A hybrid CDMA-FDMA indoor microcellular scenario
5th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Wireless Networks - Catching the Mobile Future., 2002An indoor communication channel is characterised by large propagation losses, slow time variations, a multipath nature and fading. We present a new cellular concept for indoor communications. A concentric circular model is the basic cell structure which consists of two or three concentric zones, operating in different frequencies, under the CDMA ...

Italian hybrid and fission reactors scenario analysis
AIP Conference Proceedings, 2012Italy is a country where a long tradition of studies both in the fission and fusion field is consolidated; nevertheless a strong public opinion concerned with the destination of the Spent Nuclear Fuel hinders the development of nuclear power. The possibility to a severe reduction of the NSF mass generated from a fleet of nuclear reactors employing an ...

Futures literacy: A hybrid strategic scenario method
Futures, 2007Abstract What stories do we tell about the future? This article develops a topology of storytelling about the future, which is used to develop a definition of ‘futures literacy’. It goes on to outline a hybrid strategic scenario method for acquiring the capacities of futures literacy.

MIMO cooperative spectrum sensing in hybrid satellite/terrestrial scenario
2015 IEEE International Conference on Communication Workshop (ICCW), 2015In a hybrid satellite/terrestrial scenario, the paper analyzes the advantages of using a cooperative scheme combined with Multiple-Input Multiple- Output (MIMO) technologies at each cognitive radio (CR) node for spectrum sensing. In the proposed scenario, the satellite and the terrestrial components use the same band (primary users) and a group of ...

Development of 20s long hybrid scenarios on JET
2007This paper reports the results of recent experiments carried out at JET achieving a stationary hybrid scenario lasting 20s with βN≈2. 5 and H89≈2. Up to 186 MJ have been injected in the plasma via Neutral Beams, with a significant fraction (up to 50%) of current density driven non-inductively.
