Study of the Main Factors Responsible for the Phenomenon of Self-Combustion Observed in Solid Biomass Waste Piles

This article discusses the causes of wood-derived biomass self-combustion. We researched technical and academic literature on chemical processes at SENAI CIMATEC. The factors influencing spontaneous combustion are microbial activity, temperature, humidity, and the concentration of O2 and CO2. Fungus and bacteria play a leading role in microbial activity, degrading organic matter and releasing toxic and flammable gases. The temperature is crucial for monitoring this phenomenon.

Cloud Computing Application for Digital Integration Between an Advanced Manufacturing Plant and a Model 4.0 Factory

Industry 4.0 is a global digitalization goal for today’s industries, and cloud computing is a solution that enables ubiquitous and convenient access to infrastructure, platforms, and services. Together with fog and edge computing, it leverages the advantages of manufacturing systems integration. This research proposes a cloud architecture to integrate an advanced manufacturing plant and a SENAI CIMATEC model factory. Before implementing this architecture, assessing whether the environment is adaptable is necessary. For this, fundamentals such as the TOE structure (Technology-Organization-Environment Framework) and the SEM model (Structural Equation Modeling) are used, which evaluate the degree of adherence for the application. As a methodological procedure for the research, a database is being modeled to serve the information flow between the systems. Therefore, adapting the environment to cloud computing is crucial to the success of digital system integration and process automation and optimization advances.

Learning Proposal for Cybersecurity for Industrial Control Systems Based on Problems and Established by a 4.0 Didactic Advanced-Manufacturing-Plant

Researches data indicate that the search for cybersecurity professionals to protect industrial control systems (ICS) in Brazil is increasing, mainly because of the rise in cyber-attacks directed at the industry. However, we observed a deficiency of professionals with the required competence in ICS cybersecurity, which involves technology-information fields (IT) and operational technology (OT). On the other hand, there is a lack of educational institutions with the right strategies for training professionals who master the technologies for ICS protection. This paper presents a strategy through procedures to address this lack by evaluating scenarios of practices for the development of competencies in ICS cybersecurity through the problem-based learning (PBL) methodology. The scenarios combine theory and practice involved in solving ICS cybersecurity problems, using PBL with the support of SENAI CIMATEC's 4.0 Advanced Manufacturing Plant (AMP).

New Approaches of JBTH

Due to the increase in the number of articles denied by the JBTH that included in their scope several areas related to engineering and bioengineering, chemistry, and technologies, but not directly linked to the health area, many highly relevant papers had to be out of the Journal. As one of the important responsibilities of the Editorial Board is to evaluate the scope of the papers, they have stressed how significant the other areas of SENAI CIMATEC advances are to scientific discovery and development and decided to extend the scope of JBTH to include papers that provide the engineerings, bioengineering, technologies, chemistry, and related areas, but not linked just for health. In this sense, we have already received many strong submissions in many fields we expected. Now, the Journal reflects the evolution we have seen. We ensure it remains relevant and interesting to our readers and researchers. We've had March and part of April issues ready for publication.However, not to lose the indexes DOI, and Crossref, the acronym, and the website remained the same, changing only the name, the editorial board, and the scope of the Journal. Therefore, the Journal is now called "The Journal of Bioengineering, Technologies, and Health (JBTH)".

SENAI CIMATEC in the Scnario of Coronavirus Pandemic

The new coronavirus pandemic has posed challenges to the health system, people, and the economy, leading to abrupt social changes. Although the negative economic impact has been huge since the pandemic was declared by the World Health Organization in March 2020, new achievements are being made by industry 4.0 focused on health. The Fourth Industrial Revolution has equipped society with highly potent tools and we must harness their capabilities, where possible, to win this fight. So, COVID-19 accelerates this process and sentences our definitive entry to the fourth Industrial Revolution. In this sense, aligned with industry 4.0, SENAI CIMATEC established a proactive position in the face of the COVID-19 pandemic, promoting research, implementing plans, activities, and actions that contemplate both the redirection of the sector’s industries to the health area, as well as the new technologies of industry 4.0. The position of SENAI CIMATEC reaffirms its commitment to society at decisive moments and ensures its efforts in health care against the pandemic.

Teaching of Ordinary Differential Equations Using the Assumptions of the PBL Method

Mathematics is of fundamental importance to any natural sciences program (be-cause it provides analytical and approximate results that can be simulated and modeled) and perhaps to other areas of human knowledge. Ordinary differential equations are especially of fundamental importance to engineering programs be-cause the modeling of all phenomena of interest for these programs involves Or-dinary differential equations solutions; at the same time, students experience diffi-culties when learning Ordinary differential equations and about their applications to real physical scenarios. In this study, the problem-based learning method was used to study a group of mechanical engineering students at the SENAI CIMATEC University Center. The study analyzes the effectiveness of Ordinary differential equations instruction given through this program using the specified methodology. To consolidate the study, Conceptual Field Theory is used together with an evaluation of the results to observe student behaviors and attitudes in re-lation to actions arising from the method. At the end of the study, a questionnaire was completed by the students, with which they evaluated the effectiveness of the teaching methodology employed.

Gameq: Software for Teaching in Chemical Engineering

The use of gamification in chemical engineering is still scarce. This paper presents a gamification-base implementation applied to a chemical engineering course of SENAI CIMATEC University Center in Salvador State/Brazil. The technique is implemented in a game software called GAMEQ. The design of the gamification framework considers the sequence that a regular chemical engineer would follow that comes from access to the industry to the design and simulation of equipment. All these steps are accomplished using the game phase idea and the student is rewarded as he increases his level in the virtual industry. The results showed that the students considered this application positive and they demonstrated more interest in the course where the tool was used.

Analysis of the tribological behaviour of an automotive engine exhaust valve and a valve seat using a newly developed high temperature workbench

The valve and valve seat work together to ensure the entry of air and combustible material, the output of combustion gases and the sealing function of the compression and combustion process. The valve is the most demanding component in high efficiency engines. To work efficiently and produce low emissions, special materials are needed. Extreme temperatures of the exhaust gases, high velocities of valves and high pressure are just some of the conditions that cause wear on the valves. The materials used in production must have good workability, low wear, good mechanical strength and good fatigue and corrosion resistance at high temperature. CCM/ITA and SENAI CIMATEC have jointly developed a workbench to simulate the durability of valves and valve seats and to enable analysis of wear resistance and by testing different parameter values. Using this workbench, some materials were tested to determine whether they can be used at high temperatures, as will be necessary in the next generation of engines. Detachments from the seat material (SAE 4340) were observed in the tests, and the detached material adhered to the valve. This phenomenon significantly increases the surface roughness of the components, and it may lead to loss of function. Thus, the tested valve material (SAE EV12 21-2 N) was more resistant to wear than the seat material.

Reducing the Development Life Cycle of Automotive Valves and Seat Valves Using a New Workbench for High Temperature Wear Testing

The trend in the automotive industry is to reduce the size of engines while increasing power. The concept of leveraging considers not only the efficiency of manufacturing a product but all consumption of energy or other natural resources during the life cycle of the product. In this process, one of the bottlenecks to more efficient engines is the exhaust valve. The valve and valve seat together perform the function of ensuring the entry of air and combustible material, the output of combustion gases and the sealing function during the compression and combustion processes. The valve is the most demanding component in high efficiency engines. To ensure the rigor of operation while providing clean burning and low emissions, the application of special materials is necessary. The extremely high temperatures of the exhaust gases, the velocities of valves and the high operating pressure are only some of the parameters that cause wear on valves. The materials used in valve production must be characterized by good workability, low wear, good mechanical strength and good fatigue and corrosion resistance at high temperatures. In this context, the CCM/ITA and SENAI CIMATEC jointly developed a workbench to simulate the durability of valves and valve seats, analyze their wear resistance and evaluate their behavior with varying parameters. This paper shows the workbench development process and a new testing method that considers the high engine operation temperatures and focuses on reducing the new material development life cycle and the emissions during the product usage life time.
