Electromyographic data are recorded while the hand of subjects is constricted to grasps a set of spheres with a small variation in diameter. Five muscles are monitored with noninvasive electrodes placed on the skin of volunteers while a set of grasp–hold–relax tasks are carried out randomly. A preprocess stage is performed to extract time domain features from the data, with the purpose of addressing both the course of dimensionality and the issues related to the nonstationary behavior of electromyographic signals. A pattern recognition module is used to classify the data and to assign the extracted features to categories corresponding to each sphere grasped. A tracking generator is proposed using artificial neural networks, which are trained to learn the dynamics of finger motions. The performance...

The main goal of the proposed robotic prototype is to deal with the current situation of pandemic contingency, where students and instructors cannot attend laboratory facilities in person. The robotic system has four main components: an electromechanical robot arm structure, a control system, a Wi-Fi communications module, and a human-machine interface. The IoT (Internet of Things) robot arm can be used to demonstrate important robotics topics such as direct and inverse kinematics, which are shown by programming simple and complex motions using the Denavit-Hartenberg (DH) methodology. The capabilities of the robotic system are empowered by IoT technology, which is demonstrated with an HMI interface deployed in a smartphone using wireless Wi-Fi communication through an ESP32 microcontroller. The arm's purpose is to be a low-cost and replicable robot that aids the comprehension of robotics design through project-based learning, from the theoretical aspects to the actual coding and construction of a prototype.

By taking control of the hydroponic system through the use of these novel techniques and methodology mentioned in this document, the complete system can be managed as a cyber-physical system that represents outstanding advantages: it reduces human presence for monitoring, control, maintenance, or assistance to incidents. Since it is being monitored remotely, it also provides a large amount of data for analytical purposes such as Artificial Intelligence algorithms, machine learning, deep learning, among others. It is well known that hydroponic systems are experiencing a great demand in recent decades, and this is mainly due to increasing world population, lack of freshwater, climate change, demand for food, etc. Smart hydroponics systems help solve the problem. The main purpose of this article is to give an overview of the benefits of upgrading from traditional agricultural and hydroponic systems to the cyber-physical hydroponic system. Therefore, a prototype has been implemented to demonstrate that the techniques used are feasible and cost-effective.

Hence, there is an urgent need to find new and innovative ways to reduce the likelihood of infection. One of the most common ways of catching the virus is by being in contact with droplets delivered by a sick person. The risk can be reduced by wearing a face mask as suggested by the World Health Organization (WHO), especially in closed environments such as classrooms, hospitals, and supermarkets. However, people hesitate to use a face mask leading to an increase in the risk of spreading the disease, moreover when the face mask is used, sometimes it is worn in the wrong way. In this work, an autonomic face mask detection system with deep learning and powered by the image tracking technique used for the augmented reality development is proposed as a mechanism to request the correct use of face masks to grant ...

Solar power tower technology is a good example of this type of system, which consists of several mobile mirrors, called heliostats, which reflect the sun's radiation to the same point, located on top of a tower at the center of heliostat field, for collection or transformation into another type of energy. The so-called Hermosillo's Solar Platform (Plataforma Solar de Hermosillo, PSH, in Spanish) is a facility constituted with several heliostats, its aim and scope is for research purposes. In this paper, the implementation of a wireless communication system based on intelligent nodes is proposed in order to allow the communication and control of the heliostats in PSH. Intelligent nodes transmit information from one point to another, and can perform other actions that allow them to adapt to the conditions and limitations of a field of heliostats, thus achieving e...

The integration of IoT with Fog and Cloud Computing can bring not only the computational requirements, but they also enable IoT services to be pervasive, cost-effective, and can be accessed from anywhere and at any time. In any IoT application, communications are crucial to deliver the required information, for instance to take actions during crisis events. However, IoT components such as Gateways, usually referred as IoT nodes, will introduce major security challenges as they contribute to increase the attack surface, preventing the IoT to deliver accurate information to final users. In this paper, we present a methodology to develop an Intrusion Detection System based on Anomaly Behavior Analysis to detect when an IoT network node is being compromised. Our preliminary experimental results show that our approach accurately detects known and unknown anomalies due to misuses or cyber-attacks, with high detection rate and low false alarms.

In this paper, we propose the use of IoT platforms to link those homes that are equipped with IoT capabilities, in order to increase security and prevent from a crime to a fire, and even monitor health status of a person. Using a microcontroller, it is possible to send information to a cloud server capable of sharing this information with other households connected to the platform, as well as allowing linking this data to one of the most used social networks in the world: Facebook. Linking smart homes with social network, allows to consult the status of sensors and IoT devices empowering citizen security against crime, violence and events that could put the integrity of people at risk both in their property and their health. The study is carried out for a particular region of Latin America, given its high rates of violence against citizens that have occurred in recent years.

In order to deal with the real time implementation, an algorithm to significantly reduce the error that emerges in the solar tracking requirements is presented. Heliostats are oriented to reflect solar beam to a central receiver located in top of a tower. The heliostat tracks the apparent sun position with determined periodicity. A digital controller perform the tasks of calculate the control action to drive the actuators. The real time implementation of the control action introduces numerical issues that deviates the solar ray of the desired position. Results show that the proposed control strategy is able to track the solar sun position. The controller is implemented in real time via LabVIEW computational environment and is applied in a solar tower plant facility.

The herein contribution resides in the development and computation of an H∞ controller with parallel distributed compensation (PDC) designed from a highly nonlinear system modelled via the Takagi–Sugeno (T-S) fuzzy approach. A fuzzy-H∞ controller is synthesized for an OHSLV T-S fuzzy model of a suspension with two magnetorheological (MR) dampers including actuators’ nonlinear dynamics. The realism of results has been improved by considering the MR damper’s behaviours (viscoplasticity, hysteresis, and saturation) and the handling of the phase angle of the sinusoidal disturbance, not included in other reported work. Time-domain tests remark transient time achievements, whereas precise performance criterion indices in the frequency domain are employed to assess the generated outcomes. The proposed solution complies with all p...

The device was firstly tested in a controlled environment and then in a public healthcare institution with COVID-19 confirmed cases. In the controlled environment several microorganisms (not including SARS-CoV-2) were disseminated, and markers were placed at different locations to verify the behavior under normal conditions and then under the influence of the device to compare the environmental load of microorganisms through the time. Similar approach was applied in the healthcare institution where the SARS-CoV-2 was firstly confirmed and then the device was placed. The results show that, in the controlled environment, the device effectively reduce the load of microorganisms up 98% in 1/6th of the time, while in the healthcare institution the viral load can be reduced in up to 80% in few minutes.
