Título: Inyección electrónica programable. Autor(es): Madeo, Alejandro Abstract: This final integrative project in electronic engineering focuses on creating an electronic control system for combustion engine management systems, with the goal of developing a competitive product in the programmable injection market. In the Argentine market, two predominant categories of imported programmable injection products are observed; however, both present significant limitations in terms of accessibility and quality. Therefore, this project aims to address this gap by developing a solution that combines affordability with the quality and performance of high-end imported products. It is important to note that this project is owned by MC Tecnologías SAS, which has not only financed the system's development but is also responsible for its commercialization.

Título: Diseño, implementación y control de posición angular mediante rueda de reacción de un gisóscopo. Autor(es): Dal Farra, Franco Abstract: The following report deals with the design and implementation of an angular position control simulator using reaction wheels. The work was carried out as part of the Final Integrative Project for the Electronic Engineering program at the National University of Río Negro, which is a continuation of the work carried out in a supervised professional internship in conjunction with the Bariloche Atomic Center (CAB). The motivation for this work is related to satellite attitude control using reaction wheels, a system used to maintain a fixed orientation with respect to another element or reference frame outside the satellite's frame of reference. The experimental setup attempts to represent the dynamics of the attitude control problem using a reaction wheel as an actuator. The goal is to achieve a device that can be used academically to design and implement different control algorithms in practice. The first stage of the work consisted of the design of the experimental model along with the sensors, actuators, and modules that make up the complete system, such as controllers, power stage, communication stage, etc. The physical assembly of the system was completed, with operational validation through unit testing of each part. The second stage consisted of the characterization and identification of the various plant parameters, leading to the creation and validation of a mathematical model to represent it. Various experimental identification and data analysis techniques were used, seeking a correlation between the expected results and the measurements obtained. The final stage consisted of the design and implementation of different control schemes, aimed at studying the plant's constraints and proposing a robust and stable control system that meets the given requirements. Based on the measurements and results obtained, a discussion was conducted and conclusions drawn. A functional prototype was created, in which five control algorithms were implemented, designed based on the identified model, achieving results of less than 5 seconds in settling time and 5% steady-state error.

Título: Osciladores basados en resonadores microelectromecánicos MEMS. Autor(es): Cucurull, Agustín Julián Abstract: In recent decades, the massification of electronics and advances in semiconductors have driven a constant race toward miniaturization and the integration of multiple devices and sensors on a single chip. However, as the scale of these systems decreases, the technical and economic challenges become increasingly complex, leading to the search for new techniques that enable both the development and manufacturing of increasingly smaller structures. This work focuses on one of these emerging techniques, known as Fab On a Chip, and in particular, on the optimization of one of its key components: a mass sensor based on a mechanical resonator whose variation in resonant frequency allows for highly accurate measurement of small variations in the amount of a deposited material. The main objective is to develop a self-sustaining closed-loop system that allows continuous monitoring of the sensor's resonant frequency, with the aim of integrating it into the manufacturing processes of micro- and nanoscopic-scale structures and devices. To achieve this, two fundamental circuits will be designed: a phase shifter, responsible for correcting the phase shift introduced by the sensor at resonance and by the different elements of the system, and a transimpedance amplifier capable of operating with signals in the tens of nanoampere range. In addition, optimization strategies will be implemented at each stage of the system, improving both signal processing and the codes used to autonomously control the different instruments.

Título: Gamma Tracker: Instrumentación para la detección de radiación gamma en cirugía laparoscópica. Autor(es): Torletti Daniluk, Lara Agostina Abstract: This thesis presents the comprehensive development of a portable gamma radiation detection system for application in oncologic laparoscopic surgery. The work is based on a specific clinical need: to improve the accuracy of tumor tissue localization during minimally invasive procedures using positron-emitting radiopharmaceuticals such as FDG. An innovative device, the Gamma Tracker, is proposed. It consists of a detection probe based on an inorganic scintillator (LYSO or GSO) coupled to a silicon photomultiplier (SiPM), analog and digital acquisition electronics developed from scratch, embedded firmware optimized for low-power microcontrollers, and a housing designed for surgical integration, including directional tungsten shielding. This work not only demonstrates the technical feasibility of the device but also lays the groundwork for further development, consolidating a national technological solution with potential impact in nuclear medicine and surgery.

Título: Dispositivo portátil para Sistema de alambrado virtual. Autor(es): Salvo Felley, Ricardo Adrián Abstract: This work comprises the final integrative project for the Electronic Engineering program at the National University of Río Negro. It involves the development of a prototype collar for grazing animals, which allows for obtaining their geographic location and biometric parameters. This information is transmitted wirelessly to a base station, where it is processed and made available to the livestock producer or scientific institution. In turn, the system receives geographic points from the base station, generating virtual boundaries that the animal must not cross. To achieve this, different types of actuators are used to correct the animal's movement direction. The base station is part of the final integrative project completed by two other students from the same institution. Therefore, its development is beyond the scope of this document.

Título: Desarrollo de una antena de doble polarización para aplicaciones en radar meteorológico. Autor(es): Ortiz, Néstor Fabián Abstract: In this work, the design of a dual-polarized microstrip antenna for the next generation of weather radars based on antenna arrays is addressed. Only one radiating element of the antenna array is analyzed, which consists of a rectangular geometry patch antenna with low permittivity dielectric. The main difference with conventional microstrip antennas is the feeding mechanism, which consists of using directional couplers to increase its bandwidth. In addition, differential excitation is incorporated to improve the characteristics of the antenna by increasing cross-polarization rejection. The design is studied through theoretical models based on the resonant cavity model and numerical simulations in commercial software. The simulated results are compared with the experimental results obtained from the measurement of the built prototypes.
