In the first part we give a short proof for an old result by Beltrami and Dini on ruled surfaces satisfying a nontrivial relation between \(H\) and \(K\). In the second part we solve the analogous problem for the case of a relation between \(H\) and the inner curvature \(K_{II}\) of the second fundamental form.

General Principles for Formation of Ruled Surfaces. Part 3
Geometry & Graphics, 2019We continue to consider the formation of ruled surfaces with a single method of their formation. In the first and second parts have been introduced more than forty options for specifying surfaces.

Tool path planning is a key to ensure high machining quality and productivity in 5-axis flank milling of ruled surfaces. Previous studies have shown that optimization-driven tool path planning can effectively reduce the geometrical errors on the finished

Ill ÖZET Bu çalışmada, RJ de verilen bir yüzey üzerindeki eğrinin Darboux üçyüzlüsünde invaryant büyüklüklerinden faydalanılarak, doğrular uzayındaki bir regle yüzeyi belirleyen diferansiyel denklem sistemi kurulmuştur. Bu denklem sisteminin genel çözümü bulunamamıştır.

The modification of the absorption, emission, and Raman scattering intensities of molecules near metal surfaces is discussed with emphasis on the last. These modifications are usually referred to as surface selection rules. We show that in Raman scattering, the ‘‘rule,’’ which states that only those modes will be active which belong to the irreducible ...

Synthesis of Equations For Ruled Surfaces With Two Curvilinear And One Rectangular Directrixes
Geometry & Graphics, 2018Ruled surfaces have long been known and are widely used in construction, architecture, design and engineering. And if from the technical point of view the developable surfaces are more attractive, then architecture and design successfully experiment with

Ruled singular minimal surfaces
Journal of Geometry and PhysicsThe paper is concerned with the classification of singular minimal surfaces. In the first part the authors give some basic concepts and results of immersed surfaces in Euclidean and Lorentzian spaces. In the second part they study singular minimal surfaces in \(\mathbb{R}^{3}\) and prove that the only ruled singular minimal surfaces in \(\mathbb{R}^{3}\
