A Web Server Cluster Solution Based on Twitter Storm  [PDF]
Xiaoling Xia, Lin Tian
Journal of Data Analysis and Information Processing (JDAIP) , 2014, DOI: 10.4236/jdaip.2014.21002

Single Web server would become a bottleneck that influences the availability and stability of Web service. Ten years ago, what had been proposed is to add Web servers for resolving this problem—Web Server Cluster. In recent years, the concept of cloud computing has got rapid development, and is becoming the future development trend of the IT industry. One of the characteristics of cloud computing is putting lots of computing resources together to provide users with a unified service. In this paper, we have proposed a new Cloud-Based Web Server Cluster Solution, based on the existing cloud computing model—Twitter Storm. It involves a new way to handle the web request from client and some other new features compared to the traditional Web Server Cluster. Combining with cloud computing, it would be the new trend of Web Server Cluster, and its feasibility is described in the paper too.

Abstract: Fluency as an acknowledged translation criterion has been in a dominant position in China for a long time. Translators have been striving for this fluency; readers and critics have been evaluating translated versions according to this criterion. But in translation history, even at the palm time of fluent translation, exceptions can still be found. Un-fluency as a translating strategy was frequently used and highly advocated by some important translators like LU Xun. The author of this paper has expected to explore the main reasons for LU Xun’s un-fluent translating strategy; find the specific translating methods applied in producing his un-fluent versions; and analyze the influence and significance of his un-fluent translation both on literary tradition and translation theory and practice. This paper attempts to make a descriptive study of un-fluent translation as a history phenomenon by taking LU Xun’s translation as a typical example. Key words: Deviation; Resistancy; LU Xun; Un-fluent Translation Résumé: La fluidité en tant qu’un critère de traduction reconnu est dans une position dominante en Chine depuis une longue période. Les traducteurs s’ efforcent d’atteindre cette fluidité; les lecteurs et les critiques évaluent la qualité des oeuvres traduites selon ce critère. Pourtant dans l'histoire de la traduction, même à l'époque d’or de la traduction fluide, il y a toujours des exceptions à trouver. L’un-fluidité a été fréquemment utilisée et hautement préconisée par certains traducteurs importants comme LU Xun comme une stratégie de traduction. L'auteur de cet article tente d'explorer les raisons principales de cette stratégie de LU Xun couramment traduction; de trouver les méthodes spécifiques appliquées dans sa traduction un-fluide, et d’analyser l'influence et l'importance de sa traduction laborieuse à la fois sur la tradition de traduction littéraire et sur la théorie de la traduction et de la pratique. Ce document tente de faire une étude descriptive sur la traduction un-fluide comme un phénomène historique en prenant la traduction de LU Xun comme un exemple typique. Mots-clés: déviation; résistance; LU Xun; traduction un-fluide
Teaching Primary Concepts of Translation through Cognition Models
Tian XIA
Studies in Literature and Language , 2010,
Abstract: This paper attempts to offer teachers effective and convenient models in explaining several basic concepts in translation theories to students in translation classes. Four models borrowed from the discipline of cognition are prototype, cognition domain, salience and the three-dimensional cognition mode. The concepts explained in this paper included translation variation, extra-linguistic knowledge for translation, translation criteria and un-translatability, all of which are among the primary concerns for students in translation classes. Key Words: translation concepts; translation theories; cognitive models

Conversation Analysis as Discourse Approaches to Teaching EFL Speaking
Cross-Cultural Communication , 2010, DOI: 10.3968/1005
Abstract: Conversation has been of primary interest to language researchers; since natural, unplanned, everyday conversation is the most commonly occurring and universal language “genre”, in that conversation is a speech activity in which all which all members of a community routinely participate Among approaches to discourse analysis in speaking, conversation analysis is one of the practical devices in teaching spoken English in EFL classroom. This paper tries to look at the theoretical basis for conversational analysis and explore the feasibility of applying a discourse approach to speaking in teaching a group of learners. Key words: Conversation Analysis; Discourse Approach; EFL; Spoken English Resumé: La conversation a été d'un intérêt primordial pour les chercheurs de langue, parce qu'une conversation naturelle, non planifiée et quotidienne est le genre de langue le plus fréquent et universel. La conversation est une activité de discours dans lequelle tous les membres d'une communauté participent régulièrement. Parmi les approches d'analyse du discours dans l'oral, l'analyse de conversation est l'un des dispositifs pratiques dans l'enseignement de l'anglais en oral pour les étudiants qui apprennent l'anglais comme une langue étrangère. Cet article tente d'examiner les fondements théoriques de l'analyse de conversation et d'explorer la possibilité d'appliquer une approche discursive à l'oral dans l'enseignement d'un groupe d'apprenants.Mots-clés: analyse de conversation; approche discursive; anglais en tant qu'une langue étrangère; anglais parlé
An improvement to TF-IDF: Term Distribution based Term Weight Algorithm
Tian Xia,Yanmei Chai
Journal of Software , 2011, DOI: 10.4304/jsw.6.3.413-420
Abstract: In the process of document formalization, term weight algorithm plays an important role. It greatly interferes the precision and recall results of the natural language processing(NLP) systems. Currently, TF-IDF term weight algorithm is widely applied into language models to build NLP Systems. Since term frequency is not the only discriminator which is necessary to be considered in term weighting and make each weight suitable to indicate the term’s importance, we are motivated to investigate other statistical characteristics of terms and found an important discriminator: term distribution. Furthermore, we found that, in a single document, a term with higher frequency and close to hypo-dispersion distribution usually contains much semantic information and should be given higher weight. One the other hand, in a document collection, the term with higher frequency and hypo-dispersion distribution usually contains less information.Based on this hypothesis, by leveraging the Pearson Chi-square Test Statistic, a Term Distribution based Local Term Weight Algorithm
Output-Feedback Synchronizibility of Linear Time-Invariant Systems
Tian Xia,Luca Scardovi
Mathematics , 2015,
Abstract: The paper studies the output-feedback synchronization problem for a network of identical, linear time-invariant systems. A criterion to test network synchronization is derived and the notion of output-feedback synchronizability is introduced and investigated. Sufficient and necessary conditions for synchronizability, implying that output-feedback stabilizability is sufficient but not necessary for synchronizability, are derived. In the special case of single-input single-output systems, conditions are derived in the frequency domain. The theory is illustrated with several examples.

Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B156

With the large-scale development of Chinese electric power, the contradiction of China’s energy supply and demand that reverse distributed is very prominent, therefore, promoting electricity trading is one of the important measures to get optimized configuration of energy resources in nationwide. For the two kinds of trading method, the “power point to the grid” trading and the “grid to grid” trading, this paper designed pricing mechanism model, and took one area as an example, we analyzed the impact of the participants by using different pricing mechanism, and put forward reasonable policy proposals for China’s pricing mechanism of trans-regional and trans-provincial electricity trading.

Network oscillations at the boundary of an equatorial coronal hole

Physics , 2009, DOI: 10.1051/0004-6361:200810124
Abstract: We investigate intensity oscillations observed simultaneously in the quiet chromosphere and in the corona, above an enhanced network area at the boundary of an equatorial coronal hole. A Fourier analysis is applied to a sequence of images observed in the 171 A and 1600 A passbands of TRACE. Four interesting features above the magnetic network are further investigated by using a wavelet analysis. Our results reveal that, in both the 171 A and 1600 A passbands, oscillations above the magnetic network show a lack of power at high frequencies (5.0-8.3 mHz), and a significant power at low (1.3-2.0 mHz) and intermediate frequencies (2.6-4.0 mHz). The global 5-min oscillation is clearly present in the 4 analyzed features when seen in the 1600 A passband, and is also found with enhanced power in feature 1 (leg of a large coronal loop) and feature 2 (legs of a coronal bright point loop) when seen in the 171 A passband. Two features above an enhanced network element (feature 3 and feature 4) show repeated propagating behaviors with a dominant period of 10 min and 5 min, respectively. We suggest these oscillations are likely to be slow magneto-acoustic waves propagating along inclined magnetic field lines, from the lower solar atmosphere into the corona. The energy flux carried by these waves is estimated of the order of 40 erg cm\^{-2} s\^{-1} for the 171 A passband and is far lower than the energy required to heat the quiet corona. For the 1600 A passband, the energy flux is about 1.4*10^6 erg cm\^{-2} s\^{-1}, which is about one third of the required energy budget for the chromosphere.
