    Full text link
    Today’s business applications are increasingly process driven, meaning that the main application logic is executed by a dedicate process engine. In addition, component-oriented software development has been attracting attention for building complex distributed applications. In this paper, we present the experiences gained from building a process-driven biometric identification application that makes use of grid infrastructures via the Grid Component Model (GCM). GCM, besides guaranteeing access to grid resources, supports autonomic management of notable parallel composite components. This feature is exploited within our biometric identification application to ensure real-time identification of fingerprints. Therefore, we briefly introduce the GCM framework and the process engine used, and we describe the implementation of the application by means of autonomic GCM components. Finally, we summarise the results, experiences and lessons learned focusing on the integration of autonomic GCM components and the process-driven approach

    Welcome to the COMPSAC 2016 Symposium on Mobile, Wearable, and Ubiquitous Computing (MOWU). Riding on the rapidly growing trend in making the world highly connected via various communication infrastructures and ubiquitous portable devices, especially high bandwidth wireless communication, regardless of user location and device mobility, it is important to develop applications taking full advantage of these technological advancements. MOWU is focused on recent advances in wireless communications and the proliferation of powerful mobile devices, noticeably smart phones and Internet of Things (IoT) nodes that have enabled a wide range of mobile services, everywhere and anytime. The symposium echoes the main theme of COMPSAC 2016 on “Connected World: New Challenges for Data, Systems & Applications”, addressing challenges in emerging application domains such as connected health, wearable computing, IoT, cyber-physical systems, and smart planet. MOWU’s primary objective is to attract presentations by both researchers and practitioners of their recent results, findings, and achievements in all components of the pervasive ubiquitous environments including the advancement of middleware technologies in various mobile-related sectors, ranging from effective synergic management of wireless communications to dynamic adaptiveness of system software, and from horizontal support of crowdsourcing in different application domains to dynamic offloading on cloud resources. By fostering innovation, the main goal of MOWU is to advance the understanding of and addressing the technical challenges in mobile communications regarding current and future mobile services, applications, and devices for wearable and ubiquitous computing. The Second MOWU Symposium received a total of 16 full submissions. We are honored to have invited renowned researchers to serve on the program committee, providing comprehensive reviews to the submissions. In particular, each individual submission underwent a rigorous double-blind review process assisted by program committee members. Each paper received at least three reviews and some papers received five reviews. Moreover, to guarantee high quality and consistency of the review process, metareviews were discussed by the conference and symposia program chairs during a dedicated PC meeting, hosted this February by Hiroyuki Sato of University of Tokyo. Finally, we accepted 18.8% of the submissions as regular papers and 6.3% as short papers for inclusion into this year’s COMPSAC proceedings, published by IEEE Computer Society. The selected papers are clustered around localization and mobile data management, thus demonstrating the current interest of the researchers’ community in these “hot” fields. We strongly believe that the accepted full papers are of extremely high quality and will provide a valuable technical contribution to the community. Given the overall (full + short) acceptance rate of only 25%, the review process was highly competitive, and it is indeed unfortunate that many good quality papers could not be accepted to be included in the MOWU technical program

    The author states his opinion that the most valuable contribution of the July 2007 issue is Gene Amdahl's new paper, which he thinks will probably become as popular as the Amdahl paper reprinted in the same issue since it provides much needed clarifications, and most notably includes the original 'law' formula as presented by Amdahl four decades ago

    A mapping language for IoT device descriptions

    Full text link
    Component models for IoT devices regain popularity. As more and more devices must be semantically connected within IoT platforms, digital abstractions for these devices are needed. For this purpose, textual device descriptions which encapsulate device-specific characteristics are a suitable candidate. Such component descriptions formally describe a device’s information model as well as the offered functionality in a standardized way. However, smart IoT platforms mainly solve user goals by composing various IoT devices in a suitable manner. Current IoT descriptions, such as Eclipse Vorto do not address this need at all. In this paper, we introduce a formal mapping language that allows to capture functional interaction semantics already during device integration time. Our evaluation shows that only few mapping elements are needed to define functional mappings between operations as well as to capture the underlying communication pattern

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    No full text
    This report presents the design and implementation of a middleware for building large-scale, dynamic, and self-organizing distributed applications for the Internet. First, we identify the challenges that are faced when building this type of applications and the constraints imposed on the middleware that is to support them. We derive a set of essential services that are to be provided by our middleware in order to facilitate the development of distributed applications. These services include scalable communication, failure detection, name-based overlay routing, group communication and a distributed hash table abstraction. We present the event-based component-oriented architecture of the system, discussing the design choices that we made in order to meet the aforementioned challenges and constraints while providing the essential services for distributed applications. We describe in detail the event scheduling mechanism, the communication and failure detection, as well as the interface to applications and other miscellaneous services
