Studies that lead to the development of more accessible and low-cost electronic technologies and devices for biomechanical and biomedical analysis applications are becoming increasingly needed. In this work, the development of a multiaxial extensometric force platform will be addressed, aiming to improve the sensitivity and reduce the costs of existing platforms. Additionally, this platform can be used for analysis and characterization of flight time and postural characterization of volleyball athletes. As a result, a functional and easily produced prototype was created, due to the processes used (final cost of the developed platform—USD$100). The interfaces of visualization and analysis of the device functions were designed in LabView. The purpose of the experiments is to perform flight analysis of athletes, and all functions designed for the platform strength and endurance are focused on that same purpose. The prototype’s functions were evaluated by applying loads from 700 to 1000 N (Newtons) and its future integration with other instruments such as the surface electromyography (EMG) and an electrocardiogram (ECG) is expected to form an instrument kit that improves the characterization of studies of balance, strength and muscular endurance.
The development of studies, projects, and technologies that contribute to the understanding and preservation of plant biodiversity is becoming highly necessary, as well as tools and software platforms that enable the storage and classification of information resulting from studies on biodiversity. This work presents LeafLive-DB, a software platform that helps map and characterize species from the Brazilian plant biodiversity, offering the possibility of worldwide distribution. Developed by Brazilian and Peruvians researchers, this platform, which is available in its first version, features some functions for consulting and registering plant species and their taxonomy, among other information, through intuitive interfaces and an environment that promotes collaboration and data and research sharing. The platform innovates in data processing, functionality, and development architecture. It has ten thousand registers, and it should start to be distributed in partnership with schools and higher education institutions.
Teaching programming courses can be considered challenging for those who teach the subject. The difficulty of programming together with the lack of knowledge when dealing with students who are in the first year of studies makes the challenge even greater. In the career of Electronic Engineering of the National University of San Agustín the use of Arduino has been incorporated to teach the main programming concepts oriented to electronics. Students program components aimed at solving problems related to their profession. The first results have shown the effectiveness in the use of Arduino. We believe that our experience can be replicated not only in other Electronic Engineering careers, but in any engineering that I have programming courses guiding the development of the projects to the relevant contexts of each engineering. Abstract-La enseñanza de los cursos de programación pueden ser considerados desafiantes para los que enseñan la materia. La dificultad propia de la programación junto con la falta de conocimiento cuando se trata de alumnos que se encuentran en el primer año de estudios hace que el desafío sea aún mayor. En la carrera de Ingeniería Electrónica de la Universidad Nacional de San Agustín se ha incorporado el uso de Arduino para enseñar los principales conceptos de programación orientados a la electrónica. Los alumnos programan componentes orientados a solucionar problemas relacionados a su profesión. Los primeros resultados han mostrado la efectividad en el uso de Arduino. Creemos que nuestra experiencia puede ser replicada no sólo en otras carreras de Ingeniería Electrónica, sino en cualquier ingeniería que tengo cursos de programación orientando el desarrollo de los proyectos a los contextos pertinentes de cada ingeniería
