The p-q theory for active filter control: some problems and solutions [PDF]
The instantaneous active and reactive power theory or the p-q Theory is widely used to design controllers for active filters. This paper deals with some problems due to the misinterpretations of this theory. A historical background of the theory is presented and the problem caused by distorted voltages at the point of common connection (PCC) is ...

Positive solutions for nonlocal problems of nonlinear (p,q)- difference equations
In order to improve the basic theory of boundary value problems for nonlinear quantum difference equations,in this paper,we study the solvability of nonlocal problems for second order three-point nonlinear (p,q)-difference equations.Firstly,the Green ...

The linear complexity of whiteman's generalized cyclotomic sequences of period p {m+1}q n+1 [PDF]
In this paper, we mainly get three results. First, let p, q be distinct primes with \gcd ((p-1)p,(q-1)q)=\gcd (p-1,q-1)=e ; we give a method to compute the linear complexity of Whiteman's generalized cyclotomic sequences of period p^{m+1}q n+1.

Chern-Simons Theory on L(p,q) Lens Spaces and Localization [PDF]
Using localization technique, we calculate the partition function and the expectation value of Wilson loop operator in Chern-Simons theory on general lens spaces L(p,q)(including S2XS1). Our results are consistent with known results.

Digital controller for active power filter based on P-Q theory under non-ideal main voltages [PDF]
This paper proposes a control strategy active power filter under non-ideal main voltages. The P-Q Theory is used to generate three-phase active power filter reference currents, but the P-Q Theory has a weakness when implemented under non ideal main ...

(p,q)-Baskakov-Kantorovich Operators [PDF]
In the last decade the applications of quantum calculus in the field of approximation theory is an active area of research. The (p,q)-calculus is further extension of q-calculus, which provides a new direction for researchers.

Electronic Thesis or DissertationWe define two classes of algebras P- and Q-, which are derived from the definitions of BCK- and BCI- algebras. The birth of P-algebras is based on the symmetric difference in set theory.
