The increase in biofuel production and consumption is driven by the scarcity of natural resources and climate change. Incentive policies, such as mandatory mixing targets, have been adopted in many countries to address these challenges. Bioenergy plays a crucial role in mitigating climate change. This work evaluates its evolution and proposes measures to make it more sustainable in Brazil. Studies were prioritized in the Center-South region of Brazil, the largest producer of sugar cane, and it was concluded that the production of bioelectricity from sugar cane has gained prominence and recognition since its emergence. The efficient use of raw materials, the adequate and effective use of bagasse and the consequent increase in the industry's overall yield are fundamental aspects in this process. This synergy not only boosts the production of clean and renewable energy, but also contributes to the environmental and economic sustainability of the sugar and alcohol sector.

In addition to this interest, both the use of software for desing and structure optimization are subjects that are gaining relevance in metallic structures, with competitive and safe solutions as long as they are well evaluated. In this context, this work aims to carry out an analysis of the elements that make up the use of software for the design of structural elements and their relationship with the most relevant theoretical projects in Engineering, when applied in a company that designs, manufactures and assembles metallic structures.

Among them, there is turning, commonly used to manufacture cylindrical parts such as axles, cylinder heads, engine block machining, valve controls and crankshafts. The quality of the machining is directly related to the surface finish of the part, which can be measured using the parameter of the analysis of the vibrations that occur during a normal turning process. High levels of vibration can lead equipment to fatigue, and consequent breakdown, which can cause production losses, service material supply problems. The objective of this work is to monitor the vibrational movements during the turning of low carbon alloys. For such analyzes, two sensors were used for data acquisition, the Arduino, which has a low cost and the piezoelectric sensor, which is more expensive but more accurate in its data acquisitions. Several tests are carried out so that the Arduino board can collect sufficiently reliable data, but it is shown throughout the process that it is unable to generate the necessary data, thus requiring a board with better quality.

Autor(es): Assunção Jr., José Maurício Beira de Primeiro Orientador: Dias, Renato Jayme Abstract: The work has three main objectives. The first is to know the operation of combustion vehicles in a deeper way. This knowledge should encompass the entire part of electronic injection for possible use together with electric motors. Sensor signals, actuator commands and motor cycles can be used for the final purpose. The second objective is related to the electromagnetic behavior of the switch reluctance machine. It will be shown all the advantages, disadvantages and constructive characteristics. Finally, three machines will be dimensioned with variable reluctance that unites the knowledge studied in these first two parts. This dimensioning will be carried out in order to have nominal characteristics with the possibility of using the electric motor together with the combustion engine of the vehicle studied.
