commutation 
For unbounded operators A, B and C in general, the commutation relation [A, B] =


However, a ripple current occurs in the inactive phase due to the diode freewheeling during the noncommutation period in the traditional pulse width modulation (PWM) methods, which aggravates the torque ripples.


A new PWM method is proposed in this paper to eliminate the diode freewheeling during the noncommutation period in the inactive phase.


An algorithm is designed for computing "throughput" service quality characteristics of circuitswitched rerouting networks with regard for the influence of undetected failures in commutation devices if crankbacking is used for switching.


It is shown that an arbitrary grouped pelement permutation can be implemented in a conflictfree way through the commutation of channels on the double pary multiring or the double pary hypercube.


The Use of a Magnetic Switch for Commutation of HighCurrent Pulse Circuits


In this paper, the naturalness of the appearance of the group approach in the study of problems of algebraic commutation is considered.


Special attention is paid to an example of commutation obtained from the icosahedral equation.


We study a class of algebras with nonLie commutation relations whose symplectic leaves are surfaces of revolution: a cylinder or a torus.


Nonlinear Commutation Relations: Representations by PointSupported Operators


We present a class of nonLie commutation relations admitting representations by pointsupported operators (i.e., by operators whose integral kernels are generalized pointsupported functions).


The inertialess nature of the beam coupling makes it possible to use the holograms of this type for ultrafast commutation of the information fluxes in optical computers and communication lines.


It has been found that, by extending the QRPA including fermion commutation relations, better agreement with 2νββdecay experiments is achieved.


The commutation relations between the generators xi, dxi, and d2xi of the algebra of differential forms, among dxi, and among d2xi, as well as between noncommutative derivatives with generators, are found.


Conserved operators are found, and their commutation relations are derived.


Here, the noncommutativity of these operators is due to the effect of interparticle forces and arises as a natural generalization of the usual commutation relation between the coordinate and momentum operators for a single particle.

The commutation quality factor of electrically controlled microwave device components


Various circuit components based on electrically controlled capacitors can be compared using an integral criterion, called the commutation quality factor and determined by the efficiency of capacitance tuning and the losses in the control device.
