Angular Rolling of the Hollow Flanges of Pipe Joints
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.

Surface Approximation by Means of Gaussian Process Latent Variable Models and Line Element Geometry
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 ...

Step-By-Step Modeling and Demetallation Experimental Study on the Porous Structure in Zeolites
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
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.

SnO2-Based Porous Nanomaterials: Sol-Gel Formation and Gas-Sensing Application
Porous nanocomposites using two (tin dioxide–silica dioxide) and three (tin dioxide–indium oxide-silica dioxide)-component systems for gas sensors were created with the sol–gel method.

The Plumb-Line Matching Algorithm for UAV Oblique Photographic Photos
Building facades has always been a challenge for feature matching in oblique photogrammetry due to weak textures, non-Lambertian objects, severe occlusion, and distortion.

The GeoModel tool suite for detector description [PDF]
The GeoModel class library for detector description has recently been released as an open-source package and extended with a set of tools to allow much of the detector modeling to be carried out in a lightweight development environment, outside of large ...

Line Geometry and Camera Autocalibration [PDF]
We provide a completely new rigorous matrix formulation of the absolute quadratic complex (AQC), given by the set of lines intersecting the absolute conic. The new results include closed-form expressions for the camera intrinsic parameters in terms of the AQC, an algorithm to obtain the dual absolute quadric from the AQC using straightforward matrix ...
