3-D Analytical Model of Axial-Flux Permanent Magnet Machine With Segmented Multipole-Halbach Array
IEEE Access, 2023 This paper presents a 3-D analytical model of an axial-flux permanent magnet (AFPM) machine with a segmented multipole-Halbach PM array. Closed-form solutions are self-consistently derived in terms of modified Bessel functions of the first- and the ...

Infinite divisibility of solutions to some self-similar integro-differential equations and exponential functionals of L\'evy processes [PDF]
, 2009 We provide the increasing eigenfunctions associated to spectrally negative self-similar Feller semigroups, which have been introduced by Lamperti. These eigenfunctions are expressed in terms of a new family of power series which includes, for instance ...

On determinants of modified Bessel functions and entire solutions of double confluent Heun equations [PDF]
, 2016 We investigate the question on existence of entire solutions of well-known linear differential equations that are linearizations of nonlinear equations modeling the Josephson effect in superconductivity. We consider the modified Bessel functions $I_j(x)$

Modified Dini functions: monotonicity patterns and functional inequalities [PDF]
, 2016 We deduce some new functional inequalities, like Turan type inequalities, Redheffer type inequalities, and a Mittag-Leffler expansion for a special combination of modified Bessel functions of the first kind, called modified Dini functions.
