Human-machine interfaces (HMIs) have received an increased attention during the past decades, specially due to the use of robots in many fields of the industry. In this paper, we employ a hand gesture recognition (HGR) system and the inertial measurement unit (IMU) integrated in the Myo Armband sensor as a HMI to control the position and orientation of a virtual six-degree-of-freedom (DoF) UR5 robot. As part of the HMI, this work also focuses on solving the trajectory tracking problem for the UR5 robot using two different control strategies: a minimum norm PID and a controller based on linear algebra. Both controllers are designed from the UR5 kinematic model. Finally, we test and compare their performance by computing their IAE performance criterion and the position errors obtained from two experiments: tracking pre-defined input trajectories and commanding the virtual robot by the HGR system plus the Myo Armband's IMU signals.

Systems used for pattern recognition are usually divided into 4 stages: signal acquisition, preprocessing, feature extraction and classification. However, the use of algorithms in these last 3 stages is not justified and researchers use them without criteria other than the result achieved at the end of the process. In this paper we propose a new methodology and show its particular application to the recognition of five hand gestures based on 8 channels of Electromyography using the Myo armband device placed on the forearm. If n features are extracted, they will form clusters of points in n-dimensional space and now the selection of the best preprocessing algorithms and the best features are based on maximizing the distance among clusters. On the other hand, both intrapersonal and interpersonal variability are treated to facilitate the understanding of the phenomenon. As a demonstration, it was applied to 12 people and the recognition accuracy was 97%.

This work reports a control platform development for a low-cost and portable medical imaging breast cancer detection system. Firmware was developed from scratch contemplating the hardware control, automated internal sweeping routines, and attending personal computer queries via USB communication. Custom commands were implemented for the external communication employing a simple and effective ASCII protocol. The platform allows both hardware technician and exam operator to interact with the hardware from register level to elaborated routines, enabling advanced intervention as well as automatic and fast measurement tasks. Results reported calibration and sweeping times reduced from minutes to less than 2.5 seconds per examination step. A complete 64 positions exam time is estimated in 28 minutes and currently depends primarily on the mechanical equipment setup.

The arrival of the covid-19 pandemic has generated a turning point in the way people live. A maj or role for telecommunications technology has been playing in enabling interaction between people and the productivity of people within an organization, despite restrictions put in place by several governments because of the pandemic. The massive use of ICT also exposes users and organizations to be victims of a possible cyber-attack. This paper aims to review the impact of the covid-19 pandemic on cybersecurity in Latin America, which have been the most recurrent attacks and some reported cases. For this purpose, we examined a literature review on the different types of cyberattacks, reports provided by multiple organizations in the field of cybersecurity, and news from Latin American countries about cybercrimes related to the covid-19 pandemic. It also discusses a trend in cyberattacks and some recommendations to improve cybersecurity for individuals and organizations. It concludes by defending the need to have a culture of cybersecurity to minimize the impact of cyber-attacks at both the organizational and individual levels.

Internet, mobile networks, and mobile devices have contributed to the massive development of telematics applications. Therefore, the underlying communication network that supports the connectivity of these applications must provide an adequate level of QoS. On the other hand, the advent of new networking paradigms such as Software Defined Networks (SDN) has transformed the telco landscape. Consequently, traditional teletraffic engineering techniques cannot comply with the requirements of agile, dynamic, and tailored traffic controls. In this context, a proposal to improve the QoS of communication networks by optimizing the path planning process using the machine learning principles is presented. Thus, path planning is considered a multi-classification problem. Several configurations of three machine learning classifiers have been evaluated to determine the best model. Two class-balanced experimental datasets named Dl and D2 were created for validation purposes. The support vector machine classifier with a linear kernel and cost c = 102 was the best model obtaining a mean of an area under the receiver operating characteristics curve of 0.999 using the D1 dataset. The same classifier with a polynomial kernel and cost c = 10 achieved a score of 0.999 using the D2 dataset. These results statistically overcame the remaining classification schemes at $a$ = 0.05, determining the support vector machine model as the best classifier to find optimal paths between endpoints.

In Ecuador, shrimp exports have gained importance in recent years such that it represents a strong income in the country's economy. However, some shrimp farms do not have the appropriate technology to carry out controlled and efficient automated farming. Fuzzy logic is an efficient and effective way to establish rules of behavior of a system for solving an industrial problem. This paper explores the implementation of a monitoring and control system in shrimp farming, to obtain better growth results by using a qualitative model of intelligent supervision. Finally, to evaluate this model based on linguistic rules, we analyzed the open-loop and closed-loop response

Motor disability is the loss of the ability to move a limb of the body. Motor disabilities make difficult the interaction between a disabled person and her/his environment. Recent research has focused on developing innovative technologies that could be used by disabled people to improve their life quality. In this paper, a brain-computer interface for controlling IoT devices is proposed. This system is based on the use of the Muse-Headband sensor which captures EEG signals when a person blinks. This sensor is placed on the forehead of the user of the system. The EEGs are preprocessed and then classified into short and long blinks by computing their signal envelopes and using the k-NN algorithm. The classified blinks are then used to form control commands that are sent to a mosquitto server hosted in the cloud. This server is responsible for sending the control action to the connected IoT devices. The accuracy of the classifier designed in this work is 99.53%. Usability tests show that the probability of a user sending a wrong command, with the proposed system, is 4.83%. However, this probability decreases when the time of use of the system proposed in this work increases.

Fifth-generation (5G) wireless technologies are characterized by high-speed transmission and greater capacity for millions of devices interconnected with low latency. However, having various enabling technologies like Network Slicing introduces new threats. In this work, we propose to carry out a systematic review of the literature that studies Cybersecurity in this environment. The Kitchenham & Carters method is used, posing three research questions. As a result, 41 papers that met the semantic search criteria were analyzed in the Science Direct Elsevier database, IEEE eXplorer digital library, and ACM digital library. The main security issues that affect 5G Network Slicing technology and the possible solutions that mitigate the vulnerabilities found were identified.

This paper is about off line continuous time systems identification. In particular, it deals with the identification of the temperature and pressure processes dynamics of viscous fluids in an industrial plate heat exchanger (PHE) by estimating the parameters of the Multiple Input Multiple Output (MIMO) model. The lineal model is obtained around the linear dependence breaking point between the temperature and pressure variables of the glycerin and the viscosity of the working fluid. As a result of the identification, a multivariate model with two inputs and two outputs is provided which presents a fit of [87.79; 99.66] % (prediction focus), and FPE: 1.72e-07, MSE: 0.003592 with poles and zeros in the complex LHP plane suitable for control, what will allow to extend the investigation to the processes control with dynamics difficult to control. Keywords- MIMO systems identification, plate heat exchanger, transfer function matrix, poles and zeros, Gershgorin band

The GALS (Globally Asynchronous Locally Synchronous) paradigm is a promising alternative to implement SoC (Systems-on-Chip). GALS systems are formed by synchronous modules that operate with unrelated clock signals and interact with self-timed communication. An asynchronous wrapper is generated for each synchronous module, where a clock generator and communication ports (asynchronous channels) are inserted. Two criticisms of GALS systems based on the asynchronous wrapper are the cost of communication and metastability. In this paper, we propose a new asynchronous wrapper geared towards the GALS pipeline. Compared to asynchronous wrappers from the literature, it reduces communication cost and area reduction and is free of metastability. Our wrapper's main feature is a new controller port that performs the two-phase protocol's input/ output communication functions and generates the stretchable clock signal.
