On boundary analysis for derivative of driving point impedance functions and its circuit applications
(INST ENGINEERING TECHNOLOGY-IET, 2019)
In this study, a boundary analysis is carried out for the derivative of driving point impedance (DPI) functions, which is mainly used for the synthesis of networks containing resistor-inductor, resistor-capacitor and ...
APPLICATIONS OF JACK'S LEMMA FOR CERTAIN SUBCLASSES OF HOLOMORPHIC FUNCTIONS ON THE UNIT DISC
(KOREAN MATHEMATICAL SOC, 2019)
In this paper, we give some results on zf' (z)/f(z) for the certain classes of holomorphic functions in the unit disc E = {z : vertical bar z vertical bar< 1} and on partial derivative E {z : vertical bar z vertical bar = ...
Boundary Analysis for the Derivative of Driving Point Impedance Functions
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018)
Four theorems are presented in this brief by performing boundary analysis of the derivative of driving point impedance functions evaluated at the origin. Also, the circuits corresponding to these driving point impedance ...
Bound Estimates for the Derivative of Driving Point Impedance Functions
(UNIV NIS, FAC SCI MATH, 2018)
In this paper, a boundary analysis is carried out for the derivative of driving point impedance functions, which is mainly used for synthesis of networks containing RL, RC and RLC circuits. It is known that driving point ...
SOME RESULTS OF THE CARATHEODORY'S INEQUALITY AT THE BOUNDARY
(KOREAN MATHEMATICAL SOC, 2018)
In this paper, a boundary version of the Caratheodory's inequality is investigated. We shall give an estimate below vertical bar f' (b)vertical bar according to the first nonzero Taylor coefficient of about two zeros, ...
ESTIMATES FOR HOLOMORPHIC FUNCTIONS CONCERNED WITH JACK'S LEMMA
(PUBLICATIONS L INSTITUT MATHEMATIQUE MATEMATICKI, 2018)
We investigate a boundary version of the Schwarz lemma for classes H(alpha). Also, we estimate a modulus of the angular derivative of f(z) function at the boundary point b with f (b) = b/ (beta)root 2, 0 < beta <= 1. The ...
Analytical investigation on Effect of Nanofluid Usage on Temperature Distribution in Double Pipe Heat Exchangers
(CENTRE ENVIRONMENT SOCIAL & ECONOMIC RESEARCH PUBL-CESER, 2018)
Heat exchangers are used in many industrial areas for the purpose of meeting the heat transfer requirement. The widespread use of heat exchangers has led to a number of designs for increasing the heat transfer in the heat ...
BEHAVIOR OF HOLOMORPHIC FUNCTIONS ON THE BOUNDARY OF THE UNIT DISC
(KOREAN SOC MATHEMATICAL EDUCATION, 2017)
In this paper, we establish lower estimates for the modulus of the non tangential derivative of the holomorphic function f (z) at the boundary of the unit disc. Also, we shall give an estimate below vertical bar f ''(b)vertical ...
Applications of the Jack's lemma for the meromorphic functions
(Springernature, 2021)
In this paper, we give some results on zf'(z)/f(z) for the certain classes of f(z) meromorphic functions. For the function f(z) = 1/z + c(0) + c(1)z + c(2)z(2)+ ... defined in the punctured disc U = {z : 0
ON A CLASS OF ANALYTIC FUNCTION RELATED TO SCHWARZ LEMMA
(Korean Soc Mathematical Education, 2022)
In this paper, we plan to introduce the class of the analytic functions called P (b) and to investigate the various properties of the functions belonging this class. The modulus of the second coefficient c(2) in the expansion ...
