Vizualizing of semi-regular polyhedrons in AutoCAD environment
Structural Mechanics of Engineering Constructions and Buildings, 2019 The paper examines the automated formation by the kinematic method of the surfaces of Archimedes' semi-regular polyhedra of three forms: truncated tetrahedron, truncated octahedron and truncated icosahedron.

UNFOLDED REGULAR AND SEMI-REGULAR POLYHEDRA
Journal of Industrial Design and Engineering Graphics, 2015 This paper proposes a presentation unfolding regular and semi-regular polyhedra. Regular polyhedra are convex polyhedra whose faces are regular and equal polygons, with the same number of sides, and whose polyhedral angles are also regular and equal ...

Modeling and visualizing of the formation of a snub dodecahedron in the AutoCAD system
Structural Mechanics of Engineering Constructions and Buildings, 2021 The article is devoted to modeling and visualization of the formation of flat-nosed (snub-nosed) dodecahedron (snub dodecahedron). The purpose of the research is to model the snub dodecahedron (flat-nosed dodecahedron) and visualize the process of its ...

A Real-Time Digital Twin for Human Cardiovascular Applications. [PDF]
Int J Numer Method Biomed EngA real‐time digital twin was developed using the reduced‐order unscented Kalman filter (ROUKF) to estimate left ventricular contractility from synthetic and in vivo left ventricular pressure measurement data. The results were promising, with identifiable parameter estimates and a stable mathematical model, highlighting the potential for real‐time ...

Visualizing surface formation of semi-regular polyhedra of Archimedes
Structural Mechanics of Engineering Constructions and Buildings, 2020 The most common method of forming semi-control polyhedra consists in cutting off angles and ribs of regular polyhedra by planes. The aim of the work - to consider the automated formation of a number of surfaces of semi-regular Archimedean polyhedra based

Any Regular Polyhedron Can Transform to Another by O(1) Refoldings [PDF]
, 2021 We show that several classes of polyhedra are joined by a sequence of O(1) refolding steps, where each refolding step unfolds the current polyhedron (allowing cuts anywhere on the surface and allowing overlap) and folds that unfolding into exactly the ...

Optimizing the Steffen flexible polyhedron [PDF]
, 2018 We revisit Steffen’s known flexible polyhedron, originally described in 1978, and investigate whether we can increase its range of motion by varying his original dimensions. We also define the regularity of a polyhedron.

Application of X-ray Microtomography to Quantify the Liquid Fraction of M2 Steel for Semi-solid Forming process [PDF]
, 2013 Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties.

Beyond Regular Semigroups [PDF]
, 2012 The topic of this thesis is the class of weakly U-abundant semigroups. This class is very wide, containing inverse, orthodox, regular, ample, adequate, quasi-adequate, concordant, abundant, restriction, Ehresmann and weakly abundant semigroups.
