Methodology to assess phasor measurement unit in the estimation of dynamic line rating
(Institution of Engineering and Technology, 2018-09)
This paper presents a methodology to analyse the influence of both atmospheric variations in time and space and the error in synchrophasor measurements to estimate conductor temperature along an overhead line. In this ...
Self-consistent solutions for line-driven winds of hot massive stars: The m-CAK procedure
(IOP Publishing, 2019-03)
Massive stars present strong stellar winds that are described by the radiation driven wind theory. Accurate mass-loss rates are necessary to properly describe the stellar evolution across the Hertzsprung-Russel Diagram. ...
Stairway Detection Based on Single Camera by Motion Stereo
(2011-06-28)
In this paper we are proposing a method for detecting the localization of indoor stairways. This is a fundamental step for the implementation of autonomous stair climbing navigation and passive alarm systems intended for ...
Open clusters: I. Fundamental parameters of B stars in NGC 3766 and NGC 4755
(EDP Sciences, 2012-08)
Context. Spectroscopic investigations of galactic open clusters are scarce and limited to a reduced sample of cluster members. Aims. We intend to perform a complete study of the physical parameters of two galactic clusters ...
Influence of stocking density on production and water quality of a photo-heterotrophic intensive system of white shrimp (Penaeus vannamei) in circular lined grow-out ponds, with minimal water replacementInfluence of stocking density on production and water quality of a photo-heterotrophic intensive system of white shrimp (Penaeus vannamei) in circular lined grow-out ponds, with minimal water replacement

Searching for line active molecules on biphasic lipid monolayers
(Royal Society of Chemistry, 2015-01)
In membranes with phase coexistence, line tension appears as an important parameter for the determination of the amount of domains, as well as their size and their shape, thus defining the membrane texture. Different ...
Control Strategy of True Time Delay Lines
(Taylor & Francis, 2017-03)
This article presents the control of adjustable true time delays applied to an optical beamforming system. First is introduced the response of ring resonators of two and four ports and the cascade and lattice structures. ...
Be and Bn stars: Balmer discontinuity and stellar-class relationship.
(EDP Sciences, 2020-02)
A significant number of Be stars show a second Balmer discontinuity (sBD) attributed to an extended circumstellar envelope (CE). The fast rotational velocity of Be stars undoubtedly plays a significant role in the formation ...
Open clusters: III. Fundamental parameters of B stars in NGC 6087, NGC 6250, NGC 6383 and NGC 6530. B type stars with circumstellar envelopes.
(EDP Sciences, 2018-02)
Context. Stellar physical properties of star clusters are poorly known and the cluster parameters are often quite uncertain.Aims. Our goals are to perform a spectrophotometric study of the B star population in open clusters ...
