13. RELIABILITY-BASED MULTI-OBJECTIVE OPTIMIZATION APPLIED TO CHEMICAL ENGINEERING DESIGN
ABSTRACT Chemical engineering optimization represents a significant challenge due to the complexity of the mathematical models that are frequently required in this area. These models are normally associated with nonlinear equations that represent mass, energy, and momentum balances, which are submitted to physical, constitutive, environmental, and design lim

14. Methods for blood group antigens detection: cost-effectiveness analysis of phenotyping and genotyping
Abstract Background Alloimmunization is a major problem in transfusion practice due to the clinical complications of the patients and the difficulty of choosing a unit of compatible blood product. Serological methods are widely used in blood banks, but they not always determine the phenotype. Thus, genotyping is an important complement to the serology tool

15. Strut-and-tie models for linear and nonlinear behavior of concrete based on topological evolutionary structure optimization (ESO)
Resumo A busca por sistemas resistentes representativos para estrutura de concreto requer profundo conhecimento sobre seu comportamento mecânico. Os modelos de bielas e tirantes são procedimentos clássicos utilizados no dimensionamento do concreto armado onde existem concentrações de tensão, as chamadas regiões descontínuas da estrutura. No entanto,

20. Reliability of Thyroid Imaging Reporting and Data System (TI-RADS), and ultrasonographic classification of the American Thyroid Association (ATA) in differentiating benign from malignant thyroid nodules
ABSTRACT Objective Ultrasonography (US) is the best diagnostic tool for initial assessment of thyroid nodule. Recently, data reporting systems for thyroid lesions, such as the Thyroid Imaging Reporting and Data System (TI-RADS) and American Thyroid Association (ATA), which stratifies the risk for malignancy, have demonstrated good performance in differentia

21. Aircraft Preventive Maintenance Data Evaluation Applied in Integrated Product Development Process
ABSTRACT: Initial Maintenance Review Board Report (MRBR) uses in service operation experience as a reference to define maintenance tasks intervals. However, in general, there is no structured data to compare systems performance and provide useful information to the analysts' decision-making. Even when engineering judgment is based on certification process, s

24. La representación de documentos y autoridades archivísticas: una mirada desde la perspectiva de la normalización
ABSTRACT Nowadays, the archival science is going through a big changes in its conception as science. As a result, the discipline has gone from the inactivity in the normalization of their tasks to the regulatory action of most its processes. In the late twentieth century, institutions such as the International Council on Archives and prestigious associations
