The management of university web sites is becoming more critical than before due to the rapid growth of the population dep.ndent on the world wide web as the most important (if not the only) information source. A university can spread its research outcomes and education achievements through its web site, and consequently gain visibility and influence from the web population. Webometrics Ranking of World Universities (WR) proposed by Centre for Scientific Information and Documentation (CINDOC-CSIC), which ranks the university web sites, has obtained much attention recently. The rankings of WR are well recognized as an important index for universities willing to promote themselves by the internet technology. In this paper, we proposed WRES as an early warning system for Webometrics Rankings. WRES gathers the WR indices from the WWW automatically in flexible periods, and provides useful information in real time for the managers of university web sites. If the WR ranking of an institution is below the expected position according to their academic performance, university authorities should reconsider their web policy, by promoting substantial increases of the volume and quality of their electronic publications. Besides, the web site manages may adopt effective approaches to promote their WR rankings according to the hints given by WRES. © (2012) Trans Tech Publications, Switzerland.

This paper presents a measurement study of the topology and its effect on usage of ***, a large-scale community network. It focuses on the main issues faced by community network and lessons to consider for its future growth in order to preserve its scalability, stability and openness. The results show the network topology as an atypical high density Scale-Free network with critical points of failure and poor gateway selection or placement. In addition we have found paths with a large number of hops i.e. large diameter of the graph, and specifically long paths between leaf nodes and web proxies. The usage analysis using a widespread web proxy service confirms that these topological properties have an impact on the user experience. © 2012 IEEE.

A new approach for feature selection is presented in this paper. The proposed approach uses the Harmony Search with a novel fitness function to eliminate noisy and irrelevant features. Harmony vectors contain real weights which refer to feature space. The best and significant features are selected according to a threshold. Fitness function of Harmony Search is based on the Area Under the receiver operating characteristics Curve (AUC). All of the selected features are employed to improve the classification of the k Nearest Neighbor (k-NN) classifier. Experimental results claim that the proposed method is able to improve the classification performance of k-NN algorithm in comparison with the other important methods in realm of feature selection such as BAHSIC, FSS, BSS and MFS.

During a real time control process, a set of controllers that use different control policies have been used to control the temperature of a simulated room during 200 minutes under the same conditions. All the realized simulations have been repeated five times with two different sets of set points. A quantitative comparison between the performance of the conventional controllers and the new Adaptive and Self-Organizing Fuzzy Controller proposed in this work will be performed. This latter can adapt and self-organize their internal parameters in real time using just a few qualitative information about the plant (the monotonicity sign and the delay time) and without allocate a rule base. Using all results of the performed simulations as a set of sampling for the statistical tool ANOVA (Analysis Of Variance), we have been able to emphasize the extrapolability of the obtained results (the committed error and the power consumption) and illustrate the great contribution that brings the new Adaptive and Self-Organizing Fuzzy Control policy proposed in this paper.

Many cultural heritage institutions are confronted with a big challenge when it comes to adapting the process of registration, annotation and digitization of their collections to meet the new technological demands for providing their collections online with Web and mobile technologies. With limited funding and limited professional resources, annotation is often lagging behind significantly in terms of quantity and level of detail. Quantity as well as quality of the annotations is the key to finding relevant objects by various groups of users in online collections. As many experiments with cultural heritage data online show, human computation can be useful for collecting large quantities of data. Various of these experimented with a crowd of lay people to help with the annotation of cultural heritage artefacts. However, a common concern relates to the resulting quality. The current trend appears to focus on supporting 'the crowd' to achieve the desired level of quality. In this paper, we discuss the results of the first phase of an evolutionary system design performed in collaboration with the Rijksmuseum Amsterdam, as part of the SEALINCMedia project. By providing personalized support to the individuals and groups in the 'crowd' when annotating museum collection objects, we also support the integration of the annotation result in the RMA content management system. The contribution of this paper is twofold: (1) requirements specification for a crowdsourcing annotation process and (2) design of the personalization functionality in a crowdsourcing annotation system. © Springer-Verlag Berlin Heidelberg 2011.

Boolean satisfiability (SAT) solvers are used heavily in electronic engineering verification tools for checking satisfiability of Boolean formulas. Most state-of-the-art SAT solvers are based on the DPLL algorithm and require the input formula to be in conjunctive normal form (CNF). We represent the vhpform of a given NNF formula in the form of two graphs called vpgraph and hpgraph. The input formula is translated into a 2-dimensional format called vertical-horizontal path form (vhpform). In this form disjuncts (operands of) are arranged orizontally and conjuncts (operands ofˆ) are arranged *** formula is satisfiable if and only if there exists a vertical path through this arrangement that does not contain two opposite literals (l and ¬l). The input formula is not required to be in CNF. This algorithm is very important both for the design of integrated circuit and the development of electronic engineering. © 2012 Springer-Verlag Berlin Heidelberg.

Wireless cellular networks have gained a great success in the past few years. However, with the trend of network structure to be more heterogeneous and integrated new challenges arise, among which efficiently allocating resource for supporting multiple traffic (voice, video, data, and etc) is the crucial one. Meanwhile, achieving seamless mobility which involving supports for both roaming and handoff between networks is another important challenge. Under this environment, channel allocation control (CAC), especially the handoffs management is still the key issue to the QoS and resource utilization (RU) of wireless cellular networks. In this paper, we address RU as well as grade of service (GoS) analysis concerned with the adaptive guard channels control scheme for differentiated traffic types in wireless cellular networks.

This paper considers the characteristics of high-speed train in precise timing information, such as arrival time, dep.nding duration on station, traveling time and location of the train, to design a video proxy agent for VoD service in train. Based on the information of current active video streams, a burst pre-fetching scheme in video proxy agent is developed when the high-speed train dep.nds on station. The video data required by the passengers in near future are burst downloaded to the video proxy to release the bandwidth constrain during the train traveling. The most of playback video data can be provided by the video proxy agent during the train traveling. The burst pre-fetching scheme increases the system performance and video playback quality. The simulation result reveals that the proposed scheme has better results in term of system capacity and the amount of missed deadline data compared with other schemes.

Web 2.0 has facilitated interactive information sharing on the WWW, allowing users the opportunity to articulate their opinions on different topics. In this framework, certain practices implement information monitoring systems so as digests, reports on keywords and thematic queries regarding opinions on government decisions to be created. Analysis of rubrics associations, primary semantic and statistical interpretation of the texts is usually carried out. It is, on the other hand, rather difficult to get punctual predicts and estimate sufficiently forum users' opinion strength. In this work we present a methodology which automatically mines and estimates the strength of users' opinions on text forums regarding government decisions. According to our methodology, quantitative features are automatically mined from forum posts and then passed to a Support Vector Machine based classifier where the users' opinion strength is estimated. The proposed methodology has been validated in real data and initial experimental results are presented. © 2012 IFIP International Federation for Information Processing.
