An infrared view of Wolf-Rayet WC subtypes - I. Line identification and spectral characteristics
Monthly Notices of the Royal Astronomical Society, 1991High-resolution (R ∼ 300-600) infrared (1.0-3.4 μm) spectra of a sample of Wolf-Rayet stars of subtypes WC5-9 are presented. The line identifications are thoroughly discussed and some 20 new identifications given, notably the C IV 4p-4s doublet at 1.435 μm, observed previously but not identified, H I 5p-3d (at 1.299 μm), He II 17-7 (at 1.344 μm), He II

A study of spectral line identifications in perseid meteor spectra
1961A detailed lisl of spectral line idenlifirations is derived from the study of five Perseid meteor spectra. A total of 229 features are identified in the region from 3680 A to 8710 A. lt is shown that lines of N II, O II, and Sr II are present, and probably also lines of Sr I, Ba I, and Ba II, in addition to lines of other atoms and ions previously ...

Spectral line shape identification by using fractional derivative spectrometry
2004Before it is difficult to say about a peak shape without conducting additional research. Conventional nonlinear fitting methods based on the OLS approach are unsuitable to unambiguously assign the overlapped peaks. This implies that a composite band can be decomposed into elementary components of a given shape with the same integral reconstruction ...

Robust time-variant AR spectral identification for on-line frequency analysis of HRV signal
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002The frequency analysis of the heart rate variability signal can be achieved on a beat-to-beat bases through AutoRegressive spectral estimation implemented in recursive form; thus the spectral parameters of clinical and physiological interest are obtained continuously in time. In on-line applications, however, the presence of artifacts in the signal may

On the identification of Fe ix and Ni xi lines from coronal spectral
Solar Physics, 1975Identifications of coronal lines with transitions of Fe ix and Ni xi, as proposed by Wagner and House, and Svensson, Ekberg and Edlen, are checked by means of line intensity ratios, from observations obtained at the 1965 eclipse. All the suggestions of Svensson, Ekberg and Edlen are suitable.
