microwave engineering and physical aspects of wireless communication In this book, the author addresses a wide range of radio-frequency and microwave topics with emphasis on physical aspects including EM and voltage waves, transmission lines, passive circuits, antennas, radio wave propagation. Up-to-date RF design tools like RF circuit simulation, EM simulation and computerized smith charts, are used in various examples to demonstrate how these methods can be applied effectively in RF engineering practice. Design rules and working examples illustrate the theoretical parts. The examples are close to real world problems, so the reader can directly transfer the methods within the context of their own work. At the end of each chapter a list of problems is given in order to deepen the reader's understanding of the chapter material and practice the new competences. Solutions are available on the author's website. Key Features: Presents a wide range of RF topics with emphasis on physical aspects e.g. EM and voltage waves, transmission lines, passive circuits, antennas Uses various examples of modern RF tools that show how the methods can be applied productively in RF engineering practice Incorporates various design examples using circuit and electromagnetic (EM) simulation software Discusses the propagation of waves: their representation, their effects, and their utilization in passive circuits and antenna structures Provides a list of problems at the end of each chapter Includes an accompanying website containing solutions to the problems (http:\\www.fh-dortmund.de\gustrau_rf_textbook) This will be an invaluable textbook for bachelor and masters students on electrical engineering courses (microwave engineering, basic circuit theory and electromagnetic fields, wirelesscommunications). Early-stage RF practitioners, engineers (e.g. application engineer) working in this area will also find this book of interest.Microwave circuitsRadio circuitsWireless communication systemsEquipment and suppliesMicrowave circuits.Radio circuits.Wireless communication systemsEquipment and supplies.621.382547.51njb/09621.382njb/09Gustrau Frank1785758MiAaPQMiAaPQMiAaPQBOOK9910975161703321RF and Microwave Engineering4317242UNINA04201nam 2200589Ia 450 991095635420332120251006184313.0978019535619901953561950-19-985345-21-4294-1560-61-280-52859-10-19-535619-5(MiAaPQ)EBC7034414(CKB)24235095300041(MiAaPQ)EBC271397(Au-PeEL)EBL271397(CaPaEBR)ebr10142253(CaONFJC)MIL52859(OCoLC)935260039(Au-PeEL)EBL7034414(OCoLC)1336402798(EXLCZ)992423509530004119960909d1997 uy 0engur|||||||||||txtrdacontentcrdamediacrrdacarrierEntangled voices genre and the religious construction of the self /Frederick J.

To this end, he joins literary theorists in the discussion about "narrative." Ruf rejects the idea of genre as a fixed historical form that serves as a template for readers and writers; instead, he suggests that we imagine different genres, whether narrative, lyric, or dramatic, as the expression of different voices. Each voice, he asserts, possesses different key qualities: embodiment, sociality, contextuality, and opacity in the dramatic voice; intimacy, limitation, urgency in lyric; and a "magisterial" quality of comprehensiveness and cohesiveness in narrative. These voices are models for our selves, composing an unruly and unstable multiplicity of selves. Ruf applies his theory of "voice" and "genre" to five texts: Dineson's Out of Africa, Donne's Holy Sonnets, Primo Levi's The Periodic Table, Robert Wilson's Einstein on the Beach, and Coleridge's Biographia Literaria. Through these literary works, he discerns the detailed ways in which a text constructs a voice and, in the process, a self. More importantly, Ruf demonstrates that this process is a religious one, fulfilling the function that religions traditionally assume: that of defining the self and its world.Religious literature, EnglishHistory and criticismTheory, etcSelf in literatureLiterary formReligious literature, EnglishHistory and criticismTheory, etc.Self in literature.Literary form.820.9/382Ruf Frederick J.1950-1850780MiAaPQMiAaPQMiAaPQBOOK9910956354203321Entangled voices4443976UNINA
