This laboratory will provide infrastructure to INES projects that are coordinated by the UFRN research group, ForAll.

  • INES will be at SEKE 2010

    Publicado em May 14th, 2010Uncategorized

    The INES project will be present in The 22nd International Conference on Software Engineering and Knowledge Engineering (SEKE 2010)  through the regular paper “A Constrained Particle Swarm Optimization Approach for Test Case Selection”, authored by Luciano S. de Souza, Ricardo B. C. Prudêncio e Flávia de A. Barros.

    This work was developed inside the project Tests Generation, Selection, Prioritization and Processing Product Line — in Portuguese, Linhas de Produtos de Geração, Seleção, Priorização e Processamento de Testes. Its abstract can be read bellow:

    “Automatic Test Case selection is an important task to improve the efficiency of Software Testing. This task is commonly treated as an optimization problem, whose aim is to find a subset of test cases (TC) which maximizes the coverage of the software requirements. In this work, we propose the use of Particle Swarm Optimization (PSO) to treat the problem of TC selection. PSO is a promising optimization approach which was not yet investigated for this problem. In our work, PSO was used not only to maximize coverage of requirements, but also to consider the cost (execution effort) of the selected TCs. For this, we developed a constrained PSO algorithm in which execution effort was treated as a constraint in the search, whereas the requirements coverage is used as the fitness function. We highlight that, although execution effort is an important aspect in the test process, it is generally neglected by the previous work that adopted search techniques for TC selection. In experiments performed in different test suites, PSO obtained good
    results when compared to other search techniques.”

  • INES at FTfJP’10

    Publicado em May 11th, 2010Publications

    The paper “Refactoring and Representation Independence for Class Hierarchies [Extended Abstract]”, authored by Leila Silva, David Naumann and Augusto Sampaio,  has been accepted in the 12th Workshop on Formal Techniques for Java-like Programs (FTfJP’10), a traditional workshop of the 24th European Conference on Object-Oriented Programming (ECOOP 2010). This work summarizes some results on data refinement in the context of the project Evolution and Refactoring Tools. 

  • SEKE 2010 – new results from the collaboration between INES Context Group and UEM

    Publicado em May 7th, 2010Publications

    The collaboration between the INES Context Group and the Universidade Estadual do Maringá (UEM) brings new results with the acceptance of the paper entitled “A Context Conceptual Model for a Distributed Software Development Environment” in the 22nd International Conference on Software Engineering and Knowledge Engineering (SEKE’2010), which occurs in July 1-3, 2010, San Francisco, USA.

    The paper describes a  conceptual  model  focused on contextual information for DiSEN, a distributed software engineering  environment.  Main  contributions  found  on  the paper  are:  (i)  the  identification  of  a  set  of  information  that composes environment entities context ; and (ii) the definition of a model that facilitates domain semantics comprehension, reducing communication gaps.”

    This paper is a result of the Master Thesis in Computer Science of Ana Paula Chaves, advised by Prof. Elisa Huzita, at UEM. This work uses the context framework for designing context-sensitive systems, proposed by Prof. Vaninha Vieira (UFBA), during her PhD work (UFPE). This work reinforces the research collaboration between UEM, UFBA and the UTFPR in the area of context-sensitive systems for the domain of Distributed Software Development.

    The INES Context Group is related to the project “Models, Processes and Tools for the Development of Context-Sensitive Systems”, in portuguese “Modelos, Processos e Ferramentas para o Desenvolvimento de Sistemas Sensíveis ao Contexto”.

  • INES at SEKE 2010

    Publicado em May 6th, 2010Uncategorized

    The INES project will be present in The 22nd International Conference on Software Engineering and Knowledge Engineering (SEKE’2010) through the regular paper “A Visual Bug Report Analysis and Search Tool“, authored by Carlos Eduardo Albuquerque da Cunha, Yguaratã Cerqueira Cavalcanti, Paulo Anselmo da Mota Silveira Neto, Eduardo Santana de Almeida and Silvio Romero de Lemos Meira.

    This work was developed inside the project An Investigation of Methods, Processes, Tools, and Metrics for the Development of Software Product Lines (SPL) — in portuguese, Uma Investigação de Processos, Ferramentas e Métricas para o Desenvolvimento de Linhas de Produto de Software.

    The SEKE conference “aims at bringing together experts in software engineering and knowledge engineering to discuss on relevant results in either software engineering or knowledge engineering or both. Special emphasis will be put on the transference of methods between both domains.”

  • INES at SBRC 2010

    Publicado em May 4th, 2010News

    INES researchers had a paper accepted at SBRC’2010 (Brazilian Symposium on Computer Networks and Distributed Systems), Gramado, Rio Grande do Sul, Brazil, May 2010. Fernando Castor, one of the members of INES and co-author of the paper will be presenting it in Gramado between May 24th and May 28th.

    Publication’ details are:

    Joas E. de Souza and Fernando Castor. Um Detector de Defeitos Cumulativo Baseado em uma Abordagem Difusa. In Proceedings of the 28th Brazilian Symposium on Computer Networks and Distributed Systems. Gramado, Brazil, May 2010.

    Abstract: Failure detectors are fundamental components of large-scale distributed systems. A failure detector must perceive node crashes promptly adapting to changing network conditions. In addition, it has to be accurate and avoid wrong suspicions, since the latter result in unnecessary processing. Moreover, failure detectors should, ideally, have modest requirements in terms of memory consumption and processing time. This paper presents an accrual and fuzzy failure detector (ACD). The ACD employs ideas from Fuzzy Logic and outputs a suspicion level on a continuous scale. Furthermore, the ACD requires less resources than other detectors.
