Et il est vrai que, dans un monde de plus en plus soumis à la tyrannie des clivages, les multiples approches épistémologiques de sa recherche, ses prises de responsabilités institutionnelles et les transferts entre langues et cultures qui la fascinent prennent rétrospectivement des allures de rêve interdit. Pourtant, ce parcours ne devrait-il pas être celui, naturel, de tout enseignant chercheur en prise sur la complexité du monde ? Sur le mode de la chronique, cette biographie scientifique suit la constitution d?une méthode intellectuelle, s?enrichissant d?apports variés et des sollicitations de la vie. Elle prouve que la rigueur la plus exigeante ne tord pas forcément le cou à la fantaisie et qu?une certaine liberté d?esprit conduit aux chemins de traverse qui font progresser la recherche. Ce livre s?ouvre comme une histoire, celle d?une enfant confrontée à la diversité des langues et des cultures. Le récit prend ensuite des allures de roman d?apprentissage, celui d?un personnage qui, tout en accomplissant les exercices requis, continue de ressentir, à l?égard de certains aspects du jeu académique, une irréductible étrangeté. Un ton souvent teinté d?humour nous accompagne au travers d?anecdotes qui ont tissé la vie de grandes institutions. Un recueil de poèmes clôt le volume. Loin d?en être une annexe, il s?impose comme seul langage apte à en faire la synthèse : point d?asymptote entre lucidité et ingénuité assumée. 606 $aHistory 606 $ahistoire 606 $arécit personnel 606 $aégo-histoire 610 $ahistoire 610 $arécit personnel 610 $aégo-histoire 615 4$aHistory 615 4$ahistoire 615 4$arécit personnel 615 4$aégo-histoire 700 $aPagan$b Martine$01287566 801 0$bFR-FrMaCLE 906 $aBOOK 912 $a9910551849303321 996 $aLe corps du texte$93020187 997 $aUNINA LEADER 03800nam 22005295 450 001 9910571891703321 005 20231117154703.0 010 $a9781644698266 010 $a1644698269 024 7 $a10.1515/9781644698266 035 $a(CKB)5860000000049215 035 $a(DE-B1597)632884 035 $a(DE-B1597)9781644698266 035 $a(MiAaPQ)EBC6977609 035 $a(Au-PeEL)EBL6977609 035 $a(OCoLC)1334344722 035 $a(ScCtBLL)3d19c1f4-96e3-4a65-a91b-d4a4976c3029 035 $a(EXLCZ)995860000000049215 100 $a20220629h20222022 fg 101 0 $aeng 135 $aur||#|||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aPiezoelectric Electromechanical Transducers for Underwater Sound$hPart II$iSubsystems of the electroacoustic transducers /$fBoris S.

Special Functions 330 $aThe book presents a broad-scope analysis of piezoelectric electromechanical transducers and the related aspects of practical transducer design for underwater applications. It uses an energy method for analyzing transducer problems that provides the physical insight important for the understanding of electromechanical devices. Application of the method is first illustrated with transducer examples that can be modeled as systems with a single degree of freedom, (such as spheres, short cylinders, bars and flexural disks and plates made of piezoelectric ceramics). Thereupon, transducers are modeled as devices with multiple degrees of freedom. In all these cases, results of modeling are presented in the form of equivalent electromechanical circuits convenient for the calculation of the transducers? operational characteristics. Special focus is made on the effects of coupled vibrations in mechanical systems on transducer performance. The book also provides extensive coverage of acoustic radiation including acoustic interaction between the transducers. The book is inherently multidisciplinary. It provides essential background regarding the vibration of elastic passive and piezoelectric bodies, piezoelectricity, acoustic radiation, and transducer characterization. Scientists and engineers working in the field of electroacoustics and those involved in education in the field will find this material useful not only for underwater acoustics, but also for electromechanics, energy conversion and medical ultrasonics. Part II contains general information on vibration of mechanical systems, electromechanical conversion in the deformed piezoceramic bodies, and acoustic radiation that can be used independently for treatment transducers of different type. 606 $aPiezoelectric transducers 606 $aUnderwater acoustics 606 $aTechnology & Engineering / Acoustics & Sound$2bisacsh 615 0$aPiezoelectric transducers. 615 0$aUnderwater acoustics. 615 7$aTechnology & Engineering / Acoustics & Sound. 676 $a681.2 700 $aAronov$b B.
