Unordered multiplicity lists of wide double paths
(DMFA Slovenije, 2013)
Recently, Kim and Shader analyzed the multiplicities of the eigenvalues of a Φ-binary tree. We carry this discussion forward extending their results to a larger family of trees, namely, the wide double path, a tree consisting ...
Nonsingular acyclic matrices with full number of P-vertices
(Taylor & Francis Ltd, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
The maximum number of P-vertices of some nonsingular double star matrices
(Discrete Mathematics, 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order
n > 4 with n − 2 P-vertices. This example leads to a positive answer, for n > 6, to a last
open question proposed recently by ...
Konstruktivni postupci u prostornim transformacijama površi jednogranog eliptičkog hiperboloida / The Constructive procedures in the spatial transformations of the surface elliptical hyperboloid of one sheet
(Универзитет у Београду, Архитектонски факултет, 2013)
Једнограни елиптички хиперболоид (ЈЕХ) је најопштији случај површи двоструке закривљености, из породице правоизводних површи, која настаје клизањем једне трансверзале–генератрисе, дуж три директрисе – мимоилазне праве ...
Radius of univalence of certain class of analytic functions
(Faculty of Sciences and Mathematics, University of Niš, 2013)
Coefficient criteria for univalent and close-to-convex functions
(Graduate School of Information Sciences, Tohoku University, 2013)
In this paper, we provide sufficient conditions for constructing univalent analytic functions in the unit disk
jzj < 1. We motivate our results through several examples and compare with the previously known coefficient

Geometry of twisted surfaces applied on horizontal communications in architecture / Geometrija spiralnih površi primenjena na horizontalne komunikacije u arhitekturi
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
Contemporary technologies and materials continuously challenge structural designers, as well as architects, to achieve unique applications of various geometric surfaces. Twisted structures are actual and numerous in building ...
Generating a Type of Concave Cupolae of Fourth Sort
(Timişoara: Editura Politehnica, 2013)
The paper discusses the generation of a specific group of polyhedra, Concave Cupolae of Fourth Sort (CC IV) with regular polygonal bases, using constructive and analytical procedures. Beside determination of the parameters ...
