26th Brazilian Symposium on Software engineering, SBES 2012

作者： Schots, Marcelo Werner, Cláudia Mendonça, Manoel Systems Engineering and Computing Program COPPE/UFRJ Federal University of Rio de Janeiro Rio de Janeiro Brazil Computer Science Department Federal University of Bahia Rio de Janeiro Brazil

ISBN: (纸本)9780769548685

The creation of tools, techniques and methodologies to support the manipulation of large data sets has been receiving special attention of both scientific and industrial communities, in order to discover new ways of dealing with the underlying information, including learning purposes, identification of patterns, decision making support, amongst others. However, making use of computing resources to enhance awareness and understanding of software information and the software itself is still a challenge in software/systems engineering, since it involves the identification of suitable mechanisms, adequate abstractions, and studies on stimulation of the human perceptive and cognitive abilities. This paper presents some of the challenges in this context, based on current trends of software development lifecycle, program comprehension, and software engineering education. At the end, a special focus is given on ongoing research on using and improving current mechanisms for supporting software reuse practices and software comprehension in general. © 2012 IEEE.

Complexity and dynamism of day-to-day activities in organizations are inextricably linked, one impacting the other, increasing the challenges for constant adaptation on the way to organize work to address emerging demands. Market is demanding systems that are aware of organizations processes and able to evolve and adapt to new situations in everyday working activities. We argue that flexibility in processes could be managed in real time, by PAIS (Process-aware Information systems), using context information collected in the work environment. This paper proposes CGAdapt, a context management architecture approach that aims to improve and automate dynamic process adaptation. We explain how process adaptation may occur in real time through an existent scenario using this proposal and discuss the value of context-awareness to reason about process alternative adaptations in a goal oriented approach. © 2012 IEEE.

18th International Conference on Collaboration and Technology, CRIWG 2012

Collaboration is important for productivity, quality, and knowledge sharing in software development. In this context, the use of social networks analysis can help to track the level of collaboration in a development project. In this work, an exploratory study was conducted, in the context of free/open source software, using EvolTrack-SocialNetwork tool, to investigate collaboration in software teams. The preliminary results indicate a potential to increase one's ability to understand the course that the collaboration is taking. © 2012 Springer-Verlag.

Business processes modeling projects are increasingly widespread in organizations, which usually invest much in hiring expert consultants to do such job. These consultants come from various organizations, and have different experiences on how to perform the same activity. This paper analyzes how human-related capabilities influence the effort required to conduct a business process modeling project and discusses the results obtained from about 50 projects executed in a large Brazilian company. © 2012 Taylor & Francis Group, London.

An efficient parallel architecture for ray-tracing

An efficient parallel architecture for ray-tracing

引用

作者： Nery, Alexandre S. Nedjah, Nadia França, Felipe M.G. LAM - Computer Architecture and Microeletronics Laboratory Systems Engineering and Computer Science Program COPPE Universidade Federal Do Rio de Janeiro Rio de Janeiro RJ Brazil Department of Electronics Engineering and Telecommunications Faculty of Engineering Universidade Do Estado Do Rio de Janeiro Rio de Janeiro RJ Brazil

Real time rendering of three-dimensional scenes in high photorealistic details is a hard task, such as in the ray tracing rendering algorithm. In general, the performance achieved by a sequential software-based implementation of ray tracing is far from satisfactory. However, parallel implementations of ray tracing have been enabling reasonable real time performance, as the algorithm is embarrassingly parallel. Thus, a custom parallel design in hardware is likely to achieve an even higher performance. In this paper, we propose a hardware parallel architecture capable of dealing with the main desirable features of ray tracing, such as shadows and reflection effects, imposing low area cost and a promising rendering performance. Such architecture, called GridRT, is based on the Uniform Grid acceleration structure and is intended to deliver massive parallelism through parallel ray-triangle intersection tests as well as parallel processing of many rays. A hardware implementation of the proposed architecture is presented, together with some performance results and resources requirements. The rendering is reduced by 80% using a grid configuration of eight processing elements. © Springer science+Business Media, LLC 2011.

Software process definition is a complex, time consuming and error prone activity. Such activity can be facilitated by a process reuse strategy. This strategy can be implemented through a context-based process line approach. Based on the data from this approach and following its systematic, this work presents a proposal to software processes composition and optimization (COMPOOTIM). The purpose is to support the project manager's decisions and automate the composition of a project specific process. COMPOOTIM optimizes the suggestion of processes to the context of a particular project. A usage scenario for process selection exemplifies the use of COMPOOTIM.

Introducing Software Process Tailoring to BPMN: BPMNt

Introducing Software Process Tailoring to BPMN: BPMNt

International Conference on Software and System Process (ICSSP)

作者： Raquel M. Pillat Toacy C. Oliveira Fabio L. Fonseca Systems Engineering and Computer Science Program-PESC / COPPE Federal University of Rio de Janeiro Rio de Janeiro Brazil

BPMN 2.0 is a widely used notation to model business process that has associated tools and techniques to facilitate process management, execution and monitoring. As a result using BPMN to model Software Development Process (SDP) can leverage on the BPMN's infrastructure to improve SDP quality. Nevertheless, when using BPMN to model Software Processes one can observe the lack of an important feature: means to represent process tailoring. This article introduces the BPMNt, a conservative extension to BPMN that aims at aggregating a tailoring representation mechanism as the one found at SPEM 2.0. BPMNt uses the extensibility classes already present in the BPMN meta-model. Our work also presents an example to illustrate the approach.

International Conference on computer Supported Cooperative Work in Design

作者： Talita da Cunha Mattos Flávia Maria Santoro Kate Revoredo Vanessa Tavares Nunes Postgraduate Information Systems Program UNIRIO Rio de Janeiro Brazil COPPE/PESC-Systems Engineering and Computer Science Program UFRJ Rio de Janeiro Brazil

Business processes are dynamic and constantly evolving. Contextual elements that had not yet been identified and represented can arise and influence the execution of each process instance in diverse manners. In this scenario, the identification of these elements is considered of great importance. This paper proposes a formalism for context associated with business processes that intends to identify the situation of an activity in order to subsidize decisions to be taken within the execution of a process.
