13. Intuition and wisdom in decision making
Abstract Paper aims This article discusses the importance of intuition and wisdom for timely andsuccessful decision making and highlights the features of intuitive leaders. Originality As engineers reach higher hierarchical levels, technical knowledge must be balanced with intuition, a matter that is not addressed in their education. Research method It

16. Gestão operacional do transbordo de cana-de-açúcar: Análise do custo de reparo e manutenção
RESUMO Na colheita mecanizada de cana-de-açúcar é utilizada uma colhedora autopropelida em conjunto com uma máquina agrícola denominada de transbordo, que tem a função de transportar o produto colhido. Os custos com o corte, carregamento e transporte variam entre 30 e 60% dos custos de produção da cana-de-açúcar. Dentre os custos operacionais de m

17. Probability Analysis in Determining the Behaviour of Variable Amplitude Strain Signal Based on Extraction Segments
Abstract This paper focuses on analysis in determining the behaviour of variable amplitude strain signals based on extraction of segments. The constant Amplitude loading (CAL), that was used in the laboratory tests, was designed according to the variable amplitude loading (VAL) from Society of Automotive Engineers (SAE). The SAE strain signal was then edited

18. Cowper-Symonds parameters estimation for ABS material using design of experiments with finite element simulation
Abstract Polymers exhibit significant strain rate dependence in their mechanical strength. The impact simulations accuracy is associated with the use of mechanical properties obtained at high strain rates. These properties are often not available to engineers introducing a risk on the product development step. This paper presents a method for adjusting the p

19. Geological modeling of a stratified deposit with CAD-Based solid model automation
Abstract The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mi

20. The Challenge to Scavenge IRON from Tailings Produced By FLOTATION A New Approach: The Super-WHIMS & the BigFLUX Magnetic Matrix
Abstract Tailings recovery has been a constant challenge for most engineers. Along more than five years, GAUSTEC joined major players in the mining Industry to scavenge Iron from tailings produced by flotation making use of WHIMS (Wet High Intensity Magnetic Separation). In the early 1980s, in USA, the US 4,192,738 patent was granted with promising results.

21. Mentoring future engineers in higher education: a descriptive study using a developed conceptual framework
Abstract Mentoring research is recent and multidisciplinary and is found in mostly English speaking cultural contexts. The purpose of this study is to describe a fifty-year old mentoring practice involving faculty-mentors and engineering student-mentees, at the school of engineering of a Spanish university, a non-English speaking context. Mentoring is part o

22. Multistage Deep Drawing with Ironing of Al-killed AISI 1040 Graded Medium Carbon Steel: a Parametric Study
Analysis of multistage deep drawing with ironing was made while manufacturing of cups from 12 mm thick, 60 mm diameter circular blanks of Al-killed AISI 1040 graded medium carbon steel. Quality requirements of the steel in heat treated condition were examined in terms of tensile properties, formability characteristics, and formability limit diagram. Drawabil

23. Regional development and engineering education: an analysis of Brazil’s micro-regional scenario
Abstract Regional development is fundamental to equally develop countries. This paper focus on the micro-regional aspect of engineering education and its spillovers to understand the current impact in macro regional Human Development Indexes of Education (HDI_E) and Revenue (HDI_R). A complete analysis of official government data in all micro-regions, the nu

24. A problem regarding buoyancy of simple figures suitable for Problem-Based Learning
A machine can make three-dimensional figures that can float on different types of liquids, using for each figure always the same quantity of mass. The machine had already made spheres when the engineers intended to design other figures that reached the same depth below the surface. They tested with cubes and realized that regardless of the liquid on which fi
