In this paper, we present a wavelet-based multigrid approach to solve the perturbation equation encountered in optical tomography. With this scheme, the unknown image, the data, as well as the weight matrix are all represented by wavelet expansions, thus yielding a multiresolution representation of the original perturbation equation in the wavelet domain.(More)

Acoustic manipulation has been widely studied and applied in many research and industry fields. Recently Surface Acoustic Wave (SAW) technology, because of its energy concentration and easy integration, has become more and more popular in microfluidics. In this paper, we fabricated our SAW chips and setup a SAW-based acoustic manipulation system. To study(More)
Air pollution caused by the indoor fine particulate matter cannot be ignored. To monitor the indoor air quality, a portable and uncomplicated separation and sampling device is required. Here, we present the design of fine particles separation and sampling system which is based on air-microfluidic technology. We use the color polystyrene microspheres with(More)

In this paper, the four integral identities satisfied by the fundamental solution for elasto-static problems are reviewed and slightly different forms of the third and fourth identities are presented. Two new identities, namely the fifth and sixth identities, are derived. These integral identities can be used to develop weakly singular and nonsingular forms(More)
