A Prufer-Sequence Based Representation of Large Graphs for Structural Encoding of Logic Networks
Manjari Pradhan, Bhargab B. Bhattacharya
The pervasiveness of graphs in today's real life systems is quite evident, where the system either explicitly exists as graph or can be readily modelled as one. Such graphical stru…
On Fault-Tolerant Design of Exclusive-OR Gates in QCA
Dharmendra Kumar, Debasis Mitra, Bhargab B. Bhattacharya
Design paradigms of logic circuits with Quantum-dot Cellular Automata (QCA) have been extensively studied in the recent past. Unfortunately, due to the lack of mature fabrication s…
On Chord and Sagitta in : An Analysis towards Fast and Robust Circular Arc Detection
Sahadev Bera, Shyamosree Pal, Partha Bhowmick +1
Although chord and sagitta, when considered in tandem, may reflect many underlying geometric properties of circles on the Euclidean plane, their implications on the digital plane a…
On Covering a Solid Sphere with Concentric Spheres in
Sahadev Bera, Partha Bhowmick, Bhargab B. Bhattacharya
We show that a digital sphere, constructed by the circular sweep of a digital semicircle (generatrix) around its diameter, consists of some holes (absentee-voxels), which appear on…
