Modeling solar cavity receivers: a review and comparison of natural convection heat loss correlations
(Elsevier, 2015)
info:eu-repo/semantics/conferenceObject,
As the main difficulty of modeling cavity receivers is determining natural convection heat losses, this paper presents a survey of the different natural convection correlations developed by several authors to model natural ...
On the limits of the capacitor-voltage active damping for grid-connected power converters with LCL filter
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Active damping strategies are widely extended to avoid stability issues at the LCL filter resonant poles in grid-connected voltage source converters. The capacitor voltage derivative active damping effectively damps the ...
The promising combination of thermoelectric generators with IoT technologies for autonomous monitoring systems
(2019)
info:eu-repo/semantics/conferenceObject,
Monitoring stations becomes essential in any volcanic system in the world but, because of their remote location, both the electricity supply and the communications represent a technological challenge. The present work ...
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 ...
Advanced feeds for mm-wave antenna systems
(Springer, 2018)
info:eu-repo/semantics/bookPart,
Millimeter-wave antenna systems have traditionally required high performance feeds in order to fulfill its stringent requirements. Therefore, this goal has been achieved by corrugated horns. However, in the last years new ...
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 ...
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. ...
U2Eyes: a binocular dataset for eye tracking and gaze estimation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
Theory shows that huge amount of labelled data are needed in order to achieve reliable classification/regression methods when using deep/machine learning techniques. However, in the eye tracking field, manual annotation ...
A survey on detection techniques for cryptographic ransomware
(IEEE, 2019)
info:eu-repo/semantics/article,
Crypto-ransomware is a type of malware that encrypts user files, deletes the original data, and asks for a ransom to recover the hijacked documents. It is a cyber threat that targets both companies and residential users, ...
Effects of the body wearable sensor position on the UWB localization accuracy
(MDPI, 2019)
info:eu-repo/semantics/article,
Over the years, several Ultrawideband (UWB) localization systems have been proposed and evaluated for accurate estimation of the position for pedestrians. However, most of them are evaluated for a particular wearable sensor ...
