Field Weakening Characteristics Computed with FEM-Coupled Algorithms for Brushless AC Motors
(MDPI AG, 2018)Finite Element Method (FEM) analysis tools are the most adopted in the design of brushless alternating current motors due to the advantage of considering multi-physics effects with dependencies of variables such as ... -
FlexRQC: Model for a Flexible Robot-Driven Quality Control Station
(Elsevier Ltd., 2020)As the investment on a dedicated quality control stations is not desirable for limited production batches. In general, those systems result in very optimised systems and the lack of flexibility since they are designed for ... -
Foveal Pit Morphology Characterization: A Quantitative Analysis of the Key Methodological Steps
(MDPI, 2021)Disentangling the cellular anatomy that gives rise to human visual perception is one of the main challenges of ophthalmology. Of particular interest is the foveal pit, a concave depression located at the center of the ... -
FPGA-Based Degradation and Reliability Monitor for Underground Cables
(MDPI AG, 2019)The online Remaining Useful Life (RUL) estimation of underground cables and their reliability analysis requires obtaining the cable failure time probability distribution. Monte Carlo (MC) simulations of complex thermal ... -
A Framework For Product Design Based On Semantic Attribution Process
(Taylor & Francis, 2017)Existing brands already have certain products that generate a particular experience in customer minds. Every time a customer’s interacts with of brand’s products and related touchpoints, the customer form an idea about the ... -
Framework to evaluate continuous improvement process efficacy: a case study of a capital goods company
