智能DNS和线路跟随解析技术在多出口高校校园网中的应用

目前有比较多的高校接入包含中国教育和科研计算机网在内的多个因特网服务提供商,且校园网各服务器主要使用教科网IP,导致了非教科网用户存在跨网访问校园网服务器速度慢及校内用户访问采用内容分发技术（CDN）的大型网站较慢的问题.为此提出了校园网智能DNS和线路跟随解析技术解决方案,并给出关键的配置示例.     

大桃儿沟第9窟八十四大成就者图像考释

大桃儿沟石窟位于吐鲁番盆地火焰山西段的大桃儿沟内,现存10个洞窟,是一处藏传佛教石窟。其中,第9窟两侧壁为八十四位大成就者图像。与西藏江孜白居寺以及莫高窟第465窟四壁下部的大成就者图像对比可知,大桃儿沟第9窟的图像与莫高窟第465窟更加接近,均出现了执镜师的图像（不见于江孜白居寺）。这隐约表明它们的绘画底本为同一个版本,可见莫高窟第465窟八十四大成就者图像是大桃儿沟第9窟的源头,这是宋元时期藏传佛教向西传播的一个鲜明例证。     

The Matrix and Critical Theory's Desertion of the Real

This article uses the narratives of the popular films The Matrix, Matrix: Reloaded, and Matrix: Revolutions as a lens through which to discuss the problems of the real and human agency in contemporary critical theory. Alongside a reading of the films’ invocations of social theory, the article describes parallel academic theories whose strongest structuralist and poststructuralist manifestations abandon conceptions of the real and willful human agency. In a field whose pessimistic narrative of Marxism often begins with anti-humanist structuralism, classical Marxist discourse theories offer a viable standpoint-based concept of reality upon which to found solidaristic human action.     

Writing culture; inscribing lives: a reflective treatise on the burden of representation in native research

This paper complicates the contested assumptions surrounding native research by exploring the burden of representation placed on native researchers because they are seen as insiders. This particular issue of representation is important for native researchers to consider, especially in instances where the research is on an understudied or politically charged group, because of the ways in which the socio-political climate influences both the telling and the reading of such research. Drawing on the author’s personal struggles as a Pakistani researcher conducting ethnographic research with Pakistani immigrants in the United States in the post-9/11 climate, this paper explores and critiques the role of the native researcher and the issues involved with representing understudied groups. Specifically, the paper focuses on authenticity, positionality, audience, and accountability. Thus, the paper is a call for researchers to be more reflective and to think more deeply about their positionality and its impact on the various constituents as they research and write. To encourage such reflexivity, the article provides a set of questions for researchers to consider at different stages of the research and writing process.     

Defining and Applying Idea Technologies

Abstract

In this paper we define and explain idea technologies, illustrate how they operate in learning environments, then present and explore the pedagogical advantages of using our three-tiered, idea-technology classification system. We believe it will serve as an introductory primer, or conceptual framework, for university professors, educational technologists, teacher educators, and university administrators. Like any sound grammar, we believe our conceptual framework not only provides structure, economy, and flexibility, but also possesses the added benefit of never “crashing” as it improves teaching and learning.     

求实对称三对角矩阵特征值的递归算法

许多对称矩阵特征值问题最后归结为解实对称三对角矩阵特征值问题。在文章中为区间分半法(二分法)求实对称三对角矩阵特征值设计了一个递归算法。用一个递归函数可以求出所有特征值,且能求重特征值。

Mixed control of uncertain jumping time-delay systems

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.
