Software differs from most manufactured products because it is intangible. This characteristic makes it difficult to detect, control, and understand how it evolves. This paper presents an approach based on software visualization that can detect and externalize design evolution made in a software project during its initial development or at any further phase. By using this approach, a developer can be aware of the current state of the software as a whole and can additionally verify if the current design, also called emerging design, is evolving according to the team expectations and leader guidance, preventing problems caused by misunderstandings of the expected software solution. The approach was evaluated with free/open source software (FOSS) projects. The results indicate that the approach behaves as expected when applied to real software development projects, with minor performance bottlenecks. © 2010 The Brazilian computer Society.

This paper describes a collaborative tool, ARARA (Artifacts and Requirements Awareness Reinforcement Agents), that provides awareness in Software Development Process (SDP). Ontologies support this application for they are used by project team members when preparing the artifacts, propagating the concepts through them, and used by agents as knowledge base to retrieve information, tag the artifacts, detect changes, and search for linked artifacts that may be affected by a change on a previous artifact. This collaborative tool can improve team members awareness automatically no matter where they are geographically working, once agents are responsible for tracking and notifying requirements, or any other changes, to team members, including consequent candidates for modifications. © 2010 IEEE.

Meetings take a large amount of time, and frequently, meeting facilitators are called in to help steer the meeting in the right direction. Unfortunately, facilitation is still something of an art. To assist facilitators, the thinkLet technique has been proposed. Through the use of thinkLets, facilitators may plan the meeting beforehand, deciding which activities to perform at each point. However, designing a meeting is not an easy task, especially for novice facilitators. In this paper we present AgendBuilder, a system to assist the design of meetings, electronic or otherwise, using thinkLets and compatibility rules. The system helps facilitators select and link thinkLets together in and orderly fashion, designing the meeting in the process. © 2010 IEEE.

Business processes modeling projects are increasingly widespread in organizations. Companies have several processes to be identified and modeled. They usually invest much in hiring expert consultants to do such job. However, they still find no guidelines to help them estimate how much a process modeling project will cost or how long this will take. We propose an approach to estimate the effort required to conduct a BPM project and discuss results obtained from over 50 projects in a large Brazilian company.

The main knowledge management challenges are to capture, store and reuse contextual knowledge generated during interactions that occur daily in an organization. In this paper, we propose an activity context-aware architecture to support knowledge management in working processes. The required features for this architecture are processing, reasoning and sharing contextual knowledge involving information about activities performed. We also present results from evaluation of our proposal - A-CoBrA - for a specific domain. © 2010 IEEE.

Complexity and dynamism of day-to-day activities in organizations are inextricably linked, one impacting the other, increasing the challenges for constant adaptation of the way to organize work to address emerging demands. In this scenario, there are a variety of information, insight and reasoning being processed between people and systems, during process execution. We argue that process variations could be decided in real time, using context information collected. This paper presents a proposal for a business process line cycle, with a set of activities encapsulated in the form of components as central artefact. We explain how composition and adaptation of work may occur in real time and discuss a scenario for this proposal.

Real time rendering of three-dimensional scenes in high photorealistic detail is a hard task, such as in the Ray Tracing rendering algorithm. However, parallel implementations of Ray Tracing have been enabling real time performance, as the algorithm is embarrassingly parallel. Thus, a custom parallel design in hardware is likely to achieve an acceptable 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 acceptable rendering performance.

Weightless Artificial Neural Networks have proved to be a promising paradigm for classification tasks. This work introduces the WANN-Tagger, which makes use of weightless artificial neural networks for labelling Portuguese sentences, tagging each of its terms with its respective part-of-speech. A first experimental evaluation using the CETENFolha corpus indicates the usefulness of this paradigm and shows that it outperforms traditional feedforward neural networks in both accuracy and training time, and also that it is competitive in accuracy with the Hidden Markov Model in some cases. Additionally, WANN-Tagger shows itself capable of incrementally learning new tagged sentences during runtime.
