این پایان نامه، یک کنترلر بهینه ی ردیاب متغیر با زمان را برای یک statcom متصل به باس بار شبکه پیشنهاد می دهد. کنترلرهای بهینه شامل یک (زاویه ی کنترلی ?) و یا دو ورودی کنترلی (زاویه ی کنترلی ? و شاخص مدولاسیون دامنه a_m) می باشند. طراحی کنترلرهای بهینه بر مبنای مدل های فضای حالت میانگینی صورت می گیرد که بر اساس ولتاژها و یا جریان های بار به عنوان ورودی های اغتشاشی مدل در کنار ورودی های کنترلی، گ...
Many optimization problems can be reduced to a problem with an increasing and co-radiant objective function by a suitable transformation of variables. Functions, which are increasing and co-radiant, have found many applications in microeconomic analysis. In this paper, the abstract convexity of positive valued affine increasing and co-radiant (ICR) functions are discussed. Moreover, the ...
Abstract. In this paper, we define the notion of C*-affine maps in the unital *-rings and we investigate the C*-extreme points of the graph and epigraph of such maps. We show that for a C*-convex map f on a unital *-ring R satisfying the positive square root axiom with an additional condition, the graph of f is a C*-face of the epigraph of f. Moreover, we prove som...
in this paper, we first introduce the notion of $c$-affine functions for $c> 0$.then we deal with some properties of strongly convex functions in real inner product spaces by using a quadratic support function at each point which is $c$-affine. moreover, a hyers–-ulam stability result for strongly convex functions is shown.
let $fneq1,3$ be a positive integer. we prove that there exists a numerical semigroup $s$ with embedding dimension three such that $f$ is the frobenius number of $s$. we also show that the same fact holds for affine semigroups in higher dimensional monoids.
Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...
we examine the symplectic group $sp_{2m}(q)$ and its correspondingaffine subgroup. we construct the affine subgroup and show that itis a split extension. as an illustration of the above we study theaffine subgroup $2^5{:}sp_4(2)$ of the group $sp_6(2)$.
The article introduces cyclic dilation groups and finite affine groups for prime integers, and as an application of this theory it presents a unified group theoretical approach for the cyclic wavelet transform (CWT) of prime dimensional periodic signals.
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
