Abstract: The recent advancements in natural language processing (NLP) have introduced novel artificial intelligence models for data classification, extending their scope to analyzing brain signals acquired via electroencephalogram (EEG). Among these developments, the transformer architecture, which has become available in recent years, has provided researchers with a powerful model to Leia mais…
Abstract: Agile approaches and practices have become pervasive in the software industry. The principles of this methodology consistently prioritize technical excellence and the advancement of sustainable development, leading to the creation of high-quality code that aims to minimize Technical Debt (TD). However, the agile methodology does not guarantee the absence Leia mais…
Abstract: This text presents some of the state of the art and technical and metrological aspects of 3D optical scanners (also commonly called digitizers). Optical digitizers create point clouds from data on an object’s surface, which are used to build digital three-dimensional models. It has become essential equipment for dimensional Leia mais…
Abstract: This study comprehensively investigates a carbon fiber-reinforced polyphenylene sulfide (CF/PPS) composite through tensile, fatigue, interlaminar shear strength (ILSS), dynamic mechanical tests (DMA), and also fractographic analysis. Prepared via hot compression molding, the CF/PPS composites exhibit a consistent quality. Tensile tests show an elastic modulus of 37.2 ± 0.2 GPa Leia mais…
Abstarct: It is particularly important to investigate the mechanical performance of carbon fiber (CF) reinforced polyamide 6 (PA6) composites used for automotive and aerospace applications, where diffused moisture of the environment may potentially weaken the material over time. In this work, CF/PA6 composites were subjected to two different types of Leia mais…
Abstract: Prepregs are highly dependent on the resin, its chemical composition, and physical properties. Resin is the perishable part of prepreg materials and usually requires controlled storage, otherwise, its processability and properties may be affected. Oven curing prepregs are recognized to have longer life out of the freezer than those Leia mais…
Abstract: Soil contamination and its impact on human health are growing concerns worldwide due to anthropogenic activities, as soil plays a central role in the absorption of pollutants, including petroleum hydrocarbons. Conventional soil remediation techniques can have signifcant environmental impacts. Sustainable approaches are therefore needed, and bioremediation has emerged as Leia mais…
Resumo: Laboratórios de calibração acreditados são aqueles que foram e são avaliados periodicamente para o atendimento integral à norma ABNT NBR ISO/IEC 17025. Um serviço realizado por um laboratório acreditado possui reconhecimento regional e internacional com base em acordos de reconhecimento mútuo. Considerando que a tarefa de buscar o laboratório Leia mais…
Resumo: Este artigo tem como objetivo descrever brevemente as diretrizes de Boas Práticas de Fabricação (BPF) para medicamentos estéreis no Brasil (Instrução Normativa IN 35/2019), e fazer uma breve explanação comparada com as alterações já definidas nas diretrizes do EU GMP Anexo 1 da Comissão Europeia e PIC/s. De acordo Leia mais…
