Resumen
In this work, a low-cost low-power navigation solution for autonomous underwater vehicles is introduced utilizing a Micro-Electro-Mechanical System (MEMS) inertial sensor and an ultra short baseline (USBL) system. The complete signal processing is implemented on a cheap 16-bit fixed-point arithmetic microcontroller. For data fusion and calibration, an error state Kalman filter in square root form is used, which preserves stability in case of rounding errors. To further reduce the influence of rounding errors, a stochastic rounding scheme is applied. The USBL measurements are integrated using t

Resumen
Abstract Motivated by recent advances in operational weather forecasting, we study the efficacy of low-precision arithmetic for climate simulations. We develop a framework to measure rounding error in a climate model, which provides a stress test for a low-precision version of the model, and we apply our method to a variety of models including the Lorenz system, a shallow water approximation for flow over a ridge, and a coarse-resolution spectral global atmospheric model with simplified parameterizations (SPEEDY). Although double precision [52 significant bits (sbits)] is standard across opera

Resumen
For this issue, I am pleased to present a tutorial by Will Ma on using randomized rounding to design online policies. Randomized rounding has of course been used extensively in the design of approximation algorithms and also to approximately solve sequential stochastic optimization problems. Will describes several examples that show how randomized rounding can be used in this context. As always, I would like to invite more contributions to this column, be it surveys, conference reports, or technical articles related to online algorithms and competitive analysis.

Resumen
Abstract Use of generalized stochastic dominance (GSD) requires one to place lower and upper bounds on the risk aversion coefficient. This study showed that breakeven risk aversion coefficients found assuming the exponential utility function delineate the places where GSD preferences switch between prospects. However, between these break points, multiple, overlapping GSD intervals can be found. Consequently, when one does not have risk aversion coefficient information, discovery of breakeven coefficients instead of GSD use is recommended. The investigation also showed GSD results are insensiti

Resumen
L'idée de considérer les erreurs d'arrondi comme des variables aléatoires n'est pas nouvelle. Basées sur des outils tels que l'indépendance des variables aléatoires ou le théorème central limite, plusieurs propositions ont démontré des bornes d'erreur en O(√n). Cette thèse est dédiée à l'étude de l'arrondi stochastique (SR) en tant que remplaçant du mode d'arrondi déterministe par défaut. Tout d'abord, nous introduisons une nouvelle approche pour dériver une borne probabiliste de l'erreur en O(√n), basée sur le calcul de la variance et l'inégalité de Bienaymé-Chebyshev. Ensuite, nous développo

Resumen
De nombreux travaux sont consacrés à la performance des simulations numériques, or il est important de tenir compte aussi de l'impact des erreurs d'arrondi sur les résultats produits. Ces erreurs d'arrondi peuvent être estimées grâce à l'Arithmétique Stochastique Discrète (ASD), implantée dans la bibliothèque CADNA. Les algorithmes compensés permettent d'améliorer la précision des résultats, sans changer le type numérique utilisé. Ils ont été conçus pour être généralement exécutés en arrondi au plus près. Nous avons établi des bornes d'erreur pour ces algorithmes en arrondi dirigé et montré qu

Resumen
Abstract Vowel harmony (VH) is a cross-linguistically pervasive phenomenon that ranges on a language-specific basis from a highly productive process to a vestigial property reflected in statistical patterns in the lexicon and morphologically restricted alternations. There are several types of VH that differ with respect to the phonological feature that spreads. The typologically most common VH systems operate along the front–back (palatal harmony), height, rounding (labial harmony), and tongue-root (advanced tongue root/restricted tongue root harmony) dimensions, although other varieties of VH
