The use of plasmas in aerodynamics has become a recent topic of interest. The potentialities of different types of plasmas are being investigated for low velocity and high velocity flow control, as well as for plasma-assisted combustion. Dielectric barrier ...
Engineering return stroke models can be categorized either as current generation (traveling current source type) models or current propagation (transmission line type) models. The current generation models are described among other parameters by a corona c ...

This paper deals with the assessment of the lightning performance of distribution lines, namely the estimation of the annual number of lightning-induced flashovers versus the critical flashover voltage of the line insulators. The procedure proposed by the ...
A detailed investigation of the electrical resistivity of a series of monovalent (Ag) doped polycrystalline La1−xAgxMnO3 pellets with x ranging from 0.05 to 0.30 and measured over the temperature range between 10 and 350 K is reported. La1−xAgxMnO3 compoun ...
The dynamics of the rotating vortex taking place in the discharge ring of a Francis turbine for partial flow rate operating conditions and cavitation free conditions is studied by carrying out both experimental flow survey and numerical simulations. 2D las ...
In this paper, the RF Breakdown power threshold in arbitrary complex components based on rectangular waveguide technology is investigated. In particular, multipactor (in vacuum) and corona discharge (close to the Paschen curve minimum) are analyzed. The ob ...
In this paper, a software tool for the prediction of the corona discharge and the multipactor thresholds in passive components based on rectangular geometry for space applications is presented.The software tool has been compare to measurements showing a ve ...
Regions of positive slope in the pressure-discharge characteristics are one of the major concerns in design and operation of centrifugal pumps, as they are limiting the admissible operating range to values above the critical discharge. The industrial pump ...
We discuss the spectral signatures of strong electronic correlations and electron-phonon interactions in two representative low-dimensional systems. In the 2D compound 1T-TaSe2 a charge-density-wave (CDW) induces a narrowing of the conduction band, which t ...
Conductive atomic force microscopy (C-AFM) was used to study the dielectric breakdown of SiO/sub 2/ layers at a nanometric scale. First, bare oxide regions were stressed and broken down using the tip as the metal electrode of a MOS structure. The results s ...
