Mixed-precision explicit stabilized Runge-Kutta methods for single- and multi-scale differential equations

Giacomo Rosilho De Souza, Matteo Croci

Mixed-precision algorithms combine low-and high-precision computations in order to benefit from the performance gains of reduced-precision without sacrificing accuracy. In this work, we design mixed-precision Runge-Kutta-Chebyshev (RKC) methods, where high ...

Macro Annotations for Scala 3

Zhendong Ang

Macro annotations are an important feature in Scala 2 macro system. Many projects use macro annotations to implement their systems or libraries. Due to the unportability of Scala 2 macro system, Scala 3 redesigns the macro system to make it more reliable a ...

We consider the Dynamical Low Rank (DLR) approximation of random parabolic equations and propose a class of fully discrete numerical schemes. Similarly to the continuous DLR approximation, our schemes are shown to satisfy a discrete variational formulation ...

Automatic locking of a parametrically resonating, base-excited, nonlinear beam

Amit Yedidia Dolev

Described is a closed-loop control scheme capable of stabilizing a parametrically excited nonlinear structure in several vibration modes. By setting the relative phase between the spatially filtered response and the excitation, the open-loop unstable solut ...

A nonlinear model predictive control scheme for sensor fault tolerance in observation processes

Colin Neil Jones, Andrea Alessandretti

This article addresses the problem of designing a sensor fault-tolerant controller for an observation process where a primary, controlled system observes, through a set of measurements, an exogenous system to estimate the state of this system. We consider ...

Grid-aware distributed control of electric vehicle charging stations in active distribution grids

Mario Paolone, Rahul Kumar Gupta, Sherif Alaa Salaheldin Fahmy

The penetration of electric vehicle (EV) charging stations (CSs), along with the progressive connection of stochastic distributed generation, is increasing the probability of violating the power distribution grid operational constraints and deteriorate the ...

Mathematical models involving multiple scales are essential for the description of physical systems. In particular, these models are important for the simulation of time-dependent phenomena, such as the heat flow, where the Laplacian contains mixed and ind ...

SIMPLE code: Optical properties with optimal basis functions

Nicola Marzari, Gianluca Prandini, Paolo Umari

We present SIMPLE, a code developed to calculate optical properties of metallic and insulating extended systems using the optimal basis method originally proposed by E.L. Shirley in 1996. Two different approaches for the evaluation of the complex dielectri ...

An open-loop control scheme to increase the speed and reduce the viscoelastic drift of dielectric elastomer actuators

Samuel Rosset, Alexandre Poulin

We present a simple open-loop method to increase the response speed and suppress the viscoelastic creep of dielectric elastomer actuators. The parameters of the model can be extracted from two simple measurements: a strain vs. voltage ramp, and the strain ...
