The Pedal Curves Generated by Alternative Frame Vectors and Their Smarandache Curves
SymmetryIn this paper, pedal-like curves are defined resulting from the orthogonal projection of a fixed point on the alternative frame vectors of a given regular curve. For each pedal curve, the Frenet vectors, the curvature and the torsion functions are found to provide the common relations among the main curve and its pedal curves.

Shape optimization of space frame structures for maximizing a natural frequency
Nihon Kikai Gakkai ronbunshu, 2014 This paper presents a non-parametric, or a node-based, shape optimization method for designing the optimal geometry of a space frame structure for a natural frequency problem. For a frame structure composed of arbitrarily curved linear elastic members, a

L’Anjou : la tuile au pays de l’ardoise
Archéologie MédiévaleAt the edge of both the Armorican Massif and the Paris Basin, the Anjou region is well known for its slated roofs. Though slate deposits are numerous and well stocked, other roofing materials have been used concurrently in restricted areas ...

Bishop Frames of Salkowski Curves in E3
Bitlis Eren Üniversitesi Fen Bilimleri DergisiIn this study, alternative, type-1 Bishop, type-2 Bishop and N-Bishop frames of Salkowski curves in E3 are calculated. Moreover, curvatures, Darboux and pol vectors of these frames are found. Also, relationships between the Bishop frames, Darboux vectors and pole vectors are given.

On translation surfaces of framed curves
, 2023 Abstract In this study, we study translation surfaces of framed curves in the 3-dimensional Euclidean space E3. First, we compute some important equations and geometric invariants such as first and second fundamental forms, Gauss equations, Christoffel symbols, Mainardi-Codazzi equations and Egregium Theorema.

Smarandache Curves of the Evolute Curve According to Sabban Frame
Communications in Advanced Mathematical Sciences, 2020 The aim of this paper is to define Smarandache curves according to the Sabban frame belonging to the unit Darboux vector of spherical indicatrix curve of the evolute curve. Also, we calculate the geodesic curvatures of these curves. Finally, the results are expressed depending on the involute curve.

Smarandache Curves of Mannheim Curve Couple According to Frenet Frame
Mathematical Sciences and Applications E-Notes, 2017 p>In this paper, when the unit Darboux vector of the partner curve of Mannheimnbsp;curve are taken as the position vectors, the curvature and the torsion of Smarandache curvenbsp;are calculated. These values are expressed depending upon the Mannheim curve. Besides,nbsp;we illustrate example of our main results./p>

Thermodynamics of the rainbow black string
四川大学学报. 自然科学版, 2019 Doubly special relativity (DSR) is an effective model to describe quantum gravity in flat spacetime. One way to incorporate this formalism into curved spacetime is the “rainbow gravity”, where the background spacetime is dependent on the energy of the ...
