Active feedback control has been used in the HBT-EP tokamak to control the growth of the n=1 resistive wall mode. These experiments were carried out using a set of thin stainless-steel wall segments with magnetic diffusion time of ~0.4 ms positioned near the plasma boundary. In plasmas that would normally exhibit a strong ideal n = 1 external kink mode without a nearby conducting wall, the resi...

Conclusions: In this Letter, I have presented a resistive network using a feedback mechanism able to extract phase information from an image for depth evaluation. The information, related to a single frequency, can be properly organised by a further network, or the resistive network itself can be tuned to a more complex behaviour (e.g. regularisation of data). The design of this network makes s...

BACKGROUND Management of individual triggers is suboptimal in practice. In this project, we investigated the impact of symptom perception interventions on asthma trigger identification and self-reported asthma quality of life. METHODS Children with asthma (n=227) participated in three asthma education sessions and then were randomized first to one of three home monitoring conditions (symptom ...

Large pulsar glitches seem to be common to all radio pulsars and to exhibit a universal behaviour connecting the rate of occurrence, event size and interglitch relaxation that can be explained if the glitches are due to angular momentum exchange in the neutron star. This has implications for the energy dissipation rate. The large timing excursions observed in SGRs are not similar to the pulsar ...

A general circuit formulation of resistive wall mode ~RWM! feedback stabilization developed by Boozer @Phys. Plasmas 5, 3350 ~1998!# has been used as the basis for the VALEN computer code that calculates the performance of an active control system in arbitrary geometry. The code uses a finite element representation of a thin shell structure in an integral formulation to model arbitrary conducti...

In this paper we present a novel system for tactile actuation in stylus-based musical interactions. The proposed controller aims to support rhythmical musical performance. The system builds on resistive force feedback, which is achieved through a brakeaugmented ball pen stylus on a sticky touch-sensitive surface. Along the device itself, we present musical interaction principles that are enable...

In this paper, two new high speed low power current comparators are proposed. The first comparator uses resistive load amplifiers in gain stage which is modified by including a resistive feedback in the gain stage for better speed. Simulations have been carried out on SPICE using TSMC 0.18um CMOS technology. The results show a resolution of ± 50 nA for both the comparators and an improved delay...

When subjects learn a novel motor task, several sources of feedback (proprioceptive, visual or auditory) contribute to the performance. Over the past few years, several studies have investigated the role of visual feedback in motor learning, yet evidence remains conflicting. The aim of this study was therefore to investigate the role of online visual feedback (VFb) on the acquisition and retent...

Developing simulation models for electromagnetic field problems often deals with approximations of the full set Maxwell’s equations, to obtain performant methods. This is also case so-called Darwin model, which has capability including resistive, inductive, and capacitive effects without need solving full-wave equations. However, an issue difficulty prescribing realistic excitations e.g., via a...
