We have observed the soft X-ray spectrum of highly ionised silicon and made measurements of the lifetime of the helium like system. Standard beam foil decay curve techniques were used and the 3 ~ 1 decay to the ground state was observed with a curved crystal X-ray spectrometer. A preliminary result of 6.68 f 0.40 ps was obtained which compares with theoretical estimates of 6.33 ps and 6.62 ps. ...

In order to study the heteroepitaxial growth of gallium arsenide on silicon(100), Small Angle X-ray Scattering (SAXS) experiments have been performed at the synchrotron radiation facility Photon Factory at KEK. The samples studied have been grown by both Atomic Layer Epitaxy and Metal-Organic Chemical Vapor Deposition. The two dimensional SAXS patterns present different features depending on th...

This paper deals with the unsupervised segmentation of astronomical multiband images. Most of these images have the particularity to be quantized on float numbers with large luminance range, on different wavelengths. These characteristics require to manipulate large amount of extremely accurate data on each spectral band, which is very different to the case of 8-bits-integer coded pixels. We pr...

types of capacitor construction and effects on power loss and power dissipation. Outline ways to manage power loss, with emphasis on the capacitors Equivalent Series Resistance (ESR). Review the key elements for modeling the capacitor by applying S2P files for impedance calculations.
