Ports play an essential role in economic and trade, which is important node hub cargo transportation. The evaluation index of port competitiveness the efficiency collection distribution system. This paper analyzes development trend According to principle establishing index, a reasonable system transportation constructed. as whole. capacity, service level, coordination ability with external cond...

In this work we develop necessary and sufficient conditions for describing the family of anti-Hurwitz polynomials, introduced by Vergara-Hermosilla et al. in [1]. Specifically, studied a dual version Theorem Routh-Hurwitz present explicit criteria polynomials low order derivatives. Another contribution is establishing Hermite-Biehler Theorem. To aim, give extensions boundary crossing Theorems z...

Establishing appropriate inter-organizational partnership in disaster response is of great help to the improvement relief performance. However, selection proper organizations for government agencies build partnerships among numerous remains be addressed. To fill gap, this paper adopted a complex network modeling method explain formation mechanism response. Then, based on numerical simulation me...

Humans can learn in a matter of seconds to associate a response R with a stimulus S, following simple verbal instructions, e.g. “Press the right button when you see a green light”. This involves establishing links through several neural relays, from visual to motor representations. There is no model of fast learning in such systems. This paper describes a new architecture and learning principle...

First, likelihood ratio statistics for checking the hypothesis of equal variances of two-dimensional Gaussian vectors are derived both under the standard ( σ 2 1 , σ 2 2 , ) -parametrization and under the geometric (a, b,α)-parametrization where a2 and b2 are the variances of the principle components and α is an angle of rotation. Then, the likelihood ratio statistics for checking the hypothesi...
