Biomimetic approach to parametric flower modeling
(19th International Conference on Geometry and Graphics 2021 ISGG, São Paulo, Brazil, 2021)
A sustainable design based on biomimicry can still fulfill the functional needs of humans and be
visually satisfying by representing man's connection to nature. Biomorphic means life, living forms,
it’s often associated ...
Improvement recommendations for railway infrastructure maintenance
(EDP Sciences, 2020)
Based on the railway network performance, Infrastructure Manager is obligated to define the Maintenance plan for railway infrastructure, which contains corresponding values for intervention limits and alert limits. This ...
Theory Of Interference Of Large Molecules
(AIP Conference Proceedings, 2007)
In the experiments with large molecules, the diameter of particles has approached the width of the slits. Therefore, a theoretical description of these cases should include a finite particle size. We are developing a theory ...
Concave Regular Faced Cupolae of Second Sort
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
Cupola is a polyhedron which is consisted of two regular polygons: n-gon and 2n-gon in parallel planes, connected by alternating sequence of squares and equilateral triangles, i.e. Johnson’s solids J3, J4 and J5. However, ...
Transposing an Octogonal Cupola of Second Sort Into a Bionic Polyspherical Form
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
In the paper there is presented a method of transposing a polyhedral structure, composed of two
regular polygons: octagon and hexadecagon as the bases, and the envelope formed of equilateral triangular strip, which is ...
Uniaxial compressive strength test before and after standard fire test on rock mass
(Engineering problems in soft rock / Fifth symposium of the Macedonian Association for Geotechnics, 2022)
The paper presents uniaxial compressive strength test according to SRPS EN 1926. Uniaxial
compressive strength test was performed on 12 identical cube-shaped specimen’s dimensions 70 mm x
70 mm x 70 mm, which are made ...
Possibilities of Deltahedral Concave Cupola Form Application in Architecture
(Iasi: The Gheorghe Asachi Technical University of Iasi, 2011)
In recent years, we are witnessing an increasing use of triangular modular building systems, which, especially in representative objects, almost push out the orthogonal system. Considering that deltahedra are assembled of ...
Generating Curves of Higher Order Using the Generalisation of Hügelschäffer’ Egg Curve construction
(Timişoara: Editura Politehnica, 2013)
The starting constructions is the well known ellipse construction using the concentric circles c1 and c2. By eccentricity of the center C2 for some value w, and for the preserved center of the transformation in the center ...
The impact of the Atmospheric Parameters at Electrooptical Distance Measurements
(International Federation of Surveyors, FIG, 2022)
The electro-optical distance measurement (EDM) instruments are widely used not only in geodesy but also in almost all engineering disciplines and related projects. High accuracy length measurements are required especially ...
Concave deltahedral rings based on the geometry of the concave antiprisms of the second sort
(Porto: Aproged - Associação dos Professores de Geometria e de Desenho, 2019)
We have shown that there is a link between the geometry of the CA II-nM’s with bases n∈{3, 4, 5} and that of the convex antiprisms with the same bases. An integer number (K) of CA II-nM’s fragments, can be used to form a ...
