Information-driven transitions in projections of underdamped dynamics
Daniel Maria Busiello, Giorgio Nicoletti, Amos Maritan
Low-dimensional representations of underdamped systems often provide useful insights and analytical tractability. Here, we build such representations via information projections, obtaining an optimal model that captures the most information on observed spa ...
AMER PHYSICAL SOC2022Investigation of the Time Resolution Set Up Used to Compute the Full Load Vortex Rope in a Francis Turbine
François Avellan, Cécile Münch-Alligné, Arthur Tristan Favrel, Andres Müller
The flow in a Francis turbine at full load is characterised by the development of an axial vortex rope in the draft tube. The vortex rope often promotes cavitation if the turbine is operated at a sufficiently low Thoma number. Furthermore, the vortex rope ...
2021Real-Time Multi-Ion Detection in the Sweat Concentration Range Enabled by Flexible, Printed, and Microfluidics-Integrated Organic Transistor Arrays
Danick Briand, Silvia Demuru, Brince Paul Kunnel
Organic electrochemical transistors (OECTs) show remarkable promise as biosensors, thanks to their high signal amplification, simple architecture, and the intrinsic flexibility of the organic material. Despite these properties, their use for real-time sens ...
WILEY2020Understanding and Mitigating Latency Variability of Latency-Critical Applications
A major theme of IT in the past decade has been the shift from on-premise hardware to cloud computing. Running a service in the public cloud is practical, because a large number of resources can be bought on-demand, but this shift comes with its own set of ...
EPFL2020Nonlinear piezoelectric vibration energy harvester with frequency-tuned impacting resonators for improving broadband performance at low frequencies
Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Robert Andrew Lockhart
The paper reports on a nonlinear frequency up-converting vibration energy harvester with enhanced broadband performance below 50 Hz, which is attained by leveraging vibro-impact interaction between two high-frequency piezoelectric generators and two low-fr ...
IOP PUBLISHING LTD2019A Robotic Glenohumeral Simulator for Investigating Prosthetic Implant Subluxation
Kamiar Aminian, Alexandre Terrier, Alain Farron, Arash Arami, Matteo Mancuso
Total shoulder arthroplasty (TSA) is an effective treatment for glenohumeral (GH) osteoarthritis. However, it still suffers from a substantial rate of mechanical failure, which may be related to cyclic off-center loading of the humeral head on the glenoid. ...
2019Parametric study of Pneumatic Circuit Model for Powering and Controlling Soft Pneumatic Actuators
Jamie Paik, Sagar Dattatray Joshi
Soft pneumatic actuator (SPA) based devices often use heuristic approaches for designing the power and control system, which are not necessarily optimized for the application. Especially in portable applications, due to constraints on the overall size and ...
2018Modeling of EMP Coupling to Lossless MTLs in Time Domain Based on Analytical Gauss-Seidel Iteration Technique
This paper provides an efficient way to simulate the transient electromagnetic field coupling to overhead multi conductor transmission lines in time domain based on an analytical iterative technique. The method is entirely in time domain and therefore can ...
2018Rise time reduction of thermal actuators operated in air and water through optimized pre-shaped open-loop driving
Georg Fantner, Nahid Hosseini, Tom Larsen
Electrothermal actuators have many advantages compared to other actuators used in micro-electro-mechanical systems (MEMS). They are simple to design, easy to fabricate and provide large displacements at low voltages. Low voltages enable less stringent pass ...
2017Time-Projection control on 3LP, a simple idea to deal with intermittent pushes online
In this article, we propose a new controller for recovering intermittent pushes during bipedal locomotion. We use 3LP as a template model which can provide closed-form solutions for state evolution. The idea behind our controller is to project the perturbe ...
