Mission and system architecture for an operational network of earth observation satellite nodes
(2019)
Conference lecture
Restricted access - publisher's policyOver the next few years, Europe will take important steps towards implementing the architecture of the Copernicus Space Component for Earth Observation (EO), fulfilling the needs of stakeholders concerned with land monitoring, ... -
A novel formulation of independence detection based on the sample characteristic function
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Restricted access - publisher's policyA novel independence test for continuous random sequences is proposed in this paper. The test is based on seeking for coherence in a particular fixed-dimension feature space based on a uniform sampling of the sample ... -
Performance measurements-based estimation of radio resource requirements for slice admission control
(2019)
Conference report
Restricted access - publisher's policyThe network slicing capability introduced in 5G systems facilitates the realisation of flexible multi-tenant networks. Network slicing enables the partition of a common shared network in several logical networks, each ... -
Analytical modeling method of thermal spreading resistance in BAW filters
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyAs the power requirements in BAW filters steadily increase, thermal behaviour emerges as a key asset to ensure device performance and reliability. Under these conditions, self-heating mechanisms drive to possible situations ... -
Role of SiO2 layers in third-order nonlinear effects of temperature compensated BAW resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThis work applies a comprehensive nonlinear characterization process of two Temperature Compensated Bulk Acoustic Wave (TC-BAW) resonators. In both resonators, the SiO 2 layers have a remarkable impact on the generation ... -
N-Plexer and N-Band acoustic filters based on transversal configuration
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyThis work shows the feasibility of using filters with transversal configuration to create N-Plexers and N-Band responses, by directly connecting several BAW filters in a transversal manner. The new multi-filtering solutions ... -
Analysis of border ring modes on SMR-BAW resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyAn equivalent circuit model is proposed in order to model the Border Ring (BR) spurious modes on Type I Solidly Mounted Resonators (SMR) BAW resonators and the cancellation of the in-band lateral modes that the BR frame ... -
Squared-loss mutual information via high-dimension coherence matrix estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policySquared-loss mutual information (SMI) is a surro- gate of Shannon mutual information that is more advantageous for estimation. On the other hand, the coherence matrix of a pair of random vectors, a power-normalized version ... -
Study of interconnecting switch currents in reconfigurable parasitic layer antennas
(2019)
Conference lecture
Restricted access - publisher's policyThis work presents an approach for calculating the currents across the switches of a reconfigurable parasitic layer intended to add beam-steering capabilities to a reference antenna. The method of analysis is based on the ... -
Interference mitigation under degrees-of-freedom sensing uncertainties in opportunistic transmission
(2019)
Conference report
Restricted access - publisher's policyInter-system interference may limit the performance of co-existing systems in dense heterogeneous wireless networks. Context-aware waveform design can profitably overcome this limitation. However, the latter substantially ... -
From bilingual to multilingual neural machine translation by incremental training
(Association for Computational Linguistics, 2019)
Conference lecture
Open AccessMultilingual Neural Machine Translation approaches are based on the use of task specific models and the addition of one more language can only be done by retraining the whole system. In this work, we propose a new training ... -
VLX-Stories: building an online Event Knowledge Base with Emerging Entity detection
(Springer, 2019)
Conference lecture
Restricted access - publisher's policyWe present an online multilingual system for event detection and comprehension from media feeds. The system retrieves information from news sites, aggregates them into events (event detection), and summarizes them by ...
