We study the thermoelastic deformation of an elastic layer. The upper surface of the medium is subjected to a uniform thermal field along a circular area while the layer is resting on a rigid smooth circular base. The doubly mixed boundary value problem is reduced to a pair of systems of dual integral equations. The both system of the heat conduction and the mechanical problems are calculated b...

We present an algorithm of matching 3D volumetric functions based on affine-invariant multi-resolution dual contour trees. A dual contour tree structure is constructed from the contour tree of a volume by dividing its functional range into segments such that the connected contour tree edges within a segment become a node in the dual tree. Each node of the dual contour tree corresponds to a conn...

introduction: transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. in this study, we compared and evaluated the treatment effects of dual frequency irradiatio...

Precise measurements on the density of sodium polystyrenesulphonate solutions in methanol-water mixed solvent media containing 8, 16, and 25 weight per cent of methanol at 308.15, 318.15, and 323.15 K are reported. The degree of substitution of sodium polystyrenesulphonate used is 1, and the concentrations are varied from 1 ×10 to 3.8 ×10 monomol.l. The results showed a slight increase on the p...

A novel channel-switch-mode strategy for simultaneous sensing of Fe(3+) and Hg(2+) is developed with dual-excitation single-emission graphene quantum dots (GQDs). By utilizing the dual-channel fluorescence response performance of GQDs, this strategy achieved a facile, low-cost, masking agent-free, quantitative and selective dual-ion assay even in mixed ion samples and practical water samples.

Volume data are usually represented as a uniform structured grid. Nevertheless, this representation imposes large memory requirements when large volumes are stored. Hierarchical representations, can be used to reduce either memory requirements or rendering time. Their use to store the volume model make the surface extraction process more complex, as cracks may appear on the boundary of cells wi...
