Bibliometrics in Online Book Discussions: Lessons for Complex Search Tasks

Online book discussion forums provide rich information on how readers think about and describe books, how books are related to other books and how people search for and recommend books. Within the Social Book Search (SBS) Lab at CLEF we analyse book search requests on the LibraryThing forums and find several types of complex search tasks where bibliometrics naturally combines with information retrieval. This paper explores how book search information needs in online book discussions are related to bibliometric analysis and how the structure of book citations in reviews and discussions can support complex book search tasks where users want to go beyond topical relevance ranking and see how books are related to each other and particularly to the books and authors they know.
Bit Error Rate Minimizing Channel Shortening Equalizers for Cyclic Prefixed Systems

Cyclic prefixed communications, such as multicarrier communications, first became widely used in the context of digital subscriber lines (DSL). In DSL, bit loading is allowed at the transmitter, and the performance metric is the bit rate that can be provided without exceeding a given bit error rate (BER). Wireless cyclic prefixed systems are now becoming increasingly popular, and in such systems the appropriate performance metric is the BER for a given bit loading at the transmitter. Cyclic prefixed systems perform well in the presence of multipath, provided that the channel delay spread is shorter than the guard interval between transmitted blocks. If this condition is not met, a channel shortening equalizer can be used to shorten the channel to the desired length. Previous work on channel shortening has largely been in the context of DSL, thus it has focused on maximizing the bit rate. In this paper, we propose a channel shortener that attempts to directly minimize the BER for a multiple-input multiple-output channel model. We simulate the performance of the resulting channel shortener and compare it to existing designs and the matched filter bound
Magnetic Fields of Accreting X-Ray Pulsars with the Rossi X-Ray Timing Explorer

Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars in the Rossi X-Ray Timing Explorer (RXTE) database that exhibit cyclotron resonance scattering features (CRSFs, or cyclotron lines). These sources in our sample are Her X-1, 4U 0115+63, Cen X-3, 4U 1626-67, XTE J1946-274, Vela X-1, 4U 1907+09, 4U 1538-52, GX 301-2, and 4U 0352+309 (X Per). We searched for correlations among the spectral parameters, concentrating on how the cyclotron line energy relates to the continuum and therefore how the neutron star B-field influences the X-ray emission. As expected, we found a correlation between the CRSF energy and the spectral cutoff energy. However, with our consistent set of fits we found that the relationship is more complex than what has been reported previously. Also, we found not only that the width of the cyclotron line correlates with the energy (as suggested by theory), but also that the width scaled by the energy correlates with the depth of the feature. We discuss the implications of these results, including the possibility that accretion directly affects the relative alignment of the neutron star spin and dipole axes. Finally, we comment on the current state of fitting phenomenological models to spectra in the RXTE/BeppoSAX era and the need for better theoretical models of the X-ray continua of accreting pulsars.
A NOVEL METHOD FOR PETRI NET MODELING

Message Sequence Chart (MSC) is a graphical trace language for describing the communication behaviour of distributed systems. In order to build a Petri Net model of a complex system, this paper introduces a strategy to build a Petri Net model by using MSC. The algorithm of translating the MSC model to Petri Net model is also given in this paper. We can get the Petri Net model and improve it by translating the model of MSC. By analyzing the Petri Net model, it is proved to be safe and reliable.

Cloud computing can simply be described as computin g based on the internet. In the past, people depend e on physical computer storage or servers to run their programs. However, with the introduction of cloud computing, people as well as business enterprises can now access their programs through the internet. Due this ease, software compa nies and other agencies are shifting more towards cloud computing environment. To achieve better operational efficiency in many organizations and small or medium agencies is using Cloud environment for managing their data. It is a combination of a number of computing strategies and concepts such as Service Oriented Ar chitecture (SOA), virtualization and other which rely on the Internet. Cloud Computing provides an easy way for accessing, manag in and computation of user data, but it also has s ome severe security risks. Very common risks now days are data theft at tacks. Data theft considered one of the top threats to cloud computing by the Cloud Security Alliance is. To deal with such cases and malicious intruders there are some techniques w hich are used to secure user data. A new technology called “Fog computing” is gaining attention of the cloud users nowadays. Fog computing improves the Quality of service and a lso reduces latency. According to Cisco, due to its wide geographical distribution the Fog computing is well suited for real time analytics and big data.Fog co mputing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users.

Optimal virtual traffic light placement

Traffic jams remain a challenging open problem inside and in vicinity of big cities around the world. This leads to a loss of "precious" working time during rush hours, and to the waste of huge amount of fuel which is also undesirable in terms of carbon emission. In this context, traffic light constitutes the bottleneck of the traffic flow system. In addition, disregard of traffic light is the major cause of road accidents. In this paper, we propose a novel traffic light system in which the traffic light scheduling and location are broadcasted, using wireless technology, to each (automated) vehicle. Using a virtual or additional physical traffic light, in conjunction with the original physical traffic light, we develop a scheme which increases the capacity of the intersection. The increased performance of the proposed scheme is illustrated analytically and with simulations. We show in both cases an increase of 5 to 20% in the fraction of undelayed vehicles, depending on the scenario, and a decrease of up to 50% in the average waiting time. Moreover, our scheme makes the traffic light system much more safe by eliminating the immediate danger in crossing the "red" traffic light.
Modal Analysis of Substrate Integrated Waveguides With Rectangular Via-Holes Using Cavity and Multilayer Green's Functions

The substrate integrated waveguide (SIW) comprising rectangular via-holes is herein treated by a rigorous full-wave modal analysis using the moment method entailing Green's functions for rectangular cavities and planar multilayer structures in the spectral domain. Modal dispersion graphs generated by this solution approach are compared with those obtained by an independent commercial full-wave solver. The ability of the modal solution in treating SIW junctions and discontinuities is demonstrated by the treatment of an interconnection between a conventional waveguide and a SIW using the mode-matching technique. Inhomogeneities within SIWs can also be accommodated by the technique, as showcased by a specific example of the so-called hard sidewalled SIW. Three avenues of losses, namely, dielectric, side-leakage, and conductor losses, are also investigated, thereby elucidating a tradeoff between the latter two.
Analysis of the dust evolution in the circumstellar disks of T Tauri stars

Aims. We present a compositional analysis of 8-13μm spectra of 32 young stellar objects (YSOs). Our sample consists of 5 intermediate-mass stars and 27 low-mass stars. Although some previous studies give reasons for the similarity between the dust in circumstellar disks of TTauri stars and Herbig Ae/Be stars, a quantitative comparison has been lacking so far. Therefore, we include a discussion of the results of the 10μm spectroscopic survey of van Boekel et al. (2005, A&A, 437, 189), who focus on Herbig Ae/Be stars, the higher mass counterparts of TTauri stars, and draw comparisons to this and other studies. Methods. While the spectra of our 32 objects and first scientific results have already been published elsewhere we perform a more detailed analysis of the ∼10μm silicate feature. In our analysis we assume that this emission feature can be represented by a linear superposition of the wavelength-dependent opacity K abs (λ) describing the optical properties of silicate grains with different chemical composition, structure, and grain size. Determining an adequate fitting equation is another goal of this study. Using a restricted number of fitting parameters, we investigate which silicate species are necessary for the compositional fitting. Particles, with radii of 0.1 μm- and 1. 5μm and consisting of amorphous olivine and pyroxene, forsterite, enstatite, and quartz are considered. Only compact, homogeneous dust grains are used in the presented fitting procedures. In this context we show that acceptable fitting results can also be achieved if emission properties of porous silicate grains are considered instead. Results. Our analysis shows - in terms of the properties of the circumstellar dust-like crystallinity - T Tauri systems are a continuation of HAeBe systems at their lower mass end. However, a weak correlation between grain growth and stellar luminosity could be found, in contrast to HAeBe systems.
Shareholder Value: A Business Experience

Shareholder Value presents a powerful and useful toolkit of market-based perspectives, analytic approaches, valuation techniques, and specific financial metrics for use in everyday business life. The author helps a broad spectrum of professionals understand the salient points and real world implications of a 'value management' movement which has taken hold in many corporations in the United States and around the world. This movement is being supported by some of the major institutional investors who influence financial markets. The main goal of 'Shareholder Value' is to help working professionals grasp the concept of value 'creators' and 'destroyers', along with the implications. He also provides tools to measure the success (or failure) of major strategic and operational initiatives and enables corporate managers to understand how shareholder value is created, and then directs behaviour toward 'value-based' planning and action. Although mainly aimed at the professional market, 'Shareholder Value' will also be of use to students of business and finance as it is intended to provide a comprehensive foundation for important elements of business strategy and acquisition valuation, corporate financial analysis, capital investments, corporate financing and economic value based metrics. AUTHOR'S REVIEW: When developing this book, I strived to achieve the following: Provide the finance professional and student of finance with a comprehensive template of shareholder value concepts and techniques - geared toward use in a corporate setting Give the non-financial professional an understanding of the underpinnings and behavioural aspects of economic value management Outline and provide details of an effective process for implementing a value-based financial performance system within a corporation . And, combine learning with enjoyable reading by presenting technical material through a story. The "story" and "characters" are unique features of Shareholder Value - A Business Experience. The reader can get an appreciation of the environment surrounding value-based management, along with challenges that arise when transitioning from traditional "accounting" performance (where earnings and earnings per share reign supreme) to "economic" performance (where cash flow and return on investment are emphasized). Characters occupying operating and staff roles have been created to represent people that those working inside companies (large, medium and small) may encounter and, also, to invoke some humour. Insights into how to function in different corporate roles can be gained by following the characters through the story. Presents a combination of analysis and case study in which a strong technical treatment is blended with a fictional case study to offer clarity and explanation A practical and effective implementation process for a comprehensive financial performance system Offers a perspective of the role of different corporate and business unit functions in the implementation of value-based financial performance within a company
A Two-Component Model for the Light Curves of Hypernovae

The light curves of hypernovae, i.e., very energetic supernovae with E51 ≡ E/1051 ergs ≳5-10, are characterized by a phase of linear decline at epochs of a few months. Classical, one-dimensional explosion models fail to simultaneously reproduce the light curve near peak and at the linear decline phase. The evolution of these light curves may, however, be explained by a simple model consisting of two concentric components. The outer component is responsible for the early part of the light curve and for the broad absorption features observed in the early spectra of hypernovae, similar to the one-dimensional models. In addition, a very dense inner component is added, which reproduces the linear decline phase in the observed magnitude versus time relation for SN 1998bw, SN 1997ef, and SN 2002ap. This simple approach does contain one of the main features of jet-driven, asymmetric explosion models, namely, the presence of a dense core. Although the total masses and energies derived with the two-component model are similar to those obtained in previous studies that also adopted spherical symmetry, this study suggests that the ejecta are aspherical, and thus, the real energies and masses may deviate from those derived assuming spherical symmetry. The supernovae that were modeled are divided into two groups according to the prominence of the inner component: the inner component of SN 1997ef is denser and more 56Ni-rich, relative to the outer component, than the corresponding inner components of SN 1998bw and SN 2002ap. These latter objects have a similar inner-to-outer component ratio, although they have very different global values of mass and energy.
Semi-dynamic Scheduling of Parallel Tasks for Heterogeneous Clusters

Modular parallel applications can be structured by parallel tasks that implement the modules. The dependence structure of such parallel applications gives rise to a scheduling problem, which is determined either statically at compile-time, e.g. by using a suitable compiler tool, or dynamically at runtime. In this article, we present a semi-dynamic execution scheme for applications structured by parallel tasks. This execution scheme combines a statically computed schedule with a dynamic load balancing that can adapt the schedule at runtime of the application. In this way, it is possible to reduce load imbalances between processor groups that may exist in the static schedule resulting from platform heterogeneity or from an imprecise cost prediction. Experimental results for several scientific applications show that the semi-dynamic execution scheme leads to lower execution times compared to a static execution on a tightly coupled heterogeneous platform.
Auditory and Other Non-verbal Expressions of Affect for Robots

This work focuses on the use of non-verbal methods of communicating affect in non-anthropomorphic appearance-constrained robots. The concepts discussed can be applied to other types of robotic systems. The paper gives a survey of relevant literature from the psychology community. Non-verbal methods of affective expression cannot be the sole means of communicating affect in robotic systems; however it can be appropriate as part of a multi-modal affective system. Another important factor is the distance between the robot and human with which it is interacting. From the psychology literature, there are four main zones of social interaction: intimate (contact – 0.46 m), personal (0.46 – 1.22 m), social (1.22 – 3.66), and public (3.66 and beyond). Sounds, tones, and/or music are appropriate to use in the intimate and personal zones; however it is not likely to be appropriate in the social and public zones due to environmental background noise. Communications are often challenging in search and rescue applications. Injuries that can impair language processing and limited visibility due to environmental conditions necessitate the use of non-verbal methods of communicating affect to survivors located during search and rescue operations.
Insulin-like growth factor binding protein 5 and apoptosis in mammary epithelial cells

Insulin-like growth factors (IGFs) are important survival signals that can protect a range of cell types from apoptosis. Although IGF bioavailability is modulated by high affinity interactions with IGF-binding proteins (IGFBPs), there is currently no experimental evidence that IGFBPs regulate the survival function of IGFs in the mammary gland. We have examined IGFBP expression during mammary gland development and studied the effects of IGFBPs on IGF-mediated survival and signalling in mammary epithelial cells in culture. IGFBP-5 protein was greatly increased during days 1-3 of mammary gland involution, when levels of apoptosis are dramatically elevated to remodel the gland after lactation. Primary cultures of mammary epithelial cells (MECs) expressed IGFBP-5 from their basal surface suggesting that IGFBP-5 is suitably located to inhibit IGF signalling. Addition of exogenous IGFBP-5 and IGFBP-3 to MECs suppressed IGF-I-mediated survival, resulting in threefold greater apoptosis in cells incubated with IGF-I and IGFBP-5 compared with IGF-I alone. Examination of signalling pathways involved in apoptosis revealed that phosphorylation of PKB and the forkhead transcription factor, FKHRL1, was induced by IGFs, but that phosphorylation was blocked by IGFBP-5 and IGFBP-3. This study provides evidence that IGFBP-5 plays an important role in the regulation of apoptosis in the mammary gland.
Synchronization of networked multi-agents system with sampling communications

In this paper, synchronization of networked multi-agent system with sampling communications is investigated. We are particularly interested in the effect of different topologies on the maximum allowable sampling period for communications between agents so that synchronization is guaranteed, aiming to provide some guidelines in practical designs. The synchronization problem is firstly managed by the linear matrix inequality (LMI) method, and the maximum allowable sampling period is then obtained as a solution of an optimization problem. The feasibility of this approach is demonstrated with simulations, and the impacts of the topological structure on the maximum allowable sampling period on agent communications are reported.
Automatic Annotation of Genitives in Hindi Treebank

Noun with genitive marker in Indo-Aryan language can variously be a child of a noun, a verb or a complex predicate, thus making it an important parsing issue. In this paper, we examine genitive data of Hindi and aim to automatically determine the attachment and relational label of the same in a dependency framework. We implement two approaches: a rule based approach and a statistical approach. The rule based approach produces promising results but fails to handle certain constructions because of its greedy selection. The statistical approach overcomes this by using a single candidate approach that considers all the possible candidates for the head and chooses the most probable candidate among them. Both approaches are applied on controlled and open environment data. A Controlled environment refers to the situation when the relational labels are attested to the input data except for the genitive data; while open environment refers to cases in which the input is only POS tagged and chunked. The rule based and statistical systems produce a high accuracy of 95% and 97% respectively for attachment and perform considerably well for labeling in controlled environment but poorly in open environment.
High performance global placement and legalization accounting for fence regions

The placement problem has become challenging due to a variety of complicated constraints imposed by modern process technologies. Some of the most challenging constraints were highlighted during the ISPD 2015 placement contest and include fence region and target density constraints; these constraints are in addition to those issues that affect detailed routability such as pin shorts, pin access problems and cell spacing issues. These constraints not only make cell placement more difficult, but can impact the placement objectives such as wire length, routability and so forth. In this paper, we present a comprehensive technique to address fence region constraints in global placement and legalization while still considering detailed-routing issues. We combine concepts from image processing such as region coloring with parallel programming to efficiently deal with fence regions. We also introduce a heuristic method to adjust target densities while avoiding adverse effects on the quality of global routability. Numerical results using both the released and hidden benchmarks from the ISPD 2015 placement contest demonstrate the efficacy of our proposed techniques.
