Automatic keyphrase extraction aims to pick out a set of terms as a representation of a document without manual assignment efforts. Supervised and unsupervised graph-based ranking methods have been studied for this task. However, previous methods usually computed importance scores of words under the assumption of single relation between words. In this work, we propose WordTopic-MultiRank as a new method for keyphrase extraction, based on the idea that words relate with each other via multiple relations. First we treat various latent topics in documents as heterogeneous relations between words and construct a multi-relational word network. Then, a novel ranking algorithm, named Biased-MultiRank, is applied to score the importance of words and topics simultaneously, as words and topics are considered to have mutual influence on each other. Experimental results on two different data sets show the outstanding performance and robustness of our proposed approach in automatic keyphrase extraction task. © IJCNLP *** right reserved.

Reconstruction of gene regulatory networks or 'reverse-engineering' is a process of identifying gene interaction networks from experimental microarray gene expression profile through computation techniques. In this paper, we tried to reconstruct cancer-specific gene regulatory network using information theoretic approach - mutual information. The considered microarray data consists of large number of genes with 20 samples - 12 samples from colon cancer patient and 8 from normal cell. The data has been preprocessed and normalized. A t-test statistics has been applied to filter differentially expressed genes. The interaction between filtered genes has been computed using mutual information and ten different networks has been constructed with varying number of interactions ranging from 30 to 500. We performed the topological analysis of the reconstructed network, revealing a large number of interactions in colon cancer. Finally, validation of the inferred results has been done with available biological databases and literature.

The increasing use of wireless Internet and smartphone has accelerated the need for widespread computing. Smartphones stimulate growth of Global Position systems (GPS) and mobile cloud computing. Mobile cloud computing is the cloud infrastructure where the computation and storage are moved away from mobile devices. However, smartphone mobile computing poses challenges because of the limited battery capacity, constraints of wireless networks and the limitations of device. Therefore, it is necessary to offload the computation-intensive part by careful partitioning of application functions across a cloud. Mobile applications can be executed in the mobile device or offloaded to the cloud clone for execution, in this paper;we propose a new elastic application model that enables transparent use of cloud resources to augment the capability of resource constrained mobile devices. The significant features of this model include the partition of a single application into multiple components. Its execution location is transparent it can be run on a mobile device or migrated to the cloud. Thus, an elastic application can augment the capabilities of a mobile device including computation power, storage, and network bandwidth, with the light of dynamic execution configuration according to device's status including CPU load, memory, battery level. We demonstrate promising results of the proposed application model using data collected from one of our example elastic applications. © 2013 IEEE.

Grid Manufacturing (GM) is a new production paradigm, based upon the use of standardized and modular Reconfigurable Manufacturing systems (RMS). In GM all systems have a virtual counterpart that actsautonomously, this includes both complete manufacturing systems and the products. The control system required for this approach is based upon a distributed and hybrid architecture, using agent technology. An important aspect in the paradigm is the product manufacturing description. This paper introduces the concept of an architecture where the control of the manufacturing is abstracted from the product manufacturing blueprint. A product is delineated step by step by specific services in the grid. The proposed system increases flexibility twofold, first by enabling abstraction of product's parts and second by dynamically using manufacturing means. © 2013 IEEE.

Manufacturing scheduling is one of the important and complex combinatorial optimization problems in manufacturing system, where it can have a major impact on the productivity of a production process. Moreover, most of scheduling problems fall into the class of NP-hard combinatorial problems. In this paper, we concern with the design of multiobjective evolutionary algorithms (MOEAs) to solve a variety of manufacturing scheduling problems. In particularly, the fitness assignment mechanism and evolutionary representations as well as the hybrid evolutionary operations are introduced. Also, several applications of EAs to the different types of manufacturing scheduling problems are illustrated. Through a variety of numerical experiments, the effectiveness of these Hybrid EAs (HEAs) in the widely applications of manufacturing scheduling problems are demonstrated. This paper also summarizes a classification of scheduling problems and the design way of EAs for the different types of manufacturing scheduling problems in which we apply EAs to job-shop scheduling problem (JSP;operation sequencing), flexible JSP model (FJSP;operation sequencing with resources assignment), assembly line balancing models (ALB;shipments grouping and assignment), integrated process planning and scheduling (IPPS;operation sequencing with multiple resources assignment). It is useful to guide how to investigate an effective EA for the practical manufacturing scheduling problems.

Cloud computing is a new paradigm with a promising potential. However, issues of security, privacy, and trust raise concerns and discourage its adoption. In previous work we presented a framework for the selection of appropriate cloud provider based on security and privacy requirements criteria. However, the adoption of cloud includes release of control over valuable assets, which constitutes trust in the cloud provider of paramount importance. In this paper we extend the framework by incorporating trust and control concepts in its language and adding a new activity to properly identify and reason about trust assumptions during the selection of appropriate cloud provider. Also, the CASE tool was extended to support the new activity. A case study is used to illustrate the usefulness of our approach. © 2013 Springer-Verlag.

Nonmonotonic description logic programs (dl-programs) are a well-known formalism for combining rules and ontologies, where rules interact with an underlying ontology via dl-atoms that allow queries to the ontology under a possible update of its assertional part. It is known that dl-atoms may be nonmonotonic and dl-programs without nonmonotonic dl-atoms have many desirable properties. In this paper, we show that it is possible to remove nonmonotonic dl-atoms from a dl-program while preserving its strong/weak answer set semantics. Though the translation is faithful, it relies on the knowledge about monotonicity of dl-atoms. We then thoroughly investigate the complexity of deciding whether a dl-atom is monotonic under the description logics DL-Litescript R, scriptEscriptL++, scriptSscriptHscriptIscriptF and scriptSscriptHscriptOscriptIscriptN, which is of independent interest for computing strong answer sets. We show that the problem is intractable in general, but tractable for dl-atoms with bounded queries in DL-Litescript R. © 2013 Springer-Verlag.

Quantum Nondemolition Detection of a Propagating Microwave Photon

The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement. Realizing such a detector is complicated by the fact that photon-photon interactions are typically very weak. At microwave frequencies, very strong effective photon-photon interactions in a waveguide have recently been demonstrated. Here we show how this type of interaction can be used to realize a quantum nondemolition measurement of a single propagating microwave photon. The scheme we propose uses a chain of solid-state three-level systems (transmons) cascaded through circulators which suppress photon backscattering. Our theoretical analysis shows that microwave-photon detection with fidelity around 90% can be realized with existing technologies.

A plan of study enumerates the courses recommended by an academic program along with a time frame to complete the requirements of a degree or credential. A general plan of study can be recommended by an academic department or college to all of its students or, as an alternative, personalized plans of study can be created for each student by his/her academic advisor. This paper presents a case study of assessing the recommended as well as personalized plans of study in terms of their affect on students' performance using data mining techniques. The study was conducted at the information systems Department, Faculty of computing and information technology, King Abdulaziz University. We computed the degree to which each student followed the recommended plan of study and correlated this to the students GPA to assess the impact of the plan of study to the academic performance. Our results showed a statistically significant, moderate positive correlation indicating that following the recommended plan of study has a positive impact on the academic performance. To assess the personalized plans of study proposed by the academic advisor, we built and compared three models to predict the GPA resulting from these plans. Given a proposed plan of study, our model was able to predict the correct GPA with a 0.44 root mean squared error.
