Saltation of particles in turbulent channel flow
The role of focal block (trough/plane) in panoramic radiography: Why do some structures appear blurred out on these images?
(Elsevier/Science Direct, 2014-05-01)
Panoramic radiographs are commonly used in dental practice. The challenge with panoramic radiography is overlapping structures, ghost and air shadows. The area of interest can appear blurred especially in the anterior ...
Sound Scattering and Its Reduction by a Janus Sphere Type
Sound scattering by a Janus sphere type is considered. The sphere has two surface zones: a soft surface of zero acoustic impedance and a hard surface of infinite acoustic impedance. The zones are arranged such that axisymmetry ...
Piezoelectric nanogenerators - a review of nanostructured piezoelectric energy harvesters
© 2014 Elsevier Ltd. A huge number of piezoelectric materials have been demonstrated since the discovery of piezoelectricity over a century ago. The use of nanostructured piezoelectrics, however, is a relatively recent ...
