Massive Multiple-Input Multiple-Output (MIMO) communication systems are being investigated intensively for positioning services. Enhancing the accuracy on these services in terms of accurate positioning of users is an important goal to improve related applications in the future. Convolutional Neural Networks (CNNs) has been proposed to infer the position of a user from Channel State Information (C

We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. The partial derivatives in the chain rule formula are rela

Abstract in French Cette contribution décrit l’aide potentielle que le concept de table interactive apporte à certaines tâches du concepteur en mécanique. Le travail de recherche présenté n’en est qu’à sa genèse. La problématique est la suivante : une fois la faisabilité d’une idée de produit (le concept) est prouvée, le concepteur développe l’architecture et les composants du produit (embodiment This paper describes the potential help that the interactive desktop concept can bring to the execution of embodiment design tasks. The presented project is still in its infancy. The research framework is the following: once a product concept has been approved, the mechanical design engineer develops the product architecture and product part (also called embodiment design). Sketches at that level

Ny forskning bekräftar att förändrad användning av sociala medier främjar psykisk hälsa. Försökspersoner som minskade sin sociala mediekonsumtion till en halvtimme om dagen upplevde ökat välmående och självkänsla. Men även de som gick från att vara aktiva användare till mer passiva "scrollare" kunde rapportera hälsoeffekter som förbättrat fokus och koncentration i vardagen. Forskarna vid Instituti

AMDS.GlOW36 Language Faculty, Complexity Reduction and Symmetry Breaking Anna Maria Di Sciullo, Université du Québec à Montréal 1. I assume that the Language Faculty is stable, it does not vary though time and space, and that language development requires experience (Chomsky 1995, 2005, 2011). I develop the view that language evolutionary development is the result of the interaction of the languag

The objective of this study was to examine the relationship between self-reported and professionally assessed functional limitations in community-dwelling very old individuals. In total, 306 single-living adults aged 81-90 years were included in this cross-sectional study. The main outcome measure was the presence and absence of self-reported and professionally assessed functional limitations. A s

OBJECTIVE: Mapping coreceptor epitopes used by the prototypic R5 and X4 strains, HIV-1BaL and HIV-1IIIB, in comparison with epitopes involved in the activation and signaling induced by the natural ligands, RANTES and SDF-1beta. DESIGN: Receptor hybrids between CCR5 and CXCR4 were constructed. METHODS: Using single-overlap and extension PCR, increasing portions of CCR5 were replaced with correspond
