the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

Although the emphasis in underwater acoustics for the last few decades has been in low-frequency acoustics, motivated by long range detection of submarines, there has been a continuing use of high-frequency acoustics in traditional specialized applications such as bottom mapping, mine hunting, torpedo homing and under ice navigation. The attractive characteristics of high-frequency sonar, high ...

This paper examines the degrees of correlation among vocal-tract and facial movement data and the speech acoustics. Multilinear techniques are applied to support the claims that facial motion during speech is largely a byproduct of producing the speech acoustics and further that the spectral envelope of the speech acoustics can be better estimated by the 3D motion of the face than by the midsag...

An experimental study was conducted to investigate the physics underlying the oscillation cycle of high Mach number, turbulent, open cavity flows. The specific aim was to investigate how the interaction between the cavity acoustics and the shear layer dynamics is affected by increasing Mach number. In the experiments the free-stream Mach numbers tested were 2 and 5, the cavity length-to-depth r...

microwave energy has potential for the efficient heating of minerals. minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. the mineral ilmenite is one which shows good dielectric heating characteristics. in this paper, the effect of microwave heat energy on the partial reduction of oxidized ilmenite oxidized in ...

This paper presents a proposal of an efficient binaural room-acoustics auralization method, essential goal modeling. The method uses massively parallel wave-based solver based on dispersion-optimized explicit time-domain finite element (TD-FEM). hybrid technique first-order Ambisonics (FOA) and head-related transfer functions. encoding room impulse responses computed by that can model sound abs...

The synthesis of single-cycle, compressed optical and microwave pulses sparked novel areas fundamental research. In the field acoustics, however, such a generation has not been introduced yet. For numerous applications, large spatial extent surface acoustic waves (SAW) causes unwanted perturbations limits accuracy physical manipulations. Particularly, this restriction applies to SAW-driven quan...
