Automatic testing of high resolution time digitizers

Frequency-domain testing of waveform digitizers

An easy to use, robust and accurate frequency-domain procedure for estimating the spectral performance of waveform digitizers is considered in this paper. Its properties are analyzed and almost unbiased estimators are proposed along with simple but accurate expressions for their variances. Experimental results are presented to validate the proposed analysis. Directions and criteria useful for t...

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

Automatic abundance analysis of high resolution spectra

We describe an automatic procedure for determining abundances from high resolution spectra. Such procedures are becoming increasingly important as large amounts of data are delivered from 8m telescopes and their high-multiplexing fiber facilities, such as FLAMES on ESO-VLT. The present procedure is specifically targeted for the analysis of spectra of giants in the Sgr dSph; however, the procedu...
