One widely accepted definition of software architecture is that it is a composition of a set of architectural design decisions. Hence, designing a software architecture is a decision-making process. Agile methods drastically changed the way of designing a software architecture. In projects using agile methods (e.g. Scrum), making architectural design decisions is not the responsibility of a single person, but rather the whole development team. Despite the popularity of such methods in the industry, little research exists on how to make these decisions from the perspective of a group effectively. Current techniques usually focus on the identification of quality attributes and design alternatives, not addressing the whole decision-making process. The quality of decisions directly reflects the quality of the software architecture. Therefore poor decisions lead to bad software architectures. In this paper, we discuss current research on group decision-making in software architecture and the proposal of a combination of concepts from two architecture definition methods into a single approach that can be used in agile projects and addresses the most critical concerns of group decision-making. This proposal is part of a master's research project.
- Artigo de eventoComparison of Bio-Inspired Algorithms from the Point of View of Medical Image Segmentation(2018) Wachs Lopes G.A.; Beltrame F.S.; Santos R.M.; Rodrigues P.S.© 2018 IEEE.As new technological challenges depending on the computational performance of bio-inspired algorithms emerge, the demand for more efficient heuristic solutions grows up at same rate. Specifically, the medical field is one of the most challenging, due to the fact of the pre-processing steps, such as multilevel segmentation of color spaces, require greater precision. Thus, many algorithms inspired by natural behavior have emerged successfully aiming to find approximate solutions compatible with optimal ones, but with much higher performance in terms of computational time. Although they perform well, some of these newer algorithms have not yet been analyzed from their practical applicability in one or more medical databases. This paper presents a comparative study from a practical point of view of three of these new algorithms: Cuckoo Search (CS), KH (Krill Herd) and EHO (Elephant Herd Optimization). Our results suggest that these three algorithms are compatible in terms of performance in medical databases, but with EHO showing the best performance among all three.

M.; Aquino-Junior P.T.© 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.For the first time, the HERA robot won the RoboCup@Home in the Open Platform League in Bangkok, Thailand. This robot was designed and developed by the RoboFEI@Home team, considering all mechanical, electronic, and computational aspects. It is an Open League platform capable of performing autonomous tasks in home environments, in addition to human-robot interaction, collaborating with people who share the same environment. In this edition of the competition, the platform presented advances in the methods of interacting with people and social navigation. Interaction with people and objects is supported by image segmentation processes, enhancing environment perceptions and people recognition during tasks.
- Artigo de eventoThe Inclusive Potential of Educational Robotics(2022-10-18) CANET, A. M. D.; Flavio Tonidandel© 2022 IEEE.Educational Robotics favors the development of reasoning, teamwork and the socialization of knowledge. In this work, using this educational technology as a learning mediator, its inclusive potential for students with disabilities in elementary school questioned. The objective of this study is verify the inclusive potential of educational robotics and what are the difficulties the robotics teachers present in the inclusion of students with disabilities. This research is qualitative and quantitative. It involves a bibliographic research and a questionnaire answered by the Professor of Support to Pedagogical Projects of Educational Technologies (PAPP TEC) of the Municipal Schools of São Bernardo do Campo. The questionnaire used the free Google Forms tool. The multiple-choice answers received statistical treatment and the open question analyzed using Bardin's content analysis. In the questionnaire and in the semi-structured interview, the teachers pointed out the need for training actions, collaborative action by support professionals (Technical Guidance Team and specialist teachers in the areas of disabilities) and access to assistive technology for the development of the inclusive potential of robotics.
- Artigo de eventoCase Study of student with neuromotor disability in the Educational Robotics project in Elementary School I(2022) Canet A.M.D.; Tonidandel F.© 2022 IEEE.In this investigation, using educational robotics as a mediator of learning, its inclusive potential for students with severe neuromotor impairment in elementary school was questioned. The objective of this work is to list the strategies and assistive technologies needed for children diagnosed with chronic non-evolving encephalopathy, with a motor condition of tetraparesis, who are attending Elementary School I, to be able to perform the activities proposed in the Educational Robotics classes. The hypothesis raised is that with the necessary adaptations the student can improve their functional performance and carry out school activities with greater autonomy and independence. This research is qualitative. It involves two phases: bibliographic research and a case study involving two elementary school students diagnosed with non-progressive chronic encephalopathy, with a motor condition of tetraparesis. The following used for the analysis of functional performance: the filming of the child before and after the use of the adaptations, the PEDI (Pediatric Evaluation of Disability Inventory), the ICF (International Classification of Functioning) and the PAPP TEC semi-structured interview. It concluded that virtual robotics through a software with screen scanning and interconnected boards of communication proved a possibility for adapting children who do not have conventional access to the assembly and programming parts of the robot, especially those with severe neuromotor disability who obtain the adaptive switch. With the use of adaptations, the student showed an improvement in her occupational performance and made it possible for her to participate in activities as a protagonist and not just as an observer.
