Reconocimiento de expresiones faciales y características personales como herramienta para identificar personas en un sistema de transporte público

The use of artificial intelligence nowadays has many applications. This paper proposes the use of artificial intelligence based facial recognition using machine learning to identify through Python language, people who are missing, abducted or have committed crimes. The Jetson Nano development platform identifies and sends an alert via SMS text message to the monitoring and information control units for decision making and response. This device is based on the Ubuntu operating system, which can work standalone, is small, and allows easy accessibility in confined spaces. The tool can also predict people’s moods through gestures made on the face with the application of the Viola-Jones algorithm.La inteligencia artificial en la actualidad tiene muchas aplicaciones.

Ultraviolet concentration factor of a truncated compound parabolic concentrator under different weather conditions

This study presents the results of ultraviolet radiation measurement in a truncated compound parabolic concentrator. The measurements were performed by using of a portable ultraviolet sensor both inside and outside the concentrator without the presence of receiver, under direct and diffuse solar radiation, to calculate the real value of the concentration factor of ultraviolet radiation. The truncated compound parabolic concentrator was designed in Solid Works and built via 3D printing, with a theoretical concentration factor of 4.6. This study showed the differences in the form of the ultraviolet radiation when measurements were made under direct radiation and diffuse solar radiation. These differences are important when measurements were made along the concentrator profile, at different heights within the concentrator and, also, along it. Finally, a concentration factor of 3.3 and 1.4 were calculated on a sunny and a cloudy days, respectively. These values correspond to a concentration efficiency of 71.7 and 31.3%, respectively, against the theoretical value of 4.6 proposed in the design

Water treatment plant prototype with pH control modeled on fuzzy logic for removing arsenic using Fe(VI) and Fe(III)

This study proposes a fuzzy control strategy embedded in a Siemens IoT2040 gateway developed for removing inorganic arsenic from synthetic underground water in a treatment plant prototype. The prototype is used to dose a constant flow of Fe(VI) to maintain an oxide-reduction potential to guarantee the oxidation of arsenite into arsenate, while the fuzzy logic embedded in the IoT control manages the addition of Fe(III) to achieve a proper pH adjustment and efficient arsenate removal. The tests used synthetic Bangladesh groundwater enriched with 200 µg/L of arsenite and 200 µg/L of arsenate. The results revealed that the plant prototype yielded an effective treatment of the water. Arsenate was decreased to an average value of 6.66 µg/L and, the arsenite concentration decreased to 1.01 µg/L or less. These values were lower than the limit of 10 µg/L deemed by the World Health Organization as safe for human consumption.IDIC-Universidad de Lim

Development of a Fuzzy Logic-Based Solar Charge Controller for Charging Lead–Acid Batteries

The design and implementation of a solar charge controller for lead–acid batteries is intended to supplement a component of the water purification module of the water treatment unit for natural disaster relief. This unit contains a solar panel system that supplies power to the module by charging batteries through a controller comprising an Atmega 328 processor. The solar panel feeds voltage to the batteries through fuzzy logic-based software, which allows up to 6 A DC to pass through the controller’s power circuit. Consequently, the battery was charged in less time (an average of 7 h to reach maximum capacity), wherein battery lifespan is related to the charge wave frequency. Thus, our software may be adapted in different control algorithms without having to change hardware

Treatment of irrigation water infested with nematodes using a solar photoreactor

The objective of this study was to assess the efficacy of the disinfection of irrigation water loaded with the plant-parasitic nematode Meloidogyne incognita using a solar photoreactor. The photoreactor was comprised of a compound parabolic concentrator and a disinfection chamber made of boro-silicate glass where a static mixer coated or uncoated with TiO2 was installed. Water loaded with M. incognita was exposed to solar radiation within the reactor and recirculated while accumulated ultraviolet (UV) energy was registered. It was determined that an accumulated UV solar energy of 72 kJ/L inhibited the motility of juveniles while accumulated energy of 215 kJ/L was necessary to inhibit the egg hatching. Plants of lettuce irrigated with the treated water showed significantly less nodulation, higher air-dry weight and root dry-weight compared with the control group. No significant differences were found using the static mixer either coated with TiO2 or uncoated. © 2020 Desalination Publications

Todas estas áreas se combinan y formaran parte en este trabajo. Para lograr el objetivo planteado se empleará sensores de: altitud, velocidad, posición e inclinación angular. Se plantea también la utilización de un sistema de posicionamiento global (GPS), estas coordenadas obtenidas serán comparadas con una ruta de vuelo previamente establecida, la idea es poder replicar esta, con la que se generaría al momento del vuelo y tratar de aproximarla con una lógica de control basado fundamentalmente con las teorías de la lógica difusa, esto enmarcado dentro de un sistema computacional conocido como DSP.The objective of this thesis is to control aeromodel, through the application of Automatic Control techniques. It will be necessary to use the tools of Engineering in several of their fields, including the system analysis, the automatic control, and instrumentation as well as the electronic, mechanical and electronic design. All of these areas were involved in this project. To achieve the objective is to be used sensors for altitude, speed, position, forces G e inclination were used especially designed for measurement and control mechanisms based on fuzzy logic. The final product consists of a low-cost pilot platform of, geared to development of advanced control strategies. It has been also used a global positioning system (GPS), the gps coordinates obtained were compared with a flight route previously established. The idea is to replicate this route as the set point to follow using a logic of control based primarily with the theories of fuzzy logic within a computer system known as DSP. The behavior obtained with the strategies were carried out by flight simulation programs such as the “flight simulator™”. This project includes the flight of airplane with all the electronic described above, but do not include the maneuvers of takeoff and landing because it puts at risk not only the plane the project, in doing so these processes nullifies any activity on the DSP and takes the manual command through the radio control of the aeromodel.Tesi
