Combined influence of inertia, gravity, and surface tension on the linear stability of Newtonian fiber spinning

The draw resonance effect appears in fiber spinning processes if the ratio of take-up to inlet velocity, the so-called draw ratio, exceeds a critical value and manifests itself in steady oscillations of flow velocity and fiber diameter. We study the effect ...

At off-design operating operations, cavitating flow is often observed in hydraulic machines. The presence of a cavitation vortex rope may induce draft tube surge and electrical power swings at part load and full load operations. The stability analysis of t ...

Order/Disorder Dynamics in a Dodecanethiol-Capped Gold Nanoparticles Supracrystal by Small-Angle Ultrafast Electron Diffraction

Francesco Stellacci, Fabrizio Carbone, Giulia Fulvia Mancini, Tatiana Latychevskaia, Javier Reguera Gomez, Francesco Pennacchio

The design and the characterization of functionalized gold nanoparticles supracrystals require atomically resolved information on both the metallic core and the external organic ligand shell. At present, there is no known approach to characterize simultane ...

Incremental motion learning with locally modulated dynamical systems

Aude Billard, Klas Jonas Alfred Kronander

Dynamical Systems (DS) for robot motion modeling are a promising approach for efficient robot learning and control. Our focus in this paper is on autonomous dynamical systems, which represent a motion plan without dependency on time. We develop a method th ...

Real-time full body motion imitation on the COMAN humanoid robot

Auke Ijspeert, Florin Dzeladini, Jesse van den Kieboom

On-line full body imitation with a humanoid robot standing on its own two feet requires simultaneously maintaining the balance and imitating the motion of the demonstrator. In this paper we present a method that allows real-time motion imitation while main ...

The motion of a 2D pendulum in a channel subjected to an incoming flow

François Gallaire, Andrea Fani

The flow around a tethered cylinder subjected to an incoming flow transverse to its main axis and confined in a channel is investigated by means of global stability analysis of the full coupled body-fluid problem. When the cylinder is strongly confined (ra ...

Plug-and-Play Model Predictive Control based on robust control invariant sets

Giancarlo Ferrari Trecate, Marcello Farina

We consider the problem of designing decentralized controllers for large-scale linear constrained systems composed by a number of interacting subsystems. As in (Riverso et al., 2013) (i) the design of local controllers requires limited transmission of info ...

Dynamic stability and noise margins of SRAM arrays in nanoscaled technologies

Adam Shmuel Teman

SRAM stability is one of the primary bottlenecks of current VLSI system design, and the unequivocal supply voltage scaling limiter. Static noise margin metrics have long been the de-facto standard for measuring this stability and estimating the yield of SR ...

Calcium aluminate cements (CAC) are often used in combination with calcium sulfate and Portland cement for special applications where rapid setting, rapid drying and shrinkage compensation are required. A growing fraction of the clinker, which has the high ...

We present our studies on a compact high-performance continuous wave (CW) double-resonance (DR) rubidium frequency standard in view of future portable applications. Our clock exhibits a short-term stability of 1.4 x 10(-13) tau(-1/2), consistent with the s ...
