Extracting Stellar Parameters from Observed Spectra: the Role of Cross-correlation and Minimum Distance Methods
One may consider cross-correlation routines applied to stellar spectra as a way to determine not only the radial velocities but also to assess the properties of stellar atmospheres. We show that this is not the case. High value of the cross-correlation coefficient between the observed and a template spectrum does not mean that the template corresponds to correct values of stellar temperature, g...
متن کاملCross Time Frequency Spectra Applied to Automotive Brake Noise
We apply a local cross-correlation method to the study of correlating brake sounds perceived inside a car to the vibration produced by the brakes at the source. The method allows one to correlate the time-varying spectral properties of two vibration or acoustic sources. The aim is to identify the possible objectionable sounds by determining the time-varying frequencies that the two sounds have ...
متن کاملA Study of Cross-correlation and Breakfinding Algorithms Applied to the Measurements of Redshifts in Very Low Resolution Spectra
In this article we compare the cross-correlation and breakfinder techniques applied to the measurements of redshifts from low-resolution spectra. We assume spectra obtained from multinarrowband imagery, a technique for multi-object spectrophotometry. Comparing the cross-correlation with the breakfinder, we find that neither is intrinsically superior to the other. They have comparable precision ...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
