Дифференциальная геометрия многообразий фигур, 2020 A compiled hyperplane distribution is considered in an n-dimensional projective space . We will briefly call it a -distribution. Note that the plane L(A) is the distribution characteristic obtained by displacement in the center belonging to the L ...

EPI-HYPOCYCLOIDS AND EPI-HYPOCYCLOIDAL CANAL SURFACES
Structural Mechanics of Engineering Constructions and Buildings, 2018 In the article are regarded the curves - epiand hypocycloids, which are formed by the moving of the generating points, linked with the circles of the same radius and which are at the same time outside and inside of the unmoving circle. There is shown the

Non-Destructive Evaluation of In-Plane Waviness in Carbon Fiber Laminates Using Eddy Current Testing
Applied Sciences, 2023 Non-destructive detection of the in-plane waviness of carbon fiber-reinforced plastic (CFRP) laminates is of interest in a wide variety of industries, as wrinkles and other fiber alignment defects significantly impact the mechanical performance of the ...

Tangent Lines and Planes in Topological Spaces [PDF]
Transactions of the American Mathematical Society, 1937 The object of this paper is to extend to topological spaces some of the concepts and theorems of direct infinitesimal geometry. To attain this object we define certain point sets in a topological space which will play the role of lines, planes, and hyperplanes in Euclidean space.

Stability Calculation of the Plane Steel Frame Structures Using Tangent Modulus Theory
Advances in Civil Engineering, 2023 This paper considers the phenomenon of the instability of steel plane frame structures in the elastic–plastic domain. The numerical analysis uses finite element method, where the corresponding stiffness matrices are based upon the trigonometric and ...

Model of motion of a material point near two tangent paraboloids [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe motion of a material point near a singularity of the type of two tangent surfaces is considered. The surfaces are located symmetrically with respect to a common tangent plane and have a common axis of rotation.

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
