reading, useful websites, and a glossary of key terms. A companion website offers an array of resources for students and instructors. For students, this website provides chapter overviews, flashcards of key terms, and useful websites. The instructor site is password protected and offers a complete set of PowerPoint slides and an extensive test bank for each chapter—all prepared by the authors.
