Change Impact Analysis (CIA) during software evolution of safety-critical systems is a labor-intensive task. Several authors have proposed tool support for CIA, but very few tools were evaluated in industry. We present a case study on ImpRec, a recommendation System for Software Engineering (RSSE), tailored for CIA at a process automation company. ImpRec builds on assisted tracing, using information...
The popular agile practice of continuous integration has become an essential part of the software development process in many companies, sometimes to the extent that delivery to customer is impossible without it. Due to this pivotal role it is an important field of research to better understand the practice: continuous integration system behavior, improvement identification and analysis of change...
Evolution in global markets for chemical and pharmaceutical goods requires new approaches in process plant design. Modularization is commonly considered as a promising approach to face the challenges of changing production environment. In order to exploit the advantages of process modularization, new structures of communication and control are required for modular process automation. Service-oriented...
Smart grid initiatives have been the subject of international discussions and are now becoming consolidated in various markets, particularly the United States, Canada, Europe and Japan. In South America, Brazilian smart grid projects are playing an important role, even though the regulatory and technological environments represent a major challenge to be overcome by electricity distribution companies...
The process of software testing in agile environments presents complexity due to the need to be performed at short time intervals. Currently, there is no consensus in literature of the best approach to deploy agile testing. The testing management is often one of the hardest steps to be adapted to these methods, due to the short time for deliveries, which reduces the time available for testing, as...
This paper discusses a common problem in industry to detect machine failures, especially in gears and bearings through vibrational analysis. Vibrational analysis is a powerful method for analyzing any machine in the industry, but this method uses expensive signal conditioning/processing devices and significant expertise for the analysis of signals in the frequency domain. In this context, this study...
This paper discusses the main problematic, misunderstandings and gaps associated with the development of self-organizing multiagent mechatronic systems. The paper reflects the authors' experience in designing and implementing Multiagent Mechatronic Systems. It also partly addresses the work developed under the FP7 IDEAS project (rated an EU FP7 success story) as a clarifying, but not unique, example...
The resources for vibrant technological research institutions in Uganda do exist in form of recyclable machine components, government funding, skilled manpower, demand for low cost technological solutions to existing problems, a large and youthful population, and Internet information resources. This paper explores a process to conduct research and orient young engineering students to conduct product...
Notwithstanding the advances in information technologies (IT) and the advances in Artificial Intelligence (AI) their concrete application in industry remains elusive. Traditional control technology is still perceived as an advantage and more intelligent systems (IT/AI supported) are envisioned as a second order layer of middle-ware mostly useful for enterprise resource planning tools. Performance...
