- 14th International Conference on Automatic Control and Soft-Computing CONTROLO’2020: book of abstractsPublication . Gonçalves, José (Ed.); Braz-César, Manuel (Ed.); Coelho, João Paulo (Ed.)On behalf of the Conference CONTROLO’2020 Committees, we welcome you to attend the 14th International Conference on Automatic Control and Soft Computing to be performed online, being organized from Bragança, Portugal, from 1 to 3 of July 2020. This conference edition will as plenary speakers a palette of five influential personalities in the automatic control systems design area. Their pioneer work has lay the foundations of the research ground that many of us is now following. Plenary Speakers: Prof. André J. Preumont: Emeritus Professor of Mechanical Engineering and Robotics and Director of the Active Structures Laboratory at the Université Libre of Bruxelles (Belgium). Author of several books on Vibration Control. Prof. Eduardo F. Camacho: Professor of Engineering of Systems and Automatics at Escuela Superior de Ingenieros in Sevilla (Spain). Author of several books on Model Predictive Control. Prof. Karl H. Johansson: Director of the Stockholm Strategic Research Area and Professor at the School of Electrical Engineering and Computer Science, KTH Royal Institute of Technology (Sweden). Prof. Kevin M. Passino: Professor of Electrical and Computer Engineering at the Ohio State University (USA). Author of several books on Biomimicry and Adaptive Control. Prof. Sebastián Dormido: Emeritus Professor at the Universidad Nacional de Educación a Distancia – UNED, ES. Former president of the Spanish Association of Automatic Control. The ideal situation would be to communicate face to face, but due to the current pandemic situation, we were forced to change the conference CONTROLO’2020 to an online event. From a practical perspective, the benefit of holding the online conference is that it allows attendees to avoid crowd contact and effectively prevent virus propagation. Nevertheless, we hope this will be a memorable, valuable, and enjoyable experience! We hope that all participants and other interested readers benefit scientifically from the proceedings and wish you success in your technical presentations and networking. Once again, thanks for your support to CONTROLO’2020 conference.

(Ed.); Morais, Pedro (Ed.); Pinto, Pedro (Ed.)SASYR, the rst Symposium of Applied Science for Young Researchers, welcomes works from young researchers (master students) covering any aspect of all the scienti c areas of the three research centres ADiT-lab (IPVC, Instituto Polit ecnico de Viana do Castelo), 2Ai (IPCA, Instituto Polit ecnico do C avado e do Ave) and CeDRI (IPB, Instituto Polit ecnico de Bragan ca). The main objective of SASYR is to provide a friendly and relaxed environment for young researchers to present their work, to discuss recent results and to develop new ideas. In this way, it will provide an opportunity to the ADiT-lab, 2Ai and CeDRI research communities to gather synergies and indicate possible paths for future joint work. We invite you to join us on 7 July and to share your research!

- A 2.4 GHz wireless electronic shirt for vital signals monitoringPublication . Carmo, João Paulo; Mendes, P.M.; Couto, Carlos; Correia, José H.The paper presents a wireless sensor network for wireless electronic shirts. This allows the monitoring of individual biomedical data, such as the cardio-respiratory function. The solution chosen to transmit the body’s measured signals for further processing was the use of a wireless link, working at the 2.4 GHz ISM band. A radio-frequency (RF) CMOS transceiver chip was designed in the UMC RF 0.18 μm CMOS process. The power supply of the RF CMOS transceiver is of only 1.5 V, thus it can be supplied by a single coin-sized battery. The receiver has a sensibility of -60 dBm and consumes 6.2 mW. The transmitter delivers an output power of 0 dBm with a power consumption of 15.6 mW. Innovative topics concerning efficient power management was taken into account during the design of the RF CMOS transceiver.

- A 2.4-GHz low-power/low-voltage wireless plug-and-play module for EEG applicationsPublication . Carmo, João Paulo; Dias, Nuno; Silva, Hélder; Mendes, P.M.; Couto, Carlos; Correia, José H.This paper presents a plug-and-play module for wireless electroencephalogram (EEG) applications. The wireless module is composed by an electrode, processing electronics, a radio-frequency (RF) transceiver, and an associated antenna. The RF transceiver was fabricated in the UMC RF 0.18 mum CMOS process, and operates in the 2.4-GHz ISM band. The receiver has a sensitivity of -60 dBm and a power consumption of 6.3 mW from a 1.8 V supply. The transmitter delivers an output power of 0 dBm with a power consumption of 11.2 mW, for a range of 10 m. It is also presented the electrical performance and comparison between different electrodes for EEG applications, namely sputtered titanium nitride (TiN) electrodes, standard sintered silver/silver chloride (Ag/AgCl) ring electrodes and sputtered iridium oxide (IrO2) electrodes. The experimental results show a better performance of the sputtered IrO2 electrodes compared with the standard sintered Ag/AgCl ring electrodes. These results promise a new opportunity for the application of a dry IrO2 electrodes in wireless modules for using in a wearable EEG braincap. These wireless EEG modules will allow patients to wear a brain cap and maintain their mobility, while simultaneously having their electrical brain activity monitored.
- A 2.4-GHz RF CMOS transceiver for wireless sensor applicationsPublication . Carmo, João Paulo; Mendes, P.M.; Couto, Carlos; Correia, José H.The paper describes a radio frequency transceiver designed in UMC RF 0.18 µm CMOS process. This process has a poly and six metal layers, allowing the use of integrated spiral inductors (with a reasonable quality factor), high resistor value (a special layer is available) and a low-power supply of 1.8 V. This RF CMOS transceiver will be applied to implemented a wireless sensors network in a wireless electronic shirt for helping health professionals with rapid, accurate and sophisticated diagnostic concerning cardiopulmonary disease in order to evaluate the presence of breathing disorders in free-living patients. Without proper design, communication will increase network power consumption significantly because listening and emitting are power-intensive activities. Thus, in order to optimise power consumption, it was included in the design of the RF transceiver, the use of control signals. With these control signals it is possible to enable and disable all the transceiver subsystems. These signals allows for example to switch off the receiver when a RF signal is being transmitted, to switch off the transmitter when a RF signal is being received, and to put the transceiver in sleeping mode when neither RF signals are being transmitted, nor being received.
- A 2.4-GHz wireless sensor network for smart electronic shirts integrationPublication . Carmo, João Paulo; Mendes, P.M.; Afonso, José A.; Couto, Carlos; Correia, José H.A typical sensing module is composed of sensors, interface electronics, a radio-frequency (RF) CMOS transceiver and an associated antenna. A 2.4-GHz RF transceiver chip was fabricated in a UMC 0.18 μm CMOS process. The receiver has a sensibility of -60 dBm and consumes 6.3 mW from a 1.8 V supply. The transmitter delivers an output power of 0 dBm with a power consumption of 11.2 mW. Innovative topics concerning efficient power management was taken into account during the design of the transceiver. A solution of individual sensing modules allows a plug-and-play solution. The target application is the integration of a wireless sensor network in smart electronic shirts, for monitoring the cardio-respiratory function and posture.

- 2D cloud template matching - a comparison between iterative closest point and perfect matchPublication . Sobreira, Héber; Rocha, Luís Freitas; Costa, Carlos M.; Lima, José; Costa, Paulo Gomes da; Moreira, António Paulo G. M.Self-localization of mobile robots in the environment is one of the most fundamental problems in the robotics field. It is a complex and challenging problem due to the high requirements of autonomous mobile vehicles, particularly with regard to algorithms accuracy, robustness and computational efficiency. In this paper we present the comparison of two of the most used map-matching algorithm, which are the Iterative Closest Point and the Perfect Match. This category of algorithms are normally applied in localization based on natural landmarks. They were compared using an extensive collection of metrics, such as accuracy, computational efficiency, convergence speed, maximum admissible initialization error and robustness to outliers in the robots sensors data. The test results were performed in both simulated and real world environments.
