Application of fast fourier transform cross-correlation for the alignment of large chromatographic and spectral datasets
No full textPreprocessing of Chromatographic and spectral data is an important aspect of analytical sciences. In particular, recent advances in proteomics have resulted in the generation of large data sets that require analysis. To assist accurate comparison of chemical signals, we propose two methods for the alignment of multiple spectral data sets. Based on methods previously described, each Chromatograph or spectrum to be aligned is divided and aligned as individual segments to a reference. However, our methods make use of fast Fourier transform for the rapid computation of a cross-correlation function that enables alignments between samples to be optimized. The proposed methods are demonstrated in comparison with an existing method on a chromatographic and a mass spectral data set. It is shown that our methods provide an advantage of speed and a reduction of the number of input parameters required. The software implementations for the proposed alignment methods are available under the downloads section at http://ptcl.chem.ox.ac.uk/~jwong/specalign. © 2005 American Chemical Society
Longitudinal Variation of HO Ice Absorption on Miranda
No full textMany tidally locked icy satellites in the outer Solar System show
leading/trailing hemispherical asymmetries in the strength of near-infrared
(NIR) HO ice absorption bands, in which the absorption bands are stronger
on the leading hemisphere. This is often attributed to a combination of
magnetospheric irradiation effects and impact gardening, which can modify grain
size, expose fresh ice, and produce dark contaminating compounds that reduce
the strength of absorption features. Previous research identified this
leading/trailing asymmetry on the four largest classical Uranian satellites but
did not find a clear leading/trailing asymmetry on Miranda, the smallest and
innermost classical moon. We undertook an extensive observational campaign to
investigate variations of the NIR spectral signature of HO ice with
longitude on Miranda's northern hemisphere. We acquired 22 new spectra with the
TripleSpec spectrograph on the ARC 3.5m telescope and 4 new spectra with GNIRS
on Gemini North. Our analysis also includes 3 unpublished and 7 previously
published spectra taken with SpeX on the 3m IRTF. We confirm that Miranda has
no substantial leading/trailing hemispherical asymmetry in the strength of its
HO ice absorption features. We additionally find evidence for an
anti-Uranus/sub-Uranus asymmetry in the strength of the 1.5-m HO ice
band that is not seen on the other Uranian satellites, suggesting that
additional endogenic or exogenic processes influence the longitudinal
distribution of HO ice band strengths on Miranda.Comment: 40 pages, 19 figures. Accepted for publication in PS

Developing a multimodal biometric authentication system using soft computing methods
No full textRobust personal authentication is becoming ever more important in computer-based applications. Among the several methods, biometric offers several advantages, mainly in embedded system applications. Hard and soft multi biometric, combined with hard and soft computing methods can be applied to improve the personal authentication process and to generalize the applicability.
This chapter describes the embedded implementation of a multi biometric (voiceprint and fingerprint) multimodal identification system based on hard computing methods (DSP) for features extraction and matching, an artificial neural network (ANN) for soft feature pattern matching, and a fuzzy logic engine (FLE) for data fusion and decision

A Short Proof of the Cartwright-Littlewood Fixed Point Theorem
No full textThe purpose of this paper is to give a short proof of the Cartwright-Littlewood
fixed point theorem (2, p. 3, Theorem A).Theorem A. If T is a (1-1) continuous and orientation preserving transformation of the Euclidean plane E onto itself which leaves a bounded continuum M invariant and if M does not separate E, then some point of M is left fixed by T.</jats:p
