Get PDFMultiresolution approach for period determination on unevenly sampled data
Get PDFIn this paper we present a multiresolution-based method for period
determination that is able to deal with unevenly sampled data. This method
allows us to detect superimposed periodic signals with lower signal-to-noise
ratios than in classical methods. This multiresolution-based method is a
generalization of the wavelet-based method for period detection that is unable
to deal with unevenly sampled data, presented by the authors in Otazu et al.
(2002). This new method is a useful tool for the analysis of real data and, in
particular, for the analysis of astronomical data.Comment: 6 pages, 3 figures, LaTeX, uses mn2e.cls. Accepted for publication in

Dioxins in Food and Feed - Reference Methods and New Certified Reference Materials (DIFFERENCE)
Get PDFThe European research project DIFFERENCE (“Dioxins in Food and Feed – Reference methods and New Certified Reference Materials”) was focussed on the development of an alternative methods for analysis of polychlorinated dibenzodioxins (PCDDs), dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) using comprehensive multi-dimensional gas chromatography (GC×GC), gas chromatography combined with low resolution ion-trap mass spectrometry (GCLRMS/ MS), the CALUX bioassay and an Ah-PCR technique. GC combined with high resolution mass spectrometry (HRMS) was used as a reference method in all comparisons
