Current control of unbalanced electrical systems
IEEE Transactions on Industrial Electronics, 2001The vector modeling approach is employed to describe the behavior of unbalanced three-phase (three-wire), unbalanced two-phase and single-phase systems. In the case of single-phase systems, a fictitious circuit is introduced in order to create the vector model.

Electric current control of spiral wave dynamics
Physica D: Nonlinear Phenomena, 1992The control of spiral wave parameters by electric current was investigated in the Belousov-Zhabotinsky (BZ) reaction. It was found that the wavelength and the period of spiral waves increase by a factor of up to 3 with electric current (both dc and ac).

Robust currents control in the electric drive
2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017The control systems of modern electric drives are built with using the principle of subordinate control, therefore the quality and accuracy of control of all external loops largely depends on internal control loops. In the article a typical, which is widely used in practice, and robust current control systems, which is obtained based on of a general ...

Controlling Atomic Joints between Carbon Nanotubes by Electric Current
Physical Review Letters, 2009Using a transmission electron microscope and a nanomanipulator, we explored the early head-to-head coalescence of two capped carbon nanotubes (CNTs) under induction of electric current. We measured detaching forces for coalesced CNTs, showing discrete identifiable values attributable to van der Waals interaction, single sp2-like bonds, and double sp3 ...

Controlled Levitation of Colloids through Direct Current Electric Fields
Langmuir, 2017We report the controlled levitation of surface-modified colloids in direct current (dc) electric fields at distances as far as 75 μm from an electrode surface. Instead of experiencing electrophoretic deposition, colloids modified through metallic deposition or the covalent bonding of poly(ethylene glycol) (PEG) undergo migration and focusing that ...

CHAOS CONTROL BY ELECTRIC CURRENT IN AN ENZYMATIC REACTION
International Journal of Neural Systems, 1996We apply the continuous delayed feedback method of Pyragas to control chaos in the enzymatic Peroxidase-Oxidase (PO) reaction, using the electric current as the control parameter. At each data point in the time series, a time delayed feedback function applies a small amplitude perturbation to inert platinum electrodes, which causes redox processes on ...

Controlling Cell Behavior Electrically: Current Views and Future Potential
Physiological Reviews, 2005Direct-current (DC) electric fields are present in all developing and regenerating animal tissues, yet their existence and potential impact on tissue repair and development are largely ignored. This is primarily due to ignorance of the phenomenon by most researchers, some technically poor early studies of the effects of applied fields on cells, and ...

Current Control by Electrically Active Grain Boundaries
1989The electric properties of grain boundaries are discussed for the general case, where the behavior of the potential barrier between the grains is controlled by an arbitrary number and distribution in energy of bulk and interfacial defects. Special emphasis is put on the high field phenomena, where minority carriers can be generated by hot electrons ...

Safe control of palmoplantar hyperhidrosis with direct electrical current
International Journal of Dermatology, 2002AbstractBackground Primary (idiopathic) hyperhidrosis is a benign disease of unknown etiology, leading to the disruption of professional and social life and emotional problems. A variety of treatment methods have been used to control or reduce the profuse sweating.
