Research ArticleOpen accessIn the author namesAn Experimental Study on the Embedded Software Development Approach Using TI-RTOSAloysio Augusto Rabello de Carvalho, Luiz Eduardo Galvão MartinsEmbedded systems have experienced significant growth in recent years. These systems, which power a wide range of devices from smart appliances to industrial machinery, have become integral to our daily lives and industries. However, this rapid expansion introduces new challenges for developers. A critical decision involves whether to employ a Real-Time Operating System (RTOS) or to forgo it, depending on … …Journal of Computer Science, Vol. 21, Issue 6 · 17 Jul 2025 · 3,073 accessesView PDFCite
Review ArticleOpen accessIn the author namesMaintenance and Evolution Processes of Embedded Software: A Systematic Literature ReviewAloysio Augusto Rabello de Carvalho, Luiz Eduardo Galvão MartinsThe relevance of embedded systems has increased considerably due to industrial automation and the adoption of IoT and medical devices. This process demands the adaptation of software engineering techniques that involve the maintenance and evolution of software for use in embedded systems. We conducted this Systematic Literature Review (SLR) to investigate the state of the art on the topics of … …Journal of Computer Science, Vol. 21, Issue 7 · 17 Jul 2025 · 3,750 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Use of Biosensors to Analyse a Soldier’s Stress LevelJosé Miguel Martinho Silva, Ricardo A. Marques Lameirinhas et al.Currently and increasingly, biosensors are present in our daily lives, even if tendentiously and imperceptibly. As such and given their importance, the scientific community is clearly interested in making progress in this research field. This study is part of the study of biosensors using pre-gelled electrodes and was focused on the analysis of the ability to extract information on the … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 1 Mar 2024 · 4,982 accessesView PDFCite
Research ArticleOpen accessIn the author namesSimulation of Production of Anhydrous Bioethanol using Glycerol and 1-Butyl-3-Methylimidazolyl-Tetrafluoroborate in the Aspen Plus SimulatorJosé Izaquiel Santos da Silva, Lílian da Silva Félix, Mariana Martins Vieira et al.Biofuels are present in the global scenario as an energy source derived from organic biomass, representing an economic and environmental alternative. They are a renewable source of energy with low rates of pollutants emissions and, consequently, less carbon dioxide is released into the atmosphere. The obtaining of bioethanol is originated from a fermentation process, in which a multi-component mix is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 16 Jun 2021 · 7,114 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Different Cycles of Thermal Fatigue in Steel Metallurgical Aspects ASTM SA-516 Grade 60Eder Hermes Bicharra, Jorge Luis Braz Medeiros, Luciano Volcanoglo Biehl et al.The ASTM SA-516 steel has applications in compact steam boilers of low and medium temperature and pressure. Deterioration can show when exposed to high temperatures due to fuel gases burning. Failures detected by inspections done in a frequency required by standard on the boilers. Among the main failure mechanisms found in materials used in boilers, creep, corrosion, when subjected to … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,993 accessesView PDFCite
