Marston views, and narratives of the Chinese mobile subjects in three ASEAN countries: Malaysia, Singapore and Thailand, and their interactions with the ethnic Chinese communities in these countries. This book is based on recent and updated original ethnographic research carried out by leading scholars in

Edwin L. Carstensen,David R. Bacon of China (PRC) Chinese in Bangkok. Conceptually, this paper remedies China-centricity, static migratory paradigm, “friend-foe” dichotomy trap, and single nation-state’s interests that are dominating existing studies. Bangkok is a conducive site as it is the capital of Thailand, one of the highest r

,History of Nonlinear Acoustics: 1750s–1930s,Fubini, Hugoniot, Lagrange, Langevin, Laplace, Poisson, Rankine, Rayleigh, Riemann, Stokes, and Taylor. This era produced the exact implicit Poisson and Riemann solutions for progressive and counterpropagating plane waves in an ideal fluid, respectively, Earnshaw’s extension of Poisson’s solution th

Dispersion,ween harmonics. Two examples of weak dispersion are considered, one due to relaxation, for which an analytical solution for a step shock is available, and another due to thermoviscous boundary layers in ducts. Strong dispersion is considered for propagation of sound in nonplanar waveguide modes, wit

Acoustic Streaming, by time-averaging the momentum equation with shear and bulk viscosity included. A volume integral for streaming in a free field produced by an arbitrary sound field is used to obtain a solution for streaming generated by a focused sound beam. Streaming produced by the viscous boundary layer acting

Sound Beams, second harmonic, sum, and difference frequencies in weakly nonlinear axisymmetric sound beams. Analytical solutions are obtained for sources with Gaussian amplitude distributions, both unfocused and focused. Asymptotic solutions are presented for far-field radiation from circular pistons, and the a
