Fourier analysis of submillimeter-wave scattering from the human cornea
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessWave scattering from a human cornea illuminated with a submillimeter-wave Gaussian beam is explored with Fourier analysis. This new approach enabled us to investigate the cornea as a coated sphere rather than a homogenized ... -
Multilingual machine translation: Closing the gap between shared and language-specific encoder-decoders
(Association for Computational Linguistics, 2021)
Conference lecture
Open AccessState-of-the-art multilingual machine translation relies on a universal encoder-decoder, which requires retraining the entire system to add new languages. In this paper, we propose an alternative approach that is based on ... -
Algorithm for resonator parameter extraction from symmetrical and asymmetrical transmission responses
(IEEE Microwave Theory and Techniques Society, 2021-06-07)
Article
Open AccessWe describe an algorithm capable of extracting the unloaded quality factor and the resonant frequency of microwave resonators from vector S-parameters. Both symmetrical (Lorentzian) and asymmetrical (Fano) transmission ... -
Estimation of information in parallel Gaussian channels via model order selection
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference lecture
Open AccessWe study the problem of estimating the overall mutual information in M independent parallel discrete-time memory-less Gaussian channels from N independent data sample pairs per channel (inputs and outputs). We focus on the ... -
Design and Testing of a Helix Antenna Deployment System for a 1U CubeSat
(Institute of Electrical and Electronics Engineers (IEEE), 2021-05)
Article
Open AccessCubeSats have revolutionized Earth Observation and space science, although their small size severely restricts satellite performance and payload. Antenna deployment from a stowed configuration in these small-satellites ... -
2D–3D geometric fusion network using multi-neighbourhood graph convolution for RGB-D indoor scene classification
(Elsevier, 2021-12)
Article
Restricted access - publisher's policyMulti-modal fusion has been proved to help enhance the performance of scene classification tasks. This paper presents a 2D-3D Fusion stage that combines 3D Geometric Features with 2D Texture Features obtained by 2D ... -
The TALP-UPC system for the WMT similar language task: statistical vs neural machine translation
(Association for Computational Linguistics, 2019)
Conference lecture
Open AccessAlthough the problem of similar language translation has been an area of research interest for many years, yet it is still far from being solved. In this paper, we study the performance of two popular approaches: statistical ... -
Machine-learning based traffic forecasting for resource management in C-RAN
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policyThe assumption of a fixed computational capacityat the Baseband Unit (BBU) pools in a Cloud Radio Access Network (C-RAN) deployment results in underutilized resourcesor unsatisfied users depending on ... -
Prediction of the optimal phase shift between control signals in dual-input power amplifiers
Conference report
Restricted access - publisher's policyThis paper evaluates the effect of the phase shift between the two control signals in a dual-input load modulated balanced amplifier (LMBA). While the drain efficiency of the LMBA is not significantly affected by the phase ... -
An UWB Tapered Slot Vivaldi Antenna (TSA) with improved characterestics
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyIn this paper, an UWB Tapered Slot Vivaldi Antenna (TSA) is presented. The proposed TSA is optimized in order to increase the bandwidth and ensure a good impedance matching at low and bandwidth frequencies while respecting ... -
Refinement of unsupervised cross-lingual word embeddings
(Ios Press, 2020)
Conference lecture
Open AccessCross-lingual word embeddings aim to bridge the gap between high-resource and low-resource languages by allowing to learn multilingual word representations even without using any direct bilingual signal. The lion's share ... -
The flexible microwave payload -2: design, implementation, and optimization of a GNSS-R and radiometry processor for cubesat-based earth observation missions
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThe Flexible Microwave Payload 2 (FMPL-2) is a Remote Sensing payload carried on board 3 Cat-5/A, one of the two 6-unit CubeSats of the FSSCat mission. FMPL-2 is a payload based on a Software Defined Radio (SDR), integrating ...
