This paper describes the modeling of the feedback control and rotational stabilization of the resistive wall mode (RWM) in tokamaks. A normal mode theory for the feedback stabilization of the RWM has been developed for an ideal plasma with no toroidal rotation. This theory has been numerically implemented for general tokamak geometry and applied to the DIII-D tokamak. It is found that feedback ...
We here demonstrate the potentialities of pigtailed electrooptic probes to perform vectorial electric field characterizations dielectric barrier discharges (DBDs). The analysis leads accurate determination breakdown voltage and associated in vicinity discharge. A polarimetric DBDs is proposed due real-time measurement longitudinal radial components vector. Moreover, transition from capacitive r...
When simulating resistive-capacitive circuits or electroquasistatic problems where conductors and insulators coexist, one observes that large time steps low frequencies lead to numerical instabilities, which are related the condition number of system matrix. Here, we propose several stable formulations by scaling equation systems. This enables a reliable calculation solutions for very (even sta...
This paper presents a new control scheme of voltage source active filter (AF) which compensates simultaneously the harmonics and reactive power of non-linear loads. The reference compensating currents are estimated from computed reference supply currents and sensed load currents. Reference supply currents are estimated using active power of the load and the AF. A hysteresis or carrier based PWM...
Presented in this report is an overview of robotic sensors, many of which are in experimental stages. Two main sensor types are discussed: contact and noncontact. Descriptions of the physical measurements. how they are measured, and operating principles of specific devices are provided for both types of sensors. Contact, or tactile, sensors comprise three groups: touch, proximity, and slip sens...
This study aimed to investigate a multimodal modulation scheme that takes into account the wide range of output characteristics, numerous constraints, and complex working conditions in wireless charging electric vehicles. Key electrical parameters variables secondary stages vehicle power transfer (EV-WPT) systems were evaluated based on capacitive, inductive, resistive impedance modes. The limi...
We show that a harmonic lattice model with amplifying and attenuating elements, when coupled to two thermal baths, exhibits unique heat transport properties. Some of these novel features include anomalous nonequilibrium steady-state heat currents, negative differential thermal conductance, as well as nonreciprocal heat transport. We find that when these elements are arranged in a PT-symmetric m...
Delay faults are an increasingly important test challenge. Traditional delay fault models are incomplete in that they only model a subset of delay defect behaviors. To solve this problem a combined delay fault (CDF) model has been developed, which models delay faults caused by the combination of spot defects, parametric process variation, and capacitive coupling. The spot defects are modeled as...
Partial Element Equivalent Circuit (PEEC) methods, for solving electromagnetic problem ,uses two discretizations, to volume cells for resistive-inductive partitions and to surface cells for capacitive partitions. Three-dimensional (3-D) problem geometry is partitioned to hexahedral volume cells. Around outer surface of these cells, with half-cell shift, surface cells will take place. When FastC...
