Statistical Investigation of Friction Stir Processing Parameter Relationships
… is still inadequate. Knowledge of FSW parameter relationships is needed to better understand the process and implement proper machine control. This study utilized a 3-factor, 3-level factorial design of experiments to investigate relationships between key process inputs and measured …

Evaluation of iron valence state alterations in thermally processed liquid model systems
… iron were measured for the model systems at each processing parameter. Data from the iron profiles were evaluated for the effect of iron salt; ascorbic acid; glucose and glycine, and processing temperature and time on changes in the iron chemistry during processing. The ferrous sulfate model …

Multi-photon decay mode spectroscopy of positronium
… an optimal selection of the digital signal processing parameter settings. The detectors were situated in a planar geometry, where the source-to-detector distance of the detector system was selected such that the effect of peak pulse pile-up was minimised (to less than 3%), while maximising …

Umladen von Fremdionen beim Modifizieren von Glas mit UV-Laserstrahlung für das Farbmarkieren und Strukturieren
… spectroscopy as a function of the laser parameter (e.g. wavelength, energy density and pulse duration), material parameter (e.g. concentration of ions) and processing parameter. Based on the measured changes of the absorption and concentration of polyvalent ions incorporated in the glass …

High-temperature defect engineering for silicon solar cells : predictive process simulation and synchrotron-based microcharacterization
… be solved in about 1 minute assuming standard processing conditions, allowing for rapid iteration. By wrapping the kinetics simulation tool with a genetic algorithm, global optima in the high-dimensional processing parameter space can be pursued for a given starting metal concentration and …

Characterization and modification of electrospun fiber mats for use in composite proton exchange membranes
… conditions alone. Changing a single fluid or processing parameter can affect the jet and fiber formation through several mechanisms. For example, using a different solvent can change several properties of the electrospinning fluid, such as the dielectric constant, conductivity, surface …

Global optimization methods for full-reference and no-reference motion estimation with applications to atherosclerotic plaque motion and strain imaging
… complexity with an increasing number of motion parameters. The standard approach of heuristically setting the motion parameters has become a major source of estimation error. This dissertation is focused in the development of reliable motion estimation based on global parameter optimization …

Identification of an Unsteady Aerodynamic Model up to High Angle of Attack Regime
… on the basis of multirate digital signal processing techniques. Since the model is sting-mounted to the support system of DyPPiR, the Discrete Fourier Transform (DFT) is first used to identify the frequencies of the elastic modes of sting. Then the sampling rate conversion systems are …
