Worst expected ramp rates from cloud speed measurements
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
Large PV power ramp rates are of concern and sometimes even explicitly restricted by grid operators. Battery energy storage systems can smooth the power output and maintain ramp rates within permissible limits. To enable ...
Optical fiber vacuum sensor based on modal interferometer and PDMS coating
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
This work studies the behavior of polydimethylsiloxane (PDMS) as a transducer for optical vacuum pressure measurements. The optical structure chosen for this device is a modal interferometer achieved by splicing a coreless ...
Structural health monitoring of solar trackers using distributed fiber optic sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
We demonstrate the application of a novel type of distributed fiber optic sensors (DFOSs) to dynamically monitor the effects of wind on solar tracker structures used in photovoltaic power stations. This DFOS is based on ...
Directions of directional, ordered directional and strengthened ordered directional increasingness of linear and ordered linear fusion operators
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work we discuss the forms of monotonicity that have been recently introduced to relax the monotonicity condition in the definition of aggregation functions. We focus on directional, ordered directional and strengthened ...
High-speed analysis of SMB2 file sharing traffic without TCP stream reconstruction
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
This paper presents a file sharing traffic analysis methodology for Server Message Block (SMB), a common protocol in the corporate environment. The design is focused on improving the traffic analysis rate that can be ...
Energy harvesting approaches in IoT scenarios with very low ambient energy
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2019)
info:eu-repo/semantics/conferenceObject,
The feasibility of multi-source energy harvesting in Internet of Things (IoT) scenarios with low and intermittent ambient energy is addressed. As a relevant case study, application to a smart cargo container system is ...
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ...
Single feedback regulation of the AC voltage for high-power inverters under stand-alone operation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
Energy-storage inverters under stand-alone operation must control the output voltage. However, existing methods for instantaneous voltage regulation are not suitable for high-power inverters due to their limited sampling ...
Image, brand and price info: do they always matter the same?
(Association for Computing Machinery (ACM), 2019)
info:eu-repo/semantics/conferenceObject,
We study attention processes to brand, price and visual information about products in online retailing websites, simultaneously considering the effects of consumers’ goals, purchase category and consumers’ statements. We ...
Exploring the addition of audio input to wearable punch recognition
(Association for Computing Machinery (ACM), 2019)
info:eu-repo/semantics/conferenceObject,
Martial arts can promote healthy lifestyles, improve self-confidence and provide self-defence skills. Previous work has demonstrated that inertial sensors can be used to recognise movements such as punches in boxing and ...
