It is commonly recognized that the research on software architecture has enjoyed a golden age of innovation and concept formulation, and began to enter the mature stage of utilization. It is a natural expectation at present that the relevant concepts and methods have been populated and the improvements have been achieved in practice. In this paper, we give a retrospective report on our extensiv...

We consider a functional being a difference of two differentiable convex functionals on a closed ball. Existence and multiplicity of critical points is investigated. Some applications are given.

A graph G of order n is k-factor-critical, where k is an integer of the same parity as n with 0 ::; k ::; n, if G X has a perfect matching for any set X of k vertices of G. A k-factor-critical graph G is called minimal if for any edge e E E(G), G e is not k-factor-critical. In this paper we study some properties of minimally k-factor-critical graphs, in particular a bound on the minimum degree,...

A graph G is said to be n-factor-critical if G − S has a 1-factor for any S ⊂V (G) with |S| = n. In this paper, we prove that if G is a 2-connected n-factor-critical graph of order p with 3(G)¿ 2 (p−n−1), then G is hamiltonian with some exceptions. To extend this theorem, we de6ne a (k; n)-factor-critical graph to be a graph G such that G − S has a k-factor for any S ⊂V (G) with |S| = n. We con...

To cut down cost in a competitive environment, airlines must avoid delays and operation inefficiencies in both airside and landside. However, previous studies have paid little attention to an airlines’ ground operation in airports’ cargo terminals. The purpose of this paper is to demonstrate how to employ the Fuzzy Critical Path method (CPM) to find out airport’s ground critical operation proce...

This study provides an analysis of how the term “critical thinking” has been defined by authors articles published in Journal Media Literacy Education. It answers to three questions: (1) How frequently is mentioned scholars who write about media literacy?; (2) In what ways do convey meaning term?; and (3) To extent presented with a consistent meaning? While appeared more than half examined, the...
