A novel beam position monitor, operated at zero bias voltage, based on high-quality chemical-vapor-deposition single-crystal Schottky diamond for use under intense synchrotron X-ray beams was fabricated and tested. The total thickness of the diamond thin-film beam monitor is about 60 µm. The diamond beam monitor was inserted in the B16 beamline of the Diamond Light Source synchrotron in Harwell...

Surface plasmon resonance (SPR) spectroscopy has been used to follow incorporation and light-induced conformational changes in bovine rhodopsin reconstituted into an egg phosphatidylcholine bilayer deposited on a thin silver film. The magnitude of the SPR spectral changes caused by light varies with pH in a manner paralleling that in flash photolysis experiments, which monitor formation of meta...

The topic of data warehousing encompasses architec-tures, algorithms, and tools for bringing together selected data from multiple databases or other information sources into a single repository, called a data warehouse , suitable for direct querying or analysis. In recent years data warehousing has become a prominent buz-zword in the database industry, but attention from the database research c...

Recently, we have developed a novel beam profile monitor based on a supersonic gas jet. It can be applied to some extreme situation while other methods are not applicable such as for the high intensity and energy beams with destructive power and for the short life beam which requires minimum interference. The resolution of this monitor depends on the jet thickness and homogeneity, and thus we d...

[1] To estimate sea ice thickness over a large spatial scale is a challenge. In this paper, we propose a direct approach to effectively estimate sea ice thickness over a large spatial area of the Bohai Sea using EOS MODIS data. It is based on the model of an exponential relation between albedo and thickness of sea ice. Eighteen images of EOS MODIS L1B data in the 2009–2010 winter were used to e...

This document describes the algorithms for simultaneous remote sensing of aerosol from EOS-MODIS over land and ocean. The algorithm will be used to monitor the aerosol optical thickness (proportional to the aerosol total loading) and size distribution (integrated on the vertical column) of the ambient (undisturbed) aerosol, over most of the globe (oceans and the moist parts of the continents) o...

Lead selenide films are prepared by the vacuum evaporation technique on clean glass substrates held at room temperature in a vacuum 10 torr. The thickness of the film is measured by employing quartz crystal monitor technique. EDAX analysis confirms the composition of constituent in the PbSe thin films. The electrical resistivity measurements as a function of temperature in the range 303 K 483 K...

Chemical deposition techniques as well as diffusing techniques can be used to produce inhomogeneous composite films. We put forth a theory to investigate the nonlinear ac responses of a model graded film. We find that the responses are strongly dependent on the gradation profile and the thickness of the film, due to the local field effect. Thus, it seems possible to real-time-monitor the gradat...
