Progressive Antithrombin: A Three-Phase System [PDF]
Abstract 1. Data are presented which demonstrate that progressive antithrombin activity results from the interaction of three factors: antithrombin, an antithrombin inhibitor, and a platelet factor. In plasma, the antithrombin is held inactive by combination with inhibitor so that no free antithrombic activity is present.

Improving Inverter Output Current Controller Under Unbalanced Conditions by Using Virtual Impedance
Nowadays, three-phase inverters have been commonly used in power systems, especially in renewable energy and motor drives applications. In many applications, the inverter has to generate balanced sinusoidal three-phase currents even though it is ...

Adaptive nonlinear control of single-phase to three-phase UPS system
This work deals with the problems of uninterruptible power supplies (UPS) based on the single-phase to three-phase converters built in two stages: an input bridge rectifier and an output three phase inverter.

Geometric Phase of Three-Level Systems in Interferometry [PDF]
We present the first scheme for producing and measuring an Abelian geometric phase shift in a three-level system where states are invariant under a non-Abelian group. In contrast to existing experiments and proposals for experiments, based on U(1)-invariant states, our scheme geodesically evolves U(2)-invariant states in a four-dimensional SU(3)/U(2 ...

Muscle: A Three Phase System [PDF]
The partition of sulfate, Ca++, and Mg++ across the membrane of the sartorius muscle has been studied, and the effect of various concentrations of these ions in the Ringer solution on the cellular level of Na+, K+, and Cl- has been determined. The level of the three divalent ions in toad plasma and muscle in vivo has been assayed. Muscle

Five-phase version of 12slots/8poles three-phase Synchronous Machine for Marine-propulsion [PDF]
Multiphase machines are widely used in electric marine propulsion especially because of their fault-tolerance which allows to guarantee the propulsion even if a fault occurs in the electrical system.

Effective Harmonic Cancellation Technique for a Three-Phase Four-Wire System
An excess non-linear and unbalanced load application increases the power quality (PQ) problem by injecting harmonic current. The avoidance of neutral current control creates additional PQ problems due to excess circulating current in modern 3φ4W ...
