We construct nonlinear super integrable couplings of the super integrable Dirac hierarchy based on an enlarged matrix Lie superalgebra. Then its super Hamiltonian structure is furnished by super trace identity. As its reduction, we gain the nonlinear integrable couplings of the classical integrable Dirac hierarchy. © 2012 Chinese Physical Society and IOP Publishing Ltd.

This paper proposes relaxed stabilization conditions of discrete-time nonlinear systems in the Takagi-Sugeno (T-S) fuzzy form. By using the algebraic property of fuzzy membership functions, a novel nonparallel distributed compensation (non-PDC) control scheme is proposed based on a new class of fuzzy Lyapunov functions. Thus, relaxed stabilization conditions for the underlying closed-loop fuzzy system are developed by applying a new slack variable technique. In particular, some existing fuzzy Lyapunov functions and non-PDC control schemes are special cases of the new Lyapunov function and fuzzy control scheme, respectively. Finally, two numerical examples are provided to illustrate the effectiveness of the proposed method. © 2012 IEEE.

University is one of the main sources of social human resource, it constantly supplies high-quality talents for our country. Recently, affected by economic crisis and some other factors, university students' employment problem has become one of the major problems which attract the government's attention. For solving this problem, it is necessary to evaluate the output efficiency of university human resource. In this paper, according to the statistical data of the year 2008, we use DEA method to analyze and evaluate the output efficiency, scale efficiency and deficiency of 42 "211" universities' human resources, and point out the improvement direction, it is very meaningful to perfect our output system of university human resource, increase the quantity and quality of our human resource and solve our university students' employment problem. © 2011 Published by Elsevier Ltd.

This article studies the adaptive output feedback control problem of a class of uncertain nonlinear systems with unknown time delays. The systems considered are dominated by a triangular system without zero dynamics satisfying linear growth in the unmeasurable states. The novelty of this article is that a universal-type adaptive output feedback controller is presented to time-delay systems, which can globally regulate all the states of the uncertain systems without knowing the growth rate. An illustrative example is provided to show the applicability of the developed control strategy. © 2012 Copyright Taylor and Francis Group, LLC.

The objective of this paper is to investigate the Fermions tunneling radiation of a new class of black holes in Einstein-Gauss-Bonnet (EGB) gravity and three-dimensional Lifshitz black hole in New Massive Gravity (NMG). As a result, the tunneling probability and Hawking temperature of the black holes are well recovered, which confirms that the Hawking temperature of emitted Dirac particles of the black holes are the same as in the case of scalar particles. The quantization of entropy from the black hole have also been discussed. © 2012 Springer Science+Business Media New York.
