Item Computational modeling of GMI effect in Co-based amorphous ribbons(Springer, 2013-12) Srivastava, Hari M.; Kaya, Aslı Ayten; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Fizik Anabilim Dalı.; 0000-0002-4467-3456; W-1759-2017; 55779992300This paper presents a prediction of a giant magneto-impedance (GMI) effect on Co-based amorphous ribbons using an artificial neural network (ANN) approach based on a self-organizing feature map (SOFM). The input parameters included the compositions of Fe and Co, ribbon width and magnetizing frequency. The output parameter was the GMI effect. The results show that the proposed model can be used for estimation of the GMI effect in the amorphous ribbons.Item Hankel determinant for a subclass of Bi-univalent functions defined by using a symmetric q-derivative operator(University of Nis, 2018) Srivastava, Hari M.; Altınkaya, Şahsene; Yalçın, Sibel; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü.; 0000-0002-7950-8450; 0000-0002-0243-8263; AAA-8330-2021; AAG-5646-2021; 56543332200; 56207790300In this paper, we discuss the various properties of a newly-constructed subclass of the class of normalized bi-univalent functions in the open unit disk, which is defined here by using a symmetric basic (or q-) derivative operator. Moreover, for functions belonging to this new basic (or q-) class of normalized biunivalent functions, we investigate the estimates and inequalities involving the second Hankel determinant.Item A unified presentation of certain meromorphic functions related to the families of the partial zeta type functions and the L-functions(Elsevier, 2012-12-15) Srivastava, Hari M.; Şimşek, Yılmaz; Özden, Hacer; Cangül, İsmail Naci; Uludaǧ Üniversitesi/Fen Edebiyat Fakültesi/Matematik Bölümü.; 0000-0002-0700-5774; J-3505-2017; AAH-5090-2021; 23973633900; 57189022403The aim of this paper is to construct a unified family of meromorphic functions, which is related to many known functions such as a unified family of partial zeta type functions, a unified family of L-functions, and so on. We investigate and derive many properties of this family of meromorphic functions. Moreover, we compute the residues of this family of meromorphic functions at their poles. We also give some applications and remarks involving this family of meromorphic functions.Item A unified presentation of the generating functions of the generalized Bernoulli, Euler and Genocchi polynomials(Pergamon-Elsevier Science, 2010-11) Şimşek, Yılmaz; Srivastava, Hari M.; Özden, Hacer; Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Matematik Bölümü.; AAH-5090-2021; 23973633900The goal of this paper is to unify and extend the generating functions of the generalized Bernoulli polynomials, the generalized Euler polynomials and the generalized Genocchi polynomials associated with the positive real parameters a and b and the complex parameter beta. By using this generating function, we derive recurrence relations and other properties for these polynomials. By applying the Mellin transformation to the generating function of the unification of Bernoulli, Euler and Genocchi polynomials, we construct a unification of the zeta functions. Furthermore, we give many properties and applications involving the functions and polynomials investigated in this paper.
