Algorithms for determining relative position between spheroids and hyperboloids with one sheet
(Elsevier, 2019-06)[Abstract]: In this work we present a new method for determining relative positions between one moving object, modelled by a bounding spheroid, and surrounding static objects, modelled by circular hyperboloids of one sheet. ... -
Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI
(Institute of Electrical and Electronics Engineers, 2023-11-28)[Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ... -
Alternatives for Locating People Using Cameras and Embedded AI Accelerators: A Practical Approach
(MDPI, 2021)[Abstract] Indoor positioning systems usually rely on RF-based devices that should be carried by the targets, which is non-viable in certain use cases. Recent advances in AI have increased the reliability of person detection ... -
An Electricity Price-Aware Open-Source Smart Socket for the Internet of Energy
(M D P I AG, 2017-03-21)[Abstracts] The Internet of Energy (IoE) represents a novel paradigm where electrical power systems work cooperatively with smart devices to increase the visibility of energy consumption and create safer, cleaner and ... -
An Experimental Set-Up for Measurement of the Power Absorbed from 900 MHz GSM Standing Waves by Small Animals, Illustrated by Application to Picrotoxin-Treated Rats
(Electromagnetics Academy, 2008)[Abstract] We describe an experimental set-up for exposure of small animals to radiofrequency standing waves that allows direct measurement of the power absorbed by the animal. Essentially, the set-up consists of a metallic ... -
An IoT and Blockchain Based System for Monitoring and Tracking Real-Time Occupancy for COVID-19 Public Safety
(MDPI, 2020-11-14)[Abstract]: The COVID-19 pandemic has brought several limitations regarding physical distancing in order to reduce the interactions among large groups that could have prolonged close contact. For health reasons, such ... -

An overview of IoT architectures, technologies, and existing open-source projects
(Elsevier, 2022-11)[Abstract]: Today’s needs for monitoring and control of different devices in organizations require an Internet of Things (IoT) platform that can integrate heterogeneous elements provided by multiple vendors and using ... -
Analog Beamforming Using Time-Modulated Arrays With Digitally Preprocessed Rectangular Sequences
(Institute of Electrical and Electronics Engineers, 2018-03)[Abstract]: Conventional time-modulated arrays are based on the application of variable-width periodical rectangular pulses (easily implemented with radio frequency switches) to the individual antenna excitations. However, ... -
Analog joint source-channel coding over MIMO channels
(SpringerOpen & European Association for Signal Processing, 2014-02)[Abstract]: Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost ... -
Analog Transmission of Correlated Sources Over BC With Distortion Balancing
