XPS MultiQuant: multimodel XPS quantification software
A program for quantitative evaluation of x-ray photoelectron spectra has been developed to serve as a practical tool for surface chemists. The program uses the ‘classic’ approach of quantification and requires as input the integrated intensities of the measured XPS lines. The usual correction methods and factors can be applied and controlled independently. All necessary basic data for calculati...
متن کاملAdaptive smoothing of the log-spectrum with multiple tapering
A hybrid estimator of the log-spectral density of a stationary time series is proposed. First, a multiple taper estimate is performed, followed by kernel smoothing the log-multiple taper estimate. This procedure reduces the expected mean square error by (π 2 4) 4/5 over simply smoothing the log tapered periodogram. A data adaptive implementation of a variable bandwidth kernel smoother is given.
متن کاملPackage ‘ xps ’
Description The package handles pre-processing, normalization, filtering and analysis of Affymetrix GeneChip expression arrays, including exon arrays (Exon 1.0 ST: core, extended, full probesets), gene arrays (Gene 1.0 ST) and plate arrays on computers with 1 GB RAM only. It is an R wrapper to XPS (eXpression Profiling System), which is based on ROOT, an object-oriented framework developed at C...

The determination of the precise moment in which speech begins or ends is an important problem in ASR. As showed in [1], small separations from the optimum beginning and ending point, imply a great decrease in the recognition accuracy. The presence of noise [2] [3], specially when its level is high (around 95 dB as in the case of this work), and its characteristics are highly nonstationary, is ...
متن کاملImpedance-type measurements using XPS
An impedance type of measurement using X-ray photoelectron spectroscopy is applied for probing charging/discharging dynamics of a sample containing Rb deposited on a SiO2/Si substrate containing an octadecyltrichlorosilane (OTS) bilayer coating. The OTS bilayer coatings have possible use as antirelaxationwall coatings for alkali atom vapor cells inminiaturized instruments such as chip-scale ato...
