RADIAL AND TANGENTIAL GROWTH OF CLOSE-TO-CONVEX FUNCTIONS [PDF]

Proceedings of the Edinburgh Mathematical Society, 2005
AbstractSome results are presented relating to questions raised in a recent paper by Anderson, Hayman and Pommerenke regarding the size of the set of boundary points of the unit disc at which a univalent function has a prescribed radial growth.AMS 2000 Mathematics subject classification: Primary ...

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection

Advanced Engineering Materials, EarlyView.
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Radially symmetric growth of nonnecrotic tumors [PDF]

Nonlinear Differential Equations and Applications NoDEA, 2009
The authors consider a two-dimensional system describing the growth of a tumor and evolution of cells. The mathematical model for the rate \(\psi\) and for the pressure \(p\) reads \[ \begin{cases} \Delta\psi=f(\psi), &\text{in }\,\Omega(t),\;t\geq 0,\\ \Delta p=f(\psi), &\text{in }\,\Omega(t),\;t\geq 0,\\ \psi=1, &\text{on }\,\partial\Omega(t),\;t\geq

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Influence of Temperature Distribution on Radial Growth of Compressor Disks [PDF]

Journal of Engineering for Gas Turbines and Power, 2019
Abstract For the next generation of aero-engines, manufacturers are planning to increase the overall compressor pressure ratio from the existing values around 50:1 to values of 70:1. The requirement to control the tight clearances between the blade tips and the casing overall engine-operating conditions is a challenge for the engine ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
