Identification of spectral lines of elements using artificial neural networks
Microchemical Journal, 2009Artificial neural networks (ANNs) are relatively new computational tools that have found extensive utilization in solving many complex real-world problems. This paper describes how an ANN can be used to identify the spectral lines of elements. The spectral lines of Cadmium (Cd), Calcium (Ca), Iron (Fe), Lithium (Li), Mercury (Hg), Potassium (K) and ...

Automatic impurity spectral line identification algorithm with noise reduction for fusion plasmas
Fusion Engineering and Design, 2020Abstract Accurate diagnostics of impurity behavior inside the tokamak plasma is essential for long and stable plasma operation and also for machine protection in fusion devices including ITER. In this study, a numerical code for identifying impurity line spectra was developed and assessed by utilizing the ITER-relevant vacuum ultraviolet (VUV ...

On the use of perceptual Line Spectral Pairs Frequencies for speaker identification
2010 National Conference On Communications (NCC), 2010Line Spectral Pairs Frequencies (LSFs) provide an alternative representation of the linear prediction coefficients. In this paper an investigation is carried out for extracting feature for speaker identification task which is based on perceptual analysis of speech signal and LSF.

A multiple choice greedy algorithm for resolution improvement of spectral lines identification
2012 10th International Symposium on Electronics and Telecommunications, 2012The paper analyses the possibility to improve the resolution of spectral lines identification based on zero-padding Discrete Fourier Transform (DFT), by using a sparse vector estimation technique. A variant of the Orthogonal Matching Pursuit (OMP) algorithm called ‘Multiple Choice OMP (MCOMP)’ is proposed. This algorithm considers the difficulty arisen

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.

Automated spectral line identification
Publications of the Astronomical Society of the Pacific, 1990Software has been developed to automate the intricate and tedious process of stellar line identification. A set of unknown stellar wavelengths and intensities is compared with a master multiplet list composed of the Revised Multiplet Table plus extensions.

Journal of Applied Physics, 2022
The process of associating spectral peaks in emission radiation data with particular charge states of specific elements is a common task in the field of plasma diagnostics in both laboratory and astrophysical settings. Existing techniques for this purpose are often highly manual or can rely heavily on theoretical models and assumptions of plasma ...
