3C 273 is the most extensively studied quasar both from the ground and from space. Recent satellite observations have given important information on the overall electromagnetic spectrum of 3C 273 in the 3'-ray, X-ray, and UV ranges. The most salient results are: (i) the energy per decade of frequenc

In this paper we present a review of some recent results for identification of linear dynamic systems in the presence of unknown but bounded uncertainty. We make reference to the optimal algorithms theory which provides a general unifying framework to deal with several typical problems of system id
## Appearance potential spectroscopy (APS) was introduced in the early seventies as a relatively simple surface sensitive analytical technique. Later, various processes involved in APS signal formation have been investigated, making use of sophisticated experimental set-ups. In this way, APS became
## Abstract Solid–solid and gas–solid self‐propagating high temperature reactions are exploited for interesting and relatively new technological applications in the field of combustion synthesis. This paper describes the characteristics of this technique by focusing on the synthesis of some reactin
