This paper presents the building and a first evaluation of a tones balanced Audio-Visual corpus of social affect in Vietnamese language. This under-resourced tonal language has specific glottalization and co-articulation phenomena, for which interactions with attitudes prosody are a very interesting issue. A well-controlled recording methodology was designed to build a large representative audi...

One of the most complicated decision making problems for managers is the evaluation of supply chain (SC) performance which involves various criteria. Though vast studies have been recorded on supply chain efficiency evaluation via balanced scorecard (BSC) approach, these studies do not focus on the relationships between the four perspectives of BSC approach. The present paper is an attempt focu...

In this paper we study the topology effects on diffusion process in signed networks. Considering a simple threshold model for diffusion process, it is extended to signed networks and some appropriate definitions are proposed. This model is a basic model that could be extended and applied in analyzing dynamics of many real phenomena such as opinion forming or innovation diffusion in social netwo...

For a graph G and not necessarily proper k-edge coloring c:E(G)→{1,…,k}, let mi(G) be the number of edges color i, call color-balanced if mi(G)=mj(G) for every two colors i j. Several famous open problems relate to this notion; Ryser's conjecture on transversals in latin squares, instance, is equivalent statement that properly n-edge colored complete bipartite Kn,n has perfect matching. We cont...
