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 ...
Hankel determinants of the second order for some classes of analytic functions
(Akadémiai Kiadó’s journals, 2021)
On the Generalized Strongly Nil - Clean Property of the Matrix Rings
(World Scientific Publishing Company, 2021)
Let R be an associative unital ring and not necessarily commutative. We
analyzes conditions under which every n×n matrix A over R is expressible as a sum
A = E1 + ... +Es +N of (commuting) idempotent matrices Ei and a ...
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 ...
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 ...
Hermitian Toeplicz determinants fr the class S of univalent functions
(National Academy of Sciences of the Republic of Armenia, 2021)
Introducing a new method, we give sharp estimates
of the Hermitian Toeplitz determinants of third order for the
class S of functions univalent in the unit disc. The new approach
is also illustrated on some subclasses ...
Circle in Space—Space in Circle: A Study of Ratio between Open Space and Built-Up Area in Historical Circular Objects
(MDPI, 2021)
Many cities nowadays explore different circular designs as new sustainable city concepts in different urban aspects. The new trend, as part of the adaptation for climate change, is a strategy of increasing the number of ...
Digital bio-transformations inspired by plants: urban installation as 3d model inspired by sketch of spathodea campanulata p. beauv (nandi flame)
(Faculty of Applied Arts, University of Arts in Belgrade, Serbia, 2021)
The field of biodesign, as an art and scientific discipline, deals with the exploration of the principles of organization and functioning of living organisms and the practical application of the acquired knowledge in ...
A Note on the Generalized Narayana’s Cows Sequence
(XI simpozijum "Matematika i primene", 2021)
The importance of integer sequences as well as structured matrices and their applications, motivated us to explore this topic. In particular, the Narayana’s cows sequence, which is closely related to the Fibonacci sequence, ...
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 ...
