Surface plasmon resonance (SPR) of nanostructured thin metal films (so-called nanoplasmonics) has attracted intense attention due to its versatility for optical sensing and chip-based device integration. Understanding the underlying physics and developing applications of nanoplasmonic devices with desirable optical properties, e.g. intensity of light scattering and high refractive index (RI) se...

This report presents a synoptic overview of Thue Systems. Thue Systems were introduced in the early 1900s by the Norwegian mathematician and logician Axel Thue. In this report the author suggests ways in which such systems can be used in pattern recognition.

The goal of data mining is to extract or mine" knowledge from large amounts of data. Emerging technologies of semi-structured data have attracted wide attention of networks, e-commerce, information retrieval and databases.XML has become very popular for representing semi structured data and a standard for data exchange over the web. Mining XML data from the web is becoming increasingly importan...

a semi-automatic 9-row transplanter for bare root seedlings has recently been developed at the isfahan center for agricultural research that plants 80 seedlings/m2 using 9 operators at a capacity of 0.3 ha/d (8 h). separating a single seedling from a bunch and dropping it into a distributer cell by hand takes 1 s on average. at a density of 700-800 thousand/ha, the travel speed should not excee...

This article presents a numerical model to study wave turbulence in fluids. The equation is derived by incorporating energy conservation (along with the usual fluid equations of compressible flow), and source nonlinearity rise temperature due acoustic wave's high amplitude. nonlinear Schrödinger (NLS) modified (MNLS) have been then solved numerically. A simulation MNLS used for investigating ge...

The Laser ultrasonic technique (LUT) is an interesting method to perform inspection of large aeronautical panels of complex shapes. Its non-contact feature avoids coupling problems and could improve the efficiency of the NDT inspection in the composite manufacturing industry. If the ultrasound generation process is well understood in metallic samples, the application of the technique in composi...
