    Inteligencia artificial y aprendizaje automático para prevención de ataques DDoS en dispositivos IoT

    No full text
    "Los dispositivos IoT son cada vez más comunes en nuestro día a día, y la implementación de redes 5G hará que esta tecnología crezca aún más. Cuantos más dispositivos haya conectados a la red más dependeremos de estos y más se nos complicará la vida cuando estos sistemas no estén disponibles. Por ejemplo, dispositivos con sensores que transmiten el estado de producción de una fábrica y según esos datos se realiza una acción determinada no puede dejar de funcionar porque se arruinará toda la cadena de producción o, aún más importante, dispositivos médicos que rastrean signos vitales y alertan al personal de salud sobre cualquier cambio importante deben estar disponibles las veinticuatro horas del día porque la vida de un paciente depende de ello. Es por esto, que este trabajo analiza técnicas de inteligencia artificial utilizadas para la prevención de ataques informáticos DDoS (Distributed Denial-of-Service) en dispositivos IoT que atentan contra la disponibilidad de los datos.""IoT devices are becoming more and more widespread in our daily lives, and the implementation of 5G networks will make this technology more pervasive. As more devices are connected to the network, more we will depend on them and consequently devices’ reliability becomes more important than ever. For example, devices with sensors that transmit the production status of a factory and according to that data a certain action is carried out cannot stop working because the entire production chain will be ruined or, even more importantly, medical devices that track vital signs and alert health personnel of any important changes must be available twenty-four hours a day because a patient's life depends on it. Hence, this work explores artificial intelligence techniques used to prevent DDoS (Distributed Denial-of-Service) computer attacks on IoT devices that threaten data availability, which is one aspect that can disrupt these services and that affects is availability."Trabajo Final Ciencia de Datos (especialización) - Instituto Tecnológico de Buenos Aires, Buenos Aires, 202

    Spatial repellents transfluthrin and metofluthrin affect the behavior of Dermacentor variabilis, Amblyomma americanum, and Ixodes scapularis in an in vitro vertical climb assay

    Repellents serve an important role in bite protection. Tick repellents largely rely on biomechanisms that induce responses with direct contact, but synthetic pyrethroids used as spatial repellents against insects have received recent attention for potential use in tick protection systems. An in vitro vertical climb assay was designed to assess spatial repellency against Dermacentor variabilis, Amblyomma americanum, and Ixodes scapularis adult, female ticks. Climbing behavior was assessed with and without the presence of two spatial repellents, transfluthrin and metofluthrin. Repellency parameters were defined to simulate the natural questing behavior of ambushing ticks, including measures of detachment, pseudo-questing duration, climbing deterrence, and activity. Significant effects were observed within each parameter. D. variabilis showed the greatest general susceptibility to each repellent, followed by A. americanum, and I. scapularis. The most important and integrative measure of repellency was climbing deterrence–a measure of the spatial repellent’s ability to disrupt a tick’s natural propensity to climb. Transfluthrin deterred 75% of D. variabilis, 67% of A. americanum, and 50% of I. scapularis. Metofluthrin was slightly more effective, deterring 81% of D. variabilis, 73% of A. americanum, and 72% of I. scapularis. The present study poses a novel paradigm for repellency and reports a preliminary assessment of spatial repellent effect on tick behavior. Further research will assess spatial repellency in a more natural setting, scale exposure conditions, and incorporate host cues

    "En el siguiente proyecto se desarrolló una prueba de concepto sobre el diseño e implementación de un prototipo de interfaz lingual que asemeja las funciones de un mouse. El dispositivo, idealmente, debe ser accionado y utilizado únicamente con la boca, debido a que está dirigido a pacientes con parestesia, es decir, personas con lesiones nerviosas o mecánicas en las extremidades superiores. La idea del mismo surge debido a las limitaciones que poseen estos pacientes a la hora de utilizar dispositivos electrónicos que, hoy en día son de uso cotidiano en la sociedad, en este caso, específicamente la computadora o dispositivos móviles."Proyecto final Bioingeniería (grado) - Instituto Tecnológico de Buenos Aires, Buenos Aires, 202

    Methodology for energetic and economic evaluation for the geothermal heat exploitation in an industrial facility

    No full text
    This work aims to analyse the use of low enthalpy geothermal heat in Bahía Blanca by evaluating different alternatives when using it in a specific project. In Bahía Blanca, Argentina, several boreholes with geothermal water have been used for many years. Although there are ageing wells in this area, many of which are proof of the existing considerable geothermal potential, only a few are deemed heat sources. The first section introduces general concepts for the contextualisation of the document. Then, the second section details all the performed methodology and an explanation about the selection of the industrial case is given. Then, the industrial system and pipelines are presented, followed by a description of the mass and energy balances. Later, the heat pump calculous, economic evaluation and CO2 footprint analysis procedures are presented. Finally, the fourth section presents all the obtained results in graphics and tables, and at the end, the conclusions are assessed

    Non-pharmaceutical intervention to reduce COVID-19 impact in Argentina

    No full text
    "This work is focused on the multilevel control of the population confinement in the city of Buenos Aires and its surroundings due to the pandemic generated by the COVID-19 outbreak. The model used here is known as SEIRD and two objectives are sought: a time-varying identification of the infection rate and the inclusion of a controller. A control differential equation has been added to regulate the transitions between confinement and normal life, according to five different levels. The plasma treatment from recovered patients has also been considered in the control algorithm. Using the proposed strategy the ICU occupancy is reduced, and as a consequence, the number of deaths is also decreased.

    Development of an end-effector for an industrial robot for the automates integration of threaded inserts into a hybrid additive manufactoring process

    In this thesis, a novel approach to automatically install threaded inserts into additive manufactured parts is developed and validated. Such an approach is highly relevant in the context of process automation and production of function-integrated parts. Automated production in combination with additive manufacturing has the potential for resource and energy-efficient production. This is becoming an increasingly important factor during decision making, due to climate change. Furthermore, additive manufacturing can support the development of climate-friendly solutions across all fields of application, as it enables quickly adaptable designs and flexible production methods. In addition, new design approaches to produce function-integrated components are becoming available. Integrating mechanical and electrical functional components during manufacturing makes it possible to realise an efficient and cost-effective integration procedure. The Fused Filament Fabrication (FFF) process can be used for this purpose, as it allows easy automation and expandability compared to other additive processes, plus a wide variety of materials can be processed. Initial literature research on the state of the art shows, that currently no process has been described, that combines the FFF process with a subtractive process and conductive filament. The 4K-FFF unit, the subject of this thesis, offers a unique approach to the automated production of function-integrated components. The system consists of a multi-material FFF printer with a milling and handling module. Manufacturing inaccuracies resulting from the FFF process can be compensated by the milling module. An industrial robot on the handling module is used to add functional components to the process. This setup enables the fully automated production of function-integrated components. For fastening and contacting the function-integrated components, threaded inserts are used, which have to be installed manually due to a lack of a suitable alternative. Literature research shows that there are no methods for the automated installation of threaded inserts into individual components, which are common in FFF. This shortcoming is addressed in this thesis. A new end-effector for the industrial robot is developed, which can grip, heat and install threaded inserts into a component. In addition, a quick-change system is established. Both expansions further increase the degree of automation of the 4K-FFF unit. A parameter optimisation procedure is carried out to determine the ideal operating parameters for the new end-effector. The functionality of the development and the quick-change system is validated by the production of demonstrator components
