A Stream Function Smoothing Method for the Design of MRI Gradient Coils on Non-Developable Surfaces [PDF]

Sensors, 2023
Insert gradient coils with similar imaging body shapes typically have smaller dimensions and higher spatial efficiency. This often allows the gradient coils the achievement of stronger and faster gradient fields.

Timelike Tangent Developable Surfaces and Bonnet Surfaces [PDF]

Abstract and Applied Analysis, 2016
A criterion was given for a timelike surface to be a Bonnet surface in 3-dimensional Minkowski space by Chen and Li, 1999. In this study, we obtain a necessary and sufficient condition for a timelike tangent developable surface to be a timelike Bonnet surface by the aid of this criterion.

Theories and Methods for Development of Developable Ruled Surfaces and Approximate Flattening of Non-developable Surfaces

Diségno, 2018
Geometric genesis of surfaces and knowledge of their properties are basis for solving many problems, both constructive and measurement. A developable surface can be manufactured starting from a flat “strip”, using a flexible and non-deformable material.

On the parallel surfaces of the non-developable surfaces

Қарағанды университетінің хабаршысы. Математика сериясы, 2020
In the differential geometry of curves and surfaces, the curvatures of curves and surfaces are often calculated and results are given. In particular, the results given by using the apparatus of the curve - surface pair are important in terms of what ...
