Studies the evolution of polarization state an electromagnetic wave propagating in a non-homogeneous plasma with sheared magnetic field. A differential equation is given describing such case slowly varying parameters. Assuming model cold collisionless one obtains approximate solution giving output as function input and parameters along path. These results are applied to Tokamak; it shown that some particular cases relatively simple functional poloidal Therefore measurements can be used...
The integration of facility management and building information modelling (BIM) is an innovative critical undertaking process to support maintenance management. Even though recent research has proposed various methods performed increasing number case studies, there are still issues communication processes be addressed. This paper presents a theoretical framework for digital systems virtual models smart technologies. Based on the comprehensive analysis existing technologies indoor...
We report the preparation and characterization of novel isotropic polymer slab waveguides made by photochemical crosslinking, their integration with a ferroelectric liquid crystal in an integra ...
Abstract Two integrated electro-optic switches based on smectic C * ferroelectric liquid crystal (FLC) planar waveguides oriented in the bookshelf geometry have been designed and realized. In order to test first switch, a particular waveguide structure consisting of three-stage device, having thin FLC film middle stage two glass as other stages, has The second one is realized by with overlayer. this article design, realization, experimental characterization electro-optical are reported....

The early stage diagnoses of material lattices is becoming a crucial requirement where investigation methods and technologies are faced with both aging components materials. mixing effects wear, fatigue, temperature variation environment conditions translate into variations the atomic flux rate internal rearrangement grain size boundaries lattices. related lattice measurements (e.g. d-.spacing one important among others) become only usable for structural integrity. When such base to identify...
A mode matching telescope for an EPR squeezer was designed with confocal off-axis configuration. Coupling loss is calculated as 0.02%, and the fabrication expected to be feasible based on sensitivity analysis Monte-Carlo simulation.
Reproducibility of diffraction experiments provides an indication data consistency with respect to different variables. The level reproducibility and accuracy the measurements is increased when using calibrated instruments. paper presents most significant results 'Calibration Monitoring Diffractometers', a project systematic approach Round Robin tests. At present stage, suggest that instrumental performances other related experimental effects in experiment can be summarised through...
A guided light wave can be modulated by coupling it into a ferroelectric liquid crystal (FLC) waveguide. The FLC, which changes its optical properties under the application of an electric field, acts as active medium. With carefully chosen aligned configuration, large change in refractive index induced gives good contrast ratio response. and electro- crystals modified propagating these effects enhanced addition suitable absorbing dye crystal. Thus guiding conditions also itself.
X-ray and neutron diffractometric methods are described for the early-stage diagnosis of materials. A comparison is made between traditional innovative technologies, which aim at being included amongst NDT usable on-site. Emphasis also placed on gradual removal from instruments structural restraints, with a tendency towards anthropomorphic functionalities flexibility. Prototype production conceptual schemes presented discussed. Conceptual tests, applications case studies shown as per state...
The present paper is about the estimation of lattice deformation from data collected manufactures directly on site. aim here to give evidence that concept Mean Equivalent Lattice (MEL), when applied “on site X-Ray Diffraction” basis for a reliable qualification material rheology external solicitations. Such method allows identification deformations without resorting computation residual stress with using elasticity constants (i.e. tensile, shear and rigidity E , μ, ν); these descend...
