1. Tacit knowledge in unstructured decision process
Abstract Purpose This paper aims to identify the expressions and flows of tacit knowledge in the unstructured decision process. In this type of process, decision-makers use not only the explicit knowledge but also aspects such as intuition, experience and other forms of tacit knowledge. The research developed a qualitative approach, through a study of multi

2. “The interviews were transcribed”, but how? Reflections on management research
Abstract Purpose In qualitative research, it is recurrent to conduct data collection through interviews, which must be first transcribed for the data to be analyzed. Although there is a relationship between the stages of the interview and the data analysis, the link between them (i.e. the transcription) seems to be a neglected methodological procedure. This

3. Guide for Recommended Practices to Perform Crack Tip Opening Displacement Tests in High Strength Low Alloy Steels
Abstract: Fracture mechanics approach is important for all mechanical and civil projects that might involve cracks in metallic materials, and especially for those using welding as a structural joining process. This methodology can enhance not only the design but also the service life of the structures being constructed. This paper includes detailed considera

4. ADVANCED CONTROL OF A COMPLEX CHEMICAL PROCESS
Abstract Three phase catalytic hydrogenation reactors are important reactors with complex behavior due to the interaction among gas, solid and liquid phases with the kinetic, mass and heat transfer mechanisms. A nonlinear distributed parameter model was developed based on mass and energy conservation principles. It consists of balance equations for the gas a

6. Optimizing the control system of cement milling: process modeling and controller tuning based on loop shaping procedures and process simulations
Based on a dynamical model of the grinding process in closed circuit mills, efficient efforts have been made to optimize PID controllers of cement milling. The process simulation is combined with an autoregressive model of the errors between the actual process values and the computed ones. Long term industrial data have been used to determine the model param

7. Recuperação de enxofre elementar em reatores microaerados / Sulfur recovery in micro-aerobic reactors
The occurrence of biological sulfate reduction results in the formation of unwanted hydrogen sulfide, which can be removal under oxygen-limiting conditions. Detailed knowledge of this process remains unclear and the micro aeration process was prevented by technological limitations. For these reasons, the chemical and biological oxidation of sulfide was studi

8. Modeling, simulation and identification for control of tandem cold metal rolling
This paper describes a modeling procedure for tandem cold metal rolling, including the linearization step and system identification for control. The tandem cold rolling process is described by a mathematical model based on algebraic equations developed for control purposes and empirical relations. A state-space model is derived and detailed analyses in open

10. Recent trends in the modeling of cellulose hydrolysis
This work reviews recent trends in the modeling of cellulose hydrolysis, within the perspective of application of kinetic models in a bioreactor engineering framework, including scale-up, design and process optimization. From this point of view, despite the phenomenological insight that mechanistic models can provide, the expectation that more detailed appro

11. Process analysis and optimization mapping through design of experiments and its application to a polymerization process
The technique of experimental design is used on an ethylene polymerization process model in order to map the feasible optimal region as preliminary information for process optimization. Through the use of this statistical tool, together with a detailed deterministic model validated with industrial data, it is possible to identify the most relevant variables
