Long lengths (250 meters) of a flexible 150 microm diameter glass-clad optical fiber containing a 15 microm diameter crystalline and phase-pure germanium core was fabricated using conventional optical fiber draw techniques. X-ray diffraction and spontaneous Raman scattering measurements showed the core to be very highly crystalline germanium with no observed secondary phases. Elemental analysis...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Differentiation is ubiquitous in high energy physics, for instance in minimization algorithms and statistical analysis, in detector alignment and calibration, and in theory. Automatic differentiation (AD) avoids well-known limitations in round-offs and speed, which symbolic and numerical differentiation suffer from, by transforming the source code of functions. We will present how AD can be use...
The slurry erosion behaviour of laser clad Fe–Cr–B–Si alloy coatings was investigated at impact angles from 30u to 90u with an increment of 15u, and compared with the slurry erosion behaviour of two laser clad carbide coatings and a non-coated substrate made of AISI 4140 steel. The Fe–Cr–B–Si alloy coatings had slurry erosion resistance. Their overall slurry erosion resistance at impact angles ...
Practical considerations for choosing between Tobit, symmetrically censored least squares (SCLS) and censored least absolute deviations (CLAD) estimators are offered. Practical considerations deal with when a Hausman test is better than a conditional moment test for judging the severity of a misspecification, the need to bootstrap the sampling distributions of theHausman tests, what to look for...
The paper deals with the case of a three-layer liquid crystal tapered optical fiber (LCTOF) for which the dispersion relations are deduced corresponding to the TE and the TM modes. For the LCTOF under consideration, the outermost clad section is made of liquid crystal material with radial anisotropy whereas the core and the inner clad are homogeneous, non-magnetic and isotropic dielectric regio...
This paper presents an investigation on single objective optimization for CO2 laser cladding process considering clad height (H) and clad width (W) as performance characteristics. This optimization of multiple quality characteristics has been done using Genetic Algorithm (GA) approach. The aim of this work is to predict the performance characteristics (H and W) at optimized condition by applyin...
This paper describes a study carried out to investigate the capabilities of computer aided design software for the visualisation of building elevations and detail, with focus on the representation of photovoltaic cells in facade architecture. The development of photovoltaic (PV) technology, converting energy from sunlight into electricity, has resulted in the emergence of PV as a building mater...
Here we examine the waveguide dispersion property of slot waveguides, approaching/analyzing the given problem with respect to the normalized index contrast, Δnslot-core/ncore and Δncore-clad/ncore between adjacent layers . For two index contrasts of concern, it is found that their contributions to slot waveguide dispersions are substantially different, with Δnslot-core and Δncore-clad each acti...
A scalar variational analysis based on a Gaussian approximation of the fundamental mode of a double-clad elliptical fiber with a depressed inner cladding is studied. The polarization properties and graphic results are presented; they are given in terms of three parameters: the ratio of the major axis to the minor axis of the core, the ratio of the inner cladding major axis to the core major axi...
