Model-Based Techiniques for the Design of Modern Software Systems
Full text linkTHE Thesis reports on the work done for the definition of several techniques
to support the design of modern systems. SCA-PatternBox is a
framework for modeling service-oriented applications with design patterns
that also permits the validation and verification of their behavior. Security
Enhanced Docker study improves the use of SELinux in Docker. Two techniques
are presented: Docker Policy Module (DPM) improves the use of the
SELinux Type Enforcement (TE) model and Category minimization problem
improves the use of the SELinux Multi Category Security (MCS) model. J-CO
query language devised to query heterogeneous collections of JSON objects
stored in a NoSQL document DBMS such as MongoDB
An Eclipse framework to ease notification among MyUniBG apps
No full textThe widespread diffusion of Android OS has led to a rapid explosion of the Google Play store (previously Android Market). As of 2011, the Play store includes more applications than the Apple App Store. It is natural to compare this growth to what happened years ago in the area of the World Wide Web, although in the second case, the need was to allow users to interact and collaborate in a more easy way (e.g., social network), while now the need is to try to use the same device everywhere (e.g., office, home) and for everything (e.g., work, free time). This reflects the rising concept of “Bring Your Own Device” (BYOD). In this vision, University of Bergamo decided to develop its own Android application (named MyUniBG) in order to provide to their students and staff members advanced features (e.g., information about lessons hours and course details). In this paper, we want to highlight how, thanks to the support provided by Eclipse framework, we can make a step toward the “BYOD vision”.
The aim of the tool is to ease the notification (e.g., variations in lessons hours) using Google Cloud Messaging for Android, a service that allows you to send data from your server to your users’ Android-powered device, and also to receive messages from devices on the same connection. The tool, implemented as an Eclipse RAP plug-in, will provide two main functionalities: (a) “push” information to the community of devices (communication server-client), and (b) “pop” notifications from a device and share this information with others. In this scenario, MyUniBG app will be extended in order to be the front-end for the new features
A framework for early design and prototyping of service-oriented applications with design patterns
Full text linkService-oriented computing is playing an important role in several domains. Today the biggest shift in mainstream design and programming is toward service-oriented applications. However, the service paradigm raises a bundle of problems that did not exist in traditional component-based development where abstraction, encapsulation, and modularity were the only main concerns. Due to their distributed, dynamic, and heterogeneous nature, service-oriented software applications require us to discover, document, and share new design patterns at the service- and architecture-level. Moreover, serviceoriented applications are hard to design and validate, and demand for new foundational theories, modeling notations and analysis techniques. In line to such a vision, this article presents a framework, called SCA-PatternBox, to design and prototype service-oriented applications with design patterns. The framework relies on the OASIS standard Service Component Architecture (SCA) and on SCA component implementation types, such as SCA-Java, for supporting an “implementation-oriented” approach to service-oriented architecture modeling and to the definition and instantiation of design patterns. Moreover, in order to provide formally verified design patterns, SCAPatternBox allows the formal specification and analysis of the functional behavioral aspects of a design pattern using a formal service specification language called SCA-ASM (Service Component Architecture-Abstract State Machine). As major evaluation of the framework, two case studies and lessons learned are presented. A final comparison of existing design pattern languages is also reported
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
