Probabilistic assessment of the process-noise covariance matrix of discrete Kalman filter state estimation of active distribution networks

Mario Paolone, Marco Pignati, Lorenzo Zanni, Styliani Sarri

The accuracy of state estimators using the Kalman Filter (KF) is largely influenced by the measurement and the process noise covariance matrices. The former can be directly inferred from the available measurement devices whilst the latter needs to be asses ...

Accurate Indoor Localization with Ultra-Wideband using Spatial Models and Collaboration

Alcherio Martinoli, Amanda Stella Markowska Prorok

Ultra-wideband (UWB) localization is a recent technology that performs competitively with many indoor localization methods currently available. Despite its desirable traits, such as potential high accuracy and high material penetrability, the resolution of ...

Matrix Recipes for Hard Thresholding Methods

Volkan Cevher, Anastasios Kyrillidis

In this paper, we present and analyze a new set of low-rank recovery algorithms for linear inverse problems within the class of hard thresholding methods. We provide strategies on how to set up these algorithms via basic ingredients for different configura ...

Joint product assortment, inventory and price optimization to attract loyal and non-loyal customers

Ralf Seifert, Jean-Sébastien Tancrez, Argyro Katsifou

In this paper, we analyze the emerging retail practice of carrying a combined product assortment consisting of both regular "standard" products and more fashionable and short-lived "special" products. The purpose of this practice is to increase store traff ...

Are current bridge load modelling techniques realistic for existing road bridges?

Mark Anthony Treacy

Road traffic loading is a highly variable process with a wide range of complex variables to consider. Consequently, various simplifying assumptions are required to efficiently model heavy traffic events for bridge safety verification, which reduce the accu ...

Multimodal Reranking of Content-based Recommendations for Hyperlinking Video Snippets

Andrei Popescu-Belis, Nikolaos Pappas, Maryam Habibi

In this paper, we present an approach for topic-level search and hyperlinking of video snippets, which relies on contentbased recommendation and multimodal re-ranking techniques. We identify topic-level segments using transcripts or subtitles and enrich th ...

Beyond Knowledge Tracing. Modeling Skill Topologies with Bayesian Networks

Modeling and predicting student knowledge is a fundamental task of an intelligent tutoring system. A popular approach for student modeling is Bayesian Knowledge Tracing (BKT). BKT models, however, lack the ability to describe the hierarchy and relationship ...

Improving Fatigue Evaluations of Structures Using In-Service Behavior Measurement Data

Ian Smith, James-Alexandre Goulet, Romain Pasquier, Claire Acevedo

Conservative models and code practices are usually employed for fatigue-damage predictions of existing structures. Direct in-service behavior measurements are able to provide more accurate estimations of remaining-fatigue-life predictions. However, these e ...
