Line geometry and 3D graphic statics [PDF]
Građevinar, 2019 The mathematical basis for the line geometry, with the line as its basic element, is presented in the paper because the forces that act on a body in space - whether we are interested in conditions of movement or immobility (balance) of that body - are ...

Surface Approximation by Means of Gaussian Process Latent Variable Models and Line Element Geometry [PDF]
Mathematics, 2023 The close relation between spatial kinematics and line geometry has been proven to be fruitful in surface detection and reconstruction. However, methods based on this approach are limited to simple geometric shapes that can be formulated as a linear ...

Angular Rolling of the Hollow Flanges of Pipe Joints
Metals, 2021 The paper considers a three-stage technology for angular rolling of the pipe workpiece. This technology facilitates the expansion of the range of flange parts available by eliminating a number of drawbacks of the known methods of metal forming.

Step-By-Step Modeling and Demetallation Experimental Study on the Porous Structure in Zeolites
Molecules, 2022 The organization of microporous space in zeolites is discussed. A new step-by-step model is proposed that explains the principles of organizing the hierarchy of microporous space at the stage of assembling zeolites from elements of minimal size: a ...

On the Angular Control of Rotating Lasers by Means of Line Calculus on Hyperboloids
Sensors, 2023 We propose a new paradigm for modelling and calibrating laser scanners with rotation symmetry, as is the case for lidars or for galvanometric laser systems with one or two rotating mirrors.
