Continuous Human Activity Classification with Radar Point Clouds and Point Transformer Networks
No full textDue to numerous benefits, radar is considered as an important sensor for human activity classification. The problem of classifying continuous sequences of activities of unconstrained duration has been studied in this work. To tackle this challenge, a radar data processing method utilizing point transformer networks has been proposed. The method has been experimentally verified on a dataset of human activities, and experiments have been performed to determine its optimal implementation. Promising preliminary results on a 9-class dataset show test accuracy and macro F-1 scores in the range of 83% and 73% respectively.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Microwave Sensing, Signals & System
Turbulence modulation in particle laden homogeneous shear flow: Exact Regularized Point Particle method
No full textThis contribution presents a first evaluation of a new approach, dubbed the Exact Regularized Point Particle (ERPP) method [Gualtieri et al., Exact regularized point particle method for multi-phase flows in the two-way coupling regime, arXiv preprint arXiv:1405.6969], designed to model the modulation of turbulence by hundred thousands of small inertial particles. The approach overcomes some intrinsic difficulties which arise in some circumstances in available approaches like, e.g., the Particle In Cell (PIC) method introduced by Crowe and coworkers since 1977. Numerical results concerning a homogeneous shear flow at moderate values of the Reynolds number laden with hundred thousand of small inertial particles are discussed documenting the turbulence modification in the so-called two-way coupling regime, in a range of control parameters unaccessible to the available approaches
Gauge coupling unification in E 6 F-theory GUTs with matter and bulk exotics from flux breaking
No full textWe consider gauge coupling unification in E 6 F-Theory Grand Unified Theories (GUTs) where E 6 is broken to the Standard Model (SM) gauge group using fluxes. In such models there are two types of exotics that can affect gauge coupling unification, namely matter exotics from the matter curves in the 27 dimensional representation of E 6 and the bulk exotics from the adjoint 78 dimensional representation of E 6. We explore the conditions required for either the complete or partial removal of bulk exotics from the low energy spectrum. In the latter case we shall show that (miraculously) gauge coupling unification may be possible even if there are bulk exotics at the TeV scale. Indeed in some cases it is necessary for bulk exotics to survive to the TeV scale in order to cancel the effects coming from other TeV scale matter exotics which would by themselves spoil gauge coupling unification. The combination of matter and bulk exotics in these cases can lead to precise gauge coupling unification which would not be possible with either type of exotics considered by themselves. The combination of matter and bulk exotics at the TeV scale represents a unique and striking signature of E 6 F-theory GUTs that can be tested at the LHC
Turbulence modulation in particle laden pipe flow: Exact regularized point particle method
No full textMany technological applications are characterized by turbulent bounded flows with dispersed particles. For high mass load (particle/fluid mass ratio) a significant inter-phase momentum exchange occurs (two-way coupling regime), inducing a significant alteration of the turbulent field which, in turn, modifies the dynamics of the suspended phase. Aim of the present study is exploring the potentially of recently developed momentum coupling method, dubbed the Exact Regularized Point Particle (ERPP) method, in reproducing via Direct Numerical Simulation (DNS) the detailed dynamics of a particles laden turbulent pipe flow. The comparison with available experimental and numerical data confirms the ability of the new approach in reproducing the relevant dynamics also in parameter ranges which are unaccessible to standard techniques
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Teaching 'European literature' through the history of criticism: The concept of "model author" as the starting point | Poučevanje Evropske literature prek zgodovine kritike: Pojem zglednega avtorja kot izhodišče
No full textThe starting point of the article is the intersection of identities formed as a consequence of relationships among different cultures. The author refers to some of the main 20th century representatives of literary criticism, based upon the concept of “model author/text”, and considering some other concepts, and verifies their applicability to the didactics of comparative literature. This should enable appropriate understanding of European literature (territorially determined as well) and its relationship to different, not only European literatures and cultural identitie

Bézout domains and lattice-valued modules
No full textLet B be a commutative Bézout domain and let MSpec(B) be the maximal spectrum of B. We obtain a Feferman-Vaught type theorem for the class Mod-B of all (right) B-modules. We analyze the definable sets in terms, on the one hand, of the definable sets in the classes Mod-BM, where BM ranges over the localizations of B at M, M ∈ MSpec(B), and on the other hand, of the constructible subsets of MSpec(B). This allows us to derive decidability results for the class Mod-B, in particular when B is the ring Z of algebraic integers or one of the rings Z ∩ R, Z ∩ Qp
