Terahertz (THz) spectroscopy, and especially THz imaging, holds large potential in the field of nondestructive, contact-free testing. The ongoing advances in the development of THz systems, as well as the appearance of the first related commercial products, indicate that large-scale market introduction of THz systems is rapidly approaching. We review(More)
"Differential mortality in Norway has been studied on the basis of a sample of data derived from the linkage of the 1960, 1970, and 1980 censuses to vital registration records. Based on the hypothesis that the determinants of survival act in interaction, two models are proposed. The first is based on states defined at each observation period by the(More)
We have designed and performed an experiment that permitted direct observation of Brillouin backscattering in an Yb-doped double-clad fiber laser. Fifteen Brillouin-shifted frequencies were observed for the first time to our knowledge. We clearly demonstrate that stimulated Brillouin scattering is directly responsible for both fast transient dynamics of the(More)
This approach aims to combine the Kohonen map abbreviates in SOM (Self Organizing Map), as a powerful tool for recognition, with the binary technique of signal processing by wavelet packets for noise removing. The obtained model can be applied successfully to solve the phonemic recognition problem, pronounced by multi speaker in varying environmental(More)
