Binary versus Multiclass Deep Learning Modelling in Energy Disaggregation

This paper compares two different deep-learning architectures for the use in energy disaggregation and Non-Intrusive Load Monitoring. Non-Intrusive Load Monitoring breaks down the aggregated energy consumption into individual appliance consumptions, thus detecting device operation. In detail, the “One versus All” approach, where one deep neural network per appliance is trained, and the “Multi-Output” approach, where the number of output nodes is equal to the number of appliances, are compared to each other. Evaluation is done on a state-of-the-art baseline system using standard performance measures and a set of publicly available datasets out of the REDD database.

TICs 167692429 and 220397947: the first compact hierarchical triple stars discovered with TESS

ABSTRACT We report the discovery and complex analyses of the first two compact hierarchical triple star systems discovered with TESS in or near its southern continuous viewing zone during Year 1. Both TICs 167692429 and 220397947 were previously unknown eclipsing binaries, and the presence of a third companion star was inferred from eclipse timing variations exhibiting signatures of strong third-body perturbations and, in the first system, also from eclipse depth variations. We carried out comprehensive analyses, including the simultaneous photodynamical modelling of TESS and archival ground-based WASP light curves, as well as eclipse timing variation curves. Also, for the first time, we included in the simultaneous fits multiple star spectral energy distribution data and theoretical PARSEC stellar isochrones, taking into account Gaia DR2 parallaxes and catalogued metallicities. We find that both systems have twin F-star binaries and a lower mass tertiary star. In the TIC 167692429 system, the inner binary is moderately inclined (imut = 27°) with respect to the outer orbit, and the binary versus outer (triple) orbital periods are 10.3 versus 331 d, respectively. The mutually inclined orbits cause a driven precession of the binary orbital plane that leads to the disappearance of binary eclipses for long intervals. In the case of TIC 220397947, the two orbital planes are more nearly aligned and the inner versus outer orbital periods are 3.5 and 77 d, respectively. In the absence of radial velocity observations, we were unable to calculate highly accurate masses and ages for the two systems. According to stellar isochrones TIC 167692429 might be either a pre-main sequence (MS) or an older post-MS system. In the case of TIC 220397947, our solution prefers a young pre-MS scenario.

Wyjść poza reżim imperatywu rozwojowego. Między inspiracjami Rousseau a wpływem myśli Foucaulta na współczesne studia nad dzieciństwem

The text is an attempt at a comparative analysis of the concept by Rousseau in which he proposed moving away from the directive control of the development of the child, with those concepts that can be found in poststructural childhood psychology and pedagogy, whose authors are inspired by the work of Michel Foucault. The author reconstructs the incidents of the child’s crying (Book 2) and child’s agency (Book 3) described in “Emile”, to show that Rousseau’s proposition is, in reality, manipulative and oppressive in relation to the child, being as it is based upon the all-knowing mentor, who carries out his own hidden programme. The poststructural proposition frees childhood from the regime of standardization and normalisation, taking as its starting point a problematisation of so-called, scientific developmental psychology, questioning the very term development and the role of educational institutions. The fundamental difference between the concept of the right of the child to enjoy their life in freedom formulated by Rousseau and poststructuralist concepts, is identified by the author in terms of four areas: certainty “versus” the uncertainty of deciding(differences in status given to the thesis and the project, universalism “versus” localism (differences in scope of agreed upon understandings), binary “versus” diversity (differences in accepted ontological assumptions), instruction “versus” description (differences in moral attitude towards the child).
