13. Evaluation of the resistance of trussed slabs with steel formwork in cold formed U profile
Abstract In the last decades, the modernization in structural engineering has increased the use of steel-concrete composite and hybrid systems for slabs, when the adherence in the interface of the materials is present or not, respectively. In addition to the traditional steel deck, a similar solution for precast trussed slabs has been used for small construc

14. Analysis of the contribution of the block-soil contact in piled foundations
Abstract Geotechnical engineering has often been challenged by demands from technically and economically bold construction projects, such as that of tall buildings. The architectural requirements of these buildings have increased and concentrated the loads from structural systems without proportionally increasing plant area. New forms of using load capacity

15. METABOLÔMICA MICROBIANA: INOVAÇÕES E APLICAÇÕES
Over the past few years, metabolomics has been employed in a broad range of applications in different research fields. Microbial metabolomics has been applied in several microbiological areas, such as identification of microorganisms, cell mutations, functional gene approach, identification of unique metabolic pathways and microbial engineering, leading to a

17. 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

18. SENSITIVITY ANALYSIS FOR MODEL COMPARISON AND SELECTION IN TISSUE ENGINEERING
ABSTRACT Computational modeling has been proven to be very useful in tissue engineering over the past years. Because the model is a simplification of the experimental system, the processes accounted for in the model should be analyzed carefully. However, new and complex models are usually proposed without a clear comparison with the basic ones. In this study

19. Integrating Science, Technology, Engineering and Mathematics contents through PBL in an Industrial Engineering and Management first year program
Abstract Paper aims This paper presents teachers and students perspectives of integration Science, Technology, Engineering and Mathematics (STEM) courses contents into the first year of Industrial Engineering and Management (IEM) program through Project-Based Learning (PBL). Originality These perspectives provide strategies that IEM teachers could use to c

20. Selection of a Hyper-Elastic Material Model - a Case Study for a Polyurethane Component
Abstract The aim of this study was to select an appropriate material model for a polyurethane rail pad. The considered material was assumed to be hyper-elastic, and model selection was limited only to the Mooney-Rivlin (M-R) material models available in the MSC.Marc/Mentat system. The selection of the most appropriate material model was based on the most acc

21. Analytical determination of the vibration frequencies and buckling loads of slender reinforced concrete towers
Abstract This study focused on improving the design of slender structures with reinforced concrete (RC) telecommunication towers as the main application. Analytical procedure based on Rayleigh’s method to compute the first natural vibration frequency and the critical buckling load was development. All the nonlinearities present in the system were considere

22. USE OF GROUND PENETRATING RADAR TO STUDY SPATIAL VARIABILITY AND SOIL STRATIGRAPHY
ABSTRACT Ground Penetrating Radar (GPR) is a geophysical method that uses electromagnetic waves to study subsurface structure in different fields such as geology, agriculture and civil engineering. The wave penetration in the soil is strongly controlled by the electrical conductivity of soil components such as clay, organic matter, and water. In this study,

23. Variação da entropia total para um corpo em contato com reservatórios térmicos: o caminho da reversibilidade
Resumo A segunda lei da termodinâmica é um dos tópicos de física fundamental menos compreendidos por estudantes e profissionais de ciências exatas e engenharias, talvez devido à sua sutileza e abundância de enunciados. Neste trabalho analisamos a variação de entropia de um sistema isolado, formado por um corpo de capacidade calorífica C(T) e um ou

24. Comparação entre simulação e sistema real de vibração com dois graus de liberdade
Resumo Na engenharia, compreender corretamente os elementos que compõem os sistemas vibratórios e a física envolvida nestes é fundamental no projeto de estruturas e máquinas, por exemplo. Embora em muitos casos, no estudo de sistemas vibratórios não seja possível analisar o sistema somente com um grau de liberdade, sistemas com dois graus ou mais sã
