Authenticity of the traditional Cypriot spirit "zivania" on the basis of metal content using a combination of coupled plasma spectroscopy and statistical analysis
(2003)Sixty-eight alcoholic beverages ranging in alcoholic degree between 40 and 55 from different countries were analyzed for their 16 most abundant metal elements using inductively coupled plasma (ICP) spectroscopy. The results ...

Bootstrap confidence bands for spectra and cross-spectra
(Publ by IEEE, 1989)Summary form only given. Nonparametric bootstrap confidence intervals and bands have been constructed from kernel and lag-window spectral estimators. The results can be of use in a finite sample situation, especially when ...

Bootstrap confidence bands for spectra and cross-spectra
(1992)A new nonparametric method for setting confidence intervals and confidence bands for spectra and cross-spectra of stationary weakly dependent time series is presented. The proposed methodology involves using a bootstrap ...

A conforming spectral collocation strategy for Stokes flow through a channel contraction
(1991)A spectral collocation method is described for solving the stream function formulation of the Stokes problem in a contraction geometry. The flow region is decomposed into a number of conformal rectangular subregions. A ...

Reactivation of an aged commercial three-way catalyst by oxalic and citric acid washing
(2006)The efficiency of dilute oxalic and citric acid solutions on improving the oxygen storage capacity (OSC) and catalytic activity of a severely aged (83 000 km) commercial three-way catalyst (TWC) has been investigated. ...

Uranium levels in Cypriot groundwater samples determined by ICP-MS and α-spectroscopy
(2013)The uranium concentration and the isotopic ratio 238U/234U have been determined in Cypriot groundwater samples by ICP-MS after ultrafiltration and acidification of the samples and α-spectroscopy after pre-concentration and ...
