To this end, the open-source finite element method (FEM) software FEMM (Finite Element Method Magnetics) is employed, together with the PyFemm library, which allows automation of simulation routines and facilitates machine modeling, and the Python language, used for processing and analyzing the obtained results. The adopted methodology is based on the stator of a 2 HP induction machine. In this context, the machine's original rotor is replaced by reluctance rotors with distinct geometries, aiming to optimize torque and torque ripple. Thus, the performance of each topology is expected to be evaluated, identifying the most efficient geometry for application in synchronous reluctance machines.

Consequently, there is a high demand for medical care, even though patients find themselves in different phases of the disease (febrile, critical, or recovery). Therefore, it is fundamental to develop new strategies using telemedicine to relieve the healthcare system. The objective of this study was to develop a mobile telemonitoring application, named TeleDengue, focusing on initial screening, symptom tracking, and informative modules. The methodology was based on requirements gathering through forms applied to patients and medical professionals to identify the real needs of users, in addition to relying on Design Thinking principles for system idealization. Development was carried out using a low-code strategy, utilizing the FlutterFlow platform integrated with the Firebase database for the secure storage of clinical information. As a result, the application was structured into four main sections: symptom tracking, which issues alerts based on the severity of the selected symptoms; dengue information, featuring self-care and disease protection guidelines; care facilities in the city of Uberlândia, providing addresses and contact phone numbers; and symptom history, which offers automated charts and reports of the disease's progression to assist in future medical consultations. In conclusion, TeleDengue features functional tools that can assist in dengue care, with the potential to optimize patient flow, reduce the burden on healthcare units, and support patients in their recovery at home.

The proposal demonstrates how technologies associated with Industry 4.0 can be integrated with traditional industrial automation systems. The study covers the development of the simulation’s three-dimensional models using the Autodesk Inventor software, the implementation of mechanical behaviors and dynamic processes in the Unity software, the development of the virtual PLC and control logic in Ladder language using the CODESYS software, as well as the configuration of Modbus TCP communication between the environments. In addition, the application was developed for execution in virtual reality and validated using the Meta Quest 3S headset. The conducted tests allowed the identification of performance bottlenecks and improvement opportunities; however, overall, the system achieved the proposed objectives, proving to be a viable solution for fault identification, control validation, and analysis of industrial processes in an interactive three-dimensional environment with low experimental cost.
