Advances in medical technology suggest that the application of implantable medical devices or Smart Hospital Devices (SHD) can enhance the control and treatment of chronic disorders. However, most of these developments require an electrical power source for operation, making the use of batteries unfeasible. This paper presents the design and resonance analysis of four different geometries for the fabrication of planar antennas as an alternative to a contactless power supply. Previously published software (Santiago-Amaya, López-García, Aguilar-Guggembuhl, Sánchez-Díaz, 2022) was used to calculate the electrical parameters for each coil design. Operating trials were executed under laboratory conditions, and a bracket manufactured using polylactic acid (PLA) through a 3D printer was used to accurately define the distances between coils to achieve correct alignment between them. Based on the experimental results, it was possible to calculate the resonant frequency of the inductive links at a 5 mm spacing. Similarly, it is possible to calculate the capacitive effect necessary to improve the resonant circuit in different transmitter-receiver planar antenna pairs. The most efficient combination to induce voltage in these links is to use the hexagonal profile design as a transmitter and receiver antenna, applying a sinusoidal signal with 8 MHz frequency.

This article aims to present a new problem of planning of resources and activities related to soccer, which is a variant of the Project Scheduling Problem. Soccer projects are intended to meet the requirements and expectations of time, cost and quality of the processes of the Soccer-related activities. In this article, original and unique in the world to date, is presented the mathematical modelling based on the Project Scheduling Problem of soccer in order to make optimal use of the resources of time, money and human resources of enterprises that you take care to engage in Soccer. The CPLEX model was used to find the optimal use of resources of the Soccer Project Scheduling Problem. [ABSTRACT FROM AUTHOR]

This paper presents a comprehensive state-of-the-art analysis and mathematical modeling of the National Program for Smart Cities (PRONACES) initiatives in Mexico's journey towards smart city development. The focus is on examining how PRONACES integrates technological innovation with urban planning and sustainability, leveraging mathematical models to optimize and predict the outcomes of various smart city initiatives. The methodology includes a review of current literature to establish the state of the art, followed by the development and application of mathematical models to assess and forecast the effectiveness of PRONACES strategies. These models are based on a variety of parameters including urban growth, technology adoption, resource allocation, and environmental impact. Key findings demonstrate the significant role of PRONACES in transforming urban landscapes in Mexico. The mathematical models provide valuable predictions and insights into the potential outcomes of various smart city strategies, indicating pathways for efficient resource management, infrastructure development, and sustainable urban growth. The paper concludes with an emphasis on the importance of mathematical modeling in planning and implementing smart city initiatives. The challenges and opportunities presented by Mexico’s unique urban landscape are discussed, along with recommendations for future research and policy-making in the field of smart urban development.

The technological progress that has been achieved today, has a tendency in the application of automated mechanisms to improve the life of the human being. In the area of communications there are great advances in different applications such as, for example, being able to monitor from a mobile device event that are happening remotely at a remote point, or, for example, to monitor the mechanized control of taking medication to patients in a hospital. The objective of this research work is to be able to establish communication with mobile devices to execute instructions issued by an intelligent logic system. This system is built by means of a bio-inspired algorithm ACO (Ant Colony Optimization) that has the purpose of generating logical information and three differential type LBOOT mobile devices.

Smart Education is the influence of diverse technologies (Combinatorial Optimization, Machine Learning, Big Data, data visualisation, Internet of Education Things, Learning analytics, and others) to enhance the quality of education. In other words, Smart Education is the process of optimally managing human, economic and technological resources from educational institutions and research centres. Smart Education is part of the Smart Society (a component of a Smart City). The Smart Education components are the Internet of Education Things (Wireless Sensor Networks, RFID Technology), management of the education physical, infrastructure, smart classroom, smart campus, smart learning, Learning analytics, Smart Analysis, data science, Education Impact, and Educational Policy. This paper is a guide for understanding Smart Education components by presenting a survey of the characteristics, taxonomy (Education-Hard problems and Education-Soft problems), smart education indicators, history and future trends.

Today, the entire environment that shapes our society is being modernized. Advances in technology allow us to materialize ideas that previously seemed impossible, from controlling a house to digitizing entire cities. This article proposes the design of an embedded system using V2X (Vehicle to Everything) communication. This electronic system is connected to smart devices to optimize vehicle flow in high conglomeration cities. This system communicates through IIoT (Internet of Industrial Things), allowing real-time information reception, in order to make decisions. This work is directed towards the alternative of intelligent cities, industry 4.0, and artificial intelligence techniques to improve the quality of life of people inhabiting a certain zone.

The measurement of liquid fuel in automotive vehicles, is critical to prevent malfunctions or mayor failures, predict travel autonomy, ignition engine efficiency and fuel economy. In this paper we introduce a novel system to measure the level of fuel in automotive tanks. The design of a sensor for measuring the volume of fuel level based on infra-red light emitter-receiver is illustrated. The dynamics volume on fuel in cars tank, can be represented with the variation of the height level in the tank and the surface, of due to the design with mechanical tannks asymmetry of the tanks. Other trouble is the response of the transducer, normally it has non linear operations i.e., dead zone, saturation, hysteresis; among others. In order to improve the approximation fuel volume to be measured, the fuzzy modelling Takagi-Sugeno (T-S) methodology was applied to the analogical signal obtained from the hardware that compose the sensor. In order to obtain reliable data from the transducer, a closed-loop control system to characterize and calibrate the sensor of fuel flow was implemented. The calibration of fuel volume sensor contained in the tank, was also validated with laboratory flasks and a cross validation with an electronic feedback control. A model with three fuzzy sets having cubic equations as consequent, has a highest precision than by using linear consequents. For the case of study, the RMS error of the fuzzy sensor was 128 mL in a tank of 7500 mL (1.7 %). •.The system to measure the fuel level in automotive tanks was currently carried out with primary element based in Ohm's law. • The modelling sensor proposed, prevents the fuel contact with the atmosphere, avoiding measurement errors. • The methodology proposed for sensor calibration was automated with a closed-loop to improve the measurement confidence. • A fuzzy identification is proposed to characterize the non linear sensor, by using human expertise and interpolation tools.
