We propose an enhanced design solution for embedded SRAM macros under dynamic voltage and frequency scaling (DVFS) environment. The improved wordline suppression technique using replica cellâ€¦ (More)

A circuit graph (G,C) is a 2-connected plane graph G with an outer cycle C such that from each inner vertex v, there are three disjoint paths to C . In this paper, we shall show that a circuit graphâ€¦ (More)

When we consider an embedding of graphs into a plane, it would be nice if it does not intersect internally since the embedding simply shows us the structure of graphs. It is easy to embed a tree intoâ€¦ (More)

In this paper, we introduce the notion of a pyramidal tour with step-backs which is an extension of a pyramidal tour. By using this idea we shall show that for a class of distance matrices an optimalâ€¦ (More)

The environmental problem in the earth such as acid rain is one of the important problem to be solved. Large amount of NOX is produced by electric power plants, ironworks and diesel engines, which isâ€¦ (More)

In this paper, we show that every 4-connected maximal plane graph with mfinite faces other than the octahedron can be drawn in the plane so that at least (m+3)/2 faces are acute triangles. Moreover,â€¦ (More)
