In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...

We present one loop boundary reflection matrix for d (1) 4 Toda field theory defined on a half line with the Neumann boundary condition. This result demonstrates a nontrivial cancellation of non-meromorphic terms which are present when the model has a particle spectrum with more than one mass. Using this result, we determine uniquely the exact boundary reflection matrix which turns out to be ‘n...

We present the results of an experimental and numerical study of the distribution of the reflection coefficient P(R) and the distributions of the imaginary P(v) and the real P(u) parts of the Wigner reaction K matrix for irregular fully connected hexagon networks (graphs) in the presence of strong absorption. In the experiment we used microwave networks, which were built of coaxial cables and a...

Automated visual inspection of industrial textile printing has the potential to increase the overall print quality. In this article, we investigate whether all printed colors can be detected by CCD cameras and determine the color measurement precision.Occurring deviations in color values of homogenouesly colored textile patches are explained by the dichromatic reflection model. An extra clue is...

The slowly varying amplitude approximation that is widely adopted in nonlinear optics is appraised by the transfer-matrix method. Rigorous solution for second harmonic generation in nonlinear optical superlattices shows that this approximation is invalid when the reflection of the second harmonic ~SH! wave from the crystal interface cannot be neglected. When the modulation period of the superla...

In the present study, the inherent characteristic of carbon nanotubes to absorb/attenuate the energy of electromagnetic waves has been exploited. The results indicate that the incorporation of CNTs in the polyurethane matrix has significant effect on the microwave interaction properties. Fabrics are developed through coating process using formulations based on different concentrations of multi ...

We study the reflection of magnons from a D5-brane in the framework of the AdS/CFT correspondence. We consider two possible orientations of the D5-brane with respect to the reference vacuum state, namely vacuum states aligned along “vertical” and “horizontal” directions. We show that the reflections are of the achiral type. We also show that the reflection matrices satisfy the boundary Yang-Bax...
