Can you judge the love of a person? His affection? His intentions? The answer is a big No!. However, the bank balance, the assets and even the number of research papers can be measured. Marty Rubin once said “Every line is the perfect length if you don't measure it.” So, to every software developer his software would be just perfect if there is no metric to measure it. This premise compromises ...

|This paper describes an algorithm for nding all the perfect matchings in a bipartite graph. By using the binary partitioning method, our algorithm requires O(c(n+m) + n 2:5 ) computational e ort and O(nm) memory storage, (where n denotes the number of vertices, m denotes the number of edges, and c denotes the number of perfect matchings in the given bipartite graph). Keywords|bipartite graph, ...

In Gaussian elimination it is often desirable to preserve existing zeros (sparsity). This is closely related to perfect elimination schemes on graphs. Such schemes can be found in polynomial time. Gaussian elimination uses a pivot for each column, so opportunities for preserving sparsity can be missed. In this paper we consider a more flexible process that selects a pivot for each nonzero to be...

Properties of nonlinear perfect binary codes are investigated and several new constructions of perfect codes are derived from these properties. An upper bound on the cardinality of the intersection of two perfect codes of length n is presented, and perfect codes whose intersection attains the upper bound are constructed for all n. As an immediate consequence of the proof of the upper bound we o...

In this paper we introduce Digital Probability Hyper Digraph for modeling random variable as the hierarchical data-oriented model. Keywords—Data-Oriented Models, Data Structure, Digital Probability Hyper Digraph, Random Variable, Statistic and Probability.

In situ straining experiments were performed in a TEM on an equimolar CoCrFeMnNi (Cantor) high entropy alloy at room and cryogenic temperature. Perfect partial dislocation activity recorded both cases. Twinning directly follows the development of shearing that has various origins (perfect splitting, anchoring). It is shown that, although twinning more frequently observed liquid nitrogen tempera...
