Reversed Field Pinch (RFP) plasmas exhibit a broad spectrum of MHD activity. The instability underlying much of this activity in the standard RFP discharge has been identified as resistive tearing and is well modelled by nonlinear, resistive MHD. In recent years two additional types of discharge have been produced: those with reduced tearing activity leading to improved confinement and those wi...

I begin by stating that I have not regretted coming back to Greece after 17 years of working abroad and that I have no plans to seek employment in another country. I still enjoy both living in and doing science in Greece. Having said that, let me say that most non-Greeks to whom I describe my life as a researcher tend to see in me a clear-cut case of schizophrenia. How can one plan anything in ...

Moving from the doctoral student role to the faculty member role is a challenging transition. Strategies that motivate and help keep scholarship moving forward can be invaluable in helping make the transition successful. The authors discuss 2 visual tracking strategies to promote the forward movement of scholarship. A whiteboard (dry erase) and a publication trajectory table to track manuscript...

Tearing mode stability analysis in the presence of circulating energetic ions (CEI) is studied in the reversed field pinch (RFP) magnetic configuration. In contrast to the minimal effect of precessional drift of CEI on tearing modes in tokamaks, the effect of precessional drift of CEI on tearing modes is important in the RFP. It is found that the effects of CEI on tearing modes in RFP depend on...

We are developing mixed-initiative systems that provide users with exible control over evolving processes. For such systems to be feasible, both users and automated agents must be able to operate at multiple levels of abstraction. We are designing mixed initiative systems organized around shared task models to achieve this multi-level task sharing. These task models will allow both human and au...

in december 1953, the us president, general dwight d. eisenhower delivered his “atoms for peace” speech at the united nations' general assembly, which called for the promotion of peaceful uses of nuclear energy under special international agency. this proposal became the starting point for creating the iaea in 1957 and adopting npt in 1968. the atoms for peace initiative established the pr...
