Magnetic X-ray Reflectivity
… systems via magnetic soft and hard x-ray reflectivity. The focus here is on 3d transition metals, which are used mainly for development of numerous noval magnetic devices, that are both technologically and scientifically interesting. Complementary to Neutron diffraction, which is the …

Spatial effects and experience through reflectivity
… an exploration of a specific material property, reflectivity, and the effects it has on architecture in terms of experiencing a space and defining a space and redefining perceptions of one's self within space. Architectural projects often draw from materials and their specific properties to …

Reservoir characterization using seismic reflectivity and attributes
… this a two-step procedure is followed. First, reflectivity and acoustic impedance profiles are obtained from the inversion of post-stack seismic data. Second, a multi-attribute analysis, calibrated using well logs, is used to obtain porosity. This procedure is applied to a 40x40 sq. km field …

Computational 3D and reflectivity imaging with high photon efficiency
Imaging the 3D structure and reflectivity of a scene can be done using photon-counting detectors. Traditional imagers of this type typically require hundreds of detected photons per pixel for accurate 3D and reflectivity imaging. Under low light-level conditions, in which the mean photon count is …

Bidirectional Reflectance Measurements of Low-Reflectivity Optical Coating Z302
Black coatings essentially absorb incident light at all wavelengths from all directions. They are used when minimal reflection or maximum absorption is desired and therefore are effective in applications that require control of stray light. Our motivation stems from the use of black coating Lord …

An Investigation of Seismic Reflectivity Spectra, Moments, and Fractal Dimensions
Statistical models for seismic reflectivity spectra provide means of generating numerical reflection sequences as a priori information for seismic inversion, to test geophysical data processing techniques, and to parameterize real reflection sequences for classification purposes. I tested the …

Light-induced structural transition and reflectivity of a silica-gallium interface
… to melt phase transition. Transient pump-probe reflectivity measurements revealed the dynamics of a silica-gallium interface reflectivity change in the visible part of the spectrum for the first time. Reflectivity rise times of a few ps were observed and the accumulative nature of the …

Two-dimensional reflectivity polarization elastometry imaging techniques (PIET) of soft tissue
… described. The technique utilizes changes in the reflectivity of polarized light intensity as a monitor of skin stretch. Measurements on in-vitro pigskin and invivo human skin show that the reflectivity of polarized light intensity increases linearly with stretch over a range. The changes in …

All done by mirrors: reflectivity in the novels of Elizabeth Taylor (1912-75)
… high degree of referentiality. Seven kinds of "reflectivity" are proposed, with special attention to self-reflectivity - "reflexivity." The presence of "structural reflexivity" is shown in the first novel.Part 2 discusses the other 11 novels and one novella in pairs linked by the texts which …
