Kim starts with vibrations and waves, demonstrating how vibration can be envisaged as a kind of wave, mathematically and physically. One-dimensional waves are used to convey the fundamental concepts. Readers can then understand wave propagation in terms of characteristic and driving point impedance. The essential measures for acoustic waves, such as dB scale, octave scale, acoustic pressure, energy, and intensity, are explained. These measures are all realized by one-dimensional examples, which provide mathematically simplest but clear enough physical insights. Kim then moves on to explaining waves on a flat surface of discontinuity, demonstrating how propagation characteristics of waves change in space when there is a distributed impedance mismatch. Next is a chapter on radiation, scattering, and diffraction, where Kim shows how these topics can be explained in a unified way, by seeing the changes of waves due to spatially distributed impedance. Lastly, Kim covers sound in closed space, which is considered to be a space that is surrounded by spatially distributed impedance, and introduces two spaces: acoustically large and small space. The bulk of the book is concerned with introducing core fundamental concepts, but the appendices are included as the essentials as well to cover other important topics to extend learning. Offers a less mathematically-intensive means to understand the subject matter; Provides an excellent launching point for more advanced study or for review of the basics; Based on classroom tested materials developed over the course of two decades; Companion site for readers, containing animations and MATLAB code downloads; Videos and impedance data available from the author's website; Presentation slides available for instructor use Sound Propagation is geared towards graduate students and advanced undergraduates in acoustics, audio engineering, and noise control engineering. Practicing engineers and researchers in audio engineering and noise control, or students in engineering and physics disciplines, who want to gain an understanding of sound and vibration concepts, will also find the book to be a helpful resource.Acoustic impedanceSoundTransmissionSound-wavesAcoustic impedance.SoundTransmission.Sound-waves.534Kim Yang-Hann619880MiAaPQMiAaPQMiAaPQBOOK9910811611803321Sound propagation4031759UNINA04529nam 22012375 450 991013616060332120250416110525.0(CKB)3780000000048953(MH)014196219-4(SSID)ssj0001568459(PQKBManifestationID)16214590(PQKBTitleCode)TC0001568459(PQKBWorkID)14813302(PQKB)11558929(PPN)193420732(FR-PaCSA)88842253(FRCYB88842253)88842253(EXLCZ)99378000000004895320140513d2014 my bfreurun| |||||txtccrEthique, droit et maladie d'AlzheimerParis Academia20141 online resource (88 p.)Intellection âEthique, droit et maladie d'Alzheimer Anne Meyer-HeineL'ouvrage consiste à aborder les questions éthiques, juridiques et de gouvernance politique impliquées dans la prise en charge des patients atteints de la maladie d'Alzheimer.

Conclusion.This book examines US President Barack Obama’s characterizations in the Brazilian media, with a specific focus on political cartoons and internet memes. Brazilians celebrate their country as a racial democracy; thus the US works as its nemesis. The rise of a black president to the office of the most prominent country in the global, political, and economic landscape led some analysts to postulate that the US was living in a post-racial era. President Obama’s election also had a tremendous impact on the imaginary of the African Diaspora, and this volume investigates how the election of the first black US president complicates Brazilians’ own racial discourses. By focusing on three events—Barack Obama's election in 2008, his visit to Brazil in March 2011, and the aftermath of the US espionage on the Brazilian government in 2013—Emanuelle Oliveira-Monte analyzes Barack Obama's shifting portrayals that confirm and challenge Brazilian racial conceptions projected upon his figure.EthnologyLatin AmericaCultureRaceAmericaPolitics and governmentCommunicationLatin American CultureRace and Ethnicity StudiesAmerican PoliticsGlobal and International CultureMedia and CommunicationEthnologyCulture.Race.AmericaPolitics and government.Communication.Latin American Culture.Race and Ethnicity Studies.American Politics.Global and International Culture.Media and Communication.306.098Oliveira-Monte Emanuelle K.
