LF in LF: Mechanizing the Metatheory of LF in Twelf

We present a mechanized proof of the metatheory of LF, i.e. the decidability of typechecking and the existence and uniqueness of canonical forms. We use a syntactic approach in which we define a translation from LF to its canonical forms presentation (in which only beta-short, eta-long terms are well-formed) and prove soundness and completeness of the translation, establishing that definitional...

Modeling Surface Discharge Effects of Atmospheric RF on Gas Flow Control

The advantages of plasma actuators for flow control are being increasingly recognized in the literature in all speed regimes encountered in aerospace applications. Recent experiments with suitably configured atmospheric RF discharges have demonstrated particularly striking effects by reducing or eliminating separation in low-speed flows. In this paper, a finite-element multi-fluid formulation i...

Electrical Characterization of Atmospheric Pressure Gaseous Discharge

This paper reports the generation of atmospheric pressure gaseous discharge and its electrical characterization. For this purpose, a point-plane electrode system has been fabricated. A high voltage power supply (0-11 kV, 50 Hz) was applied across the electrodes. Discharge was generated with and without the dielectric barrier between the electrodes. The gas discharge was seen as in-homogenous fi...

The Role of Secondary Electrons in Low Pressure RF Glow Discharge

We concerned on the role of secondary electrons in low pressure rf glow discharge. The Particle in Cell/Monte Carlo computer simulations (PIC/MC) was applied to simulate the discharge. The influence of secondary electron emission yield (SEY) on the plasma density was studied. Furthermore the relative density and the electron energy probability function of secondary particles, i.e., secondary el...
