Integer points enumerator of hypergraphic polytopes
(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2021)
For a hypergraphic polytope there is a weighted quasisymmetric
function which enumerates positive integer points in its normal fan
and determines its f −polynomial. This quasisymmetric function
invariant of hypergraphs ...
Weighted P-partitions enumerator
(Applicable Analysis and Discrete Mathematics, 2021)
To an extended generalized permutohedron we associate the weighted integer points enumerator, whose principal specialization is the f-polynomial. In the case of poset cones it refines Gessel's P-partitions enumerator. We ...
With the Chebyshev polynomials through geometric circulant matrices
(XIII Symposium MATHEMATICS AND APPLICATION, Faculty of Mathematics, University of Belgrade, 1-2 December, 2023, 2023)
We will present estimates for spectral norm bounds of the geometric circulant matrices whose entries are the Chebyshev polynomials of the first and the second kind. Some of the obtained results were verified by applying ...
Mixed Spearman’s Correlation Suitability for Sine-Shaped Independent Variables in Natural Sciences
(Institute of Electrical and Electronics Engineers Inc, 2023)
Pearson’s and Spearman’s methods are most often used in popular software packages to calculate the correlation coefficient between two variables in natural sciences. The (1) difference between them is that the Pearson’s ...
Софтверско-хардверско решење за естимацију термалног импулсног одзива вишеслојног равног зида
(Univerzitet u Beogradu, Građevinski Fakultet, 2020)
Comfort and elegance in auto design
(Serbian Society for Geometry and Graphics, University of Belgrade - Faculty of Mechanical Engineering, 2020)
Today, we are witnessing a strong combination between industry and art. It can even be argued that authentic artistic industry is being created, which consists of the manufacturing of products that combine useful qualities ...
Hankel determinants of the second order for some classes of analytic functions
(Akadémiai Kiadó’s journals, 2021)
Biodesign inspired by the leaf and flower of dandelion (leontodon taraxacum l.)
(Published by the AFGS2021 Organizing Committee, 2021)
Bionics is a scientific field that studies the laws of origin and structure of "living"
nature in combination with knowledge of biology and technology. By applying bionics, sustainable solutions and answers to the great ...
Interpreting parametric-biomimicry design from cad тo bim software: digital modelling based on a sketch of nandi flame
(Serbian Society for Geometry and Graphics (SUGIG) Faculty of Mechanical Engineering, University of Belgrade, 2021)
This research represents an application of two digital modelling softwares, first digital modelling software, chosen as representative of Computer-Aided Design – CAD modelling tool was Fusion 360. The representative of ...
Bohmian-Based Approach to Gauss-Maxwell Beams
(MDPI, 2020)
Usual Gaussian beams are particular scalar solutions to the paraxial Helmholtz equation,
which neglect the vector nature of light. In order to overcome this inconvenience, Simon et al.
(J. Opt. Soc. Am. A 1986, 3, 536–540) ...
