This paper describes the process of designing, building, and evaluating an IoT (Internet of things) ecosystem for three wireless technologies LoRa, Wi-Fi, and BLE. The system has a gateway connected to the internet by LTE and interacts with three sensor nodes; each sensor node uses a different wireless technology. The hardware control device is a Raspberry Pi3, the IoT web platform is a component of Azure. The development provides a flexible, autonomous, heterogeneous, and scalable network for IoT ecosystems that can analyze the real-time of each technology in the ecosystem. For this work real-time means a latency that has a value between 101 ms (milliseconds) and 6012 ms. Performance evaluation results using latency tests and maximum data sending range for each technology shows that the maximum range is 318 meters, and the lowest average latency is 1033 ms in LoRa and LTE interoperability.

There is a high demand for optical fiber to enable smart grid communication, as well as the need to advance the telecommunications sector, mainly related to IoT and 5G. The technology used in Brazil, of optical cables with loose tubes, limits the development of new high-capacity connectivity technologies. High density optical cables composed of flexible ribbons already exist outside Brazil [1] [2] and are a solution that makes it possible to considerably increase the number of fibers in a network. This work presents the development of optical cables composed of flexible ribbons for installation in ducts or lashed aerial networks, with 288 optical fibers, which allow greater compactness of optical networks and reduction in installation times and costs and commissioning.

Cognition and upper motor skills are some of the most common areas in rehabilitation of various pathologies; cognitive recovery can be supported on various areas as inhibition and object recognition, while motor skills require repetitive exercises, these make them the perfect target to develop serious games for catching the attention of patients and make easier for them to complete different tasks. This paper will show a qualitative usability evaluation of a serious game, developed for rehabilitation of cognition and fine motor skills. The game was built according to State-of-the-art determined design patterns as color, border definition and sound feedback, meanwhile the dynamics were chosen to match cognitive inhibition and object recognition recovery, implementing repetitive grasp and release tasks to enhanced motor abilities. At the end a usability study, based on Likert scale to estimate user’s opinion was carried out through a survey and applied to 21 physiotherapy and medicine students; concluding a good grade of usability, usefulness, playability and applicability of the application.

Hand Gesture and Sign Language Recognition are recognized as non-trivial problems in the computer vision community. Deep Learning (DL) has provided both, a novel analytical framework and solutions. Moreover, Convolutional Neural Networks (CNN) have shown there are still goals to be met and solutions to be given regarding Hand Posture Recognition with the architectures and technologies we have today. This work proposes building a Hand Gesture Recognizer able to identify 13 classes: numbers from 0 to 9, and the signs corresponding to the arithmetic operations of addition, subtraction, and multiplication. The core model aims to translate digits and math symbols signed by students and teachers in a school environment to both make the teaching-learning process more engaging and to promote sign language learning in the student community. Based on Object Detection and leveraging a pretrained model using Transfer Learning, this DL model was retrained with a data set of 1,365 images (105 per class/sign) of Panamanian Sign Language hand-shapes. An accuracy of 88% was reached on the validation data, with proved usefulness on American Sign Language (ASL) for these hand-shapes, and being easily adaptable to other sign systems, including two-handed finger spelling ones like International Sign System (IS).

Order preparation is a process of great impact in warehouses, this is because organizations always seek to provide a quality service, which today goes hand in hand with a fast delivery. Therefore, the objective of this article is to develop a mobile app that has the ability to read barcodes to complete purchase orders, and simultaneously generate a receipt that helps speed up the process. Its operation is simple and full of visual aspects that allow a practical handling of the app. The methodology was established by virtue of an experiment in which it is sought to affirm that the designed application helps to improve the order preparation time. As a result of the study that was carried out, it was possible to define that the implementation of the method supported by the application confirms that its contributions provide great benefits, its level of precision is not affected by the application and its investment costs vary only by 42% compared to traditional picking method. In conclusion, it is possible to interpret that the level of precision when using the application was 2.4 times more efficient than the traditional process.

It is neither practical nor economical to make continuous and direct measurements of the water flow in a stream, so indirect methods must be used to measure the water level and, based on a calibration curve, relate it to the corresponding flow rate. A hydraulic weir with a limnimeter fulfills this purpose, but its disadvantage is that it does not allow the automated registration of the water level and therefore new and more efficient technologies must be used to perform this measurement automatically and thus have a lower waste and optimization of the resource. This experiment develops an algorithm based on computer vision and the inclusion of the concepts of the Internet of Things, in order to measure and record the values of the water level in a hydraulic dam, also includes energy storage system, power supply, remote computer, devices with wireless communication and IoT platform that allow a measurement error of less than ± 2% to be obtained with respect to a visual measurement made by the operator.

The security of data exchange between IoT components is of vital importance to avoid integrity breaches in M2M relationships.The main reason for incorporating complex encryption strategies is the processing and memory limitations of embedded systems. This paper proposes an efficient alternative for encrypting messages between two IoT components with processes that make use of keys that change with each new communication making it difficult for brute force attacks to gain access to the exchanged content. Additionally, the method adds a mutation of the encryption functions that adds another additional difficulty to decrypt the message since it depends not only on the key but also on the sequence of application of the decryption functions. The algorithm can be scaled up to end nodes with larger resources, so that the number of bits of the keys and the complexity of the encryption functions can be further increased, and since it is applied directly on the payload, it is independent of any other security method used in higher layers.

To implement a Wireless Sensor Network to capture atmospheric data, the sensor nodes tend to be deployed in hard-to-reach areas, either to avoid abuse due to human interaction or as a result of the fact that variations in that zone are ideal to many studies. However, enter such areas or deploy a traditional Wireless Sensor Network can be difficult or expensive. Therefore, this research proposes to implement a data collection system of Wireless Sensor Network deployed in hard-to-reach areas or where the distance between sensors nodes does not allow the implementation of a network with mesh topology, using Unmanned Aerial Vehicle as mobile sink node, which collects data using Wi-Fi technology and HTTP protocol. To achieve this, a selection process of components and wireless communication technology was developed, which would integrate the system. Likewise, measurements were made that allowed determine the maximum separation distance at which the connection between sensor node and the sink node is guaranteed. In addition, the algorithms of components system were developed and implemented, and the system operation was evaluated through unit and integral tests. Among the results are the sensors network prototypes, maximum separation distance between nodes that gave as a result 35 meters, the algorithms for nodes firmware; and the coupling part design and 3D printing to the Unmanned Aerial Vehicle. In the same way, it was possible to verify the use of an Unmanned Aerial Vehicle as sink node for Wireless Sensor Network information collection implemented in the proposed scenarios is technically feasible.

This paper documents the consequences that occur in the absence of a diagnosis in Medium Voltage networks and cables in renewable energy applications (wind, photovoltaic), the lack or “savings” in prevention can lead to large economic losses and great disappointment in network users. In a scenario of digitalization, decarbonization and decentralization, the reliability and security of energy systems require prevention and diagnosis tools that allow achieving greater performance in the face of current challenges. Losses in power generation and losses due to repairs (corrective maintenance) are enormous and could directly and constantly affect the continuity of electrical systems.
