In a directed graph D, given two distinct vertices u and v, the line defined by ordered pair (u,v) is set of all w such that u,v belong to shortest path in containing from v. this work we study following conjecture: number lines any strongly connected at least its vertices, unless there vertices. Our main result tournament satisfies conjecture; also prove for bipartite tournaments diameter most...

Oprea proves that Ric(X) ≤ n−1 4 (c + n||H||) improving the Chen-Ricci inequality for Lagrangian submanifolds in complex space forms by using an optimization technique. In this article, we give an algebraic proof of the inequality and completely classify Lagrangian submanifolds in complex space forms satisfying the equality, which is not discussed in Oprea’s paper.

Chen Shui-bian achieved an international reputation for his promotion of Taiwan independence. Whilst that reputation may have been well earned, the analyses on which this conclusion is based are frequently flawed in two ways. First, by using an undifferentiated notion of independence, they tend to conflate sovereignty with less threatening expressions of Taiwanese identity and pro-democracy dis...

An image compression system based on transform coding and zonal sampling is presented. It is based on the wellknown Chen-Smith coder, but with an improved technique for transform coefficient quantization and the replacement of the discrete cosine transform (DCT) by the lapped orthogonal transform (LOT). The system leads to signal-to-noise ratios that are from 1.5 to 2.0 dB above those obtained ...

The article analysed the parallel programming mode of cloud computing. In order to increase solution rate of real-time optimization model, the article also proposed parallel genetic algorithm in the cloud computing environment. The article also reaserched on real time optimization vehicle routing problem of cold chain logistics distribution based on cloud computing and simulated on the issue. T...
