Northwest University for Nationalities is the first minority institution of higher learning founded in China after the establishment of the People's Republic of China, directly under the State Ethnic Affairs Commission of PRC. Its precedent was the third campus of Northwest People's Revolutionary University in Lanzhou. From February 1950, the school was planned on the basis of that campus. In August 1950, Northwest Nationalities College was founded, and a senior CPC leader, Wang Feng, became the first president. In April 2003, approved by Ministry of Education and State Ethnic Affairs Commission, the school adopted the current name, Northwest University for Nationalities.The University is located in Lanzhou, Gansu Province, and covers a land area of 474 acres . It has two campuses: Northwest Xincun and Yuzhong.The University created the first internet website in Tibetan in the world.The following 6 journals are edited and published by the University:Northwest Minorities Research, Journal of Northwest University for Nationalities , Journal of Northwest University for Nationalities Journal of Northwest University for Nationalities Journal of Northwest University for Nationalities Northwest University for Nationalities Tabloid↑ Wikipedia.

Highly conductive PPy/graphene nanosheets/rare earth ions (PPy/GNS/RE 3+) composites were prepared via in situ polymerization with p-toluenesulfonic acid as a dopant and FeCl3 as an oxidant. The effects of GNS and RE3+ on the electrical conductivity of the composites were investigated. The results showed that the GNS as a filler had effect on the conductivity of PPy/GNS/RE3+ composites, which played an important role in forming a conducting network in PPy matrix. The microstructures of GNS and PPy/GNS/RE3+ were characterized by the SEM and TEM examinations. It was found that GNS and PPy nanospheres formed a uniform composite with the PPy nanospheres absorbed on the GNS surface and/or filled between the GNS. Such uniform structure together with the observed high conductivities afforded high specific capacitance when used as supercapacitor electrodes. A specific capacitance of as high as 238 F/g at a current density of 1 A/g was achieved over the PPy/GNS/Eu3+ composite. © 2013 Elsevier B.V. Source

Systems as diverse as genetic networks or the World Wide Web are best described as networks with complex topology. A common property of many large networks is that the vertex connectivities follow a scale-free power-law distribution. This feature was found to be a consequence of three generic mechanisms: (i) networks expand continuously by the addition of new vertices, (ii) new vertex with different number edges of weighted selected that connected to different vertices in the system, and (iii) new vertices attach preferentially to sites that are already well connected. A model based on these three ingredients reproduces the observed stationary scalefree distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems. © (2012) Trans Tech Publications, Switzerland.

This article mainly focused on the issues often encountered in input of embedded devices, and provided detailed analysis combined with successful experience of Tibetan QWERT keyboard layout, in accordance with the principles of ergonomics, quick-input. The layout of the digital keyboard has been done on the basis of this research. The Main research and analysis were: Selecting the most common corpus materials in Tibetan language (over 3.6million pieces) as the training set; Conducting cluster analysis with SPASS after integrating the importance and statistics of the corpus materials in Tibetan language; Improving the model with artificial intelligence method and obtaining the final model; IV Determining evaluation criteria. This design has complied the simulation for test input program, as well as selected different themes of the test corpus materials in Tibetan language for the simulated keyboard input process and obtained evaluation results. Eventually, through the analysis of the results, to determine the evaluation criteria of the final layout for the Tibetan digital keyboard. Source

This paper is concerned with the asymptotic behavior on ∂Ω of boundary blow-up solutions to semilinear elliptic equations (Formula Presentd), where b(x) is a nonnegative function on Ω and may vanish on ∂Ω at a very degenerate rate; f is nonnegative function on [0,∞) and normalized regularly varying or rapidly varying at infinity. The main feature of this paper is to establish a unified and explicit asymptotic formula when the function f is normalized regularly varying or grows faster than any power function at infinity. The effect of the mean curvature of the nearest point on the boundary in the second-order approximation of the boundary blow-up solution is also discussed. Our analysis relies on suitable upper and lower solutions and the Karamata regular variation theory. © 2016, Springer International Publishing. Source

Swarm stability is studied for descriptor compartmental networks with linear time-invariant protocol. Compartmental network is a specific type of dynamical multi-agent system. Necessary and sufficient conditions for both consensus and marginal swarm stability are presented, which require a joint matching between the interactive dynamics of nearest neighbouring vertices and the Laplacian spectrum of the overall network topology. Three numerical instances are provided to verify the theoretical results. © The Institution of Engineering and Technology 2015. Source
