  1. Uniform Page Migration Problem in Euclidean Space

    Directory of Open Access Journals (Sweden)

    Full Text Available The page migration problem in Euclidean space is revisited. In this problem, online requests occur at any location to access a single page located at a server. Every request must be served, and the server has the choice to migrate from its current location to a new location in space. Each service costs the Euclidean distance between the server and request. A migration costs the distance between the former and the new server location, multiplied by the page size. We study the problem in the uniform model, in which the page has size D = 1 . All request locations are not known in advance; however, they are sequentially presented in an online fashion. We design a 2.75 -competitive online algorithm that improves the current best upper bound for the problem with the unit page size. We also provide a lower bound of 2.732 for our algorithm. It was already known that 2.5 is a lower bound for this problem.

    Programming the BBC Micro is a 12-chapter book that begins with a description of the BBC microcomputer, its peripheral, and faults. Subsequent chapters focus on practice in programming, program development, graphics, words, numbers, sound, bits, bytes, and assembly language. The interfacing, file handling, and detailed description of BBC microcomputer are also shown.

  3. On the convergence of Le Page series in Skohorod space

    CERN Document Server

    Davydov, Youri

    2011-01-01

    We consider the problem of the convergence of the so-called Le Page series in the Skohorod space $\\bbD^d=\\bbD([0,1],\\bbR^d)$ and provide a simple criterion based on the moments of the increments of the random process involved in the series. This provides a simple sufficient condition for the existence of an $\\alpha$-stable distribution on $\\bbD^d$ with given spectral measure.

  4. Broadcast and Aggregation in BBC

    DEFF Research Database (Denmark)

    Hüttel, Hans; Kiilerich Pratas, Nuno

    2015-01-01

    In this paper we introduce a process calculus BBC that has both forms of communication. For both many-to-one and one-to-many communication, it is often a natural assumption that communication is bounded; this reflects two distinct aspects of the limitations of a medium. In the case of broadcast......, the bound limits the number of possible recipients of a message. In the case of collection, the bound limits the number of messages that can be received. For this reason, BBC uses a notion of bounded broadcast and collection. Moreover, the syntax of the calculus introduces an explicit notion of connectivity...

  5. Angular Spacing Control for Segmented Data Pages in Angle-Multiplexed Holographic Memory

    To improve the recording density of angle-multiplexed holographic memory, it is effective to increase the numerical aperture of the lens and to shorten the wavelength of the laser source as well as to increase the multiplexing number. The angular selectivity of a hologram, which determines the multiplexing number, is dependent on the incident angle of not only the reference beam but also the signal beam to the holographic recording medium. The actual signal beam, which is a convergent or divergent beam, is regarded as the sum of plane waves that have different propagation directions, angular selectivities, and optimal angular spacings. In this paper, focusing on the differences in the optimal angular spacing, we proposed a method to control the angular spacing for each segmented data page. We investigated the angular selectivity of a hologram and crosstalk for segmented data pages using numerical simulation. The experimental results showed a practical bit-error rate on the order of 10-3.

    2007-12-01

    Crowding is thought to be one potent limiting factor of reading in peripheral vision. While several studies investigated how crowding between horizontally adjacent letters or words can influence eccentric reading, little attention has been paid to the influence of vertically adjacent lines of text. The goal of this study was to examine the dependence of page mode reading performance (speed and accuracy) on interline spacing. A gaze-contingent visual display was used to simulate a visual central scotoma while normally sighted observers read meaningful French sentences following MNREAD principles. The sensitivity of this new material to low-level factors was confirmed by showing strong effects of perceptual learning, print size and scotoma size on reading performance. In contrast, reading speed was only slightly modulated by interline spacing even for the largest range tested: a 26% gain for a 178% increase in spacing. This modest effect sharply contrasts with the dramatic influence of vertical word spacing found in a recent RSVP study. This discrepancy suggests either that vertical crowding is minimized when reading meaningful sentences, or that the interaction between crowding and other factors such as attention and/or visuo-motor control is dependent on the paradigm used to assess reading speed (page vs. RSVP mode).

    The BBC publishes large amounts of content online, as text, audio and video. As the amount of content grows, we need to make it easy for users to locate items of interest and to draw coherent journeys across them. In this chapter, we describe our use of Semantic Web technologies for achieving this goal. We focus in particular on three BBC Web sites: BBC Programmes, BBC Music and BBC Wildlife Finder, and how those Web sites effectively use the wider Web as their Content Management System.

  15. Gendered spaces, gendered pages: Union women in Civil War nurse narratives.

    Science.gov (United States)

    Telford, Jennifer Casavant; Long, Thomas Lawrence

    2012-12-01

    This interdisciplinary analysis joins literary and culture studies with history using Daphne Spain's theory of gendered spaces. Specifically, we examine the reconfiguration of the spaces of military medical work and of book publishing that produced popular literary representations of those medical spaces. As a social historian of nursing and a scholar of American literature and culture, we argue that the examination of Civil War narratives by or about Northern female nurses surveys a landscape in which women penetrated the masculine spaces of the military hospital and the literary spaces of the wartime narrative. In so doing, these women transformed these spaces into places acknowledging and even relying upon what had been traditionally considered male domains. Like many historiographical papers written about nurses and the impact of their practice over time, this work is relevant to those practicing nursing today, specifically those issues related to professional authority and professional autonomy.

  5. The Culture of the BBC: A Personal Appreciation La culture de la BBC : Une appréciation personnelle

    Directory of Open Access Journals (Sweden)

    Lord Asa Briggs

    2004-01-01

    Full Text Available Cet article entend apporter une vision personnelle et indépendante de l’évolution des valeurs affichées par la BBC depuis sa création en 1922. Les premières années de l’histoire de la BBC ont été influencées par les centres d’intérêt de son fondateur Lord Reith – allégeance à l’Écosse, à la religion presbytérienne, à sa formation d’ingénieur et au souvenir de la Première Guerre mondiale. Par la suite, la BBC n’a plus véhiculé une culture mais des cultures, son monopole sur le discours concernant la culture et la société ayant été remis en question sous l’influence de changements dans la composition de la société dans les années 1960. Dans les années 1980, au moment où se développe la radiodiffusion commerciale, la BBC a résisté à la tentation de considérer son audience comme un marché. La BBC ne peut donc selon Asa Briggs entrer dans les problématiques de l’École de Francfort. Au début du vingt-et-unième siècle, si l’impact de la philosophie de Reith est encore palpable (attachement à la notion de service public, refus du profit comme justification, la hiérarchie des missions de la BBC a changé : alors qu’initialement, la mission de la BBC était régie par une « sainte trinité » où se succédaient dans cet ordre divertissement, éducation et information, cette dernière a maintenant acquis la première place ; l’éducation reçoit une importance nouvelle. En revanche, si l’émission la plus ancienne à la radio britannique était une émission religieuse, la BBC n’affiche plus de mission ni envers la religion, ni envers le sport. La possession de compétences technologiques prime désormais sur l’articulation d’une vision lorsqu’il s’agit de recruter des dirigeants pour cette institution.

The frequency of lexical items was observed to not differ significantly. Two sets of translations were compared to their source texts based on four discursive strategies of hyperbole, polarization, vagueness and euphemism. An independent-samples t-test was conducted to compare the frequency of strategies applied by the two news agencies. Results revealed no significant difference between the two agencies except for the discursive strategy of vagueness.

  17. Elite science and the BBC: a 1950s contest of ownership.

    Science.gov (United States)

    Jones, Allan

    2014-12-01

    In the late 1950s and early 1960s, the elite world of institutional British science attempted to take control of the BBC's management of science broadcasting. Delegations of scientists met BBC managers to propose an increased role for scientists in planning science broadcasts to a degree that threatened to compromise the BBC's authority and autonomy. The culmination was a set of proposals to the Pilkington Committee in 1960, principally from the Royal Society and the British Association for the Advancement of Science, under which a scientist-manager was to be appointed head of a unified science division in the BBC. BBC managers resisted these proposals. The outcome, in 1964, was a compromise giving the scientists little of what they wanted, and proving practically and strategically useful for the BBC. The article frames the story as a contest of jurisdiction between elite science and the BBC, and draws on scholarship relating to the social nature of authority and professions, and to the popularization of science. It shows the fundamentally different beliefs held by the scientists and the BBC about the purpose of science broadcasts and about the nature of the audience. The historical narrative is based on unpublished archive documents, and it contributes to the small but growing body of work on the historical background to the presentation of science in the broadcast media.

    This paper proposed a watermarking algorithm for tamper-proof of web pages. For a web page, it generates a watermark consisting of a sequence of Space and Tab. The watermark is then embedded into the web page after each word and each line. When a watermarked web page is tampered, the extracted watermark can detect and locate the modifications to the web page. Besides, the framework of watermarked Web Server system was given.Compared with traditional digital signature methods, this watermarking method is more transparent in that there is no necessary to detach the watermark before displaying web pages. The experimental results show that the proposed scheme is an effective tool for tamper-proof of web pages.

Nearly 2.5 million posts from over 18 thousand users were investigated. Scale-free distributions were observed for activity in individual discussion threads as well as for overall activity. The number of unique users in a thread normalized by the thread length decays with thread length, suggesting that thread life is sustained by mutual discussions rather than by independent comments. Automatic sentiment analysis shows that most posts contain negative emotions and the most active users in individual threads express predominantly negative sentiments. It follows that the average emotion of longer threads is more negative and that threads can be sustained by negative comments. An agent-based computer simulation model has been used to reproduce several essential characteristics of the analyzed system. The model stresses the role of discussions between users, especially emotionally laden quarrels between supporters of opposite opinions, and represents many observed statistics of the forum.

  8. Cuckoo Hashing with Pages

    CERN Document Server

    Dietzfelbinger, Martin; Rink, Michael

    2011-01-01

    Although cuckoo hashing has significant applications in both theoretical and practical settings, a relevant downside is that it requires lookups to multiple locations. In many settings, where lookups are expensive, cuckoo hashing becomes a less compelling alternative. One such standard setting is when memory is arranged in large pages, and a major cost is the number of page accesses. We propose the study of cuckoo hashing with pages, advocating approaches where each key has several possible locations, or cells, on a single page, and additional choices on a second backup page. We show experimentally that with k cell choices on one page and a single backup cell choice, one can achieve nearly the same loads as when each key has k+1 random cells to choose from, with most lookups requiring just one page access, even when keys are placed online using a simple algorithm. While our results are currently experimental, they suggest several interesting new open theoretical questions for cuckoo hashing with pages.

    The paper deals with constitutive modelling of highly anisotropic sheet metals. It presents FEM based earing predictions in cup drawing simulation of highly anisotropic aluminium alloys where more than four ears occur. For that purpose the BBC2008 yield criterion, which is a plane-stress yield criterion formulated in the form of a finite series, is used. Thus defined criterion can be expanded to retain more or less terms, depending on the amount of given experimental data. In order to use the model in sheet metal forming simulations we have implemented it in a general purpose finite element code ABAQUS/Explicit via VUMAT subroutine, considering alternatively eight or sixteen parameters (8p and 16p version). For the integration of the constitutive model the explicit NICE (Next Increment Corrects Error) integration scheme has been used. Due to the scheme effectiveness the CPU time consumption for a simulation is comparable to the time consumption of built-in constitutive models. Two aluminium alloys, namely AA5042-H2 and AA2090-T3, have been used for a validation of the model. For both alloys the parameters of the BBC2008 model have been identified with a developed numerical procedure, based on a minimization of the developed cost function. For both materials, the predictions of the BBC2008 model prove to be in very good agreement with the experimental results. The flexibility and the accuracy of the model together with the identification and integration procedure guarantee the applicability of the BBC2008 yield criterion in industrial applications.

  10. J.G. Crowther's War: Institutional strife at the BBC and British Council.

    Science.gov (United States)

    Jones, Allan

    2016-06-01

    Science writer, historian and administrator J.G. Crowther (1899-1983) had an uneasy relationship with the BBC during the 1920s and 1930s, and was regarded with suspicion by the British security services because of his left politics. Nevertheless the Second World War saw him working for 'establishment' institutions. He was closely associated with the BBC's Overseas Service and employed by the British Council's Science Committee. Both organizations found Crowther useful because of his wide, international knowledge of science and scientists. Crowther's political views, and his international aspirations for the British Council's Science Committee, increasingly embroiled him in an institutional conflict with the Royal Society and with its president, Sir Henry Dale, who was also chairman of the British Council's Science Committee. The conflict centred on the management of international scientific relations, a matter close Crowther's heart, and to Dale's. Dale considered that the formal conduct of international scientific relations was the Royal Society's business rather than the British Council's. Crowther disagreed, and eventually resigned from the British Council Science Committee in 1946. The article expands knowledge of Crowther by drawing on archival documents to elucidate a side of his career that is only lightly touched on in his memoirs. It shows that 'Crowther's war' was also an institutional war between the Science Committee of the British Council and the Royal Society. Crowther's unhappy experience of interference by the Royal Society plausibly accounts for a retreat from his pre-war view that institutional science should plan and manage BBC science broadcasts.

  12. Multiplex PageRank

    CERN Document Server

    Halu, Arda; Pansaraza, Pietro; Bianconi, Ginestra

    2013-01-01

    Many complex systems can be described as multiplex networks in which the same nodes can interact with one another in different layers, thus forming a set of interacting and co-evolving networks. Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the in...

    in hand to allow for a more limited production of a paper version of the Annals for RCS fellows and members who continue to elect to receive their Annals in the traditional format. Medical colleges around the world are currently undergoing similar deliberations and for some a digital version may represent the only opportunity to maintain editorial independence – unhindered by the implications of a commercial publishing partner. It is however hoped that for the vast majority of fellows and members, the new and enhanced digital platform will offer significant advantages such that the digital version becomes the de facto medium of choice. Matt Whitaker and the team at the Annals should be congratulated for their sterling efforts in making this transition. The new site, now live at http://publishing.rcseng.ac.uk, will enhance the experience of finding, accessing, reading, citing, sharing and saving articles from the Annals, Bulletin and FDJ. Sign-on will be much easier; page load times quicker and the search engine more powerful and intuitive. The new platform boasts improved functionality, full in-page article text and multi-media, citation tracking, reference generators and advanced social media integration. We are simultaneously launching a new video library where we will be hosting our technical videos. It will, I am certain, become a huge resource for our surgical fraternity. Our new platform will be followed later this year by the inevitable and ubiquitous app, which will allow readers to download issues of the Annals and read them offline and at leisure on whatever their tablet of choice might be. It is my belief that these and forthcoming changes herald the transformation of the Annals into a truly modern journal with all the digital services that authors and readers now rightly expect from their RCS publication.

    2016-11-01

    Full Text Available Clerical masculinities, much like their lay/secular counterparts, often appear unchang¬ing because they are the products of naturalization processes. Clerical masculinities, however, are far from stable, for they live and breathe the dynamics of both their socio-religious context and their secular “others”. The BBC sitcom Rev. (BBC2, UK 2010–2014 is a refreshing take on the everyday life and problems of a vicar in the Church of England trying to avoid stereotypes that often come with clerical roles. Rev. (2010–2014 can be interpreted as an attempt to explore the negotiation processes of masculinity within an institution that is involved in the “production” of religion and gender roles. It shows that being a man in an institutional setting is as much a perfor¬mance as it is a more or less successful negotiation of other people’s expectations and one’s own worldview. In particular, the main male clerical characters in Rev. (2010– 2014 inhabit a position of power but all have their flaws. They can best be understood as losers whose clash with masculine systems renders them more human.

  7. Distributed paging for general networks

    Distributed paging deals with the dynamic allocation of copies of files in a distributed network as to minimize the total communication cost over a sequence of read and write requests. Most previous work deals with the file allocation problem where infinite nodal memory capacity is assumed. In contrast the distributed paging problem makes the more realistic assumption that nodal memory capacity is limited. Former work on distributed paging deals with the problem only in the case of a uniform network topology. This paper gives the first distributed paging algorithm for general networks. The algorithm is competitive in storage and communication. The competitive ratios are poly-logarithmic in the total number of network nodes and the diameter of the network.

    2012-01-01

    We build up a directed network tracing links from a given integer to its divisors and analyze the properties of the Google matrix of this network. The PageRank vector of this matrix is computed numerically and it is shown that its probability is inversely proportional to the PageRank index thus being similar to the Zipf law and the dependence established for the World Wide Web. The spectrum of the Google matrix of integers is characterized by a large gap and a relatively small number of nonzero eigenvalues. A simple semi-analytical expression for the PageRank of integers is derived that allows to find this vector for matrices of billion size. This network provides a new PageRank order of integers.

    Full Text Available Online journalism is fast becoming a central source of news worldwide. Yet all too often the perception of online is that it’s rough and ready, and what’s worse, that audiences don’t care. This paper argues that the predominantly authored form that we know as video journalism owes more to the cinematic aesthetics of documentary and cinema than traditional news, and that the growth of online digital literacy has had a profound impact on audiences’ expectations of production quality.  The author’s recent work for BBC News are used as case studies to reveal how VJs are able to implement cinematic approaches at both a narrative and aesthetic level

    Full Text Available The present study focuses on expressions of emotion in online news and blogs and the way in which they contribute to shaping the co-construction of information about an issue of public concern (more specifically the environmental issue and the discoursal identities of participant communities. The theoretical framework of analysis is based on recent developments in discourse studies and appraisal theory on language about emotions. The corpus of data (BBC online articles and readers’ comments have been analysed adapting the classification system of affect-types elaborated by Bednarek (2008. However limited, the data offer interesting and unexpected insights into participation to news construction and user-generated content: the way in which news and information are reported (the mediated ‘narrative’ elicits more language about emotion and concern than the central issue at stake (the environmental problem.

  12. ONTOPARK: ONTOLOGY BASED PAGE RANKING FRAMEWORK USING RESOURCE DESCRIPTION FRAMEWORK

    Directory of Open Access Journals (Sweden)

    S. Yasodha

    2014-01-01

    Full Text Available Traditional search engines like Google and Yahoo fail to rank the relevant information for users’ query. This is because such search engines rely on keywords for searching and they fail to consider the semantics of the query. More sophisticated methods that do provide the relevant information for the query is the need of the time. The Semantic Web that stores metadata as ontology could be used to solve this problem. The major drawback of the PageRank algorithm of Google is that ranking is based not only on the page ranks produced but also on the number of hits to the Web page. This paved way for illegitimate means of boosting page ranks. As a result, Web pages whose page rank is zero are also ranked in top-order. This drawback of PageRank algorithm motivated us to contribute to the Web community to provide semantic search results. So we propose ONTOPARK, an ontology based framework for ranking Web pages. The proposed framework combines the Vector Space Model of Information Retrieval with Ontology. The framework constructs semantically annotated Resource Description Framework (RDF files which form the RDF knowledgebase for each query. The proposed framework has been evaluated by two measures, precision and recall. The proposed framework improves the precision of both single-word and multi-word queries which infer that replacing Web database by semantic knowledgebase will definitely improve the quality of search. The surfing time of the surfers will also be minimized.

    Most Web page classification models typically apply the bag of words (BOW) model to represent the feature space. The original BOW representation, however, is unable to recognize semantic relationships between terms. One possible solution is to apply the topic model approach based on the Latent Dirichlet Allocation algorithm to cluster the term features into a set of latent topics. Terms assigned into the same topic are semantically related. In this paper, we propose a novel hierarchical class...

    Directory of Open Access Journals (Sweden)

    Daniel Ruff

    2009-10-01

    Full Text Available This article argues that the relationship between Margaret Thatcher and her governments of the 1980s on the one hand, and the BBC on the other, differed from those of an ‘arm’s length’ regulator which had existed since the creation of the BBC through successive Conservative and Labour governments until 1979, in which ministers would not intervene in BBC policy or programming. Ministers and party members instituted a concerted attempt to intimidate the BBC, most especially its news and current affairs programmes, whenever the latter did not report national politics and international events to the government’s liking. Proposed neo-liberal reforms to the system of funding the Corporation and negotiations for regular increases in the value of the licence fee were similarly opportunities to exert pressure on the BBC and to call into question its public service remit. Finally, royal prerogative and royal patronage were used to manipulate the political colour of the Board of Governors and thus, indirectly, the management of the BBC.

    为解决PageRank算法存在的"主题漂移"问题,本文提出一种融合VSM(向量空间模型)技术的改进方法.首先根据网页的链接结构计算PageRank值,然后建立网页的内容特征向量空间,计算主题内容相似度,最后将这两个值按一定的权重系数进行融合计算,产生新的PageRank值.经过对比实验证明,改进后的PageRank算法减少了无关网页的数量,为搜索引擎提供了更好的排序结果.%In order to solve the "Topic Drift" problem of PageRank algorithm, this paper proposes an improved method combined with VSM( vector space model) technique. First, it computes PageRank value by hyperlink structure of Web page, then builds vector space model of Web page content and computes topic content similarity. Finally it sums up new PageRank value according these two values by certain weight coefficient. Contrast experiments show that improved PageRank algorithm reduces the quantity of irrelevant Web page and provides better sorting results for search engine.

    This paper presents a new method that eliminates noise in Web page classification. It first describes the presentation of a Web page based on HTML tags. Then through a novel distance formula, it eliminates the noise in similarity measure. After carefully analyzing Web pages, we design an algorithm that can distinguish related hyperlinks from noisy ones.We can utilize non-noisy hyperlinks to improve the performance of Web page classification (the CAWN algorithm). For any page, wecan classify it through the text and category of neighbor pages related to the page. The experimental results show that our approach improved classification accuracy.

    A market survey was conducted regarding the commercialization potential and key market factors relevant to a tactile paging system for deaf-blind people. The purpose of the tactile paging system is to communicate to the deaf-blind people in an institutional environment. The system consists of a main console and individual satellite wrist units. The console emits three signals by telemetry to the wrist com (receiving unit) which will measure approximately 2 x 4 x 3/4 inches and will be fastened to the wrist by a strap. The three vibration signals are fire alarm, time period indication, and a third signal which will alert the wearer of the wrist com to the fact that the pin on the top of the wrist is emitting a morse coded message. The Morse code message can be felt and recognized with the finger.

    Iacovacci, Jacopo; Arenas, Alex; Bianconi, Ginestra

    2016-01-01

    Recently it has been recognized that many complex social, technological and biological networks have a multilayer nature and can be described by multiplex networks. Multiplex networks are formed by a set of nodes connected by links having different connotations forming the different layers of the multiplex. Characterizing the centrality of the nodes in a multiplex network is a challenging task since the centrality of the node naturally depends on the importance associated to links of a certain type. Here we propose to assign to each node of a multiplex network a centrality called Functional Multiplex PageRank that is a function of the weights given to every different pattern of connections (multilinks) existent in the multiplex network between any two nodes. Since multilinks distinguish all the possible ways in which the links in different layers can overlap, the Functional Multiplex PageRank can describe important non-linear effects when large relevance or small relevance is assigned to multilinks with overl...

  9. An Optimization Model for Product Placement on Product Listing Pages

    Directory of Open Access Journals (Sweden)

    Yan-Kwang Chen

    2014-01-01

    Full Text Available The design of product listing pages is a key component of Website design because it has significant influence on the sales volume on a Website. This study focuses on product placement in designing product listing pages. Product placement concerns how venders of online stores place their products over the product listing pages for maximization of profit. This problem is very similar to the offline shelf management problem. Since product information sources on a Web page are typically communicated through the text and image, visual stimuli such as color, shape, size, and spatial arrangement often have an effect on the visual attention of online shoppers and, in turn, influence their eventual purchase decisions. In view of the above, this study synthesizes the visual attention literature and theory of shelf-space allocation to develop a mathematical programming model with genetic algorithms for finding optimal solutions to the focused issue. The validity of the model is illustrated with example problems.

Here we apply the Functional Page Rank to the multiplex airport networks, to the neuronal network of the nematode C. elegans, and to social collaboration and citation networks between scientists. This analysis reveals important differences existing between the most central nodes of these networks, and the correlations between their so-called pattern to success.

    Using perturbative quantum chromodynamics and quark-diquark model of baryons, we have obtained an analytical fragmentation function which describes {omega}{sub bbc} and {omega}{sub bcc} baryons in b and c quarks fragmentation. The universal fragmentation probabilities, the average fragmentation parameters and the production cross sections resulting from this function are in a very good agreement with those obtained using a full perturbative regime. We conclude that the quark-diquark model of baryons works well when a scalar heavy diquark is considered in a heavy quark fragmentation into a triply heavy baryon.

    2012-01-01

    The evaluation of a web page with respect to a query is a vital task in the web information retrieval domain. This paper proposes the evaluation of a web page as a bottom-up process from the segment level to the page level. A model for evaluating the relevancy is proposed incorporating six different dimensions. An algorithm for evaluating the segments of a web page, using the above mentioned six dimensions is proposed. The benefits of fine-granining the evaluation process to the segment level instead of the page level are explored. The proposed model can be incorporated for various tasks like web page personalization, result re-ranking, mobile device page rendering etc.

    Full Text Available The traditional search engines available over the internet are dynamic in searching the relevant content over the web. The search engine has got some constraints like getting the data asked from a varied source, where the data relevancy is exceptional. The web crawlers are designed only to more towards a specific path of the web and are restricted in moving towards a different path as they are secured or at times restricted due to the apprehension of threats. It is possible to design a web crawler that will have the capability of penetrating through the paths of the web, not reachable by the traditional web crawlers, in order to get a better solution in terms of data, time and relevancy for the given search query. The paper makes use of a newer parser and indexer for coming out with a novel idea of web crawler and a framework to support it. The proposed web crawler is designed to attend Hyper Text Transfer Protocol Secure (HTTPS based websites and web pages that needs authentication to view and index. User has to fill a search form and his/her creditionals will be used by the web crawler to attend secure web server for authentication. Once it is indexed the secure web server will be inside the web crawler’s accessible zone

    Full Text Available Phishing is process of steeling valuable information such as ATM pins, Credit card details over internet. Where the attacker creates mimicked web pages from the legitimate web pages to fool users. In this paper, we propose an effective anti-phishing solution, by combining image based visual similarity based approach to detect plagiarized web pages. We used effective algorithms for our detection mechanism, speeded up Robust Features (SURF algorithm in order to generate signature based on extracting stable key points from the screen shot of the web page. When a legitimate web page is registered with our system, this algorithm applied on that web page in order to generate signatures, and these signatures are stored in the database for our trained system. When there is a suspected web page, this algorithm is applied to generate both the signatures of the suspected page and is verified against our database of corresponding legitimate web pages. Our results verified that our proposed system is very effective to detect the mimicked web pages with minimal false positives

    Kato, Yoshikiyo; Kawahara, Daisuke; Inui, Kentaro; Kurohashi, Sadao; Shibata, Tomohide

    The source of information is one of the crucial elements when judging the credibility of the information. On the current Web, however, the information about the source is not readily available to the users. In this paper, we formulate the problem of identifying the information source as the problem of identifying the information sender configuration (ISC) of a Web page. An information sender of a Web page is an entity which is involved in the publication of the information on the page. An information sender configuration of a Web page describes the information senders of the page and the relationship among them. Information sender identification is a sub-problem of identifying ISC, and we present a method for extracting information senders from Web pages, along with its evaluation. ISC provides a basis for deeper analysis of information on the Web.

    2010-01-01

    Web page categorization is one of the challenging tasks in the world of ever increasing web technologies. There are many ways of categorization of web pages based on different approach and features. This paper proposes a new dimension in the way of categorization of web pages using artificial neural network (ANN) through extracting the features automatically. Here eight major categories of web pages have been selected for categorization; these are business & economy, education, government, entertainment, sports, news & media, job search, and science. The whole process of the proposed system is done in three successive stages. In the first stage, the features are automatically extracted through analyzing the source of the web pages. The second stage includes fixing the input values of the neural network; all the values remain between 0 and 1. The variations in those values affect the output. Finally the third stage determines the class of a certain web page out of eight predefined classes. This stage i...

This paper presents a new 3D page-turning simulation approach, which employs piecewise time-dependent cylindrical surfaces to describe the turning page and constructs smooth transition method between time-dependent cylinders. The page-turning animation is produced by sequentially mapping the turning page into the cylinders with different radii and positions. Compared to the previous approaches, our method is able to imitate various effects efficiently and obtains more natural animation of turning page.

    The purpose of this study was to assess the websites of American Association of Medical Colleges (AAMC)-member medical schools for the presence of library links. Sixty-one percent (n = 92) of home pages of the 150 member schools of the AAMC contain library links. For the 58 home pages not offering such links, 50 provided a pathway of two or three clicks to a library link. The absence of library links on 39% of AAMC medical school home pages indicates that the designers of those pages did not consider the library to be a primary destination for their visitors.

    Full Text Available Algunas voces cuestionan la permanencia de las televisiones públicas en el nuevo entorno digital, caracterizado por una mayor presencia de Internet, más competidores y la fragmentación de la audiencia. Sin embargo, hay otros que creen que deberían actuar como una fuerza motriz en el proceso de convergencia e incluso que los nuevos medios representan una posibilidad de redefinir la misión de las televisiones públicas. El reto actual de las corporaciones públicas es proporcionar los contenidos a través del mayor número de soportes posibles, no solo a través de la televisión, sino también a través de Internet y dispositivos móviles. Un rasgo de la BBC es haberse adaptado siempre a los cambios del mercado y muchas de sus soluciones han sido transferidas a otras empresas de comunicación tanto públicas como privadas de todo el mundo. El objetivo de este artículo es mostrar cómo la BBC es uno de los modelos en los que las empresas televisivas se han fijado para transformar sus servicios digitales a fin de mantener su existencia en el mercado, y conocer cuál ha sido su influencia en la televisión pública española RTVE. La metodología empleada radica en el análisis de los documentos internos y externos de las compañías y entrevistas realizadas a los responsables de los servicios digitales de RTVE. Las conclusiones apuntan a destacar que estas compañías han adaptado sus actividades a las nuevas tecnologías y han desarrollado servicios interactivos como refuerzo de su misión de servicio público.Some authors question the existence of public television companies in the new environment of digitalization, Internet proliferation, growing competition and audience segmentation.

    Methods for ranking the importance of nodes in a network have a rich history in machine learning and across domains that analyze structured data. Recent work has evaluated these methods though the seed set expansion problem: given a subset $S$ of nodes from a community of interest in an underlying graph, can we reliably identify the rest of the community? We start from the observation that the most widely used techniques for this problem, personalized PageRank and heat kernel methods, operate in the space of landing probabilities of a random walk rooted at the seed set, ranking nodes according to weighted sums of landing probabilities of different length walks. Both schemes, however, lack an a priori relationship to the seed set objective. In this work we develop a principled framework for evaluating ranking methods by studying seed set expansion applied to the stochastic block model. We derive the optimal gradient for separating the landing probabilities of two classes in a stochastic block model, and find, ...

    2015-01-01

    Following recent developments in quantum PageRanking, we present a comparative analysis of discrete-time and continuous-time quantum-walk-based PageRank algorithms. For the discrete-time case, we introduce an alternative PageRank measure based on the maximum probabilities achieved by the walker on the nodes. We demonstrate that the required time of evolution does not scale significantly with increasing network size. We affirm that all three quantum PageRank measures considered here distinguish clearly between outerplanar hierarchical, scale-free, and Erd\\"os-R\\'enyi network types. Relative to classical PageRank and to different extents, the quantum measures better highlight secondary hubs and resolve ranking degeneracy among peripheral nodes for the networks we studied in this paper.

    Two popular webpage ranking algorithms are HITS and PageRank. HITS emphasizes mutual reinforcement between authority and hub webpages, while PageRank emphasizes hyperlink weight normalization and web surfing based on random walk models. We systematically generalize/combine these concepts into a unified framework. The ranking framework contains a large algorithm space; HITS and PageRank are two extreme ends in this space. We study several normalized ranking algorithms which are intermediate between HITS and PageRank, and obtain closed-form solutions. We show that, to first order approximation, all ranking algorithms in this framework, including PageRank and HITS, lead to same ranking which is highly correlated with ranking by indegree. These results support the notion that in web resource ranking indegree and outdegree are of fundamental importance. Rankings of webgraphs of different sizes and queries are presented to illustrate our analysis.

    Full Text Available Choosing the right keywords is relatively easy, whereas getting a high PageRank is more complicated. The index Page Rank is what defines the position in the result pages of search engines (for Google of course, but the other engines are now using more or less the same kind of algorithm. It is therefore very important to understand how this type of algorithm functions to hope to appear on the first page of results (the only page read in 95 % of cases or at least be among the first. We propose in this paper to clarify the operation of this algorithm using a matrix method and a JavaScript program enabling to experience this type of analysis. It is of course a simplified version, but it can add value to the website and achieve a high ranking in the search results and reach a larger customer base. The interest is to disclose an algorithm to calculate the relevance of each page. This is in fact a mathematical algorithm based on a web graph. This graph is formed of all the web pages that are modeled by nodes, and hyperlinks that are modeled by arcs.

    Full Text Available Due to the limited main memory resource of consumer electronics equipped with NAND flash memory as storage device, an efficient page replacement algorithm called FAPRA is proposed for NAND flash memory in the light of its inherent characteristics. FAPRA introduces an efficient victim page selection scheme taking into account the benefit-to-cost ratio for evicting each victim page candidate and the combined recency and frequency value, as well as the erase count of the block to which each page belongs. Since the dirty victim page often contains clean data that exist in both the main memory and the NAND flash memory based storage device, FAPRA only writes the dirty data within the victim page back to the NAND flash memory based storage device in order to reduce the redundant write operations. We conduct a series of trace-driven simulations and experimental results show that our proposed FAPRA algorithm outperforms the state-of-the-art algorithms in terms of page hit ratio, the number of write operations, runtime, and the degree of wear leveling.

    This paper describes our solution for WSDM Cup 2016. Ranking the query independent importance of scholarly articles is a critical and challenging task, due to the heterogeneity and dynamism of entities involved. Our approach is called Ensemble enabled Weighted PageRank (EWPR). To do this, we first propose Time-Weighted PageRank that extends PageRank by introducing a time decaying factor. We then develop an ensemble method to assemble the authorities of the heterogeneous entities involved in scholarly articles. We finally propose to use external data sources to further improve the ranking accuracy. Our experimental study shows that our EWPR is a good choice for ranking scholarly articles.

    2008-03-01

    Full Text Available As the Internet provides millions of web pages for each and every search term, getting interesting and required results quickly from the Web becomes very difficult. Automatic classification of web pages into relevant categories is the current research topic which helps the search engine to get relevant results. As the web pages contain many irrelevant, infrequent and stop words that reduce the performance of the classifier, extracting or selecting representative features from the web page is an essential pre-processing step. The goal of this paper is to find minimum number of highly qualitative features by integrating feature selection techniques. We conducted experiments with various numbers of features selected by different feature selection algorithms on a well defined initial set of features and show that cfssubset evaluator combined with term frequency method gives minimal qualitative features enough to attain considerable classification accuracy.

    The PageRank algorithm enables to rank the nodes of a network through a specific eigenvector of the Google matrix, using a damping parameter $\\alpha \\in ]0,1[$. Using extensive numerical simulations of large web networks, we determine numerically and analytically the universal features of PageRank vector at its emergence when $\\alpha \\rightarrow 1$. The whole network can be divided into a core part and a group of invariant subspaces. For $ \\alpha \\rightarrow 1$ the PageRank converges to a universal power law distribution on the invariant subspaces whose size distribution also follows a universal power law. The convergence of PageRank at $ \\alpha \\rightarrow 1$ is controlled by eigenvalues of the core part of the Google matrix which are exponentially close to unity leading to large relaxation times as for example in spin glasses.

    Recently, web pages for mobile devices are widely spread on the Internet and a lot of people can access web pages through search engines by mobile devices as well as personal computers. A summary of a retrieved web page is important because the people judge whether or not the page would be relevant to their information need according to the summary. In particular, the summary must be not only compact but also grammatical and meaningful when the users retrieve information using a mobile phone with a small screen. Most search engines seem to produce a snippet based on the keyword-in-context (KWIC) method. However, this simple method could not generate a refined summary suitable for mobile phones because of low grammaticality and content overlap with the page title. We propose a more suitable method to generate a snippet for mobile devices using sentence extraction and sentence compression methods. First, sentences are biased based on whether they include the query terms from the users or words that are relevant to the queries, as well as whether they do not overlap with the page title based on maximal marginal relevance (MMR). Second, the selected sentences are compressed based on their phrase coverage, which is measured by the scores of words, and their phrase connection probability measured based on the language model, according to the dependency structure converted from the sentence. The experimental results reveal the proposed method outperformed the KWIC method in terms of relevance judgment, grammaticality, non-redundancy and content coverage.

    Changes to the printing service were announced in CERN Bulletin No. 37-38/2006. In the new infrastructure, the printing of the banner page has been disabled in order to reduce paper consumption. Statistics show that the average print job size is small and the paper savings by not printing the banner page could be up to 20 %. When each printer is moved onto the new infrastructure banner page printing will be disabled. In the case of corridor printers which are shared by several users, the Helpdesk can re-enable banner page printing upon request. We hope ultimately to arrive at a situation where banner page printing is enabled on fewer than 10% of printers registered on the network. You can still print banner pages on printers where it has been centrally disabled by using Linux. Simply add it to your print job on the client side by adding the -o job-sheets option to your lpr command.

    We use the methods of quantum chaos and Random Matrix Theory for analysis of statistical fluctuations of PageRank probabilities in directed networks. In this approach the effective energy levels are given by a logarithm of PageRank probability at a given node. After the standard energy level unfolding procedure we establish that the nearest spacing distribution of PageRank probabilities is described by the Poisson law typical for integrable quantum systems. Our studies are done for the Twitter network and three networks of Wikipedia editions in English, French and German. We argue that due to absence of level repulsion the PageRank order of nearby nodes can be easily interchanged. The obtained Poisson law implies that the nearby PageRank probabilities fluctuate as random independent variables.

    CERN Beams Department maintains a website with various tools for the Operations Group, with one of them being specific for the Proton Irradiation Facility (IRRAD). The IRRAD team use the tool to follow up and optimize the operation of the facility. The original version of the tool was difficult to maintain and adding new features to the page was challenging. Thus this summer student project is aimed to upgrade the web page by rewriting the web page with maintainability and flexibility in mind. The new application uses a server--client architecture with a REST API on the back end which is used by the front end to request data for visualization. PHP is used on the back end to implement the API's and Swagger is used to document them. Vue, Semantic UI, Webpack, Node and ECMAScript 5 is used on the fronted to visualize and administrate the data. The result is a new IRRAD operations web application with extended functionality, improved structure and an improved user interface. It includes a new Status Panel page th...

    Full Text Available Data mining is extracting and automatic discovering the web based information has been used as web mining. It is one of the most universal and a dominant application on the Internet and it becomes increasing in size and search tools that combine the results of multiple search engines are becoming more valuable. But, almost none of these studies deals with genetic relation algorithm (GRA, where GRA is one of the evolutionary methods with graph structure. GRA was designed to both increase the effectiveness of search engine and improve their efficiency. GRA considers the correlation coefficient between stock brands as strength, which indicates the relation between nodes in each individual of GRA. The reduced number of hyperlinks provided by GRA in the final generation consists of only the most similar hyperlinks with respect to the query. But, the end user’s not satisfied fully. To improve the satisfaction of user by using Page rank algorithm to measure the importance of a page and to prioritize pages returned from a GRA. It will reduce the user’s searching time. PageRank algorithm works to allocate rank for filtered links based on number of keyword occurred in the content.

  3. Efficient Web Change Monitoring with Page Digest

    2004-02-20

    The Internet and the World Wide Web have enabled a publishing explosion of useful online information, which has produced the unfortunate side effect of information overload: it is increasingly difficult for individuals to keep abreast of fresh information. In this paper we describe an approach for building a system for efficiently monitoring changes to Web documents. This paper has three main contributions. First, we present a coherent framework that captures different characteristics of Web documents. The system uses the Page Digest encoding to provide a comprehensive monitoring system for content, structure, and other interesting properties of Web documents. Second, the Page Digest encoding enables improved performance for individual page monitors through mechanisms such as short-circuit evaluation, linear time algorithms for document and structure similarity, and data size reduction. Finally, we develop a collection of sentinel grouping techniques based on the Page Digest encoding to reduce redundant processing in large-scale monitoring systems by grouping similar monitoring requests together. We examine how effective these techniques are over a wide range of parameters and have seen an order of magnitude speed up over existing Web-based information monitoring systems.

Despite the producers' proclamation that Holmes is above sex, much less gay sex, the show is ripe with a queer subtext that viewers have recognized and reclaimed as their own. Several scholars have examined Sherlock's appeal to these viewers, but their focus has primarily been on the ways these readings conflict or intersect with how the show and its producers understand him. This article calls for a reading that conceives of a queerness outside of the homosexual domestic. Using José Escobar Muñoz's theory of disidentification, I argue that we should explore readings of the show that do not demand validation of queerness through normative relationships and behaviors. Instead, Sherlock's illegibility allows him to exist in a queer space, outside both essentialist and constructivist ideas of who and what people can be.

    The mycorrhiza helper Pseudomonas fluorescens BBc6R8 promotes the presymbiotic survival and growth of the ectomycorrhizal fungus Laccaria bicolor S238N in the soil. An in vitro fungal-bacterial confrontation bioassay mimicking the promoting effects of the bacteria on fungal growth was set up to analyse the fungal morphological and transcriptional changes induced by the helper bacteria at three successive stages of the interaction. The specificity of the P. fluorescens BBc6R8 effect was assessed in comparison with six other rhizobacterial strains possessing mycorrhiza helper or pathogen antagonistic abilities. The helper BBc6R8 strain was the only strain to induce increases in the radial growth of the colony, hyphal apex density and branching angle. These morphological modifications were coupled with pleiotropic alterations of the fungal transcriptome, which varied throughout the interaction. Early stage-responsive genes were presumably involved in recognition processes and transcription regulation, while late stage-responsive genes encoded proteins of primary metabolism. Some of the responsive genes were partly specific to the interaction with P. fluorescens BBc6R8, whereas others were mutually regulated by different rhizobacteria. The results highlight the fact that the helper BBc6R8 strain has a specific priming effect on growth, morphology and gene expression of its fungal associate L. bicolor S238N.

    The LHCb is one of the main detectors of Large Hadron Collider, where physicists and scientists work together on high precision measurements of matter-antimatter asymmetries and searches for rare and forbidden decays, with the aim of discovering new and unexpected forces. The work does not only consist of analyzing data collected from experiments but also in publishing the results of those analyses. The LHCb publications are gathered on LHCb publications page to maximize their availability to both LHCb members and to the high energy community. In this project a new database system was implemented for LHCb publications page. This will help to improve access to research papers for scientists and better integration with current CERN library website and others.

However, even though people have their favourite sites, and their favourite search engines, they often seem to miss that bit of information. This could very well be because it is hiding on a small, unpopular, enthusiast's Personal Home Page. The author believes that there is more information on the Web than that which one will find on the major, "commercial-style" sites. Hence, this paper looks at the possibility of using Personal Home Pages (PHP as an information resource, not only for the academic, but the web-surfing world in general.

    Introducing clinical staff education, along with new policies and procedures, to over 50 different clinical sites can be a challenge. As any staff educator will confess, getting people to attend an educational inservice session can be difficult. Clinical staff request training, but no one has time to attend training sessions. Putting the training along with the policies and other information into "neat" concise packages via the computer and over the company's intranet was the way to go. However, how do you bring the clinics online when some of the clinical staff may still be reluctant to turn on their computers for anything other than to gather laboratory results? Developing an easy, fun, and accessible Web page was the answer. This article outlines the development of the first training Web page at the University of Wisconsin Medical Foundation, Madison, WI.

    Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines.

  20. Model for Predicting End User Web Page Response Time

    Nagarajan, Sathya Narayanan

    2012-01-01

    Perceived responsiveness of a web page is one of the most important and least understood metrics of web page design, and is critical for attracting and maintaining a large audience. Web pages can be designed to meet performance SLAs early in the product lifecycle if there is a way to predict the apparent responsiveness of a particular page layout. Response time of a web page is largely influenced by page layout and various network characteristics. Since the network characteristics vary widely from country to country, accurately modeling and predicting the perceived responsiveness of a web page from the end user's perspective has traditionally proven very difficult. We propose a model for predicting end user web page response time based on web page, network, browser download and browser rendering characteristics. We start by understanding the key parameters that affect perceived response time. We then model each of these parameters individually using experimental tests and statistical techniques. Finally, we d...

    Full Text Available With the explosive growth of information sources available on the World Wide Web, it has become increasingly necessary for user’s to utilize automated tools in order to find, extract, filter and evaluate the desired information and resources. Web structure mining and content mining plays an effective role in this approach. There are two Ranking algorithms PageRank and Weighted PageRank. PageRank is a commonly used algorithm in Web Structure Mining. Weighted Page Rank also takes the importance of the inlinks and outlinks of the pages but the rank score to all links is not equally distributed. i.e. unequal distribution is performed. In this paper we proposed a new algorithm, Weighted Page Content Rank (WPCRbased on web content mining and structure mining that shows the relevancy of the pages to a given query is better determined, as compared to the existing PageRank and Weighted PageRank algorithms.

  2. Exploiting link structure for web page genre identification

    KAUST Repository

    Zhu, Jia

    2015-07-07

    As the World Wide Web develops at an unprecedented pace, identifying web page genre has recently attracted increasing attention because of its importance in web search. A common approach for identifying genre is to use textual features that can be extracted directly from a web page, that is, On-Page features. The extracted features are subsequently inputted into a machine learning algorithm that will perform classification. However, these approaches may be ineffective when the web page contains limited textual information (e.g., the page is full of images). In this study, we address genre identification of web pages under the aforementioned situation. We propose a framework that uses On-Page features while simultaneously considering information in neighboring pages, that is, the pages that are connected to the original page by backward and forward links. We first introduce a graph-based model called GenreSim, which selects an appropriate set of neighboring pages. We then construct a multiple classifier combination module that utilizes information from the selected neighboring pages and On-Page features to improve performance in genre identification. Experiments are conducted on well-known corpora, and favorable results indicate that our proposed framework is effective, particularly in identifying web pages with limited textual information. © 2015 The Author(s)

During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA.

    Full Text Available In this paper we use machine learning algorithms like SVM, KNN and GIS to perform a behaviorcomparison on the web pages classifications problem, from the experiment we see in the SVM with smallnumber of negative documents to build the centroids has the smallest storage requirement and the least online test computation cost. But almost all GIS with different number of nearest neighbors have an evenhigher storage requirement and on line test computation cost than KNN. This suggests that some futurework should be done to try to reduce the storage requirement and on list test cost of GIS.

    Full Text Available This paper examines a five-year initiative by the UK's public service broadcaster, the BBC, to reinvigorate civic engagement at a time of declining public participation in politics. The Action Network project, originally called iCan, ran from 2003 to 2008 and was one of the most high profile and ambitious attempts by a public service broadcaster to foster eParticipation through an online civic commons. This study analyzes Action Network within the context of conceptualizations of the Internet as a networked, distributed and participatory environment and the shift towards what scholars describe as a networked public sphere. It suggests that the project did not have the impact anticipated as it was borne out of a paternalistic broadcast legacy, out of step with the trend towards distributed and collaborative discourse online that reassesses the notion that the public is simply a resource to be managed. This paper argues that the BBC experience provides lessons in how the media, and specifically public service broadcasters, can contribute towards greater political participation and democratic dialogue through the Internet by adopting Web 2.0 approaches that enable citizens to engage on different levels and at different times, depending on contexts.

    In this paper we will try to define the utility of Facebook's Personal Page marketing method. This tool that Facebook provides, is modelled and simulated using iThink in the context of a Facebook marketing agency. The paper has leveraged the system's dynamic paradigm to conduct Facebook marketing tools and methods modelling, using iThink™ system to implement them. It uses the design science research methodology for the proof of concept of the models and modelling processes. The following model has been developed for a social media marketing agent/company, Facebook platform oriented and tested in real circumstances. This model is finalized through a number of revisions and iterators of the design, development, simulation, testing and evaluation processes. The validity and usefulness of this Facebook marketing model for the day-to-day decision making are authenticated by the management of the company organization. Facebook's Personal Page method can be adjusted, depending on the situation, in order to maximize the total profit of the company which is to bring new customers, keep the interest of the old customers and deliver traffic to its website.

    2011-01-01

    The existing search engines sometimes give unsatisfactory search result for lack of any categorization of search result. If there is some means to know the preference of user about the search result and rank pages according to that preference, the result will be more useful and accurate to the user. In the present paper a web page ranking algorithm is being proposed based on syntactic classification of web pages. Syntactic Classification does not bother about the meaning of the content of a web page. The proposed approach mainly consists of three steps: select some properties of web pages based on user's demand, measure them, and give different weightage to each property during ranking for different types of pages. The existence of syntactic classification is supported by running fuzzy c-means algorithm and neural network classification on a set of web pages. The change in ranking for difference in type of pages but for same query string is also being demonstrated.

    The web page usage mining plays a vital role in enriching the page's content and structure based on the feedbacks received from the user's interactions with the page. This paper proposes a model for micro-managing the tracking activities by fine-tuning the mining from the page level to the segment level. The proposed model enables the web-master to identify the segments which receives more focus from users comparing with others. The segment level analytics of user actions provides an important metric to analyse the factors which facilitate the increase in traffic for the page. The empirical validation of the model is performed through prototype implementation.

    Full Text Available The amount of information on the web is always growing, thus powerful search tools are needed to search for such a large collection. Search engines in this direction help users so they can find their desirable information among the massive volume of information in an easier way. But what is important in the search engines and causes a distinction between them is page ranking algorithm used in them. In this paper a new page ranking algorithm based on "Weighted Page Ranking based on Visits of Links (WPRVOL Algorithm" for search engines is being proposed which is called WPR'VOL for short. The proposed algorithm considers the number of visits of first and second level in-links. The original WPRVOL algorithm takes into account the number of visits of first level in-links of the pages and distributes rank scores based on the popularity of the pages whereas the proposed algorithm considers both in-links of that page (first level in-links and in-links of the pages that point to it (second level in-links in order to calculation of rank of the page, hence more related pages are displayed at the top of search result list. In the summary it is said that the proposed algorithm assigns higher rank to pages that both themselves and pages that point to them be important.

  8. PageRank optimization applied to spam detection

    CERN Document Server

    Fercoq, Olivier

    2012-01-01

    We give a new link spam detection and PageRank demotion algorithm called MaxRank. Like TrustRank and AntiTrustRank, it starts with a seed of hand-picked trusted and spam pages. We define the MaxRank of a page as the frequency of visit of this page by a random surfer minimizing an average cost per time unit. On a given page, the random surfer selects a set of hyperlinks and clicks with uniform probability on any of these hyperlinks. The cost function penalizes spam pages and hyperlink removals. The goal is to determine a hyperlink deletion policy that minimizes this score. The MaxRank is interpreted as a modified PageRank vector, used to sort web pages instead of the usual PageRank vector. The bias vector of this ergodic control problem, which is unique up to an additive constant, is a measure of the "spamicity" of each page, used to detect spam pages. We give a scalable algorithm for MaxRank computation that allowed us to perform experimental results on the WEBSPAM-UK2007 dataset. We show that our algorithm o...

    Software testing coverage criteria play an important role in the whole testing process. The current coverage criteria for web applications are based on program or URL. They are not suitable for black-box test or intuitional to use. This paper defines a kind of test criteria based on page coverage sequences only navigated by web application, including Page_Single, Page_Post, Page_Pre,Page_Seq2, Page_SeqK. The test criteria based on page coverage sequences made by interactions between web application and browser are being under consideration after that. In order to avoid ambiguity of natural language, these coverage criteria are depicted using Z formal language. The empirical result shows that the criteria complement traditional coverage and fault detection capability criteria.

    A Web page extraetion method based on the layout of Web page is proposed in this paper to implementtasks of page cleaning and content extraction. Firstly, a tag-tree is constructed by analyzing the corresponding DOM structure of original page. Then the tree is partitioned into a set of blocks from bottom to up in terms of categories of tags and concerning information of nodes, furthermore, blocks are classified on the basis of the proportion of word, link and image in blocks. Next, by using VSM (Vector Space Model) , text eigenvector of page's subject is abstracted, which has been used to calculate degree of correlation between block ' s content and page ' s subject. In the light of degree of correlation, we can judge which blocks should be got rid of and which ones should be kept. The content blocks with high degree of correlation are kept to reconstruct the description of Web page. The method has been applied in a project concerning Talent Information Collection. Test results indicate effectiveness of the method in page cleaning and contentextraction.%本篇论文以去除网页噪声,整合网页内容为目标,提出了面向主题型网页,根据网页规划布局抽取网页内容的方法.算法首先分析原始网页的DOM结构生成标签树,再根据标签分类和对应节点的信息对标签树自底向上进行划分,并依据划分块的文字密度,链接密度及图片密度,分类信息块.进一步,提炼网页主题的文本特征向量,采用基于词条空间的文本相似度计算,获取划分块的主题相关度,以主题相关度为量化基准剔除噪声,识别网页主旨内容,重构页面描述.这一算法被应用于面向人才资讯的信息采集项目中,实验表明,算法适用于主题型网页的"去噪"及内容提取,具体应用中有较理想的表现.

  11. Controlling misses and false alarms in a machine learning framework for predicting uniformity of printed pages

    Science.gov (United States)

    Nguyen, Minh Q.; Allebach, Jan P.

    2015-01-01

    In our previous work1 , we presented a block-based technique to analyze printed page uniformity both visually and metrically. The features learned from the models were then employed in a Support Vector Machine (SVM) framework to classify the pages into one of the two categories of acceptable and unacceptable quality. In this paper, we introduce a set of tools for machine learning in the assessment of printed page uniformity. This work is primarily targeted to the printing industry, specifically the ubiquitous laser, electrophotographic printer. We use features that are well-correlated with the rankings of expert observers to develop a novel machine learning framework that allows one to achieve the minimum "false alarm" rate, subject to a chosen "miss" rate. Surprisingly, most of the research that has been conducted on machine learning does not consider this framework. During the process of developing a new product, test engineers will print hundreds of test pages, which can be scanned and then analyzed by an autonomous algorithm. Among these pages, most may be of acceptable quality. The objective is to find the ones that are not. These will provide critically important information to systems designers, regarding issues that need to be addressed in improving the printer design. A "miss" is defined to be a page that is not of acceptable quality to an expert observer that the prediction algorithm declares to be a "pass". Misses are a serious problem, since they represent problems that will not be seen by the systems designers. On the other hand, "false alarms" correspond to pages that an expert observer would declare to be of acceptable quality, but which are flagged by the prediction algorithm as "fails". In a typical printer testing and development scenario, such pages would be examined by an expert, and found to be of acceptable quality after all. "False alarm" pages result in extra pages to be examined by expert observers, which increases labor cost. But "false

    Purpose: The purpose is the development of a novel calibration method for dosimetry with Gafchromic EBT3 films. The method should be applicable for pretreatment verification of volumetric modulated arc, and intensity modulated radiotherapy. Because the exposed area on film can be large for such treatments, lateral scan errors must be taken into account. The correction for the lateral scan effect is obtained from the calibration data itself. Methods: In this work, the film measurements were modeled using their relative scan values (Transmittance, T). Inside the transmittance domain a linear combination and a parabolic lateral scan correction described the observed transmittance values. The linear combination model, combined a monomer transmittance state (T{sub 0}) and a polymer transmittance state (T{sub {infinity}}) of the film. The dose domain was associated with the observed effects in the transmittance domain through a rational calibration function. On the calibration film only simple static fields were applied and page sized films were used for calibration and measurements (treatment verification). Four different calibration setups were considered and compared with respect to dose estimation accuracy. The first (I) used a calibration table from 32 regions of interest (ROIs) spread on 4 calibration films, the second (II) used 16 ROIs spread on 2 calibration films, the third (III), and fourth (IV) used 8 ROIs spread on a single calibration film. The calibration tables of the setups I, II, and IV contained eight dose levels delivered to different positions on the films, while for setup III only four dose levels were applied. Validation was performed by irradiating film strips with known doses at two different time points over the course of a week. Accuracy of the dose response and the lateral effect correction was estimated using the dose difference and the root mean squared error (RMSE), respectively. Results: A calibration based on two films was the optimal

  15. Striations in PageRank-Ordered Matrices

    CERN Document Server

    Pennycuff, Corey

    2016-01-01

    Patterns often appear in a variety of large, real-world networks, and interesting physical phenomena are often explained by network topology as in the case of the bow-tie structure of the World Wide Web, or the small world phenomenon in social networks. The discovery and modelling of such regular patterns has a wide application from disease propagation to financial markets. In this work we describe a newly discovered regularly occurring striation pattern found in the PageRank ordering of adjacency matrices that encode real-world networks. We demonstrate that these striations are the result of well-known graph generation processes resulting in regularities that are manifest in the typical neighborhood distribution. The spectral view explored in this paper encodes a tremendous amount about the explicit and implicit topology of a given network, so we also discuss the interesting network properties, outliers and anomalies that a viewer can determine from a brief look at the re-ordered matrix.

    2001-01-01

    The goal of Western blotting, or more correctly, immunoblotting, is to identify with a specific antibody a particular antigen within a complex mixture of proteins that has been fractionated in a polyacrylamide gel and immobilized onto a membrane. Immunoblotting can be used to determine a number of important characteristics of protein antigens-the presence and quantity of an antigen, the relative molecular weight of the polypeptide chain, and the efficiency of extraction of the antigen.Immunoblotting occurs in six stages: (1) extraction and quantification of protein samples; (2) resolution of the protein sample in sodium dodecyl sulfatepolyacrylamide denaturing gel electrophoresis (SDS-PAGE); (3) transfer of the separated polypeptides to a membrane support; (4) blocking nonspecific binding sites on the membrane; (5) addition of antibodies; and (6) detection.Sample preparation is important for obtaining accurate separation of the proteins on the basis of molecular weight. Depending on whether an antigen is primarily extracellular, cytoplasmic, or membrane-associated different procedures might be required to prepare the sample initially. Although there are exceptions, many soluble nuclear and cytoplasmic proteins can be solubilized by lysis buffers that contain the nonionic detergent Nonidet P-40 (NP-40) and either no salt at all or relatively high concentrations of salt (e.g., 0.5 M NaCl). However, the efficiency of extraction is often greatly affected by pH of the buffer and the presence or absence of chelating agents such EDTA.

  17. Extraction of Flat and Nested Data Records from Web Pages

    CERN Document Server

    Hiremath, P S

    2010-01-01

    This paper studies the problem of identification and extraction of flat and nested data records from a given web page. With the explosive growth of information sources available on the World Wide Web, it has become increasingly difficult to identify the relevant pieces of information, since web pages are often cluttered with irrelevant content like advertisements, navigation-panels, copyright notices etc., surrounding the main content of the web page. Hence, it is useful to mine such data regions and data records in order to extract information from such web pages to provide value-added services. Currently available automatic techniques to mine data regions and data records from web pages are still unsatisfactory because of their poor performance. In this paper a novel method to identify and extract the flat and nested data records from the web pages automatically is proposed. It comprises of two steps : (1) Identification and Extraction of the data regions based on visual clues information. (2) Identificatio...

    The cities are not static environments. They change constantly. When we talk about traffic in the city, the evolution of traffic lights is a journey from mindless automation to increasingly intelligent, fluid traffic management. In our approach, presented in this paper, reinforcement-learning mechanism based on cost function is introduced to determine optimal decisions for each traffic light, based on the solution given by Larry Page for page ranking in Web environment (Page et al. (1999))...

    Full Text Available The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML page using AJAX (Asynchronous JavaScript and XML, with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: “Table”, “Folder”, and “Tile” functions. PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

    Full Text Available With the aim of maintaining morale on the Home Front, as well as getting the British population to trust in final victory, the British government put in place a hidden control of the BBC, which was regularly instructed as to what broadcast form propaganda should take on the Home Service. These secret, regular and precise guidelines were to result in the projection of an ultra-positive image of Great Britain and of the British at war. The systematic hero-making propaganda was to become gradually better organised, more subtle, and therefore more efficient as the years went by thanks to the expertise of BBC staff. Countless programmes were broadcast, which stressed the heroic virtues of British soldiers, of the Navy and of the R.A.F, or reminded the listeners of past heroes, the glorious history of Great Britain being systematically commemorated, thus exalting national pride daily. To the constant cult of the heroes of the Home Front (particularly of women corresponded an equally constant denigration of the Nazi enemy. Although there was no recourse to lies, the way both the military and the Home Front were presented was undoubtedly of a propaganda nature. Indeed, the aim was to win the hearts and minds of the British population by playing on two chords: on the one hand, turning the enemy into an evil beast, minimising defeats and difficulties, and, on the other hand, systematically extolling the power and glory of Great Britain and the innate qualities of the British.

  1. A thorough spring-clean for CERN's Web pages

    CERN Multimedia

    2001-01-01

    This coming Tuesday will see the unveiling of CERN's new user pages on the Web. Their simplified layout and design will make everybody's lives a whole lot easier. Stand by for Tuesday 17 April when, as announced in the Weekly Bulletin of 2 April (n°14/2001), the new newly-designed users welcome page will be hitting our screens as the default CERN home page. But don't worry, if you've got the blues for the good old blue-green home page it's still in service and, to ensure a smooth transition, will be maintained in parallel until 25 May. But in all likelihood you'll be quickly won over by the new-look pages, which are so much simpler to use. Welcome to the new Web! The aim of this revamp, led by the WPE (Web Public Education) group, is to simplify and introduce a more logical hierarchy into the menus and welcome pages on CERN's Intranet. In a second stage, the 'General Public' pages will get a similar makeover. The fact is that the number of links on the user pages, and in particular the welcome page...

  2. DISTRIBUTED APPROACH to WEB PAGE CATEGORIZATION USING MAPREDUCE PROGRAMMING MODEL

    Full Text Available The web is a large repository of information and to facilitate the search and retrieval of pages from it,categorization of web documents is essential. An effective means to handle the complexity of information retrieval from the internet is through automatic classification of web pages. Although lots of automatic classification algorithms and systems have been presented, most of the existing approaches are computationally challenging. In order to overcome this challenge, we have proposed a parallel algorithm, known as MapReduce programming model to automatically categorize the web pages. This approach incorporates three concepts. They are web crawler, MapReduce programming model and the proposed web page categorization approach. Initially, we have utilized web crawler to mine the World Wide Web and the crawled web pages are then directly given as input to the MapReduce programming model. Here the MapReduce programming model adapted to our proposed web page categorization approach finds the appropriate category of the web page according to its content. The experimental results show that our proposed parallel web page categorization approach achieves satisfactory results in finding the right category for any given web page.

    Page switching is a technique that increases the memory in microcontrollers without extending the address buses. This technique is widely used in the design of 8-bit MCUs. In this paper, we present an algorithm to reduce the overhead of page switching. To pursue small code size, we place the emphasis on the allocation of functions into suitable pages with a heuristic algorithm, thereby the cost-effective placement of page selection instructions. Our experimental results showed the optimization achieved a reduction in code size of 13.2 percent.

    2007-06-01

    With the rapid development of the World Wide Web, people benefit more and more from the sharing of information. However, Web pages with obscene, harmful, or illegal content can be easily accessed. It is important to recognize such unsuitable, offensive, or pornographic Web pages. In this paper, a novel framework for recognizing pornographic Web pages is described. A C4.5 decision tree is used to divide Web pages, according to content representations, into continuous text pages, discrete text pages, and image pages. These three categories of Web pages are handled, respectively, by a continuous text classifier, a discrete text classifier, and an algorithm that fuses the results from the image classifier and the discrete text classifier. In the continuous text classifier, statistical and semantic features are used to recognize pornographic texts. In the discrete text classifier, the naive Bayes rule is used to calculate the probability that a discrete text is pornographic. In the image classifier, the object's contour-based features are extracted to recognize pornographic images. In the text and image fusion algorithm, the Bayes theory is used to combine the recognition results from images and texts. Experimental results demonstrate that the continuous text classifier outperforms the traditional keyword-statistics-based classifier, the contour-based image classifier outperforms the traditional skin-region-based image classifier, the results obtained by our fusion algorithm outperform those by either of the individual classifiers, and our framework can be adapted to different categories of Web pages.

    2010-01-01

    This article provides an alternative perspective for measuring author impact by applying PageRank algorithm to a coauthorship network. A weighted PageRank algorithm considering citation and coauthorship network topology is proposed. We test this algorithm under different damping factors by evaluating author impact in the informetrics research community. In addition, we also compare this weighted PageRank with the h-index, citation, and program committee (PC) membership of the International Society for Scientometrics and Informetrics (ISSI) conferences. Findings show that this weighted PageRank algorithm provides reliable results in measuring author impact.

    2014-12-01

    We report that subunits of human nuclear proteasomes carry a previously unrecognised, constitutive posttranslational modification. Subunits with this modification are not visualised by SDS-PAGE, which is used in almost all denaturing protein gel electrophoresis. In contrast, CTAB-PAGE readily visualises such modified subunits. Thus, under most experimental conditions, with identical samples, SDS-PAGE yielded gel electrophoresis patterns for subunits of nuclear proteasomes which were misleading and strikingly different from those obtained with CTAB-PAGE. Initial analysis indicates a novel modification of a high negative charge with some similarity to polyADP-ribose, possibly explaining compatibility with (positively-charged) CTAB-PAGE but not (negatively-charged) SDS-PAGE and providing a mechanism for how nuclear proteasomes may interact with chromatin, DNA and other nuclear components.

  9. Socorro Students Translate NRAO Web Pages Into Spanish

    2002-07-01

    Six Socorro High School students are spending their summer working at the National Radio Astronomy Observatory (NRAO) on a unique project that gives them experience in language translation, World Wide Web design, and technical communication. Under the project, called "Un puente a los cielos," the students are translating many of NRAO's Web pages on astronomy into Spanish. "These students are using their bilingual skills to help us make basic information about astronomy and radio telescopes available to the Spanish-speaking community," said Kristy Dyer, who works at NRAO as a National Science Foundation postdoctoral fellow and who developed the project and obtained funding for it from the National Aeronautics and Space Administration. The students are: Daniel Acosta, 16; Rossellys Amarante, 15; Sandra Cano, 16; Joel Gonzalez, 16; Angelica Hernandez, 16; and Cecilia Lopez, 16. The translation project, a joint effort of NRAO and the NM Tech physics department, also includes Zammaya Moreno, a teacher from Ecuador, Robyn Harrison, NRAO's education officer, and NRAO computer specialist Allan Poindexter. The students are translating NRAO Web pages aimed at the general public. These pages cover the basics of radio astronomy and frequently-asked questions about NRAO and the scientific research done with NRAO's telescopes. "Writing about science for non-technical audiences has to be done carefully. Scientific concepts must be presented in terms that are understandable to non-scientists but also that remain scientifically accurate," Dyer said. "When translating this type of writing from one language to another, we need to preserve both the understandability and the accuracy," she added. For that reason, Dyer recruited 14 Spanish-speaking astronomers from Argentina, Mexico and the U.S. to help verify the scientific accuracy of the Spanish translations. The astronomers will review the translations. The project is giving the students a broad range of experience. "They are

    1997-07-01

    Document images in which different scripts, such as Chinese and Roman, appear on a single page pose a problem for optical character recognition (OCR) systems. This paper explores the use of script identification vectors in the analysis of multilingual document images. A script identification vector is calculated for each connected component in a document. The vector expresses the closest distance between the component and templates developed for each of thirteen scripts, including Arabic, Chinese, Cyrillic, and Roman. The authors calculate the first three principal components within the resulting thirteen-dimensional space for each image. By mapping these components to red, green, and blue, they can visualize the information contained in the script identification vectors. The visualization of several multilingual images suggests that the script identification vectors can be used to segment images into script-specific regions as large as several paragraphs or as small as a few characters. The visualized vectors also reveal distinctions within scripts, such as font in Roman documents, and kanji vs. kana in Japanese. Results are best for documents containing highly dissimilar scripts such as Roman and Japanese. Documents containing similar scripts, such as Roman and Cyrillic will require further investigation.

    2012-11-01

    We propose the PageRank model of opinion formation and investigate its rich properties on real directed networks of the Universities of Cambridge and Oxford, LiveJournal, and Twitter. In this model, the opinion formation of linked electors is weighted with their PageRank probability. Such a probability is used by the Google search engine for ranking of web pages. We find that the society elite, corresponding to the top PageRank nodes, can impose its opinion on a significant fraction of the society. However, for a homogeneous distribution of two opinions, there exists a bistability range of opinions which depends on a conformist parameter characterizing the opinion formation. We find that the LiveJournal and Twitter networks have a stronger tendency to a totalitarian opinion formation than the university networks. We also analyze the Sznajd model generalized for scale-free networks with the weighted PageRank vote of electors.

    2013-01-01

    Full Text Available We introduce a partition of the web pages particularly suited to the PageRank problems in which the web link graph has a nested block structure. Based on the partition of the web pages, dangling nodes, common nodes, and general nodes, the hyperlink matrix can be reordered to be a more simple block structure. Then based on the parallel computation method, we propose an algorithm for the PageRank problems. In this algorithm, the dimension of the linear system becomes smaller, and the vector for general nodes in each block can be calculated separately in every iteration. Numerical experiments show that this approach speeds up the computation of PageRank.

    p53 is a central mediator of cellular stress responses, and its precise regulation is essential for the normal progression of hematopoiesis. MYSM1 is an epigenetic regulator essential for the maintenance of hematopoietic stem cell (HSC) function, hematopoietic progenitor survival, and lymphocyte development. We recently demonstrated that all developmental and hematopoietic phenotypes of Mysm1 deficiency are p53-mediated and rescued in the Mysm1(-/-)p53(-/-) mouse model. However, the mechanisms triggering p53 activation in Mysm1(-/-) HSPCs, and the pathways downstream of p53 driving different aspects of the Mysm1(-/-) phenotype remain unknown. Here we show the transcriptional activation of p53 stress responses in Mysm1(-/-) HSPCs. Mechanistically, we find that the MYSM1 protein associates with p53 and colocalizes to promoters of classical p53-target genes Bbc3/PUMA (p53 upregulated modulator of apoptosis) and Cdkn1a/p21. Furthermore, it antagonizes their p53-driven expression by modulating local histone modifications (H3K27ac and H3K4me3) and p53 recruitment. Using double-knockout mouse models, we establish that PUMA, but not p21, is an important mediator of p53-driven Mysm1(-/-) hematopoietic dysfunction. Specifically, Mysm1(-/-)Puma(-/-) mice show full rescue of multipotent progenitor (MPP) viability, partial rescue of HSC quiescence and function, but persistent lymphopenia. Through transcriptome analysis of Mysm1(-/-)Puma(-/-) MPPs, we demonstrate strong upregulation of other p53-induced mediators of apoptosis and cell-cycle arrest. The full viability of Mysm1(-/-)Puma(-/-) MPPs, despite strong upregulation of many other pro-apoptotic mediators, establishes PUMA as the essential non-redundant effector of p53-induced MPP apoptosis. Furthermore, we identify potential mediators of p53-dependent but PUMA-independent Mysm1(-/-)hematopoietic deficiency phenotypes. Overall, our study provides novel insight into the cell-type-specific roles of p53 and its downstream

    The mycorrhiza helper bacterial strain Pseudomonas fluorescens BBc6R8 enhances the establishment of Laccaria bicolor S238N ectomycorrhizae by improving the pre-symbiotic growth and survival of the fungus. Nothing is known about the effect of the ectomycorrhizal fungus on the helper bacteria or the molecules that are involved in the interaction. In this study, we have monitored the population density of the helper strain P. fluorescens BBc6R8 in soils inoculated with L. bicolor and in control soils and found that the ectomycorhizal fungus improves the survival of the helper bacteria. We investigated the identity of the fungal and bacterial metabolites involved in this reciprocal growth-promoting effect using a combination of growth measurements, chemoattractant assays, HPLC and in silico genome analyses. We showed that trehalose, a disaccharide that accumulates to high levels in the fungal hyphae, chemoattracted and promoted the growth of the helper bacteria. Meanwhile, P. fluorescens BBc6R8 produced thiamine at concentrations that enhanced the fungal growth in vitro. Altogether our data indicate that the interaction between the two microorganisms is beneficial for both species and relies, at least in part, on trophic mutualism.

    Kuppusamy, K S; 10.5121/ijist.2012.2104

    2012-01-01

    In the view of massive content explosion in World Wide Web through diverse sources, it has become mandatory to have content filtering tools. The filtering of contents of the web pages holds greater significance in cases of access by minor-age people. The traditional web page blocking systems goes by the Boolean methodology of either displaying the full page or blocking it completely. With the increased dynamism in the web pages, it has become a common phenomenon that different portions of the web page holds different types of content at different time instances. This paper proposes a model to block the contents at a fine-grained level i.e. instead of completely blocking the page it would be efficient to block only those segments which holds the contents to be blocked. The advantages of this method over the traditional methods are fine-graining level of blocking and automatic identification of portions of the page to be blocked. The experiments conducted on the proposed model indicate 88% of accuracy in filter...

    This paper presents our studies on the rearrangement of links from the structure of websites for the purpose of improving the valuation of a page or group of pages as established by a ranking function as Google's PageRank. We build our topological taxonomy starting from unidirectional and bidirectional rooted trees, and up to more complex hierarchical structures as cyclical rooted trees (obtained by closing cycles on bidirectional trees) and PR--digraph rooted trees (digraphs whose condensation digraph is a rooted tree that behave like cyclical rooted trees). We give different modifications on the structure of these trees and its effect on the valuation given by the PageRank function. We derive closed formulas for the PageRank of the root of various types of trees, and establish a hierarchy of these topologies in terms of PageRank. We show that the PageRank of the root of cyclical and PR--digraph trees basically depends on the number of vertices per level and the number of cycles of distinct lengths among lev...

    2014-01-01

    Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages.

  9. An Efficient Web Page Ranking for Semantic Web

    2014-01-01

    With the enormous amount of information presented on the web, the retrieval of relevant information has become a serious problem and is also the topic of research for last few years. The most common tools to retrieve information from web are search engines like Google. The Search engines are usually based on keyword searching and indexing of web pages. This approach is not very efficient as the result-set of web pages obtained include large irrelevant pages. Sometimes even the entire result-set may contain lot of irrelevant pages for the user. The next generation of search engines must address this problem. Recently, many semantic web search engines have been developed like Ontolook, Swoogle, which help in searching meaningful documents presented on semantic web. In this process the ranking of the retrieved web pages is very crucial. Some attempts have been made in ranking of semantic web pages but still the ranking of these semantic web documents is neither satisfactory and nor up to the user's expectations. In this paper we have proposed a semantic web based document ranking scheme that relies not only on the keywords but also on the conceptual instances present between the keywords. As a result only the relevant page will be on the top of the result-set of searched web pages. We explore all relevant relations between the keywords exploring the user's intention and then calculate the fraction of these relations on each web page to determine their relevance. We have found that this ranking technique gives better results than those by the prevailing methods.

    2014-04-29

    A method and system for providing a memory access check on a processor including the steps of detecting accesses to a memory device including level-1 cache using a wakeup unit. The method includes invalidating level-1 cache ranges corresponding to a guard page, and configuring a plurality of wakeup address compare (WAC) registers to allow access to selected WAC registers. The method selects one of the plurality of WAC registers, and sets up a WAC register related to the guard page. The method configures the wakeup unit to interrupt on access of the selected WAC register. The method detects access of the memory device using the wakeup unit when a guard page is violated. The method generates an interrupt to the core using the wakeup unit, and determines the source of the interrupt. The method detects the activated WAC registers assigned to the violated guard page, and initiates a response.

    2011-01-01

    To cope with the increasing demand of wireless communication services multi-carrier systems are being used. Radio resources are very limited and efficient usages of these resources are inevitable to get optimum performance of the system. Paging channel is a low-bandwidth channel and one of the most important channels on which system performance depends significantly. Therefore it is vulnerable to even moderate overloads. In this paper, an efficient paging algorithm, Concurrent Search, is proposed for efficient use of paging channel in Multi- carrier CDMA system instead of existing sequential searching algorithm. It is shown by the simulation that the paging performance in proposed algorithm is far better than the existing system.

    2012-01-01

    We propose the PageRank model of opinion formation and investigate its rich properties on real directed networks of Universities of Cambridge and Oxford, LiveJournal and Twitter. In this model the opinion formation of linked electors is weighted with their PageRank probability. We find that the society elite, corresponding to the top PageRank nodes, can impose its opinion to a significant fraction of the society. However, for a homogeneous distribution of two opinions there exists a bistability range of opinions which depends on a conformist parameter characterizing the opinion formation. We find that LiveJournal and Twitter networks have a stronger tendency to a totalitar opinion formation. We also analyze the Sznajd model generalized for scale-free networks with the weighted PageRank vote of electors.

    Mullins, Matt; 10.1109/WI-IAT.2010.289

    2011-01-01

    Collaborative tagging has emerged as a popular and effective method for organizing and describing pages on the Web. We present Treelicious, a system that allows hierarchical navigation of tagged web pages. Our system enriches the navigational capabilities of standard tagging systems, which typically exploit only popularity and co-occurrence data. We describe a prototype that leverages the Wikipedia category structure to allow a user to semantically navigate pages from the Delicious social bookmarking service. In our system a user can perform an ordinary keyword search and browse relevant pages but is also given the ability to broaden the search to more general topics and narrow it to more specific topics. We show that Treelicious indeed provides an intuitive framework that allows for improved and effective discovery of knowledge.

  4. Decadent Perfume: Under the Skin and Through the Page

    Directory of Open Access Journals (Sweden)

    Cheryl Krueger

    2014-10-01

    Full Text Available At the fin de siècle, there is  tendency in learned discourse to discredit the salubrious properties of fragrance, and more radically, to deem perfume use potentially toxic and aberrant. It is as if suspicion of perfume supplanted the fear of miasma (smell-borne contagion as an olfactive indicator of hygienic and social danger. But unlike the involuntary absorption of disease-ridden smells, fin-de-siècle perfume abuse (be it heightened sensitivity to odor or overzealous spritzing, huffing, injecting, or imbibing was a deviant behavior, not an environmental hazard, and one—accurately or not—often ascribed to women and linked to mental and emotional instability.I posit that the more obtainable and feminized perfume became, the more toxic and symptomatic its portrayal. A growing suspicion of perfume, and vigilance to its implementation and proximity to the body, coincided with an increased likelihood that women of all classes might leave their scent trail in spaces beyond the privacy of the boudoir.The essay focuses on two remarkable yet nearly forgotten fin-de-siècle manifestations of decadent perfuming, in texts ad images whose discourse intersects with that of hygiene and medical reports of their time. The first is Edmond de Goncourt’s 1884 novel Chérie, the fictional study of a young hysteric with a decadent, erotic connection to perfume. The second, a real-life swooning perfume-lover, involves the nameless consumer to whom an unusual gadget called the Lance-parfum Rodo (1896 was marketed. Like Goncourt’s Chérie, Alphonse Mucha’s ad poster for the Rodo, and the surprisingly hazardous product itself, contribute to reciprocal discourses on the social and literary implications of permeating the body and the page with perfume.

    2012-11-01

    Full Text Available Social Network Analysis is mapping and measuring of relationships and flows of information between people, organizations, computers, or other information or knowledge processing entities. Social media systems such as blogs, LinkedIn, you tube are allows users to share content media, etc. Blog is a social network notepad service with consider on user interactions. In this paper study the link predictionand page ranking using MozRank algorithm using blog websites. It finds out how all the websites on the internet link to each other with the largest Link Intelligence database. As link data is also a component of search engine ranking, understanding the link profile of Search Engine positioning. Here the MozRank algorithm is using backlinks from blog websites and linking websites quality. Good websites with many backlinks which linking the corresponding WebPage give highly value of MozRank. MozRank can be improved a web page's by getting lots of links from semi-popular pages or a few links from very popular pages. The algorithm for page ranking must work differently and MozRank is more comprehensive and accurate than Goggle’s page rank. Another tool is Open Site Explorer that is ability to compare five URL's against each other. Open Site Explorer’s Compare Link Metrics option is how one measures pagelevel metrics, the other domain. This result can help to generate a chart form for the comparative URLs. A comparison chart of the important metrics for these pages is shown which makes it very clear and easy to compare the data between the five URL's.

  7. Relevant Pages in semantic Web Search Engines using Ontology

    Directory of Open Access Journals (Sweden)

    Jemimah Simon

    2012-03-01

    Full Text Available In general, search engines are the most popular means of searching any kind of information from the Internet. Generally, keywords are given to the search engine and the Web database returns the documents containing specified keywords. In many situations, irrelevant results are given as results to the user query since different keywords are used in different forms in various documents. The development of the next generation Web, Semantic Web, will change this situation. This paper proposes a prototype of relation-based search engine which ranks the page according to the user query and on annotated results. Page sub graph is computed for each annotated page in the result set by generating all possible combinations for the relation in the sub graph. A relevance score is computed for each annotated page using a probability measure. A relation based ranking model is used which displays the pages in the final result set according to their relevance score. This ranking is provided by considering keyword-concept associations. Thus, the final result set contains pages in the order of their constrained relevant scores.

  8. Metadata Schema Used in OCLC Sampled Web Pages

    Directory of Open Access Journals (Sweden)

    2005-12-01

    Full Text Available The tremendous growth of Web resources has made information organization and retrieval more and more difficult. As one approach to this problem, metadata schemas have been developed to characterize Web resources. However, many questions have been raised about the use of metadata schemas such as which metadata schemas have been used on the Web? How did they describe Web accessible information? What is the distribution of these metadata schemas among Web pages? Do certain schemas dominate the others? To address these issues, this study analyzed 16,383 Web pages with meta tags extracted from 200,000 OCLC sampled Web pages in 2000. It found that only 8.19% Web pages used meta tags; description tags, keyword tags, and Dublin Core tags were the only three schemas used in the Web pages. This article revealed the use of meta tags in terms of their function distribution, syntax characteristics, granularity of the Web pages, and the length distribution and word number distribution of both description and keywords tags.

    locality data by page-color, limiting cache conflicting domain of weak locality data and strong locality data in specified page-color address space to reduce cache misses and latency of data processing. Compared with typical page-coloring approach, we don't need modifying the kernel module of OS, we can achieve better address space utilization, and can support cache partitioning inside the query processing. In experiments, we verify the feasibility and performance of W-order scan in typical multiple table join operation by simulating cache behavior patterns and measuring real processing cache metrics by cache monitoring tools. The experimental results show that we can effectively reduce cache misses and improve main memory database performance by controlling sequential scan order with an application software-level cache partitioning approach.

    Liu, Dong; Wang, Yongtao; Tang, Zhi; Li, Luyuan; Gao, Liangcai

    2013-12-01

    Comic page image understanding aims to analyse the layout of the comic page images by detecting the storyboards and identifying the reading order automatically. It is the key technique to produce the digital comic documents suitable for reading on mobile devices. In this paper, we propose a novel comic page image understanding method based on edge segment analysis. First, we propose an efficient edge point chaining method to extract Canny edge segments (i.e., contiguous chains of Canny edge points) from the input comic page image; second, we propose a top-down scheme to detect line segments within each obtained edge segment; third, we develop a novel method to detect the storyboards by selecting the border lines and further identify the reading order of these storyboards. The proposed method is performed on a data set consisting of 2000 comic page images from ten printed comic series. The experimental results demonstrate that the proposed method achieves satisfactory results on different comics and outperforms the existing methods.

  12. Network and User-Perceived Performance of Web Page Retrievals

    Science.gov (United States)

    Kruse, Hans; Allman, Mark; Mallasch, Paul

    1998-01-01

    The development of the HTTP protocol has been driven by the need to improve the network performance of the protocol by allowing the efficient retrieval of multiple parts of a web page without the need for multiple simultaneous TCP connections between a client and a server. We suggest that the retrieval of multiple page elements sequentially over a single TCP connection may result in a degradation of the perceived performance experienced by the user. We attempt to quantify this perceived degradation through the use of a model which combines a web retrieval simulation and an analytical model of TCP operation. Starting with the current HTTP/l.1 specification, we first suggest a client@side heuristic to improve the perceived transfer performance. We show that the perceived speed of the page retrieval can be increased without sacrificing data transfer efficiency. We then propose a new client/server extension to the HTTP/l.1 protocol to allow for the interleaving of page element retrievals. We finally address the issue of the display of advertisements on web pages, and in particular suggest a number of mechanisms which can make efficient use of IP multicast to send advertisements to a number of clients within the same network.

  13. Relating Web pages to enable information-gathering tasks

    2008-01-01

    We argue that relationships between Web pages are functions of the user's intent. We identify a class of Web tasks - information-gathering - that can be facilitated by a search engine that provides links to pages which are related to the page the user is currently viewing. We define three kinds of intentional relationships that correspond to whether the user is a) seeking sources of information, b) reading pages which provide information, or c) surfing through pages as part of an extended information-gathering process. We show that these three relationships can be productively mined using a combination of textual and link information and provide three scoring mechanisms that correspond to them: {\\em SeekRel}, {\\em FactRel} and {\\em SurfRel}. These scoring mechanisms incorporate both textual and link information. We build a set of capacitated subnetworks - each corresponding to a particular keyword - that mirror the interconnection structure of the World Wide Web. The scores are computed by computing flows on ...

    2011-01-01

    This paper aims to identify whether different weighted PageRank algorithms can be applied to author citation networks to measure the popularity and prestige of a scholar from a citation perspective. Information Retrieval (IR) was selected as a test field and data from 1956-2008 were collected from Web of Science (WOS). Weighted PageRank with citation and publication as weighted vectors were calculated on author citation networks. The results indicate that both popularity rank and prestige rank were highly correlated with the weighted PageRank. Principal Component Analysis (PCA) was conducted to detect relationships among these different measures. For capturing prize winners within the IR field, prestige rank outperformed all the other measures.

    Geeta, R B; Totad, Shasikumar G; D, Prasad Reddy P V G

    2011-01-01

    The one of the most time consuming steps for association rule mining is the computation of the frequency of the occurrences of itemsets in the database. The hash table index approach converts a transaction database to an hash index tree by scanning the transaction database only once. Whenever user requests for any Uniform Resource Locator (URL), the request entry is stored in the Log File of the server. This paper presents the hash index table structure, a general and dense structure which provides web page set extraction from Log File of server. This hash table provides information about the original database. Web Page set mining (WPs-Mine) provides a complete representation of the original database. This approach works well for both sparse and dense data distributions. Web page set mining supported by hash table index shows the performance always comparable with and often better than algorithms accessing data on flat files. Incremental update is feasible without reaccessing the original transactional databa...

    Subscriber satisfaction and maximum radio resource utilization are the pivotal criteria in communication system design. In multi-Carrier CDMA system, different paging algorithms are used for locating user within the shortest possible time and best possible utilization of radio resources. Different paging algorithms underscored different techniques based on the different purposes. However, low servicing time of sequential search and better utilization of radio resources of concurrent search can be utilized simultaneously by swapping of the algorithms. In this paper, intelligent mechanism has been developed for dynamic algorithm assignment basing on time-varying traffic demand, which is predicted by radial basis neural network; and its performance has been analyzed are based on prediction efficiency of different types of data. High prediction efficiency is observed with a good correlation coefficient (0.99) and subsequently better performance is achieved by dynamic paging algorithm assignment. This claim is sub...

  19. Experimental Results on Statistical Approaches to Page Replacement Policies

    Energy Technology Data Exchange (ETDEWEB)

    LEUNG,VITUS J.; IRANI,SANDY

    2000-12-08

    This paper investigates the questions of what statistical information about a memory request sequence is useful to have in making page replacement decisions: Our starting point is the Markov Request Model for page request sequences. Although the utility of modeling page request sequences by the Markov model has been recently put into doubt, we find that two previously suggested algorithms (Maximum Hitting Time and Dominating Distribution) which are based on the Markov model work well on the trace data used in this study. Interestingly, both of these algorithms perform equally well despite the fact that the theoretical results for these two algorithms differ dramatically. We then develop succinct characteristics of memory access patterns in an attempt to approximate the simpler of the two algorithms. Finally, we investigate how to collect these characteristics in an online manner in order to have a purely online algorithm.

    Grahame, Michael; Laberge, Jason; Scialfa, Charles T

    2004-01-01

    Reaction time, eye movements, and errors were measured during visual search of Web pages to determine age-related differences in performance as a function of link size, link number, link location, and clutter. Participants (15 young adults, M = 23 years; 14 older adults, M = 57 years) searched Web pages for target links that varied from trial to trial. During one half of the trials, links were enlarged from 10-point to 12-point font. Target location was distributed among the left, center, and bottom portions of the screen. Clutter was manipulated according to the percentage of used space, including graphics and text, and the number of potentially distracting nontarget links was varied. Increased link size improved performance, whereas increased clutter and links hampered search, especially for older adults. Results also showed that links located in the left region of the page were found most easily. Actual or potential applications of this research include Web site design to increase usability, particularly for older adults.

    Chakhmakhchyan, L

    2013-01-01

    We consider a PageRank model of opinion formation on Ulam networks, generated by the intermittency map and the typical Chirikov map. The Ulam networks generated by these maps have certain similarities with such scale-free networks as the World Wide Web (WWW), showing an algebraic decay of the PageRank probability. We find that the opinion formation process on Ulam networks have certain similarities but also distinct features comparing to the WWW. We attribute these distinctions to internal differences in network structure of the Ulam and WWW networks. We also analyze the process of opinion formation in the frame of generalized Sznajd model which protects opinion of small communities.

    This paper describes and evaluates the public health web pages classification model based on key phrase extraction and matching. Easily extendible both in terms of new classes as well as the new language this method proves to be a good solution for text classification faced with the total lack of training data. To evaluate the proposed solution we have used a small collection of public health related web pages created by a double blind manual classification. Our experiments have shown that by choosing the adequate threshold value the desired value for either precision or recall can be achieved.

    The 2nd PAGES global monsoon symposium which was held in Tongji University, Shanghai, China, from September 13 to 15, 2010, discussed four topics, namely the global monsoon concept, global correlation of regional monsoons, proxies of global monsoon intensity and monsoon related extreme hydrological events.Aside from the inter-annual variability associated with ENSO etc, this symposium discussed monsoons from inter-decadal to geological long-term cycles and the driving forces of their evolution and variations in a global scale.As a consensus, the symposium is not just providing a global view of regional monsoons, rather, it provides a new view of the regional monsoons as a global system.The global monsoon directly responds to external forcing, as well as interacts with high latitude processes through teleconnection.%第二届PAGES全球季风研讨会探讨了全球季风的概念,讨论了区域性季风系统之间的对比关系,评估并提出了新的古季风强度的替代性指标,讨论了与季风关联的极端水文事件.研讨会从多时间尺度上综合考虑季风系统的变化规律及其驱动机制,除了与厄尔尼诺相关的年际变化,还涵盖了从年代际到地质长周期的各种时间尺度上季风系统的驱动机制.我们对季风的研究需要从"全球性"和"多尺度"着眼,力争取得全新的认识.

    Science.gov (United States)

    Kootsey, J Mailen; Siriphongs, Daniel; McAuley, Grant

    2004-01-01

    A new Web software architecture, NumberLinX (NLX), has been integrated into a commercial Web design program to produce a drag-and-drop environment for building interactive simulations. NLX is a library of reusable objects written in Java, including input, output, calculation, and control objects. The NLX objects were added to the palette of available objects in the Web design program to be selected and dropped on a page. Inserting an object in a Web page is accomplished by adding a template block of HTML code to the page file. HTML parameters in the block must be set to user-supplied values, so the HTML code is generated dynamically, based on user entries in a popup form. Implementing the object inspector for each object permits the user to edit object attributes in a form window. Except for model definition, the combination of the NLX architecture and the Web design program permits construction of interactive simulation pages without writing or inspecting code.

  5. Modified Weighted PageRank Algorithm using Time Spent on Links

    Directory of Open Access Journals (Sweden)

    Priyanka Bauddha

    2014-09-01

    Full Text Available With dynamic growth and increasing data on the web, it is very difficult to find relevant information for a user. Large numbers of pages are returned by search engine in response of user’s query. The ranking algorithms have been developed to prioritize the search results so that more relevant pages are displayed at the top. Various ranking algorithms based on web structure mining and web usage mining such as PageRank, Weighted PageRank, PageRank with VOL and Weighted PageRank with VOL have been developed but they are not able to endure with the time spent by user on a particular web page. If user is conferring more time on a web page that signifies the page is more relevant to user. The proposed algorithm consolidates time spent with the Weighted PageRank using Visit of Links.

  8. HTML Tags as Extraction Cues for Web Page Description Construction

    Directory of Open Access Journals (Sweden)

    Timothy C. Craven

    2003-01-01

    Full Text Available Using four previously identified samples of Web pages containing meta-tagged descriptions, the value of meta-tagged keywords, the first 200 characters of the body, and text marked with common HTML tags as extracts helpful for writing summaries was estimated by applying two measures: density of description words and density of two-word description phrases. Generally, titles and keywords showed the highest densities. Parts of the body showed densities not much different from the body as a whole: somewhat higher for the first 200 characters and for text tagged with "center" and "font"; somewhat lower for text tagged with "a"; not significantly different for "table" and "div". Evidence of non-random clumping of description words in the body of some pages nevertheless suggests that further pursuit of automatic passage extraction methods from the body may be worthwhile. Implications of the findings for aids to summarization, and specifically the TexNet32 package, are discussed.

  10. Digital libraries and World Wide Web sites and page persistence.

    Directory of Open Access Journals (Sweden)

    Wallace Koehler

    1999-01-01

    Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some

    2007-01-01

    The relative worst order ratio, a new measure for the quality of on-line algorithms, was recently defined and applied to two bin packing problems. Here, we apply it to the paging problem and obtain the following results: We devise a new deterministic paging algorithm, Retrospective-LRU, and show...... that it performs better than LRU. This is supported by experimental results, but contrasts with the competitive ratio. All deterministic marking algorithms have the same competitive ratio, but here we find that LRU is better than FWF. According to the relative worst order ratio, no deterministic marking algorithm...... can be significantly better than LRU, but the randomized algorithm MARK is better than LRU. Finally, look-ahead is shown to be a significant advantage, in contrast to the competitive ratio, which does not reflect that look-ahead can be helpful....

    Eun-jung HAN; Chee-onn WONG; Kee-chul JUNG; Kyung-ho LEE; Eun-yi KIM

    2009-01-01

    Previously we have designed and implemented new image browsing facilities to support effective offline image contents on mobile devices with limited capabilities: low bandwidth, small display, and slow processing. In this letter, we fulfill the automatic production of cartoon contents fitting small-screen display, and introduce a clustering method useful for various types of cartoon images as a prerequisite stage for preserving semantic meaning. The usage of neural networks is to properly cut the various forms of pages. Texture information that is useful for grayscale image segmentation gives us a good clue for page layout analysis using the multilayer perceptron (MLP) based x-y recursive algorithm. We also automatically frame the segment MLP using agglomerative segmentation. Our experimental results show that the combined approaches yield good results of segmentation for several cartoons.

    2014-09-01

    Full Text Available A novel fluorescence-based staining method was developed for phosphoprotein analysis in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE. Similar to the mechanism of immobilized metal ion affinity chromatography (IMAC, the method employed quercetin–aluminum (III-appended complex as a fluoroprobe to selectively visualize phosphorylated proteins among total proteins. According to the results, as low as 16–32 ng of phosphoproteins (α-casein, β-casein and phosvitin could be selectively detected in 90 min with a wide linear dynamic range. In addition, the specificity of this novel stain for phosphoproteins was confirmed by 1-D and 2-D SDS-PAGE, dephosphorylation, western blot and liquid chromatography–mass spectrometry analysis (LC–MS/MS, respectively.

  14. User Modeling Combining Access Logs, Page Content and Semantics

    CERN Document Server

    Fortuna, Blaz; Grobelnik, Marko

    2011-01-01

    The paper proposes an approach to modeling users of large Web sites based on combining different data sources: access logs and content of the accessed pages are combined with semantic information about the Web pages, the users and the accesses of the users to the Web site. The assumption is that we are dealing with a large Web site providing content to a large number of users accessing the site. The proposed approach represents each user by a set of features derived from the different data sources, where some feature values may be missing for some users. It further enables user modeling based on the provided characteristics of the targeted user subset. The approach is evaluated on real-world data where we compare performance of the automatic assignment of a user to a predefined user segment when different data sources are used to represent the users.

    Mailen Kootsey, J; McAuley, Grant; Bernal, Julie

    2005-01-01

    A software system is described for building interactive simulations and other numerical calculations in Web pages. The system is based on a new Java-based software architecture named NumberLinX (NLX) that isolates each function required to build the simulation so that a library of reusable objects could be assembled. The NLX objects are integrated into a commercial Web design program for coding-free page construction. The model description is entered through a wizard-like utility program that also functions as a model editor. The complete system permits very rapid construction of interactive simulations without coding. A wide range of applications are possible with the system beyond interactive calculations, including remote data collection and processing and collaboration over a network.

    Full Text Available Predicting the next page to be accessed by the Webusers has attracted a large amount of research. In this paper, anew web usage mining approach is proposed to predict next pageaccess. It is proposed to identify similar access patterns from weblog using K-mean clustering and then Markov model is used forprediction for next page accesses. The tightness of clusters isimproved by setting similarity threshold while forming clusters.In traditional recommendation models, clustering by nonsequentialdata decreases recommendation accuracy. In thispaper involve incorporating clustering with low order markovmodel which can improve the prediction accuracy. The main areaof research in this paper is pre processing and identification ofuseful patterns from web data using mining techniques with thehelp of open source software.

    In February 1997, the Emerging Infections Network (EIN) established an electronic mail conference to facilitate discussions about emerging infectious diseases and related topics among its members and public health officials. Later that year, the EIN opened its section of the Infectious Diseases Society of America's home page. The EIN Web page was developed to give its members an alternative route for responding to EIN surveys and to facilitate rapid dispersal of EIN reports. The unrestricted portion of the site allows visitors access to information about the EIN and to published EIN reports on specific topics. For the most part, these are brief summaries or abstracts. In the restricted, password-protected portion of the EIN site, members can access the detailed, original reports from EIN queries and the comprehensive listings of member observations. Search functions in both portions of the EIN site enhance the retrieval of reports and observations on specific topics.

    2016-01-01

    PageRank centrality is used by Google for ranking web-pages to present search result for a user query. Here, we have shown that PageRank value of a vertex also depends on its intrinsic, non-network contribution. If the intrinsic, non-network contributions of the vertices are proportional to their degrees or zeros, then their PageRank centralities become proportion to their degrees. Some simulations and empirical data are used to support our study. In addition, we have shown that localization of PageRank centrality depends upon the same intrinsic, non-network contribution.

  6. A Novel Approach for Web Page Set Mining

    Directory of Open Access Journals (Sweden)

    R.B.Geeta

    2011-11-01

    Full Text Available The one of the most time consuming steps for association rule mining is the computation of the frequency of the occurrences of itemsets in the database. The hash table index approach converts a transaction database to an hash index tree by scanning the transaction database only once. Whenever user requests for any Uniform Resource Locator (URL, the request entry is stored in the Log File of the server. This paper presents the hash index table structure, a general and dense structure which provides web page set extraction from Log File of server. This hash table provides information about the original database. Web Page set mining (WPs-Mine provides a complete representation of the original database. This approach works well for both sparse and dense data distributions. Web page set mining supported by hash table index shows the performance always comparable with and often better than algorithms accessing data on flat files. Incremental update is feasible without reaccessing the original transactional database.

  7. Document representations for classification of short web-page descriptions

    Directory of Open Access Journals (Sweden)

    Radovanović Miloš

    2008-01-01

    Full Text Available Motivated by applying Text Categorization to classification of Web search results, this paper describes an extensive experimental study of the impact of bag-of- words document representations on the performance of five major classifiers - Naïve Bayes, SVM, Voted Perceptron, kNN and C4.5. The texts, representing short Web-page descriptions sorted into a large hierarchy of topics, are taken from the dmoz Open Directory Web-page ontology, and classifiers are trained to automatically determine the topics which may be relevant to a previously unseen Web-page. Different transformations of input data: stemming, normalization, logtf and idf, together with dimensionality reduction, are found to have a statistically significant improving or degrading effect on classification performance measured by classical metrics - accuracy, precision, recall, F1 and F2. The emphasis of the study is not on determining the best document representation which corresponds to each classifier, but rather on describing the effects of every individual transformation on classification, together with their mutual relationships. .

    Full Text Available To effectively manage the great amount of data on Arabic web pages and to enable the classification of relevant information are very important research problems. Studies on sentiment text mining have been very limited in the Arabic language because they need to involve deep semantic processing. Therefore, in this paper, we aim to retrieve machine-understandable data with the help of a Web content mining technique to detect covert knowledge within these data. We propose an approach to achieve clustering with semantic similarities. This approach comprises integrating k-means document clustering with semantic feature extraction and document vectorization to group Arabic web pages according to semantic similarities and then show the semantic annotation. The document vectorization helps to transform text documents into a semantic class probability distribution or semantic class density. To reach semantic similarities, the approach extracts the semantic class features and integrates them into the similarity weighting schema. The quality of the clustering result has evaluated the use of the purity and the mean intra-cluster distance (MICD evaluation measures. We have evaluated the proposed approach on a set of common Arabic news web pages. We have acquired favorable clustering results that are effective in minimizing the MICD, expanding the purity and lowering the runtime.

  9. Space Mission : Y3K

    2001-01-01

    ESA and the APME are hosting a contest for 10 - 15 year olds in nine European countries (Austria, Belgium, France, Germany, Italy, the Netherlands, Spain, Sweden and the United Kingdom). The contest is based on an interactive CD ROM, called Space Mission: Y3K, which explores space technology and shows some concrete uses of that technology in enhancing the quality of life on Earth. The CD ROM invites kids to join animated character Space Ranger Pete on an action-packed, colourful journey through space. Space Ranger Pete begins on Earth: the user navigates around a 'locker room' to learn about synthetic materials used in rocket boosters, heat shields, space suits and helmets, and how these materials have now become indispensable to everyday life. From Earth he flies into space and the user follows him from the control room in the spacecraft to a planet, satellites and finally to the International Space Station. Along the way, the user jots down clues that he or she discovers in this exploration, designing an imaginary space community and putting together a submission for the contest. The lucky winners will spend a weekend training as "junior astronauts" at the European Space Centre in Belgium (20-22 April 2001). They will be put through their astronaut paces, learning the art of space walking, running their own space mission, piloting a space capsule and re-entering the Earth's atmosphere. The competition features in various youth media channels across Europe. In the UK, popular BBC Saturday morning TV show, Live & Kicking, will be launching the competition and will invite viewers to submit their space community designs to win a weekend at ESC. In Germany, high circulation children's magazine Geolino will feature the competition in the January issue and on their internet site. And youth magazine ZoZitDat will feature the competition in the Netherlands throughout February. Space Mission: Y3K is part of an on-going partnership between the ESA's Technology Transfer

    Meaning of Web-page content plays a big role while produced a search result from a search engine. Most of the cases Web-page meaning stored in title or meta-tag area but those meanings do not always match with Web-page content. To overcome this situation we need to go through the Web-page content to identify the Web-page meaning. In such cases, where Webpage content holds dual meaning words that time it is really difficult to identify the meaning of the Web-page. In this paper, we are introdu...

    Piezoceramic actuators, presently used in commercial Braille displays, are limited by the material's relatively small strain and brittle nature. For this reason, it is a challenge to develop full page, compact, graphic Braille displays that are affordable. A newly developed material composed of P(VDF-TrFE-CFE) terpolymer blended with 5% P(VDF-CTFE) electrostrictive actuators exhibits large strains (~5% at 150V/μm), fast actuation (>5 mm/s), and has a relatively high elastic modulus (1.2 GPa). This material exhibits more than double the elastic energy density and a 50% higher modulus of the original electrostrictive terpolymer. Hence, the potential for viable actuators in compact, full page Braille displays is greater than ever, provided actuators can be manufactured reliably in quantity. This talk presents recent work in scaling production of such rolled actuators. Actuators extend .5 mm, are confined to the 2.5 mm grid spacing of conventional Braille text, generate >0.5 N force and operate at less than 200V, thus meeting the primary requirements for a commercialized Braille display. To manufacture these actuators, cast films are stretched using a roll-to-roll zone drawing machine that is capable of producing quantities of 2 μm thick film with high quality. What follows is a discussion of this machine, the roll-to-roll film stretching process and an assessment of the resulting stretched film for use as linear strain actuators, like those used in our Braille cell.

    In 2006, after a visual inspection of the Leonardo da Vinci's Atlantic Codex by a scholar, active molds were reported to have been present on Codex pages showing areas of staining. In the present paper, molecular methods were used to assess the current microbiological risk to stained pages of the manuscript. Bacterial and fungal communities were sampled by a non-invasive technique employing nitrocellulose membranes. Denaturing gradient gel electrophoresis of 16 S rRNA gene and internal transcribed space regions were carried out to study the structure of the bacterial and fungal communities and band patterns were analyzed by the multivariate technique of principal component analysis. Any relationship between the presence of an active microbial community and staining was excluded. The presence of potential biodeteriogens was evaluated by constructing bacterial and fungal clone libraries, analyzing them by an operational taxonomic unit (OTU) approach. Among the bacteria, some OTUs were associated with species found on floors in clean room while others were identified with human skin contamination. Some fungal OTU representatives were potential biodeteriogens that, under proper thermo-hygrometric conditions, could grow. The retrieval of these potential biodeteriogens and microorganisms related to human skin suggests the need for a continuous and rigorous monitoring of the environmental conditions, and the need to improve handling procedures.

    2013-03-01

    In this paper we consider the issue of advertising to children. Advertising to children raises a number of concerns, in particular the effects of food advertising on children's eating habits. We point out that virtually all the research into children's understanding of advertising has focused on traditional television advertisements, but much marketing aimed at children is now via the Internet and little is known about children's awareness of advertising on the Web. One important component of understanding advertisements is the ability to distinguish advertisements from other messages, and we suggest that young children's ability to recognise advertisements on a Web page is far behind their ability to recognise advertisements on television.

    The simplicity of producing and consuming online content makes it difficult to estimate how much attention will be devoted from Internet users to any given content. This work presents a general overview of temporal patterns in the access to content on a huge collaborative platform. We propose a model for predicting the popularity of promoted content, inspired by the analysis of the page-view dynamics on Wikipedia. Compared to previous studies, the observed popularity patterns are more complex; however, our model uses just few parameters to fully describe them. The model is validated through empirical measurements.

    2004-01-01

    Based on the two path metrics being equal at a merged node in the trellis employed to describe a Viterbi detector for the detection of data encoded with a rate 6∶8 balanced binary code in page-oriented optical memories, the combined Viterbi detector scheme is proposed to improve raw bit-error rate performance by mitigating the occurrence of a two-bit reversing error event in an estimated codeword for the balanced code. The effectiveness of the detection scheme is verified for different data quantizations using Monte Carlo simulations.

  1. PageRank for low frequency earthquake detection

    Science.gov (United States)

    Aguiar, A. C.; Beroza, G. C.

    2013-12-01

    We have analyzed Hi-Net seismic waveform data during the April 2006 tremor episode in the Nankai Trough in SW Japan using the autocorrelation approach of Brown et al. (2008), which detects low frequency earthquakes (LFEs) based on pair-wise waveform matching. We have generalized this to exploit the fact that waveforms may repeat multiple times, on more than just a pair-wise basis. We are working towards developing a sound statistical basis for event detection, but that is complicated by two factors. First, the statistical behavior of the autocorrelations varies between stations. Analyzing one station at a time assures that the detection threshold will only depend on the station being analyzed. Second, the positive detections do not satisfy "closure." That is, if window A correlates with window B, and window B correlates with window C, then window A and window C do not necessarily correlate with one another. We want to evaluate whether or not a linked set of windows are correlated due to chance. To do this, we map our problem on to one that has previously been solved for web search, and apply Google's PageRank algorithm. PageRank is the probability of a 'random surfer' to visit a particular web page; it assigns a ranking for a webpage based on the amount of links associated with that page. For windows of seismic data instead of webpages, the windows with high probabilities suggest likely LFE signals. Once identified, we stack the matched windows to improve the snr and use these stacks as template signals to find other LFEs within continuous data. We compare the results among stations and declare a detection if they are found in a statistically significant number of stations, based on multinomial statistics. We compare our detections using the single-station method to detections found by Shelly et al. (2007) for the April 2006 tremor sequence in Shikoku, Japan. We find strong similarity between the results, as well as many new detections that were not found using

    2010-06-01

    Rich-club and page-club coefficients and their null models are introduced for directed graphs. Null models allow for a quantitative discussion of the rich-club and page-club phenomena. These coefficients are computed for four directed real-world networks: Arxiv High Energy Physics paper citation network, Web network (released from Google), Citation network among US Patents, and email network from a EU research institution. The results show a high correlation between rich-club and page-club ordering. For journal paper citation network, we identify both rich-club and page-club ordering, showing that “elite” papers are cited by other “elite” papers. Google web network shows partial rich-club and page-club ordering up to some point and then a narrow declining of the corresponding normalized coefficients, indicating the lack of rich-club ordering and the lack of page-club ordering, i.e. high in-degree (PageRank) pages purposely avoid sharing links with other high in-degree (PageRank) pages. For UC patents citation network, we identify page-club and rich-club ordering providing a conclusion that “elite” patents are cited by other “elite” patents. Finally, for email communication network we show lack of both rich-club and page-club ordering. We construct an example of synthetic network showing page-club ordering and the lack of rich-club ordering.

  4. The Leggett-Garg inequality and Page-Wootters mechanism

    CERN Document Server

    Gangopadhyay, D

    2016-01-01

    Violation of the Leggett-Garg inequality (LGI) implies quantum phenomena. In this light we establish that the Moreva \\textit{et al.} \\cite{moreva} experiment demonstrating the Page-Wootter's mechanism \\cite{wootters} falls in the quantum domain. An observer outside a 2-photons world does not detect any change in the $2-$photons state,i.e. there is no time parameter for the outside observer. But an observer attached to one of the photons sees the other photon evolving and this means there is an "internal" time. The LGI is violated for the clock photon whose state evolves with the internal time as measured by the system photon. Conditional probabilities in this 2-photons system are computed for both sharp and unsharp measurements. The conditional probability increases for entangled states as obtained by Page and Wootters for both ideal and also unsharp measurements. We discuss how the conditional probabilities can be used to distinguish between massless and massive gravitons. This is important in the context of...

    Full Text Available The internethas massive amount of information. This information is stored in the form of zillions of webpages. The information that can be retrieved by search engines is huge, and this information constitutes the ‘surface web’.But the remaining information, which is not indexed by search engines – the ‘deep web’, is much bigger in size than the ‘surface web’, and remains unexploited yet. Several machine learning techniques have been commonly employed to access deep web content. Under machine learning, topic models provide a simple way to analyze large volumes of unlabeled text. A ‘topic’is a cluster of words that frequently occur together and topic models can connect words with similar meanings and distinguish between words with multiple meanings. In this paper, we cluster deep web databases employing several methods, and then perform a comparative study. In the first method, we apply Latent Semantic Analysis (LSA over the dataset. In the second method, we use a generative probabilistic model called Latent Dirichlet Allocation(LDA for modeling content representative of deep web databases.Both these techniques are implemented after preprocessing the set of web pages to extract page contents and form contents.Further, we propose another version of Latent Dirichlet Allocation (LDA to the dataset. Experimental results show that the proposed method outperforms the existing clustering methods.

    Permeability of dialysis membranes for high molecular weight compounds should be similar to that of the glomerular membrane in order to remove uremic toxins like the human kidney does. In order to evaluate permeability of high-flux dialysis membranes SDS-PAGE is applied for examination of filtrate of dialysers during routine dialysis with different membranes. SDS-PAGE analysis is performed with silver staining method according to the modification of Melzer (5) and consecutive laser densitometry. The protein pattern of filtrate from dialysis membranes is similar to that of the glomerular membrane containing IgG, transferrin, albumin, alpha-1-microglobulin, retinol binding protein and beta-2-microglobulin. Comparing different membranes there are considerable differences depending on cut-off, charge and adsorption capacity of the particular membrane. In all membranes tested permeability of proteins decreases during one treatment session. Protein permeability of high-flux dialysis membranes is similar to the gloemerular membrane but modified according to pore-size, surface charge, adsorption and time on dialysis. In contrast to the glomerular membrane in each of the investigated membranes protein permeability decreases during function.

    2011-01-01

    Full Text Available The World Wide Web is a distributed collection of web sites available on the Internet anywhere in the world. Its content is constantly changing: old data are being replaced which causes constant loss of a huge amount of information and consequently the loss of scientific, cultural and other heritage. Often, unnoticeably even legal certainty is questioned. In what way the data on the web can be stored and how to preserve them for the long term is a great challenge. Even though some good practices have been developed, the question of final solution on the national level still remains. The paper presents the problems of long-term preservation of web pages from technical and organizational point of view. It includes phases such as capturing and preserving web pages, focusing on good solutions, world practices and strategies to find solutions in this area developed by different countries. The paper suggests some conceptual steps that have to be defined in Slovenia which would serve as a framework for all document creators in the web environment and therefore contributes to the consciousness in this field, mitigating problems of all dealing with these issues today and in the future.

    2009-03-01

    Identifying what is, and what is not an advertisement is the first step in realizing that an advertisement is a marketing message. Children can distinguish television advertisements from programmes by about 5 years of age. Although previous researchers have investigated television advertising, little attention has been given to advertisements in other media, even though other media, especially the Internet, have become important channels of marketing to children. We showed children printed copies of invented web pages that included advertisements, half of which had price information, and asked the children to point to whatever they thought was an advertisement. In two experiments we tested a total of 401 children, aged 6, 8, 10 and 12 years of age, from the United Kingdom and Indonesia. Six-year-olds recognized a quarter of the advertisements, 8-year-olds recognized half the advertisements, and the 10- and 12-year-olds recognized about three-quarters. Only the 10- and 12-year-olds were more likely to identify an advertisement when it included a price. We contrast our findings with previous results about the identification of television advertising, and discuss why children were poorer at recognizing web page advertisements. The performance of the children has implications for theories about how children develop an understanding of advertising.

    Stühmer, Roland; Anicic, Darko; Sen, Sinan; Ma, Jun; Schmidt, Kay-Uwe; Stojanovic, Nenad

    In this paper we present a method and an implementation for creating and processing semantic events from interaction with Web pages which opens possibilities to build event-driven applications for the (Semantic) Web. Events, simple or complex, are models for things that happen e.g., when a user interacts with a Web page. Events are consumed in some meaningful way e.g., for monitoring reasons or to trigger actions such as responses. In order for receiving parties to understand events e.g., comprehend what has led to an event, we propose a general event schema using RDFS. In this schema we cover the composition of complex events and event-to-event relationships. These events can then be used to route semantic information about an occurrence to different recipients helping in making the Semantic Web active. Additionally, we present an architecture for detecting and composing events in Web clients. For the contents of events we show a way of how they are enriched with semantic information about the context in which they occurred. The paper is presented in conjunction with the use case of Semantic Advertising, which extends traditional clickstream analysis by introducing semantic short-term profiling, enabling discovery of the current interest of a Web user and therefore supporting advertisement providers in responding with more relevant advertisements.

  10. Appraisals of Salient Visual Elements in Web Page Design

    2016-01-01

    Full Text Available Visual elements in user interfaces elicit emotions in users and are, therefore, essential to users interacting with different software. Although there is research on the relationship between emotional experience and visual user interface design, the focus has been on the overall visual impression and not on visual elements. Additionally, often in a software development process, programming and general usability guidelines are considered as the most important parts of the process. Therefore, knowledge of programmers’ appraisals of visual elements can be utilized to understand the web page designs we interact with. In this study, appraisal theory of emotion is utilized to elaborate the relationship of emotional experience and visual elements from programmers’ perspective. Participants (N=50 used 3E-templates to express their visual and emotional experiences of web page designs. Content analysis of textual data illustrates how emotional experiences are elicited by salient visual elements. Eight hierarchical visual element categories were found and connected to various emotions, such as frustration, boredom, and calmness, via relational emotion themes. The emotional emphasis was on centered, symmetrical, and balanced composition, which was experienced as pleasant and calming. The results benefit user-centered visual interface design and researchers of visual aesthetics in human-computer interaction.

    2006-03-20

    In the present study, an alternative procedure for two-dimensional (2D) electrophoretic analysis in proteomic investigation of the most represented basic muscle water-soluble proteins is suggested. Our method consists of Acetic acid-Urea-Triton polyacrylamide gel (AUT-PAGE) analysis in the first dimension and standard sodium dodecyl sulphate polyacrylamide gel (SDS-PAGE) in the second dimension. Although standard two-dimensional Immobilized pH Gradient-Sodium Dodecyl-Sulphate (2D IPG-SDS) gel electrophoresis has been successfully used to study these proteins, most of the water-soluble proteins are spread on the alkaline part of the 2D map and are poorly focused. Furthermore, the similarity in their molecular weights impairs resolution of the classical approach. The addition of Triton X-100, a non-ionic detergent, into the gel induces a differential electrophoretic mobility of proteins as a result of the formation of mixed micelles between the detergent and the hydrophobic moieties of polypeptides, separating basic proteins with a criterion similar to reversed phase chromatography based on their hydrophobicity. The acid pH induces positive net charges, increasing with the isoelectric point of proteins, thus allowing enhanced resolution in the separation. By using 2D AUT-PAGE/SDS electrophoresis approach to separate water-soluble proteins from fresh pork and from dry-cured products, we could spread proteins over a greater area, achieving a greater resolution than that obtained by IPG in the pH range 3-10 and 6-11. Sarcoplasmic proteins undergoing proteolysis during the ripening of products were identified by Matrix Assisted Laser Desorption/Ionization-Time of Flight (MALDI-ToF) mass spectrometry peptide mass fingerprinting in a easier and more effective way. Two-dimensional AUT-PAGE/SDS electrophoresis has allowed to simplify separation of sarcoplasmic protein mixtures making this technique suitable in the defining of quality of dry-cured pork products by immediate

    Full Text Available Wheat storage proteins accounted for up to 60% of the total grain proteins. They form gluten proteins, which make a visco-elastic network enables dough to be processed into bread, pasta and other products. In order to study genetic variation of wild wheat relatives, electrophoretic patterns of seed storage proteins, the high-molecular-weight glutenins and gliadins from about 12 wild species and some check improved cultivars were fractionated by SDS-PAGE and Acid-PAGE. The results showed some close relationship between T. urartu, T. dicoccum and bread wheat in the case of glutenin and gliadin. Therefore It was speculated that progenitor of A genome of cultivated wheat could be T. urartu strongly. A high level of polymorphism was detected in the glutenin and gliadin subunits of the wild wheat relatives, showing some similarities with cultivated bread wheat, useful breeding perspectives. The electrophoresis proved to be a suitable method to discriminate wheat variety and species. Also results of this study confirmed that the genetic variation amongst seed storage proteins of wild relatives were considerable. The wild progenitors are important genetic resources and therefore observed genetic variability could be use in any selection strategies.

Simultaneously, work in the areas of social bookmarking, social news, and subscription-based technologies have been taking the existence, usage, and utility of this data for granted with neither investigation into what people are doing with their collections nor how they are trying to maintain them. In order to address these concerns, we performed an online user study of 125 individuals from a variety of online and offline communities, such as the reddit social news user community and the graduate student body in our department. From this study we were able to examine a user's needs for a system to manage their web-based distributed collections, how their current tools affect their ability to maintain their collections, and what the characteristics of their current practices ...

    Today, more than ever, knowledge that interfaces appearance analysis is a crucial point in human-computer interaction field has been accepted. As nowadays virtually anyone can publish information on the web, the credibility role has grown increasingly important in relation to the web-based content. Areas like trust, credibility, and behavior, doubled by overall impression and user expectation are today in the spotlight of research compared to the last period, when other pragmatic areas such as usability and utility were considered. Credibility has been discussed as a theoretical construct in the field of communication in the past decades and revealed that people tend to evaluate the credibility of communication primarily by the communicator's expertise. Other factors involved in the content communication process are trustworthiness and dynamism as well as various other criteria but to a lower extent. In this brief review, factors like web page aesthetics, browsing experiences and user experience are considered.

    Full Text Available Social network greatly improve the social recommendation application, especially the study of group recommendation. The group recommendation, analyze the social factors of the group, such as social and trust relationship between users, as the factors for the prediction model established. In this paper, PageRank algorithm is introduced in the recommendation method to calculate the member’s importance in the group respectively, and to amend the aggregate function of individual preferences. The aggregate function consider the relationship between various users in the group, and optimize the aggregate function according to users different influence on the group, which can better reflect the social characteristics of group. In short, the study on group recommended model and algorithm can take the initiative to find the user's needs. Extensive experiments demonstrate the effectiveness and efficiency of the methods, which improve the prediction accuracy of the group recommended algorithms.

  3. Semantic Web Techniques for Yellow Page Service Providers

    Directory of Open Access Journals (Sweden)

    Raghu Anantharangachar

    2012-08-01

    Full Text Available Applications providing “yellow pages information” for use over the web should ideally be based on structured information. Use of web pages providing unstructured information poses variety of problems to the user, such as use of arbitrary formats, unsuitability for machine processing and likely incompleteness of information. Structured data alleviates these problems but we require more. Capturing the semantics of a domain in the form of an ontology is necessary to ensure that unforeseen application can easily be created at a later date. Very often yellow page systems are implemented using a centralized database. In some cases, human intermediaries accessible over the phone network examine a centralized database and use their reasoning ability to deal with the user’s need for information. Centralized operation and considerable central administration make these systems expensive to operate. Scaling up such systems is difficult. They behave like isolated systems and it is common for such systems to be highly domain specific, for instance systems dealing with accommodation and travel. This paper explores an alternative – a highly distributed system design meeting a variety of needs – considerably reducing efforts required at a central organization, enabling large numbers of vendors to enter information about their own products and services, enablingend-users to contribute information such as their own ratings, using an ontology to describe each domain of application in a flexible manner for uses foreseen and unforeseen, enabling distributed search and mashups, use of vendor independent standards, using reasoning to find the best matches to a given query, geospatial reasoning and a simple, interactive, mobile application/interface. We view this design as one in which vendors and end-users do the bulk of the work in building large distributed collections of information in a Web 2.0 style. We give importance to geo-spatial information and

  4. Hawking–Page phase transition in new massive gravity

    2015-07-01

    Full Text Available We consider Hawking–Page phase transition between the BTZ black hole with M≥0 and the thermal soliton with M=−1 in new massive gravity. By comparing the on-shell free energies, we can see that there exists a critical temperature. The thermal soliton is more probable than the black hole below the critical temperature while the black hole is more probable than the thermal soliton above the critical temperature. By consistently constructing the off-shell free energies taking into account the conical singularity, we show that there exist infinite non-equilibrium states connecting the BTZ black hole and the thermal soliton, so that they provide a picture of continuous evolution of the phase transition.

  5. Improving PageRank for Local Community Detection

    CERN Document Server

    Hollocou, Alexandre; Bonald, Thomas

    2016-01-01

    Community detection is a classical problem in the field of graph mining. While most algorithms work on the entire graph, it is often interesting in practice to recover only the community containing some given set of seed nodes. In this paper, we propose a novel approach to this problem, using some low-dimensional embedding of the graph based on random walks starting from the seed nodes. From this embedding, we propose some simple yet efficient versions of the PageRank algorithm as well as a novel algorithm, called WalkSCAN, that is able to detect multiple communities, possibly overlapping. We provide insights into the performance of these algorithms through the theoretical analysis of a toy network and show that WalkSCAN outperforms existing algorithms on real networks.

    Britt, M Anne; Gabrys, Gareth

    2004-02-01

    This article describes how to collect responses from experimental participants using drag and drop on a Web page. In particular, we describe how drag and drop can be used in a text search task in which participants read a text and then locate and categorize certain elements of the text (e.g., to identify the main claim of a persuasive paragraph). Using this technique, participants respond by clicking on a text segment and dragging it to a screen field or icon. We have successfully used this technique in both the argument element identification experiment that we describe here and a tutoring system that we created to teach students to identify source characteristics while reading historical texts (Britt, Perfetti, Van Dyke, & Gabrys, 2000). The implementation described here exploits the capability of recent versions of Microsoft's Internet Explorer Web browser to handle embedded XML documents and drag and drop events.

  7. Learning Hierarchical User Interest Models from Web Pages

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    We propose an algorithm for learning hierarchical user interest models according to the Web pages users have browsed. In this algorithm, the interests of a user are represented into a tree which is called a user interest tree, the content and the structure of which can change simultaneously to adapt to the changes in a user's interests. This expression represents a user's specific and general interests as a continuum. In some sense, specific interests correspond to short-term interests, while general interests correspond to long-term interests. So this representation more really reflects the users' interests. The algorithm can automatically model a user's multiple interest domains, dynamically generate the interest models and prune a user interest tree when the number of the nodes in it exceeds given value. Finally, we show the experiment results in a Chinese Web Site.

    2013-03-28

    The evolving Web has seen ever-growing use of structured data, thanks to the way it enhances information authoring, querying, visualization and sharing. To date, however, most structured data authoring and management tools have been oriented towards programmers and Web developers. End users have been left behind, unable to leverage structured data for information management and communication as well as professionals. In this paper, I will argue that many of the benefits of structured data management can be provided to end users as well. I will describe an approach and tools that allow end users to define their own schemas (without knowing what a schema is), manage data and author (not program) interactive Web visualizations of that data using the Web tools with which they are already familiar, such as plain Web pages, blogs, wikis and WYSIWYG document editors. I will describe our experience deploying these tools and some lessons relevant to their future evolution.

    O'Donovan, Peter; Agarwala, Aseem; Hertzmann, Aaron

    2014-08-01

    This paper presents an approach for automatically creating graphic design layouts using a new energy-based model derived from design principles. The model includes several new algorithms for analyzing graphic designs, including the prediction of perceived importance, alignment detection, and hierarchical segmentation. Given the model, we use optimization to synthesize new layouts for a variety of single-page graphic designs. Model parameters are learned with Nonlinear Inverse Optimization (NIO) from a small number of example layouts. To demonstrate our approach, we show results for applications including generating design layouts in various styles, retargeting designs to new sizes, and improving existing designs. We also compare our automatic results with designs created using crowdsourcing and show that our approach performs slightly better than novice designers.

  11. PAGES-Powell North America 2k database

    McKay, N.

    2014-12-01

    Syntheses of paleoclimate data in North America are essential for understanding long-term spatiotemporal variability in climate and for properly assessing risk on decadal and longer timescales. Existing reconstructions of the past 2,000 years rely almost exclusively on tree-ring records, which can underestimate low-frequency variability and rarely extend beyond the last millennium. Meanwhile, many records from the full spectrum of paleoclimate archives are available and hold the potential of enhancing our understanding of past climate across North America over the past 2000 years. The second phase of the Past Global Changes (PAGES) North America 2k project began in 2014, with a primary goal of assembling these disparate paleoclimate records into a unified database. This effort is currently supported by the USGS Powell Center together with PAGES. Its success requires grassroots support from the community of researchers developing and interpreting paleoclimatic evidence relevant to the past 2000 years. Most likely, fewer than half of the published records appropriate for this database are publicly archived, and far fewer include the data needed to quantify geochronologic uncertainty, or to concisely describe how best to interpret the data in context of a large-scale paleoclimatic synthesis. The current version of the database includes records that (1) have been published in a peer-reviewed journal (including evidence of the record's relationship to climate), (2) cover a substantial portion of the past 2000 yr (>300 yr for annual records, >500 yr for lower frequency records) at relatively high resolution (identify and assimilate relevant records that have not yet been included. The goal is to develop a comprehensive and open-access resource that will serve the diverse community interested in the climate of the Common Era in North America.

    The purpose of this study is to assess the utility of CT paging arteriography with a multidetector-row CT as a replacement for conventional angiography in the evaluation of splanchnic arterial anomalies. Sixty-three patients underwent CT paging arteriography with a multidetector-row CT. In the 56 patients with conventional angiographic correlation, there was only one minor disagreement with CT paging arteriography. In the 7 patients who underwent IVDSA (intra venous digital subtraction angiography), CT paging arteriography defined four hepatic arterial anomalies which could not be depicted by IVDSA. In conclusion, CT paging arteriography provides noninvasive means to identify splanchnic arterial anomalies. (author)

    2012-01-01

    Nowadays, there is a problem in most meta-search engines that many web pages searched have nothing to do with users' expectations. We introduce a new user web page interactive model under the framework ofmeta search, which analyzes users' action to get users' interests and storages them, and update these information with users' feedback. Meanwhile this model analyzes user records stored in web, attaches labels to the web page with statistics of user interest. We calculate the similarity about user and web page with the information from model and add similarity to scores of web pages. The experimental results reveal that this method can improve the relevance of the information retrieval.

    2002-01-01

    The World Wide Web is increasingly important for medical education. Internet served pages may also be used on a local hard disk or CD-ROM without a network or server. This allows authors to reuse existing content and provide access to users without a network connection. CD-ROM offers several advantages over network delivery of Web pages for several applications. However, creating Web pages for CD-ROM requires careful planning. Issues include file names, relative links, directory names, default pages, server created content, image maps, other file types and embedded programming. With care, it is possible to create server based pages that can be copied directly to CD-ROM. In addition, Web pages on CD-ROM may reference Internet served pages to provide the best features of both methods.

    2015-04-01

    This article examines the use of six Danish "Rest in Peace" or (RIP) memorial pages. The article focuses on the relation between news media and RIP page use, in relation to general communicative practices on these pages. Based on an analysis of press coverage of the deaths of six young people and a close analysis of 1,015 comments extracted from the RIP pages created to memorialize them, it is shown that their deaths attracted considerable media attention, as did the RIP pages themselves. Comment activity seem to reflect the news stories in the way the commenters refer to the context of death and the emotional distress they experience, but mainly comments on the RIP pages are conventional expressions of sympathy and "RIP" wishes. The article concludes that public RIP pages might be understood as virtual spontaneous shrines, affording an emerging practice of "RIP-ing."

    Nath, Rajender; Kumar, Naresh

    2011-12-01

    Search Engine gives an ordered list of web search results in response to a user query, wherein the important pages are usually displayed at the top with less important ones afterwards. It may be possible that the user may have to look for many screen results to get the required documents. In literatures, many page ranking algorithms has been given to find the page rank of a page. For example PageRank is considered in this work. This algorithm treats all the links equally when distributing rank scores. That's why this algorithm some time gives equal importance to all the pages. But in real this can not be happen because, if two pages have same rank then how we can judge which page is more important then other. So this paper proposes another idea to organize the search results and describe which page is more important when confliction of same rank is produced by the PageRank. So that the user can get more relevant and important results easily and in a short span of time.

    2011-01-01

    Rich-club and page-club coefficients and their null models are introduced for directed graphs. Null models allow for a quantitative discussion of the rich-club and page-club phenomena. These coefficients are computed for four directed real-world networks: Arxiv High Energy Physics paper citation network, Web network (released from Google), Citation network among US Patents, and Email network from a EU research institution. The results show a high correlation between rich-club and page-club ordering. For journal paper citation network, we identify both rich-club and page-club ordering, showing that {}"elite" papers are cited by other {}"elite" papers. Google web network shows partial rich-club and page-club ordering up to some point and then a narrow declining of the corresponding normalized coefficients, indicating the lack of rich-club ordering and the lack of page-club ordering, i.e. high in-degree (PageRank) pages purposely avoid sharing links with other high in-degree (PageRank) pages.

    Visual layout has a strong impact on performance and is a critical factor in the design of graphical user interfaces (GUIs) and Web pages. Many design guidelines employed in Web page design were inherited from human performance literature and GUI design studies and practices. However, few studies have investigated the more specific patterns of performance with Web pages that may reflect some differences between Web page and GUI design. We investigated interactions among four visual layout factors in Web page design (quantity of links, alignment, grouping indications, and density) in two experiments: one with pages in Hebrew, entailing right-to-left reading, and the other with English pages, entailing left-to-right reading. Some performance patterns (measured by search times and eye movements) were similar between languages. Performance was particularly poor in pages with many links and variable densities, but it improved with the presence of uniform density. Alignment was not shown to be a performance-enhancing factor. The findings are discussed in terms of the similarities and differences in the impact of layout factors between GUIs and Web pages. Actual or potential applications of this research include specific guidelines for Web page design.

  3. AUTOMATIC TAGGING OF PERSIAN WEB PAGES BASED ON N-GRAM LANGUAGE MODELS USING MAPREDUCE

    Directory of Open Access Journals (Sweden)

    Saeed Shahrivari

    2015-07-01

    Full Text Available Page tagging is one of the most important facilities for increasing the accuracy of information retrieval in the web. Tags are simple pieces of data that usually consist of one or several words, and briefly describe a page. Tags provide useful information about a page and can be used for boosting the accuracy of searching, document clustering, and result grouping. The most accurate solution to page tagging is using human experts. However, when the number of pages is large, humans cannot be used, and some automatic solutions should be used instead. We propose a solution called PerTag which can automatically tag a set of Persian web pages. PerTag is based on n-gram models and uses the tf-idf method plus some effective Persian language rules to select proper tags for each web page. Since our target is huge sets of web pages, PerTag is built on top of the MapReduce distributed computing framework. We used a set of more than 500 million Persian web pages during our experiments, and extracted tags for each page using a cluster of 40 machines. The experimental results show that PerTag is both fast and accurate

    Document analysis tasks, as text recognition, word spotting, or segmentation, are highly dependent on comprehensive and suitable databases for training and validation. However their generation is expensive in sense of labor and time. As a matter of fact, there is a lack of such databases, which complicates research and development. This is especially true for the case of Arabic handwriting recognition, that involves different preprocessing, segmentation, and recognition methods, which have individual demands on samples and ground truth. To bypass this problem, we present an efficient system that automatically turns Arabic Unicode text into synthetic images of handwritten documents and detailed ground truth. Active Shape Models (ASMs) based on 28046 online samples were used for character synthesis and statistical properties were extracted from the IESK-arDB database to simulate baselines and word slant or skew. In the synthesis step ASM based representations are composed to words and text pages, smoothed by B-Spline interpolation and rendered considering writing speed and pen characteristics. Finally, we use the synthetic data to validate a segmentation method. An experimental comparison with the IESK-arDB database encourages to train and test document analysis related methods on synthetic samples, whenever no sufficient natural ground truthed data is available.

    Full Text Available As e-commerce is gaining popularity day by day, the web has become an excellent source for gathering customer reviews / opinions by the market researchers. The number of customer reviews that a product receives is growing at very fast rate (It could be in hundreds or thousands. Customer reviews posted on the websites vary greatly in quality. The potential customer has to read necessarily all the reviews irrespective of their quality to make a decision on whether to purchase the product or not. In this paper, we make an attempt to assess are view based on its quality, to help the customer make a proper buying decision. The quality of customer review is assessed as most significant, more significant, significant and insignificant.A novel and effective web mining technique is proposed for assessing a customer review of a particular product based on the feature clustering techniques, namely, k-means method and fuzzy c-means method. This is performed in three steps : (1Identify review regions and extract reviews from it, (2 Extract and cluster the features of reviews by a clustering technique and then assign weights to the features belonging to each of the clusters (groups and (3 Assess the review by considering the feature weights and group belongingness. The k-means and fuzzy c-means clustering techniques are implemented and tested on customer reviews extracted from web pages. Performance of these techniques are analyzed.

  6. Analyzing Web pages visual scanpaths: between and within tasks variability.

    Drusch, Gautier; Bastien, J M Christian

    2012-01-01

    In this paper, we propose a new method for comparing scanpaths in a bottom-up approach, and a test of the scanpath theory. To do so, we conducted a laboratory experiment in which 113 participants were invited to accomplish a set of tasks on two different websites. For each site, they had to perform two tasks that had to be repeated ounce. The data were analyzed using a procedure similar to the one used by Duchowski et al. [8]. The first step was to automatically identify, then label, AOIs with the mean-shift clustering procedure [19]. Then, scanpaths were compared two by two with a modified version of the string-edit method, which take into account the order of AOIs visualizations [2]. Our results show that scanpaths variability between tasks but within participants seems to be lower than the variability within task for a given participant. In other words participants seem to be more coherent when they perform different tasks, than when they repeat the same tasks. In addition, participants view more of the same AOI when they perform a different task on the same Web page than when they repeated the same task. These results are quite different from what predicts the scanpath theory.

    The emergence of distributed Web crawl largely expands the scale of related Web information. Since PageRank needs to process the topology of entire existed page set, the limitation of CPU, I/O and memory becomes the big issue when it confronts the data in TB or PB level. Aiming at these problems, this paper proposes a parallel PageRank algorithm based on MapReduce. In a certain iteration of algorithm, it processes the files containing the topology of Web page graph by Map function and calculates the pages’ scores by Reduce function. Using the global Web page score as convergence to control iterations and get more precise Web page sorting result. Experimental result shows that the improved algorithm has better clustering performance and faster execution speed on the basis of keeping the overall Web page sorting accuracy of single machine PageRank algorithm.%分布式网络爬虫的广泛应用使得搜索引擎的数据规模呈几何式增长,面对数以 TB 甚至 PB 量级的数据,单机模式下的PageRank 算法由于 CPU、I/O 和内存的开销过大导致效率低下。为此,提出一种基于 MapReduce 框架的并行 PageRank 算法。在算法的一次迭代过程中,利用 Map 函数对网页拓扑信息文件进行解析,使用 Reduce 函数计算网页得分,从而并行化 PageRank 算法的中间迭代过程。通过计算全局网页得分控制迭代次数,得到较精确的网页排序结果。实验结果表明,该算法在保持原有单机PageRank 算法整体网页排序精度的基础上,具有较好的集群性能和较快的执行速度。

  9. Detection of Molecular Weight of PMCA Isoform with 20 cm SDS PAGE Electrophoresis:Compared with 8 cm SDS PAGE

    2005-01-01

    Purpose: To compare the effect of 20 cm SDS-PAGE electrophoresis, which is most widely used in proteomic research, in identifying human lens epithelium B3 (HLE B3) cells plasma membrane calcium ATPase (PMCA) isoform's apparent molecular weight (MW), with that of 8 cm SDS-PAGE electrophoresis.Method: HLE B-3 cells were cultured and membrane protein sample was collected. Part of the sample is electrophoresised with 20 cm gel, 16 mA/gel for 1.5 hrs and then 24 mA/gel for 4~5 hrs. The same sample is electrophoresised with 8cm mini gel, 200V for 2 hrs. Protein marker of known MW was run with the sample in the same gel. The resulting separated proteins were transferred to polyvinylidene difluoride (PVDF) membrane and Western blot were used to identify the PMCA isoform with specific antibody against PMCA 1, 2, 4. The apparent MW was calculated in reference to the known protein marker that was electrophoresised in the same gel.Result: In 8 cm gel the distance between 208 kDa and 126 kDa band was about 6.1 mm,while that of 20 cm gel was 32.8 mm. The distance between 126 kDa and 97 kDa was about 5.2 mm, while that of 20 cm gel was 20.2 mm. The migration distance differences of protein bands were significantly much longer in 20 cm gel than in 8 cm gel (P < 0.005).But the bands were generally more condensed in 8 cm gel. The apparent MW of PMCA1,2, 4 were 153.8, 153.5 and 152.9 kDa respectively. In the 20 cm gel, the apparent MW for PMCA1, 2, 4 was 153.1, 125.5 and 147.4 kDa respectively.Conclusion: Both the 20 cm gel and 8 cm gel successful identified PMCA 1,2, 4 in HLE B-3 cells. The apparent MW for PMCA1, 2, 4 was 153.8, 153.5 and 152.9 kDa respectively in 8 cm gel,and 153.1,125.5 and 147.4 kDa respectively in 20 cm gel.PMCA2 probably had some kinds of degradation during the long electrophoresis time in 20 cm gel.

  10. Segmentation Based Approach to Dynamic Page Construction from Search Engine Results

    Kuppusamy, K S

    2012-01-01

    The results rendered by the search engines are mostly a linear snippet list. With the prolific increase in the dynamism of web pages there is a need for enhanced result lists from search engines in order to cope-up with the expectations of the users. This paper proposes a model for dynamic construction of a resultant page from various results fetched by the search engine, based on the web page segmentation approach. With the incorporation of personalization through user profile during the candidate segment selection, the enriched resultant page is constructed. The benefits of this approach include instant, one-shot navigation to relevant portions from various result items, in contrast to a linear page-by-page visit approach. The experiments conducted on the prototype model with various levels of users, quantifies the improvements in terms of amount of relevant information fetched.

  11. Calculating PageRank in a changing network with added or removed edges

    Engström, Christopher; Silvestrov, Sergei

    2017-01-01

    PageRank was initially developed by S. Brinn and L. Page in 1998 to rank homepages on the Internet using the stationary distribution of a Markov chain created using the web graph. Due to the large size of the web graph and many other real world networks fast methods to calculate PageRank is needed and even if the original way of calculating PageRank using a Power iterations is rather fast, many other approaches have been made to improve the speed further. In this paper we will consider the problem of recalculating PageRank of a changing network where the PageRank of a previous version of the network is known. In particular we will consider the special case of adding or removing edges to a single vertex in the graph or graph component.

    2006-01-01

    The content of personal Web home pages created by adolescents with cancer is a new source of information about this population of potential benefit to oncology nurses and psychologists. Individual Internet elements found on 21 home pages created by youths with cancer (14-22 years old) were rated for cancer-related self-presentation, information dissemination, and interpersonal connection. Examples of adolescents' online narratives were also recorded. Adolescents with cancer used various Internet elements on their home pages for cancer-related self-presentation (eg, welcome messages, essays, personal history and diary pages, news articles, and poetry), information dissemination (e.g., through personal interest pages, multimedia presentations, lists, charts, and hyperlinks), and interpersonal connection (eg, guestbook entries). Results suggest that various elements found on personal home pages are being used by a limited number of young patients with cancer for self-expression, information access, and contact with peers.

  15. Measuring consistency of web page design and its effects on performance and satisfaction.

    Ozok, A A; Salvendy, G

    2000-04-01

    This study examines the methods for measuring the consistency levels of web pages and the effect of consistency on the performance and satisfaction of the world-wide web (WWW) user. For clarification, a home page is referred to as a single page that is the default page of a web site on the WWW. A web page refers to a single screen that indicates a specific address on the WWW. This study has tested a series of web pages that were mostly hyperlinked. Therefore, the term 'web page' has been adopted for the nomenclature while referring to the objects of which the features were tested. It was hypothesized that participants would perform better and be more satisfied using web pages that have consistent rather than inconsistent interface design; that the overall consistency level of an interface design would significantly correlate with the three elements of consistency, physical, communicational and conceptual consistency; and that physical and communicational consistencies would interact with each other. The hypotheses were tested in a four-group, between-subject design, with 10 participants in each group. The results partially support the hypothesis regarding error rate, but not regarding satisfaction and performance time. The results also support the hypothesis that each of the three elements of consistency significantly contribute to the overall consistency of a web page, and that physical and communicational consistencies interact with each other, while conceptual consistency does not interact with them.

    Holden, Alexander C L; Spallek, Heiko

    2017-09-22

    The National Law that regulates the dental and other healthcare professions in Australia sets out regulations that dictate how dental practices are to advertise. This study examines the extent to which the profession complies with these regulations and the potential impact that advertising may have upon professionalism. A Facebook search of 38 Local Government Areas in Sydney, New South Wales was carried out to identify dental practices that had pages on this social media site. A framework for assessment of compliance was developed using the regulatory guidelines and was used to conduct a netnographic review. 266 practice pages were identified from across the 38 regions. 71.05% of pages were in breach of the National Law in their use of testimonials, 5.26% of pages displayed misleading or false information, 4.14% of pages displayed offers that had no clear terms and conditions or had inexact pricing, 19.55% of pages had pictures or text that was likely to create unrealistic expectations of treatment benefit and 16.92% of pages encouraged the indiscriminate and unnecessary utilisation of health services. This study found that compliance to the National Law by the Facebook pages surveyed was poor. This article is protected by copyright. All rights reserved. This article is protected by copyright.

However, the performance of the current focused crawling can easily suffer the impact of the environments of web pages and multiple topic web pages. In the crawling process, a highly relevant region may be ignored owing to the low overall relevance of that page, and anchor text or link-context may misguide crawlers. In order to solve these problems, this paper proposes a new focused crawler. First, we build a web page classifier based on improved term weighting approach (ITFIDF, in order to gain highly relevant web pages. In addition, this paper introduces an evaluation approach of the link, link priority evaluation (LPE, which combines web page content block partition algorithm and the strategy of joint feature evaluation (JFE, to better judge the relevance between URLs on the web page and the given topic. The experimental results demonstrate that the classifier using ITFIDF outperforms TFIDF, and our focused crawler is superior to other focused crawlers based on breadth-first, best-first, anchor text only, link-context only, and content block partition in terms of harvest rate and target recall. In conclusion, our methods are significant and effective for focused crawler.

    2016-02-01

    Web spam is a technique through which the irrelevant pages get higher rank than relevant pages in the search engine’s results. Spam pages are generally insufficient and inappropriate results for user. Many researchers are working in this area to detect the spam pages. However, there is no universal efficient technique developed so far which can detect all spam pages. This paper is an effort in that direction, where we propose a combined approach of content and link-based techniques to identify the spam pages. The content-based approach uses term density and Part of Speech (POS) ratio test and in the link-based approach, we explore the collaborative detection using personalized page ranking to classify the Web page as spam or non-spam. For experimental purpose, WEBSPAM-UK2006 dataset has been used. The results have been compared with some of the existing approaches. A good and promising F-measure of 75.2% demonstrates the applicability and efficiency of our approach.

Search engine visitors have a variety of impact on page views which cannot be described by single regression. On one hand referral visitors are well-fitted on linear regression with low impact. On the other hand, direct visitors made a huge impact on page views. The higher connection speed does not simply imply higher impact on page views and the content of web page and the territory of visitors can help connection speed to describe user behavior.Returning visitors have some similarities with direct visitors.

Ninety web pages were chosen by searching general search engines (Google, Yahoo and MSN. The scope of metadata elements (Dublin Core and HTML Meta tags present in these pages as well as existence of a significant correlation between presence of meta elements and type of search engines were investigated. Findings indicated very low presence of both Dublin Core metadata elements and HTML meta tags in the pages retrieved which in turn illustrates the very low usage of meta data elements in web pages. Furthermore, findings indicated that there are no significant correlation between the type of search engine used and presence of metadata elements. From the standpoint of including metadata in retrieval of web sources, search engines do not significantly differ from one another.

    Full Text Available Search engine optimization (SEO techniques involve „on-page“ and „off-page“ actions taken by web developers and SEO specialists with aim to increase the ranking of web pages in search engine results pages (SERP by following recommendations from major search engine companies. In this paper we explore the possibility of creating a metric for evaluating on-page SEO of a website. A novel „k-rank“ metric is proposed which takes into account not only the presence of certain tags in HTML of a page, but how those tags are used with selected keywords in selected domain. The „k-rank“ is tested in domain of education by inspecting 20 university websites and comparing them with expert scores. The overview of results showed that „k-rank“ can be used as a metric for on-page SEO.

    2011-10-01

    Social network sites enable users to express themselves, establish ties, and develop and maintain social relationships. Recently, many companies have begun using social media identity (e.g., Facebook fan pages) to enhance brand attractiveness, and social network sites have evolved into social utility networks, thereby creating a number of promising business opportunities. To this end, the operators of fan pages need to be aware of the factors motivating users to continue their patronization of such pages. This study set out to identify these motivating factors from the point of view of social capital. This study employed structural equation modeling to investigate a research model based on a survey of 327 fan pages users. This study discovered that ties related to social interaction (structural dimension), shared values (cognitive dimension), and trust (relational dimension) play important roles in users' continued intention to use Facebook fan pages. Finally, this study discusses the implications of these findings and offers directions for future research.

    There are huge amounts of information on Web pages, which includes content information and other useless information, such as navigation, advertisement and flash of animation etc. Reducing the toils of Web users, we estabished a thechnique to extract the content information from web page. Fristly, we analyzed the semantic of web documents by V8 engine of Google and parsed the web document into DOM tree. And then, traversed the DOM tree, pruned the DOM tree in the light of the characteristic of Web page's edit language. Finally, we extracted the content information from Web page. Theoretics and experiments showed that the technique could simplify the web page, present the content information to web users and supply clean data for applicable area, such as retrieval, KDD and DM from web.

    2011-03-01

    Full Text Available The results rendered by the search engines are mostly a linear snippet list. With the prolific increase in the dynamism of web pages there is a need for enhanced result lists from search engines inorder to cope-up with the expectations of the users. This paper proposes a model for dynamic construction of a resultant page from various results fetched by the search engine, based on the web pagesegmentation approach. With the incorporation of personalization through user profile during the candidate segment selection, the enriched resultant page is constructed. The benefits of this approachinclude instant, one-shot navigation to relevant portions from various result items, in contrast to a linear page-by-page visit approach. The experiments conducted on the prototype model with various levels of users, quantifies the improvements in terms of amount of relevant information fetched.

    2011-01-01

    This paper develops a flexible methodology to analyze the effectiveness of different variables on various dependent variables which all are times series and especially shows how to use a time series regression on one of the most important and primary index (page views per visit) on Google analytic and in conjunction it shows how to use the most suitable data to gain a more accurate result. Search engine visitors have a variety of impact on page views which cannot be described by single regression. On one hand referral visitors are well-fitted on linear regression with low impact. On the other hand, direct visitors made a huge impact on page views. The higher connection speed does not simply imply higher impact on page views and the content of web page and the territory of visitors can help connection speed to describe user behavior. Returning visitors have some similarities with direct visitors.

    Diedenhofen, Birk; Musch, Jochen

    2016-08-29

    Cheating threatens the validity of unproctored online achievement tests. To address this problem, we developed PageFocus, a JavaScript that detects when participants abandon test pages by switching to another window or browser tab. In a first study, we aimed at testing whether PageFocus could detect and prevent cheating. We asked 115 lab and 186 online participants to complete a knowledge test comprising items that were difficult to answer but easy to look up on the Internet. Half of the participants were invited to look up the solutions, which significantly increased their test scores. The PageFocus script detected test takers who abandoned the test page with very high sensitivity and specificity, and successfully reduced cheating by generating a popup message that asked participants not to cheat. In a second study, 510 online participants completed a knowledge test comprising items that could easily be looked up and a reasoning task involving matrices that were impossible to look up. In a first group, a performance-related monetary reward was promised to the top scorers; in a second group, participants took part in a lottery that provided performance-unrelated rewards; and in a third group, no incentive was offered. PageFocus revealed that participants cheated more when performance-related incentives were offered. As expected, however, this effect was limited to items that could easily be looked up. We recommend that PageFocus be routinely employed to detect and prevent cheating on online achievement tests.

  20. CaSePer: An efficient model for personalized web page change detection based on segmentation

    Directory of Open Access Journals (Sweden)

    K.S. Kuppusamy

    2014-01-01

    Full Text Available Users who visit a web page repeatedly at frequent intervals are more interested in knowing the recent changes that have occurred on the page than the entire contents of the web page. Because of the increased dynamism of web pages, it would be difficult for the user to identify the changes manually. This paper proposes an enhanced model for detecting changes in the pages, which is called CaSePer (Change detection based on Segmentation with Personalization. The change detection is micro-managed by introducing web page segmentation. The web page change detection process is made efficient by having it perform a dual-step process. The proposed method reduces the complexity of the change-detection by focusing only on the segments in which the changes have occurred. The user-specific personalized change detection is also incorporated in the proposed model. The model is validated with the help of a prototype implementation. The experiments conducted on the prototype implementation confirm a 77.8% improvement and a 97.45% accuracy rate.

  1. An efficient scheme for automatic web pages categorization using the support vector machine

    2016-07-01

    In the past few years, with an evolution of the Internet and related technologies, the number of the Internet users grows exponentially. These users demand access to relevant web pages from the Internet within fraction of seconds. To achieve this goal, there is a requirement of an efficient categorization of web page contents. Manual categorization of these billions of web pages to achieve high accuracy is a challenging task. Most of the existing techniques reported in the literature are semi-automatic. Using these techniques, higher level of accuracy cannot be achieved. To achieve these goals, this paper proposes an automatic web pages categorization into the domain category. The proposed scheme is based on the identification of specific and relevant features of the web pages. In the proposed scheme, first extraction and evaluation of features are done followed by filtering the feature set for categorization of domain web pages. A feature extraction tool based on the HTML document object model of the web page is developed in the proposed scheme. Feature extraction and weight assignment are based on the collection of domain-specific keyword list developed by considering various domain pages. Moreover, the keyword list is reduced on the basis of ids of keywords in keyword list. Also, stemming of keywords and tag text is done to achieve a higher accuracy. An extensive feature set is generated to develop a robust classification technique. The proposed scheme was evaluated using a machine learning method in combination with feature extraction and statistical analysis using support vector machine kernel as the classification tool. The results obtained confirm the effectiveness of the proposed scheme in terms of its accuracy in different categories of web pages.

Through a detailed analysis of choice of words, thematic structure, the usage of pronouns and intertextuality, the ideology hidden behind the text is revealed. Media may unconsciously manipulate the public’s recognition and understandings. If people want to have a comprehensive interpretation of a social phenomenon, they need to make a detailed critical analysis of the texts by taking the background information into consideration and to explore the underlying ideology.

    On The Idea and Practice of 'The Imperial Palace Integrity' Conservation Zheng Xinmiao ABSTRACT: This paper, from the sequences of time and space, conducts an overview of the exploration and practice in preserving and conserving The Imperial Palace as a whole over the past nine decades or so, making a relatively objective comment on them thereby. The strategy of 'The Imperial Palace integrity preservation and administration' was initiated by the Palace Museum from its beginning and then determined the scope under its administration. With the era of refrom and opening-up coming around there has been an increasing awareness of the ' integrity of The Imperial Palace' in spite of its ever being weakened for a time. 'The integrity of the Imperial Palace' as stated in the visual scope of the world heritage preservation and conservation specifically refers to its authenticity and integrity. The cultural value of the imperial palace as a whole is the focus in the field of Gugong studies. Well then, the idea of 'The Integrity of the Imperial Palace' is embodied in the methodology and mode of thinking to guide and advance the conservation of this world heritage site and the construction of The Palace Museum. In a word, with the times passing by, the conservation idea and practice have been changing but they are integrated with the mutual inspiration, supplement and a part of blend among them.

    Addison, J. A.

    2015-12-01

    The Past Global Changes (PAGES) project of IGBP and Future Earth supports research to understand the Earth's past environment to improve future climate predictions and inform strategies for sustainability. Within this framework, the PAGES 2k Network was established to provide a focus on the past 2000 years, a period that encompasses Medieval Climate Anomaly warming, Little Ice Age cooling, and recent anthropogenically-forced climate change. The results of these studies are used for testing earth system models, and for understanding decadal- to centennial-scale variability, which is needed for long-term planning. International coordination and cooperation among the nine regional Working Groups that make up the 2k Network has been critical to the success of PAGES 2k. The collaborative approach is moving toward scientific achievements across the regional groups, including: (i) the development of a community-driven open-access proxy climate database; (ii) integration of multi-resolution proxy records; (iii) development of multivariate climate reconstructions; and (iv) a leap forward in the spatial resolution of paleoclimate reconstructions. The last addition to the 2k Network, the Ocean2k Working Group has further innovated the collaborative approach by: (1) creating an open, receptive environment to discuss ideas exclusively in the virtual space; (2) employing an array of real-time collaborative software tools to enable communication, group document writing, and data analysis; (3) consolidating executive leadership teams to oversee project development and manage grassroots-style volunteer pools; and (4) embracing the value-added role that international and interdisciplinary science can play in advancing paleoclimate hypotheses critical to understanding future change. Ongoing efforts for the PAGES 2k Network are focused on developing new standards for data quality control and archiving. These tasks will provide the foundation for new and continuing "trans-regional" 2k

    Full Text Available This research aims to compare the perceived effectiveness of teacher -led and student-led content management approaches embraced in a course Facebook page designed to enhance traditional classroom learning. Eighty-five undergraduate marketing course students voluntarily completed a questionnaire composed of two parts; a depiction of a course Facebook page where both teacher and students can share instructional contents, and questions about perceived learning effectiveness. The findings indicate that students have more favorable evaluations of a student-led approach in sharing instructional contents on a course Facebook Page than a teacher-led approach. Additionally, it is shown that instructional contents posted by both teacher and students enhance the overall learning effectiveness of a course Facebook page incorporated into a traditional classroom teaching.

    Metal content of metalloproteins can be detected and even quantified by the PIXE-PAGE method. In this technique the proteins are separated by thin layer electrophoresis (by polyacrylamide gel electrophoresis (PAGE) in most cases) and the properly dried gel sections are analyzed by PIXE using 'band-shaped' proton milli-beam. This PIXE-PAGE method was adapted for our scanning proton microprobe. The microPIXE-PAGE version provides two-dimensional elemental mapping of the protein bands. In addition, the fast continuous scanning reduces the risk of the thermal deterioration of the sample and the X-ray contribution from dust-impurities can be filtered out in the data evaluation process.

    2016-01-01

    The rise of big data systems has created a need for benchmarks to measure and compare the capabilities of these systems. Big data benchmarks present unique scalability challenges. The supercomputing community has wrestled with these challenges for decades and developed methodologies for creating rigorous scalable benchmarks (e.g., HPC Challenge). The proposed PageRank pipeline benchmark employs supercomputing benchmarking methodologies to create a scalable benchmark that is reflective of many real-world big data processing systems. The PageRank pipeline benchmark builds on existing prior scalable benchmarks (Graph500, Sort, and PageRank) to create a holistic benchmark with multiple integrated kernels that can be run together or independently. Each kernel is well defined mathematically and can be implemented in any programming environment. The linear algebraic nature of PageRank makes it well suited to being implemented using the GraphBLAS standard. The computations are simple enough that performance predictio...

  2. Definition, Detection, and Recovery of Single-Page Failures, a Fourth Class of Database Failures

    CERN Document Server

    Graefe, Goetz

    2012-01-01

    The three traditional failure classes are system, media, and transaction failures. Sometimes, however, modern storage exhibits failures that differ from all of those. In order to capture and describe such cases, single-page failures are introduced as a fourth failure class. This class encompasses all failures to read a data page correctly and with plausible contents despite all correction attempts in lower system levels. Efficient recovery seems to require a new data structure called the page recovery index. Its transactional maintenance can be accomplished writing the same number of log records as today's efficient implementations of logging and recovery. Detection and recovery of a single-page failure can be sufficiently fast that the affected data access is merely delayed, without the need to abort the transaction.

    In this paper, we analyze the efficiency of Monte Carlo methods for incremental computation of PageRank, personalized PageRank, and similar random walk based methods (with focus on SALSA), on large-scale dynamically evolving social networks. We assume that the graph of friendships is stored in distributed shared memory, as is the case for large social networks such as Twitter. For global PageRank, we assume that the social network has $n$ nodes, and $m$ adversarially chosen edges arrive in a random order. We show that with a reset probability of $\\epsilon$, the total work needed to maintain an accurate estimate (using the Monte Carlo method) of the PageRank of every node at all times is $O(\\frac{n\\log m}{\\epsilon^{2}})$. This is significantly better than all known bounds for incremental PageRank. For instance, if we naively recompute the PageRanks as each edge arrives, the simple power iteration method needs $\\Omega(\\frac{m^2}{\\log(1/(1-\\epsilon))})$ total time and the Monte Carlo method needs $O(mn/\\epsilon)...

    Google's PageRank has created a new synergy to information retrieval for a better ranking of Web pages. It ranks documents depending on the topology of the graphs and the weights of the nodes. PageRank has significantly advanced the field of information retrieval and keeps Google ahead of competitors in the search engine market. It has been deployed in bibliometrics to evaluate research impact, yet few of these studies focus on the important impact of the damping factor (d) for ranking purposes. This paper studies how varied damping factors in the PageRank algorithm can provide additional insight into the ranking of authors in an author co-citation network. Furthermore, we propose weighted PageRank algorithms. We select 108 most highly cited authors in the information retrieval (IR) area from the 1970s to 2008 to form the author co-citation network. We calculate the ranks of these 108 authors based on PageRank with damping factor ranging from 0.05 to 0.95. In order to test the relationship between these diffe...

    A new hepatocellular carcinoma risk prediction model, PAGE-B, which includes age, gender and platelet count as constituent variables, has recently been proposed in Caucasian chronic hepatitis B patients. We validated PAGE-B model and compared its accuracy with that of conventional risk prediction models in Asian chronic hepatitis B patients. Chronic hepatitis B patients treated with entecavir or tenofovir were consecutively recruited. The performance of PAGE-B and three conventional risk prediction models (CU-HCC, GAG-HCC and REACH-B) were analysed. A total of 1092 chronic hepatitis B patients (668 men, 61.2%) were selected between August 2006 and January 2015. The mean age was 48 years. During the follow-up period (median, 43.6 months), 36 (3.3%) patients developed hepatocellular carcinoma. Older age (hazard ratio [HR]=1.077), male gender (HR=3.676) and lower platelet count (HR=0.984) were independent predictors of hepatocellular carcinoma development. The PAGE-B showed similar area under receiver operating characteristic curves (AUROCs) to GAG-HCC and CU-HCC at 3 years (0.777 vs 0.793 and 0.743, respectively; all P>.05) and 5 years (0.799 vs 0.803 and 0.744, respectively; all P>.05), whereas the AUROCs of PAGE-B were significantly higher than those of the REACH-B (0.602 at 3 years and 0.572 at 5 years, P<.05). Our study demonstrated that PAGE-B is applicable to Asian chronic hepatitis B patients receiving ETV or TDF therapy. The PAGE-B showed similar predictive performance to GAG-HCC and CU-HCC. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Introduction. This paper extends a series on summaries of Web objects, in this case, the alt attribute of image files. Method. Data were logged from 1894 pages from Yahoo!'s random page service and 4703 pages from the Google directory; an img tag was extracted randomly from each where present; its alt attribute, if any, was recorded; and the header for the corresponding image file was retrieved if possible. Analysis. Associations were measured between image type and use of null alt values, image type and image file size, image file size and alt text length, and alt text length and number of images on the page. Results. 16.6% and 17.3% of pages respectively showed no img elements. Of 1579 and 3888 img tags randomly selected from the remainder, 47.7% and 49.4% had alt texts, of which 26.3% and 27.5% were null. Of the 1316 and 3384 images for which headers could be retrieved, 71.2% and 74.2% were GIF, 28.1% and 20.5%, JPEG; and 0.8% and 0.8% PNG. GIF images were more commonly assigned null alt texts than JPEG images, and GIF files tended to be shorter than JPEG files. Weak positive correlations were observed between image file size and alt text length, except for JPEG files in the Yahoo! set. Alt texts for images from pages containing more images tended to be slightly shorter. Conclusion. Possible explanations for the results include GIF files' being more suited to decorative images and the likelihood that many images on image-rich pages are content-poor.

    Wheeler emphasized the study of Superspace - the space of 3-geometries on a spatial manifold of fixed topology. This is a configuration space for GR; knowledge of configuration spaces is useful as regards dynamics and QM.In this Article I consider furthmore generalized configuration spaces to all levels within the conventional `equipped sets' paradigm of mathematical structure used in fundamental Theoretical Physics. This covers A) the more familiar issue of topology change in the sense of topological manifolds (tied to cobordisms), including via pinched manifolds. B) The less familiar issue of not regarding as fixed the yet deeper levels of structure: topological spaces themselves (and their metric space subcase), collections of subsets and sets. Isham has previously presented quantization schemes for a number of these. I consider some classical preliminaries for this program, aside from the most obvious (classical dynamics for each). Rather, I provide I) to all levels Relational and Background Independence ...

    OBJECTIVE: To assess the patterns of paging medical interns during night calls. DESIGN: Descriptive study; diaries were used to log calls between 7 pm and 7 am for 1 week in February 1991. SETTING: Two teaching hospitals in Halifax. PARTICIPANTS: All 10 interns assigned to the 15 medical units and nurses from 3 representative medical units. MAIN OUTCOME MEASURES: Number and nature of calls. RESULTS: The overall response rate was 90%. A total of 309 calls were logged by the interns and 107 by the nurses. Each intern had 17 calls on average (range 6 to 33) per 12-hour period. Of the calls 27% occurred after midnight, 25% disrupted sleeping, and 19% interrupted direct patient contact. Overall, the most common reasons for paging interns were related to prescribing of medications (42% of the calls), direct patient assessment (25%) and reporting of laboratory results (18%). According to the nurses, there were no delays in the interns' responding to the pages, and 61% of the calls led to a new physician order. CONCLUSIONS: Paging frequently interrupts interns during work and rest on night calls. Assessment of paging patterns may be useful in identifying specific interventions to reduce the number of calls so that interns will have fewer interruptions during patient encounters and more rest. The collection of data from nurses in a routine nursing audit may be useful for evaluating the communication between interns and nurses and, indirectly, for assessing interns' workload. PMID:8039084

    Answering pages from nurses about patients in need of immediate attention is one of the most difficult challenges a resident faces during their first days as a physician. A Mock Page program has been developed and adopted into a national surgical resident preparatory curriculum to prepare senior medical students for this important skill. The purpose of this study is to assess standardized mock page cases as a valid construct to assess clinical decision making and interprofessional communication skills. Mock page cases (n = 16) were administered to 213 senior medical students from 12 medical schools participating in a national surgical resident preparatory curriculum in 2013 and 2014. Clinical decision making and interprofessional communication were measured by case-specific assessments evaluating these skills which have undergone rigorous standard-setting to determine pass/fail cut points. Students' performance improved in general for both communication and clinical decision making over the 4-week course. Cases have been identified that seem to be best suited for differentiating high- from low-performing students. Chest pain, pulmonary embolus, and mental status change cases posed the greatest difficulty for student learners. Simulated mock pages demonstrate an innovative technique for training students in both effective interprofessional communication and management of common postoperative conditions they will encounter as new surgical interns.

    Urinary proteomic profiling has potential to identify candidate biomarkers of renal injury in infants provided an adequate urine sample can be obtained. Although diapers are used to obtain urine for clinical evaluation, their use for proteomic analysis has not been investigated. We therefore performed feasibility studies on the use of diaper-extracted urine for 2-D PAGE. Pediatric waste urine (2-20 mL) was applied to gel-containing, non-gel and cotton-gauze diapers and then mechanically expressed. Urine volume and total protein were measured pre- and post-extraction. Proteins were separated via 2-D PAGE following application of urine (20-40 mL) to each matrix. 2-D PAGE was also performed on clinical specimens collected using each diaper type. Differences in the adsorption and retention of urine volume and protein were noted between matrices. Non-gel and cotton-gauze diapers provided the best protein/volume recovery and the lowest interference with the Bradford assay. 2-D PAGE was also successfully completed using urine samples from both cotton fiber matrices. Conversely, samples from low-gel diapers demonstrated poor protein separation and reproducibility. Diapers containing cotton-fiber matrices appear adequate for 2-D PAGE. Qualitative and quantitative analyses of resolved proteins using replicate, high-resolution gels will be required, however, before diaper-extracted urine can be applied in proteomic profiling.
