The proximity effect is very significant to investigate transient peak voltages and EMC related problems of a conductor system. In this paper, effect of energized single conductor in close proximity of an Al plate when an Al plate is used as return path is investigated to find out proximity effect. The analysis involves simulation by the Finite Time Domain Method (FDTD) in comparison with field...

The transition to turbulence in pipe and plane Couette flow differs from the better understood situation of Taylor-Couette or Rayleigh-Bénard flow in that the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers. Moreover, even when turbulent flow is established, it can spontaneously return to laminar flow. These observations are compatible with the formation o...

Thermal management of electronics semiconductor technology is elixir to transform dream and imagination of the designers into reality. Motivation and need for research in development of novel cooling strategies for modern electronics is of paramount importance. Pulsating Heat Pipes, a novel research topic in heat pipe science, are new two-phase heat transfer devices that rely on the oscillatory...

In this paper the laminar flow in the rectangular channel bends is simulated using numerical techniques. The turning angle of the channel bend and the area ratio of the channel cross-section are two important parameters to be examined. For flow simulation, the body fitted 3-D continuity and momentum equations are used and a body fitted general purpose code is developed. The existing results of ...

An EPG-representation of a graph G is a collection of paths in a plane square grid, each corresponding to a single vertex of G, so that two vertices are adjacent if and only if their corresponding paths share infinitely many points. In this paper we focus on graphs admitting EPG-representations by paths with at most 2 bends. We show hardness of the recognition problem for this class of graphs, ...

We report on some extensions of the Kandinsky model: A new and highly nontrivial technique to incorporate nonplanar drawings into the Kandinsky model in the same way as in the GIOTTO approach is presented. This means a major step towards the practical usability of our approach. The used technique even gives new insights for the solvability of network ow problems. Another variant of Kandinsky en...
