An improved macro traffic flow model is presented in this paper. According to the improved model and phase plane diagrams, the stability analysis of various traffic phenomena can be carried out directly. There is a one-toone relationship between the traffic congestion and the unstable system in the phase plane. In order to illustrate this new method further, the well-known stop-and-go waves are analyzed...
Summary form only given. While dielectric barriers are not essential for the generation of radio-frequency atmospheric glow discharges, they have been shown recently to be effective for sustaining radiofrequency atmospheric plasmas in regimes of large discharge currents. In this contribution, we present results of an experimental study of a radio-frequency dielectric barrier discharge generated in...
Summary form only given. Cold atmospheric plasma jets have shown considerable promise for many industrial and medical applications. However, their fundamental studies are much behind. In this contribution, we present a preliminary study of a cold atmospheric plasma jet struck inside a ceramic tube and ejected into its surrounding ambient air. Both helium and argon are used as the working gas. The...
Summary form only given. Atmospheric pressure glow discharges (APGD) generated at radio frequencies generally employ naked electrodes, since the rapid oscillation of the applied voltage suppress very effectively a sustained energy supply to an unrestricted current growth. Consequently, RF APGD are typically stable and it is usually unnecessary to insulate electrodes with dielectric barriers - a common...
Summary form only given. Radio-frequency atmospheric-pressure glow discharges (APGD) have been used in a wide range of applications including etching, deposition, surface sterilization and biological manipulation. Most RF APGD are generated at 13.56 MHz, of which the current understanding is sound and the application prospect is excellent. Recently we have shown that plasma stability of RF APGD can...
