In recent years, holographic optical elements have been introduced in different applications such as high-density data storage, interconnections, spatial and temporal filters and three-dimensional displays. Simultaneously, more sensitive, efficient and durable holographic materials have been developed. Thus it is necessary…

A statistical model is used to study the formation of noise gratings in holograms and the mechanism that causes radiation scattering in them. The theoretical model presented describes noise scattering in terms of diffraction due to the high number of…

A more accurate analytical approximate expression for the slope at any point of the elastic curve of a slender cantilever column is obtained by using a heuristic but pedagogical derivation. This derivation is based on the linearization of the nonlinear…

In this paper, a cooperative robot-robot approach to construct metallic structures is presented. In order to develop this task, a visual-force control system is proposed. The visual information is composed of an eye-in-hand camera, and a time of flight 3D…

This paper briefly introduces a summary of the special session on Hybrid Reasoning and Coordination Methods on Multi-Agent Systems, held in conjunction with the 4th International Conference on Hybrid Artificial Intelligence Systems 2009 (HAIS’09). The research papers of this session…

Objective: This exploratory, clinical study aimed to explore the effect of an activated charcoal silver dressing (intervention) with cleansing and debridement (control) in reducing the level of bacteria in chronic wounds with no clinical signs of local infection. Method: Patients…

The effect of bulk and surface excitations to inelastic scattering in low-energy electron beam irradiation of multi-walled carbon nanotubes (MWNTs) is studied using the dielectric formalism. Calculations are based on a semiempirical dielectric response function for MWCNTs determined by means…

An analytical approximate technique for conservative nonlinear oscillators is proposed. This method is a modification of the generalized harmonic balance method in which analytical approximate solutions have rational form. This approach gives us not only a truly periodic solution but…

One of the issues attracting wider attention within the research into corporate internationalization is the choice of mode of entry into a foreign country. At present, China is one of the destinations which is acquiring greater importance in the international…

In this paper, we propose an original method to geoposition an audio/video stream with multiple emitters that are at the same time receivers of the mixed signal. The obtained method is suitable when a list of positions within a known…
