Abstract We develop a new class of distributions, namely, the odd power generalized Weibull-G series (OPGW-GPS) distributions. present some special classes proposed distribution. Structural properties, have also been derived. conducted simulation study to evaluate consistency maximum likelihood estimates. Moreover, two real data examples on selected sets, illustrate usefulness The model outperf...

Matlab/Simulink provides a customized environment to realize a generalized modeling method previously developed by the authors for ungrounded power systems. Problems of building component models with function blocks and interconnecting them with algebraic loops in Matlab/Simulink are discussed. The system model of a reduced ring shipboard power system is built in Matlab/Simulink according to th...

the generalized principal ideal theorem is one of the cornerstones of dimension theory for noetherian rings. for an r-module m, we identify certain submodules of m that play a role analogous to that of prime ideals in the ring r. using this definition, we extend the generalized principal ideal theorem to modules.

In the field of Laurent series Q((T)), the series B = T/(e T − 1) is contained in the formal power series ring Q[[T ]]. The i-th Bernoulli number B

Recognition and classification of Power Quality Distorted Signals (PQDSs) in power systems is an essential duty. One of the noteworthy issues in Power Quality Analysis (PQA) is identification of distorted signals using an efficient scheme. This paper recommends a Time–Frequency Analysis (TFA), for extracting features, so-called "hybrid approach", using incorporation of Multi Resolution Analysis...

Definition 1.1. Given a ring R, a genus with values in R is a ring homomorphism, Ω ⊗Q→ R, where Ω is the G-bordism ring. For example, the Â-genus and L-genus are ring maps from Ω⊗Q→ Q. The Atiyah-Singer theorem shows that  can be refined to a genus Ω⊗Q→ Z. The L-genus (or signature) is defined on Ω⊗Q, and the Todd genus is defined on the complex cobordism category. We can define genera via mul...

here, we propose an optical filter and an optical power splitter based on two-dimensionalphotonic crystal all circular ring resonators. these structures are made of a square lattice ofsilicon rods with the refractive index n1=3.464 surrounded by air (with refractive indexn2=1). first, we have designed the filter and by using that, we designed a power splitter. thetransmission efficiency and qua...

A ring R is called a left APP-ring if the left annihilator lR(Ra) is right s-unital as an ideal of R for any element a ∈ R. We consider left APP-property of the skew formal power series ring R[[x;α]] where α is a ring automorphism of R. It is shown that if R is a ring satisfying descending chain condition on right annihilators then R[[x;α]] is left APP if and only if for any sequence (b0, b1, ....
