3D printed large amplitude torsional microactuators powered by ultrasound
Mahmut Selman Sakar, Mehdi Ali Gadiri, Junsun Hwang, Amit Yedidia Dolev
Here, we introduce a design, fabrication, and control methodology for large amplitude torsional microactuators powered by ultrasound. The microactuators are 3D printed from two polymers with drastically different elastic moduli as a monolithic compliant me ...
2024Reactive collision-free motion generation in joint space via dynamical systems and sampling-based MPC
Aude Billard, Mikhail Koptev, Nadia Barbara Figueroa Fernandez
Dynamical system (DS) based motion planning offers collision-free motion, with closed-loop reactivity thanks to their analytical expression. It ensures that obstacles are not penetrated by reshaping a nominal DS through matrix modulation, which is construc ...
Sage Publications Ltd2024Mean-field transport equations and energy theorem for plasma edge turbulent transport
This paper establishes a mean-field equation set and an energy theorem to provide a theoretical basis in view of the development of self-consistent, physics-based turbulent transport models for mean-field transport codes. A rigorous averaging procedure ide ...
Cambridge Univ Press2024Painting Taylor vortices with cellulose nanocrystals: Suspension flow supercritical spectral dynamics
We study the flow stability and spatiotemporal spectral dynamics of cellulose nanocrystal (CNC) suspensions in a custom Taylor-Couette flow cell using the intrinsic shear induced birefringence and liquid crystalline properties of CNC suspensions for flow v ...
Aip Publishing2024On the influence of flow-front orientation on stringer stiffened composite panels in water impacts
Water impacts form the critical load case for high-performance carbon fibre reinforced polymer (CFRP) racing craft. Such events produce a peaked, non-uniform pressure distribution that travels along a hull panel as it is immersed. Current design standards ...
2024Strength and timing of primary and secondary vortices generated by a rotating plate
Karen Ann J Mulleners, Diego Francescangeli
Accurate predictions of how vortices grow, evolve, and separate from aerodynamic objects are desirable for various applications ranging from autonomous aerial vehicles to wind turbines. Here, we present an experimental characterisation of the formation pro ...
2023Mechanism balancing taxonomy
Simon Nessim Henein, Florent Cosandier, Hubert Pierre-Marie Benoît Schneegans
The balancing of mechanisms consists in distributing their moving masses, inertias, and elastic components in order to achieve key mechanical properties, such as the elimination of the shaking forces and moments exported onto their supporting structure or ...
2023Gaia Focused Product Release: Radial velocity time series of long-period variables
Stephan Morgenthaler, Shuangqing Liao
Context. The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocity data planned with Data Release 4, this Focused Product Release (F ...
Les Ulis Cedex A2023The hunt for the Karman 'constant' revisited
The log law of the wall, joining the inner, near-wall mean velocity profile (MVP) in wall-bounded turbulent flows to the outer region, has been a permanent fixture of turbulence research for over hundred years, but there is still no general agreement on th ...
CAMBRIDGE UNIV PRESS2023Impact of the turbulence wavenumber spectrum and probing beam geometry on Doppler reflectometry perpendicular velocity measurements
The perpendicular propagation velocity of turbulent density fluctuations is an important parameter in fusion plasmas, since sheared plasma flows are crucial for reducing turbulence, and thus an essential input parameter for turbulent transport simulations. ...
