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 ...
Fuzzy logic-based energy management system design for residential grid-connected microgrids
(IEEE, 2018)
info:eu-repo/semantics/article,
This paper presents the design of a low complexity fuzzy logic controller of only 25-rules to be embedded in an energy management system for a residential grid-connected microgrid including renewable energy sources and ...
Sliding window averaging in normal and pathological motor unit action potential trains
(Elsevier, 2018)
info:eu-repo/semantics/article,
Objective: To evaluate the performance of a recently proposed motor unit action potential (MUAP) averaging method based on a sliding window, and compare it with relevant published methods in normal and
pathological muscles. ...
Meta-surface wall suppression of mutual coupling between microstrip patch antenna arrays for THz-band applications
(EMW Publishing, 2018)
info:eu-repo/semantics/article,
This paper presents a novel 2D meta-surface wall to increase the isolation between microstrip patch radiators in an antenna array that is operating in the teraherz (THz) band of 139-141 GHz for applications including ...
Diseño y desarrollo de estructuras ópticas para la fabricación de sensores de fibra óptica
(2018)
Tesis doctoral / Doktoretza tesia,
Actualmente existe una gran variedad de opciones para el sensado mediante métodos ópticos y, más concretamente, para el desarrollo de sensores utilizando fibra óptica. Aunque la mayoría de los principios físicos utilizados ...
On the on-site measurement of the degradation rate of crystalline silicon PV modules at plant level
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
This paper proposes a method for measuring the degradation rate of crystalline silicon PV modules at plant level in two different ways as a form of verification. As actual levels of degradation rate have been observed to ...
A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper, a new method is proposed to reduce mutual coupling between waveguide slot array (WSA) antennas based on metasurface technology. This is achieved by placing a metasurface bulkhead between the two WSA antennas. ...
Fast and robust ellipse detection algorithm for head-mounted eye tracking systems
(Springer, 2018)
info:eu-repo/semantics/article,
In head-mounted eye tracking systems, the correct detection of pupil position is a key factor in estimating gaze direction.
However, this is a challenging issue when the videos are recorded in real-world conditions, due ...
Introducing I2Head database
(ACM (Association for Computing Machinery), 2018)
info:eu-repo/semantics/conferenceObject,
I2Head database has been created with the aim to become an optimal reference for low cost gaze estimation. It exhibits the following outstanding characteristics: it takes into account key aspects of low resolution eye ...
