Determination of pumping and dynamic vacuum properties of conductive quaternary alloy of TiZrVAg non-evaporable getter
Conference report
Open AccessNon Evaporable Getter (NEG) coating has been employed extensively in the particle accelerator especial-ly where the vacuum conductance of the vessel is se-verely restricted and ultra-high vacuum condition is required. NEG ... -
Data driven joint sensor fusion and regression based on geometric mean squared error
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference lecture
Open AccessThis paper explores the problem of estimating a temporal series measured from multiple independent sensors with unequal and stationary measurement errors with unknown variances. By formulating the data fusion problem as a ... -
Sign language translation from instructional videos
(Computer Vision Foundation, 2023)
Conference report
Open AccessThe advances in automatic sign language translation (SLT) to spoken languages have been mostly benchmarked with datasets of limited size and restricted domains. Our work advances the state of the art by providing the first ... -
Tackling low-resourced sign language translation: UPC at WMT-SLT 22
(Association for Computational Linguistics, 2022)
Conference lecture
Open AccessThis paper describes the system developed at the Universitat Politècnica de Catalunya for the Workshop on Machine Translation 2022 Sign Language Translation Task, in particular, for the sign-to-text direction. We use a ... -
MIMO radar antenna with sectorial human torso illumination for an in-cabin breathing detection system
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference report
Open AccessThe vital sign measurement systems inside vehicles have taken great or impulse in recent years, and the technologies that have been most welcomed are based on wireless measurements that do not interrupt driving and are ... -
Experimental measurements of radio signal attenuation and Faraday rotation in an inductively coupled plasma facility
(Karman Institute for Fluid Dynamics, 2023)
Conference report
Open AccessSpacecraft entering a planetary atmosphere are surrounded by a plasma layer containing high levels of ionization due to the high temperatures on the shock layer. The high electron number densities cause attenuation and ... -
Evaluating gender bias in speech translation
(European Language Resources Association, 2022)
Conference lecture
Open AccessThe scientific community is increasingly aware of the necessity to embrace pluralism and consistently represent major and minor social groups. Currently, there are no standard evaluation techniques for different types of ... -
Ionospheric scintillation anomalies associated with the 2021 La Palma volcanic eruption detected with Gnss-R and Gnss-Ro observations
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Restricted access - publisher's policyRecent studies have shown possible signatures or precursors of seismic activity in the ionosphere. Our group is focusing on ionospheric scintillation associated with seismic activity. By the time this study was conducted, ... -
Solving electromagnetic scattering in dielectric bodies by Monte Carlo sampling
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Restricted access - publisher's policyIn this work, we propose Monte Carlo sampling as a technique to avoid communication overhead in the numerical solution of complex electromagnetic scattering problems. The method is based on statistically sampling a ... -
A deep q network-based multi-connectivity algorithm for heterogeneous 4G/5G cellular systems
(Springer, 2022)
Conference report
Restricted access - publisher's policyMulti-connectivity, which allows a user equipment to be simultaneously connected to multiple cells from different radio access network nodes that can be from a single or multiple radio access technologies, has emerged as ... -
Slow-envelope shaping function FPGA implementation for 5G NR envelope tracking PA
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference lecture
Restricted access - publisher's policyThis paper focuses on the FPGA implementation of a slew-rate reduction (SR) shaping function for envelope tracking (ET) power amplifiers (PAs). The SR envelope has been proved effective to trade-off power efficiency and ... -
Alignment of terahertz transmission setups with free-space laser photoconductive switches
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference lecture
Restricted access - publisher's policyA systematic procedure for ensuring perfect alignment of Photoconductive Antennas (PCA) in transmittance measure setups with free-space laser PCA gap feeding and mechanical adjust of silicon substrate lenses is presented. ...
