KISS methodologies for network management and anomaly detection
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Current networks are increasingly growing in size, complexity and the amount of monitoring data that they produce, which requires complex data analysis pipelines to handle data collection, centralization and analysis tasks. ...
Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A metasurface based decoupling structure that is composed of a square-wave slot pattern with exaggerated corners that is implemented on a rectangular microstrip provides high-isolation between adjacent patch antennas for ...
Mutual-coupling reduction in metamaterial substrate integrated waveguide slotted antenna arrays using metal fence isolators for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A new type of mutual coupling reduction technique is applied to metamaterial substrate integrated waveguide (SIW) slotted antenna array. The circular shaped reference SIW antenna array is constructed from Alumina substrate ...
A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper a novel technique is proposed to reduce the mutual coupling between the radiating elements of a waveguide slot array antenna. This is achieved by inserting slots between the waveguide oval shaped slots. The ...
Dual-mode soft-transition control for single-phase grid-connected photovoltaic inverters
(IEEE, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
Single-phase grid-connected inverters for photovoltaic power generation have been strongly analysed for improvement. Dual-mode control for two-stage inverters makes it possible to improve the efficiency by alternating ...
Improved strategies for HPE employing learning-by-synthesis approaches
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
The first contribution of this paper is the presentation of a synthetic video database where the groundtruth of 2D facial landmarks and 3D head poses is available to be used for training and evaluating Head Pose Estimation ...
Supervised descent method (SDM) applied to accurate pupil detection in off-the-shelf eye tracking systems
(ACM, 2018)
info:eu-repo/semantics/conferenceObject,
The precise detection of pupil/iris center is key to estimate gaze accurately. This fact becomes specially challenging in low cost frameworks in which the algorithms employed for high performance systems fail. In the last ...
Techno-economic assessment of high renewable energy source penetration in the Bolivian interconnected electric system
(University of Minho, 2018)
info:eu-repo/semantics/conferenceObject,
To reduce GHG emissions to reach the 2°C level, the International Energy Agency, projected that electricity generation based in renewable source should increase from 3% today to more than 20% by 2040 [1]. This transition ...
Folded Cascode OTA with 5540 MHzpF/mA FoM
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced ...
On the optimal current followers for wide-swing current-efficient amplifiers
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to ...
