The Carathéodory metric of the annulus [PDF]
Proceedings of the American Mathematical Society, 1975 An explicit formula is given for the Caratheodory metric of the annulus in the complex plane. The infinitesimal Caratheodory metric, which is just the norm of the differentiation at a point regarded as a functional on the algebra of holomorphic functions, is also determined.

An algebraic annulus theorem [PDF]
Pacific Journal of Mathematics, 2000 We present an extension of Dunwoody's theory of tracks and use it to prove an analogue of the annulus theorem for hyperbolic groups.

HEAT TRANSFER ENHANCEMENT AND PRESSURE DROP OF GROOVED ANNULUS OF DOUBLE PIPE HEAT EXCHANGER
Acta Polytechnica, 2017 This investigation was performed to experimentally investigate the enhancement of heat transfer and the friction of an annulus in a double pipe heat exchanger system with rectangular grooves in the turbulent flow regime.

Steady streaming effect on the flow of a couple stress fluid through a constricted annulus
Archives of Mechanics, 2012 The oscillatory flow of an incompressible couple stress fluid through an annulus with mild constriction at the outer wall is considered. The mean pressure drops and the mean wall shear stress are calculated across the constricted region.

On the degree of holomorphic mappings from an annulus into an annulus [PDF]
Ukrainian Mathematical Journal, 2004 Summary: We establish an estimate for the degree of a holomorphic mapping \(f: K_1\to K_2\) (here, \(K_1\) and \(K_2\) are doubly-connected domains) in terms of the modulus of a family of curves in \(K_2\). This estimate generalizes a result obtained by \textit{S. Kobayashi} [Hyperbolic manifolds and holomorphic mappings.

Strong asymmetric digraphs with prescribed interior and annulus [PDF]
, 2001 summary:The directed distance $d(u,v)$ from $u$ to $v$ in a strong digraph $D$ is the length of a shortest $u-v$ path in $D$. The eccentricity $e(v)$ of a vertex $v$ in $D$ is the directed distance from $v$ to a vertex furthest from $v$ in $D$.

On the Szegő kernel of an annulus [PDF]
Proceedings of the American Mathematical Society, 1994 In this paper we introduce a class of reproducing kernels of an annulus. Using the properties of the theta functions, we obtain a set of functional equations involving these kernels. We discuss some extremal problems associated with the functional equations.

Heat transfer characteristics of a short helical plate in a horizontal circular tube
, 2022 Enhancement techniques based on artificial roughness are used in numerous applications of heat exchangers. Heat exchange devices are essential components in complex engineering systems, such as industrial energy generation and energy conversion.
