    Optimal PID Control of a Brushed DC Motor with an Embedded Low-Cost Magnetic Quadrature Encoder for Improved Step Overshoot and Undershoot Responses in a Mobile Robot Application, Sensors 2022, 22(20), 7817.

    This paper describes the optimization of the PID control of a brushed DC motor (BDCM) with an embedded low-cost magnetic quadrature encoder. This paper demonstrates empirically that the feedback provided by low-cost magnetic encoders produces some inaccuracies and control artifacts that are not usually considered in simulations, proposing a practical optimization approach in order to improve the step overshoot and undershoot controller response.

    Paper published in the Special Issue: Practical Application of Sensors and Signal Processing Techniques in Mobile Robots

    This paper presents the enhancement of the sense of attention from the face of a human-sized mobile robot during an interaction. The perception of eye-gaze contact has been improved by manually calibrating the gaze of the robot relative to the location of the face of the person interacting with the robot. The sense of attention has been further enhanced by implementing cyclic face explorations with saccades in the gaze and by performing blinking and small movements of the mouth.

    This paper proposes a general procedure to evaluate and correct the systematic odometry errors of a human-sized three-wheeled omnidirectional mobile robot designed as a versatile personal assistant tool. The correction procedure is based on the definition of 36 individual calibration trajectories which together depict a characteristic flower-shaped figure.

    Classification of Two Volatiles Using an eNose Composed by an Array of 16 Single-Type Miniature Micro-Machined Metal-Oxide Gas Sensors, Sensors 2022, 22(3), 1120.
    Paper published in the Special Issue: Thin Film Gas Sensors

    This paper presents an electronic nose (eNose) composed by 16 identical BME680 MEMS sensors (using the miniature MOX gas sensor embedded in the BME680). This eNose has been applied to classify two volatiles.
    The main advantages of this eNose are: low-cost (less than 200 €), compact-size and low power (5.0 V & 0.9 W).

    Featured Scientific paper: Cross-reactive memory T cells associate with protection against SARS-CoV-2 infection in COVID-19 contacts, Nature Communications 13, 80 (Jan, 2022).
  • SARS-CoV-2 proteins contain heterologous and homologous epitopes predicted to cross-react with huCoVs.

  • 12/01/2021 - Entrevista con información COVID-19 y ventilación
    Entrevista a José Luis Jiménez, investigador de la Universidad de Colorado, El Español, enero 2022.
  • Negar que el virus se transmite por el aire es uno de los errores más graves en la historia de la salud pública.
  • ...las mascarillas... un filtro para que no salgan los virus al aire.
  • Primero, si se puede, ventilación. Si no se llega con la ventilación, entonces filtración, ya sea con filtros HEPA, si el edificio tiene instalación de filtros, o con filtros baratos con un ventilador.
  • Como decía Lord Kelvin, solo se puede mejorar lo que se mide. Teniendo medidores de CO2 que, por unos cien euros, te miden si estás ventilando bien o mal.
  • 07/01/2022 - Dispersion of cough-generated droplets
    Featured Scientific paper: Experimental study of the dispersion of cough-generated droplets from a person going up or downstairs, AIP Advances 12, 015002 (Jan, 2022).
  • The dispersion of cough-generated droplets from a person going up or downstairs was investigated through a laboratory experiment in a water tunnel.
  • Greater social distance is suggested for people going downstairs or riding descending escalators.
  • Proper and polite coughing posture is essential to prevent airborne transmission.
  • It is also critical that a person on an escalator cough or sneeze with the head down toward the ground so that the dispersed droplets (escaping from the blockage of the elbow or the tissue) are entrained into the wake region toward the ground. This may reduce the probability of droplets being inhaled by a person following behind.
